Question 1

What is the Mfr

Accepted Answer

Mfr refers to the component's producing company, whose brand and manufacturing processes directly impact the component's performance, consistency, and traceability, making it a key reference during selection.

Question 2

What is the Series

Accepted Answer

Series indicates a manufacturer’s organized range of components, often named with a common prefix or code, to streamline product selection and ensure compatibility across similar models.

Question 3

What is the Package

Accepted Answer

his term denotes the protective casing (often made of plastic, ceramic, or metal) that encapsulates an integrated circuit, determining its size, reliability, and suitability for different mounting technologies like through-hole or SMT.

Question 4

What is the Base Product Number

Accepted Answer

By using the Base Product Number, manufacturers and customers can efficiently communicate about component families without detailing every specification, streamlining the procurement process.

Question 5

What is the Product Status

Accepted Answer

Product Status indicates the commercial availability and production stage of the component, such as Active, Not for New Design (NRND), Obsolete, or Last Time Buy (LTB).

Question 6

What is the Number of Rows

Accepted Answer

It specifies the count of parallel contact or pin arrays in a connector, switch, or IC package, directly determining the total pin count when multiplied by the number of columns. This dimension is critical for defining the component's footprint, mating in

Question 7

What is the Number of Positions

Accepted Answer

This parameter specifies the total count of individual, electrically distinct connection points or terminals available within a single connector, switch, relay, or terminal block. It defines the maximum number of discrete circuits or wires the component c

Question 8

What is the Length - Overall Pin

Accepted Answer

This parameter specifies the total axial dimension of a component's electrical lead, measured from its tip to the shoulder where it meets the package body. It is a critical mechanical dimension that determines the lead's protrusion through a PCB, influenc

Question 9

What is the Length - Post (Mating)

Accepted Answer

This dimension specifies the axial length of the pin or post segment that extends from the connector body and is designed to engage with a mating socket or receptacle. It is a critical mechanical parameter that determines the depth of insertion, ensuring

Question 10

What is the Length - Stack Height

Accepted Answer

This dimension specifies the total vertical distance from the mounting surface (e.g., PCB) to the top of a component after it is fully seated, including its body and any integral mounting features like standoffs or flanges. It is a critical mechanical par

Question 11

What is the Length - Tail

Accepted Answer

This parameter specifies the axial dimension of the uninsulated, conductive portion of a component's lead or terminal that extends beyond its main body or sealing point. It defines the length available for mechanical insertion, soldering, or crimping into

Question 12

What is the Color

Accepted Answer

A visual attribute determined by the wavelength of light reflected or emitted, used for rapid identification, polarity marking, functional grouping (e.g., resistor bands, LED emission, wire jackets), and status indication of components within a system.

Question 13

What is the Row Spacing

Accepted Answer

Row Spacing refers to the center-to-center distance between adjacent rows of pins or contacts in a multi-row connector or component. This dimension, typically measured in millimeters (mm), is critical for defining the component's footprint on a PCB, ensur

Question 14

What is the Termination

Accepted Answer

The specific method and hardware used to establish a permanent or semi-permanent electrical and mechanical connection at the end of a wire, cable, or component lead. Common methods include soldering, crimping, screw clamping, insulation displacement, and

Question 15

What is the Mounting Type

Accepted Answer

Mounting Type refers to the standardized classification of the method by which an electronic component or module is physically secured and electrically connected to a printed circuit board, chassis, or panel. It defines how the component integrates into t

Question 16

What is the Pitch

Accepted Answer

The nominal center-to-center distance between adjacent pins, pads, or contacts on a component, connector, or across a PCB. Measured in millimeters or inches, it is a fundamental dimensional parameter that dictates component footprint, PCB trace routing de

Question 17

What is the Contact Finish - Post (Mating)

Accepted Answer

This specification defines the surface treatment applied to the electrical contacts *after* the mating cycle has occurred, typically referring to the base material exposed due to wear of the initial plating. Its primary function is to ensure long-term rel

Question 18

What is the Contact Finish Thickness - Post (Mating)

Accepted Answer

This parameter specifies the thickness of the metallic plating layer applied to the contact surfaces after the mating process is complete. It is a critical measure of the remaining protective or conductive coating (e.g., gold, tin) following wear cycles,
