TE Connectivity AMP Connectors 641524-3 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 641524-3 is a 3 Position Rectangular Plug Connector designed for IDC (Insulation Displacement Contact) termination with 22 AWG discrete or ribbon cable. This connector operates as a male pin plug in the MTA-156 series and features tin-lead contact finish with feed-through capability. The part is currently active in production status and maintains RoHS compliance. Substitute parts are identified when equivalent electrical and mechanical parameters are required due to inventory availability, packaging preferences, or compliance specification changes.

Substitute Part Grouping Explanation

Substitution between the main part 641524-3 and the direct manufacturer equivalent 3-641524-3 is based on strict electrical and mechanical parameter equivalence. Both parts share identical specifications across all critical substitution criteria: connector type (plug), position count (3), pitch (0.156"), row configuration (1 row), contact type (male pin), cable termination method (IDC), wire gauge (22 AWG), wire type (discrete or ribbon cable), mounting type (free hanging in-line and right angle), feed-through feature, and contact finish thickness (80.0µin). The primary differences between these parts are contact finish composition (tin-lead versus tin) and packaging configuration (standard versus bulk). These differences do not affect functional interchangeability in applications where the connector specifications are met.

Engineering Selection Recommendations

Both 641524-3 and 3-641524-3 are active production parts from TE Connectivity AMP Connectors and maintain full RoHS compliance. The 641524-3 carries RoHS Compliant status, while the 3-641524-3 carries ROHS3 Compliant status, indicating both meet current regulatory requirements. Selection between these parts should be based on application requirements and packaging needs. The 641524-3 features tin-lead contact finish, while the 3-641524-3 features tin contact finish; both maintain identical contact finish thickness of 80.0µin (2.03µm). The 3-641524-3 is available in bulk packaging with significantly higher inventory (2974 pieces) compared to the 641524-3 (818 pieces), making it suitable for high-volume applications or production runs requiring bulk quantities. Both parts are functionally equivalent for applications requiring 3-position MTA-156 series rectangular plug connectors with IDC termination for 22 AWG cable.

Frequently Asked Questions (FAQ)

Q: Can 3-641524-3 be used as a direct replacement for 641524-3?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters including connector type, position count, pitch, contact type, cable termination method, wire gauge, and mounting configuration. The primary differences are contact finish composition (tin-lead versus tin) and packaging format (standard versus bulk).

Q: What is the difference between tin-lead and tin contact finish in these connectors?

A: The 641524-3 uses tin-lead contact finish while the 3-641524-3 uses tin contact finish. Both maintain identical contact finish thickness of 80.0µin (2.03µm). The contact finish material does not affect the mechanical or electrical compatibility of the connector in standard applications.

Q: Are both parts RoHS compliant?

A: Yes. The 641524-3 is RoHS Compliant and the 3-641524-3 is ROHS3 Compliant. Both meet current regulatory requirements for RoHS compliance.

Q: What is the significance of the packaging difference between these parts?

A: The 641524-3 is supplied in standard packaging while the 3-641524-3 is supplied in bulk packaging. The 3-641524-3 offers higher inventory availability (2974 pieces versus 818 pieces) and is suitable for applications requiring bulk quantities or high-volume production runs.

Q: Do these connectors support both discrete and ribbon cable?

A: Yes. Both the 641524-3 and 3-641524-3 support discrete or ribbon cable with 22 AWG wire gauge through IDC (Insulation Displacement Contact) termination.

Q: What mounting configurations are supported?

A: Both connectors support free hanging (in-line) and right angle mounting types, providing flexibility for various PCB and cable routing configurations.

Q: Is the feed-through feature present on both parts?

A: Yes. Both the 641524-3 and 3-641524-3 include feed-through capability as a standard feature.
