TE Connectivity 643815-5 Rectangular Connector Equivalent & Substitute Parts

Part Overview

The TE Connectivity 643815-5 is a 5-position rectangular receptacle connector from the MTA-100 series, designed for IDC (Insulation Displacement Contact) termination with 26 AWG discrete or ribbon cable. This connector features tin-lead contact finish, a closed-end design, and free-hanging or right-angle mounting configuration with locking ramp fastening. The part is currently active in production with 954 units in stock.

Substitute parts are identified to address specific compliance requirements, packaging preferences, or inventory availability while maintaining functional equivalence within the MTA-100 series.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 643815-5 is determined by strict equivalence across the following parameters:

• Connector Type & Series: Must be rectangular receptacle connector from MTA-100 series
• Position Count & Pitch: Must maintain 5 positions at 0.100" (2.54mm) pitch
• Contact Configuration: Must be female socket contacts
• Termination Method: Must support IDC termination
• Wire Compatibility: Must accept 26 AWG discrete or ribbon cable
• Mounting & Fastening: Must support free-hanging/right-angle mounting with locking ramp fastening
• Physical Design: Must feature closed-end construction

The substitute part 3-643815-5 meets all functional and mechanical requirements for direct substitution. The primary difference is the contact finish specification (tin versus tin-lead) and RoHS compliance status, which do not affect electrical or mechanical compatibility within the MTA-100 series framework.

Engineering Selection Recommendations

643815-5 (Tin-Lead Contact Finish)

Select this part number when:

• RoHS non-compliant designs are acceptable for the application
• Tin-lead contact finish is specified in design documentation
• Existing inventory or supply chain requirements mandate this specific contact finish

3-643815-5 (Tin Contact Finish, RoHS Compliant)

Select this part number when:

• RoHS compliance is required for the end application or market
• Tin contact finish meets design specifications
• Higher inventory availability is beneficial (31,722 units in stock versus 954 units)
• Bulk packaging is preferred over standard packaging

Both parts are functionally equivalent within the MTA-100 series and maintain identical electrical and mechanical characteristics. The selection between them is determined by compliance requirements and contact finish specifications rather than performance differences.

Frequently Asked Questions (FAQ)

Q: Are 643815-5 and 3-643815-5 directly interchangeable?

A: Yes. Both connectors are 5-position rectangular receptacles from the MTA-100 series with identical pitch, mounting configuration, IDC termination method, and 26 AWG wire compatibility. The primary difference is contact finish (tin-lead versus tin) and RoHS compliance status, which do not affect mechanical or electrical compatibility.

Q: What is the difference between tin-lead and tin contact finishes?

A: The 643815-5 features tin-lead contact finish, while the 3-643815-5 features tin contact finish. Both maintain the same 80.0µin (2.03µm) thickness. The contact finish difference does not affect connector mating, IDC termination, or electrical performance within the MTA-100 series.

Q: Which part should I select for RoHS-compliant applications?

A: The 3-643815-5 is RoHS compliant. The 643815-5 is RoHS non-compliant. Select based on your application's regulatory requirements.

Q: Are there packaging differences between these parts?

A: The 643815-5 is supplied in standard packaging, while the 3-643815-5 is supplied in bulk packaging. Both are new original stock from TE Connectivity.

Q: Can these connectors be used with both discrete and ribbon cable?

A: Yes. Both the 643815-5 and 3-643815-5 support discrete or ribbon cable at 26 AWG wire gauge with IDC termination.

Q: What is the pitch specification for these connectors?

A: Both connectors maintain a 0.100" (2.54mm) pitch, which is the standard spacing for MTA-100 series rectangular connectors.

Q: Are these connectors suitable for free-hanging or right-angle mounting?

A: Yes. Both connectors support free-hanging (in-line) and right-angle mounting configurations with locking ramp fastening.
