Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TE Connectivity 641239-5 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (5)
• Pitch (0.100" / 2.54mm)
• Number of rows (1)
• Mounting type (Free Hanging, In-Line, Right Angle)
• Cable termination method (IDC)
• Wire gauge compatibility (26 AWG)
• Contact finish (Gold)
• Contact finish thickness (30.0µin / 0.76µm)
• Closed-end design
• Series designation (MTA-100)

The substitute part 3-641239-5 maintains complete electrical and mechanical equivalence across all specified parameters. The primary distinction between the main part and its substitute is product status: the original 641239-5 is obsolete, while 3-641239-5 is active and currently in production. Both parts share identical base product number 641239 and are manufactured by TE Connectivity AMP Connectors.

Parameter Comparison

Engineering Selection Recommendations

The part 3-641239-5 is the direct equivalent substitute for the obsolete 641239-5. Selection of the active substitute is based on the following engineering criteria:

Product Status: The original 641239-5 is classified as obsolete, which restricts long-term availability and support. The substitute 3-641239-5 maintains active production status, ensuring continued supply chain access and manufacturing support.

Compliance Certification: Both parts maintain RoHS compliance. The main part carries ROHS3 certification, while the substitute carries RoHS certification. Both designations confirm lead-free and restricted substance compliance suitable for current regulatory requirements.

Electrical and Mechanical Equivalence: The substitute part maintains complete parameter equivalence across all connector specifications, including contact configuration, termination method, wire gauge compatibility, and contact finish specifications. No functional or performance differences exist between the two parts.

Inventory and Availability: The substitute part 3-641239-5 has 3,475 pieces in current stock, compared to 2,501 pieces of the obsolete main part. Selection of the active substitute ensures access to ongoing inventory replenishment.

For new designs, field service applications, and production continuity, the part 3-641239-5 is the appropriate selection. Existing assemblies using 641239-5 are directly compatible with 3-641239-5 without modification or redesign.

Frequently Asked Questions (FAQ)

Q: Can 3-641239-5 be used as a direct replacement for 641239-5 in existing assemblies?

A: Yes. The parts are electrically and mechanically identical across all specified parameters. No modifications to mating connectors, cable assemblies, or PCB layouts are required. Direct substitution is supported.

Q: What is the significance of the "3-" prefix in the part number 3-641239-5?

A: The "3-" prefix indicates a variant designation within the TE Connectivity product line. Both 641239-5 and 3-641239-5 share the same base product number (641239) and are functionally equivalent. The prefix does not indicate a different connector type or performance level.

Q: Are there any differences in RoHS compliance between the two parts?

A: Both parts are RoHS compliant. The main part carries ROHS3 certification, while the substitute carries RoHS certification. Both meet current regulatory requirements for lead-free and restricted substance compliance. No functional difference exists in environmental compliance status.

Q: What wire gauges are compatible with these connectors?

A: Both connectors are specified for 26 AWG wire. The IDC termination method accommodates discrete or ribbon cable configurations at this gauge. Wire gauge selection outside this specification is not supported by these connector designs.

Q: Is the contact finish thickness identical between the two parts?

A: Yes. Both parts feature gold-plated contacts with a finish thickness of 30.0µin (0.76µm). Contact resistance, durability, and electrical performance are equivalent.

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

A: Yes. Both the main part and substitute support discrete or ribbon cable termination via the IDC method. The connector design accommodates either cable configuration without modification.

Q: What is the pitch specification, and why is it important for substitution?

A: The pitch is 0.100" (2.54mm), representing the center-to-center distance between adjacent contact positions. This specification must match exactly for mechanical compatibility with mating connectors and PCB layouts. Both parts maintain identical pitch specifications.

Q: Are there any moisture sensitivity concerns with these connectors?

A: Both parts carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without special moisture control measures. No desiccant storage or baking procedures are required prior to assembly.

Q: What mounting configurations are supported?

A: Both connectors support free-hanging (in-line) and right-angle mounting types. The locking ramp fastening mechanism provides secure cable retention in both orientations.
