Engineering Selection Recommendations

Selection Criteria Based on Product Status and Compliance:

The 1-640441-6 and 4-640441-6 are functionally equivalent 16-position MTA-100 rectangular receptacle connectors with identical mechanical and electrical specifications. Both parts are active products from TE Connectivity AMP Connectors.

For applications with RoHS compliance requirements: The 4-640441-6 is the appropriate selection, as it carries ROHS3 compliance certification. The 1-640441-6 is RoHS non-compliant and is unsuitable for applications subject to RoHS directives.

For applications without RoHS compliance mandates: Either part may be selected based on availability and contact finish material compatibility. The 1-640441-6 features tin-lead contact finish; the 4-640441-6 features tin contact finish. Contact finish selection depends on application-specific solderability, corrosion resistance, and thermal cycling requirements.

For REACH-regulated applications: The 4-640441-6 carries REACH unaffected status, providing explicit compliance documentation. The 1-640441-6 has vendor-undefined REACH status and requires clarification before use in REACH-regulated supply chains.

Inventory and Packaging Considerations: The 4-640441-6 is available in bulk packaging with 7051 units in stock, compared to 1112 units of the 1-640441-6. Bulk packaging may provide cost advantages for high-volume procurement.

Frequently Asked Questions (FAQ)

Q: Are the 1-640441-6 and 4-640441-6 mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications: 16 positions, 0.100" pitch, female socket contacts, free-hanging right-angle mounting, locking ramp fastening, and closed-end design. They are mechanically interchangeable in applications where contact finish material and compliance status are not constraints.

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

A: The 1-640441-6 uses tin-lead contact finish; the 4-640441-6 uses tin contact finish. Both finishes are applied to the same 80.0µin (2.03µm) thickness. Contact finish selection affects solderability characteristics, corrosion resistance, and thermal cycling performance. Application requirements determine which finish is appropriate.

Q: Can I substitute the 1-640441-6 in a RoHS-compliant application?

A: No. The 1-640441-6 is RoHS non-compliant. For RoHS-regulated applications, the 4-640441-6 (ROHS3 compliant) is the required selection.

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

A: Yes. Both the 1-640441-6 and 4-640441-6 support IDC termination for discrete or ribbon cable at 24 AWG wire gauge.

Q: What is the significance of the base product number 640441?

A: The base product number 640441 identifies the core connector design. The prefix digits (1 or 4) distinguish packaging and compliance variants of the same base design. Both parts share the same base product number, confirming they are variants of the same connector family.

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

A: No. Both connectors carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without moisture control requirements.

Q: What is the difference in HTSUS classification between these parts?

A: The HTSUS codes differ (8536.69.4051 for 1-640441-6 and 8536.69.8000 for 4-640441-6) due to differences in contact finish material and packaging classification. This affects tariff and trade documentation but does not impact functional compatibility.

Q: Can I use these connectors with wire gauges other than 24 AWG?

A: No. Both connectors are specified for 24 AWG wire gauge only. IDC termination is designed for this specific gauge, and use with other gauges will result in improper contact engagement and connection failure.

Q: What mounting configurations are available?

A: Both connectors support free-hanging in-line and right-angle mounting orientations with locking ramp fastening. The mounting type is selected during connector assembly and cannot be changed after manufacturing.
