Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 5-146257-3

The TE Connectivity 5-146257-3 is the direct equivalent replacement for the obsolete 4-146257-4. Both parts share identical electrical and mechanical specifications within the AMPMODU Mod II series. The 5-146257-3 is currently in active production status with substantial inventory availability (13,942 units). This part maintains RoHS compliance and is the preferred choice for direct substitution in existing designs.

Secondary Recommendations: Molex C-Grid Series

The Molex C-Grid 70280 and C-Grid 70287 series parts (0010897060, 0010897061, 0010897062, 0702800591, 0702871001, 0702871099) provide functional equivalence with minor dimensional variations. These parts are ROHS3 compliant and actively produced. Selection among these variants depends on specific contact length and post finish requirements:

0010897060, 0010897061, 0010897062: Standard post length (0.107" / 2.71mm) with varying contact finishes
0702800591: Extended post length (0.175" / 4.45mm) for applications requiring deeper board penetration
0702871001, 0702871099: Kinked pin termination (0.125" / 3.18mm post length) for enhanced mechanical retention

Tertiary Recommendations: Amphenol ICC BERGSTIK® Series

The Amphenol ICC 54102-G0803LF (BERGSTIK®) and 67996-306HLF (BERGSTIK® II) provide functional equivalence with extended operating temperature range (-65°C to 125°C). These parts feature phosphor bronze contacts and are RoHS compliant. The BERGSTIK® II variant (67996-306HLF) offers reduced contact post length (0.095" / 2.41mm).

Alternative: 3M 2306-6121-TP

The 3M 2306-6121-TP is functionally compatible but carries RoHS non-compliant status and REACH-affected designation. This part is suitable only for applications where RoHS compliance is not required. Operating temperature range is -55°C to 105°C, which is narrower than the main part specification.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 5-146257-3 be used as a direct replacement for the 4-146257-4?

A: Yes. The 5-146257-3 is the direct equivalent with identical specifications. The primary difference is product status: the 4-146257-4 is obsolete while the 5-146257-3 is actively produced. Both parts are RoHS compliant and share the same electrical and mechanical characteristics.

Q: What is the difference between the Molex C-Grid 70280 and C-Grid 70287 series?

A: The primary difference is termination type. C-Grid 70280 parts feature standard solder termination, while C-Grid 70287 parts feature kinked pin solder termination for enhanced mechanical retention. Contact post length also varies: C-Grid 70280 standard variants have 0.107" posts, while C-Grid 70287 variants have 0.125" posts.

Q: Are there compatibility issues with contact finish variations?

A: Contact finish variations (gold, tin, or tin-lead) do not affect electrical compatibility in standard applications. The mating interface determines performance. Gold-plated contacts provide superior corrosion resistance and are preferred for high-reliability applications. Tin-plated contacts are suitable for general-purpose applications with adequate environmental protection.

Q: What is the significance of the kinked pin termination in Molex 0702871001 and 0702871099?

A: Kinked pin termination provides mechanical retention during board assembly, reducing the risk of component displacement during soldering. This feature is beneficial in automated assembly processes or applications subject to vibration. Electrical performance is identical to standard solder termination.

Q: Can the Amphenol ICC BERGSTIK® parts be used in applications requiring -65°C operation?

A: Yes. Both the 54102-G0803LF and 67996-306HLF are rated for -65°C to 125°C operation, which exceeds the main part specification of -65°C to 105°C. These parts are suitable for extended temperature range applications.

Q: What is the difference between the Amphenol ICC 54102-G0803LF and 67996-306HLF?

A: The primary differences are contact post length and insulation height. The 54102-G0803LF has 0.120" post length and 0.100" insulation height, while the 67996-306HLF has 0.095" post length and 0.100" insulation height. Both feature identical mating contact length (0.230") and are functionally compatible.

Q: Is the 3M 2306-6121-TP suitable for new designs?

A: The 3M 2306-6121-TP is functionally compatible but carries RoHS non-compliant status. It is suitable only for applications where RoHS compliance is not required or for legacy system maintenance. For new designs, TE Connectivity 5-146257-3 or Molex/Amphenol alternatives are recommended.

Q: What is the impact of insulation material differences (LCP vs. Thermoplastic)?

A: Both Liquid Crystal Polymer (LCP) and thermoplastic materials meet UL94 V-0 flammability requirements. LCP provides superior dimensional stability and chemical resistance, while thermoplastic offers cost advantages. For standard applications, both materials are functionally equivalent.

Q: Are all substitute parts available in the same packaging formats?

A: Packaging varies by manufacturer and part number. TE Connectivity 5-146257-3 is available in bulk packaging. Molex parts are available in bulk. Amphenol ICC 54102-G0803LF is available in bag packaging. Packaging format does not affect electrical or mechanical compatibility; it affects only handling and storage procedures.

Q: What is the REACH compliance status of these parts?

A: TE Connectivity 5-146257-3 has undefined REACH status. Molex C-Grid parts are REACH Unaffected. Amphenol ICC 54102-G0803LF is REACH Affected. The 3M 2306-6121-TP is REACH Affected. REACH compliance requirements depend on application jurisdiction and end-use classification.
