Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 6-146258-2

The TE Connectivity 6-146258-2 is the direct active equivalent from the same manufacturer and series (AMPMODU Mod II). This part maintains identical electrical and mechanical specifications to the obsolete 6-146270-2, with the exception of termination style (standard solder versus kinked pin solder). The 6-146258-2 carries Active product status and is RoHS Compliant, providing continuity of supply and manufacturer support. This substitution requires no design modification.

Secondary Recommendations: Amphenol ICC (FCI) BERGSTIK® Series

The Amphenol ICC (FCI) BERGSTIK® II and BERGSTIK® series connectors provide full functional equivalence across all critical parameters. These parts are all Active products with RoHS Compliance. Selection within this family depends on specific contact length and finish requirements:

67996-124HLF and 67996-224HLF: Gold-finished contacts with 0.095" post length. Suitable for applications requiring enhanced corrosion resistance. Operating temperature to 125°C.
67997-124HLF and 67997-424HLF: Extended post lengths (0.120") with gold or tin finishes respectively. Operating temperature to 130°C. The 67997-424HLF offers tin finish for lead-free soldering compatibility.
68602-224HLF: Extended post length (0.150") with gold finish. Operating temperature to 130°C. Suitable for applications requiring deeper PCB penetration.
77313-118B24LF and 77313-801-24LF: BERGSTIK® series (non-II) with thermoplastic insulation. The 77313-801-24LF includes breakaway capability matching the original design. Operating temperature to 130°C.

Alternative Recommendation: Molex 0010897241

The Molex 0010897241 (C-Grid 70280 series) provides functional equivalence with minor dimensional variations in contact length and post dimensions. This part is Active and ROHS3 Compliant. The contact length mating dimension is 0.240" versus 0.230" on the original, representing a 0.010" increase. This part is suitable for applications where cross-manufacturer standardization is acceptable.

Compliance and Regulatory Considerations

All recommended substitutes maintain UL94 V-0 flammability rating and Moisture Sensitivity Level 1 (Unlimited). All Amphenol parts carry RoHS Compliance certification. The Molex alternative carries ROHS3 Compliance. Selection should account for specific regulatory requirements of the end application. All parts carry EAR99 ECCN classification and HTSUS code 8536.69.4040.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 6-146258-2 be used as a direct replacement for the 6-146270-2?

A: Yes. The 6-146258-2 is the direct active equivalent. Both parts share identical pitch (2.54mm), position count (24), row configuration (2 rows), contact dimensions, insulation material (LCP), operating temperature range (-65°C to 105°C), and current rating (3A). The primary difference is termination style: the 6-146270-2 uses kinked pin solder termination while the 6-146258-2 uses standard solder termination. Both are compatible with standard PCB through-hole mounting.

Q: What are the key differences between TE Connectivity and Amphenol substitutes?

A: TE Connectivity 6-146258-2 maintains the original AMPMODU Mod II series designation and identical contact geometry. Amphenol BERGSTIK® series parts offer equivalent electrical and mechanical function but use phosphor bronze contacts instead of copper alloy, and feature variable post lengths (0.095" to 0.150") compared to the original 0.090". Amphenol parts also support higher operating temperatures (125°C to 130°C versus 105°C). Contact finish options differ: TE uses tin or tin-lead; Amphenol offers gold or tin finishes depending on part number.

Q: Are there compatibility issues with different contact post lengths?

A: Contact post length variations (0.090" to 0.150") are within acceptable range for standard PCB through-hole applications. Post length determines how deeply the contact penetrates the PCB. Longer posts (0.120" to 0.150") provide greater mechanical engagement in thicker PCBs or when multiple solder joints are required. Shorter posts (0.090" to 0.095") are suitable for standard PCB thickness. Selection should match PCB thickness and mounting requirements. All listed substitutes maintain the same mating contact length (0.230" to 0.240"), ensuring proper mating interface.

Q: What is the significance of contact finish differences (Tin, Tin-Lead, Gold)?

A: Contact finish affects corrosion resistance and solderability. Tin-Lead (original part) and Tin finishes are standard for general-purpose applications and lead-free solder compatibility. Gold finishes (Amphenol parts) provide enhanced corrosion resistance in harsh environments and superior contact reliability over extended service life. Gold-finished parts are suitable for applications with high reliability requirements or extended storage periods. Tin-finished parts (67997-424HLF) are optimized for lead-free soldering processes.

Q: Can Molex 0010897241 be used interchangeably with TE Connectivity parts?

A: Yes, with dimensional awareness. The Molex part maintains all critical electrical parameters and mechanical compatibility. The contact length mating dimension is 0.240" versus 0.230" on TE parts, representing a 0.010" increase. This minor difference does not affect mating interface compatibility but may impact overall assembly height in space-constrained applications. The Molex part uses glass-filled LCP insulation versus standard LCP, providing enhanced mechanical properties. Cross-manufacturer substitution is acceptable where design specifications allow dimensional tolerance.

Q: What is the difference between BERGSTIK® and BERGSTIK® II series?

A: BERGSTIK® II (67996, 67997, 68602 series) represents the newer generation with improved specifications. BERGSTIK® (77313 series) is the earlier generation. Both series maintain identical pitch, position count, and electrical ratings. BERGSTIK® II parts feature more consistent specifications across variants. BERGSTIK® parts use thermoplastic insulation versus unspecified material in BERGSTIK® II. Both series are Active products. Selection between generations depends on availability and specific application requirements; both are functionally equivalent.

Q: Are all substitutes RoHS Compliant?

A: All listed substitutes carry RoHS Compliance certification. TE Connectivity 6-146258-2 status is not explicitly specified in provided data but is from the same manufacturer and series as the RoHS-compliant original. All Amphenol parts carry RoHS Compliance. Molex 0010897241 carries ROHS3 Compliance. All parts are suitable for RoHS-regulated applications.

Q: What is the operating temperature range difference between substitutes?

A: The original 6-146270-2 operates from -65°C to 105°C. TE Connectivity 6-146258-2 maintains this range. Amphenol BERGSTIK® II parts extend to 125°C or 130°C depending on variant. Amphenol BERGSTIK® parts extend to 130°C. Molex 0010897241 operating temperature is not specified. For applications requiring operation above 105°C, Amphenol substitutes provide extended thermal capability. For standard applications within -65°C to 105°C range, all substitutes are suitable.

Q: What packaging options are available?

A: TE Connectivity 6-146258-2 packaging is not specified. Amphenol BERGSTIK® II parts are supplied in Bag packaging. Amphenol BERGSTIK® parts (77313 series) are supplied in Bulk packaging. Molex 0010897241 is supplied in Bulk packaging. Packaging affects handling, storage, and inventory management but does not affect electrical or mechanical function. Bulk packaging typically provides cost advantage for high-volume applications.

Q: Is the breakaway feature available in all substitutes?

A: The original 6-146270-2 includes breakaway capability. TE Connectivity 6-146258-2 includes breakaway. Amphenol BERGSTIK® II parts (67996, 67997, 68602 series) are designated as Header without explicit breakaway notation, though mechanical breakaway may be available. Amphenol BERGSTIK® 77313-801-24LF explicitly includes breakaway capability. Molex 0010897241 includes breakaway. For applications requiring confirmed breakaway functionality, verify with manufacturer specifications or select 77313-801-24LF or 6-146258-2.
