Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compliance):

The Amphenol ICC 79257-114HLF and 3M 2314-5121TG represent the most direct functional equivalents to the TE Connectivity 104353-7. Both parts are currently in active production status and maintain identical core mechanical and electrical interface specifications. The 79257-114HLF offers an extended operating temperature range (-65°C ~ 130°C) compared to the original part, providing additional thermal margin for demanding applications. The 3M 2314-5121TG maintains the same operating temperature floor as the original specification.

Secondary Substitutes (Active Status, Minor Variations):

The Molex C-Grid III series parts (0901220767 and 0901220927) are active production alternatives that maintain all critical interface parameters. These parts feature slightly longer mating contact lengths (0.266" versus 0.230") and different insulation material composition (polyester glass-filled versus thermoplastic). The 0901220927 matches the original gold plating thickness specification (30.0µin), while the 0901220767 features reduced plating thickness (15.0µin). Both Molex parts achieve ROHS3 compliance and REACH unaffected status, representing improved regulatory positioning compared to the obsolete original part.

Compliance Considerations:

The original TE Connectivity 104353-7 is RoHS non-compliant and REACH affected. All substitute parts listed achieve either RoHS3 compliance or RoHS compliance status. For applications subject to RoHS or REACH regulatory requirements, the Molex alternatives (0901220767, 0901220927) provide the highest compliance level with ROHS3 certification and REACH unaffected designation. The Amphenol 79257-114HLF and 3M 2314-5121TG maintain RoHS compliance but retain REACH affected status.

Thermal Performance:

Applications requiring operation at temperatures below -65°C or above 105°C should specify the Amphenol 79257-114HLF, which supports -65°C ~ 130°C operation. The 3M 2314-5121TG supports -55°C ~ 105°C, which is suitable for standard industrial temperature ranges but does not extend below -65°C.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0901220767 directly replace the TE Connectivity 104353-7 in existing designs?

A: The Molex 0901220767 maintains all critical interface specifications including 14 positions, 2-row configuration, 0.100" pitch, male pin contacts, through-hole right-angle mounting, and square contact geometry. The mating contact length is 0.266" compared to 0.230" in the original part. This dimensional difference must be evaluated against mating receptacle depth specifications in the target application. The reduced gold plating thickness (15.0µin versus 30.0µin) is within industry standards for gold-plated contacts.

Q: What is the primary advantage of the Amphenol 79257-114HLF over the original TE part?

A: The Amphenol 79257-114HLF maintains identical mating contact length (0.230"), post contact length (0.120"), and gold plating thickness (30.0µin) specifications as the TE Connectivity 104353-7. The primary advantage is extended operating temperature range (-65°C ~ 130°C versus -65°C ~ 105°C) and active production status with RoHS compliance. The BERGSTIK® II series design provides proven reliability in automotive and general-purpose applications.

Q: Are there differences in contact material between the substitute parts?

A: Yes. The original TE Connectivity 104353-7 uses copper alloy contacts. The Molex C-Grid III series (0901220767, 0901220927) uses brass contacts. The Amphenol 79257-114HLF uses phosphor bronze contacts. The 3M 2314-5121TG uses copper alloy contacts. All materials are suitable for the specified 3A current rating and 30VAC voltage application. Contact material selection does not affect mechanical or electrical interface compatibility.

Q: Which substitute part offers the best regulatory compliance for new designs?

A: The Molex 0901220927 and Molex 0901220767 offer the highest regulatory compliance with ROHS3 certification and REACH unaffected status. These parts are recommended for applications subject to European Union RoHS Directive 2011/65/EU (as amended by 2015/863/EU) and REACH Regulation (EC) 1907/2006 requirements. Both parts maintain identical core specifications and are available in active production.

Q: What packaging options are available for the substitute parts?

A: The Molex 0901220767 is supplied in bulk packaging. The Amphenol 79257-114HLF is supplied in bag packaging. The Molex 0901220927 and 3M 2314-5121TG packaging specifications are not detailed in available documentation. Packaging selection should be coordinated with procurement and assembly process requirements.

Q: Are all substitute parts suitable for board-to-board applications?

A: Yes. All substitute parts listed are specified for board-to-board or cable applications. The Amphenol 79257-114HLF is specifically designated for board-to-board style applications. All parts feature identical push-pull fastening mechanisms and unshrouded header design suitable for standard PCB mounting and mating with compatible receptacles.

Q: What is the moisture sensitivity level for all substitute parts?

A: The TE Connectivity 104353-7, Molex 0901220767, Molex 0901220927, and Amphenol 79257-114HLF all carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity precautions are required during storage, handling, or assembly. The 3M 2314-5121TG is rated as Not Applicable for moisture sensitivity.
