Engineering Selection Recommendations
Primary Recommendation: TE Connectivity 7-146256-0
The TE Connectivity 7-146256-0 is the manufacturer-recommended upgrade from the obsolete 1-104351-7. This part maintains identical mating interface specifications and is classified as Active product status. The 7-146256-0 features RoHS Compliant certification, addressing regulatory requirements that the original part does not meet. The connector retains the same 40-position, 2-row configuration with 0.100" (2.54mm) pitch spacing and identical contact length specifications. The primary difference is the insulation material upgrade from Thermoplastic to Liquid Crystal Polymer (LCP), which provides improved thermal and mechanical performance. Current rating and operating temperature range remain equivalent to the original specification.
Secondary Recommendations: Molex C-Grid Series
The Molex C-Grid 70280 series (part numbers 0010897400, 0010897401, 0010897402, 0702800648, 0702800688) and C-Grid 70287 series (0702871214) provide functionally equivalent alternatives with Active product status and ROHS3 Compliant certification. These connectors maintain the critical mating interface parameters and are suitable for applications requiring regulatory compliance. The Molex alternatives feature Liquid Crystal Polymer (LCP) insulation material with glass filling, providing enhanced mechanical properties. Contact length specifications vary slightly across the Molex product line, with some variants offering extended post lengths (0.175" / 4.45mm) for applications requiring deeper PCB penetration.
Tertiary Recommendation: Amphenol ICC (FCI) 10076801-101-40LF
The Amphenol ICC (FCI) 10076801-101-40LF from the BERGSTIK® series provides an alternative from a different manufacturer with Active product status and RoHS Compliant certification. This connector maintains the same 40-position, 2-row configuration and mating interface. The part features Phosphor Bronze contact material and Thermoplastic insulation, similar to the original design. The operating temperature range extends to -65°C ~ 130°C, providing enhanced thermal capability. Current rating is specified as 3A per contact, matching the original specification.
Compliance Considerations:
All recommended substitute parts are classified as Active product status, ensuring ongoing availability and manufacturing support. The TE Connectivity 7-146256-0 is the direct manufacturer upgrade and is recommended for new designs and production continuity. Molex and Amphenol ICC alternatives are suitable for applications where multi-source qualification is required or where specific performance characteristics of these product lines are advantageous.
Frequently Asked Questions (FAQ)
Q: Can the TE Connectivity 7-146256-0 be used as a direct replacement for the 1-104351-7?
A: Yes. The 7-146256-0 maintains identical mating interface specifications including 40 positions, 2 rows, 0.100" (2.54mm) pitch, and equivalent contact length dimensions. The primary difference is the insulation material upgrade from Thermoplastic to Liquid Crystal Polymer (LCP) and RoHS compliance status. The connector is electrically and mechanically compatible with the original design.
Q: What are the key differences between the TE Connectivity 7-146256-0 and the Molex C-Grid alternatives?
A: The TE Connectivity 7-146256-0 maintains the original AMPMODU Mod II series design with Thermoplastic-equivalent performance through LCP insulation. Molex C-Grid connectors feature glass-filled LCP insulation, providing enhanced mechanical strength and thermal performance. Contact length specifications vary across the Molex product line, with some variants offering extended post lengths. Both product families maintain the same mating interface and are RoHS compliant.
Q: Are there any contact length considerations when selecting a substitute?
A: Yes. The original 1-104351-7 specifies a contact post length of 0.120" (3.05mm) with an overall contact length of 0.440" (11.18mm). The TE Connectivity 7-146256-0 maintains these specifications. Molex alternatives vary: the C-Grid 70280 series offers post lengths of 0.107" (2.71mm) or 0.175" (4.45mm) depending on the specific part number. The Amphenol ICC 10076801-101-40LF specifies a post length of 0.098" (2.50mm). Contact length differences may affect PCB design and should be verified for specific applications.
Q: What is the difference between kinked pin and standard solder termination?
A: The original 1-104351-7 features kinked pin solder termination, which provides mechanical retention during PCB assembly. All recommended substitute parts feature standard solder termination without the kinked pin feature. Standard solder termination is functionally equivalent for most applications and is the industry standard for modern connector designs. PCB design should accommodate standard through-hole solder termination.
Q: Are all substitute parts RoHS compliant?
A: The TE Connectivity 7-146256-0 is RoHS Compliant. The Molex C-Grid series parts are ROHS3 Compliant. The Amphenol ICC 10076801-101-40LF is RoHS Compliant. The original 1-104351-7 is RoHS non-compliant. For applications requiring RoHS compliance, any of the recommended substitutes are suitable.
Q: What packaging options are available for the substitute parts?
A: The TE Connectivity 7-146256-0 is supplied in Bulk packaging. Molex C-Grid alternatives are supplied in Bulk packaging. The Molex C-Grid 87914 series (0879144016) is supplied in Tray packaging. The Amphenol ICC 10076801-101-40LF is supplied in Bag packaging. Packaging selection should be based on production volume and assembly process requirements.
Q: Can the Molex C-Grid 70280 series with extended post length (0.175" / 4.45mm) be used in place of the original part?
A: The Molex C-Grid 70280 variants with extended post length (part numbers 0702800648, 0702800688) maintain the same mating interface and are mechanically compatible. However, the extended post length (0.175" / 4.45mm) compared to the original specification (0.120" / 3.05mm) requires PCB design verification. These variants are suitable for applications requiring deeper PCB penetration or where the extended post length provides design advantages.
Q: What is the operating temperature range for each substitute part?
A: The original 1-104351-7 and TE Connectivity 7-146256-0 both specify -65°C ~ 105°C. The Molex C-Grid series parts do not specify an operating temperature range in the provided data. The Amphenol ICC 10076801-101-40LF specifies -65°C ~ 130°C, providing extended high-temperature capability. For applications requiring operation above 105°C, the Amphenol ICC alternative is recommended.
Q: Are there any contact material differences between the substitute parts?
A: The original 1-104351-7 uses Copper Alloy contacts. The TE Connectivity 7-146256-0 uses Copper Alloy contacts. The Molex C-Grid series uses Copper Alloy contacts. The Amphenol ICC 10076801-101-40LF uses Phosphor Bronze contacts. Phosphor Bronze provides enhanced spring characteristics and contact durability. All contact materials are suitable for the specified electrical ratings.
Q: What is the current rating for each substitute part?
A: The original 1-104351-7 specifies 3A current rating. The TE Connectivity 7-146256-0 specifies 3A current rating. The Molex C-Grid series parts do not specify a current rating in the provided data. The Amphenol ICC 10076801-101-40LF specifies 3A per contact. For applications requiring confirmed current rating specifications, the TE Connectivity 7-146256-0 or Amphenol ICC 10076801-101-40LF are recommended.
