Engineering Selection Recommendations

Primary Substitutes (Highest Compatibility):

The Molex 0010897402 rectangular connector header represents the closest functional equivalent to the TE Connectivity 1-103675-2. This part maintains identical pitch spacing (2.54mm), position count (40), row configuration (2), and mounting methodology (through-hole solder). The 0010897402 features gold-plated mating contacts matching the original specification and operates within the same mechanical envelope. The part carries ROHS3 compliance status, addressing regulatory requirements absent in the obsolete original component.

The Amphenol ICC 10076801-101-40LF BERGSTIK® series connector provides functional equivalence with thermoplastic insulation material identical to the original part. This component maintains the same contact length specifications (5.84mm mating, 2.50mm post) and overall contact length (11.18mm), ensuring direct mechanical compatibility. The part is RoHS compliant and rated for -65°C to 130°C operating temperature with 3A per contact current rating.

Secondary Substitutes (Acceptable Variations):

The Molex C-Grid 70280 series parts (0010897400, 0010897401, 0010897402, 0702800608, 0702800648, 0702800688) provide functional substitution with minor contact length variations. These parts feature extended post lengths (2.71mm to 4.45mm) compared to the original 3.05mm specification, accommodating deeper PCB mounting applications. All maintain identical pitch, position count, and row spacing parameters. The C-Grid 70287 variant (0702871214) incorporates kinked pin termination in addition to solder termination, offering alternative assembly methodologies.

The Preci-Dip 450-V3-240-00-006101 connector operates within acceptable mechanical tolerances with circular contact geometry rather than square contacts. This part features reduced mating contact length (3.60mm) and operates at -55°C to 125°C with 3A current rating and 150VDC voltage rating.

Compliance Considerations:

All recommended substitute parts carry active product status and ROHS3 compliance certification. The original TE Connectivity 1-103675-2 is classified as RoHS non-compliant and obsolete. Selection of substitute components should prioritize active status parts to ensure long-term supply chain availability and regulatory alignment with current environmental standards.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0010897402 directly replace the TE Connectivity 1-103675-2 in existing designs?

A: The Molex 0010897402 maintains identical electrical and mechanical parameters for pitch spacing, position count, row configuration, and mounting type. The mating contact length increases from 5.84mm to 6.10mm, and the post length decreases from 3.05mm to 2.71mm. These variations remain within acceptable mechanical tolerances for standard PCB applications. Verification of specific board layout requirements is necessary to confirm compatibility.

Q: What is the primary difference between Molex C-Grid 70280 variants?

A: The C-Grid 70280 series includes three primary variants distinguished by contact finish specifications. Part 0010897400 features gold-plated mating contacts with tin-plated posts. Part 0010897401 uses tin plating for both mating and post contacts. Part 0010897402 combines gold-plated mating contacts with tin-plated posts. All three maintain identical mechanical dimensions and electrical characteristics. Selection depends on specific corrosion resistance and solderability requirements.

Q: How do the extended post length variants (0702800608, 0702800648, 0702800688) differ from standard C-Grid 70280 parts?

A: These variants feature 0.175" (4.45mm) post length compared to the standard 0.107" (2.71mm) specification. The extended post length accommodates deeper PCB mounting applications and provides increased solder joint engagement. Overall contact length increases from 11.10mm to 12.83mm. These parts are suitable for applications requiring deeper component penetration through PCB assemblies.

Q: What is the significance of kinked pin termination in the Molex 0702871214?

A: The 0702871214 incorporates kinked pin termination in addition to standard solder termination. This feature provides mechanical retention during assembly and reduces stress on solder joints during thermal cycling. The kinked pin design maintains compatibility with standard PCB through-hole mounting while offering enhanced mechanical stability.

Q: Is the Amphenol ICC 10076801-101-40LF suitable for high-temperature applications?

A: The 10076801-101-40LF operates within -65°C to 130°C temperature range with 3A per contact current rating. This specification supports standard industrial and commercial temperature environments. Applications requiring extended temperature ranges beyond 130°C require evaluation of alternative component specifications.

Q: What packaging considerations apply when selecting substitute parts?

A: The original TE Connectivity 1-103675-2 is supplied in bulk packaging. Substitute parts are available in multiple packaging formats including bulk, tray, and bag configurations. Packaging selection affects component handling, storage, and automated assembly compatibility. Verify packaging specifications align with production line requirements and inventory management systems.

Q: How do contact material differences affect connector performance?

A: The original part uses copper alloy contacts. Substitute parts employ copper alloy, phosphor bronze, or brass contact materials. Phosphor bronze (Amphenol ICC 10076801-101-40LF) provides enhanced spring characteristics and corrosion resistance. Brass (Preci-Dip 450-V3-240-00-006101) offers improved machinability and cost efficiency. All materials maintain electrical conductivity within acceptable parameters for standard signal and power applications.

Q: Are all substitute parts RoHS compliant?

A: All recommended substitute parts carry ROHS3 compliance certification. The original TE Connectivity 1-103675-2 is classified as RoHS non-compliant. Regulatory requirements in most jurisdictions mandate use of RoHS-compliant components for new designs and production. Existing legacy systems may continue using non-compliant components, but new procurement should prioritize compliant alternatives.
