Engineering Selection Recommendations

Primary Recommendation: TE Connectivity 6-146256-0

The 6-146256-0 is the manufacturer-recommended upgrade from the obsolete 1-104351-0. Both parts share identical electrical and mechanical specifications with the exception of post finish material (tin versus tin-lead) and insulation material (LCP versus thermoplastic). The 6-146256-0 is active, ROHS3 compliant, and maintains the same 0.120" contact post length. This part is the direct functional equivalent and is preferred for new designs and obsolescence replacement.

Secondary Recommendation: Amphenol ICC 10076801-101A20LF

The 10076801-101A20LF offers extended operating temperature range (-65°C to 130°C) and is supplied in tape and reel packaging suitable for automated assembly. Contact post length is 0.098", which is within acceptable tolerance for standard board depths. This part is RoHS compliant and active. Selection is appropriate when higher temperature performance or automated placement is required.

Tertiary Recommendations: Sullins Connector Solutions PBC10 Series

The Sullins PBC10DAAN, PBC10DABN, PBC10DACN, PBC10DADN, PBC10DAEN, PBC10DAFN, and PBC10DAHN variants provide functional equivalence with variable contact post lengths ranging from 0.120" to 0.820". All variants are ROHS3 compliant, active, and rated for 3A at -65°C to 125°C. Selection among these variants is determined by application-specific board depth requirements. The PBC10DAAN (0.120" post length) is the closest mechanical match to the original part.

Alternative: Molex 0010897202

The 0010897202 provides functional equivalence with glass-filled LCP insulation material and is suitable for applications requiring enhanced mechanical properties. Contact post length is 0.107", and the part is ROHS3 compliant and active. This option is appropriate when superior insulation material performance is required.

All recommended substitutes maintain the critical parameters of 20-position, 2-row, 2.54mm pitch configuration with gold-plated mating contacts, solder termination, and UL94 V-0 flammability rating.

Frequently Asked Questions (FAQ)

Q: Can the 1-104351-0 be directly replaced with the 6-146256-0?

A: Yes. The 6-146256-0 is the manufacturer-recommended replacement. Both parts share identical connector type, contact configuration, pitch, mounting method, and current rating. The primary differences are post finish material (tin versus tin-lead) and insulation material (LCP versus thermoplastic), both of which are acceptable substitutions for standard applications.

Q: What is the significance of contact post length variations in the Sullins PBC10 series?

A: Contact post length determines the maximum board thickness that can be accommodated. The original 1-104351-0 features a 0.120" post length. Sullins variants range from 0.120" (PBC10DAAN) to 0.820" (PBC10DAHN). Selection is based on the specific board depth of the application. Longer post lengths accommodate thicker PCBs or additional stacking height requirements.

Q: Are all substitute parts RoHS compliant?

A: The original 1-104351-0 is RoHS non-compliant. All recommended substitutes are either ROHS3 compliant or RoHS compliant. For applications requiring RoHS compliance, any of the recommended substitutes are acceptable.

Q: What is the difference between tin and tin-lead post finish?

A: Both finishes provide equivalent electrical and mechanical performance for solder termination. Tin-lead finish (original part) contains lead, while tin finish (substitute parts) is lead-free. Tin finish is preferred for RoHS-compliant applications and modern manufacturing processes.

Q: Can I use a substitute part with a different insulation material?

A: Yes. The original part uses thermoplastic insulation, while substitutes employ LCP or PBT materials. All materials meet UL94 V-0 flammability requirements. Material selection does not affect electrical performance for standard applications. LCP and PBT offer superior mechanical and thermal properties compared to thermoplastic.

Q: What is the operating temperature range consideration for substitute selection?

A: The original part operates from -65°C to 105°C. Most substitutes extend this range to -65°C to 125°C or -65°C to 130°C. Substitutes with extended temperature ranges are backward compatible with the original specification and provide additional margin for demanding thermal environments.

Q: Are there packaging differences between substitute parts?

A: Yes. The 6-146256-0 is supplied in bulk packaging. The 10076801-101A20LF is supplied in tape and reel format, suitable for automated pick-and-place assembly. Sullins parts are supplied in bulk. Packaging selection depends on assembly method and volume requirements.

Q: Can the 1-104351-0 be used interchangeably with all listed substitutes in existing designs?

A: The 6-146256-0 and Amphenol ICC 10076801-101A20LF are direct functional equivalents. Sullins variants require verification of contact post length compatibility with board thickness. Molex 0010897202 is functionally equivalent but uses glass-filled LCP insulation. All substitutes maintain the critical 20-position, 2-row, 2.54mm pitch configuration and are mechanically compatible with standard mating connectors.

Q: What certifications should I verify for my specific application?

A: All recommended substitutes carry UL94 V-0 flammability certification. RoHS and REACH compliance status varies by part. Verify RoHS compliance requirements for your application. The 10076801-101A20LF carries REACH Affected status, while Sullins parts carry REACH Unaffected status. Consult application-specific regulatory requirements before final part selection.
