Engineering Selection Recommendations

TE Connectivity 5-146257-8 (Primary Substitute)

The 5-146257-8 is the recommended primary substitute for the obsolete 5-146269-8. Both components are manufactured by TE Connectivity within the AMPMODU Mod II series and share identical electrical and mechanical specifications. The 5-146257-8 maintains active product status, ensuring continued availability and supply chain stability. The primary distinction is termination configuration: the 5-146269-8 features kinked pin termination while the 5-146257-8 uses standard solder termination. Both achieve equivalent solder joint reliability through different mechanical approaches. The 5-146257-8 carries ROHS3 compliance, representing current regulatory alignment. Inventory availability of 5,372 pieces supports production requirements.

Sullins Connector Solutions PBC08DAAN (Secondary Substitute)

The PBC08DAAN serves as an alternative substitute from a different manufacturer. This component maintains all mandatory electrical and mechanical parameters including 16-position, 2-row configuration at 2.54mm pitch, through-hole mounting, and 3A current rating. Acceptable variations include phosphor bronze contact material (versus copper alloy), polybutylene terephthalate insulation (versus LCP), and extended operating temperature range to 125°C. The contact finish thickness on mating surfaces is reduced to 10.0µin compared to 30.0µin on the primary substitute, and overall contact length is 0.010" greater. The PBC08DAAN carries ROHS3 compliance and REACH Unaffected status. This option provides supply diversification and extended thermal performance for applications requiring operation above 105°C.

Selection Criteria

For direct replacement in existing designs, the TE Connectivity 5-146257-8 is the appropriate choice due to series continuity and identical specifications. The Sullins PBC08DAAN is suitable for new designs or applications where extended temperature performance or supply chain diversification is required. Both substitutes maintain the critical electrical parameters of 3A current rating, gold-plated mating contacts, and UL94 V-0 flammability compliance.

Frequently Asked Questions (FAQ)

Q: Can the 5-146257-8 directly replace the 5-146269-8 in existing assemblies?

A: The 5-146257-8 is electrically and mechanically equivalent to the 5-146269-8 for all functional parameters. The primary difference is termination style: kinked pin versus standard solder. Both achieve equivalent solder joint performance. Direct substitution is supported for board-to-board and cable applications.

Q: What is the significance of the kinked pin termination on the 5-146269-8?

A: Kinked pin termination provides mechanical retention during assembly, reducing solder joint stress during insertion and vibration. The 5-146257-8 standard solder termination achieves equivalent reliability through different mechanical design. Both configurations are suitable for the same applications.

Q: Why does the PBC08DAAN have a lower gold plating thickness on mating contacts?

A: The PBC08DAAN specifies 10.0µin gold plating versus 30.0µin on the TE Connectivity parts. Both thicknesses provide adequate corrosion protection and contact reliability for 3A current applications. The reduced thickness represents a design variation acceptable within industry standards for this connector class.

Q: Is the PBC08DAAN suitable for applications requiring operation above 105°C?

A: The PBC08DAAN operates to 125°C, extending the upper temperature limit by 20°C compared to the 5-146269-8 and 5-146257-8. This extended range is achieved through polybutylene terephthalate insulation material. Applications requiring sustained operation above 105°C should specify the PBC08DAAN.

Q: What is the impact of insulation material differences between LCP and PBT?

A: Both liquid crystal polymer and polybutylene terephthalate are thermoplastic insulation materials meeting UL94 V-0 flammability requirements. LCP provides superior dimensional stability and lower moisture absorption. PBT offers cost efficiency and extended temperature performance. Both materials are suitable for the specified electrical and mechanical requirements.

Q: Are all three parts RoHS compliant?

A: The 5-146269-8 carries RoHS Compliant status. The 5-146257-8 and PBC08DAAN carry ROHS3 Compliant status, representing current regulatory alignment. All three parts are suitable for RoHS-regulated applications.

Q: What is the difference in overall contact length between the parts?

A: The 5-146269-8 and 5-146257-8 specify 0.440" overall contact length. The PBC08DAAN specifies 0.450", a 0.010" difference. This variation reflects different manufacturing approaches and does not affect electrical performance or board-level compatibility for standard through-hole applications.

Q: Can the PBC08DAAN be used in applications originally designed for the 5-146269-8?

A: The PBC08DAAN is functionally equivalent for all critical electrical and mechanical parameters. The acceptable variations in contact material, insulation material, and dimensional tolerances do not compromise performance in applications designed for the 5-146269-8. Verification of board layout compatibility is recommended due to minor dimensional differences.

Q: What is the moisture sensitivity level significance?

A: The 5-146269-8 and 5-146257-8 specify MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. The PBC08DAAN specifies Not Applicable, indicating the component does not require moisture sensitivity classification. Both approaches are suitable for standard storage and assembly conditions.

Q: Are there supply chain advantages to selecting one substitute over another?

A: The 5-146257-8 offers 5,372 pieces in stock from the original manufacturer, ensuring supply continuity within the TE Connectivity product line. The PBC08DAAN offers 3,972 pieces from Sullins Connector Solutions, providing supply diversification. Selection should consider production volume requirements and supply chain strategy.
