Allowable Variations: Substitute parts may differ in contact finish composition, contact finish thickness, insulation material, insulation height, overall contact length, and operating temperature maximum. These variations do not affect board-level interconnection compatibility when the core parameters remain constant.

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity 5-146258-8 (Primary Part)

The 5-146258-8 is the primary specification with Active product status and RoHS Compliant certification. This part features tin contact finish on mating surfaces with 100.0µin thickness and copper alloy contact material. The insulation material is Liquid Crystal Polymer (LCP) with 0.090" height. Operating temperature range extends from -65°C to 105°C. Moisture Sensitivity Level is 1 (Unlimited). This configuration is suitable for standard through-hole applications requiring tin-plated contacts.

TE Connectivity 9-146257-0-08 (Substitute)

The 9-146257-0-08 maintains AMPMODU Mod II series compatibility with Active product status and ROHS3 Compliant certification. This part substitutes gold contact finish on mating surfaces (30.0µin thickness) while retaining copper alloy contact material and LCP insulation. Contact post length increases to 0.120" (3.05mm) compared to 0.090" on the primary part. Operating temperature range remains -65°C to 105°C. This configuration is suitable for applications requiring enhanced corrosion resistance through gold plating.

Sullins Connector Solutions PBC08DAAN (Substitute)

The PBC08DAAN is an alternative from a different manufacturer with Active product status and ROHS3 Compliant certification. This part features gold contact finish on mating surfaces (10.0µin thickness) with phosphor bronze contact material and PBT insulation. Contact post length is 0.120" (3.05mm) and insulation height is 0.100" (2.54mm). Operating temperature range extends to -65°C to 125°C, providing higher thermal capability. Moisture Sensitivity Level is Not Applicable. This configuration is suitable for applications requiring extended temperature operation and alternative material composition.

Frequently Asked Questions (FAQ)

Q: Can the 9-146257-0-08 directly replace the 5-146258-8 in existing designs?

A: The 9-146257-0-08 maintains all core electrical and mechanical compatibility parameters including 16-position, 2-row configuration, 0.100" pitch, through-hole mounting, and 3A current rating. The primary differences are contact finish composition (gold versus tin) and contact post length (0.120" versus 0.090"). These variations do not affect board-level interconnection compatibility. Design verification is required only if the application has specific contact finish or post length constraints.

Q: What are the implications of using PBC08DAAN with its higher operating temperature range?

A: The PBC08DAAN operates to -65°C to 125°C compared to -65°C to 105°C for the 5-146258-8. This extended upper temperature capability does not create incompatibility when used in applications operating within the 5-146258-8 temperature range. The PBC08DAAN is suitable for applications requiring operation above 105°C. All other core parameters remain equivalent.

Q: How do contact finish differences affect connector performance?

A: The 5-146258-8 uses tin contact finish (100.0µin thickness), while the 9-146257-0-08 and PBC08DAAN use gold contact finish (30.0µin and 10.0µin respectively). Gold provides enhanced corrosion resistance and lower contact resistance over extended service life. Tin provides cost efficiency for standard applications. Both finishes are compatible with standard PCB assembly and soldering processes. Selection depends on application environment and performance requirements.

Q: Are there differences in insulation material between these parts?

A: The 5-146258-8 and 9-146257-0-08 use Liquid Crystal Polymer (LCP) insulation, while the PBC08DAAN uses Polybutylene Terephthalate (PBT). Both materials meet UL94 V-0 flammability requirements. LCP provides superior dimensional stability and lower moisture absorption. PBT offers cost efficiency and established performance in standard applications. Material selection does not affect electrical compatibility when core parameters remain constant.

Q: What is the significance of Moisture Sensitivity Level differences?

A: The 5-146258-8 and 9-146257-0-08 have Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling. The PBC08DAAN has Moisture Sensitivity Level Not Applicable, indicating the component does not require moisture-controlled storage. This difference does not affect functional compatibility but may influence procurement and storage procedures.

Q: Can these parts be mixed in the same assembly?

A: All three parts maintain identical 16-position, 2-row configuration with 0.100" pitch and through-hole mounting. They can be used in the same assembly when application requirements permit variation in contact finish, insulation material, and operating temperature range. Design documentation should specify which part number is acceptable for each connector location to ensure consistency with performance requirements.
