Engineering Selection Recommendations

All identified substitute parts maintain active production status and comply with UL94 V-0 flammability requirements, ensuring suitability for applications requiring flame-resistant materials. The following selection criteria apply based on provided specifications:

PBC08DFAN (Sullins): Direct functional equivalent with identical mating contact length (0.318"), minimal post length variation (0.120" versus 0.125"), and gold-plated mating contacts matching the main part. Offers extended operating temperature range to 125°C and ROHS3 compliance. Suitable for applications requiring phosphor bronze contact material and PBT insulation.

PBC08DFBN (Sullins): Functionally equivalent with extended post length (0.220") for applications requiring deeper PCB penetration. Maintains gold-plated mating contacts and 3A current rating. Extended operating temperature range to 125°C and ROHS3 compliance. Post length variation requires mechanical clearance verification.

PBC08DFEN (Sullins): Functionally equivalent with significantly extended post length (0.520") for applications requiring maximum PCB penetration depth. Maintains gold-plated mating contacts and 3A current rating. Extended operating temperature range to 125°C and ROHS3 compliance. Post length variation requires mechanical clearance verification.

PEC08DFAN (Sullins): Functionally equivalent with tin-plated mating contacts (100.0µin thickness) instead of gold plating. Identical post length to PBC08DFAN (0.120"). Extended operating temperature range to 125°C and ROHS3 compliance. Suitable for applications where tin contact finish is acceptable.

TSW-108-14-T-D (Samtec): Functionally equivalent with tin-plated mating contacts and minimal post length (0.110"). Operates within -55°C to 105°C range, matching the lower temperature limit of the main part. ROHS3 compliant. Current rating not specified in provided data. Suitable for applications where tin contact finish and compact post length are required.

Frequently Asked Questions (FAQ)

Q: Can PBC08DFAN be used as a direct replacement for 5-146252-8?

A: Yes. PBC08DFAN maintains all critical electrical and mechanical parameters: 16 positions, 2 rows, 0.100" pitch, male pins, through-hole mounting, solder termination, push-pull fastening, 3A current rating, and UL94 V-0 flammability rating. Minor variations in contact material (phosphor bronze versus copper alloy), insulation material (PBT versus LCP), and post length (0.120" versus 0.125") do not affect functional interchangeability. Extended operating temperature range (-65°C to 125°C) provides additional thermal margin.

Q: What is the difference between the Sullins PBC08 series parts?

A: The PBC08DFAN, PBC08DFBN, and PBC08DFEN parts differ primarily in post length. PBC08DFAN has a 0.120" post, PBC08DFBN has a 0.220" post, and PBC08DFEN has a 0.520" post. All three maintain identical mating contact length (0.318"), pitch (0.100"), and electrical ratings (3A, -65°C to 125°C). Selection depends on required PCB penetration depth and available mechanical clearance.

Q: Why does PEC08DFAN have tin-plated mating contacts instead of gold?

A: PEC08DFAN is specified with tin-plated mating contacts (100.0µin thickness) as a cost-effective alternative to gold plating. Tin provides adequate corrosion resistance and electrical conductivity for standard applications. Selection between gold-plated (PBC08 series) and tin-plated (PEC08DFAN) contacts depends on application requirements for contact resistance, corrosion resistance, and environmental exposure.

Q: Is TSW-108-14-T-D compatible with the 5-146252-8 in all applications?

A: TSW-108-14-T-D maintains functional equivalence in connector geometry, pitch, position count, and fastening type. However, the operating temperature range (-55°C to 105°C) has a higher lower limit than the main part (-65°C). Applications requiring operation below -55°C require verification of TSW-108-14-T-D suitability. Current rating is not specified for TSW-108-14-T-D; applications requiring confirmed 3A rating should reference Samtec technical documentation.

Q: What are the mechanical clearance considerations when substituting parts with different post lengths?

A: Post length variations affect PCB penetration depth and solder joint formation. PBC08DFAN and PEC08DFAN (0.120" posts) provide minimal penetration similar to the main part (0.125"). PBC08DFBN (0.220" post) and PBC08DFEN (0.520" post) require deeper PCB holes and provide extended mechanical engagement. TSW-108-14-T-D (0.110" post) provides the shortest penetration. PCB design must accommodate the selected post length to ensure adequate solder joint quality and mechanical stability.

Q: Are all substitute parts RoHS compliant?

A: Yes. The main part 5-146252-8 is RoHS Compliant. All identified substitute parts (PBC08DFAN, PBC08DFBN, PBC08DFEN, PEC08DFAN, and TSW-108-14-T-D) are ROHS3 Compliant, meeting current RoHS Directive requirements. All parts are suitable for applications requiring RoHS compliance.

Q: What is the difference between LCP and PBT insulation materials?

A: The main part uses Liquid Crystal Polymer (LCP) insulation, while all substitute parts use Polybutylene Terephthalate (PBT). Both materials meet UL94 V-0 flammability requirements. LCP offers superior dimensional stability and lower moisture absorption. PBT provides cost-effective performance with adequate mechanical and thermal properties. Material selection depends on application requirements for dimensional tolerance, moisture resistance, and thermal cycling performance.
