Key Parameters

Substitute Part Grouping Explanation

Substitution of the 76385-310 is determined by strict equivalence across the following critical parameters:

• Connector type classification (Header)
• Contact type and gender (Male Pin)
• Position count and row configuration (20 positions, 2 rows)
• Mating pitch and row spacing (0.100" / 2.54mm)
• Mounting methodology (Through Hole)
• Shrouding design (Shrouded - 2 Wall)
• Contact geometry (Square shape)
• Insulation material composition (Thermoplastic, Glass Filled)
• Flammability compliance (UL94 V-0)

The 76385-310LF meets all these criteria and qualifies as a direct functional substitute. Differences in secondary parameters such as contact finish composition, insulation color, and compliance status do not affect mechanical or electrical interchangeability in standard applications.

Parameter Comparison

Engineering Selection Recommendations

The 76385-310LF is the direct functional equivalent for the obsolete 76385-310. Selection of the 76385-310LF is supported by the following factors:

Product Status: The 76385-310LF maintains active product status with current manufacturing availability, whereas the 76385-310 is classified as obsolete. This ensures supply chain continuity and long-term component availability.

Compliance Posture: The 76385-310LF achieves RoHS compliance, meeting current regulatory requirements for new designs and manufacturing processes. The original 76385-310 is RoHS non-compliant, which may present restrictions in certain applications and jurisdictions.

Contact Finish Specification: The 76385-310LF incorporates GXT™ gold plating technology on mating contacts, providing enhanced corrosion resistance compared to standard gold plating. The post finish transitions from tin-lead to tin, aligning with lead-free manufacturing standards.

Mechanical and Electrical Equivalence: All critical dimensional, mechanical, and electrical parameters remain identical between the two parts, ensuring direct interchangeability in existing PCB layouts and connector mating applications.

Frequently Asked Questions (FAQ)

Q: Can the 76385-310LF be used as a direct replacement for the 76385-310 in existing designs?

A: Yes. The 76385-310LF is mechanically and electrically equivalent to the 76385-310. All critical parameters including pitch, position count, row configuration, contact dimensions, and shrouding design are identical. PCB footprints and mating connector compatibility remain unchanged.

Q: What is the significance of the "LF" designation in the 76385-310LF part number?

A: The "LF" suffix indicates lead-free compliance. This designation reflects the transition from tin-lead solder finish on the post contacts to pure tin, aligning with RoHS and lead-free manufacturing standards.

Q: Are there any performance differences between the gold plating on the 76385-310 and the GXT™ plating on the 76385-310LF?

A: Both maintain the same mating contact finish thickness of 30.0µin (0.76µm). The GXT™ technology on the 76385-310LF provides enhanced corrosion resistance characteristics. Both finishes meet the same electrical and mechanical performance requirements for standard applications.

Q: What packaging format is available for the 76385-310LF?

A: The 76385-310LF is supplied in tube packaging, with 1065 pieces per tube available in new original stock.

Q: Is the 76385-310 still available for purchase?

A: The 76385-310 is classified as obsolete. Current inventory of 895 pieces remains available, but no new production is scheduled. The 76385-310LF is the recommended active alternative with ongoing manufacturing support.

Q: Do both parts meet the same flammability and environmental standards?

A: Yes. Both the 76385-310 and 76385-310LF meet UL94 V-0 material flammability rating and carry MSL 1 (Unlimited) moisture sensitivity classification. Both are classified under ECCN EAR99 and HTSUS 8536.69.4040.
