Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76314-250LF is determined by the following critical parameters:

• Connector Type & Positions: All substitutes must be 100-position receptacles with identical mating pitch (0.100") and row configuration (2 rows, 0.100" spacing)
• Mounting & Termination: Through-hole solder termination is mandatory for all substitutes
• Fastening & Insulation Height: Push-pull fastening and 0.335" (8.51mm) insulation height must be maintained
• Contact Material & Finish: Substitutes may vary in contact material (brass vs. phosphor bronze) and post finish (tin vs. gold), provided the mating contact finish remains gold
• Compliance: All substitutes must maintain UL94 V-0 flammability rating and RoHS compliance

The Samtec SSQ and SSW series parts listed below meet these core requirements while offering variations in contact geometry (forked vs. square), contact material composition, and thermal operating ranges.

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain active product status and comply with UL94 V-0 flammability and RoHS requirements. Selection among substitutes depends on specific application constraints:

For applications requiring extended thermal range: SSQ-150-01-G-D, SSQ-150-21-S-D, SSW-150-01-G-D, SSW-150-01-S-D, SSW-150-02-G-D, SSW-150-02-S-D, and SSW-150-21-S-D all support -55°C to 125°C operation. SSW-150-01-T-D operates to 105°C maximum.

For applications with specified current requirements: SSW series parts (SSW-150-01-G-D, SSW-150-01-S-D, SSW-150-01-T-D, SSW-150-02-G-D, SSW-150-02-S-D, SSW-150-21-S-D) provide 4.7A per contact rating. SSQ series parts do not specify current rating.

For contact post length variations: Standard post length (0.104") is available in SSQ-150-01-G-D, SSQ-150-21-S-D, SSW-150-01-G-D, SSW-150-01-S-D, SSW-150-01-T-D, and SSW-150-21-S-D. Extended post length (0.194") is available in SSW-150-02-G-D and SSW-150-02-S-D.

For post finish requirements: Gold post finish is available in SSQ-150-01-G-D, SSW-150-01-G-D, and SSW-150-02-G-D. Tin post finish is available in SSQ-150-21-S-D, SSW-150-01-S-D, SSW-150-01-T-D, SSW-150-02-S-D, and SSW-150-21-S-D.

Frequently Asked Questions (FAQ)

Q: Can SSW-150-01-T-D be used as a direct substitute for 76314-250LF? A: SSW-150-01-T-D is mechanically and electrically compatible but features tin mating contact finish instead of gold, and operates to 105°C maximum instead of an unspecified range. Use only if application requirements permit tin mating contacts and do not exceed 105°C operating temperature.

Q: What is the difference between SSQ and SSW series substitutes? A: Both series meet core substitution criteria. SSW series parts specify 4.7A per contact current rating, while SSQ series parts do not. Both use forked contact geometry and Liquid Crystal Polymer insulation material.

Q: Are contact post length variations interchangeable? A: Contact post length affects board-to-board stacking height and PCB pad engagement depth. Standard length (0.104") and extended length (0.194") are not interchangeable. Verify PCB design requirements before selecting post length variant.

Q: Do all substitutes maintain the same insulation material? A: No. The 76314-250LF uses thermoplastic polyester with glass filler. All Samtec substitutes use Liquid Crystal Polymer (LCP) insulation. LCP provides superior thermal and chemical resistance but may require design verification for specific applications.

Q: What is the significance of contact finish thickness variations? A: Contact finish thickness affects durability and wear resistance. Mating contact finish thickness ranges from 20.0µin to 39.4µin across substitutes. Post finish thickness varies from 3.00µin to 78.7µin. Thicker finishes provide extended contact life in high-cycle mating applications.

Q: Are all substitutes available in equivalent packaging quantities? A: The 76314-250LF is supplied in tube packaging with 1094 units in stock. All Samtec substitutes are supplied in bulk packaging with varying inventory levels (741 to 3755 units). Confirm packaging and quantity requirements with supplier.
