Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76314-123LF is determined by the following core parameters that must remain constant:

• 46 positions in a 2-row configuration
• 0.100" (2.54mm) mating pitch and row spacing
• Through-hole solder termination
• Push-pull fastening mechanism
• 0.335" (8.51mm) insulation height
• UL94 V-0 flammability rating

Acceptable variations include:

• Contact type (female socket to forked contact)
• Insulation material (thermoplastic polyester to liquid crystal polymer)
• Contact finish composition (brass to phosphor bronze)
• Contact finish thickness specifications
• Contact post length (within mechanical clearance limits)
• Contact finish type (gold or tin on mating surface)

The substitute parts listed below maintain these core parameters while offering alternative specifications for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts listed maintain active product status and meet UL94 V-0 flammability requirements. Selection between the 76314-123LF and substitute options depends on specific application constraints:

PPPC232LFBN-RC (Sullins Connector Solutions): Header connector variant with female socket contacts. Suitable for applications requiring header-style mating. Operating temperature range -40°C to 105°C. Current rating 3A per contact at 250V. RoHS3 compliant.

SSQ-123-04-G-D and SSQ-123-04-G-D (Samtec Inc., SSQ Series): Forked contact receptacles with extended post length (0.584"). Operating temperature -55°C to 125°C. Voltage rating 465VAC / 655VDC. Liquid crystal polymer insulation. RoHS3 compliant. Suitable for applications requiring higher temperature operation and extended contact engagement.

SSQ-123-22-G-D (Samtec Inc., SSQ Series): Forked contact receptacle with moderate post length (0.194"). Operating temperature -55°C to 125°C. Voltage rating 465VAC / 655VDC. RoHS3 compliant.

SSQ-123-23-F-D (Samtec Inc., SSQ Series): Forked contact receptacle with tin post finish and 0.394" post length. Operating temperature -55°C to 125°C. Voltage rating 465VAC / 655VDC. RoHS3 compliant.

SSW-123-01-F-D (Samtec Inc., SSW Series): Forked contact receptacle with shortest post length (0.104"). Current rating 4.7A per contact. Operating temperature -55°C to 125°C. Tin post finish. RoHS3 compliant. Suitable for compact PCB designs.

SSW-123-04-G-D (Samtec Inc., SSW Series): Forked contact receptacle with extended post length (0.584"). Current rating 4.7A per contact. Operating temperature -55°C to 125°C. Gold post finish. RoHS3 compliant.

SSW-123-06-T-D (Samtec Inc., SSW Series): Tin mating finish receptacle with moderate post length (0.124"). Current rating 4.7A per contact. Operating temperature -55°C to 105°C. RoHS3 compliant. Suitable for cost-optimized applications where gold mating finish is not required.

Frequently Asked Questions (FAQ)

Q: Can I substitute the 76314-123LF with a header connector like PPPC232LFBN-RC?

A: Yes, if your application permits header-style mating. The PPPC232LFBN-RC maintains the same 46-position, 0.100" pitch configuration and through-hole solder termination. The primary difference is connector type (header vs. receptacle), which affects mating interface design.

Q: What is the difference between forked and socket contacts?

A: The 76314-123LF uses female socket contacts. Samtec SSQ and SSW series substitutes use forked contacts. Both contact types are compatible with standard 0.100" pitch pin headers. Forked contacts provide dual-point contact engagement, while socket contacts provide single-point engagement.

Q: Which substitute offers the highest operating temperature range?

A: SSQ-123-04-G-D, SSQ-123-22-G-D, SSQ-123-23-F-D, and SSW-123-01-F-D, and SSW-123-04-G-D all support -55°C to 125°C operation. The 76314-123LF and PPPC232LFBN-RC do not specify operating temperature. SSW-123-06-T-D supports -55°C to 105°C.

Q: What is the difference between gold and tin mating finishes?

A: The 76314-123LF and most substitutes feature gold mating finish for superior corrosion resistance and contact reliability. SSW-123-06-T-D features tin mating finish, suitable for applications where gold plating is not required and cost optimization is prioritized.

Q: How do post length variations affect compatibility?

A: Post length determines the depth of contact engagement with mating pins. Variations from 0.104" to 0.584" accommodate different PCB thicknesses and mating depths. Selection depends on your specific PCB thickness and connector stack-up requirements. Shorter posts (0.104" to 0.194") suit thin PCBs; longer posts (0.394" to 0.584") accommodate thicker assemblies or extended engagement.

Q: Are all substitutes RoHS compliant?

A: Yes. The 76314-123LF is RoHS Compliant. All listed substitutes are ROHS3 Compliant, meeting current regulatory requirements.

Q: What current ratings should I consider?

A: The 76314-123LF does not specify current rating. PPPC232LFBN-RC is rated 3A per contact. Samtec SSW series parts (SSW-123-01-F-D, SSW-123-04-G-D, SSW-123-06-T-D) are rated 4.7A per contact. SSQ series parts do not specify current rating. Select based on your application's current requirements.
