Key Parameters

Substitute Part Grouping Explanation

Substitution within the SOLC-120 series is determined by strict equivalence of the following critical parameters:

• Number of positions: 80
• Pitch - mating: 0.050" (1.27mm)
• Number of rows: 4
• Row spacing - mating: 0.050" (1.27mm)
• Connector type: Receptacle
• Contact type: Forked
• Mounting type: Surface Mount
• Termination: Solder
• Current rating: 2.4A per Contact
• Operating temperature range: -55°C ~ 125°C
• Contact finish: Gold
• Material flammability rating: UL94 V-0

The SOLC-120-02-F-Q-LC variant maintains all critical electrical and mechanical parameters while incorporating a board lock feature. Both parts are manufactured by Samtec Inc. within the same FOURRAY™ SOLC series and share identical contact configurations, pitch specifications, and performance ratings.

Parameter Comparison

Engineering Selection Recommendations

Both SOLC-120-02-F-Q and SOLC-120-02-F-Q-LC are active products manufactured by Samtec Inc. and maintain full compliance with ROHS3 and UL94 V-0 flammability standards. Selection between these parts depends on mechanical design requirements:

The SOLC-120-02-F-Q provides standard board-to-board connectivity without additional mechanical retention features. The SOLC-120-02-F-Q-LC incorporates a board lock mechanism while maintaining identical electrical performance and contact specifications. Both parts are suitable for applications requiring 80-position, 0.050" pitch surface mount receptacle connectors with 2.4A per contact current capacity across the -55°C to 125°C operating range.

Frequently Asked Questions (FAQ)

Q: Are SOLC-120-02-F-Q and SOLC-120-02-F-Q-LC electrically interchangeable?

A: Yes. Both parts maintain identical electrical specifications including 80 positions, 0.050" mating pitch, 4-row configuration, 2.4A per contact current rating, and gold contact finish. The difference is mechanical, with the -LC variant including a board lock feature.

Q: What is the primary difference between these two connectors?

A: The SOLC-120-02-F-Q-LC includes a board lock feature not present in the standard SOLC-120-02-F-Q. All other electrical and mechanical parameters remain identical.

Q: Can I use SOLC-120-02-F-Q-LC as a direct replacement for SOLC-120-02-F-Q?

A: Direct replacement is possible from an electrical standpoint. However, the board lock feature on the -LC variant may require design modifications to the mating connector or PCB layout. Verify mechanical compatibility with your mating connector before substitution.

Q: What are the critical parameters for substitution within the SOLC-120 series?

A: Critical parameters include 80-position count, 0.050" mating pitch, 4-row configuration with 0.050" row spacing, surface mount termination, forked contact type, gold contact finish, and 2.4A per contact current rating.

Q: Are both parts RoHS compliant?

A: Yes. Both SOLC-120-02-F-Q and SOLC-120-02-F-Q-LC are ROHS3 compliant with UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity level.
