• Number of Positions: 22
• Pitch - Mating: 0.100" (2.54mm)
• Mounting Type: Through Hole
• Termination: Solder
• Contact Finish - Mating: Gold
• Operating Temperature Range: -55°C ~ 125°C
• Insulation Material: Liquid Crystal Polymer (LCP)
• Contact Material: Beryllium Copper
• Series: SL

The SL-122-G-39 meets all substitution criteria and is classified as a direct equivalent within the SL series rectangular connector family.

Parameter Comparison

Engineering Selection Recommendations

Both the SL-122-G-31 and SL-122-G-39 are Active status products manufactured by Samtec Inc. and maintain identical electrical and mechanical specifications. Both parts are ROHS3 compliant and carry MSL rating of 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling. Selection between these parts may be based on inventory availability, lead time, or supply chain requirements, as they are functionally interchangeable within the SL series rectangular connector family.

Frequently Asked Questions (FAQ)

Q: Can SL-122-G-39 be used as a direct replacement for SL-122-G-31?

A: Yes. Both parts share identical electrical and mechanical parameters, including connector type, contact configuration, pitch, mounting method, termination, contact finish, operating temperature range, and insulation material. They are functionally equivalent.

Q: Are there any differences in compliance or certification between these parts?

A: No. Both parts are ROHS3 compliant, carry identical ECCN (EAR99) and HTSUS classifications, and share the same MSL rating of 1 (Unlimited).

Q: What determines substitution eligibility for rectangular connectors in the SL series?

A: Substitution is based on equivalence across connector type, contact type, number of positions, mating pitch, mounting type, termination method, contact finish, operating temperature range, insulation material, and contact material. Deviation in any of these parameters disqualifies a part as a direct substitute.

Q: Are there inventory differences between these parts?

A: The SL-122-G-31 has 1088 pcs in stock, while the SL-122-G-39 has 1243 pcs in stock. Both are available as new original components in bulk packaging.
