Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SL-122-T-32 is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (22)
• Mating pitch (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination type (Solder)
• Contact finish material (Gold)
• Operating temperature range (-55°C ~ 125°C)
• Insulation material (Liquid Crystal Polymer)
• Contact material (Beryllium Copper)
• RoHS compliance status (ROHS3 Compliant)

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

Parameter Comparison

Engineering Selection Recommendations

Both the SL-122-T-32 and SL-122-G-39 are Active product status connectors manufactured by Samtec Inc. and maintain full ROHS3 compliance. The SL-122-G-39 carries additional REACH Affected designation. Selection between these parts should be based on inventory availability and application-specific compliance requirements. Both connectors are suitable for identical electrical and mechanical applications within the specified operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can the SL-122-G-39 be used as a direct replacement for the SL-122-T-32?

A: Yes. Both connectors share identical electrical and mechanical specifications across all critical parameters including connector type, contact configuration, pitch, mounting method, and operating temperature range.

Q: What are the key differences between these two part numbers?

A: The primary difference is the Contact Finish - Post specification. The SL-122-T-32 does not specify a post finish, while the SL-122-G-39 specifies gold plating at 10.0µin (0.25µm) on the post. Additionally, the SL-122-G-39 carries REACH Affected status.

Q: Are there any compatibility concerns when substituting between these parts?

A: No compatibility concerns exist. Both connectors are designed for the same board-to-board applications with identical mating pitch, contact type, and mounting configuration.

Q: What is the significance of the MSL rating for these connectors?

A: Both connectors carry MSL 1 (Unlimited), indicating no moisture sensitivity limitations during storage or handling.

Q: Do both parts meet the same regulatory standards?

A: Both parts are ROHS3 compliant and classified under ECCN EAR99. The SL-122-G-39 additionally carries REACH Affected designation.
