SL-112-T-30 Equivalent & Substitute Parts

Part Overview

The SL-112-T-30 is a 12-position receptacle connector manufactured by Samtec Inc., designed for board-to-board applications with 0.100" (2.54mm) pitch through-hole mounting. This connector features gold-plated circular beryllium copper contacts with push-pull fastening and operates across -55°C to 125°C. The part is currently active in production with ROHS3 compliance and MSL 1 rating. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector series, ensuring functional interchangeability in circuit designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SL-112-T-30 is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (12)
• Pitch specification (0.100" / 2.54mm)
• Mounting method (Through Hole)
• Termination type (Solder)
• Fastening mechanism (Push-Pull)
• Contact finish and thickness (Gold, 30.0µin)
• Operating temperature range (-55°C ~ 125°C)
• Insulation material (Liquid Crystal Polymer)
• Contact material (Beryllium Copper)

The SL-112-T-39 meets all these criteria, maintaining identical electrical and mechanical specifications while belonging to the same SL series base product family (SL-112).

Parameter Comparison

Engineering Selection Recommendations

Both the SL-112-T-30 and SL-112-T-39 are active production parts with identical compliance certifications. The SL-112-T-39 carries additional REACH Affected status documentation. Selection between these parts should be based on inventory availability and supply chain requirements, as all electrical and mechanical parameters are equivalent. The SL-112-T-39 currently maintains higher inventory levels (1826 pcs vs. 951 pcs), which may influence procurement decisions for high-volume applications.

Frequently Asked Questions (FAQ)

Q: Are the SL-112-T-30 and SL-112-T-39 electrically interchangeable?

A: Yes. Both connectors maintain identical contact materials (beryllium copper), finish specifications (gold, 30.0µin), and operating temperature ranges (-55°C ~ 125°C). They are electrically equivalent for board-to-board applications.

Q: What determines substitution eligibility for this connector family?

A: Substitution is valid when the following parameters match: connector type (receptacle), contact type (female socket), position count (12), pitch (0.100"), mounting method (through hole), termination (solder), fastening (push-pull), contact finish (gold, 30.0µin), operating temperature (-55°C ~ 125°C), insulation material (LCP), and contact material (beryllium copper).

Q: Can I use the SL-112-T-39 as a direct replacement in existing designs?

A: Yes. The SL-112-T-39 is a direct substitute with no design modifications required. All mechanical dimensions, electrical characteristics, and compliance certifications are identical to the SL-112-T-30.

Q: What is the difference between the -T-30 and -T-39 designations?

A: The suffix designations indicate internal Samtec product variants within the SL-112 base series. Both variants maintain equivalent specifications for the parameters provided in this reference.

Q: Are both parts RoHS compliant?

A: Yes. Both the SL-112-T-30 and SL-112-T-39 are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating.
