Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SL-112-T-31 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)
• Contact finish and thickness (Gold, 30.0µin)
• Insulation material (Liquid Crystal Polymer)
• Operating temperature range (-55°C ~ 125°C)
• Series designation (SL)
• Compliance certifications (ROHS3)

Parts meeting all these criteria are classified as direct substitutes within the SL series connector family.

Parameter Comparison

Engineering Selection Recommendations

Both the SL-112-T-31 and SL-112-T-39 maintain active product status with identical electrical and mechanical specifications. Selection between these parts is based on inventory availability and supply chain considerations. The SL-112-T-39 carries additional REACH Affected designation in its compliance profile. Both parts are ROHS3 compliant and carry MSL 1 rating, indicating no moisture sensitivity restrictions during storage and handling. The identical operating temperature range, contact materials, and termination specifications ensure functional equivalence in board-to-board connector applications.

Frequently Asked Questions (FAQ)

Q: Are SL-112-T-31 and SL-112-T-39 electrically interchangeable?

A: Yes. Both connectors maintain identical electrical specifications including contact material (Beryllium Copper), contact finish (Gold, 30.0µin thickness), and operating temperature range (-55°C ~ 125°C).

Q: What are the mechanical compatibility requirements?

A: Both parts share identical mechanical specifications: 12 positions, 0.100" (2.54mm) pitch, single-row configuration, through-hole mounting, and 0.050" (1.27mm) insulation height. They are mechanically interchangeable in PCB layouts designed for either part number.

Q: Are there compliance differences between these parts?

A: Both parts are ROHS3 compliant with EAR99 ECCN classification and HTSUS code 8536.69.4040. The SL-112-T-39 carries REACH Affected status, which may impact supply chain documentation in certain regulatory jurisdictions.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions. Standard handling and storage practices apply without special environmental controls.

Q: Can these connectors be used interchangeably in existing designs?

A: Yes, within the constraints of the specified electrical and mechanical parameters. PCB footprints, mating connector specifications, and application requirements must remain consistent with the original design parameters.
