Selection of this part ensures compliance with established design standards and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: What determines if a part can substitute for the SL-131-G-10?

A: A substitute must match all critical parameters: 31-position receptacle configuration, 0.100" (2.54mm) pitch, through-hole solder termination, gold-plated beryllium copper contacts, and Liquid Crystal Polymer insulation. Deviations in any of these parameters result in incompatibility.

Q: Are there alternative part numbers from other manufacturers listed as substitutes?

A: Based on the provided data, no alternative manufacturer part numbers are listed as substitutes for the SL-131-G-10. The part is identified as its own equivalent.

Q: What is the significance of the MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. This connector can be stored and handled under standard conditions without special desiccant packaging or baking procedures.

Q: Does the gold plating thickness affect substitution eligibility?

A: Yes. The mating surface gold finish must be 30.0µin (0.76µm) and the post finish must be 10.0µin (0.25µm). Variations in plating thickness outside these specifications indicate a different part variant and are not acceptable substitutes.

Q: What is the operational temperature range for this connector?

A: The SL-131-G-10 operates reliably between -55°C and 125°C, making it suitable for industrial and commercial applications requiring extended temperature performance.
