Substitute Part Grouping Explanation

Substitution compatibility for the MMS-131-01-L-SH is determined by strict alignment of the following critical parameters:

  • Connector Type & Contact Configuration: Receptacle with female socket contacts
  • Position Count & Pitch: 31 positions at 0.079" (2.00mm) mating pitch
  • Mounting & Termination: Through-hole, right-angle orientation with solder termination
  • Electrical Performance: 3.9A per contact current rating
  • Environmental Compliance: RoHS3 compliance and operating temperature range of -55°C to 125°C
  • Contact Materials & Finish: Gold-plated mating contacts with phosphor bronze base material

Only components matching all these parameters across connector architecture, electrical specifications, and compliance certifications qualify as direct substitutes.

Engineering Selection Recommendations

The MMS-131-01-L-SH maintains active product status with full RoHS3 compliance and REACH unaffected designation. These certifications ensure regulatory alignment for applications in regulated industries and markets with environmental compliance requirements.

When selecting this connector or evaluating alternatives, prioritize components with identical product status classification and matching compliance certifications. Active status products ensure ongoing manufacturer support, availability, and process consistency. RoHS3 compliance is mandatory for applications subject to European Union directives and equivalent international standards.

The connector's Moisture Sensitivity Level (MSL) rating of 1 (Unlimited) indicates minimal moisture absorption risk, reducing handling and storage constraints during procurement and assembly operations.

Frequently Asked Questions (FAQ)

Q: What defines a direct substitute for the MMS-131-01-L-SH?

A: A direct substitute must match all critical parameters: 31-position receptacle configuration, 2.00mm mating pitch, through-hole right-angle mounting, solder termination, 3.9A per contact current rating, gold-plated mating contacts, and RoHS3 compliance. Deviations in any of these parameters result in incompatibility with the original design specification.

Q: Can connectors with different position counts be used as substitutes?

A: No. The 31-position count is a fixed design requirement. Connectors with alternative position counts (such as 20, 25, or 40 positions) are not compatible and require complete circuit redesign.

Q: Are there packaging format considerations for this connector?

A: The MMS-131-01-L-SH is supplied in tube packaging. Substitute parts must maintain identical packaging specifications to ensure compatibility with automated assembly equipment and inventory management systems.

Q: What is the significance of the gold contact finish specification?

A: The gold-plated mating contact finish provides corrosion resistance and ensures reliable electrical contact over the connector's operational lifetime. Substitutes must maintain this finish specification to preserve signal integrity and contact reliability.

Q: Does the RoHS3 compliance status affect substitute selection?

A: Yes. RoHS3 compliance is a mandatory requirement for applications in regulated markets. All substitute components must carry identical RoHS3 certification to maintain regulatory compliance and avoid supply chain disruptions.
