Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MMS-111-02-L-SH is determined by strict alignment across the following critical parameters:

• Connector Type & Contact Configuration: Must be a receptacle with female socket contacts
• Position Count & Pitch: Exactly 11 positions at 0.079" (2.00mm) mating pitch
• Mounting & Termination: Surface mount, right-angle orientation with solder termination
• Electrical Performance: Minimum 3.9A per contact current rating
• Environmental Compliance: RoHS3 compliance and MSL Level 1 rating required
• Material & Contact Finish: Liquid Crystal Polymer insulation with gold-plated mating contacts

Based on the provided input data, the MMS-111-02-L-SH is listed as its own substitute, indicating no alternative parts from different manufacturers have been specified for comparison.

Engineering Selection Recommendations

The MMS-111-02-L-SH maintains active product status with full regulatory compliance across RoHS3 and REACH standards. The part carries an ECCN classification of EAR99 and HTSUS code 8536.69.4040. With 857 pieces currently in stock as new original inventory, the part is readily available for immediate procurement. The MSL Level 1 rating eliminates moisture sensitivity concerns during storage and handling. Selection of this connector is appropriate for applications requiring reliable surface-mount rectangular connectivity with the specified electrical and environmental performance characteristics.

Frequently Asked Questions (FAQ)

Q: What defines a valid substitute for the MMS-111-02-L-SH? A: A valid substitute must match the 11-position receptacle configuration, 0.079" (2.00mm) pitch, surface-mount right-angle mounting, 3.9A per contact current rating, and maintain RoHS3 compliance with MSL Level 1 rating.

Q: Can connectors with different pitch values be used as substitutes? A: No. The 0.079" (2.00mm) mating pitch is a critical parameter. Connectors with different pitch values are not compatible and cannot be substituted.

Q: Are there position count variations that can be substituted? A: No. The 11-position configuration is fixed. Connectors with different position counts do not meet substitution criteria.

Q: What is the significance of the gold contact finish specification? A: The gold-plated mating contact finish is specified for corrosion resistance and reliable electrical contact. Substitutes must maintain this finish specification.

Q: Does the MSL Level 1 rating affect storage requirements? A: No. MSL Level 1 indicates unlimited shelf life without moisture sensitivity concerns, allowing standard storage conditions without desiccant packaging requirements.

Q: Is the surface-mount right-angle orientation interchangeable with other mounting styles? A: No. The right-angle surface-mount configuration is application-specific. Alternative mounting styles are not compatible substitutes.
