Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MMS-105-02-LM-SH are identified based on strict electrical and mechanical parameter equivalence within the MMS series. The substitution criteria are:

• Identical connector type (Receptacle) and contact type (Female Socket)
• Matching pitch specification (0.079" / 2.00mm)
• Identical number of positions (5)
• Equivalent mounting configuration (Surface Mount, Right Angle)
• Matching termination method (Solder)
• Identical contact finish specification (Gold plating at 10.0µin / 0.25µm)
• Equivalent current rating (3.9A per contact)
• Matching operating temperature range (-55°C ~ 125°C)
• Identical insulation material (Liquid Crystal Polymer)
• Equivalent contact material (Phosphor Bronze)
• Matching compliance certifications (ROHS3, MSL 1)

Parameter Comparison

Engineering Selection Recommendations

Both the MMS-105-02-LM-SH and MMS-105-02-L-SH maintain active product status with full ROHS3 compliance and MSL 1 rating. The parts are electrically and mechanically equivalent across all specified parameters. Selection between these parts may be based on inventory availability, lead time, or packaging considerations, as both parts are supplied in tube packaging by Samtec Inc. and are suitable for direct substitution in applications requiring 5-position, 2.00mm pitch surface mount receptacle connectors with gold-plated contacts and 3.9A current capacity.

Frequently Asked Questions (FAQ)

Q: Are MMS-105-02-LM-SH and MMS-105-02-L-SH fully interchangeable?

A: Yes. Both parts are electrically and mechanically equivalent. They share identical specifications for pitch, position count, contact finish, current rating, operating temperature, and compliance certifications. Direct substitution is supported without design modification.

Q: What determines substitution eligibility for MMS series receptacle connectors?

A: Substitution eligibility is determined by matching the following parameters: connector type (receptacle), contact type (female socket), number of positions (5), mating pitch (0.079" / 2.00mm), mounting configuration (surface mount, right angle), termination method (solder), contact finish specification (gold plating), current rating (3.9A per contact), operating temperature range (-55°C to 125°C), insulation material (LCP), and compliance status (ROHS3, MSL 1).

Q: Does packaging affect substitution compatibility?

A: Both parts are supplied in tube packaging. Packaging format does not affect electrical or mechanical compatibility. Selection may be influenced by inventory quantity or procurement preferences.

Q: Are both parts suitable for board-to-board and cable applications?

A: Yes. Both the MMS-105-02-LM-SH and MMS-105-02-L-SH are specified for board-to-board or cable style applications with identical push-pull fastening and solder termination.

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. Both parts carry this rating, ensuring consistent handling and storage conditions.
