Substitute Part Grouping Explanation

Substitution eligibility for the MMS-110-02-L-DV-M is determined by strict equivalence across the following critical parameters:

  • Connector Type & Contact Configuration: Receptacle with female socket contacts
  • Position Count & Arrangement: 20 positions in 2-row configuration
  • Pitch Specifications: 0.079" (2.00mm) mating pitch and row spacing
  • Mounting Technology: Surface mount termination with solder connection
  • Electrical Performance: 3.9A per contact current rating
  • Environmental Compliance: Operating temperature range -55°C ~ 125°C and ROHS3 compliance
  • Contact Material & Finish: Gold-plated mating contacts with phosphor bronze base material

The substitute part MMS-110-02-LM-DV-K maintains full equivalence across all critical parameters, differing only in internal design designation (LM vs. L variant code) while preserving all functional and mechanical specifications.

Engineering Selection Recommendations

Both the MMS-110-02-L-DV-M and MMS-110-02-LM-DV-K are active production parts manufactured by Samtec Inc. with full ROHS3 compliance and MSL Level 1 rating. Selection between these parts should be based on:

  • Availability: MMS-110-02-LM-DV-K currently maintains 1145 units in stock versus 1093 units for MMS-110-02-L-DV-M
  • Supply Chain Requirements: Either part satisfies identical electrical, mechanical, and environmental specifications
  • Design Documentation: Verify that PCB layout and assembly documentation reference the selected part number to ensure proper component placement and soldering procedures

No performance degradation or functional compromise occurs when substituting between these parts, as all critical parameters remain equivalent.

Frequently Asked Questions (FAQ)

Q: Are MMS-110-02-L-DV-M and MMS-110-02-LM-DV-K mechanically interchangeable?

A: Yes. Both parts share identical mechanical dimensions, pitch specifications (0.079" / 2.00mm), mounting footprint, and surface mount termination requirements. PCB layouts designed for one part accommodate the other without modification.

Q: Do these connectors have identical electrical performance?

A: Yes. Both parts deliver 3.9A per contact current rating, operate across -55°C to 125°C, and feature gold-plated mating contacts with identical finish thickness (10.0µin / 0.25µm).

Q: What is the difference between the L and LM variant designations?

A: The variant codes (L vs. LM) represent internal design iterations within Samtec's MMS-110 product line. All specified electrical, mechanical, and environmental parameters remain identical between variants.

Q: Are both parts suitable for high-reliability applications?

A: Both parts meet ROHS3 compliance and carry MSL Level 1 rating, indicating unlimited shelf life under controlled storage. Compliance certifications are identical across both part numbers.

Q: Can I use either part for new PCB designs?

A: Yes. Either part number is acceptable for new designs. Confirm part availability with your supplier and document the selected part number in design specifications and assembly documentation.

Q: What is the pitch specification, and why is it critical for substitution?

A: Both parts feature 0.079" (2.00mm) mating pitch with identical row spacing. This pitch specification is fundamental to connector compatibility and must match exactly for proper mating with complementary connector halves.
