Substitute Part Grouping Explanation
Substitution eligibility is determined by strict alignment with the following core parameters: 48-position count, 0.079" (2.00mm) mating pitch, 2-row configuration with 0.079" row spacing, surface mount termination, push-pull fastening, gold mating contact finish, black insulation, 0.177" (4.50mm) insulation height, -55°C to 125°C operating temperature range, phosphor bronze contact material, and square contact geometry.
The Amphenol ICC 55510-348LF variant maintains identical electrical and mechanical specifications while upgrading to RoHS Compliant status and tin-lead post finish. Samtec MMS series substitutes (MMS-124-02-F-DV, MMS-124-02-F-DV-A, MMS-124-02-F-DV-K-TR, MMS-124-02-L-DV-A, MMS-124-02-L-DV-A-K, MMS-124-02-L-DV-A-K-TR, MMS-124-02-L-DV-A-TR, MMS-124-02-L-DV-K, MMS-124-02-L-DV-K-01) meet all core mechanical and electrical requirements. Differences in contact finish thickness, insulation material (LCP vs. plastic), current rating per contact (3.9A vs. 2A), and packaging format do not affect functional interchangeability for board-to-board 48-position 2.00mm pitch applications.

Engineering Selection Recommendations
The 55510-348 is obsolete and should be replaced in new designs. The 55510-348LF provides the most direct upgrade path, maintaining Amphenol ICC manufacturing while achieving RoHS Compliance and active product status. This variant is suitable for applications requiring continuity with existing Amphenol ICC supply chains.
For new designs and long-term availability, Samtec MMS-124 series substitutes are recommended. All MMS variants meet core mechanical and electrical requirements. Selection among MMS options depends on packaging and feature requirements:
MMS-124-02-F-DV and MMS-124-02-F-DV-A are base configurations without board guide features. MMS-124-02-F-DV-K-TR includes pick-and-place capability in tape-and-reel packaging.
MMS-124-02-L-DV-A, MMS-124-02-L-DV-A-K, and MMS-124-02-L-DV-A-TR include board guide features. MMS-124-02-L-DV-A-K-TR combines board guide with pick-and-place in tape-and-reel format. MMS-124-02-L-DV-K and MMS-124-02-L-DV-K-01 provide pick-and-place capability with board guide in tube packaging.
MMS-124-02-L-DV-K-01 is loaded with 47 positions instead of 48, making it unsuitable for applications requiring all 48 positions.
All Samtec MMS variants achieve ROHS3 Compliance where specified, supporting modern regulatory requirements. Current rating per contact (3.9A) exceeds the original 2A specification, providing enhanced electrical capacity.
Frequently Asked Questions (FAQ)
Q: Can MMS-124 series connectors directly replace 55510-348 in existing designs?
A: Yes. All MMS-124 variants maintain identical mating pitch (0.079" / 2.00mm), position count (48), row configuration (2 rows with 0.079" spacing), mounting type (surface mount), termination (solder), fastening (push-pull), contact finish (gold), insulation geometry (0.177" height, black), operating temperature range (-55°C to 125°C), and contact material (phosphor bronze, square geometry). Mechanical and electrical interchangeability is confirmed.
Q: What is the difference between MMS-124-02-F-DV and MMS-124-02-L-DV-A?
A: The primary difference is the board guide feature. MMS-124-02-L-DV-A includes a board guide, while MMS-124-02-F-DV does not. Board guide variants provide additional mechanical alignment during assembly. Both maintain identical electrical and core mechanical specifications.
Q: Why do some MMS variants have higher current ratings (3.9A per contact) than the original 55510-348 (2A)?
A: The MMS series is engineered with enhanced contact geometry and materials that support higher current capacity. The higher rating does not affect compatibility; applications designed for 2A operation remain fully supported.
Q: What packaging options are available for MMS-124 substitutes?
A: Tube packaging is standard for most variants. Tape-and-reel (TR) packaging is available for MMS-124-02-F-DV-K-TR, MMS-124-02-L-DV-A-K-TR, and MMS-124-02-L-DV-A-TR, supporting automated pick-and-place assembly. Packaging selection does not affect electrical or mechanical performance.
Q: Is MMS-124-02-L-DV-K-01 suitable as a substitute?
A: No. MMS-124-02-L-DV-K-01 is loaded with 47 positions instead of 48. It is not compatible with applications requiring all 48 positions.
Q: What is the compliance difference between 55510-348 and 55510-348LF?
A: The 55510-348LF achieves RoHS Compliance and active product status, while the original 55510-348 is RoHS non-compliant and obsolete. The 55510-348LF is the recommended Amphenol ICC variant for new designs.
Q: Are all MMS-124 variants ROHS3 compliant?
A: ROHS3 Compliance is specified for MMS-124-02-F-DV, MMS-124-02-F-DV-K-TR, MMS-124-02-L-DV-A, MMS-124-02-L-DV-A-K, MMS-124-02-L-DV-A-K-TR, and MMS-124-02-L-DV-K. Compliance status is not specified for MMS-124-02-F-DV-A, MMS-124-02-L-DV-A-TR, and MMS-124-02-L-DV-K-01.
