Amphenol ICC 55510-148 Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 55510-148 is a 48-position receptacle connector in the Minitek® 2.00mm series, designed for surface mount board-to-board applications. This connector features 0.079" (2.00mm) pitch, gold-plated mating contacts, and operates across -55°C to 125°C. The part is classified as obsolete, making equivalent substitutes necessary for new designs and ongoing production support. Active alternatives from both Amphenol ICC and Samtec Inc. provide direct functional replacement with enhanced compliance and availability.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters: connector type (receptacle), contact type (female socket), number of positions (48), mating pitch (0.079" / 2.00mm), number of rows (2), row spacing (0.079" / 2.00mm), mounting type (surface mount), termination method (solder), fastening type (push-pull), contact finish (gold), operating temperature range (-55°C ~ 125°C), insulation color (black), and insulation height (0.177" / 4.50mm).

All substitute parts listed meet these core electrical and mechanical parameters. Variations in contact finish thickness, insulation material composition, packaging format, and RoHS compliance status do not affect functional interchangeability for board-to-board mating applications. The Amphenol ICC 55510-148LF represents a direct variant with improved RoHS compliance. Samtec MMS series parts provide cross-manufacturer alternatives with equivalent performance characteristics and active product status.

Engineering Selection Recommendations

Amphenol ICC 55510-148LF is the primary direct replacement for the obsolete 55510-148. Both parts share identical mechanical and electrical specifications within the Minitek® 2.00mm series. The 55510-148LF carries active product status and RoHS compliance, addressing regulatory requirements for new designs while maintaining full functional compatibility.

Samtec MMS series alternatives (MMS-124-02-F-DV, MMS-124-02-L-DV variants) provide cross-manufacturer substitution with active product status and ROHS3 compliance. These parts maintain all critical mating parameters and operating characteristics. Samtec variants feature Liquid Crystal Polymer (LCP) insulation material instead of standard plastic, offering enhanced dimensional stability and thermal performance. Current rating specifications differ (Samtec rates 3.9A per contact versus Amphenol's 2A), providing additional margin for applications within the original 2A specification.

Packaging and feature variants within the Samtec MMS-124 family address specific manufacturing requirements: Tape & Reel (TR) packaging for automated assembly, board guide features for mechanical alignment, and pick-and-place compatibility for high-volume production. Selection among MMS variants depends on assembly process requirements rather than electrical performance.

MMS-124-02-L-DV-K-01 contains 47 loaded positions instead of 48, making it unsuitable for direct substitution in applications requiring all 48 positions.

Frequently Asked Questions (FAQ)

Q: Can I substitute the obsolete 55510-148 with the 55510-148LF?

A: Yes. Both parts are functionally identical Minitek® 2.00mm receptacles with 48 positions, 0.079" pitch, and identical electrical ratings. The 55510-148LF is the active production equivalent with RoHS compliance.

Q: Are Samtec MMS-124 series connectors compatible with Amphenol ICC Minitek® 2.00mm plugs?

A: Yes. All substitute parts maintain the 0.079" (2.00mm) mating pitch, 2-row configuration, and push-pull fastening system. Mating compatibility is preserved across manufacturers.

Q: What is the difference between MMS-124-02-F-DV and MMS-124-02-L-DV variants?

A: The "F" designation indicates a floating contact design, while "L" indicates a board guide feature for mechanical alignment. Both are electrically equivalent; selection depends on PCB layout requirements and assembly process needs.

Q: Why do Samtec parts specify 3.9A per contact while the original part is rated 2A?

A: Samtec's higher current rating reflects the performance capability of their connector design. Applications designed for 2A operation remain fully compatible and operate within safe margins.

Q: What does the "-TR" suffix indicate in part numbers like MMS-124-02-L-DV-A-K-TR?

A: The "-TR" suffix denotes Tape & Reel packaging format, suitable for automated pick-and-place assembly. Tube packaging variants (without -TR) are available for manual assembly or lower-volume applications.

Q: Is MMS-124-02-L-DV-K-01 a suitable replacement?

A: No. This variant contains only 47 loaded positions instead of 48, making it incompatible with applications requiring all 48 contact positions.

Q: What packaging options are available for these substitutes?

A: Amphenol ICC 55510-148LF is supplied in Tube packaging. Samtec MMS variants are available in Tube, Tape & Reel, or unspecified packaging depending on the specific part number suffix.
