Engineering Selection Recommendations

Direct Amphenol ICC Replacement: The 55510-324LF is the primary substitute for the obsolete 55510-324. Both parts share identical electrical and mechanical specifications with 24 positions, 2.00mm pitch, and -55°C to 125°C operating range. The 55510-324LF is active in production and RoHS compliant, making it the preferred choice for direct substitution in new designs and production restarts.

Cross-Manufacturer Alternatives: When Amphenol ICC parts are unavailable, the following active alternatives maintain core compatibility:

Molex 0791091211: Maintains 24-position, 2.00mm pitch configuration with push-pull fastening. Operates -55°C to 125°C. Current rating is 1A per contact (lower than original 2A specification). Voltage rating is 125V (lower than original 200V specification). Suitable for applications within these reduced electrical parameters.
Hirose A3-24DA-2SV(71) and A3A-24DA-2SV(71): Both maintain 24-position, 2.00mm pitch with push-pull fastening. Operating temperature limited to -55°C to 85°C (narrower than original). Current rating 1A per contact. Voltage rating 200VAC. The A3A variant includes board guide feature. Suitable for general purpose and telecommunications applications within specified temperature range.
Samtec MMS Series (MMS-112-02-F-DV-A-K-TR, MMS-112-02-F-DV-A-M-TR, MMS-112-02-F-DV-A-P-TR, MMS-112-02-S-DV-K-TR): All maintain 24-position, 2.00mm pitch with -55°C to 125°C operating range. Current rating 3.9A per contact (exceeds original specification). Liquid Crystal Polymer insulation. Variants include board guide and pick-and-place features. RoHS3 compliant.
Samtec TLE Series (TLE-112-01-G-DV, TLE-112-01-G-DV-A-K): Pass-through receptacle design with 24 positions, 2.00mm pitch, -55°C to 125°C operating range. Current rating 3.2A per contact. Liquid Crystal Polymer insulation. TLE-112-01-G-DV-A-K includes board guide. RoHS3 compliant.

Selection should prioritize active production status and RoHS compliance for new designs. For legacy system maintenance, the 55510-324LF provides direct compatibility. Cross-manufacturer alternatives require verification of electrical parameter adequacy for specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the 55510-324LF directly replace the obsolete 55510-324?

A: Yes. The 55510-324LF is the active production equivalent with identical electrical and mechanical specifications: 24 positions, 0.079" (2.00mm) pitch, surface mount, gold-plated contacts, -55°C to 125°C operating range, 2A current rating, and 200V voltage rating. The primary difference is RoHS compliance status.

Q: What are the key differences between Amphenol ICC and cross-manufacturer substitutes?

A: Amphenol ICC 55510-324LF maintains exact electrical specifications (2A, 200V). Molex 0791091211 reduces current to 1A and voltage to 125V. Hirose A3 series limits operating temperature to -55°C to 85°C and reduces current to 1A. Samtec MMS and TLE series increase current capacity (3.2A to 3.9A per contact) and maintain full temperature range. All maintain 24-position, 2.00mm pitch configuration.

Q: Are there packaging differences between substitute parts?

A: Yes. The 55510-324 was supplied in standard packaging (status obsolete). The 55510-324LF is supplied in tubes. Samtec MMS-112-02-F-DV-A-K-TR and MMS-112-02-F-DV-A-P-TR are supplied in tape and reel. Samtec TLE series are supplied in tubes. Molex and Hirose alternatives are supplied in tubes. Packaging selection depends on assembly process requirements.

Q: Which substitute is best for new product designs?

A: The 55510-324LF is recommended for new designs requiring direct compatibility with the original specification. For designs that can accommodate higher current capacity, Samtec MMS or TLE series offer enhanced performance with RoHS3 compliance and active production status.

Q: Do all substitutes maintain the same operating temperature range?

A: No. The 55510-324, 55510-324LF, Molex 0791091211, and Samtec MMS and TLE series all operate -55°C to 125°C. Hirose A3-24DA-2SV(71) and A3A-24DA-2SV(71) are limited to -55°C to 85°C. Verify application temperature requirements before selection.

Q: What is the difference between TLE-112-01-G-DV and TLE-112-01-G-DV-A-K?

A: Both are 24-position, 2.00mm pitch pass-through receptacles with identical electrical specifications. The TLE-112-01-G-DV-A-K includes a board guide feature for improved alignment during mating. Selection depends on mechanical assembly requirements.

Q: Are all listed substitutes RoHS compliant?

A: The original 55510-324 is RoHS non-compliant. All active substitutes listed are RoHS compliant or ROHS3 compliant, making them suitable for applications requiring environmental compliance.
