Amphenol ICC 55508-024LF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 55508-024LF is a 24-position receptacle connector in the Minitek® 2.00mm series, designed for board-to-board surface mount applications. This connector features a 0.079" (2.00mm) pitch with dual-row configuration, gold-plated mating contacts, and push-pull fastening. The part is currently active in production with 672 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design flexibility permits component interchange based on equivalent electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts CLT-112-02-G-D and CLT-112-02-L-D (Samtec Inc.) are qualified as equivalent alternatives based on the following critical parameters:

Matching Parameters:

• Connector type: Receptacle with female socket contacts
• Position count: 24 positions in dual-row configuration
• Mating pitch: 0.079" (2.00mm) with identical row spacing
• Mounting: Surface mount with solder termination
• Fastening: Push-pull mechanism
• Contact material: Phosphor bronze with gold mating finish
• Operating temperature: -55°C ~ 125°C
• Flammability: UL94 V-0
• Moisture sensitivity: MSL 1 (Unlimited)
• Compliance: RoHS3 and REACH Unaffected

Differentiation: The primary distinction between substitute parts is the contact finish on the post: CLT-112-02-G-D features gold post finish, while CLT-112-02-L-D features tin post finish. Both substitutes provide higher current rating (4.1A per contact) compared to the main part (2A), and utilize Liquid Crystal Polymer (LCP) insulation material instead of standard plastic.

Parameter Comparison

Engineering Selection Recommendations

All three parts maintain active product status and meet equivalent compliance requirements. The 55508-024LF and both CLT-112 variants satisfy UL94 V-0 flammability standards, RoHS compliance, REACH unaffected status, and MSL 1 moisture sensitivity classification.

Selection between the main part and substitutes should be based on the following considerations:

55508-024LF (Amphenol ICC): Primary choice when Minitek® 2.00mm series specification is required. Suitable for applications with 2A current requirements and standard plastic insulation material.

CLT-112-02-G-D (Samtec): Alternative when higher current capacity (4.1A per contact) is beneficial and gold post finish is preferred for enhanced corrosion resistance. LCP insulation material provides improved thermal and chemical resistance compared to standard plastic.

CLT-112-02-L-D (Samtec): Alternative when higher current capacity (4.1A per contact) is required with tin post finish. LCP insulation material offers equivalent performance benefits as CLT-112-02-G-D.

All parts are suitable for general purpose, industrial, and medical applications within the specified operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Are CLT-112-02-G-D and CLT-112-02-L-D interchangeable with 55508-024LF?

A: Yes, both Samtec parts are mechanically and electrically compatible substitutes. They share identical mating pitch (0.079"), position count (24), row configuration (2 rows), mounting type (surface mount), and fastening mechanism (push-pull). All three parts are rated for -55°C to 125°C operation and meet UL94 V-0 flammability requirements.

Q: What is the difference between CLT-112-02-G-D and CLT-112-02-L-D?

A: The primary difference is the contact finish on the post: CLT-112-02-G-D features gold post finish, while CLT-112-02-L-D features tin post finish. Both parts provide identical mating contact finish (gold), current rating (4.1A per contact), and insulation material (LCP).

Q: Does the insulation height difference affect compatibility?

A: The 55508-024LF has an insulation height of 0.091" (2.30mm), while both CLT-112 variants measure 0.083" (2.10mm). This 0.008" (0.20mm) difference is within typical PCB design tolerances for board-to-board connectors and does not prevent mechanical or electrical compatibility.

Q: What is the advantage of the higher current rating in CLT-112 parts?

A: CLT-112-02-G-D and CLT-112-02-L-D are rated for 4.1A per contact compared to 2A for the 55508-024LF. This higher current capacity provides design margin for applications requiring increased power delivery without exceeding contact thermal limits.

Q: Are all three parts RoHS compliant?

A: Yes. The 55508-024LF is RoHS Compliant, while CLT-112-02-G-D and CLT-112-02-L-D are ROHS3 Compliant. Both compliance levels meet current RoHS requirements and are suitable for equivalent applications.

Q: What is the significance of LCP insulation material in the Samtec parts?

A: Liquid Crystal Polymer (LCP) insulation provides improved thermal stability, chemical resistance, and dimensional stability compared to standard plastic insulation. This material choice enhances connector performance in demanding industrial and medical environments.
