Amphenol ICC 55508-326LF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 55508-326LF is a 26-position receptacle connector with 0.079" (2.00mm) pitch, designed for board-to-board surface mount applications. This connector features gold-plated mating contacts, push-pull fastening, and operates across -55°C to 125°C. The part is currently active in production with 1033 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, inventory constraints occur, or design flexibility is required across compatible connector families. The Samtec CLT series connectors provide functional equivalence while maintaining electrical and mechanical compatibility with the 55508-326LF.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 55508-326LF is determined by strict alignment with the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Arrangement: 26 positions in 2-row configuration
• Pitch Specifications: 0.079" (2.00mm) mating pitch and row spacing
• Mounting & Termination: Surface mount with solder termination
• Fastening Mechanism: Push-pull fastening system
• Environmental Rating: Operating temperature -55°C to 125°C minimum
• Flammability Compliance: UL94 V-0 material rating
• Contact Material: Phosphor bronze construction

The Samtec CLT-113-02-G-D and CLT-113-02-L-D connectors satisfy all substitution criteria. Both maintain identical mechanical footprint, electrical interface, and environmental specifications. Differences in contact finish thickness and insulation material do not affect functional compatibility in board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Part - Amphenol ICC 55508-326LF: Active product status with 1033 units in stock. RoHS Compliant certification. Recommended for new designs and ongoing production where supply is not constrained.

Substitute Option 1 - Samtec CLT-113-02-G-D: Discontinued at DiGi Electronics with 856 units available. ROHS3 Compliant. Gold post finish provides enhanced contact durability. Suitable for applications requiring extended contact life or where gold plating specifications are critical.

Substitute Option 2 - Samtec CLT-113-02-L-D: Discontinued at DiGi Electronics with 701 units available. ROHS3 Compliant. Tin post finish. Functionally equivalent for standard board-to-board interconnect applications. Lower cost alternative when contact finish specifications permit.

Both Samtec alternatives maintain full mechanical and electrical compatibility. Selection between CLT-113-02-G-D and CLT-113-02-L-D depends on post-contact finish requirements and cost considerations, not functional performance.

Frequently Asked Questions (FAQ)

Q: Are the Samtec CLT-113 connectors mechanically compatible with the Amphenol ICC 55508-326LF?

A: Yes. Both connectors share identical mating pitch (0.079"), row spacing (0.079"), position count (26), and row configuration (2 rows). Surface mount footprints are compatible for board-to-board applications.

Q: What is the difference between CLT-113-02-G-D and CLT-113-02-L-D?

A: The primary difference is post-contact finish. CLT-113-02-G-D features gold plating on the post contacts, while CLT-113-02-L-D uses tin plating. Both maintain identical mating contact gold plating and electrical performance. Selection depends on post-contact durability requirements and application specifications.

Q: Can I use these connectors interchangeably in existing designs?

A: Yes, for board-to-board applications. All three connectors (55508-326LF, CLT-113-02-G-D, CLT-113-02-L-D) maintain identical electrical ratings, operating temperature range, and mechanical interface specifications. No design modifications are required.

Q: What is the current rating difference between the main part and substitutes?

A: The 55508-326LF specifies 2A current rating. The Samtec CLT-113 series specifies 4.1A per contact. This higher rating in the substitute parts does not affect compatibility and provides additional design margin for current-carrying applications.

Q: Are there compliance differences between these connectors?

A: The 55508-326LF is RoHS Compliant. Both Samtec alternatives are ROHS3 Compliant, representing a more recent compliance standard. All three connectors meet UL94 V-0 flammability requirements and maintain MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What should I consider when selecting between these three options?

A: For active production, the 55508-326LF is preferred due to active status and higher inventory. For substitute applications, choose CLT-113-02-G-D if enhanced post-contact durability is required, or CLT-113-02-L-D for standard applications where tin plating is acceptable. All three are electrically and mechanically interchangeable.
