CLT-125-02-F-D Equivalent & Substitute Parts

Part Overview

The CLT-125-02-F-D is a 50-position receptacle connector manufactured by Samtec Inc., designed for board-to-board surface mount applications with 0.079" (2.00mm) pitch spacing. This connector features gold-plated mating contacts, push-pull fastening, and operates across the industrial temperature range of -55°C to 125°C. The part is currently active in production with 745 units in stock. Identifying equivalent and substitute parts is necessary when the primary part becomes unavailable, when alternative contact finishes are required for specific applications, or when inventory constraints necessitate sourcing from alternative stock positions.

Substitute Part Grouping Explanation

Substitution eligibility for the CLT-125-02-F-D is determined by strict equivalence across the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (50), mating pitch (0.079"/2.00mm), number of rows (2), row spacing (0.079"/2.00mm), mounting type (surface mount), fastening type (push-pull), operating temperature range (-55°C to 125°C), insulation material (LCP), contact material (phosphor bronze), and compliance certifications (UL94 V-0, ROHS3, REACH Unaffected).

The CLT-125-02-G-D qualifies as a manufacturer-recommended substitute because it maintains equivalence across all critical mechanical and electrical parameters. The primary distinction between these parts lies in contact finish specifications: the main part features tin post finish with 3.00µin gold mating finish, while the substitute features gold post finish with 10.0µin gold mating finish. Both parts share identical connector architecture, position count, pitch spacing, mounting methodology, and environmental ratings.

Parameter Comparison

Engineering Selection Recommendations

The CLT-125-02-G-D is designated as the manufacturer-recommended substitute for the CLT-125-02-F-D. Both parts maintain full mechanical and electrical compatibility within the CLT series architecture. The CLT-125-02-F-D remains the preferred selection for new designs due to its active production status and current availability. The CLT-125-02-G-D is suitable for applications where the part is already in use or where the enhanced mating contact finish thickness (10.0µin versus 3.00µin) provides additional durability benefits. Both parts satisfy identical compliance requirements: ROHS3 compliance, UL94 V-0 flammability rating, REACH unaffected status, and EAR99 export classification. The contact finish difference (tin post on main part versus gold post on substitute) does not affect electrical performance or environmental ratings but may influence long-term corrosion resistance in specific application environments.

Frequently Asked Questions (FAQ)

Q: Are CLT-125-02-F-D and CLT-125-02-G-D mechanically interchangeable?

A: Yes. Both parts share identical connector architecture, position count, pitch spacing (0.079"/2.00mm), row configuration, mounting type (surface mount), and fastening mechanism (push-pull). They are direct mechanical substitutes.

Q: What is the difference between these two parts?

A: The primary differences are contact finish specifications. The CLT-125-02-F-D features a tin post finish with 3.00µin gold mating finish. The CLT-125-02-G-D features a gold post finish with 10.0µin gold mating finish. Both maintain identical electrical performance and environmental ratings.

Q: Can I use CLT-125-02-G-D in place of CLT-125-02-F-D in existing designs?

A: Yes. The parts are electrically and mechanically equivalent. The enhanced mating contact finish thickness on the substitute part (10.0µin versus 3.00µin) provides equivalent or superior performance characteristics.

Q: What is the current availability status of each part?

A: The CLT-125-02-F-D is active in production with 745 units in stock. The CLT-125-02-G-D is discontinued at DiGi Electronics but has 869 units available from current inventory.

Q: Do both parts meet the same compliance standards?

A: Yes. Both parts are ROHS3 compliant, UL94 V-0 rated, REACH unaffected, and classified as EAR99 for export purposes. They share identical HTSUS classification (8536.69.4040).

Q: What is the operating temperature range for these connectors?

A: Both parts operate across -55°C to 125°C, suitable for industrial and extended temperature applications.

Q: What is the current rating per contact?

A: Both parts are rated for 4.1A per contact, with identical contact material (phosphor bronze) and insulation material (liquid crystal polymer).
