Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 55508-314LF is determined by strict alignment of the following critical parameters:

• Connector type (Receptacle)
• Number of positions (14)
• Pitch and row spacing (0.079" / 2.00mm)
• Number of rows (2)
• Mounting type (Surface Mount)
• Fastening type (Push-Pull)
• Contact finish material (Gold)
• Operating temperature range (-55°C ~ 125°C)
• Material flammability rating (UL94 V-0)
• Regulatory compliance (RoHS)

The Samtec Inc. CLT-107-02-G-D meets all these criteria, establishing it as a qualified equivalent substitute. Both parts share identical mechanical interfaces, electrical operating ranges, and regulatory certifications, enabling direct substitution in applications requiring 14-position, 2.00mm pitch board-to-board receptacle connectors.

Parameter Comparison

Engineering Selection Recommendations

Both the Amphenol ICC 55508-314LF and Samtec Inc. CLT-107-02-G-D are active production parts with equivalent mechanical and electrical specifications. The Amphenol part carries standard RoHS compliance, while the Samtec substitute carries ROHS3 compliance, indicating enhanced regulatory alignment. Both parts meet UL94 V-0 flammability requirements and operate across identical temperature ranges. Current rating differs between the parts (2A for Amphenol versus 4.1A per contact for Samtec), with the Samtec part offering higher current capacity. Selection between these parts should be based on inventory availability, lead time requirements, and application-specific current demands. The Samtec CLT-107-02-G-D is suitable for applications requiring higher current handling capability while maintaining full mechanical and thermal compatibility.

Frequently Asked Questions (FAQ)

Q: Can the Samtec CLT-107-02-G-D directly replace the Amphenol ICC 55508-314LF?

A: Yes. Both parts share identical connector type, position count, pitch, row configuration, mounting type, and fastening mechanism. Mechanical and electrical interfaces are equivalent, enabling direct substitution in board-to-board applications.

Q: What are the key differences between these parts?

A: The primary differences are current rating (Amphenol 2A versus Samtec 4.1A per contact), insulation material (Amphenol plastic versus Samtec liquid crystal polymer), and contact finish thickness on the post (Samtec specifies 3.00µin gold plating). Both parts maintain identical operating temperature ranges and flammability ratings.

Q: Are there any compliance or certification differences?

A: Both parts are RoHS compliant and carry EAR99 ECCN classification. The Samtec part carries ROHS3 compliance, representing a more recent regulatory standard. Both meet UL94 V-0 flammability requirements and share identical HTSUS classification.

Q: What is the impact of different insulation materials?

A: The Amphenol part uses plastic insulation while the Samtec part uses liquid crystal polymer (LCP). Both materials meet the specified UL94 V-0 flammability rating and operate across the same temperature range. Material selection does not affect mechanical compatibility or electrical performance in this application.

Q: Should I consider the higher current rating of the Samtec part?

A: The Samtec CLT-107-02-G-D provides 4.1A per contact capacity compared to the Amphenol 2A rating. If your application requires current levels between 2A and 4.1A per contact, the Samtec part offers additional margin. For applications operating at or below 2A, both parts are functionally equivalent.
