Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 55508-304LF is determined by strict alignment of the following critical parameters:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 4
• Pitch - Mating: 0.079" (2.00mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.079" (2.00mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Operating Temperature Range: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0

The Samtec Inc. CLT-102-02-G-D meets all critical substitution criteria. Both connectors share identical mechanical pitch, row configuration, mounting methodology, and temperature operating range. Both maintain UL94 V-0 flammability compliance and unlimited moisture sensitivity classification. The CLT-102-02-G-D provides equivalent board-to-board connectivity with push-pull fastening and solder termination.

Parameter Comparison

Engineering Selection Recommendations

Both the 55508-304LF and CLT-102-02-G-D are Active status products with full compliance certifications. The 55508-304LF carries RoHS Compliant status and REACH Affected designation. The CLT-102-02-G-D carries ROHS3 Compliant status and REACH Unaffected designation. Selection between these parts should be based on specific supply chain requirements, inventory availability, and regulatory compliance obligations for the end application. Both connectors satisfy identical mechanical and electrical interface requirements for board-to-board connectivity in the specified operating environment.

Frequently Asked Questions (FAQ)

Q: Can the CLT-102-02-G-D directly replace the 55508-304LF in existing designs?

A: Yes. Both connectors share identical pitch (0.079"), row configuration (2 rows), position count (4), mounting type (surface mount), and termination method (solder). The mechanical and electrical interfaces are equivalent.

Q: What are the differences in current rating between these connectors?

A: The 55508-304LF is rated at 2A total current. The CLT-102-02-G-D is rated at 4.1A per contact. The CLT-102-02-G-D provides higher current capacity per individual contact.

Q: Are there differences in contact finish specifications?

A: The 55508-304LF specifies 15.0µin (0.38µm) gold plating on mating contacts. The CLT-102-02-G-D specifies 10.0µin (0.25µm) gold plating on mating contacts. Both provide gold-plated mating surfaces suitable for the specified applications.

Q: What is the difference in insulation material?

A: The 55508-304LF uses plastic insulation material. The CLT-102-02-G-D uses Liquid Crystal Polymer (LCP) insulation material. Both materials maintain UL94 V-0 flammability compliance.

Q: Are both connectors suitable for medical applications?

A: The 55508-304LF explicitly lists medical applications in its specification. The CLT-102-02-G-D does not specify applications in the provided data. Application suitability should be confirmed against specific medical device requirements and regulatory standards.

Q: What is the packaging difference?

A: The 55508-304LF is supplied in Tube packaging. The CLT-102-02-G-D is supplied in Bulk packaging. Packaging selection may affect handling, storage, and procurement workflows.

Q: Do both connectors meet RoHS compliance requirements?

A: The 55508-304LF is RoHS Compliant. The CLT-102-02-G-D is ROHS3 Compliant. Both meet RoHS requirements; ROHS3 represents the current RoHS directive revision.
