Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 55508-334LF are qualified based on the following critical parameters that define functional equivalence:

• 34-position configuration with 2-row layout
• 0.079" (2.00mm) mating pitch and row spacing
• Receptacle connector type with female socket contacts
• Surface mount solder termination
• Push-pull fastening mechanism
• Gold-plated mating contacts
• Operating temperature range of -55°C to 125°C
• UL94 V-0 flammability rating
• Square contact geometry with phosphor bronze material

The identified substitutes maintain these core parameters while allowing variations in insulation material, contact finish thickness, and current rating specifications that do not affect mechanical or electrical compatibility in standard board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

CLT-117-02-G-D is the primary substitute for 55508-334LF. Both parts maintain identical mating pitch, row configuration, and operating temperature specifications. The CLT-117-02-G-D features higher current rating (4.1A per contact versus 2A) and uses liquid crystal polymer insulation material, which provides enhanced thermal and mechanical properties. Both parts carry UL94 V-0 flammability certification and MSL 1 moisture sensitivity rating. The CLT-117-02-G-D is actively manufactured and maintains full RoHS3 compliance.

CLT-117-02-L-D is a secondary substitute option. This part is functionally equivalent to 55508-334LF in all critical mating and mechanical parameters. However, CLT-117-02-L-D is discontinued at DiGi Electronics and should be considered only when CLT-117-02-G-D is unavailable. The part retains the same current rating (4.1A per contact) and operating temperature range as CLT-117-02-G-D.

Frequently Asked Questions (FAQ)

Q: What determines if a connector can substitute for the 55508-334LF?

A: Substitutes must match the 34-position, 2-row configuration with 0.079" (2.00mm) mating pitch and row spacing. The connector must be a receptacle type with female socket contacts, surface mount solder termination, push-pull fastening, and gold-plated mating contacts. Operating temperature range must be -55°C to 125°C with UL94 V-0 flammability rating.

Q: Are the Samtec CLT-117 series connectors mechanically compatible with the 55508-334LF?

A: Yes. Both CLT-117-02-G-D and CLT-117-02-L-D maintain identical mating pitch, row spacing, and push-pull fastening geometry. The connectors are designed for board-to-board mating with compatible plug connectors.

Q: What is the difference between CLT-117-02-G-D and CLT-117-02-L-D?

A: Both parts are electrically and mechanically equivalent. The primary difference is the contact finish on the post: CLT-117-02-G-D uses gold finish while CLT-117-02-L-D uses tin finish. CLT-117-02-G-D is actively manufactured; CLT-117-02-L-D is discontinued at DiGi Electronics.

Q: Does the higher current rating of the Samtec substitutes affect compatibility?

A: No. The higher current rating (4.1A per contact) of CLT-117-02-G-D and CLT-117-02-L-D compared to the 55508-334LF (2A) represents enhanced capability and does not affect mechanical or electrical compatibility. Applications designed for 2A operation will function correctly with these substitutes.

Q: What is the significance of the insulation material difference?

A: The 55508-334LF uses plastic insulation while the Samtec substitutes use liquid crystal polymer (LCP). LCP provides superior thermal stability and mechanical properties. This material difference does not affect connector compatibility but may provide performance benefits in demanding thermal environments.

Q: Are all three connectors RoHS compliant?

A: Yes. The 55508-334LF is RoHS Compliant. Both CLT-117-02-G-D and CLT-117-02-L-D are ROHS3 Compliant. All three parts meet current RoHS requirements.
