Amphenol ICC 55508-036LF Equivalent & Substitute Parts

Part Overview

The Amphenol ICC 55508-036LF is a 36-position receptacle connector featuring 0.079" (2.00mm) pitch, surface mount termination, and gold-plated mating contacts. This connector is part of the Minitek® 2.00mm series and is currently active in production with 702 units in stock. The part is designed for board-to-board applications requiring push-pull fastening and operates across -55°C to 125°C temperature range.

Equivalent and substitute parts are identified when design requirements change, inventory constraints occur, or when alternative manufacturers offer compatible solutions meeting the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 55508-036LF are identified based on the following critical parameters that determine functional compatibility:

Primary Matching Criteria:

• Connector type: Receptacle
• Contact type: Female socket
• Number of positions: 36
• 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
• Contact finish - mating: Gold
• Operating temperature range: -55°C ~ 125°C
• Material flammability rating: UL94 V-0

The Samtec CLT series connectors (CLT-118-02-G-D and CLT-118-02-L-D) meet all primary matching criteria, establishing them as valid substitutes. Differences in contact finish thickness, insulation material, and current rating per contact do not prevent substitution when the application requirements fall within the specified parameters of both parts.

Parameter Comparison

Engineering Selection Recommendations

55508-036LF (Primary Part): This connector remains the recommended choice for new designs. It is currently active in production with adequate inventory (702 units in stock) and carries RoHS compliance certification. The part meets all standard industrial and medical application requirements within its specified electrical and thermal parameters.

CLT-118-02-L-D (Preferred Substitute): This Samtec connector is the primary substitute option. It maintains active product status, offers higher current capacity per contact (4.1A versus 2A), and carries ROHS3 compliance. The insulation material differs (LCP versus plastic), providing enhanced thermal and chemical resistance. Inventory availability is comparable (896 units in stock). The reduced insulation height (0.083" versus 0.091") must be evaluated for mechanical clearance in the target application.

CLT-118-02-G-D (Secondary Substitute): This variant is functionally equivalent to CLT-118-02-L-D but carries discontinued product status at DiGi Electronics. Selection of this part should be limited to applications where existing inventory or long-term supply agreements are established. The gold post finish differs from the tin finish of the primary substitute.

Frequently Asked Questions (FAQ)

Q: Can CLT-118-02-L-D directly replace 55508-036LF in existing designs?

A: Yes, provided that the reduced insulation height (0.083" versus 0.091") does not create mechanical interference with the PCB layout or adjacent components. All electrical and mating characteristics are compatible.

Q: What is the significance of the insulation material difference between the 55508-036LF (plastic) and CLT-118 series (LCP)?

A: Liquid Crystal Polymer (LCP) offers superior thermal stability, chemical resistance, and dimensional consistency compared to standard plastic. This difference does not prevent substitution but may improve performance in high-temperature or chemically aggressive environments.

Q: Does the higher current rating of the CLT series (4.1A per contact versus 2A) affect compatibility?

A: No. Higher current capacity indicates greater design margin and does not create compatibility issues. The substitute part can safely handle applications designed for the lower current rating of the original part.

Q: Why is CLT-118-02-G-D listed as discontinued?

A: Discontinuation status is specific to DiGi Electronics's inventory management and does not reflect the part's technical viability. Availability through alternative distributors or direct manufacturer channels may exist.

Q: Are there mechanical considerations when switching between these connectors?

A: The primary consideration is the 0.008" (0.20mm) reduction in insulation height for the CLT series. PCB layout, mating connector clearance, and component spacing must be evaluated to ensure no physical interference occurs.

Q: Do all three connectors meet the same compliance standards?

A: All three parts meet UL94 V-0 flammability requirements and MSL 1 moisture sensitivity levels. The 55508-036LF carries RoHS compliance, while both CLT variants carry ROHS3 compliance, representing equivalent regulatory status for RoHS requirements.
