CLT-118-02-L-D-P Equivalent & Substitute Parts

Part Overview

The CLT-118-02-L-D-P is a 36-position receptacle connector manufactured by Samtec Inc., designed for board-to-board applications with surface mount termination. This connector features a 0.079" (2.00mm) pitch, gold-plated mating contacts, and operates across -55°C to 125°C. The product maintains Active status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Alternative models are identified to support inventory flexibility, packaging preferences, and application-specific requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CLT-118-02-L-D-P is determined by strict alignment of the following parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Arrangement: 36 positions in 2-row configuration
• Pitch Specifications: 0.079" (2.00mm) mating pitch and row spacing
• Mounting & Termination: Surface mount with solder termination
• Fastening Mechanism: Push-pull fastening type
• Mating Contact Finish: Gold plating on mating surfaces
• Insulation Material: Liquid Crystal Polymer (LCP)
• Environmental Compliance: UL94 V-0 flammability rating, RoHS3 compliance, MSL 1 rating

The substitute part SMM-118-02-S-D meets all mandatory substitution criteria. Variations in contact finish thickness, insulation height, current rating, and voltage rating represent design differences within the same functional category and do not preclude substitution when these parameters are acceptable for the target application.

Parameter Comparison

Engineering Selection Recommendations

Both CLT-118-02-L-D-P and SMM-118-02-S-D maintain Active product status with identical environmental compliance certifications (UL94 V-0, RoHS3, MSL 1). Selection between these parts should be based on application-specific electrical requirements and packaging constraints.

The CLT-118-02-L-D-P provides higher current capacity (4.1A per contact) with phosphor bronze contacts and is supplied in tube packaging. The SMM-118-02-S-D offers increased contact finish thickness (30.0µin vs. 10.0µin), greater insulation height (0.140" vs. 0.083"), beryllium copper contacts, and a specified voltage rating of 350VAC, with bulk packaging availability.

Applications requiring maximum current density favor the CLT-118-02-L-D-P. Applications prioritizing enhanced contact durability, higher voltage specifications, or bulk procurement favor the SMM-118-02-S-D. Both parts satisfy identical mechanical mating requirements and thermal operating ranges.

Frequently Asked Questions (FAQ)

Q: Can SMM-118-02-S-D directly replace CLT-118-02-L-D-P in existing designs?

A: Yes, provided the application does not require the higher current rating of the CLT-118-02-L-D-P (4.1A vs. 3.2A per contact). The SMM-118-02-S-D meets all mechanical mating specifications, pitch requirements, and environmental compliance standards. Verify that the increased insulation height (0.140" vs. 0.083") does not create clearance conflicts in the PCB layout.

Q: What are the key differences between these two parts?

A: Primary differences include contact material (phosphor bronze vs. beryllium copper), current rating (4.1A vs. 3.2A), contact finish thickness (10.0µin vs. 30.0µin), insulation height (0.083" vs. 0.140"), voltage rating specification (not specified vs. 350VAC), and packaging format (tube vs. bulk).

Q: Are both parts RoHS3 compliant?

A: Yes, both CLT-118-02-L-D-P and SMM-118-02-S-D are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating.

Q: Which part should be selected for high-current applications?

A: The CLT-118-02-L-D-P is specified for 4.1A per contact, making it suitable for applications requiring maximum current capacity. The SMM-118-02-S-D is rated at 3.2A per contact.

Q: Does packaging format affect electrical performance?

A: No. Tube and bulk packaging formats do not affect electrical or mechanical performance. Selection should be based on procurement volume requirements and inventory management practices.

Q: Are the mating interfaces identical between these parts?

A: Yes. Both parts feature identical 0.079" (2.00mm) pitch, 2-row configuration, 36-position count, and push-pull fastening mechanism. Mating with complementary connector types is mechanically and electrically compatible.
