CLT-107-02-L-D-P Equivalent & Substitute Parts

Part Overview

The CLT-107-02-L-D-P is a 14-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 the industrial temperature range of -55°C to 125°C. The part maintains Active product status and is fully RoHS3 compliant with MSL 1 rating, indicating no moisture sensitivity limitations.

Substitute parts become necessary when inventory constraints occur, when alternative packaging formats are required for manufacturing processes, or when design flexibility permits selection from equivalent connector families that maintain electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CLT-107-02-L-D-P is determined by strict alignment of the following critical parameters:

• Connector Type & Position Count: Must be receptacle configuration with exactly 14 positions
• Pitch & Row Configuration: Mating pitch of 0.079" (2.00mm) with 2-row layout and 0.079" row spacing
• Mounting & Termination: Surface mount with solder termination
• Fastening Mechanism: Push-pull fastening type
• Contact System: Female socket contacts with gold mating finish
• Environmental Compliance: UL94 V-0 flammability rating, RoHS3 compliance, and MSL 1 rating
• Operating Range: -55°C to 125°C temperature specification

The substitute part SMM-107-02-S-D meets all these critical parameters while differing in packaging format (Bulk vs. Tube), connector series designation (Tiger Eye™ SMM vs. CLT), and secondary specifications including contact material composition and current rating.

Parameter Comparison

Engineering Selection Recommendations

Both CLT-107-02-L-D-P and SMM-107-02-S-D maintain Active product status with identical RoHS3 compliance and MSL 1 ratings, confirming long-term availability and regulatory alignment for both options.

Selection between these parts should be based on:

CLT-107-02-L-D-P is appropriate when tube packaging is required for automated pick-and-place assembly processes or when the higher current rating of 4.1A per contact is a design requirement.

SMM-107-02-S-D is appropriate when bulk packaging aligns with manufacturing logistics, when the 350VAC voltage rating specification is required, or when the thicker gold plating (30.0µin vs. 10.0µin) provides additional contact durability for high-cycle mating applications. The Tiger Eye™ SMM series also supports both board-to-board and cable configurations, offering greater application flexibility.

Both connectors operate identically across the -55°C to 125°C temperature range and maintain equivalent mechanical compatibility through identical pitch, row spacing, and push-pull fastening specifications.

Frequently Asked Questions (FAQ)

Q: Can SMM-107-02-S-D directly replace CLT-107-02-L-D-P in existing designs?

A: Yes, from an electrical and mechanical standpoint. Both connectors share identical mating pitch (0.079"), row configuration (2 rows with 0.079" spacing), position count (14), and push-pull fastening. PCB footprints are compatible. However, the SMM-107-02-S-D has a taller insulation height (0.140" vs. 0.083"), which may affect board-level clearance in space-constrained layouts.

Q: What is the significance of the contact finish thickness difference?

A: The SMM-107-02-S-D features 30.0µin (0.76µm) gold plating compared to 10.0µin (0.25µm) on the CLT-107-02-L-D-P. Thicker plating extends contact life in high-cycle mating scenarios and provides enhanced corrosion resistance. For standard applications with moderate mating cycles, both thicknesses meet performance requirements.

Q: Why does the current rating differ between these parts?

A: The CLT-107-02-L-D-P is rated at 4.1A per contact while the SMM-107-02-S-D is rated at 3.2A per contact. This difference reflects the distinct contact material compositions (Phosphor Bronze vs. Beryllium Copper) and internal design parameters. Applications requiring the full 4.1A rating must use the CLT-107-02-L-D-P.

Q: What packaging differences exist, and how do they affect procurement?

A: CLT-107-02-L-D-P ships in Tube packaging (1125 pcs available), optimized for automated assembly. SMM-107-02-S-D ships in Bulk packaging (2298 pcs available), suitable for manual assembly or high-volume reel-based processes. Packaging selection depends on manufacturing workflow and inventory management requirements.

Q: Are both parts suitable for the same operating temperature range?

A: Yes. Both connectors operate across -55°C to 125°C and maintain UL94 V-0 flammability compliance across this entire range.

Q: Does the SMM-107-02-S-D's cable configuration capability affect board-to-board compatibility?

A: No. The SMM-107-02-S-D supports both board-to-board and cable configurations, but when used in board-to-board mode, it functions identically to the CLT-107-02-L-D-P. The expanded application flexibility does not compromise board-to-board performance.
