CLT-112-02-L-D-P Equivalent & Substitute Parts

Part Overview

The CLT-112-02-L-D-P is a 24-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 equivalent parts may be required due to packaging availability, inventory constraints, or specific application requirements for enhanced contact durability or voltage rating specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the CLT-112-02-L-D-P is determined by strict alignment of the following core parameters:

• Connector Type: Receptacle
• Number of Positions: 24
• 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
• Insulation Material: Liquid Crystal Polymer (LCP)
• Operating Temperature Range: -55°C ~ 125°C
• Material Flammability Rating: UL94 V-0

The substitute part SMM-112-02-S-D meets all mandatory substitution criteria. Variations in contact finish thickness, insulation height, current rating, and voltage rating do not preclude substitution when these parameters are not critical to the application.

Parameter Comparison

Engineering Selection Recommendations

Both CLT-112-02-L-D-P and SMM-112-02-S-D are Active products with full RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Selection between these parts should be based on application-specific requirements:

The CLT-112-02-L-D-P provides higher current capacity at 4.1A per contact with phosphor bronze contact material and is supplied in tube packaging. The SMM-112-02-S-D (Tiger Eye™ SMM series) offers increased contact finish thickness (30.0µin versus 10.0µin), greater insulation height (0.140" versus 0.083"), beryllium copper contact material, and specified voltage rating of 350VAC, supplied in bulk packaging. Both connectors maintain identical operating temperature range (-55°C to 125°C) and UL94 V-0 flammability rating.

Frequently Asked Questions (FAQ)

Q: Can SMM-112-02-S-D directly replace CLT-112-02-L-D-P in existing designs?

A: Yes. Both connectors share identical mating pitch (0.079"), position count (24), row configuration (2 rows), mounting type (surface mount), termination method (solder), and fastening mechanism (push-pull). Mechanical and electrical compatibility is established through these core parameters.

Q: What is the significance of the different contact finish thicknesses?

A: The SMM-112-02-S-D features 30.0µin (0.76µm) gold plating compared to 10.0µin (0.25µm) on the CLT-112-02-L-D-P. Thicker plating provides enhanced durability and contact longevity in high-cycle mating applications. Selection depends on application cycle requirements.

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

A: The CLT-112-02-L-D-P is rated at 4.1A per contact while SMM-112-02-S-D is rated at 3.2A per contact. This difference reflects the distinct contact material compositions (phosphor bronze versus beryllium copper) and design characteristics. Applications requiring maximum current capacity should specify CLT-112-02-L-D-P.

Q: What packaging differences exist?

A: CLT-112-02-L-D-P is supplied in tube packaging, while SMM-112-02-S-D is supplied in bulk packaging. Packaging selection affects handling, storage, and pick-and-place automation compatibility. Verify packaging requirements for your manufacturing process.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both CLT-112-02-L-D-P and SMM-112-02-S-D are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic component manufacturing and distribution.
