Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the CLT-103-02-L-D is determined by the following critical parameters:

• Connector type (Receptacle)
• Number of positions (6)
• Pitch spacing (0.079" / 2.00mm)
• Number of rows (2)
• Row spacing (0.079" / 2.00mm)
• Mounting type (Surface Mount)
• Fastening type (Push-Pull)
• Contact finish (Gold)
• Operating temperature range (-55°C ~ 125°C)
• Insulation material (LCP)

The SMM-103-02-S-D meets all these core substitution criteria. Both connectors share identical mechanical and electrical interface specifications, enabling direct functional replacement in board-to-board applications.

Parameter Comparison

Engineering Selection Recommendations

The SMM-103-02-S-D is the qualified substitute for the discontinued CLT-103-02-L-D. Both connectors maintain identical mechanical interfaces and core electrical specifications required for board-to-board connectivity.

Design considerations for substitution:

The SMM-103-02-S-D features increased insulation height (0.140" vs 0.083") and thicker gold plating on mating contacts (30.0µin vs 10.0µin), providing enhanced durability and contact reliability. The contact material differs (Beryllium Copper vs Phosphor Bronze), with the substitute rated at 3.2A per contact compared to 4.1A for the original part. The SMM-103-02-S-D includes a specified voltage rating of 350VAC.

Both parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and identical operating temperature ranges. The SMM-103-02-S-D is actively manufactured and available in higher inventory quantities, supporting long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the SMM-103-02-S-D directly replace the CLT-103-02-L-D in existing designs?

A: Yes. Both connectors share identical pitch spacing (0.079"), position count (6), row configuration (2 rows), and mounting type (surface mount). The mechanical interface and electrical contact arrangement are compatible for board-to-board applications.

Q: What are the differences in contact current ratings?

A: The CLT-103-02-L-D is rated at 4.1A per contact, while the SMM-103-02-S-D is rated at 3.2A per contact. Applications requiring the full 4.1A rating per contact should be evaluated against the substitute's 3.2A specification.

Q: Why is the insulation height different between the two parts?

A: The SMM-103-02-S-D features increased insulation height (0.140" vs 0.083"), which may affect PCB layout and mating connector clearance. Verify that the increased height does not conflict with existing mechanical constraints or mating connector specifications.

Q: Are both parts RoHS compliant?

A: Yes. Both the CLT-103-02-L-D and SMM-103-02-S-D are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the difference in gold plating thickness?

A: The CLT-103-02-L-D has 10.0µin (0.25µm) gold plating on mating contacts, while the SMM-103-02-S-D has 30.0µin (0.76µm). The thicker plating on the substitute provides enhanced contact durability and wear resistance.

Q: Is the SMM-103-02-S-D actively manufactured?

A: Yes. The SMM-103-02-S-D is active and available in higher inventory quantities (1522 pcs), compared to the discontinued CLT-103-02-L-D, ensuring reliable long-term supply availability.
