Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFMC-111-L2-L-D-K is determined by strict alignment of the following critical parameters:

• Connector Type: Receptacle
• Number of Positions: 22
• Pitch - Mating: 0.050" (1.27mm)
• Number of Rows: 2
• Row Spacing - Mating: 0.050" (1.27mm)
• Mounting Type: Surface Mount
• Termination: Solder
• Fastening Type: Push-Pull
• Contact Finish - Mating: Gold
• Operating Temperature Range: -55°C ~ 125°C
• Insulation Material: Liquid Crystal Polymer (LCP)
• Material Flammability Rating: UL94 V-0
• Current Rating: 2.9A per Contact
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The SFMC-111-T2-L-D-P qualifies as a direct substitute based on matching all critical mechanical, electrical, and environmental parameters. The primary difference lies in the contact material composition: the main part uses Beryllium Copper while the substitute uses Phosphor Bronze. Both materials maintain equivalent electrical performance, current rating, and reliability within the specified operating conditions.

Parameter Comparison

Engineering Selection Recommendations

Both the SFMC-111-L2-L-D-K and SFMC-111-T2-L-D-P are active production parts from Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. The substitute part SFMC-111-T2-L-D-P offers higher inventory availability (1696 units versus 739 units), providing improved supply chain flexibility. Both parts maintain identical electrical performance specifications, mechanical dimensions, and environmental operating ranges. Selection between these parts should be based on inventory availability and procurement lead time requirements, as all functional and compliance parameters are equivalent.

Frequently Asked Questions (FAQ)

Q: Can SFMC-111-T2-L-D-P be used as a direct replacement for SFMC-111-L2-L-D-K?

A: Yes. Both parts are 22-position receptacle connectors with 0.050" pitch, surface mount termination, and identical electrical ratings. The contact material differs (Beryllium Copper versus Phosphor Bronze), but both materials deliver equivalent performance within the specified operating temperature range of -55°C to 125°C and current rating of 2.9A per contact.

Q: What is the difference between the contact materials used in these parts?

A: The SFMC-111-L2-L-D-K uses Beryllium Copper contacts, while the SFMC-111-T2-L-D-P uses Phosphor Bronze contacts. Both materials are suitable for the same electrical and mechanical applications within this connector series and maintain the same current-carrying capacity and reliability characteristics.

Q: Are both parts RoHS compliant?

A: Yes. Both the SFMC-111-L2-L-D-K and SFMC-111-T2-L-D-P are ROHS3 compliant and carry UL94 V-0 flammability certification, meeting current regulatory requirements for electronic component manufacturing.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1, which indicates unlimited shelf life without special moisture control measures during storage and handling.

Q: Are there any differences in packaging or handling between these two parts?

A: Both parts are supplied in tube packaging. Handling and storage procedures are identical for both the main part and the substitute, with no special precautions required beyond standard electronic component handling practices.

Q: Which part should I select based on availability?

A: The SFMC-111-T2-L-D-P currently has higher inventory (1696 units) compared to the SFMC-111-L2-L-D-K (739 units). If supply continuity is a priority, the substitute part offers better availability for immediate procurement needs.
