SFM-106-L2-S-D-A Equivalent & Substitute Parts

Part Overview

The SFM-106-L2-S-D-A is a 12-position receptacle connector from Samtec Inc.'s Tiger Eye™ SFM series, designed for surface mount board-to-board or cable applications. This connector features 0.050" (1.27mm) pitch mating with gold-plated female socket contacts rated for 3.2A per contact at 250VAC. The part is active in production with ROHS3 compliance and UL94 V-0 flammability rating. Alternative models within the same series may be required due to inventory availability, application-specific stacking height requirements, or procurement lead time considerations.

Substitute Part Grouping Explanation

The SFM-106-L2-S-D-A can be substituted with SFM-106-02-S-D-A based on the following substitution criteria:

Both parts share identical electrical and mechanical specifications:

• Same connector type (12-position receptacle)
• Identical pitch and row spacing (0.050" / 1.27mm)
• Matching contact configuration (female socket, gold-plated mating surface)
• Equivalent current and voltage ratings (3.2A per contact, 250VAC)
• Same operating temperature range (-55°C ~ 125°C)
• Identical material specifications (Beryllium Copper contacts, LCP insulation)
• Matching compliance certifications (ROHS3, UL94 V-0, MSL 1)
• Same fastening type (Push-Pull) and mounting method (Surface Mount)

The substitution is valid across all mated stacking heights (6.15mm through 11.76mm) and both parts maintain identical board guide features and solder termination specifications.

Parameter Comparison

Engineering Selection Recommendations

Both SFM-106-L2-S-D-A and SFM-106-02-S-D-A are active production parts with identical electrical, mechanical, and compliance specifications. Selection between these parts should be based on:

• Inventory availability: SFM-106-02-S-D-A currently has higher stock (1534 pcs vs. 677 pcs)
• Procurement lead times and supply chain requirements
• Application-specific stacking height requirements, as both parts support the full range of mated stacking heights (6.15mm through 11.76mm)

Both parts maintain ROHS3 compliance, UL94 V-0 flammability certification, and identical performance characteristics across all specified operating conditions.

Frequently Asked Questions (FAQ)

Q: Are SFM-106-L2-S-D-A and SFM-106-02-S-D-A electrically interchangeable?

A: Yes. Both parts have identical electrical specifications including 3.2A per contact current rating, 250VAC voltage rating, and gold-plated contact finish with 30.0µin (0.76µm) thickness.

Q: Do these connectors have the same physical footprint?

A: Yes. Both parts share identical mechanical specifications: 12-position receptacle configuration, 0.050" (1.27mm) pitch, 2-row layout with 0.050" row spacing, and 0.185" (4.70mm) insulation height. They support the same mated stacking heights.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, carry UL94 V-0 flammability rating, have MSL 1 (Unlimited) moisture sensitivity level, and share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: Can I use these connectors in high-temperature applications?

A: Both parts are rated for -55°C to 125°C operating temperature range, suitable for standard industrial and commercial applications within this thermal envelope.

Q: What is the difference between the part numbers SFM-106-L2-S-D-A and SFM-106-02-S-D-A?

A: The part numbers differ in the position code (L2 vs. 02), but all other specifications are identical. This variation does not affect electrical performance, mechanical compatibility, or compliance certifications.

Q: Are these parts suitable for board-to-board applications?

A: Yes. Both connectors are designed for board-to-board or cable applications with surface mount termination and push-pull fastening type.
