Substitute Part Grouping Explanation

Substitute parts for the SFML-110-L2-S-D-A are identified within the Tiger Eye™ SFML series based on strict electrical and mechanical parameter equivalence. The substitution criteria are:

• Identical connector type (Receptacle)
• Identical contact type (Female Socket)
• Identical number of positions (20)
• Identical pitch - mating (0.050" / 1.27mm)
• Identical number of rows (2)
• Identical row spacing - mating (0.050" / 1.27mm)
• Identical mounting type (Surface Mount)
• Identical termination (Solder)
• Identical contact finish - mating (Gold, 30.0µin / 0.76µm)
• Identical current rating (3.2A per Contact)
• Identical voltage rating (250VAC)
• Identical operating temperature range (-55°C ~ 125°C)
• Identical material flammability rating (UL94 V-0)
• Identical insulation material (Liquid Crystal Polymer / LCP)
• Identical contact shape (Square)
• Identical RoHS compliance (ROHS3 Compliant)
• Identical MSL rating (1 / Unlimited)

The identified substitutes differ only in fastening type designation within the part number structure, which does not affect the core electrical or mechanical performance characteristics.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SFML-110-L2-S-D-A, SFML-110-02-S-D-A, and SFML-110-T2-S-D-A—maintain Active product status and are ROHS3 compliant. Each part carries identical electrical specifications, mechanical dimensions, and environmental ratings. Selection between these parts is based on inventory availability and supply chain requirements rather than technical performance differences.

SFML-110-T2-S-D-A currently maintains the highest inventory level at 1144 pieces. SFML-110-L2-S-D-A provides 1072 pieces in stock. SFML-110-02-S-D-A offers 741 pieces. All parts are suitable for applications requiring 20-position, 0.050" pitch surface mount receptacle connectors with gold-plated contacts, 3.2A per contact current capacity, and 250VAC voltage rating across the -55°C to 125°C operating temperature range.

Frequently Asked Questions (FAQ)

Q: Are SFML-110-L2-S-D-A, SFML-110-02-S-D-A, and SFML-110-T2-S-D-A electrically interchangeable?

A: Yes. All three parts share identical electrical specifications including 3.2A per contact current rating, 250VAC voltage rating, gold contact finish at 30.0µin (0.76µm) thickness, and operating temperature range of -55°C to 125°C.

Q: Are these parts mechanically interchangeable?

A: Yes. All three parts feature identical mechanical parameters: 20 positions, 0.050" (1.27mm) mating pitch, 2-row configuration with 0.050" (1.27mm) row spacing, surface mount termination, 0.185" (4.70mm) insulation height, and locking ramp fastening type.

Q: What is the difference between these part numbers?

A: The part numbers differ in their fastening type designation characters, but all three parts specify identical locking ramp fastening. The differences are nomenclature-based within Samtec's part numbering system and do not reflect functional or performance variations.

Q: Are all three parts RoHS compliant?

A: Yes. SFML-110-L2-S-D-A, SFML-110-02-S-D-A, and SFML-110-T2-S-D-A are all ROHS3 compliant with MSL rating of 1 (Unlimited).

Q: Which part should I select based on availability?

A: Selection should be based on current inventory levels and supply chain lead times. SFML-110-T2-S-D-A currently maintains the highest stock level at 1144 pieces, followed by SFML-110-L2-S-D-A at 1072 pieces, and SFML-110-02-S-D-A at 741 pieces.

Q: Can these connectors be used in high-temperature applications?

A: Yes. All three parts are rated for operating temperatures from -55°C to 125°C and carry UL94 V-0 material flammability rating, suitable for industrial and demanding thermal environments.

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

A: Yes. All three parts are classified as board-to-board or cable style receptacle connectors with surface mount termination and board guide features.
