Substitute Part Grouping Explanation

Substitute parts for the SFM-110-L2-L-D-TR are qualified based on the following criteria:

Electrical Equivalence: All substitute parts maintain identical electrical specifications including 20-position configuration, 0.050" (1.27mm) pitch, 3.2A per contact current rating, and 250VAC voltage rating.

Mechanical Compatibility: All substitutes share the same connector type (receptacle), contact type (female socket), mounting method (surface mount), mating interface geometry (0.050" pitch, 2-row configuration), and insulation material (Liquid Crystal Polymer).

Environmental & Compliance: All substitutes operate across the same temperature range (-55°C ~ 125°C), maintain UL94 V-0 flammability rating, ROHS3 compliance, and MSL 1 moisture sensitivity level.

Variable Parameters: Substitutes differ in packaging format (Tape & Reel vs. Cut Tape) and optional features (Board Guide, Board Lock, Pick and Place capability). These variations do not affect electrical or mechanical interface compatibility.

Engineering Selection Recommendations

All substitute parts maintain full electrical and mechanical compatibility with the SFM-110-L2-L-D-TR. Selection between the main part and substitutes depends on procurement and assembly requirements:

SFM-110-02-L-D-A-K-TR offers the highest inventory availability (11424 units) in Tape & Reel packaging with Board Guide and Pick and Place features, suitable for high-volume automated assembly operations.

SFM-110-02-L-D-A-P-TR provides equivalent features in Cut Tape packaging (6567 units), appropriate for lower-volume or mixed-component procurement scenarios.

SFM-110-02-L-D-K-TR delivers Tape & Reel packaging with Pick and Place capability (2133 units) without Board Guide features.

SFM-110-02-L-D-LC-K-TR includes Board Lock feature in Cut Tape format (1850 units) for applications requiring enhanced mechanical retention.

SFM-110-02-L-D-P-TR provides Cut Tape packaging with Pick and Place capability (1691 units) for flexible procurement options.

All parts maintain ROHS3 compliance, UL94 V-0 flammability rating, and MSL 1 moisture sensitivity level. No additional testing or validation is required for electrical or thermal performance equivalence.

Frequently Asked Questions (FAQ)

Q: Can SFM-110-02-L-D-A-K-TR be used as a direct replacement for SFM-110-L2-L-D-TR?

A: Yes. Both parts share identical electrical specifications (20 positions, 0.050" pitch, 3.2A per contact, 250VAC), mechanical interface geometry, and environmental ratings. The substitute includes Board Guide and Pick and Place features that do not affect mating compatibility.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel packaging supplies components on continuous carrier tape wound on reels, optimized for high-speed automated pick-and-place assembly. Cut Tape packaging provides components on tape segments cut to specified lengths, suitable for lower-volume orders or mixed-component kits. Electrical and mechanical specifications remain identical.

Q: Does the Board Guide feature affect connector compatibility?

A: No. The Board Guide is a mechanical assembly aid that improves placement accuracy during manufacturing. It does not alter the electrical interface, mating geometry, or contact specifications.

Q: What is the Board Lock feature in SFM-110-02-L-D-LC-K-TR?

A: Board Lock provides enhanced mechanical retention between mated connectors. This feature does not affect electrical performance or mating interface compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and UL94 V-0 flammability rating, identical to the main part.

Q: Can I mix packaging formats in the same assembly?

A: Yes. Tape & Reel and Cut Tape variants of the same part number are electrically and mechanically equivalent. Packaging format selection depends on procurement and assembly process requirements only.
