Key Parameters

Substitute Part Grouping Explanation

Substitution for the SFM-110-L2-L-D-K-TR is determined by equivalence across the following critical parameters: connector type (receptacle), contact type (female socket), number of positions (20), mating pitch (0.050"), row configuration (2 rows at 0.050" spacing), mounting type (surface mount), termination method (solder), contact finish (gold), electrical ratings (3.2A per contact, 250VAC), operating temperature range (-55°C to 125°C), and material compliance (UL94 V-0, ROHS3). The identified substitutes maintain identical electrical and mechanical specifications while differing only in packaging format or internal part numbering variants within the SFM-110 base product family.

Parameter Comparison

Engineering Selection Recommendations

All three parts—SFM-110-L2-L-D-K-TR, SFM-110-02-L-D-K-TR, and SFM-110-02-L-D-P-TR—are Active status products from Samtec Inc. and maintain full ROHS3 compliance and UL94 V-0 material certification. Selection between these parts is based on packaging requirements and inventory availability rather than electrical or mechanical performance differences. The SFM-110-L2-L-D-K-TR and SFM-110-02-L-D-K-TR are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes. The SFM-110-02-L-D-P-TR is supplied in Cut Tape (CT) packaging, appropriate for lower-volume or manual assembly applications. All parts carry MSL 1 (Unlimited) moisture sensitivity rating, eliminating bake-out requirements for standard storage and handling conditions.

Frequently Asked Questions (FAQ)

Q: Can SFM-110-02-L-D-K-TR and SFM-110-02-L-D-P-TR be used interchangeably with SFM-110-L2-L-D-K-TR?

A: Yes. All three parts are electrically and mechanically equivalent. They share identical connector specifications, contact ratings, operating temperature range, and compliance certifications. Differences exist only in packaging format (Tape & Reel versus Cut Tape).

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) packaging?

A: Tape & Reel packaging is designed for high-speed automated pick-and-place assembly and is the standard for production runs. Cut Tape packaging is supplied in smaller quantities on individual tape segments, suitable for prototyping, low-volume builds, or manual assembly workflows.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. SFM-110-L2-L-D-K-TR, SFM-110-02-L-D-K-TR, and SFM-110-02-L-D-P-TR are all ROHS3 compliant and carry UL94 V-0 material flammability certification.

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

A: All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity. Standard storage and handling conditions do not require special bake-out procedures.

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

A: Yes. All parts are rated for continuous operation from -55°C to 125°C, supporting industrial and automotive temperature ranges.

Q: What is the current and voltage rating for each contact?

A: Each contact is rated for 3.2A at 250VAC across all three part numbers.
