SFM-115-01-S-D-N Equivalent & Substitute Parts

Part Overview

The SFM-115-01-S-D-N is a 30-position receptacle connector from Samtec Inc.'s Tiger Eye™ SFM series, designed for board-to-board or cable applications. This rectangular connector features 0.050" (1.27mm) pitch mating contacts with gold plating, through-hole solder termination, and push-pull fastening. The part is Active status and ROHS3 compliant, making it suitable for industrial and commercial applications requiring reliable interconnection in temperature ranges from -55°C to 125°C.

Equivalent and substitute parts are necessary when addressing supply chain constraints, design revisions requiring specific mechanical features, or inventory optimization while maintaining electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All four parts—SFM-115-01-S-D-N, SFM-115-01-S-D-A, SFM-115-01-S-D-LC, and SFM-115-01-S-D—are Active status products from Samtec Inc.'s Tiger Eye™ SFM series and maintain ROHS3 compliance. They are electrically and mechanically interchangeable for applications requiring 30-position, 0.050" pitch receptacle connectors with gold-plated contacts and through-hole solder termination.

Selection between these parts depends on mechanical feature requirements:

• SFM-115-01-S-D-N and SFM-115-01-S-D: Use when no additional mechanical guidance or locking features are required.
• SFM-115-01-S-D-A: Use when board guide alignment is necessary for assembly or mating reliability.
• SFM-115-01-S-D-LC: Use when board lock retention is required to prevent accidental disconnection.

All parts operate within -55°C to 125°C temperature range, support 3.2A per contact and 250VAC voltage rating, and are constructed from Liquid Crystal Polymer insulation material with beryllium copper contacts.

Frequently Asked Questions (FAQ)

Q: Are SFM-115-01-S-D-N and SFM-115-01-S-D electrically identical?

A: Yes. Both parts have identical electrical specifications: 30 positions, 0.050" pitch, gold-plated contacts, 3.2A per contact rating, and 250VAC voltage rating. The difference is in optional mechanical features; SFM-115-01-S-D-N has no additional features while SFM-115-01-S-D also has no additional features.

Q: What is the functional difference between SFM-115-01-S-D-A and SFM-115-01-S-D-LC?

A: SFM-115-01-S-D-A includes a Board Guide feature for alignment during mating. SFM-115-01-S-D-LC includes a Board Lock feature for retention after mating. These are distinct mechanical enhancements; a design requiring one cannot be substituted with the other without PCB layout modification.

Q: Can I substitute SFM-115-01-S-D-N with SFM-115-01-S-D-A in an existing design?

A: Substitution is possible only if the PCB layout accommodates the Board Guide feature of SFM-115-01-S-D-A. If the original design has no guide cutout, physical interference may occur. Verify PCB footprint compatibility before substitution.

Q: Are all four parts ROHS3 compliant?

A: Yes. All four parts—SFM-115-01-S-D-N, SFM-115-01-S-D-A, SFM-115-01-S-D-LC, and SFM-115-01-S-D—are ROHS3 compliant.

Q: What is the difference in Moisture Sensitivity Level between SFM-115-01-S-D-N and the other parts?

A: SFM-115-01-S-D-N is listed as Not Applicable for MSL, while SFM-115-01-S-D-A, SFM-115-01-S-D-LC, and SFM-115-01-S-D are rated MSL 1 (Unlimited). This indicates different handling or storage classifications, but all parts maintain the same operational performance and environmental specifications.

Q: Do all substitute parts have the same mated stacking heights?

A: Yes. All four parts support identical mated stacking heights: 6.02mm, 6.17mm, 7.80mm, 7.95mm, 9.58mm, 9.73mm, 11.48mm, and 11.63mm.
