Key Parameters

Substitute Part Grouping Explanation

Substitution of the SFM-108-02-S-D is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Receptacle configuration with 16 positions
• Pitch & Row Spacing: 0.050" (1.27mm) mating pitch and row spacing for mechanical interchangeability
• Mounting Technology: Surface mount termination with solder attachment
• Contact System: Female socket contacts with gold mating finish (30.0µin thickness)
• Electrical Performance: 3.2A per contact at 250VAC rating
• Environmental Compliance: UL94 V-0 flammability rating, ROHS3 compliance, MSL 1 rating
• Series Compatibility: Tiger Eye™ SFM series designation

The substitute part SFM-108-02-S-D-A maintains full equivalence across all critical parameters while offering alternative inventory availability.

Parameter Comparison

Engineering Selection Recommendations

Both SFM-108-02-S-D and SFM-108-02-S-D-A are active production parts from Samtec Inc. with full ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on the following criteria:

SFM-108-02-S-D: Select this part when standard receptacle functionality without additional mechanical guidance is required. Current inventory of 722 units supports immediate availability for standard applications.

SFM-108-02-S-D-A: Select this part when board guide features are beneficial for connector alignment and mating reliability. Higher inventory level of 990 units provides enhanced supply chain flexibility. The board guide feature does not alter electrical or core mechanical compatibility.

Both parts share identical electrical ratings (3.2A per contact, 250VAC), operating temperature range (-55°C ~ 125°C), contact geometry, and termination specifications. The primary distinction is the presence of a board guide feature in the SFM-108-02-S-D-A variant, which enhances mechanical positioning without affecting substitution eligibility.

Frequently Asked Questions (FAQ)

Q: Are SFM-108-02-S-D and SFM-108-02-S-D-A electrically interchangeable?

A: Yes. Both parts maintain identical current ratings (3.2A per contact), voltage ratings (250VAC), contact materials (beryllium copper with gold mating finish), and operating temperature ranges (-55°C ~ 125°C). Electrical performance is equivalent.

Q: What is the functional difference between these two parts?

A: The SFM-108-02-S-D-A includes a board guide feature for enhanced connector alignment during mating. The SFM-108-02-S-D provides standard receptacle functionality without this guide. Both maintain identical pitch (0.050"), row spacing (0.050"), and contact configuration (16 positions, 2 rows).

Q: Can I use SFM-108-02-S-D-A as a direct replacement for SFM-108-02-S-D in existing designs?

A: Yes. The board guide feature in SFM-108-02-S-D-A is a mechanical enhancement that does not compromise compatibility with mating connectors designed for the standard SFM-108-02-S-D. PCB footprints and electrical connections remain identical.

Q: Are both parts RoHS compliant?

A: Yes. Both SFM-108-02-S-D and SFM-108-02-S-D-A are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level) rating.

Q: What are the mated stacking heights for these connectors?

A: Both parts support identical mated stacking heights: 6.15mm, 6.30mm, 7.92mm, 8.08mm, 9.70mm, 9.86mm, 11.61mm, and 11.76mm, depending on mating connector configuration.

Q: Which part should I select for new designs?

A: Selection depends on design requirements. If board guide alignment is beneficial for your application, SFM-108-02-S-D-A is recommended. For standard applications without specific alignment requirements, either part is suitable. Inventory availability (990 units for SFM-108-02-S-D-A versus 722 units for SFM-108-02-S-D) may also influence selection for high-volume production.
