Key Parameters

Substitute Part Grouping Explanation

The SFMC-115-03-S-D-P is identified as a direct substitute based on the following critical parameters that determine interchangeability:

• Connector type, contact type, and style (Receptacle, Female Socket, Board to Board or Cable)
• Position count and arrangement (30 positions, 2 rows)
• Mating pitch and row spacing (0.050" / 1.27mm)
• Mounting method and termination (Through Hole, Solder)
• Contact material and finish specifications (Beryllium Copper, Gold mating finish)
• Electrical ratings (2.9A per contact)
• Environmental specifications (Operating temperature -55°C ~ 125°C, UL94 V-0)
• Regulatory compliance (ROHS3 Compliant)

The substitute part shares the same base product number (SFMC-115) and series designation (Tiger Eye™ SFMC), confirming mechanical and electrical compatibility. The primary distinction is the addition of Pick and Place features in the substitute variant, which does not affect core connector functionality or pin compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SFMC-115-03-S-D and SFMC-115-03-S-D-P are active production parts with full ROHS3 compliance and UL94 V-0 material certification. Selection between these parts should be based on manufacturing process requirements and inventory availability.

The SFMC-115-03-S-D-P includes Pick and Place features, making it suitable for automated assembly processes. The standard SFMC-115-03-S-D is appropriate for manual assembly or applications where Pick and Place optimization is not required. Both parts maintain identical electrical performance, mechanical dimensions, and environmental ratings.

Inventory considerations: SFMC-115-03-S-D-P has higher stock availability (1225 units) compared to SFMC-115-03-S-D (837 units), which may influence sourcing decisions for high-volume production.

Frequently Asked Questions (FAQ)

Q: Are SFMC-115-03-S-D and SFMC-115-03-S-D-P pin-compatible?

A: Yes. Both parts are 30-position receptacles with identical pitch (0.050"), row spacing, contact arrangement, and electrical ratings. They are mechanically and electrically interchangeable.
