Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFM-125-02-L-D-K is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Position count (50 positions)
• Mating pitch (0.050" / 1.27mm)
• Row configuration (2 rows with 0.050" spacing)
• Mounting method (Surface Mount)
• Contact finish specification (Gold mating surface)
• Electrical ratings (3.2A per contact, 250VAC minimum)
• Operating temperature range (-55°C ~ 125°C)
• Compliance certifications (UL94 V-0, RoHS3)

The SFM-125-02-L-D-P qualifies as a direct substitute based on identical alignment across all these parameters. Both parts belong to the Tiger Eye™ SFM series and share the same base product number (SFM-125), confirming mechanical and electrical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SFM-125-02-L-D-K and SFM-125-02-L-D-P maintain Active product status within the Tiger Eye™ SFM series, ensuring ongoing manufacturer support and supply availability. Both parts carry identical RoHS3 compliance and UL94 V-0 flammability certification, meeting regulatory requirements for industrial and commercial applications. The MSL 1 rating for both components indicates unlimited shelf life under standard storage conditions, eliminating moisture-related constraints during procurement and assembly planning.

Selection between these parts should be based on current inventory availability and lead time requirements, as electrical performance, mechanical compatibility, and compliance certifications are equivalent.

Frequently Asked Questions (FAQ)

Q: Are SFM-125-02-L-D-K and SFM-125-02-L-D-P mechanically interchangeable?

A: Yes. Both connectors share identical mating pitch (0.050"), row configuration (2 rows with 0.050" spacing), insulation height (0.185"), and surface mount footprint. They are mechanically interchangeable in board-to-board and cable applications.

Q: Do these parts have the same electrical ratings?

A: Yes. Both connectors are rated for 3.2A per contact and 250VAC, with identical operating temperature range (-55°C ~ 125°C) and contact finish specifications (gold mating surface, 10.0µin thickness).

Q: What is the difference between these two part numbers?

A: The provided specifications indicate no functional or electrical differences between SFM-125-02-L-D-K and SFM-125-02-L-D-P. Both are 50-position receptacle connectors from the same Tiger Eye™ SFM series with identical performance parameters.

Q: Are both parts RoHS3 compliant?

A: Yes. Both SFM-125-02-L-D-K and SFM-125-02-L-D-P carry ROHS3 compliance certification and meet UL94 V-0 flammability requirements.

Q: What is the MSL rating for these connectors?

A: Both parts have MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints and unlimited shelf life under standard storage conditions.

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

A: Both connectors support the operating temperature range of -55°C ~ 125°C. Applications requiring operation outside this range require alternative component selection.
