Substitute Part Grouping Explanation

Substitution eligibility for the SFC-125-T2-L-D-TR is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle with female socket contacts
• Position Count & Pitch: 50 positions at 0.050" (1.27mm) mating pitch with 2-row configuration
• Electrical Ratings: 3.1A per contact at 350VAC minimum
• Mounting & Termination: Surface mount with solder termination
• Environmental Compliance: ROHS3 compliance and MSL 1 rating
• Operating Range: -55°C to 125°C temperature specification
• Contact Material & Finish: Phosphor bronze with gold mating surface (10.0µin thickness)

The substitute part SFC-125-T2-L-D-A-K-TR maintains full equivalence across all critical electrical and mechanical parameters while offering additional features including board guide and pick-and-place capability.

Parameter Comparison

Engineering Selection Recommendations

Both the SFC-125-T2-L-D-TR and SFC-125-T2-L-D-A-K-TR are Active status products with identical ROHS3 compliance and EAR99 export classification. They share equivalent electrical performance, mechanical dimensions, and environmental ratings.

The SFC-125-T2-L-D-A-K-TR offers board guide and pick-and-place features, which provide manufacturing process advantages without altering electrical or mechanical compatibility. Selection between these parts should be based on assembly process requirements and available inventory.

Frequently Asked Questions (FAQ)

Q: Can SFC-125-T2-L-D-A-K-TR be used as a direct replacement for SFC-125-T2-L-D-TR?

A: Yes. Both connectors maintain identical electrical ratings (3.1A per contact, 350VAC), mechanical pitch (0.050"), position count (50), and operating temperature range (-55°C to 125°C). The substitute part includes board guide and pick-and-place features that do not affect electrical or mechanical compatibility.

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in connector type (receptacle), position count (50), mating pitch (0.050"), row configuration (2 rows), contact type (female socket), current rating (3.1A per contact), voltage rating (350VAC), operating temperature range (-55°C to 125°C), and compliance certifications (ROHS3, MSL 1).

Q: Are there differences in packaging between these parts?

A: Both parts are supplied in Tape & Reel (TR) packaging. Inventory levels differ, with SFC-125-T2-L-D-A-K-TR offering higher stock availability (3098 pcs vs. 737 pcs).

Q: Do these connectors require any special handling or storage considerations?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity limitations. Standard ESD precautions for surface mount components apply.

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

A: The primary difference is the inclusion of board guide and pick-and-place features in the SFC-125-T2-L-D-A-K-TR variant. These features enhance manufacturing efficiency without modifying electrical performance or mating characteristics.
