Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFML-125-T2-S-D-A is determined by strict equivalence across the following critical parameters:

• Connector type (Receptacle)
• Contact type (Female Socket)
• Number of positions (50)
• Pitch - mating (0.050" / 1.27mm)
• Number of rows (2)
• Row spacing - mating (0.050" / 1.27mm)
• Mounting type (Surface Mount)
• Current rating (3.2A per Contact)
• Voltage rating (250VAC)
• Operating temperature range (-55°C ~ 125°C)
• Contact finish - mating (Gold)
• Insulation material (Liquid Crystal Polymer)
• Material flammability rating (UL94 V-0)
• RoHS compliance status (ROHS3 Compliant)

The SFML-125-02-S-D-A meets all substitution criteria and is classified as a direct equivalent within the Tiger Eye™ SFML series.

Parameter Comparison

Engineering Selection Recommendations

Both parts satisfy identical design requirements for 50-position, 0.050" pitch surface mount receptacle applications with gold-plated contacts and UL94 V-0 flammability rating.

Frequently Asked Questions (FAQ)

Q: Are SFML-125-T2-S-D-A and SFML-125-02-S-D-A electrically interchangeable?

A: Yes. Both parts share identical electrical specifications including 3.2A per contact current rating, 250VAC voltage rating, and gold-plated mating contacts with 30.0µin thickness.

Q: Do these parts have the same mechanical footprint?

A: Yes. Both connectors feature 50 positions arranged in 2 rows with 0.050" (1.27mm) pitch and row spacing, identical insulation height of 0.185" (4.70mm), and surface mount termination.

Q: Are there compliance differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, carry UL94 V-0 flammability rating, and share identical ECCN and HTSUS classifications.

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

A: Both parts belong to the same Tiger Eye™ SFML base product family (SFML-125) and are functionally equivalent. The part number suffix variation reflects internal Samtec designation but does not indicate functional or electrical differences.

Q: Can I use either part in my design without PCB layout changes?

A: Yes. Both parts are mechanically and electrically identical with matching footprints, mounting requirements, and contact configurations.

Q: What is the operating temperature range for both parts?

A: Both parts operate across -55°C to 125°C, suitable for industrial and extended temperature applications.
