Key Parameters

Substitute Part Grouping Explanation

The SFML-125-T1-S-D qualifies as a direct substitute for the SFML-125-01-S-D based on identical electrical and mechanical parameters. Both connectors share the same base product number (SFML-125) and maintain matching specifications across all critical substitution criteria: 50-position configuration, 0.050" (1.27mm) pitch, two-row layout, through-hole mounting, gold mating contact finish, 3.2A per contact current rating, and 250VAC voltage rating. Operating temperature range, insulation material (Liquid Crystal Polymer), flammability rating (UL94 V-0), and compliance certifications (ROHS3, REACH Unaffected) are identical. The substitution is valid for applications requiring equivalent electrical performance and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the SFML-125-01-S-D and SFML-125-T1-S-D maintain active product status with full compliance to ROHS3 and REACH regulations. Selection between these parts should be based on inventory availability and supply chain requirements. The SFML-125-01-S-D currently has 769 units in stock, while the SFML-125-T1-S-D has 701 units available. Both connectors carry identical electrical ratings, mechanical specifications, and environmental certifications, making them functionally interchangeable for all applications within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can SFML-125-T1-S-D replace SFML-125-01-S-D in existing designs? A: Yes. Both connectors are electrically and mechanically identical across all specified parameters, including pitch, contact count, current rating, voltage rating, and operating temperature range. Direct substitution is valid without design modification.

Q: What determines compatibility between these two part numbers? A: Compatibility is established through matching electrical parameters (3.2A per contact, 250VAC), mechanical configuration (50 positions, 0.050" pitch, 2 rows), mounting type (through hole), contact finish (gold), and environmental ratings (UL94 V-0, -55°C to 125°C operating range).

Q: Are there any packaging or MSL differences between these parts? A: No. Both parts are supplied in tube packaging with identical Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no special moisture handling requirements.

Q: Which part should be selected for new designs? A: Either part is suitable for new designs. Selection may be based on current inventory levels or supplier availability. The SFML-125-01-S-D currently has higher stock availability at 769 units.
