Key Parameters

Substitute Part Grouping Explanation

Substitution for the SFML-140-T1-S-D is determined by strict equivalence across the following critical parameters:

• Connector Type & Position Count: Receptacle configuration with 80 positions
• Pitch & Row Spacing: 0.050" (1.27mm) mating pitch and row spacing
• Electrical Ratings: 3.2A per contact at 250VAC minimum
• Contact Finish: Gold-plated mating surface
• Mounting & Termination: Through-hole solder termination
• Environmental Compliance: ROHS3 compliance and UL94 V-0 flammability rating
• Operating Range: -55°C to 125°C temperature specification

The substitute part SFML-140-01-S-D meets all these criteria and is therefore electrically and mechanically interchangeable with the main part number.

Parameter Comparison

Engineering Selection Recommendations

Both the SFML-140-T1-S-D and SFML-140-01-S-D are active products from Samtec Inc. with identical electrical, mechanical, and environmental specifications. Selection between these parts should be based on:

• Inventory Availability: SFML-140-01-S-D has 1104 units in stock versus 977 units for SFML-140-T1-S-D
• Supply Chain Requirements: Both parts carry ROHS3 compliance and REACH unaffected status, meeting regulatory requirements for industrial and commercial applications
• Certification Status: Both connectors meet UL94 V-0 flammability standards and operate across the full -55°C to 125°C temperature range
• Component Consolidation: Using either part interchangeably supports design flexibility and reduces single-source dependency

No additional testing or qualification is required when substituting between these parts, as they are direct equivalents within the Tiger Eye™ SFML series.

Frequently Asked Questions (FAQ)

Q: Are SFML-140-T1-S-D and SFML-140-01-S-D pin-compatible?

A: Yes. Both connectors feature identical 80-position, 0.050" (1.27mm) pitch configurations with 2-row layouts. They are mechanically and electrically interchangeable for board-to-board and cable applications.

Q: Can I use SFML-140-01-S-D as a direct replacement in existing designs?

A: Yes. The substitute part meets all electrical ratings (3.2A per contact, 250VAC), thermal specifications (-55°C to 125°C), and compliance certifications (ROHS3, UL94 V-0) of the original part. No PCB layout or schematic modifications are required.

Q: What is the difference between the part numbers SFML-140-T1-S-D and SFML-140-01-S-D?

A: Both parts share the same base product number SFML-140 and belong to the Tiger Eye™ SFML series. The alphanumeric suffixes indicate internal Samtec designations but do not reflect functional or performance differences. All specified parameters are identical.

Q: Are both parts available in the same packaging?

A: Yes. Both SFML-140-T1-S-D and SFML-140-01-S-D are supplied in tube packaging, suitable for automated assembly and manual handling.

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

A: Both connectors carry Moisture Sensitivity Level (MSL) 1, indicating unlimited shelf life without special moisture control measures. Standard component storage practices apply.

Q: What applications are these connectors suitable for?

A: The 80-position, 0.050" pitch configuration with gold contacts and 3.2A per contact rating supports high-density interconnect applications requiring reliable board-to-board or cable connections in industrial, telecommunications, and data center environments.
