SFW4S-2STME1 FFC/FPC Connector Equivalent & Substitute Parts

Part Overview

The SFW4S-2STME1 is a 4-position FFC/FPC vertical connector with 1.00mm pitch, designed for surface mount applications. This connector features zero insertion force (ZIF) operation, slide lock mechanism, and solder termination. The part is currently classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFW4S-2STME1 is determined by the following critical parameters:

• Number of positions: 4
• Pitch: 0.039" (1.00mm)
• Mounting type: Surface Mount
• Connector orientation: Vertical - 1 Sided
• Voltage rating: 100V minimum
• Current rating: 1A minimum
• Termination method: Solder
• Housing material: Thermoplastic, Glass Filled
• Contact material: Phosphor Bronze

The substitute part SFW4S-2STME1LF meets all these criteria. Both parts belong to the same SFW series and share identical mechanical and electrical specifications for the core connector function. The primary differences relate to product status, compliance certifications, and minor feature variations.

Parameter Comparison

Engineering Selection Recommendations

The SFW4S-2STME1LF is the direct substitute for the obsolete SFW4S-2STME1. Selection of the substitute part is supported by the following factors:

• Identical electrical and mechanical specifications for connector function
• Active product status with current manufacturing support
• RoHS compliance certification, meeting modern regulatory requirements
• Extended operating temperature range (-55°C ~ 105°C vs. -55°C ~ 85°C)
• Equivalent packaging availability (Cut Tape and Digi-Reel options)
• Higher current inventory levels (2021 pcs vs. 1065 pcs)

The SFW4S-2STME1LF maintains full functional compatibility with designs originally specified for the SFW4S-2STME1, with the added benefit of improved compliance status and extended thermal operating range.

Frequently Asked Questions (FAQ)

Q: Are SFW4S-2STME1 and SFW4S-2STME1LF mechanically interchangeable?

A: Yes. Both connectors share identical mechanical specifications including pitch (1.00mm), number of positions (4), mounting type (surface mount), and height above board (5.30mm). PCB footprints and assembly processes are identical.

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

A: The primary differences are product status (obsolete vs. active), RoHS compliance (non-compliant vs. compliant), and operating temperature range (-55°C ~ 85°C vs. -55°C ~ 105°C). Electrical and mechanical connector specifications are equivalent.

Q: Can I use SFW4S-2STME1LF in a design originally specified for SFW4S-2STME1?

A: Yes. The substitute part meets or exceeds all electrical and mechanical requirements of the original specification. The extended temperature range and improved compliance status make it suitable for direct substitution.

Q: What packaging options are available for the substitute part?

A: SFW4S-2STME1LF is available in Cut Tape (CT) and Digi-Reel packaging formats.

Q: Are there any feature differences I should be aware of?

A: The SFW4S-2STME1 includes a slide lock mechanism and solder retention features. The SFW4S-2STME1LF retains zero insertion force (ZIF) operation and equivalent electrical performance. Verify specific feature requirements against your application needs.
