SFW10S-2STME1 FFC/FPC Connector Equivalent & Substitute Parts

Part Overview

The SFW10S-2STME1 is a 10-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 for flat flexible cable assemblies. The part is currently classified as obsolete, which necessitates identification of active equivalent alternatives to maintain design continuity and ensure supply chain availability for new production and repair applications.

Engineering Selection Recommendations

The SFW10S-2STME1LF is a direct functional equivalent to the obsolete SFW10S-2STME1. Selection of the substitute part is based on the following engineering criteria:

Product Status: The SFW10S-2STME1LF maintains active manufacturing status, ensuring long-term supply chain availability and consistent quality control compared to the obsolete main part.

Electrical Compatibility: All critical electrical parameters—voltage rating (100V), current rating (1A), and contact material (phosphor bronze)—are identical. The extended operating temperature range (-55°C ~ 105°C) of the substitute provides additional thermal margin beyond the main part's specification (-55°C ~ 85°C).

Mechanical Compatibility: Connector geometry, pitch (1.00mm), position count (10), mounting type (surface mount), and height above board (5.30mm) are identical. The substitute accommodates FFC/FCB thickness of 0.33mm, which falls within the main part's acceptable range (0.30mm, 0.33mm).

Compliance Advantage: The SFW10S-2STME1LF is RoHS compliant, whereas the main part is RoHS non-compliant. This represents a compliance improvement for new designs and applications subject to RoHS regulations.

Packaging Consideration: The substitute is supplied in Tape & Reel (TR) format, suitable for automated assembly processes. The main part was supplied in bulk format. Both packaging formats are compatible with standard PCB assembly equipment.

Frequently Asked Questions (FAQ)

Q: Can SFW10S-2STME1LF be used as a direct replacement for SFW10S-2STME1 in existing designs?

A: Yes. The SFW10S-2STME1LF is mechanically and electrically compatible with the SFW10S-2STME1. All critical parameters—position count, pitch, voltage rating, current rating, and mounting configuration—are identical. The substitute part meets or exceeds the performance specifications of the main part.

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

A: The "LF" suffix in SFW10S-2STME1LF indicates RoHS compliance and Tape & Reel packaging. The main part (SFW10S-2STME1) is RoHS non-compliant and supplied in bulk format. Both parts are from the same SFW series and share identical connector geometry and electrical ratings.

Q: Are there any thermal performance differences?

A: The SFW10S-2STME1LF has an extended operating temperature range (-55°C ~ 105°C) compared to the main part (-55°C ~ 85°C). This provides additional thermal margin and is fully compatible with applications designed for the main part's temperature range.

Q: Does the absence of "Solder Retention" feature in the substitute part affect compatibility?

A: No. Solder retention is a manufacturing feature that aids in assembly process control. Its absence in the substitute part does not affect electrical or mechanical compatibility. Both parts feature zero insertion force (ZIF) operation and are suitable for the same applications.

Q: What packaging format should be specified for new production orders?

A: The SFW10S-2STME1LF is supplied in Tape & Reel (TR) format, which is standard for automated PCB assembly. This format is compatible with pick-and-place equipment and provides better handling and traceability compared to bulk packaging.

Q: Is the contact finish difference (Tin Alloy vs. Tin) significant?

A: No. Both tin alloy and tin finishes provide equivalent electrical performance and corrosion resistance for this connector application. The contact material (phosphor bronze) is identical in both parts, ensuring consistent contact resistance and durability.
