SFW20S-2STME1 FFC/FPC Connector Equivalent & Substitute Parts

Part Overview

The SFW20S-2STME1 is a 20-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 obsolete, making identification of compatible substitute components essential for ongoing production support and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFW20S-2STME1 is determined by the following critical parameters:

• Position Count: 20 positions (fixed requirement)
• Pitch: 0.039" (1.00mm) (fixed requirement)
• Mounting Type: Surface Mount (fixed requirement)
• Connector Orientation: Vertical - 1 Sided (fixed requirement)
• Voltage Rating: 100V minimum (fixed requirement)
• Current Rating: 1A minimum (fixed requirement)
• Termination Method: Solder (fixed requirement)
• FFC/FPC Thickness Compatibility: 0.30mm, 0.33mm acceptable
• Height Above Board: 0.209" (5.30mm) (fixed requirement)
• Material Flammability: UL94 V-0 (fixed requirement)
• Mating Cycles: 20 minimum (fixed requirement)

The SFW20S-2STME1LF qualifies as a direct substitute based on matching all critical electrical, mechanical, and dimensional parameters while maintaining compatibility with the same FFC/FPC cable specifications.

Parameter Comparison

Engineering Selection Recommendations

The SFW20S-2STME1LF is the qualified substitute for the obsolete SFW20S-2STME1 based on the following factors:

Electrical Compatibility: Both parts maintain identical voltage (100V) and current (1A) ratings, ensuring equivalent electrical performance in circuit applications.

Mechanical Compatibility: Pitch (1.00mm), position count (20), mounting type (surface mount), and height above board (5.30mm) are identical, confirming direct PCB footprint compatibility.

Environmental Compliance: The substitute part is RoHS Compliant and REACH Affected, meeting current regulatory requirements. The main part is RoHS non-compliant, making the substitute the appropriate choice for new designs and ongoing production requiring environmental compliance.

Operational Range: The substitute extends the upper operating temperature limit to 105°C compared to the main part's 85°C maximum, providing enhanced thermal performance without compromising lower temperature operation.

Cable Compatibility: Both parts accept 0.33mm FFC/FPC thickness. The substitute's single thickness specification (0.33mm) is compatible with the main part's dual thickness range (0.30mm, 0.33mm) at the 0.33mm overlap point.

Product Availability: The substitute is in active production status with 4588 units in stock, ensuring supply continuity compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the SFW20S-2STME1LF be used as a direct replacement for the SFW20S-2STME1 on existing PCBs?

A: Yes. The SFW20S-2STME1LF is a direct substitute with identical footprint dimensions, pitch, position count, and mounting type. No PCB redesign is required.

Q: What is the difference between the locking features of these two parts?

A: The main part (SFW20S-2STME1) includes a slide lock mechanism. The substitute (SFW20S-2STME1LF) does not specify a locking feature. Both parts feature zero insertion force (ZIF) operation. Verify cable retention requirements for your application.

Q: Are there FFC/FPC thickness compatibility concerns?

A: The main part accepts 0.30mm and 0.33mm thickness cables. The substitute accepts 0.33mm thickness. If your design uses 0.30mm cable, the substitute is not compatible. For 0.33mm cable applications, both parts are compatible.

Q: Does the extended operating temperature range of the substitute affect compatibility?

A: No. The substitute's extended range (-55°C to 105°C) encompasses the main part's range (-55°C to 85°C). The substitute maintains full compatibility for all temperature conditions within the original specification.

Q: What are the RoHS compliance implications?

A: The main part is RoHS non-compliant. The substitute is RoHS Compliant. For new designs, production runs requiring environmental compliance, or markets with RoHS mandates, the substitute is the required choice.

Q: Is the substitute suitable for high-reliability applications?

A: Both parts maintain identical mating cycle ratings (20 cycles) and material flammability ratings (UL94 V-0). The substitute's active production status and RoHS compliance make it suitable for applications requiring current environmental and regulatory standards.
