SFW4S-2STE1 Equivalent & Substitute Parts

Part Overview

The SFW4S-2STE1 is a 4-position FFC/FPC connector contact assembly manufactured by Amphenol ICC (FCI). This surface mount component features vertical orientation with 1.00mm pitch spacing and is designed for flat flexible cable applications. The part is currently active in production with 1033 units in stock. Substitute parts are identified when equivalent electrical and mechanical parameters are maintained within the allowed specifications for this connector category, enabling design flexibility and supply chain optimization.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SFW4S-2STE1 is determined by strict equivalence across the following critical parameters:

• Electrical Compatibility: Voltage rating (100V), current rating (1A), and material flammability rating (UL94 V-0) must be maintained
• Mechanical Compatibility: Number of positions (4), pitch spacing (1.00mm), mounting type (surface mount), and connector orientation (vertical - 1 sided) must be identical
• Physical Dimensions: Height above board (5.30mm) and housing material (thermoplastic, glass filled) must match
• Functional Features: Zero insertion force (ZIF) capability and solder termination must be preserved
• Series Consistency: Parts must belong to the SFW series

The SFW4S-2STE1LF qualifies as a direct substitute based on these parameters. Variations in FFC/FCB thickness tolerance, locking feature presence, cable end type, contact finish specification, actuator color, and RoHS compliance status do not preclude substitution when the core electrical and mechanical parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

Both the SFW4S-2STE1 and SFW4S-2STE1LF are active production parts from Amphenol ICC (FCI) and maintain equivalent core electrical and mechanical specifications. The SFW4S-2STE1LF offers an extended operating temperature range (-55°C ~ 105°C versus -55°C ~ 85°C) and RoHS compliance status, making it suitable for applications requiring higher temperature performance or regulatory compliance with RoHS directives. Selection between these parts should be based on specific application temperature requirements and compliance mandates rather than functional compatibility, as both parts satisfy the same connector interface specifications.

Frequently Asked Questions (FAQ)

Q: Can SFW4S-2STE1LF be used as a direct replacement for SFW4S-2STE1?

A: Yes. Both parts maintain identical electrical ratings (100V, 1A), mechanical configuration (4 positions, 1.00mm pitch, surface mount), and functional features (ZIF, solder termination). The parts are mechanically and electrically interchangeable within the specified parameters.

Q: What is the difference in operating temperature range between these parts?

A: The SFW4S-2STE1 operates from -55°C to 85°C, while the SFW4S-2STE1LF extends to 105°C. Selection depends on the thermal environment of the application.

Q: Does RoHS compliance affect substitution eligibility?

A: RoHS compliance status does not affect electrical or mechanical substitution eligibility. The SFW4S-2STE1LF is RoHS compliant while the SFW4S-2STE1 is non-compliant. Selection should align with product regulatory requirements.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts share identical height above board (5.30mm), pitch spacing (1.00mm), and mounting footprint specifications.

Q: What determines whether a part qualifies as a substitute?

A: Substitution is determined by equivalence in number of positions, pitch spacing, voltage rating, current rating, mounting type, connector orientation, flammability rating, and functional features (ZIF capability). Variations in optional features such as locking mechanisms or cable end types do not preclude substitution.
