SFW4R-5STE1LF Equivalent & Substitute Parts

Part Overview

The SFW4R-5STE1LF is a 4-position CIC (Compression Insulation Crimp) connector manufactured by Amphenol ICC (FCI), designed for flat flexible cable applications with 1.00mm pitch and right-angle surface mount termination. This connector features zero insertion force (ZIF) operation and kinked pin termination, rated for 1A at 100V with operating temperatures from -55°C to 105°C. The part is currently active in production with RoHS compliance and unlimited moisture sensitivity rating (MSL 1). Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit functional alternatives within specified electrical and mechanical parameters.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SFW4R-5STE1LF is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 4
• Pitch: 0.039" (1.00mm)
• Mounting Type: Surface Mount, Right Angle
• FFC/FCB Thickness: 0.30mm
• Height Above Board: 0.106" (2.70mm)
• Contact Material: Phosphor Bronze
• Features: Zero Insertion Force (ZIF)
• Voltage Rating: minimum 100V
• Current Rating: minimum 1A
• Operating Temperature Range: must encompass -55°C to 105°C or be compatible with application requirements
• Material Flammability Rating: UL94 V-0

Acceptable Variations:

• Connector/Contact Type: CIC (bottom) or FFC/FPC (top) configurations are functionally equivalent when mating with corresponding cable assemblies
• Termination Method: Kinked pin or solder termination are both acceptable for surface mount applications
• Contact Finish: Tin or gold finishes are both acceptable for the specified voltage and current ratings
• Housing Material: PPS or Polyamide (PA46) materials both meet UL94 V-0 flammability requirements
• Locking Feature: Presence or absence of slide lock does not affect electrical substitution
• Mating Cycles: Variations in cycle ratings are acceptable provided minimum requirement is met

The substitute part 0522070460 (Molex 52207 series) meets all mandatory parameters and is therefore classified as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0522070460 connector is classified as a functional equivalent to the SFW4R-5STE1LF based on matching electrical specifications, mechanical dimensions, and compliance certifications. Both parts are active products with current manufacturing status and meet UL94 V-0 flammability requirements.

Selection Considerations:

The primary distinction between these parts is the operating temperature range. The SFW4R-5STE1LF supports -55°C to 105°C operation, while the Molex substitute supports -30°C to 85°C. Applications requiring the full lower temperature range (-55°C) or upper temperature range (above 85°C) must use the Amphenol ICC part. Applications operating within -30°C to 85°C may use either part interchangeably.

Both parts feature identical pitch (1.00mm), position count (4), mounting configuration (surface mount right angle), and board height (2.70mm), ensuring mechanical compatibility with existing PCB layouts and cable assemblies designed for either connector type.

The Molex part offers enhanced mating cycle rating (30 cycles versus 10 cycles) and includes solder retention features, providing additional robustness in high-reliability applications. The substitute part's higher voltage rating (125V versus 100V) provides additional design margin for the specified 100V application.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0522070460 be used as a direct replacement for the SFW4R-5STE1LF in all applications?

A: The Molex part is mechanically and electrically compatible for applications operating within -30°C to 85°C. Applications requiring operation below -30°C or above 85°C must use the Amphenol ICC part to ensure compliance with specified operating temperature ranges.

Q: What is the difference between CIC and FFC/FPC connector types?

A: CIC (Compression Insulation Crimp) and FFC/FPC (Flat Flexible Cable/Flat Printed Cable) refer to different connector interface standards. The SFW4R-5STE1LF uses CIC contacts with bottom configuration, while the Molex 0522070460 uses FFC/FPC contacts with top configuration. Both are compatible with 1.00mm pitch flat flexible cables and provide equivalent electrical performance.

Q: Are the contact finishes (tin versus gold) interchangeable?

A: Both tin and gold contact finishes are acceptable for the specified 1A at 100V application. Gold finishes provide enhanced corrosion resistance and are typically preferred for low-signal applications or harsh environments. Tin finishes are suitable for standard industrial applications. Selection should be based on application environment and cost considerations.

Q: What does the mating cycle rating indicate?

A: Mating cycle rating specifies the number of times a connector can be mated and unmated while maintaining electrical and mechanical performance. The SFW4R-5STE1LF is rated for 10 cycles, while the Molex substitute is rated for 30 cycles. Higher cycle ratings indicate greater durability for applications requiring frequent connection and disconnection.

Q: Are both parts RoHS compliant?

A: Yes. The SFW4R-5STE1LF is RoHS Compliant, and the Molex 0522070460 is ROHS3 Compliant. Both meet current RoHS requirements for lead-free and restricted substance compliance.

Q: What is the significance of the 0.30mm FFC/FCB thickness specification?

A: The 0.30mm thickness refers to the flat flexible cable or printed circuit board thickness that these connectors are designed to accommodate. Both the main part and substitute are rated for 0.30mm thickness, ensuring mechanical compatibility with existing cable assemblies and PCB designs.
