SFW5R-2STE1 FFC/FPC Connector Equivalent & Substitute Parts

Part Overview

The SFW5R-2STE1 is a 5-position FFC/FPC connector manufactured by Amphenol ICC (FCI) with top-mounted contacts, 1.00mm pitch, and right-angle surface mount configuration. This part is classified as obsolete, making equivalent and substitute parts necessary for ongoing production and maintenance applications. The connector features Zero Insertion Force (ZIF) operation with slide lock retention and is designed for flexible cable termination in compact electronic assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SFW5R-2STE1 is determined by strict alignment of the following critical parameters:

Primary Compatibility Criteria:

• Number of positions: 5
• Pitch: 0.039" (1.00mm)
• Mounting type: Surface Mount, Right Angle
• Contact position: Top
• Flat flex type: FFC, FPC
• Height above board: 0.106" (2.70mm)
• Material flammability: UL94 V-0

Secondary Compatibility Criteria:

• Contact material: Phosphor Bronze
• Housing material: Polyphenylene Sulfide (PPS), Glass Filled
• Features: Zero Insertion Force (ZIF)

The substitute parts listed below meet these core electrical and mechanical parameters. Variations in termination type (solder vs. kinked pin), contact finish composition, and locking mechanisms are noted where they differ from the main part.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: SFW5R-2STE1LF

The SFW5R-2STE1LF is the direct equivalent from Amphenol ICC (FCI) and maintains identical mechanical and electrical compatibility with the obsolete SFW5R-2STE1. This part is active in production, RoHS compliant, and provides superior operating temperature range (-55°C ~ 105°C). The primary difference is termination type (kinked pin vs. solder), which requires PCB design accommodation. This is the recommended substitute for direct replacement in new designs.

Secondary Substitute: 0522070533 (Molex Easy-On 52207)

The 0522070533 provides cross-manufacturer compatibility with identical mechanical dimensions (0.106" height) and top contact configuration. It maintains solder termination matching the original part and includes slide lock retention. However, this part is obsolete. Housing material differs (polyamide vs. PPS), and operating temperature range is narrower (-40°C ~ 85°C). Use this substitute only when solder termination is mandatory and the narrower temperature range is acceptable.

Conditional Substitutes: 0527930570 and 0528520570 (Molex Easy-On Series)

These parts share the 5-position, 1.00mm pitch, and right-angle surface mount configuration but have design limitations:

• 0527930570: FPC-only (not FFC/FPC), increased height (0.122"), reduced current rating (0.5A), and narrower operating temperature (-20°C ~ 85°C). Use only when FPC-only compatibility is acceptable.
• 0528520570: Bottom contact configuration (not top), increased height (0.122"), reduced current rating (0.5A), and narrower operating temperature (-20°C ~ 80°C). Use only when bottom-mounted contacts are required by PCB layout.

Frequently Asked Questions (FAQ)

Q: Can SFW5R-2STE1LF replace SFW5R-2STE1 directly on existing PCBs?

A: Mechanical and electrical compatibility is maintained. However, the termination type differs (kinked pin vs. solder). Existing PCB designs with solder pads require modification to accommodate kinked pin termination. Consult PCB layout documentation before substitution.

Q: What is the key difference between the Amphenol and Molex substitutes?

A: The Amphenol SFW5R-2STE1LF is the same series with active production status and RoHS compliance. Molex parts (0522070533, 0527930570, 0528520570) are cross-manufacturer alternatives with variations in housing material, contact position, or height. Amphenol is preferred for direct replacement.

Q: Are 0527930570 and 0528520570 fully compatible with SFW5R-2STE1?

A: No. Both parts have design differences that limit compatibility. 0527930570 is FPC-only and has increased height. 0528520570 has bottom contacts instead of top contacts. These are conditional substitutes only when specific design requirements align with their specifications.

Q: What is the impact of RoHS compliance on substitution?

A: The original SFW5R-2STE1 is RoHS non-compliant. All active substitutes (SFW5R-2STE1LF, 0527930570, 0528520570) are RoHS compliant. If RoHS compliance is required for your application, use active substitutes. If legacy RoHS non-compliant designs must be maintained, the obsolete 0522070533 is available.

Q: How do operating temperature ranges affect part selection?

A: The SFW5R-2STE1LF provides the widest operating range (-55°C ~ 105°C), suitable for industrial and automotive applications. Molex alternatives have narrower ranges (-20°C ~ 85°C or -20°C ~ 80°C). Verify your application's temperature requirements before substitution.

Q: What is the difference between FFC and FPC compatibility?

A: FFC (Flat Flexible Cable) connectors accept both FFC and FPC cables. FPC (Flexible Printed Circuit) connectors accept FPC only. The 0527930570 is FPC-only, limiting cable options. The SFW5R-2STE1 and SFW5R-2STE1LF accept both FFC and FPC, providing greater flexibility.

Q: Can I use 0528520570 if my PCB layout requires bottom-mounted contacts?

A: Yes, if your PCB design specifically requires bottom contact configuration and the increased height (0.122" vs. 0.106") is acceptable. Verify that the reduced current rating (0.5A) and narrower operating temperature (-20°C ~ 80°C) meet your application requirements.
