SFW4R-2STRE1 FFC/FPC Connector Equivalent & Substitute Parts

Part Overview

The SFW4R-2STRE1 is a 4-position FFC/FPC connector from Amphenol ICC (FCI) designed for surface mount, right-angle applications with 0.039" (1.00mm) pitch spacing. This connector features a slide lock mechanism and zero insertion force (ZIF) design for reliable cable termination in compact electronic assemblies.

The SFW4R-2STRE1 is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this connector.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SFW4R-2STRE1 is determined by strict equivalence across the following critical parameters:

• Connector Series & Base Product: Both parts must belong to the SFW-R series (base product SFW4R)
• Position Count: 4 positions (fixed requirement)
• Pitch Specification: 0.039" (1.00mm) (fixed requirement)
• Mounting Configuration: Surface mount, right-angle orientation (fixed requirement)
• Contact Type: Contacts, top-mounted (fixed requirement)
• Termination Method: Solder termination (fixed requirement)
• Height Above Board: 0.106" (2.70mm) (fixed requirement)
• Locking Mechanism: Slide lock (fixed requirement)
• ZIF Feature: Zero insertion force design (fixed requirement)

The substitute part SFW4R-2STRE1LF maintains full equivalence across all critical mechanical and electrical parameters. The primary distinction is product status: the substitute is active and RoHS compliant, whereas the original part is obsolete and RoHS non-compliant.

Engineering Selection Recommendations

The SFW4R-2STRE1LF is the direct substitute for the obsolete SFW4R-2STRE1. Selection of the substitute part is supported by the following factors:

• Product Status: The substitute part is active and currently in production, ensuring long-term availability and supply chain continuity.
• Compliance: The SFW4R-2STRE1LF is RoHS compliant, meeting current regulatory requirements for electronic components in most jurisdictions. The original part is RoHS non-compliant.
• Mechanical Compatibility: Both parts share identical mechanical specifications, including position count, pitch, mounting configuration, height, and locking mechanism.
• Electrical Equivalence: Both parts maintain the same ZIF design and solder termination method.
• Certifications: Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4051) classifications, and both are REACH unaffected.

For applications requiring RoHS compliance or long-term supply assurance, the SFW4R-2STRE1LF is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the SFW4R-2STRE1LF be used as a direct replacement for the SFW4R-2STRE1?

A: Yes. Both parts are mechanically and electrically equivalent across all critical parameters: 4 positions, 0.039" (1.00mm) pitch, surface mount right-angle configuration, slide lock mechanism, and ZIF design. The substitute part is active and RoHS compliant.

Q: What is the primary difference between these two parts?

A: The SFW4R-2STRE1 is obsolete and RoHS non-compliant. The SFW4R-2STRE1LF is active, RoHS compliant, and available in Tape & Reel packaging. All mechanical and functional specifications are identical.

Q: Are there any packaging differences?

A: The original part packaging is not specified. The substitute part is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: What are the electrical ratings of the substitute part?

A: The SFW4R-2STRE1LF is rated for 100V maximum voltage and 1A maximum current per contact. Operating temperature range is -55°C to 105°C.

Q: Are there any regulatory or compliance considerations?

A: Both parts carry identical ECCN (EAR99) and HTSUS (8536.69.4051) classifications. The substitute part is RoHS compliant, which is required for many applications and jurisdictions. Both are REACH unaffected.
