SLW4S-1C7 FFC/FPC Connector Equivalent & Substitute Parts

Part Overview

The SLW4S-1C7 is a 4-position FFC/FPC vertical connector with 1.00mm pitch, designed for through-hole PCB mounting. This connector features Zero Insertion Force (ZIF) operation with a slide lock mechanism and is rated for 100V and 1A per contact. The part is classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution for the SLW4S-1C7 is determined by strict equivalence across the following critical parameters:

• Connector Position Count: 4 positions (fixed requirement)
• Pitch Specification: 0.039" (1.00mm) (fixed requirement)
• Mounting Configuration: Through hole, vertical orientation, 1-sided contacts (fixed requirement)
• Electrical Ratings: Minimum 100V voltage rating and 1A current rating per contact (fixed requirement)
• Mechanical Interface: Height above board 0.217" (5.50mm), slide lock mechanism, ZIF operation (fixed requirement)
• Material Compliance: UL94 V-0 flammability rating, phosphor bronze contacts with tin finish (fixed requirement)

The substitute part SLW4S-1C7LF maintains full compatibility across all critical parameters while offering improved RoHS compliance status and expanded inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The SLW4S-1C7LF is a direct functional equivalent to the SLW4S-1C7 across all critical electrical and mechanical parameters. The primary distinction is RoHS compliance status: the SLW4S-1C7LF is RoHS compliant, whereas the original part is non-compliant. Both parts maintain identical electrical ratings (100V, 1A), mechanical interface specifications (4-position, 1.00mm pitch, through-hole vertical mounting), and operational characteristics (ZIF, slide lock, 20 mating cycles).

For applications subject to RoHS regulatory requirements or environmental compliance mandates, the SLW4S-1C7LF is the appropriate selection. Both parts carry identical REACH unaffected status and UL94 V-0 flammability certification. The operating temperature range of the SLW4S-1C7LF (-55°C ~ 85°C) is narrower than the original part (-55°C ~ 105°C); applications requiring operation above 85°C must retain the SLW4S-1C7.

Frequently Asked Questions (FAQ)

Q: Can SLW4S-1C7LF be used as a direct replacement for SLW4S-1C7 in existing designs?

A: Yes, for applications not requiring operation above 85°C. The SLW4S-1C7LF maintains identical mechanical and electrical specifications across all critical parameters: 4-position configuration, 1.00mm pitch, 100V/1A ratings, through-hole vertical mounting, ZIF operation, and slide lock mechanism. PCB footprints and mating interfaces are identical.

Q: What is the difference between these two parts?

A: The primary differences are RoHS compliance status (SLW4S-1C7LF is compliant; SLW4S-1C7 is non-compliant) and maximum operating temperature (SLW4S-1C7LF: -55°C ~ 85°C; SLW4S-1C7: -55°C ~ 105°C). All other electrical, mechanical, and functional parameters are equivalent.

Q: Are there packaging differences between SLW4S-1C7 and SLW4S-1C7LF?

A: The SLW4S-1C7LF is supplied in Tray packaging, while packaging information for the SLW4S-1C7 is not specified. This distinction affects handling and storage procedures but does not impact component functionality or performance.

Q: Which part should be selected for new designs?

A: For new designs, the SLW4S-1C7LF is the appropriate selection due to RoHS compliance status and improved inventory availability (16,327 units in stock versus 1,030 units for the original part). Confirm that the maximum operating temperature of 85°C meets application requirements.

Q: Are both parts certified to the same standards?

A: Both parts carry identical certifications: UL94 V-0 flammability rating, REACH unaffected status, and MSL 1 (unlimited moisture sensitivity level). RoHS compliance differs as noted above.
