SLW19S-1C7LF Equivalent & Substitute Parts

Part Overview

The SLW19S-1C7LF is a 19-position FFC/FPC vertical connector manufactured by Amphenol ICC (FCI) with 1.00mm pitch and through-hole mounting. This connector features a slide lock mechanism and zero insertion force (ZIF) design, rated for 100V and 1A operation across -55°C to 85°C. The product is currently obsolete, necessitating identification of active equivalent alternatives to maintain design continuity and ensure supply chain availability.

Key Parameters

Substitute Part Grouping Explanation

The HLW19S-2C7LF qualifies as a direct substitute based on the following critical parameters that determine functional compatibility:

• Position Count: Both parts feature 19 positions
• Pitch: Both maintain 0.039" (1.00mm) spacing
• Mounting Configuration: Both are through-hole mounted, vertical orientation, 1-sided contacts
• Electrical Ratings: Both rated 100V and 1A
• Operating Temperature Range: Both operate -55°C to 85°C
• Termination Style: Both use kinked pin termination
• FFC/FPC Thickness: Both accommodate 0.33mm flat flex cable
• Contact Material & Finish: Both use phosphor bronze with tin finish
• Compliance: Both are RoHS compliant and carry UL94 V-0 flammability rating

The HLW19S-2C7LF represents an active product with improved supply availability and enhanced mechanical durability through increased mating cycles.

Parameter Comparison

Engineering Selection Recommendations

The HLW19S-2C7LF is the appropriate substitute for the obsolete SLW19S-1C7LF. Both connectors maintain identical electrical and mechanical specifications across all critical parameters required for PCB integration and signal integrity. The substitute offers the following advantages:

• Active product status ensures ongoing availability and manufacturing support
• Increased mating cycle rating (30 vs. 20) provides extended operational life
• PBT housing material offers enhanced chemical and thermal stability compared to polyamide
• RoHS compliance and UL94 V-0 certification maintained across both products
• Identical pitch, position count, and mounting configuration enable direct PCB layout compatibility

The housing material change from polyamide to PBT does not affect electrical performance or mechanical fit, as both materials are glass-filled and meet the same flammability standards.

Frequently Asked Questions (FAQ)

Q: Can HLW19S-2C7LF be used as a direct replacement on existing PCBs designed for SLW19S-1C7LF?

A: Yes. Both connectors share identical pitch (1.00mm), position count (19), mounting type (through-hole), and footprint dimensions. PCB layouts require no modification.

Q: What is the difference in housing material, and does it affect performance?

A: The SLW19S-1C7LF uses polyamide (PA) nylon, while the HLW19S-2C7LF uses polybutylene terephthalate (PBT). Both are glass-filled and rated UL94 V-0. PBT offers improved chemical resistance and thermal stability. Electrical and mechanical performance remain equivalent.

Q: Are there differences in mating cycle ratings?

A: The SLW19S-1C7LF is rated for 20 mating cycles, while the HLW19S-2C7LF is rated for 30 mating cycles. This indicates the substitute connector has extended mechanical durability for applications requiring more frequent connection/disconnection cycles.

Q: Do both connectors support the same voltage and current ratings?

A: Yes. Both are rated 100V and 1A with identical operating temperature ranges of -55°C to 85°C.

Q: Is the substitute part RoHS compliant?

A: Yes. The HLW19S-2C7LF is RoHS compliant, matching the compliance status of the original part.

Q: What is the height difference above the PCB?

A: The SLW19S-1C7LF has a height of 0.217" (5.50mm), while the HLW19S-2C7LF has a height of 0.232" (5.90mm). This 0.015" (0.40mm) difference should be evaluated for applications with height constraints.
