SLW24S-1C7LF Equivalent & Substitute Parts

Part Overview

The SLW24S-1C7LF is a 24-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, making identification of compatible substitute parts essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The HLW24S-2C7LF qualifies as a substitute for the SLW24S-1C7LF based on the following critical parameters that determine functional compatibility:

• Position Count: Both parts feature 24 positions
• Pitch: Both maintain 0.039" (1.00mm) spacing
• Mounting Configuration: Both use through-hole mounting with vertical, 1-sided contact orientation
• Electrical Ratings: Both support 100V voltage and 1A current
• Operating Temperature Range: Both operate across -55°C to 85°C
• Contact Material & Finish: Both use phosphor bronze contacts with tin finish
• Termination Style: Both employ kinked pin termination
• FFC/FPC Thickness: Both accommodate 0.33mm flat flex cable thickness
• Compliance: Both are RoHS compliant with UL94 V-0 flammability rating

The substitute part represents an active product with improved availability and updated material composition (PBT housing vs. PA housing in the original).

Parameter Comparison

Engineering Selection Recommendations

The HLW24S-2C7LF is the manufacturer-recommended substitute for the obsolete SLW24S-1C7LF. Both parts maintain identical electrical specifications (100V, 1A) and operating temperature range (-55°C to 85°C), with full RoHS compliance and UL94 V-0 flammability certification.

Key considerations for selection:

• Product Availability: The substitute is an active product with significantly higher inventory (5876 pcs vs. 748 pcs), ensuring long-term procurement viability
• Housing Material: The substitute uses PBT (polybutylene terephthalate) instead of PA (polyamide), providing enhanced chemical and thermal resistance
• Mechanical Durability: The substitute supports 30 mating cycles compared to 20 cycles in the original, indicating improved mechanical longevity
• Physical Dimensions: The substitute has a slightly increased height above board (5.90mm vs. 5.50mm), requiring verification of available PCB clearance
• Locking Mechanism: The original includes a slide lock feature; the substitute does not. Applications requiring positive cable retention must account for this difference

Both parts are REACH-affected and classified under ECCN EAR99 with identical HTSUS code 8536.69.4051.

Frequently Asked Questions (FAQ)

Q: Can HLW24S-2C7LF directly replace SLW24S-1C7LF in existing designs?

A: Yes, for applications where the slide lock feature is not critical. Both connectors share identical position count (24), pitch (1.00mm), electrical ratings (100V, 1A), and operating temperature range (-55°C to 85°C). The primary design consideration is the 0.4mm increase in height above board (5.90mm vs. 5.50mm), which must be verified against available PCB clearance.

Q: What is the significance of the housing material change from PA to PBT?

A: PBT (polybutylene terephthalate) offers superior chemical resistance and thermal stability compared to PA (polyamide). This material upgrade enhances connector reliability in demanding environments and contributes to the increased mating cycle rating (30 vs. 20 cycles).

Q: Does the absence of a slide lock on the HLW24S-2C7LF affect compatibility?

A: The slide lock feature on the original SLW24S-1C7LF provides positive cable retention during mating. The HLW24S-2C7LF lacks this feature. Applications requiring positive locking must implement alternative cable retention methods or confirm that the connector's friction fit is sufficient for the intended use case.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both SLW24S-1C7LF and HLW24S-2C7LF are RoHS compliant, carry UL94 V-0 flammability certification, and are REACH-affected components. Both are classified under ECCN EAR99.

Q: What is the packaging difference between these parts?

A: The original SLW24S-1C7LF packaging is not specified. The substitute HLW24S-2C7LF is supplied in tray packaging, which is standard for high-volume procurement and automated assembly processes.

Q: Why is the mating cycle rating different?

A: The HLW24S-2C7LF is rated for 30 mating cycles compared to 20 cycles for the SLW24S-1C7LF. This reflects the improved mechanical durability of the updated design and PBT housing material, providing extended connector lifespan in applications with frequent mating/unmating cycles.
