SLW20S-1C7BLF FPC Connector Equivalent & Substitute Parts

Part Overview

The SLW20S-1C7BLF is a 20-position FPC (Flat Flexible) connector manufactured by Amphenol ICC (FCI) with vertical, single-sided contacts and 1.00mm pitch. This connector features a slide lock mechanism, zero insertion force (ZIF) operation, and through-hole mounting. 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

Substitution eligibility for the SLW20S-1C7BLF is determined by the following critical parameters:

• Connector Type & Position Count: Must be FPC with 20 positions
• Pitch: Must be 0.039" (1.00mm)
• Contact Configuration: Must be vertical, single-sided
• Mounting Type: Must be through-hole
• Termination: Must be kinked pin
• Contact Material: Must be phosphor bronze
• Flammability Rating: Must meet UL94 V-0

The Molex 0528062010 meets these core substitution criteria. However, differences exist in secondary parameters including voltage rating, current rating, operating temperature range, contact finish, housing material, and mating cycle specifications. These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0528062010 is an active product with current manufacturing support and ROHS3 compliance, providing supply chain continuity for the obsolete SLW20S-1C7BLF. Both connectors share identical core mechanical and electrical specifications for position count, pitch, contact configuration, and mounting type.

Application suitability depends on specific operational requirements:

• Voltage & Current Derating: The Molex substitute has lower voltage (50V vs. 100V) and current (0.5A vs. 1A) ratings. Applications operating at or near the original specifications require verification that the substitute ratings remain adequate.

• Temperature Range: The Molex part operates within -20°C ~ 80°C versus the original -55°C ~ 85°C. Applications requiring extended low-temperature operation below -20°C or high-temperature operation above 80°C are not suitable for this substitute.

• Contact Finish & Material Compatibility: The original uses gold-plated contacts; the substitute uses tin plating. Contact finish selection affects corrosion resistance and mating force characteristics. Verify compatibility with mating connector specifications.

• Housing Material: The original uses glass-filled polyamide; the substitute uses polyphenylene sulfide (PPS). Both materials meet UL94 V-0 flammability requirements. PPS offers superior chemical and thermal stability.

• Mating Cycle Life: The original supports 20 cycles; the substitute supports 10 cycles. Applications requiring frequent connector mating should account for this reduced cycle rating.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0528062010 directly replace the SLW20S-1C7BLF in all applications?

A: Direct replacement is possible only when application requirements fall within the Molex part's electrical and thermal specifications. Verify that operating voltage, current, and temperature ranges do not exceed the substitute's ratings.

Q: What is the significance of the different contact finishes (gold vs. tin)?

A: Contact finish affects mating force, wear resistance, and corrosion performance. Gold provides superior corrosion resistance and lower contact resistance. Tin plating is more economical but may require verification of compatibility with the mating connector's contact material and plating.

Q: Are both connectors mechanically compatible with the same PCB footprint?

A: Both connectors have identical pitch (1.00mm), position count (20), and through-hole mounting configuration. PCB footprint compatibility is confirmed. However, verify height above board specifications (5.50mm vs. 5.40mm) for clearance in confined spaces.

Q: What compliance certifications apply to each part?

A: The SLW20S-1C7BLF is RoHS Compliant. The Molex 0528062010 is ROHS3 Compliant and REACH Unaffected. Both meet UL94 V-0 flammability requirements.

Q: How do the mating cycle ratings affect component selection?

A: Mating cycle ratings indicate the number of times a connector can be mated and unmated while maintaining electrical and mechanical performance. The original supports 20 cycles; the substitute supports 10 cycles. Applications with infrequent mating are unaffected. Applications requiring frequent connector cycling should evaluate whether the reduced cycle rating is acceptable.

Q: What inventory considerations apply to these parts?

A: The SLW20S-1C7BLF is obsolete with limited remaining stock (1073 pcs). The Molex 0528062010 is an active product with robust inventory availability (21712 pcs), ensuring long-term procurement viability.
