SLW7S-1C7ALF FPC Connector Equivalent & Substitute Parts

Part Overview

The SLW7S-1C7ALF is a 7-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 kinked pin termination for through-hole PCB mounting. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for FPC connectors is determined by strict alignment of electrical and mechanical parameters. The primary criteria are:

• Number of positions (7 positions required)
• Pitch specification (1.00mm required)
• Connector orientation (vertical, single-sided contacts required)
• Mounting method (through-hole PCB mounting required)
• Termination style (kinked pin required)
• Voltage and current ratings (must meet or exceed application requirements)
• Operating temperature range (must encompass application environment)
• Flammability compliance (UL94 V-0 required)

The substitute part 0528060710 (Molex 52806 series) satisfies the core mechanical and electrical compatibility requirements: identical position count, pitch, orientation, mounting type, and termination method. Both parts feature UL94 V-0 flammability rating and RoHS compliance.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0528060710 connector provides functional equivalence for applications where the electrical and thermal requirements do not exceed its specified ratings. The substitute part is currently in active production status, ensuring long-term availability compared to the obsolete SLW7S-1C7ALF.

Design considerations for substitution:

The substitute part operates at reduced voltage (50V vs. 100V) and current (0.5A vs. 1A) ratings. Applications requiring the full 100V or 1A specifications of the original part cannot use this substitute without design modification.

The operating temperature range of the substitute (−20°C to 80°C) is narrower than the original (−55°C to 85°C). Applications requiring operation below −20°C or above 80°C are not compatible with this substitute.

The substitute part supports 10 mating cycles versus 20 for the original. Applications with high connector cycling requirements should account for this reduced durability specification.

Both parts maintain UL94 V-0 flammability compliance and RoHS compliance status, supporting equivalent safety and environmental regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0528060710 be used as a direct replacement for the SLW7S-1C7ALF?

A: Direct substitution is possible only when application requirements do not exceed the electrical and thermal specifications of the Molex part. The substitute operates at 50V maximum (vs. 100V) and 0.5A maximum (vs. 1A), with an operating temperature range of −20°C to 80°C (vs. −55°C to 85°C). Verify that your application requirements fall within these limits.

Q: What are the mechanical compatibility factors between these connectors?

A: Both connectors share identical mechanical specifications: 7 positions, 1.00mm pitch, vertical single-sided contact orientation, through-hole PCB mounting, and kinked pin termination. Physical height above board differs slightly (5.50mm vs. 5.40mm), which is negligible for most PCB layouts. FFC thickness differs by 0.03mm (0.33mm vs. 0.30mm), which may affect cable routing in space-constrained designs.

Q: Are there compliance or certification differences between these parts?

A: Both parts carry UL94 V-0 flammability ratings and RoHS compliance. The substitute is ROHS3 compliant, representing a more recent compliance standard. Both parts have MSL rating 1 (unlimited moisture sensitivity), indicating no special storage or handling requirements.

Q: What is the significance of the mating cycle difference?

A: The original part supports 20 mating cycles while the substitute supports 10. This specification indicates the number of times the connector can be mated and unmated before performance degradation. Applications involving frequent connector cycling should consider this reduced durability specification.

Q: How do the contact finish specifications differ?

A: The original part features gold-plated contacts (phosphor bronze base), while the substitute uses tin plating (phosphor bronze base). Both materials provide adequate electrical conductivity and corrosion resistance for standard applications. Gold plating typically offers superior corrosion resistance in harsh environments.
