SLW4S-1C7BLF Equivalent & Substitute Parts

Part Overview

The SLW4S-1C7BLF is a 4-position FPC (Flat Flexible) connector manufactured by Amphenol ICC (FCI) with vertical, single-sided contacts and 1.00mm pitch. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing production and maintenance applications. The connector features a slide lock mechanism, zero insertion force (ZIF) design, and through-hole mounting configuration suitable for flexible cable termination in compact electronic assemblies.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SLW4S-1C7BLF is determined by the following critical parameters:

• Connector Position Count: Must be 4 positions
• Pitch Specification: Must be 0.039" (1.00mm)
• Mounting Configuration: Must be through-hole
• Contact Orientation: Must be vertical, single-sided
• Flat Flex Type: Must be FPC
• Termination Style: Must be kinked pin

The substitute part 0528060410 (Molex 52806 series) satisfies all core mechanical and electrical compatibility requirements. However, differences exist in secondary parameters including voltage rating, current capacity, operating temperature range, locking mechanism, and contact finish material. These differences must be evaluated against specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The Molex 0528060410 connector provides mechanical and electrical compatibility with the obsolete SLW4S-1C7BLF for applications operating within reduced electrical and thermal specifications. Both connectors maintain UL94 V-0 flammability compliance and unlimited moisture sensitivity level (MSL 1) ratings, supporting deployment in standard industrial and consumer electronics environments.

Selection of the Molex substitute requires verification that application requirements do not exceed the following reduced parameters:

• Voltage operation limited to 50V maximum (versus 100V for the original)
• Current per contact limited to 0.5A maximum (versus 1A for the original)
• Operating temperature range constrained to -20°C ~ 80°C (versus -55°C ~ 85°C for the original)
• Mating cycle life reduced to 10 cycles (versus 20 cycles for the original)

The Molex part offers the advantage of active product status with established supply chain availability (19,473 units in stock versus 1,170 units for the obsolete Amphenol part). Both components carry equivalent ECCN (EAR99) and HTSUS (8536.69.4051) classifications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0528060410 be used as a direct replacement for the SLW4S-1C7BLF?

A: Mechanical and pin compatibility is confirmed. Electrical compatibility depends on application requirements. If your design operates at voltages above 50V, currents above 0.5A per contact, or temperatures below -20°C or above 80°C, the Molex substitute is not suitable.

Q: What are the key differences between these connectors?

A: The primary differences are voltage rating (100V vs. 50V), current rating (1A vs. 0.5A), operating temperature range (-55°C ~ 85°C vs. -20°C ~ 80°C), mating cycles (20 vs. 10), contact finish (gold vs. tin), and housing material (PA nylon vs. PPS). Both maintain identical pitch, position count, and mounting configuration.

Q: Why does the Molex part have a lower voltage and current rating?

A: These are design specifications set by the manufacturer based on the connector's internal geometry, contact cross-section, and material properties. The Molex 52806 series is engineered for different application requirements than the Amphenol SLW-S series.

Q: Are there any compliance concerns with substitution?

A: Both connectors are RoHS compliant (RoHS vs. ROHS3) and carry identical ECCN and HTSUS classifications. The Molex part is REACH Unaffected while the Amphenol part is REACH Affected. Verify REACH compliance requirements for your specific application and supply chain.

Q: What is the difference between the contact finishes?

A: The SLW4S-1C7BLF uses gold plating on phosphor bronze contacts, while the 0528060410 uses tin plating. Gold provides superior corrosion resistance and lower contact resistance; tin offers cost efficiency for standard industrial applications.

Q: Can I use the Molex connector in high-temperature applications?

A: The Molex 0528060410 is rated to 80°C maximum. If your application requires operation above 80°C or below -20°C, this substitute is not appropriate. The original SLW4S-1C7BLF supports -55°C ~ 85°C operation.
