IL-FPR-U40S-HF-N1 Equivalent & Substitute Parts

Part Overview

The IL-FPR-U40S-HF-N1 is a 40-position FPC (Flat Flexible Connector) manufactured by JAE Electronics, designed for surface mount, right-angle applications with 0.5mm pitch contacts. This connector features zero insertion force (ZIF) operation, gold-plated copper alloy contacts, and is rated for 50V and 0.5A per contact across an operating temperature range of -40°C to 85°C.

The IL-FPR-U40S-HF-N1 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this connector.

Substitute Part Grouping Explanation

Substitution eligibility for the IL-FPR-U40S-HF-N1 is determined by strict alignment of the following critical parameters:

Connector Configuration: 40 positions, 0.5mm pitch, top-contact FPC type
Mounting Specification: Surface mount, right-angle orientation
Electrical Performance: 50V voltage rating, 0.5A per contact current capacity
Termination Method: Solder termination
Mechanical Compatibility: FFC/FCB thickness tolerance, slide lock mechanism, ZIF operation
Environmental Compliance: UL94 V-0 flammability rating, operating temperature range

The substitute part 62684-402100ALF (Amphenol ICC/FCI) meets all critical substitution criteria. This part maintains identical position count, pitch, mounting type, contact configuration, electrical ratings, and locking mechanism. Both parts support the same termination method and flammability standard.

Engineering Selection Recommendations

The 62684-402100ALF qualifies as a direct substitute for the IL-FPR-U40S-HF-N1 based on the following engineering criteria:

Electrical Equivalence: Both connectors maintain identical voltage (50V) and current (0.5A per contact) ratings, ensuring no degradation in electrical performance.

Mechanical Compatibility: The 40-position, 0.5mm pitch configuration is identical. The height variance (1.90mm vs. 2.00mm) represents a 0.10mm difference, which is within typical PCB layout tolerances for right-angle surface mount applications. Both employ slide lock mechanisms and support ZIF operation.

Environmental Compliance: Both parts carry UL94 V-0 flammability certification. The substitute part supports an extended operating temperature range (-55°C to 85°C versus -40°C to 85°C), providing additional thermal margin.

Supply Chain Status: The substitute part is in active production with 3,448 units in stock, compared to the obsolete status of the original part. This ensures long-term availability and supply continuity.

Regulatory Compliance: The 62684-402100ALF is RoHS compliant and REACH unaffected, meeting current regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the 62684-402100ALF be used as a direct replacement in existing designs?

A: Yes. The substitute part maintains identical electrical ratings (50V, 0.5A per contact), connector configuration (40 positions, 0.5mm pitch), mounting type (surface mount, right angle), and locking mechanism (slide lock with ZIF). The 0.10mm height difference is within standard PCB layout tolerances.

Q: What is the significance of the contact material difference (Copper Alloy vs. Phosphor Bronze)?

A: Both materials are suitable for the specified 0.5A per contact current rating and gold plating finish. Phosphor bronze offers enhanced spring properties and durability. This substitution does not compromise electrical or mechanical performance.

Q: Does the extended operating temperature range of the substitute part affect compatibility?

A: No. The substitute part's wider operating range (-55°C to 85°C) is a superset of the original specification (-40°C to 85°C). This provides additional thermal margin without introducing compatibility issues.

Q: Are there packaging differences between the two parts?

A: The original part (IL-FPR-U40S-HF-N1) packaging is not specified. The substitute part (62684-402100ALF) is available in Cut Tape (CT) and Digi-Reel packaging options, supporting standard component procurement workflows.

Q: What is the FFC/FCB thickness tolerance for the substitute part?

A: The 62684-402100ALF is available in both 0.30mm and 0.33mm thicknesses. For direct substitution with the IL-FPR-U40S-HF-N1, specify the 0.30mm thickness variant to maintain exact mechanical compatibility.

Q: Is the substitute part RoHS compliant?

A: Yes. The 62684-402100ALF is RoHS compliant and REACH unaffected, meeting current regulatory requirements for electronic components.
