IL-FPR-U50S-HF-N1 Equivalent & Substitute Parts

Part Overview

The IL-FPR-U50S-HF-N1 is a 50-position FPC (Flat Flexible Connector) manufactured by JAE Electronics. This surface mount, right-angle connector features a 0.5mm pitch and is designed for applications requiring Zero Insertion Force (ZIF) operation with solder termination. The product is currently obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, maintenance, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IL-FPR-U50S-HF-N1 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 50
• Pitch: 0.020" (0.50mm)
• Connector Type: FPC Contacts, Top
• Mounting Type: Surface Mount, Right Angle
• Termination: Solder
• FFC/FCB Thickness: 0.30mm
• Locking Feature: Slide Lock
• Cable End Type: Tapered
• Features: Zero Insertion Force (ZIF)
• Voltage Rating: 50V
• Current Rating: 0.5A per Contact
• Material Flammability: UL94 V-0
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part 62684-502100ALF (Amphenol ICC) meets all mandatory matching parameters. Minor variations in housing material (Polyamide PA9T vs. Polyphenylene Sulfide PPS), actuator material, contact material (Phosphor Bronze vs. Copper Alloy), and height above board (0.079" vs. 0.075") do not affect functional equivalence within the specified electrical and mechanical constraints.

Parameter Comparison

Engineering Selection Recommendations

The 62684-502100ALF from Amphenol ICC is a direct functional equivalent for the obsolete IL-FPR-U50S-HF-N1. Selection of this substitute is supported by:

Product Status: The substitute part maintains active production status, ensuring long-term availability and supply chain continuity compared to the obsolete original.

Electrical Equivalence: Both connectors share identical voltage (50V) and current (0.5A per contact) ratings, supporting equivalent circuit performance.

Mechanical Compatibility: Pitch (0.50mm), position count (50), mounting configuration (surface mount, right angle), and termination method (solder) are identical. The height variance of 0.004" (0.10mm) is within typical PCB layout tolerances for right-angle connectors.

Environmental & Compliance: Both parts meet UL94 V-0 flammability requirements and MSL 1 moisture sensitivity specifications. The substitute offers extended operating temperature range (-55°C to 85°C vs. -40°C to 85°C) and RoHS compliance certification.

Packaging: The substitute is available in Tape & Reel format, supporting automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 62684-502100ALF directly replace the IL-FPR-U50S-HF-N1 on existing PCBs?

A: Yes. Both connectors share identical pitch (0.50mm), position count (50), mounting type (surface mount, right angle), and solder termination. The 0.004" height difference does not affect PCB footprint compatibility.

Q: What are the key differences between these two connectors?

A: The primary differences are housing material (Polyamide PA9T vs. Polyphenylene Sulfide PPS), contact material (Phosphor Bronze vs. Copper Alloy), and operating temperature range (-55°C to 85°C vs. -40°C to 85°C). These variations do not affect functional equivalence within the specified electrical parameters.

Q: Is the substitute part RoHS compliant?

A: Yes. The 62684-502100ALF is RoHS compliant. Compliance status for the original IL-FPR-U50S-HF-N1 was not specified in available documentation.

Q: What is the availability difference between these parts?

A: The IL-FPR-U50S-HF-N1 is obsolete with limited remaining inventory. The 62684-502100ALF is in active production with significantly higher stock levels, ensuring reliable supply for new designs and ongoing support.

Q: Are there any thermal performance differences?

A: The substitute supports a lower operating temperature limit (-55°C vs. -40°C), providing broader thermal range coverage. Both parts support the same upper temperature limit (85°C).

Q: Does packaging format affect compatibility?

A: No. The substitute's Tape & Reel packaging is a manufacturing/assembly consideration and does not affect electrical or mechanical compatibility with the original part's footprint and function.
