IL-FPR-50S-HF-N1 Equivalent & Substitute Parts

Part Overview

The IL-FPR-50S-HF-N1 is a 50-position FPC (Flat Flexible Connector) manufactured by JAE Electronics, designed for surface mount, right-angle applications with bottom contacts at 0.5mm pitch. This connector features zero insertion force (ZIF) operation, slide lock retention, and gold-plated copper alloy contacts rated for 0.5A per contact at 50V.

The IL-FPR-50S-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.

Key Parameters

Substitute Part Grouping Explanation

The 62684-501100ALF (Amphenol ICC) qualifies as a functional equivalent based on the following critical parameters:

• 50-position configuration with 0.5mm pitch matching the original specification
• Surface mount, right-angle mounting orientation identical to the main part
• Bottom contact configuration maintaining PCB layout compatibility
• Identical voltage (50V) and current (0.5A per contact) ratings
• Solder termination method consistent with the original design
• Zero insertion force (ZIF) operation with slide lock retention
• UL94 V-0 flammability rating meeting the same safety standard
• Operating temperature range (-55°C ~ 85°C) encompassing the original range (-40°C ~ 85°C)

Minor variations in housing material (Polyamide PA9T vs. Polyphenylene Sulfide PPS), actuator material, and physical dimensions (height above board: 2.00mm vs. 1.90mm; FFC thickness: 0.33mm vs. 0.30mm) do not preclude substitution when PCB layout and mechanical clearance accommodate these tolerances.

Parameter Comparison

Engineering Selection Recommendations

The 62684-501100ALF is the primary substitute for the IL-FPR-50S-HF-N1 based on the following factors:

Product Status & Availability: The IL-FPR-50S-HF-N1 is obsolete with limited remaining inventory (894 units). The 62684-501100ALF is active with substantial stock availability (36,200 units), ensuring long-term supply chain continuity.

Electrical Compatibility: Both connectors meet identical voltage (50V) and current (0.5A per contact) specifications. Operating temperature ranges are compatible, with the substitute providing extended low-temperature performance (-55°C vs. -40°C).

Mechanical Compatibility: Pitch, position count, mounting orientation, and contact configuration are identical. The substitute's height above board (2.00mm vs. 1.90mm) and FFC thickness (0.33mm vs. 0.30mm) represent minor variations that require PCB layout verification to confirm mechanical clearance.

Regulatory Compliance: Both connectors carry UL94 V-0 flammability ratings and MSL 1 moisture sensitivity levels. The substitute is RoHS Compliant, providing additional environmental compliance assurance.

Functional Features: Zero insertion force operation and slide lock retention are preserved in the substitute, maintaining assembly process compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 62684-501100ALF be used as a direct replacement for the IL-FPR-50S-HF-N1?

A: Yes, the 62684-501100ALF is functionally equivalent for applications requiring 50-position, 0.5mm pitch FPC connectors with surface mount, right-angle configuration and bottom contacts. Electrical ratings, operating temperature range, and safety certifications are compatible. PCB layout verification is required to confirm mechanical clearance due to minor dimensional differences (height above board and FFC thickness).

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

A: The primary differences are housing material (PPS vs. PA9T), contact material (Copper Alloy vs. Phosphor Bronze), physical dimensions (height and thickness), and product status (obsolete vs. active). These differences do not affect electrical performance or functional compatibility when mechanical clearance is confirmed.

Q: Is the substitute connector available in the same packaging as the original?

A: The IL-FPR-50S-HF-N1 packaging is not specified in the original documentation. The 62684-501100ALF is supplied in Tape & Reel (TR) packaging, which is standard for high-volume surface mount applications.

Q: What is the operating temperature range difference, and does it matter?

A: The IL-FPR-50S-HF-N1 operates from -40°C to 85°C, while the 62684-501100ALF operates from -55°C to 85°C. The substitute provides extended low-temperature capability. If your application operates within the original -40°C to 85°C range, both connectors are suitable.

Q: Are there any compliance or certification differences?

A: Both connectors meet UL94 V-0 flammability standards and MSL 1 moisture sensitivity levels. The substitute is RoHS Compliant, providing additional environmental compliance. The original part's RoHS status is not specified.

Q: How do I verify mechanical compatibility on my PCB?

A: Compare the height above board (1.90mm vs. 2.00mm) and FFC thickness (0.30mm vs. 0.33mm) against your PCB design clearances, component placement, and cable routing. These minor dimensional variations may require layout adjustments in space-constrained applications.
