IL-FPR-U20S-HF-N1 Equivalent & Substitute Parts

Part Overview

The IL-FPR-U20S-HF-N1 is a 20-position FPC (Flat Flexible Connector) manufactured by JAE Electronics, designed for surface mount, right-angle applications with 0.50mm pitch contacts. 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 product is currently obsolete, making identification of equivalent substitute parts essential for ongoing system support, maintenance, and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the IL-FPR-U20S-HF-N1 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 20
• Pitch: 0.020" (0.50mm)
• Mounting Type: Surface Mount, Right Angle
• Connector/Contact Type: Contacts, Top
• Termination: Solder
• Locking Feature: Slide Lock
• Features: Zero Insertion Force (ZIF)
• Flat Flex Type: FPC

Allowable Variations:

• Voltage Rating: Substitute must meet or exceed 50V
• Current Rating: Substitute must meet or exceed 0.5A per contact
• Operating Temperature: Substitute must cover or exceed -40°C ~ 85°C range
• Contact Material: Copper Alloy or Phosphor Bronze acceptable
• Contact Finish: Gold acceptable
• Housing Material: PPS Glass Filled or Thermoplastic acceptable
• Height Above Board: Minor variations acceptable within mechanical constraints

The substitute part 2-1734839-0 (TE Connectivity AMP Connectors) meets all mandatory matching parameters and exceeds performance specifications in voltage rating and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The 2-1734839-0 (TE Connectivity AMP Connectors) is a direct functional substitute for the obsolete IL-FPR-U20S-HF-N1. Both connectors share identical mechanical and electrical interface specifications for the 20-position, 0.50mm pitch FPC application.

Compliance and Certification:

• Both parts carry UL94 V-0 flammability rating
• Both parts have MSL 1 (Unlimited) moisture sensitivity classification
• Both parts are classified as EAR99 for export control purposes
• The substitute part is RoHS Compliant and carries active product status

Performance Advantages of Substitute:

• Voltage rating of 250V exceeds the original 50V specification
• Solder retention feature provides additional mechanical robustness
• Active product status ensures ongoing availability and supply chain continuity

Mechanical Compatibility: The height above board difference of 0.006" (0.15mm) between the original and substitute is within typical PCB design tolerances and does not preclude direct substitution in standard applications.

Frequently Asked Questions (FAQ)

Q: Can the 2-1734839-0 be used as a direct replacement for the IL-FPR-U20S-HF-N1?

A: Yes. Both connectors share identical position count (20), pitch (0.50mm), mounting configuration (surface mount right angle), contact type (top contacts), termination method (solder), and locking mechanism (slide lock with ZIF). The substitute meets or exceeds all electrical and thermal specifications of the original part.

Q: What is the significance of the height above board difference?

A: The IL-FPR-U20S-HF-N1 has a height of 0.075" (1.90mm), while the 2-1734839-0 measures 0.081" (2.05mm). This 0.006" (0.15mm) difference is within standard PCB design clearance tolerances and does not affect mechanical compatibility or electrical performance in typical applications.

Q: Does the substitute part have better electrical ratings?

A: The 2-1734839-0 has a voltage rating of 250V compared to the original 50V specification. Both parts maintain identical current rating of 0.5A per contact. The higher voltage rating of the substitute provides additional design margin and does not introduce incompatibility.

Q: What is the packaging difference between these parts?

A: The IL-FPR-U20S-HF-N1 packaging information is not specified in the original documentation. The 2-1734839-0 is supplied in Cut Tape (CT) packaging format.

Q: Are there temperature range considerations for substitution?

A: The original part operates from -40°C to 85°C, while the substitute operates from -20°C to 85°C. The substitute does not extend the lower temperature limit. Applications requiring operation below -20°C must evaluate this specification difference against system requirements.

Q: What is the significance of the "Solder Retention" feature on the substitute?

A: The 2-1734839-0 includes solder retention as an additional feature beyond the ZIF mechanism present on both parts. This feature provides enhanced mechanical stability during solder reflow processes and does not affect compatibility with the original connector interface.

Q: Is the substitute part RoHS compliant?

A: Yes. The 2-1734839-0 is RoHS Compliant. The original part's RoHS status is not specified in the provided documentation.
