IL-FPR-U10S-HF-N1 Equivalent & Substitute Parts

Part Overview

The IL-FPR-U10S-HF-N1 is a 10-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, slide lock retention, and gold-plated copper alloy contacts rated for 0.5A per contact at 50V.

The IL-FPR-U10S-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

Substitution of the IL-FPR-U10S-HF-N1 is determined by strict equivalence across the following critical parameters:

• Connector Type & Pitch: Both main and substitute parts must be FPC connectors with 0.5mm (0.020") pitch to ensure mechanical and electrical compatibility with existing FFC ribbon cables.
• Position Count: 10-position configuration is mandatory for signal routing compatibility.
• Mounting Configuration: Surface mount, right-angle orientation must be maintained for PCB layout compatibility.
• Contact Configuration: Top-mounted contacts are required for the specified application.
• Termination & Locking: Solder termination with slide lock retention ensures assembly process compatibility and mechanical stability.
• Electrical Ratings: Voltage and current ratings must meet or exceed the original specification (50V, 0.5A per contact).
• Environmental Compliance: UL94 V-0 flammability rating and MSL 1 classification ensure regulatory and reliability equivalence.

The TE Connectivity AMP Connectors part 1-1734839-0 meets these substitution criteria across all critical parameters.

Parameter Comparison

Engineering Selection Recommendations

The TE Connectivity AMP Connectors part 1-1734839-0 is a direct functional substitute for the IL-FPR-U10S-HF-N1. Both connectors share identical mechanical and electrical core specifications: 10-position, 0.5mm pitch, surface mount right-angle configuration with solder termination and slide lock retention.

The substitute part offers the following advantages:

• Active Product Status: The 1-1734839-0 is currently in active production with 34,394 units in stock, ensuring long-term supply availability compared to the obsolete IL-FPR-U10S-HF-N1.
• Enhanced Voltage Rating: The substitute provides 250V rating versus the original 50V, offering greater electrical margin for applications within the original voltage envelope.
• Regulatory Compliance: Both parts maintain UL94 V-0 flammability certification and MSL 1 moisture sensitivity classification, ensuring equivalent environmental performance.
• RoHS3 Compliance: The substitute is explicitly RoHS3 compliant, supporting regulatory requirements for new designs and production.

Design considerations for substitution:

• Operating Temperature: The substitute operates from -20°C to 85°C, compared to the original -40°C to 85°C. Applications requiring operation below -20°C require thermal analysis.
• Height Variation: The substitute is 0.081" (2.05mm) above board versus 0.075" (1.90mm) for the original. PCB layout clearance must be verified for applications with height constraints.
• Packaging: The substitute is supplied in Tape & Reel format, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the 1-1734839-0 be used as a direct replacement for the IL-FPR-U10S-HF-N1 in existing designs?

A: Yes. Both connectors share identical pitch (0.5mm), position count (10), mounting configuration (surface mount right-angle), contact arrangement (top), and termination method (solder). Mechanical and electrical compatibility is established across all critical parameters. Design verification is required only for applications operating below -20°C or with height constraints below 2.05mm.

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

A: The primary differences are: (1) voltage rating (250V substitute vs. 50V original), (2) operating temperature lower limit (-20°C substitute vs. -40°C original), (3) height above board (2.05mm substitute vs. 1.90mm original), and (4) product status (active vs. obsolete). All other electrical and mechanical parameters are equivalent.

Q: Are there any compatibility issues with existing FFC ribbon cables?

A: No. Both connectors use identical 0.5mm pitch, tapered cable end type, and top contact configuration. Existing FFC ribbons designed for the IL-FPR-U10S-HF-N1 are mechanically and electrically compatible with the 1-1734839-0 substitute.

Q: What is the significance of the height difference (0.075" vs. 0.081")?

A: The 0.006" (0.15mm) height increase of the substitute connector may affect PCB layout in applications with tight vertical clearance constraints. PCB design review is necessary to confirm adequate clearance above the connector for cable routing and component placement.

Q: Does the substitute part meet the same regulatory requirements?

A: Yes. Both connectors carry UL94 V-0 flammability certification and MSL 1 moisture sensitivity classification. The substitute additionally provides RoHS3 compliance documentation, supporting regulatory requirements for new production and design updates.

Q: What packaging format is the substitute supplied in?

A: The 1-1734839-0 is supplied in Tape & Reel (TR) format, optimized for automated pick-and-place assembly. The original IL-FPR-U10S-HF-N1 packaging format is not specified in available documentation.
