IL-FPR-21S-HF-N1 FPC Connector Equivalent & Substitute Parts

Part Overview

The IL-FPR-21S-HF-N1 is a 21-position FPC (Flat Flexible) connector manufactured by JAE Electronics, designed for surface mount, right-angle applications with 0.50mm pitch contacts. This connector features bottom-contact configuration, zero insertion force (ZIF) operation, and solder termination for flexible cable assemblies.

The IL-FPR-21S-HF-N1 is classified as obsolete. Equivalent and substitute parts are necessary to maintain design continuity, ensure supply chain availability, and support ongoing production requirements for applications utilizing this connector footprint and electrical interface.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the IL-FPR-21S-HF-N1 is determined by strict alignment of the following critical parameters:

• Connector Configuration: 21 positions, 0.50mm pitch, bottom-contact, surface mount, right-angle orientation
• Electrical Specifications: Minimum 50V voltage rating, minimum 0.5A current rating per contact
• Termination Method: Solder termination required
• Mechanical Interface: Slide lock locking mechanism, ZIF operation
• Environmental Compliance: UL94 V-0 flammability rating, MSL 1 classification
• Physical Constraints: Height above board and FFC/FCB thickness compatibility

The three substitute parts listed below meet these core substitution criteria and are classified as active products with current manufacturing availability.

Parameter Comparison

Engineering Selection Recommendations

0524372171 (Molex Easy-On 52437 Series)

This substitute maintains full electrical and mechanical compatibility with the IL-FPR-21S-HF-N1. The connector is RoHS3 compliant and active in production. Height above board tolerance (0.079" vs. 0.075") and housing material composition (Polyamide PA46 vs. Polyphenylene Sulfide PPS) represent minor mechanical variations within acceptable PCB layout margins. Solder retention feature provides additional manufacturing robustness.

086260021340829+ (KYOCERA AVX 6260 Series)

This substitute meets core electrical and mechanical requirements with active product status. Current rating is specified at 0.4A per contact, which is below the original 0.5A specification. This part is suitable for applications where per-contact current demand does not exceed 0.4A. RoHS3 compliance is confirmed. Material flammability rating is not specified in available documentation.

SFV21R-1STBE1HLF (Amphenol ICC SFV-R Series)

This substitute provides the widest operating temperature range (-55°C ~ 105°C) compared to the original specification (-40°C ~ 85°C). FFC/FCB thickness tolerance (0.33mm vs. 0.30mm) requires verification against cable assembly specifications. RoHS compliance is confirmed. REACH status is listed as affected, requiring compliance verification for end-use applications subject to REACH regulations.

Frequently Asked Questions (FAQ)

Q: Can the 086260021340829+ substitute be used in all applications where the IL-FPR-21S-HF-N1 was specified?

A: The 086260021340829+ is suitable for applications where per-contact current does not exceed 0.4A. If the original design requires 0.5A per contact, the Molex 0524372171 or Amphenol ICC SFV21R-1STBE1HLF are preferred alternatives.

Q: What is the impact of height above board differences between substitute parts?

A: The IL-FPR-21S-HF-N1 specifies 0.075" (1.90mm) height. The Molex and KYOCERA AVX substitutes are 0.079" (2.00mm), and the Amphenol ICC is 0.071" (1.80mm). These variations require PCB layout verification to ensure clearance and mechanical fit within the target assembly.

Q: Are all substitute parts RoHS compliant?

A: The Molex 0524372171 is RoHS3 compliant. The KYOCERA AVX 086260021340829+ is RoHS3 compliant. The Amphenol ICC SFV21R-1STBE1HLF is RoHS compliant. Verify specific RoHS version requirements for your application.

Q: What is the significance of the REACH status difference?

A: The Amphenol ICC SFV21R-1STBE1HLF is listed as REACH affected, meaning it may contain substances of very high concern (SVHC) subject to REACH regulations. Applications subject to REACH compliance requirements should prioritize the Molex or KYOCERA AVX alternatives, which are REACH unaffected.

Q: Can FFC/FCB thickness variations affect connector performance?

A: The IL-FPR-21S-HF-N1 specifies 0.30mm thickness. The Amphenol ICC SFV21R-1STBE1HLF specifies 0.33mm. Thickness tolerance must be verified against cable assembly specifications and connector retention force requirements to ensure proper mechanical engagement.

Q: What is the difference between the Molex and Amphenol ICC substitutes?

A: Both maintain 0.5A per-contact current rating and UL94 V-0 flammability. The Amphenol ICC offers extended operating temperature range (-55°C ~ 105°C vs. -40°C ~ 85°C). The Molex includes solder retention feature and is REACH unaffected. Select based on temperature requirements and regulatory compliance needs.
