IL-FPR-40S-HF-N1 Equivalent & Substitute Parts

Part Overview

The IL-FPR-40S-HF-N1 is a 40-position FPC (Flat Flexible Connector) manufactured by JAE Electronics, designed for surface mount, right-angle applications with bottom contacts and 0.50mm 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-40S-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-40S-HF-N1 is determined by strict alignment of the following critical parameters:

• Connector Type & Configuration: FPC connector with 40 positions, bottom contacts, surface mount right-angle orientation
• Electrical Specifications: 0.50mm pitch, 50V voltage rating, 0.5A per contact current capacity
• Mechanical Interface: Solder termination, slide lock retention, Zero Insertion Force operation
• Environmental Compliance: UL94 V-0 flammability rating, MSL 1 moisture sensitivity

The substitute part 62684-401100ALF (Amphenol ICC) meets all critical substitution criteria. While secondary parameters such as housing material, actuator material, and contact material composition differ, these variations remain within acceptable engineering tolerances for FPC connector applications and do not compromise functional compatibility.

Engineering Selection Recommendations

The 62684-401100ALF (Amphenol ICC) is a direct functional substitute for the obsolete IL-FPR-40S-HF-N1. Selection is supported by the following engineering factors:

Electrical & Mechanical Compatibility: All critical electrical parameters (voltage, current, pitch, position count) and mechanical interfaces (surface mount, right angle, solder termination, slide lock) are identical. The substitute connector maintains full functional equivalence for signal integrity and mechanical retention.

Environmental Performance: Both connectors meet UL94 V-0 flammability requirements and MSL 1 moisture sensitivity specifications. The substitute part extends the operating temperature range to -55°C to 85°C, providing enhanced thermal margin compared to the original -40°C to 85°C specification.

Product Availability & Compliance: The IL-FPR-40S-HF-N1 is obsolete with no ongoing manufacturing. The 62684-401100ALF is an active product with confirmed inventory (2652 pcs) and RoHS compliance certification, ensuring long-term supply chain viability and regulatory alignment.

Physical Dimensions: The height above board variance (0.004" / 0.10mm) and FFC thickness compatibility (0.30mm overlap) are within standard PCB layout tolerances and do not require design modification.

Frequently Asked Questions (FAQ)

Q: Can the 62684-401100ALF directly replace the IL-FPR-40S-HF-N1 without PCB redesign?

A: Yes. The 62684-401100ALF maintains identical pitch (0.50mm), position count (40), mounting type (surface mount right angle), and termination method (solder). The 0.004" height variance and compatible FFC thickness do not require PCB layout changes.

Q: What is the difference between copper alloy and phosphor bronze contacts?

A: Both materials provide equivalent electrical conductivity and gold plating compatibility for this connector class. Phosphor bronze offers enhanced spring characteristics and durability in high-cycle applications. For standard FPC applications, both contact materials deliver functionally equivalent performance.

Q: Does the substitute part require different assembly or soldering procedures?

A: No. Both connectors use identical solder termination and slide lock retention mechanisms. Standard surface mount assembly processes apply without modification.

Q: Is the substitute part RoHS compliant?

A: Yes. The 62684-401100ALF is RoHS compliant. The original IL-FPR-40S-HF-N1 RoHS status is not specified in available documentation.

Q: What is the impact of the extended operating temperature range (-55°C to 85°C vs. -40°C to 85°C)?

A: The substitute part's extended lower temperature limit provides additional thermal margin and is fully backward compatible with the original specification. No design changes are required.

Q: Are there packaging differences between the two parts?

A: The IL-FPR-40S-HF-N1 packaging is not specified. The 62684-401100ALF is supplied in Tape & Reel (TR) format, standard for high-volume surface mount production.
