F05E-201146R FPC Connector Equivalent & Substitute Parts

Part Overview

The F05E-201146R is a 20-position flat flexible connector (FPC) manufactured by Harwin Inc., designed for surface mount, right-angle applications with 0.50mm pitch contacts. This connector features top-mounted contacts, slide lock mechanism, and zero insertion force (ZIF) operation. The product is currently obsolete, making equivalent substitute parts necessary for ongoing design support, maintenance, and production continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the F05E-201146R is determined by the following critical parameters:

• Number of Positions: 20 (exact match required)
• Pitch: 0.020" (0.50mm) (exact match required)
• Mounting Type: Surface Mount, Right Angle (exact match required)
• Voltage Rating: 50V (minimum requirement)
• Current Rating: 0.4A minimum (substitute must meet or exceed)
• Operating Temperature Range: -25°C ~ 85°C (substitute must cover or exceed this range)
• FFC, FCB Thickness: 0.30mm (exact match required)
• Height Above Board: 0.079" (2.00mm) (exact match required)
• Material Flammability Rating: UL94 V-0 (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The three substitute parts listed below meet these critical parameters. Variations in contact material, housing material, locking mechanism type, contact finish, and mating cycles are acceptable within the scope of functional equivalence for this connector category.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are active products with ROHS3 compliance and UL94 V-0 flammability ratings, ensuring regulatory alignment with the obsolete F05E-201146R.

68712014022 (Würth Elektronik) provides the closest functional match with identical locking mechanism (slide lock) and matching operating temperature range. This part is recommended as the primary substitute for direct replacement applications.

FH12-20S-0.5SH(55) (Hirose) features bottom-mounted contacts and flip lock mechanism, requiring PCB layout modification. This part offers extended operating temperature range (-40°C ~ 85°C) and is suitable for applications requiring enhanced thermal performance.

FH12A-20S-0.5SH(55) (Hirose) provides top-mounted contacts matching the original F05E-201146R contact orientation, with flip lock mechanism and extended operating temperature range. This part is suitable for applications where contact orientation is critical and thermal performance enhancement is beneficial.

All substitute parts exceed the original 0.4A current rating specification, providing improved electrical capacity. Contact finish differences (tin versus gold) reflect material selection by each manufacturer and do not affect functional compatibility within the specified voltage and current parameters.

Frequently Asked Questions (FAQ)

Q: Can FH12-20S-0.5SH(55) be used as a direct replacement for F05E-201146R?

A: FH12-20S-0.5SH(55) meets all critical electrical and mechanical parameters but features bottom-mounted contacts versus the top-mounted contacts of the original part. PCB layout modification is required. If contact orientation is not critical to your application, this part is functionally equivalent.

Q: What is the difference between FH12-20S-0.5SH(55) and FH12A-20S-0.5SH(55)?

A: Both parts are from the Hirose FH12 series with identical electrical specifications. The primary difference is contact orientation: FH12-20S-0.5SH(55) has bottom-mounted contacts, while FH12A-20S-0.5SH(55) has top-mounted contacts. FH12A-20S-0.5SH(55) provides closer mechanical compatibility with the original F05E-201146R.

Q: Are the substitute parts available in the same packaging as the original?

A: No. The original F05E-201146R packaging is not specified in available data. Substitute parts are available in different packaging: 68712014022 in Tape & Reel (TR), FH12-20S-0.5SH(55) in Cut Tape (CT) & Digi-Reel®, and FH12A-20S-0.5SH(55) in Tape & Reel (TR). Packaging selection should be based on your procurement and assembly requirements.

Q: Do all substitute parts meet the same compliance standards?

A: Yes. All three substitute parts are ROHS3 compliant, UL94 V-0 rated, and have MSL 1 (Unlimited) moisture sensitivity levels, matching the original F05E-201146R compliance profile.

Q: What is the impact of different locking mechanisms (slide lock versus flip lock)?

A: Locking mechanism type affects insertion and removal procedures but does not impact electrical or thermal performance. Slide lock (68712014022) and flip lock (Hirose parts) both provide zero insertion force (ZIF) operation. Selection depends on your assembly process and connector handling requirements.

Q: Can I use 68712014022 as a drop-in replacement?

A: 68712014022 provides the closest functional match with identical contact orientation (top-mounted), matching locking mechanism (slide lock), and equivalent operating temperature range. This part is suitable for drop-in replacement applications without PCB layout modification.
