150224K400FE Film Capacitor Equivalent & Substitute Parts

Part Overview

The 150224K400FE is a 0.22 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the 150 series. This axial through-hole component operates at 400V DC with polyester metallized dielectric construction. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when inventory requirements necessitate alternative stock sources.

Key Parameters

RoHS Status	ROHS3 Compliant	Important - regulatory requirement

Substitute Part Grouping Explanation

Substitution of the 150224K400FE is permissible with parts meeting the following criteria:

Mandatory Matching Parameters:

Capacitance value: 0.22 µF (no deviation)
Voltage rating: 400V DC minimum
Tolerance: ±10% or tighter
Dielectric type: Polyester, Metallized
Mounting configuration: Through Hole, Axial package
Operating temperature range: -55°C to 125°C minimum

Compliance Requirements:

ROHS3 compliance status
Moisture sensitivity level: 1 (Unlimited)
Termination type: PC Pins

The WMF4P22K-F from Cornell Dubilier Electronics qualifies as a direct substitute based on matching all mandatory electrical parameters and compliance certifications. Physical dimensions differ between the two parts; however, both are axial through-hole configurations suitable for standard PCB layouts.

Engineering Selection Recommendations

Primary Selection: 150224K400FE

The 150224K400FE is the specified component and should be used when available. This part is active in production with 694 units in current inventory stock.

Substitute Selection: WMF4P22K-F

The WMF4P22K-F qualifies as a direct electrical and functional substitute. Both parts are manufactured by Cornell Dubilier Electronics and share identical electrical specifications: 0.22 µF capacitance, 400V DC rating, ±10% tolerance, polyester dielectric, and -55°C to 125°C operating range. Both parts carry ROHS3 compliance and unlimited moisture sensitivity rating.

Physical Dimension Consideration:

The WMF4P22K-F has a larger axial form factor (0.594" diameter × 1.374" length) compared to the 150224K400FE (0.335" diameter × 1.102" length). PCB layout space availability must be verified before substitution. Both parts use identical through-hole axial mounting and PC pin termination, ensuring compatibility with standard PCB footprints designed for axial film capacitors.

Inventory Status:

WMF4P22K-F has 822 units in current stock, providing an alternative sourcing option when 150224K400FE inventory is depleted.

Frequently Asked Questions (FAQ)

Q: Can WMF4P22K-F replace 150224K400FE in all applications?

A: Yes, from an electrical standpoint. Both parts have identical capacitance (0.22 µF), voltage rating (400V DC), tolerance (±10%), operating temperature range (-55°C to 125°C), and dielectric material (polyester). Physical dimensions differ; verify PCB layout space accommodates the larger WMF4P22K-F form factor (0.594" diameter vs. 0.335" diameter).

Q: What are the key parameters that determine substitutability?

A: Capacitance value, DC voltage rating, tolerance, dielectric type, mounting configuration (through-hole axial), and operating temperature range are the critical parameters. Both parts match on all these criteria. Compliance certifications (ROHS3, MSL 1) are also identical.

Q: Are there physical compatibility issues with substitution?

A: The WMF4P22K-F is physically larger in diameter and length. Standard axial through-hole PCB footprints accommodate both sizes; however, space-constrained layouts may require verification. Lead spacing and termination type (PC Pins) are identical for both parts.

Q: Do both parts have the same regulatory compliance?

A: Yes. Both 150224K400FE and WMF4P22K-F are ROHS3 compliant, REACH unaffected, and carry ECCN EAR99 classification. Moisture sensitivity level is 1 (Unlimited) for both parts.

Q: Which part should be selected for new designs?

A: Either part is acceptable for new designs based on electrical equivalence. Selection should consider PCB layout constraints and inventory availability. Both parts are active in production.

Q: Is voltage derating required when using either part?

A: No. Both parts are rated for 400V DC operation. Application voltage requirements must not exceed 400V DC for either component.
