WMF1P47K Equivalent & Substitute Parts

Part Overview

The WMF1P47K is a 0.47 µF film capacitor rated for 100V DC operation with polyester dielectric material and axial through-hole mounting. Manufactured by Cornell Dubilier Electronics (CDE), this component is classified as obsolete product status. Due to its obsolete designation, identifying equivalent substitute parts with identical electrical and mechanical specifications is necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the WMF1P47K is determined by strict equivalence across the following critical parameters:

• Capacitance Value: 0.47 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating (DC): 100V (exact match required)
• Dielectric Material: Polyester (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Axial (exact match required)
• Physical Dimensions: 0.492" Dia x 1.248" L / 12.50mm x 31.70mm (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Termination: PC Pins (exact match required)

The WMF1P47K-F meets all substitution criteria as a direct equivalent within the same WMF series from Cornell Dubilier Electronics.

Parameter Comparison

Engineering Selection Recommendations

The WMF1P47K-F serves as the direct substitute for the obsolete WMF1P47K. Both components are manufactured by Cornell Dubilier Electronics within the WMF series and share identical electrical and mechanical specifications across all critical parameters including capacitance, voltage rating, dielectric material, physical dimensions, and operating temperature range.

The primary distinction between these parts is product status and regulatory compliance. The WMF1P47K is classified as obsolete, while the WMF1P47K-F maintains active product status. Additionally, the WMF1P47K-F achieves ROHS3 compliance, whereas the WMF1P47K is RoHS non-compliant. Both components maintain REACH Unaffected status and share identical ECCN (EAR99) and HTSUS (8532.25.0010) classifications.

For new designs and ongoing procurement, the WMF1P47K-F is the appropriate selection due to its active availability and enhanced regulatory compliance posture.

Frequently Asked Questions (FAQ)

Q: Can the WMF1P47K-F be used as a direct replacement for the WMF1P47K in existing applications?

A: Yes. The WMF1P47K-F is electrically and mechanically equivalent to the WMF1P47K. All critical parameters including capacitance (0.47 µF), voltage rating (100V DC), tolerance (±10%), dielectric material (polyester), physical dimensions (0.492" Dia x 1.248" L), and operating temperature range (-55°C ~ 125°C) are identical. Both components feature axial through-hole mounting with PC pin termination.

Q: What is the difference between WMF1P47K and WMF1P47K-F?

A: The electrical and mechanical specifications are identical. The differences are: (1) Product Status—WMF1P47K is obsolete while WMF1P47K-F is active; (2) RoHS Compliance—WMF1P47K is RoHS non-compliant while WMF1P47K-F is ROHS3 compliant; (3) Packaging—WMF1P47K uses standard packaging while WMF1P47K-F is supplied in bulk packaging.

Q: Are there any physical or dimensional differences between these parts?

A: No. Both the WMF1P47K and WMF1P47K-F share identical physical dimensions of 0.492" diameter by 1.248" length (12.50mm x 31.70mm). They are both axial through-hole components with PC pin termination and fit the same PCB footprint.

Q: What is the operating temperature range for these capacitors?

A: Both the WMF1P47K and WMF1P47K-F operate across the temperature range of -55°C to 125°C, providing consistent performance across industrial and commercial applications.

Q: Are these components suitable for general-purpose applications?

A: Yes. Both the WMF1P47K and WMF1P47K-F are rated for general-purpose applications. The 0.47 µF capacitance value with 100V DC rating and polyester dielectric material support standard filtering, coupling, and decoupling functions in electronic circuits.

Q: What is the moisture sensitivity level (MSL) for these capacitors?

A: Both components have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
