DMM1P47K-F Equivalent & Substitute Parts Reference

Part Overview

The DMM1P47K-F is a 0.47 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 100V DC voltage rating and ±10% tolerance. This radial through-hole component operates across the temperature range of -55°C to 125°C and is constructed with polyester metallized dielectric material. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter constraints of the application circuit. Alternative components may be required due to inventory availability, lead time considerations, or design optimization for higher voltage applications.

Engineering Selection Recommendations

Direct PCB Replacement (0.591" Lead Spacing):

The DME2P47K-F, B32522C3474J000, and B32522C3474K000 maintain identical lead spacing (15.00 mm / 0.591 inches) and can be directly substituted on PCBs designed for the DMM1P47K-F without layout modifications. These parts offer upgraded voltage ratings (250V DC) while maintaining the same capacitance and tolerance specifications. All three parts maintain Active product status and ROHS3 compliance.

Voltage Upgrade Path:

When circuit design permits higher voltage operation, the DME2P47K-F (CDE series) or B32522C3474K000 (EPCOS-TDK series) provide 250V DC rating with ±10% tolerance matching the original specification. The B32522C3474J000 offers tighter ±5% tolerance at the same 250V rating for applications requiring improved capacitance accuracy.

Alternative Footprint (0.921" Lead Spacing):

The DMT1P47K-F maintains equivalent electrical specifications (0.47 µF, ±10%, 100V DC) but requires different PCB hole spacing (23.40 mm / 0.921 inches). This part is suitable only when PCB layout accommodates the larger lead spacing.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and operate across the -55°C to 125°C temperature range. The EPCOS-TDK parts (B32522C3474J000 and B32522C3474K000) carry AEC-Q200 automotive qualification, suitable for automotive and EMI/RFI suppression applications.

Frequently Asked Questions (FAQ)

Q: Can the DME2P47K-F replace the DMM1P47K-F directly on the PCB?

A: Yes. The DME2P47K-F maintains identical lead spacing (15.00 mm), capacitance (0.47 µF), tolerance (±10%), and termination type (PC Pins). The higher voltage rating (250V DC versus 100V DC) does not prevent direct substitution and provides design margin for voltage transients.

Q: What is the difference between the CDE and EPCOS-TDK substitute parts?

A: Both manufacturers provide equivalent electrical performance at 0.47 µF, 250V DC with matching lead spacing. The EPCOS-TDK parts (B32522C3474J000 and B32522C3474K000) include AEC-Q200 automotive qualification and employ metallized-stacked dielectric construction. The B32522C3474J000 offers ±5% tolerance versus ±10% for other parts.

Q: Why is the DMT1P47K-F listed as a substitute if it has different lead spacing?

A: The DMT1P47K-F is classified as a similar substitute based on identical electrical specifications (0.47 µF, ±10%, 100V DC, -55°C to 125°C). However, the 23.40 mm lead spacing requires PCB redesign and is not a direct replacement. This part is suitable only when circuit layout can accommodate the larger footprint.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts (DME2P47K-F, DMT1P47K-F, B32522C3474J000, B32522C3474K000) maintain ROHS3 compliance and are suitable for applications requiring environmental compliance certification.

Q: What is the moisture sensitivity level (MSL) for the substitute parts?

A: The DMM1P47K-F carries MSL 1 (Unlimited). The CDE substitute (DME2P47K-F) and EPCOS-TDK substitutes (B32522C3474J000, B32522C3474K000) are listed as Not Applicable for MSL, indicating no moisture sensitivity restrictions during storage or handling.

Q: Can I use a 250V rated capacitor in a 100V circuit?

A: Yes. A higher voltage-rated capacitor operates safely in lower voltage applications. The 250V rated substitutes (DME2P47K-F, B32522C3474J000, B32522C3474K000) function correctly in circuits designed for 100V operation and provide additional voltage margin for transient protection.

Q: What is the difference between ±5% and ±10% tolerance?

A: Tolerance specifies the allowable deviation from the nominal 0.47 µF capacitance value. ±5% tolerance (B32522C3474J000) restricts capacitance to 0.4465–0.4935 µF, while ±10% tolerance allows 0.423–0.517 µF. Applications requiring tighter capacitance accuracy should specify the ±5% part.
