DMM2W1P5K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DMM2W1P5K-F is a 1.5 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 250V DC voltage rating and ±10% tolerance. This radial through-hole component utilizes polyester metallized dielectric technology and operates across a temperature range of -55°C to 125°C. The part maintains Active product status with ROHS3 compliance and is currently in stock with 808 units available.

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 within acceptable electrical boundaries.

Key Parameters

Substitute Part Grouping Explanation

Substitute relationships for the DMM2W1P5K-F are established based on the following criteria:

Direct Substitutes (Identical Electrical Specifications): Parts that maintain the same capacitance value (1.5 µF), tolerance (±10%), voltage rating (250V DC / 160V AC), dielectric material (polyester metallized), operating temperature range (-55°C to 125°C), and mounting configuration (through-hole radial with PC pins) are classified as direct substitutes.

Functional Equivalents (Higher Voltage Rating): The DME4W1P5K-F operates at 400V DC / 200V AC with identical capacitance and tolerance specifications. This part functions as an electrical equivalent in circuits designed for the 250V rating, as it provides superior voltage margin while maintaining all other electrical and mechanical parameters within acceptable substitution boundaries.

Similar Alternatives (Dimensional Variation): The B32522C3155K000 matches the electrical specifications (1.5 µF, ±10%, 250V DC / 160V AC, polyester metallized) and operating temperature range but incorporates different physical dimensions and lead spacing. This component is classified as a similar alternative where circuit board layout permits accommodation of different footprint geometry.

Parameter Comparison

Engineering Selection Recommendations

DME4W1P5K-F Selection Criteria: The DME4W1P5K-F is suitable for direct substitution in applications where the circuit design accommodates the 400V DC rating. This part maintains identical capacitance, tolerance, and operating temperature specifications while providing increased voltage margin. Both components are manufactured by Cornell Dubilier Electronics, share the same series design lineage, and maintain identical lead spacing (1.083"). Both parts are ROHS3 compliant and Active status. Dimensional differences are minimal (height variation of 0.020" / 0.50mm). This substitute is appropriate when higher voltage headroom is beneficial or when inventory of the DMM2W1P5K-F is constrained.

B32522C3155K000 Selection Criteria: The B32522C3155K000 provides electrical equivalence with identical capacitance, tolerance, and voltage ratings. This EPCOS - TDK Electronics component is ROHS3 compliant and Active status with significantly higher inventory availability (9133 units). Selection of this substitute requires verification that the reduced physical dimensions and different lead spacing (0.591" versus 1.083") are compatible with the target circuit board layout. The stacked metallized construction represents a different manufacturing approach within the polyester film category. This substitute is appropriate for applications where board space is constrained or where lead spacing accommodation is feasible.

Frequently Asked Questions (FAQ)

Q: Can the DME4W1P5K-F be used in place of the DMM2W1P5K-F without circuit modification?

A: The DME4W1P5K-F maintains identical electrical specifications for capacitance (1.5 µF), tolerance (±10%), and operating temperature range (-55°C to 125°C). The 400V DC rating provides compatibility with circuits designed for 250V DC operation. Lead spacing is identical (1.083"), and physical dimensions are comparable. No circuit modification is required from an electrical standpoint. Mechanical mounting verification is recommended due to minor dimensional variations.

Q: What are the key differences between the DMM2W1P5K-F and B32522C3155K000?

A: Both components provide identical electrical performance: 1.5 µF capacitance, ±10% tolerance, 250V DC / 160V AC rating, and -55°C to 125°C operating range. Primary differences are: (1) Manufacturer - Cornell Dubilier Electronics versus EPCOS - TDK Electronics; (2) Lead spacing - 1.083" versus 0.591"; (3) Physical dimensions - the B32522C3155K000 is significantly smaller; (4) Dielectric construction - stacked metallized versus standard metallized polyester. Selection depends on circuit board layout constraints and lead spacing compatibility.

Q: Are all three parts ROHS3 compliant?

A: Yes. The DMM2W1P5K-F, DME4W1P5K-F, and B32522C3155K000 are all ROHS3 compliant. All three components are also REACH unaffected and classified under ECCN EAR99 with HTSUS code 8532.25.0070.

Q: What is the significance of the different lead spacing values?

A: Lead spacing determines the distance between the two PC pins on the circuit board. The DMM2W1P5K-F and DME4W1P5K-F both use 1.083" (27.50mm) spacing, making them mechanically interchangeable on the same board layout. The B32522C3155K000 uses 0.591" (15.00mm) spacing, requiring different board hole positioning. Lead spacing compatibility must be verified before selecting the B32522C3155K000 as a substitute.

Q: Can the B32522C3155K000 be used in automotive applications?

A: The B32522C3155K000 is rated for automotive applications and carries AEC-Q200 qualification. The DMM2W1P5K-F and DME4W1P5K-F are specified for general purpose applications without automotive qualification. If automotive compliance is required, the B32522C3155K000 is the appropriate selection among the three options.

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

A: The DMM2W1P5K-F has MSL 1 (Unlimited), indicating no moisture sensitivity restrictions. The DME4W1P5K-F and B32522C3155K000 are listed as Not Applicable for MSL, indicating these components do not require moisture control during storage or handling.
