Substitute Part Grouping Explanation

Substitute parts for the DME2W1P5K-F are identified based on strict electrical and mechanical parameter equivalence. The substitution logic requires:

Electrical Parameter Matching:

• Capacitance value: 1.5 µF (exact match required)
• Tolerance: ±10% (substitute must meet or exceed this specification)
• DC voltage rating: 250V minimum (substitute must equal or exceed)
• AC voltage rating: 160V minimum (substitute must equal or exceed)
• Dielectric material: Polyester, metallized construction (functional equivalence)
• Operating temperature range: -55°C to 125°C (substitute must cover this range)

Mechanical Parameter Matching:

• Mounting type: Through hole (required for PCB assembly compatibility)
• Package configuration: Radial (required for physical form factor)
• Lead spacing: 0.591" / 15.00mm (required for PCB footprint compatibility)
• Termination: PC pins (required for soldering compatibility)

Compliance Requirements:

• RoHS3 compliance status (regulatory requirement)
• REACH unaffected status (regulatory requirement)
• ECCN and HTSUS classifications (trade compliance)

The B32522C3155K000 from EPCOS - TDK Electronics meets all critical substitution criteria and is classified as a direct equivalent.

Engineering Selection Recommendations

Direct Substitution Criteria Met:

The B32522C3155K000 qualifies as a direct substitute for the DME2W1P5K-F based on the following engineering factors:

1. Electrical Equivalence: All critical electrical parameters match exactly, including capacitance (1.5 µF), tolerance (±10%), voltage ratings (250V DC / 160V AC), and operating temperature range (-55°C to 125°C).

2. Mechanical Compatibility: Lead spacing (15.00mm), mounting type (through hole), package configuration (radial), and termination method (PC pins) are identical, ensuring direct PCB footprint compatibility without layout modifications.

3. Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, satisfying environmental and trade regulatory requirements.

4. Product Status: Both parts maintain active product status with established supply chains and manufacturing continuity.

5. Dielectric Material: The B32522C3155K000 uses polyester (PET) metallized construction with stacked configuration, which is functionally equivalent to the DME2W1P5K-F polyester metallized design for general-purpose applications.

6. Physical Dimensions: Minor dimensional variations (0.5mm length difference, 0.5mm width difference, 1.5mm height difference) remain within standard PCB assembly tolerances and do not affect circuit performance or board layout compatibility.

Selection Basis:

Component selection should be based on availability, lead time, and cost considerations. Both parts are suitable for direct substitution in applications requiring 1.5 µF film capacitors at 250V DC operating voltage with general-purpose performance characteristics.
