Substitute Part Grouping Explanation

Substitution relationships for the DME2P47K-F are established based on strict equivalence of core electrical and mechanical parameters. All substitute parts must maintain identical capacitance (0.47 µF), voltage ratings (250V DC / 160V AC), operating temperature range (-55°C to 125°C), dielectric material type (polyester metallized), mounting configuration (through hole radial), and termination style (PC pins).

The substitute parts are categorized as follows:

Direct Substitutes - Parts with identical electrical specifications and compatible mechanical dimensions for pin-compatible replacement.

Upgrade Substitutes - Parts with superior tolerance specifications (±5% vs ±10%) while maintaining all other electrical and mechanical parameters.

Similar Substitutes - Parts with modified physical dimensions and lead spacing that require board layout verification prior to installation.

Engineering Selection Recommendations

All substitute parts maintain ROHS3 compliance and are classified as Active products. The EPCOS - TDK Electronics B3252* series parts include AEC-Q200 automotive ratings, which provide additional qualification and reliability documentation for applications requiring automotive-grade components.

For designs requiring direct physical compatibility with existing DME2P47K-F PCB layouts, B32522C3474K000 and B32522C3474J000 are preferred due to identical lead spacing (0.591" / 15.00mm). The B32522C3474J000 offers superior tolerance specification (±5%) compared to the original ±10% specification.

For applications where physical footprint constraints allow lead spacing modification, B32521C3474K000 and B32521C3474K189 provide compact alternatives with 0.394" (10.00mm) lead spacing and reduced height profiles. B32521C3474K189 is supplied in Cut Tape (CT) packaging, whereas B32521C3474K000 is supplied in Bulk packaging.

Frequently Asked Questions (FAQ)

Q: Can B32522C3474K000 replace DME2P47K-F directly on the PCB? A: Yes. B32522C3474K000 shares identical electrical specifications, lead spacing (0.591" / 15.00mm), and termination type (PC Pins). Physical dimensions are slightly reduced (0.709" vs 0.728" length; 0.433" vs 0.551" height), which provides design flexibility without requiring PCB layout modifications.

Q: What is the difference between B32522C3474K000 and B32522C3474J000? A: Both parts share identical electrical characteristics, dimensions, and lead spacing. B32522C3474J000 provides superior tolerance specification of ±5% compared to B32522C3474K000's ±10%. This tighter tolerance allows for more precise capacitance values in critical filtering and timing applications.

Q: Can B32521C3474K000 or B32521C3474K189 be used as replacements? A: These parts share all critical electrical specifications but feature different mechanical dimensions and lead spacing (0.394" vs 0.591"). They require board layout verification and hole repositioning on the PCB prior to installation. B32521C3474K189 is supplied in Cut Tape (CT) packaging, while B32521C3474K000 is supplied in Bulk.

Q: Are all substitute parts ROHS3 compliant? A: Yes. The DME2P47K-F and all EPCOS - TDK Electronics substitute parts are ROHS3 compliant.

Q: Do the EPCOS substitute parts carry automotive certifications? A: Yes. All EPCOS - TDK Electronics B3252* series substitute parts are rated AEC-Q200, designating qualification for automotive applications. The original DME2P47K-F does not carry this designation.
