Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete DME2S15K is determined by strict equivalence in the following critical parameters:

Direct Equivalence Criteria:

• Capacitance value: 0.015 µF (exact match required)
• Tolerance: ±10% (exact match required)
• Dielectric material: Polyester, Metallized (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial (exact match required)
• Lead spacing: 0.295" (7.50mm) (exact match required)
• Termination: PC Pins (exact match required)
• Operating temperature range: -55°C to 125°C (exact match required)

Voltage Rating Substitution Logic: Substitute parts may operate at equal or higher voltage ratings than the original specification. A component rated for higher voltage can replace one rated for lower voltage in the same circuit application, provided all other parameters remain identical.

Parameter Comparison

Engineering Selection Recommendations

DME2S15K-F (Direct Equivalent): This part provides direct functional equivalence to the obsolete DME2S15K. All electrical and mechanical parameters are identical. The primary advantage is active product status and ROHS3 compliance, making it suitable for new designs and procurement where regulatory compliance is required. This is the preferred replacement for direct substitution.

DME4S15K-F (Voltage Upgrade): This part maintains identical capacitance, tolerance, dielectric material, mounting configuration, and thermal operating range. The voltage rating is elevated to 400V DC (200V AC), representing a 60% increase over the original specification. Physical dimensions show minor variation in width (0.173" versus 0.177"), remaining within standard PCB layout tolerances. This component is suitable for applications where higher voltage margin is beneficial or required. Active product status and ROHS3 compliance are confirmed.

Both substitute parts are manufactured by Cornell Dubilier Electronics within the DME series, ensuring design continuity and supply chain consistency.

Frequently Asked Questions (FAQ)

Q: Can DME2S15K-F be used as a direct replacement for DME2S15K?

A: Yes. The DME2S15K-F is electrically and mechanically identical to the obsolete DME2S15K. All parameters including capacitance, tolerance, voltage rating, dielectric material, mounting type, package configuration, and lead spacing are equivalent. The primary difference is active product status and ROHS3 compliance.

Q: What is the difference between DME2S15K-F and DME4S15K-F?

A: Both parts share identical capacitance (0.015 µF), tolerance (±10%), dielectric material (polyester metallized), mounting type (through hole radial), and thermal operating range (-55°C to 125°C). The DME4S15K-F features elevated voltage ratings: 400V DC and 200V AC, compared to 250V DC and 160V AC for the DME2S15K-F. Physical width differs slightly (0.173" versus 0.177"), with all other dimensions and lead spacing remaining identical.

Q: Can DME4S15K-F replace DME2S15K in a 250V DC circuit?

A: Yes. The DME4S15K-F is rated for 400V DC, which exceeds the 250V DC requirement of the original circuit. A component with higher voltage rating can be substituted for one with lower voltage rating when all other parameters are compatible.

Q: Are there any PCB layout considerations when substituting these parts?

A: Lead spacing remains constant at 0.295" (7.50mm) across all three parts, ensuring direct PCB compatibility. The DME4S15K-F shows a minor width reduction (0.173" versus 0.177"), which does not affect through-hole mounting or standard PCB layouts.

Q: What is the RoHS compliance status of these parts?

A: The original DME2S15K is RoHS non-compliant. Both substitute parts, DME2S15K-F and DME4S15K-F, are ROHS3 compliant, meeting current regulatory requirements for new designs and procurement.

Q: Are these parts suitable for high-temperature applications?

A: All three parts operate across the identical temperature range of -55°C to 125°C, confirming suitability for applications within this thermal envelope.
