Substitute Part Grouping Explanation

Substitution eligibility for the DME6P12K is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must satisfy the following criteria:

Electrical Parameters (Non-negotiable):

  • Capacitance value: 0.12 µF (exact match)
  • DC voltage rating: 630V (exact match)
  • AC voltage rating: 250V (exact match)
  • Tolerance: ±10% (exact match)
  • Dielectric material: Polyester, Metallized (exact match)

Mechanical Parameters (Non-negotiable):

  • Package type: Radial (exact match)
  • Lead spacing: 0.591" / 15.00mm (exact match)
  • Physical dimensions: 0.728" L x 0.256" W / 18.50mm x 6.50mm (exact match)
  • Maximum seated height: 0.571" / 14.50mm (exact match)

Environmental Parameters (Non-negotiable):

  • Operating temperature range: -55°C ~ 125°C (exact match)

The DME6P12K-F meets all substitution criteria as a direct equivalent within the same manufacturer series.

Engineering Selection Recommendations

Primary Recommendation: DME6P12K-F

The DME6P12K-F is the direct active production equivalent of the obsolete DME6P12K. Selection of the DME6P12K-F is based on the following factors:

  1. Product Status: The DME6P12K-F carries Active status, ensuring continued availability and manufacturer support, whereas the DME6P12K is Obsolete with finite stock.

  2. Regulatory Compliance: The DME6P12K-F is ROHS3 Compliant, meeting current environmental and regulatory requirements. The original DME6P12K is RoHS non-compliant, which may present procurement restrictions in regulated markets.

  3. Electrical and Mechanical Equivalence: All electrical parameters (capacitance, voltage ratings, tolerance, dielectric material, temperature range) and mechanical parameters (package type, dimensions, lead spacing, termination) are identical between the two parts.

  4. Inventory Availability: The DME6P12K-F maintains higher current inventory (772 Pcs) compared to the obsolete part (709 Pcs), supporting long-term supply chain reliability.

For new designs or component refresh cycles, the DME6P12K-F is the appropriate selection. For legacy systems requiring the original part number, the DME6P12K remains available from current stock.

Frequently Asked Questions (FAQ)

Q: Can the DME6P12K-F be used as a direct replacement for the DME6P12K in existing designs?

A: Yes. The DME6P12K-F is electrically and mechanically identical to the DME6P12K. All electrical specifications (0.12 µF, 630V DC, 250V AC, ±10% tolerance) and physical dimensions (lead spacing, package size, height) are equivalent. Direct substitution on PCBs designed for the DME6P12K is supported.

Q: What is the difference between the DME6P12K and DME6P12K-F?

A: The primary differences are product status and regulatory compliance. The DME6P12K is Obsolete and RoHS non-compliant, while the DME6P12K-F is Active production and ROHS3 Compliant. All electrical and mechanical specifications are identical.

Q: Does the RoHS3 compliance of the DME6P12K-F affect circuit performance?

A: No. RoHS3 compliance is a regulatory and environmental designation related to material composition and manufacturing processes. It does not alter the electrical performance, capacitance value, voltage rating, or temperature characteristics of the component.

Q: Are there any lead spacing or PCB hole compatibility issues when substituting the DME6P12K-F?

A: No. Both parts have identical lead spacing of 0.591" (15.00mm) and identical radial package configuration. PCBs designed for the DME6P12K will accommodate the DME6P12K-F without modification.

Q: What is the maximum operating temperature for these capacitors?

A: Both the DME6P12K and DME6P12K-F operate across the temperature range of -55°C to 125°C. This specification is identical for both parts.

Q: Can these capacitors be used in AC applications?

A: Yes. Both parts carry an AC voltage rating of 250V, in addition to the 630V DC rating. The AC rating defines the maximum AC voltage that can be applied across the capacitor.

Q: Is the DME6P12K still available for purchase?

A: The DME6P12K is classified as Obsolete. Current inventory of 709 pieces is available from existing stock, but future availability is not guaranteed. For new procurements, the DME6P12K-F (Active status) is recommended.
