Substitute Part Grouping Explanation

Substitute parts for the DMM6P22K-F are classified into two categories based on electrical and mechanical compatibility:

Upgrade Category (Higher Voltage Rating): The DME10P22K-F represents an electrical upgrade with identical capacitance (0.22 µF), tolerance (±10%), and AC voltage rating (250V), but with an elevated DC voltage rating of 1000V (1kV) compared to the original 630V. This part maintains the same lead spacing (0.886" / 22.50mm) and through-hole radial package, ensuring PCB footprint compatibility. The upgrade is suitable for applications requiring higher voltage margin or operating in elevated voltage environments.

Direct Equivalent Category (Matching Specifications): The DME6P22K-F (Cornell Dubilier Electronics) and QXK2J224KTPTZH (Nichicon) are direct electrical equivalents with identical capacitance (0.22 µF), tolerance (±10%), and voltage ratings (250V AC / 630V DC). Both maintain polyester metallized dielectric construction and through-hole radial mounting. The DME6P22K-F features a smaller physical footprint (18.50mm x 9.50mm, 15.00mm lead spacing) compared to the original part. The QXK2J224KTPTZH maintains the original lead spacing (22.50mm) but with a narrower width (8.90mm) and operates within -40°C to 105°C temperature range.

Substitution eligibility is determined by: matching capacitance value, equal or tighter tolerance, equal or higher voltage ratings, identical dielectric material, compatible mounting type, and PCB footprint accommodation (lead spacing and physical dimensions).

Parameter Comparison

Engineering Selection Recommendations

DME10P22K-F Selection Criteria: Select the DME10P22K-F when the application circuit operates at or near 630V DC and requires additional voltage safety margin. The 1000V DC rating provides 370V headroom above the original specification. This part maintains identical lead spacing (22.50mm) and is a direct PCB footprint replacement. Height increase from 20.00mm to 23.00mm and width increase from 11.00mm to 12.00mm must be verified against available board space. All regulatory certifications (ROHS3, REACH Unaffected, EAR99) are maintained. This upgrade is suitable for high-reliability applications or designs operating in elevated voltage environments.

DME6P22K-F Selection Criteria: Select the DME6P22K-F when space constraints require a smaller footprint. This part provides identical electrical specifications (0.22 µF, ±10%, 250V AC / 630V DC) with reduced physical dimensions (18.50mm x 9.50mm versus 26.00mm x 11.00mm). The lead spacing reduces from 22.50mm to 15.00mm, requiring PCB footprint redesign. Higher inventory availability (16,310 units) supports supply chain continuity. All regulatory certifications are maintained. This selection is appropriate for compact designs where the reduced lead spacing accommodates the PCB layout.

QXK2J224KTPTZH Selection Criteria: Select the QXK2J224KTPTZH when cross-manufacturer sourcing is required or when supply from Cornell Dubilier Electronics is constrained. This Nichicon part maintains identical electrical specifications and lead spacing (22.50mm), enabling direct PCB footprint compatibility without redesign. Operating temperature range (-40°C to 105°C) is narrower than the original (-55°C to 125°C); verify application temperature requirements do not exceed 105°C. Physical dimensions (26.00mm x 8.90mm) differ slightly in width. All regulatory certifications are maintained. This selection supports supply chain diversification and alternative sourcing strategies.

Frequently Asked Questions (FAQ)

Q: Can the DME10P22K-F be used as a direct replacement for the DMM6P22K-F?

A: The DME10P22K-F is electrically compatible with identical capacitance (0.22 µF), tolerance (±10%), and AC voltage rating (250V). The elevated DC voltage rating (1000V versus 630V) does not prevent substitution in circuits designed for 630V operation. Lead spacing remains identical (22.50mm), ensuring PCB footprint compatibility. Physical dimensions increase slightly (height 23.00mm versus 20.00mm, width 12.00mm versus 11.00mm); verify available board space before selection.

Q: What is the primary difference between the DME6P22K-F and the original DMM6P22K-F?

A: Both parts share identical electrical specifications (0.22 µF, ±10%, 250V AC / 630V DC, polyester metallized dielectric). The DME6P22K-F features a smaller physical footprint (18.50mm x 9.50mm) with reduced lead spacing (15.00mm versus 22.50mm). This dimensional reduction requires PCB footprint modification and cannot be used as a direct drop-in replacement without board redesign. The DME6P22K-F offers higher inventory availability (16,310 units).

Q: Is the QXK2J224KTPTZH suitable for applications requiring -55°C operation?

A: No. The QXK2J224KTPTZH operates within -40°C to 105°C, which does not encompass the -55°C lower temperature limit of the original DMM6P22K-F (-55°C to 125°C). Applications requiring operation below -40°C must use the DMM6P22K-F, DME10P22K-F, or DME6P22K-F, all of which support -55°C minimum temperature.

Q: Can lead spacing differences affect circuit performance?

A: Lead spacing affects PCB footprint compatibility and mechanical mounting only. Electrical performance is not affected by lead spacing differences. The DME6P22K-F (15.00mm spacing) requires PCB redesign compared to the original 22.50mm spacing. The DME10P22K-F and QXK2J224KTPTZH maintain 22.50mm spacing and are direct PCB replacements without layout modification.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. The DMM6P22K-F, DME10P22K-F, DME6P22K-F, and QXK2J224KTPTZH are all ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and use.

Q: Which substitute part offers the best supply availability?

A: The DME6P22K-F offers the highest inventory level with 16,310 units in stock, compared to 1,715 units for the DME10P22K-F, 1,103 units for the QXK2J224KTPTZH, and 769 units for the original DMM6P22K-F. Supply chain considerations may favor the DME6P22K-F for high-volume production, provided PCB footprint redesign is acceptable.
