DME6S22K-F Equivalent & Substitute Parts Reference

Part Overview

The DME6S22K-F is a 0.022 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) with a 630V DC voltage rating and ±10% tolerance. This polyester metallized radial capacitor is designed for general-purpose applications and operates across a temperature range of -55°C to 125°C. The part is currently active in production with 1045 units in stock and maintains full ROHS3 compliance and REACH unaffected status.

Equivalent and substitute parts are identified when design requirements permit voltage rating upgrades, tolerance improvements, or dimensional variations while maintaining the same capacitance value and core electrical characteristics.

Substitute Part Grouping Explanation

Substitute parts for the DME6S22K-F are classified into two categories based on allowed parameter variations:

Category 1: Same Voltage Rating (630V DC) with Tolerance Improvement

• Part: B32521N8223J000 (EPCOS - TDK Electronics)
• Substitution Logic: Identical capacitance (0.022 µF), identical DC voltage rating (630V), improved tolerance (±5% vs ±10%), same dielectric type (polyester metallized), same mounting configuration (through-hole radial), same operating temperature range (-55°C to 125°C), and equivalent lead spacing (0.394")
• This substitute provides tighter tolerance specification while maintaining all critical electrical parameters

Category 2: Voltage Rating Upgrade (1000V DC)

• Part: DME10S22K-F (Cornell Dubilier Electronics)
• Substitution Logic: Identical capacitance (0.022 µF), identical tolerance (±10%), same dielectric type (polyester metallized), same mounting configuration (through-hole radial), same operating temperature range (-55°C to 125°C), and same manufacturer series (DME). The DC voltage rating is upgraded from 630V to 1000V (1kV), which is permitted in applications where higher voltage margin is required
• Physical dimensions and lead spacing increase proportionally to accommodate higher voltage rating

Engineering Selection Recommendations

B32521N8223J000 Selection Criteria: This EPCOS - TDK Electronics substitute is appropriate when circuit design permits a tolerance improvement from ±10% to ±5% while maintaining the 630V DC voltage rating. The part maintains identical lead spacing (0.394"), enabling direct PCB footprint compatibility. Physical dimensions are comparable (13.00mm x 5.00mm vs 12.50mm x 5.50mm), with slightly reduced height (11.00mm vs 12.00mm). All regulatory compliance certifications (ROHS3, REACH unaffected) are maintained. This substitute is classified as an upgrade due to superior tolerance specification and higher inventory availability (24398 units).

DME10S22K-F Selection Criteria: This Cornell Dubilier Electronics substitute is appropriate when circuit design requires increased voltage margin beyond the 630V DC specification. The 1000V (1kV) DC rating provides enhanced safety margin in high-voltage applications. The part maintains identical capacitance, tolerance, and operating temperature range. However, physical dimensions increase proportionally (15.50mm x 7.50mm with 17.00mm seated height) and lead spacing expands to 0.492" (12.50mm). PCB layout modifications are required to accommodate the larger footprint and increased lead spacing. All regulatory compliance certifications are maintained. This substitute is selected only when voltage rating upgrade is a design requirement.

Frequently Asked Questions (FAQ)

Q1: Can B32521N8223J000 be used as a direct replacement for DME6S22K-F without PCB modification?

A: Yes, B32521N8223J000 maintains identical lead spacing (0.394" / 10.00mm) and comparable physical dimensions. The footprint is compatible with the original DME6S22K-F PCB layout. The ±5% tolerance provides improved performance within the same 630V DC voltage specification.

Q2: What are the physical constraints when substituting DME10S22K-F for DME6S22K-F?

A: DME10S22K-F requires PCB layout modifications. Lead spacing increases from 0.394" to 0.492", and physical dimensions expand from 12.50mm x 5.50mm to 15.50mm x 7.50mm. Seated height increases from 12.00mm to 17.00mm. These dimensional changes necessitate PCB redesign to accommodate the larger component footprint.

Q3: Are all three parts (DME6S22K-F, B32521N8223J000, DME10S22K-F) suitable for automotive applications?

A: B32521N8223J000 is explicitly rated for automotive applications and EMI/RFI suppression. DME6S22K-F and DME10S22K-F are specified for general-purpose applications. Automotive application suitability must be verified against specific circuit requirements and environmental specifications.

Q4: What is the tolerance difference between the main part and substitutes?

A: DME6S22K-F and DME10S22K-F both specify ±10% tolerance. B32521N8223J000 provides tighter ±5% tolerance, representing a 50% improvement in capacitance accuracy. This tolerance improvement may benefit circuits requiring precise capacitance values.

Q5: Do all substitutes maintain the same operating temperature range?

A: Yes, all three parts (DME6S22K-F, B32521N8223J000, and DME10S22K-F) operate across the identical temperature range of -55°C to 125°C. Operating temperature specifications are equivalent across all substitutes.

Q6: What is the AC voltage rating difference between substitutes?

A: DME6S22K-F and DME10S22K-F both specify 250V AC rating. B32521N8223J000 specifies 200V AC rating. For AC applications, the 250V AC rating of the original part or DME10S22K-F is preferred. B32521N8223J000 is suitable only for AC applications not exceeding 200V.

Q7: Are all parts ROHS3 compliant and REACH unaffected?

A: Yes, all three parts maintain ROHS3 compliance and REACH unaffected status. Regulatory compliance is equivalent across DME6S22K-F, B32521N8223J000, and DME10S22K-F.

Q8: Which substitute offers the best inventory availability?

A: DME10S22K-F has the highest inventory (29292 units), followed by B32521N8223J000 (24398 units). The original DME6S22K-F has 1045 units in stock. Inventory levels should be considered for supply chain planning and lead time requirements.
