DMM6S1K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DMM6S1K-F is a 10000 pF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DMM series. This radial through-hole component operates at 630V DC with ±10% capacitance tolerance and polyester metallized dielectric construction. The part is Active in product status with 1064 units in current inventory stock. Film capacitors of this specification are essential in general-purpose applications requiring stable capacitance, low ESR, and high voltage performance across industrial and commercial equipment. Equivalent and substitute parts are identified when design flexibility, inventory availability, or manufacturing sourcing requires alternative component selection while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DMM6S1K-F are classified based on electrical parameter equivalence and mechanical compatibility. The substitution logic is strictly defined by the following criteria:

Direct Equivalents maintain identical electrical specifications: 10000 pF capacitance, ±10% tolerance, 630V DC rating, 250V AC rating, polyester metallized dielectric, -55°C to 125°C operating range, through-hole radial mounting, 10.00mm lead spacing, and PC pin termination. These parts are interchangeable without circuit redesign.

Upgraded Substitutes provide enhanced performance through tighter tolerance (±5% versus ±10%) or improved dielectric material specifications while maintaining the same capacitance value, voltage ratings, operating temperature range, mounting type, lead spacing, and termination. These parts are suitable for applications requiring higher precision.

Similar Substitutes match all critical electrical parameters (capacitance, voltage ratings, tolerance, dielectric type, operating temperature) and mechanical requirements (through-hole radial, lead spacing, termination) but may have minor dimensional variations or different temperature operating ranges within acceptable limits. These parts are compatible for general-purpose applications.

All substitute parts listed maintain ROHS3 compliance, REACH unaffected status, and EAR99 export classification consistent with the main part.

Parameter Comparison

Engineering Selection Recommendations

DME6S1K-F (Direct Equivalent): This Cornell Dubilier Electronics part is a direct electrical and mechanical equivalent to the DMM6S1K-F. Both components share identical capacitance, voltage ratings, tolerance, dielectric material, operating temperature range, and lead spacing. The DME6S1K-F is suitable for one-to-one replacement in existing designs. Higher inventory availability (3603 units) supports supply chain continuity. Both parts maintain Active product status and ROHS3 compliance.

B32521N8103J000 (Upgraded Substitute): This EPCOS-TDK Electronics component provides tighter capacitance tolerance (±5% versus ±10%), which enhances circuit precision in applications sensitive to capacitance variation. The part maintains 630V DC and 200V AC ratings, polyester metallized dielectric construction, -55°C to 125°C operating range, and identical lead spacing. The AC voltage rating is 50V lower than the main part; this substitution is appropriate only when AC voltage stress does not exceed 200V. The stacked dielectric construction and automotive application rating indicate suitability for demanding environments. ROHS3 compliance and Active status are maintained.

QXK2J103KTP (Similar Substitute): This Nichicon component matches all critical electrical parameters: 10000 pF capacitance, ±10% tolerance, 630V DC and 250V AC ratings, polyester metallized dielectric, and identical lead spacing. The operating temperature range is -40°C to 105°C, which is narrower than the main part's -55°C to 125°C specification. This substitution is appropriate for applications operating within the -40°C to 105°C window. ROHS3 compliance and Active product status are maintained. Inventory availability (1349 units) supports component sourcing.

All substitute parts are Active in product status, ROHS3 compliant, and suitable for direct PCB integration without mechanical modification.

Frequently Asked Questions (FAQ)

Q: Can DME6S1K-F replace DMM6S1K-F in any application?

A: Yes. The DME6S1K-F is a direct electrical and mechanical equivalent. Both parts have identical capacitance (10000 pF), voltage ratings (630V DC, 250V AC), tolerance (±10%), dielectric material (polyester metallized), operating temperature range (-55°C to 125°C), and lead spacing (10.00mm). No circuit redesign or PCB modification is required.

Q: What is the key difference between B32521N8103J000 and DMM6S1K-F?

A: The B32521N8103J000 provides tighter capacitance tolerance (±5% versus ±10%), which improves circuit precision. However, its AC voltage rating is 200V compared to the main part's 250V AC. This substitution is suitable only when AC voltage stress remains below 200V. All other electrical and mechanical parameters are compatible.

Q: Is QXK2J103KTP suitable for low-temperature applications below -40°C?

A: No. The QXK2J103KTP operating temperature range is -40°C to 105°C. For applications requiring operation below -40°C, the DMM6S1K-F or DME6S1K-F (-55°C to 125°C range) must be used.

Q: Do all substitute parts fit the same PCB footprint as DMM6S1K-F?

A: Yes. All substitute parts maintain the same lead spacing (0.394" / 10.00mm), through-hole radial mounting type, and PC pin termination. Physical dimensions vary slightly, but PCB footprint compatibility is maintained. Verify component height clearance in confined spaces: DMM6S1K-F height is 0.394" (10.00mm), DME6S1K-F is 0.374" (9.50mm), B32521N8103J000 is 0.354" (9.00mm), and QXK2J103KTP is 0.413" (10.50mm).

Q: Are all substitute parts RoHS compliant?

A: Yes. All listed substitute parts (DME6S1K-F, B32521N8103J000, QXK2J103KTP) are ROHS3 compliant, matching the main part's environmental compliance status.

Q: Which substitute part has the highest inventory availability?

A: The DME6S1K-F has the highest current inventory with 3603 units in stock, followed by B32521N8103J000 with 3449 units. The main part DMM6S1K-F has 1064 units, and QXK2J103KTP has 1349 units.

Q: Can B32521N8103J000 be used in automotive applications?

A: Yes. The B32521N8103J000 is rated for automotive applications and EMI/RFI suppression. The main part DMM6S1K-F and other substitutes are rated for general-purpose applications. If automotive qualification is required, B32521N8103J000 is the appropriate selection.
