DPM6W1K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPM6W1K-F is a 1 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DPM series. This radial through-hole component operates at 630V DC with polypropylene metallized dielectric construction. The part is classified as Active product status with 1094 units currently in stock. Film capacitors of this specification are essential in DC link filtering, DC filtering applications, and high-frequency switching circuits where low ESR and low ESL characteristics are required. Identifying equivalent substitute parts ensures design flexibility and supply chain continuity when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DPM6W1K-F are identified based on strict electrical and mechanical parameter matching. The substitution logic is based on the following criteria:

Electrical Parameters (Non-negotiable):

• Capacitance value: 1 µF (exact match required)
• DC voltage rating: 630V minimum (equal or higher acceptable)
• Tolerance: ±10% (equal or tighter acceptable)
• Dielectric type: Polypropylene metallized (must match)
• Temperature range: -55°C to 105°C (must match or exceed)

Mechanical Parameters (Design-dependent):

• Mounting type: Through hole radial (must match)
• Termination style: PC pins (must match)
• Package case: Radial (must match)

Compliance Parameters:

• RoHS3 compliance required
• REACH unaffected status required

The 105PPB630K qualifies as a substitute based on matching all critical electrical parameters and maintaining identical operating temperature range, mounting configuration, and regulatory compliance status.

Engineering Selection Recommendations

Primary Part: DPM6W1K-F

The DPM6W1K-F remains the preferred selection when available. This part carries Active product status with established supply (1094 units in stock) and is fully compliant with ROHS3 and REACH requirements. The component is suitable for DC link and DC filtering applications requiring low ESR and low ESL performance.

Substitute Part: 105PPB630K

The 105PPB630K qualifies as a direct electrical and mechanical substitute. Both parts share identical capacitance (1 µF), DC voltage rating (630V), tolerance (±10%), dielectric composition (polypropylene metallized), operating temperature range (-55°C to 105°C), mounting configuration (through-hole radial), and termination style (PC pins). Both components maintain identical maximum seated height (30.00mm) and comply with ROHS3 and REACH standards.

The 105PPB630K is available in higher inventory (1998 units) and carries Active product status. The substitute part is rated for higher AC voltage (400V versus 250V), which provides additional design margin in AC applications. Lead spacing differs slightly (37.50mm versus 40.00mm) and physical dimensions vary marginally, requiring PCB layout verification before implementation.

Both parts are suitable for commutation, high pulse DV/DT, and snubber applications where the electrical parameters align with circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the 105PPB630K replace the DPM6W1K-F in all applications?

A: The 105PPB630K is electrically and mechanically compatible based on matching capacitance, voltage rating, tolerance, dielectric type, temperature range, mounting type, and termination style. However, PCB layout verification is required due to differences in lead spacing (37.50mm versus 40.00mm) and physical dimensions (42.50mm x 22.00mm versus 47.00mm x 19.00mm).

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Series designation (DPM versus PPB), (2) AC voltage rating (250V versus 400V), (3) Lead spacing (40.00mm versus 37.50mm), (4) Physical length (47.00mm versus 42.50mm), and (5) Physical width (19.00mm versus 22.00mm). All critical electrical parameters and operating conditions are identical.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the DPM6W1K-F and 105PPB630K are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the significance of the higher AC voltage rating on the substitute part?

A: The 105PPB630K is rated for 400V AC compared to the DPM6W1K-F at 250V AC. This higher rating provides additional design margin in circuits with AC voltage stress. However, the DC voltage rating (630V) is identical for both parts, which is the primary specification for DC link and DC filtering applications.

Q: Can I use these parts interchangeably on the same PCB without modification?

A: Direct PCB interchangeability requires verification. Lead spacing differs by 2.50mm (40.00mm versus 37.50mm), and physical dimensions vary. PCB hole pattern and component placement must be confirmed compatible before substitution. Physical dimensions must be verified against available PCB space.

Q: What applications are these capacitors designed for?

A: The DPM6W1K-F is specified for DC link, DC filtering, high-frequency, and switching applications. The 105PPB630K is specified for commutation, high pulse DV/DT, and snubber applications. Both parts utilize low ESR and low ESL characteristics suitable for their respective application categories.

Q: How do I verify compatibility before ordering the substitute part?

A: Confirm the following: (1) Capacitance requirement is 1 µF, (2) DC voltage requirement is 630V or lower, (3) AC voltage requirement does not exceed 400V, (4) Operating temperature range is within -55°C to 105°C, (5) PCB layout accommodates lead spacing of 37.50mm and physical dimensions of 42.50mm x 22.00mm, (6) Through-hole radial mounting with PC pins is compatible with your assembly process.
