Key Parameters

Substitute Part Grouping Explanation

Substitution of the DPPM20D82K-F is determined by strict equivalence in the following critical parameters:

Primary Substitution Criteria:

• Capacitance value: 8200 pF (exact match required)
• Voltage rating - DC: 2000V minimum (equal or higher acceptable)
• Dielectric material: Polypropylene (PP), Metallized (required for application compatibility)
• Mounting type: Through Hole Radial (physical and electrical interface requirement)
• Termination: PC Pins (connection compatibility)

Secondary Compatibility Parameters:

• Tolerance: ±10% or tighter (±5% is acceptable as superior specification)
• Operating temperature range: Must encompass or exceed -40°C ~ 105°C
• RoHS3 compliance: Required for regulatory alignment
• AC voltage rating: 500V or higher acceptable

The substitute part B32672L8822J000 meets all primary and secondary criteria, with improvements in tolerance (±5% vs ±10%), AC voltage rating (700V vs 500V), and operating temperature range (-55°C ~ 110°C vs -40°C ~ 105°C).

Engineering Selection Recommendations

DPPM20D82K-F (Main Part):

• Select when CDE-specific supply chain or inventory requirements apply
• Active product status with 960 pieces in stock ensures availability
• ROHS3 compliant and REACH unaffected for regulatory requirements
• Suitable for all specified high-frequency switching and snubber applications

B32672L8822J000 (Substitute):

• Select as primary alternative when supply constraints affect DPPM20D82K-F availability
• Superior specifications in tolerance (±5%), AC voltage rating (700V), and operating temperature range (-55°C ~ 110°C) provide design margin
• EPCOS/TDK Electronics manufacturing ensures quality and reliability in industrial applications
• Significantly higher inventory (45,626 pieces) supports rapid procurement
• ROHS3 compliant and REACH unaffected for regulatory requirements
• Smaller physical dimensions (18.00mm L x 6.00mm W vs 31.00mm L x 13.00mm W) may require PCB layout verification

Both parts are active products with full regulatory compliance. Selection between them is based on supply availability, inventory requirements, and physical space constraints on the printed circuit board.

Frequently Asked Questions (FAQ)

Q: Can B32672L8822J000 be used as a direct replacement for DPPM20D82K-F?

A: Yes. Both parts share identical capacitance (8200 pF), DC voltage rating (2000V), dielectric material (polypropylene metallized), mounting type (through hole radial), and termination (PC pins). The substitute meets or exceeds all critical electrical parameters. Physical dimensions differ; verify PCB layout compatibility before implementation.

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

A: The primary differences are: (1) Tolerance: B32672L8822J000 has ±5% versus DPPM20D82K-F at ±10%; (2) AC voltage rating: 700V versus 500V; (3) Operating temperature range: -55°C ~ 110°C versus -40°C ~ 105°C; (4) Physical size: B32672L8822J000 is significantly smaller; (5) Manufacturer: EPCOS/TDK Electronics versus Cornell Dubilier Electronics. All differences favor the substitute part from an electrical specification standpoint.

Q: Are there any physical compatibility concerns?

A: Yes. B32672L8822J000 has smaller dimensions (18.00mm L x 6.00mm W x 12.00mm H) compared to DPPM20D82K-F (31.00mm L x 13.00mm W x 23.00mm H). Lead spacing also differs: 15.00mm versus 26.50mm. Verify PCB footprint and component placement before substitution to ensure mechanical fit and thermal management requirements are met.

Q: Do both parts meet regulatory requirements?

A: Yes. Both DPPM20D82K-F and B32672L8822J000 are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8532.25.0070. They are suitable for applications requiring regulatory compliance in industrial and commercial markets.

Q: Which part should be selected for new designs?

A: Selection depends on supply chain strategy and physical constraints. For new designs with no existing PCB layout, B32672L8822J000 is preferred due to superior electrical specifications (tighter tolerance, higher AC rating, wider temperature range), higher inventory availability (45,626 pieces), and smaller footprint. For existing designs or when CDE-specific requirements apply, DPPM20D82K-F remains the primary choice.

Q: What is the substitution logic for these parts?

A: Substitution is based on strict equivalence in capacitance value (8200 pF), DC voltage rating (2000V), dielectric material (polypropylene metallized), mounting type (through hole radial), and termination (PC pins). Secondary parameters including tolerance, AC voltage rating, and operating temperature range are evaluated for compatibility. B32672L8822J000 meets all primary criteria and exceeds secondary specifications.
