Key Parameters

Substitute Part Grouping Explanation

Substitution of the DPPM20S1K is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 10000 pF (exact match required)
• Tolerance: ±10% (exact match required)
• Voltage Rating - DC: 2000V (minimum requirement; higher ratings acceptable)
• Voltage Rating - AC: 500V (minimum requirement; higher ratings acceptable)
• Dielectric Material: Polypropylene (PP), Metallized (exact match required)

Mechanical Parameters:

• Mounting Type: Through Hole (exact match required)
• Package Type: Radial (exact match required)
• Physical Dimensions: 1.220" L × 0.551" W / 31.00mm × 14.00mm (exact match required)
• Lead Spacing: 1.043" (26.50mm) (exact match required)
• Termination: PC Pins (exact match required)

Environmental Parameters:

• Operating Temperature Range: -40°C to 105°C (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

Substitute parts must satisfy all electrical, mechanical, and environmental parameters listed above to ensure functional and physical compatibility within the original application circuit.

Engineering Selection Recommendations

DPPM20S1K-F as Direct Substitute:

The DPPM20S1K-F is a direct electrical and mechanical equivalent to the DPPM20S1K. Both parts are manufactured by Cornell Dubilier Electronics within the DPPM series and share identical specifications across all critical parameters: capacitance (10000 pF), tolerance (±10%), voltage ratings (2000V DC / 500V AC), dielectric composition (polypropylene metallized), physical dimensions, lead spacing, and operating temperature range.

Key Differentiation:

The primary distinction between the main part and substitute is product status and regulatory compliance. The DPPM20S1K is classified as obsolete, while the DPPM20S1K-F maintains active production status. Additionally, the DPPM20S1K-F achieves ROHS3 compliance, whereas the original part is RoHS non-compliant. Both parts maintain identical REACH and ECCN classifications (REACH Unaffected, EAR99).

Selection Basis:

For new designs or system refreshes, the DPPM20S1K-F is the appropriate selection due to its active product status and improved regulatory compliance. For legacy system maintenance where original specifications must be preserved, the DPPM20S1K-F provides functional and physical compatibility while offering enhanced compliance posture.

Frequently Asked Questions (FAQ)

Q: Can DPPM20S1K-F replace DPPM20S1K in existing circuits?
