Key Parameters

Substitute Part Grouping Explanation

Substitution of the DPPM20D47K is determined by strict equivalence across all electrical and mechanical parameters. The substitute part must maintain:

Electrical Parameters:

• Capacitance value: 4700 pF
• Tolerance: ±10%
• Voltage Rating - DC: 2000V (2kV)
• Voltage Rating - AC: 500V
• Dielectric Material: Polypropylene (PP), Metallized
• Operating Temperature Range: -40°C ~ 105°C

Mechanical Parameters:

• Mounting Type: Through Hole
• Package / Case: Radial
• Size / Dimension: 1.220" L x 0.394" W (31.00mm x 10.00mm)
• Height - Seated (Max): 0.807" (20.50mm)
• Lead Spacing: 1.043" (26.50mm)
• Termination: PC Pins

The DPPM20D47K-F meets all substitution criteria as a direct equivalent with identical specifications and active product status.

• Mechanical Equivalence: All mechanical parameters including through-hole mounting, radial package, physical dimensions (31.00mm x 10.00mm), height (20.50mm), lead spacing (26.50mm), and PC pin termination are identical.
• Application Compatibility: Both parts are rated for identical applications: high-frequency switching, high-pulse DV/DT environments, and snubber circuits.

Frequently Asked Questions (FAQ)

Q: Can the DPPM20D47K-F be used as a direct replacement for the DPPM20D47K?

A: Yes. The DPPM20D47K-F is a direct equivalent substitute. All electrical parameters (capacitance, tolerance, voltage ratings, dielectric material, operating temperature) and mechanical parameters (mounting type, package, dimensions, lead spacing, termination) are identical between the two parts.

Q: What is the difference between the DPPM20D47K and DPPM20D47K-F?

A: The primary differences are product status and regulatory compliance. The DPPM20D47K is obsolete and RoHS non-compliant, while the DPPM20D47K-F is an active product that is ROHS3 Compliant. The DPPM20D47K-F also has a defined Moisture Sensitivity Level (MSL) of 1 (Unlimited). All electrical and mechanical specifications are identical.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both the DPPM20D47K and DPPM20D47K-F have identical physical dimensions: 1.220" L x 0.394" W (31.00mm x 10.00mm), with a maximum seated height of 0.807" (20.50mm) and lead spacing of 1.043" (26.50mm). Both use radial through-hole mounting with PC pin termination.

Q: Will the DPPM20D47K-F work in circuits designed for the DPPM20D47K?

A: Yes. The DPPM20D47K-F maintains identical electrical specifications including 4700 pF capacitance, ±10% tolerance, 2000V DC / 500V AC voltage ratings, polypropylene metallized dielectric, and -40°C ~ 105°C operating temperature range. It is suitable for the same applications: high-frequency switching, high-pulse DV/DT, and snubber circuits.

Q: What is the packaging difference between these parts?

A: The DPPM20D47K-F is supplied in Bulk packaging, while the original DPPM20D47K packaging specification is not provided. Both parts are identical in component form and function.

Q: Is the DPPM20D47K-F RoHS compliant?

A: Yes. The DPPM20D47K-F is ROHS3 Compliant. The original DPPM20D47K is RoHS non-compliant. If RoHS compliance is required for your application, the DPPM20D47K-F is the appropriate selection.

Q: What does MSL 1 (Unlimited) mean for the DPPM20D47K-F?

A: Moisture Sensitivity Level 1 (Unlimited) indicates that the component has minimal moisture sensitivity and does not require special moisture control during storage or handling. There are no time-limited storage restrictions.

Q: Are both parts from the same manufacturer?

A: Yes. Both the DPPM20D47K and DPPM20D47K-F are manufactured by Cornell Dubilier Electronics (CDE) and are part of the DPPM series.
