Substitute Part Grouping Explanation

Substitution of the DPPM16D22K is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must maintain:

• Identical capacitance value: 2200 pF
• Identical tolerance: ±10%
• Identical DC voltage rating: 1600V (1.6kV)
• Identical AC voltage rating: 500V
• Identical dielectric material: Polypropylene (PP), Metallized
• Identical operating temperature range: -40°C ~ 105°C
• Identical mounting type: Through Hole
• Identical package configuration: Radial
• Identical physical dimensions: 0.984" L x 0.315" W (25.00mm x 8.00mm)
• Identical maximum seated height: 0.650" (16.50mm)
• Identical lead spacing: 0.827" (21.00mm)
• Identical termination type: PC Pins

The DPPM16D22K-F qualifies as a direct substitute based on complete parameter alignment across all specified criteria.

Parameter Comparison

Engineering Selection Recommendations

The DPPM16D22K-F is the direct equivalent substitute for the obsolete DPPM16D22K. Both components are manufactured by Cornell Dubilier Electronics within the DPPM series and share identical electrical and mechanical specifications. The primary distinction is product status: the DPPM16D22K is obsolete, while the DPPM16D22K-F is active and currently in production.

An additional compliance advantage exists with the DPPM16D22K-F: it carries ROHS3 compliance certification, whereas the original DPPM16D22K is RoHS non-compliant. Both parts maintain REACH Unaffected status. For new designs or systems requiring regulatory compliance with modern environmental standards, the DPPM16D22K-F is the appropriate selection. For legacy system maintenance where RoHS compliance is not a requirement, the DPPM16D22K-F remains functionally equivalent and provides the advantage of active product availability.

Frequently Asked Questions (FAQ)

Q: Can the DPPM16D22K-F be used as a direct replacement for the DPPM16D22K in existing assemblies?

A: Yes. The DPPM16D22K-F is electrically and mechanically identical to the DPPM16D22K. All critical parameters—capacitance, voltage ratings, dielectric material, operating temperature range, physical dimensions, lead spacing, and termination type—are identical. Direct substitution is valid for through-hole PCB applications.

Q: What is the primary reason for substituting the DPPM16D22K?

A: The DPPM16D22K is classified as obsolete. The DPPM16D22K-F is the active equivalent from the same manufacturer and series, ensuring continued component availability for procurement and system support.

Q: Are there any differences in packaging between these parts?

A: The main part (DPPM16D22K) is specified with standard packaging, while the substitute (DPPM16D22K-F) is supplied in bulk packaging. Both maintain identical component specifications and radial case configuration. Packaging format does not affect electrical or mechanical performance.

Q: Does the DPPM16D22K-F meet modern environmental compliance standards?

A: The DPPM16D22K-F carries ROHS3 compliance certification. The original DPPM16D22K is RoHS non-compliant. Both maintain REACH Unaffected status. For applications requiring RoHS compliance, the DPPM16D22K-F is the appropriate selection.

Q: Are the physical dimensions identical between the two parts?

A: Yes. Both the DPPM16D22K and DPPM16D22K-F share identical dimensions: 0.984" L x 0.315" W (25.00mm x 8.00mm), with a maximum seated height of 0.650" (16.50mm) and lead spacing of 0.827" (21.00mm). PCB layout and mechanical clearance requirements are identical.

Q: What applications are these capacitors suitable for?

A: Both parts are specified for high-frequency switching applications, high-pulse environments with high DV/DT characteristics, and snubber circuits. The 1.6 kV DC and 500V AC voltage ratings support demanding power conversion and switching applications.
