Key Parameters

Substitute Part Grouping Explanation

Substitution of the DPPM16D22K-F is determined by the following critical parameters:

Electrical Compatibility Requirements:

• Capacitance value must remain 2200 pF
• Tolerance must be ±10% or tighter
• Voltage rating (DC) must equal or exceed 1600V
• AC voltage rating must equal or exceed 500V
• Dielectric material must be Polypropylene (PP), Metallized

Mechanical Compatibility Requirements:

• Mounting type must be Through Hole
• Package type must be Radial
• Lead spacing must be 0.827 inches (21.00 mm)
• Termination must be PC Pins

Environmental & Compliance Requirements:

• Operating temperature range must encompass -40°C to 105°C
• RoHS3 compliance required
• MSL rating of 1 (Unlimited) required

The DPPM20D22K-F qualifies as a substitute because it maintains identical capacitance, tolerance, AC voltage rating, dielectric material, mounting configuration, lead spacing, termination type, operating temperature range, and compliance certifications. The DC voltage rating increases from 1600V to 2000V, which represents an upgrade in voltage capability while maintaining all other electrical and mechanical parameters.

Engineering Selection Recommendations

DPPM16D22K-F Selection Criteria: Select the DPPM16D22K-F when the circuit design specifies a maximum DC voltage rating of 1600V and physical space constraints require the smaller package dimensions (0.315" width, 16.50 mm height). This part is Active in product status with 876 units in stock. ROHS3 compliance and unlimited MSL rating support standard manufacturing and storage conditions.

DPPM20D22K-F Selection Criteria: Select the DPPM20D22K-F when the circuit design permits or requires a higher DC voltage rating of 2000V. The increased voltage rating provides additional safety margin in high-pulse and switching applications. Physical dimensions increase slightly (0.354" width, 17.50 mm height), but lead spacing remains identical at 0.827 inches, ensuring PCB footprint compatibility. This part is Active in product status with 4720 units in stock, providing greater availability. ROHS3 compliance and unlimited MSL rating are maintained.

Both parts are suitable for high-frequency switching, high-pulse, DV/DT, and snubber circuit applications. Selection between them depends on voltage requirement and available board space.
