Key Parameters

Substitute Part Grouping Explanation

Substitution for the DPPM12D33K is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 3300 pF
• Tolerance: ±10%
• Voltage rating - DC: 1200V (1.2kV) minimum
• Voltage rating - AC: 475V minimum
• Dielectric material: Polypropylene (PP), Metallized

Mechanical Equivalence Criteria:

• Mounting type: Through Hole
• Package type: Radial
• Lead spacing: 0.827" (21.00mm)
• Termination: PC Pins
• Physical dimensions compatible with original footprint

Compliance Considerations:

• RoHS status and REACH compliance affect suitability for regulated applications
• Product status (Active vs. Obsolete) determines long-term availability

Substitute parts must match all electrical parameters and mechanical dimensions. Deviations in any parameter disqualify a part from direct substitution.

Engineering Selection Recommendations

DPPM12D33K-F (Primary Substitute):

The DPPM12D33K-F is a direct electrical and mechanical equivalent to the DPPM12D33K. Both parts share identical capacitance (3300 pF), tolerance (±10%), voltage ratings (1200V DC / 475V AC), dielectric material (polypropylene metallized), and physical dimensions (lead spacing 0.827", radial package, through-hole mounting).

The DPPM12D33K-F differs in product status and compliance:

• Product Status: Active (versus Obsolete for DPPM12D33K)
• RoHS Status: ROHS3 Compliant (versus RoHS non-compliant for DPPM12D33K)

For applications subject to RoHS3 regulations or requiring long-term component availability, the DPPM12D33K-F is the appropriate selection. Both parts are functionally interchangeable in circuit applications.

715P332516LD3 (Secondary Substitute):

The part number 715P332516LD3 is listed as a substitute in the provided input data. Complete electrical and mechanical specifications for this part are not provided in the input parameters. Direct substitution assessment cannot be completed without full parameter data.

Frequently Asked Questions (FAQ)

Q: Can DPPM12D33K-F replace DPPM12D33K in existing designs?

A: Yes. The DPPM12D33K-F is electrically and mechanically equivalent. Both parts have identical capacitance (3300 pF), tolerance (±10%), voltage ratings (1200V DC / 475V AC), dielectric material (polypropylene metallized), operating temperature range (-40°C ~ 105°C), and physical dimensions (lead spacing 0.827", radial through-hole package). Direct substitution is valid.

Q: What is the difference between DPPM12D33K and DPPM12D33K-F?

A: The primary differences are product status and compliance certification. DPPM12D33K is obsolete and RoHS non-compliant. DPPM12D33K-F is active and ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Why is the DPPM12D33K classified as obsolete?

A: Product status is determined by the manufacturer. The DPPM12D33K is no longer in active production. The DPPM12D33K-F serves as the active production equivalent.

Q: Are there any physical dimension differences between these parts?

A: No. Both DPPM12D33K and DPPM12D33K-F have identical dimensions: 0.984" L x 0.295" W (25.00mm x 7.50mm), height 0.571" (14.50mm), and lead spacing 0.827" (21.00mm). PCB footprints are identical.

Q: What applications are these capacitors suitable for?

A: Both parts are rated for high-frequency switching, high-pulse DV/DT applications, and snubber circuits. Operating temperature range is -40°C ~ 105°C.

Q: Is RoHS3 compliance required for my application?

A: RoHS3 compliance is mandatory for products sold in the European Union and many regulated markets. If your application is subject to RoHS3 regulations, DPPM12D33K-F is the required selection. DPPM12D33K is RoHS non-compliant and unsuitable for regulated applications.

Q: What is the lead spacing specification?

A: Lead spacing for both parts is 0.827" (21.00mm). This dimension determines PCB hole pattern compatibility and must match your circuit board design.
