Key Parameters

Substitute Part Grouping Explanation

Substitution of the DPPM12S33K-F is permissible when the alternative part maintains the following critical parameters:

Mandatory Matching Parameters:

• Capacitance value: 0.033 µF (exact match required)
• Dielectric material: Polypropylene (PP), Metallized
• Mounting type: Through Hole
• Package type: Radial
• Termination: PC Pins

Allowable Parameter Variations:

• Voltage Rating - DC: Equal to or greater than 1200V
• Voltage Rating - AC: Equal to or greater than 475V
• Tolerance: Equal to or tighter than ±10%
• Operating Temperature Range: Must encompass or exceed -40°C to 105°C
• Physical dimensions: May vary within PCB layout constraints
• RoHS/REACH compliance: Must maintain or exceed current certification level

The substitute part 715P333516MD3 meets all mandatory matching parameters and exceeds voltage ratings (1600V DC, 500V AC) and tolerance specifications (±5%), qualifying it as a direct electrical substitute with enhanced performance margins.

Parameter Comparison

Engineering Selection Recommendations

Primary Part: DPPM12S33K-F

Use the DPPM12S33K-F when:

• Original design specifications require the DPPM series characteristics
• Operating temperature must reach 105°C
• Exact tolerance of ±10% is acceptable for the application
• Physical dimensions of 31.00mm x 14.00mm fit the PCB layout
• Supply availability is confirmed at 1099 units in stock

Substitute Part: 715P333516MD3

Use the 715P333516MD3 when:

• DPPM12S33K-F supply is unavailable or lead times exceed project requirements
• Application can operate within the -55°C to 85°C temperature range
• Enhanced voltage margins (1600V DC, 500V AC) provide design safety
• Tighter tolerance (±5%) improves circuit performance
• Physical dimensions of 20.60mm diameter x 41.90mm length accommodate PCB layout
• Orange Drop® 715P series performance characteristics are acceptable
• Both parts maintain ROHS3 compliance and REACH Unaffected status

Critical Consideration:

The operating temperature range differs between parts. The DPPM12S33K-F operates to 105°C, while the 715P333516MD3 operates to 85°C maximum. Substitution is valid only if the application's maximum operating temperature does not exceed 85°C.

Frequently Asked Questions (FAQ)

Q: Can the 715P333516MD3 directly replace the DPPM12S33K-F in all applications?

A: Direct replacement is valid when the application's maximum operating temperature does not exceed 85°C. The DPPM12S33K-F is rated to 105°C, while the 715P333516MD3 is rated to 85°C maximum. All other electrical parameters (capacitance, voltage ratings, tolerance, dielectric material) are compatible or superior in the substitute part.

Q: What is the impact of the ±5% tolerance in the 715P333516MD3 compared to the ±10% tolerance in the DPPM12S33K-F?

A: The ±5% tolerance in the 715P333516MD3 is tighter than the ±10% tolerance in the DPPM12S33K-F. This means the substitute part will have capacitance values closer to the nominal 0.033 µF specification, which may improve circuit performance and stability in applications sensitive to capacitance variation.

Q: Are there physical dimension constraints when substituting the 715P333516MD3 for the DPPM12S33K-F?

A: Yes. The DPPM12S33K-F measures 31.00mm x 14.00mm with a height of 23.50mm and lead spacing of 26.50mm. The 715P333516MD3 measures 20.60mm diameter x 41.90mm length with a height of 28.00mm and lead spacing of 27.80mm. PCB layout must accommodate the larger axial dimension (41.90mm vs. 31.00mm) and slightly increased lead spacing (27.80mm vs. 26.50mm).

Q: Do both parts meet the same compliance standards?

A: Yes. Both the DPPM12S33K-F and 715P333516MD3 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

Q: What voltage margin does the 715P333516MD3 provide over the DPPM12S33K-F?

A: The 715P333516MD3 provides a 400V DC margin (1600V vs. 1200V) and a 25V AC margin (500V vs. 475V). These enhanced voltage ratings provide additional design safety and stress reduction on the component during operation.

Q: Can the DPPM12S33K-F be used as a substitute for the 715P333516MD3?

A: No. The DPPM12S33K-F has lower voltage ratings (1200V DC vs. 1600V DC) and a wider tolerance (±10% vs. ±5%), making it unsuitable as a substitute for applications designed around the 715P333516MD3 specifications.

Q: What is the inventory status for both parts?

A: The DPPM12S33K-F has 1099 units in stock. The 715P333516MD3 has 1860 units in stock. Both parts are listed as Active in product status.
