Key Parameters

Substitute Part Grouping Explanation

Substitution logic for the DPFF12D33J-F is based on the following criteria:

Mandatory Matching Parameters:

• Capacitance value: 3300 pF (exact match required)
• Tolerance: ±5% (electrical specification match)
• Dielectric material: Polypropylene (PP), Metallized (performance equivalence)
• Mounting type: Through Hole (assembly compatibility)
• Package type: Radial (form factor compatibility)
• Lead spacing: 0.720" (18.30mm) (PCB compatibility)

Allowable Variation Parameters:

• Voltage rating - DC: Equal to or greater than 1200V (1.2kV) (higher ratings provide additional safety margin)
• Voltage rating - AC: Equal to or greater than 475V (higher ratings provide additional safety margin)
• Operating temperature range: Must encompass or exceed -55°C ~ 105°C (wider ranges acceptable)
• Physical dimensions: Variations acceptable if lead spacing remains 0.720" (18.30mm)

Compliance Requirements:

• RoHS3 Compliant status maintained
• REACH Unaffected status maintained
• Active product status preferred

The substitute part 715P332516LD3 meets all mandatory matching parameters and exceeds voltage rating specifications, making it electrically and mechanically compatible with the DPFF12D33J-F.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The DPFF12D33J-F remains the preferred choice when the specified operating temperature range of -55°C ~ 105°C is required. This part provides the exact electrical and mechanical specifications for applications requiring maximum temperature performance.

Substitute Selection Criteria:

The 715P332516LD3 (Orange Drop® 715P series) is electrically compatible and mechanically compatible for applications where the operating temperature range does not exceed -55°C ~ 85°C. The substitute part provides higher voltage ratings (1600V DC / 500V AC), which offers additional safety margin in high-voltage applications. Both parts maintain identical RoHS3 compliance and REACH Unaffected status.

Physical Dimension Consideration:

The substitute part has different physical dimensions (0.402" Dia x 1.252" L versus 1.299" L x 0.500" W). While lead spacing remains identical at 0.720" (18.30mm), board layout space requirements differ. Verify available PCB mounting area before substitution.

Compliance Status:

Both parts are Active products from Cornell Dubilier Electronics, ROHS3 Compliant, and REACH Unaffected. No regulatory barriers exist for either selection.

Frequently Asked Questions (FAQ)

Q: Can the 715P332516LD3 be used as a direct replacement for the DPFF12D33J-F?

A: The 715P332516LD3 is electrically and mechanically compatible for applications operating within -55°C ~ 85°C. The substitute has identical capacitance (3300 pF), tolerance (±5%), dielectric material (PP metallized), mounting type (through hole radial), and lead spacing (0.720"). However, physical dimensions differ, requiring verification of available PCB mounting space. If your application requires operation above 85°C, the DPFF12D33J-F is required.

Q: What are the key differences between these two parts?

A: The primary differences are: (1) Operating temperature range: DPFF12D33J-F operates to 105°C while 715P332516LD3 operates to 85°C; (2) Voltage ratings: 715P332516LD3 has higher ratings (1600V DC / 500V AC versus 1200V DC / 475V AC); (3) Physical dimensions: Different form factors with identical lead spacing; (4) Series designation: DPFF versus Orange Drop® 715P.

Q: Are both parts RoHS compliant?

A: Yes. Both the DPFF12D33J-F and 715P332516LD3 are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements.

Q: Does the higher voltage rating of the substitute part affect circuit performance?

A: No. Higher voltage ratings do not negatively affect circuit performance. The 715P332516LD3 with 1600V DC / 500V AC ratings provides additional safety margin and is suitable for applications rated at or below 1200V DC / 475V AC.

Q: Will the different physical dimensions cause PCB assembly issues?

A: Lead spacing remains identical at 0.720" (18.30mm), ensuring PCB hole pattern compatibility. However, the substitute part has a different form factor (0.402" Dia x 1.252" L versus 1.299" L x 0.500" W). Verify available mounting area on your PCB before substitution to ensure clearance from adjacent components.

Q: Which part should I select for new designs?

A: For new designs, select based on operating temperature requirements. If operation above 85°C is required, use DPFF12D33J-F. If maximum operating temperature is 85°C or below, either part is acceptable. The 715P332516LD3 offers higher voltage ratings and greater inventory availability (2101 pcs versus 848 pcs).

Q: Are there any application-specific considerations?

A: Both parts are rated for high pulse and DV/DT applications. The 715P332516LD3 is additionally rated for audio and high frequency/switching applications. Verify that your specific application requirements align with the selected part's rated applications.
