Substitute Part Grouping Explanation

Substitute parts for the DPFF12D56J-F are identified based on the following substitution criteria:

Primary Matching Parameters:

• Capacitance value: 5600 pF (exact match required)
• Tolerance: ±5% (exact match acceptable)
• Dielectric type: Polypropylene (PP), Metallized (exact match required)
• Mounting configuration: Through Hole Radial (exact match required)
• Operating temperature range: -55°C ~ 105°C (substitute must support this range)

Voltage Rating Compatibility:

• DC voltage rating of substitute must be equal to or greater than 1200V
• AC voltage rating of substitute must be equal to or greater than 475V
• Higher voltage ratings are acceptable and provide additional design margin

Physical and Regulatory Compatibility:

• Lead spacing must accommodate PCB footprint requirements
• RoHS3 compliance required for regulatory alignment
• Moisture Sensitivity Level (MSL) of 1 (Unlimited) acceptable
• REACH Unaffected status required

The substitute part BFC238350562 meets all primary matching parameters with enhanced voltage ratings (1600V DC, 550V AC), making it suitable for applications requiring higher voltage margin or operating in more demanding electrical environments.

Engineering Selection Recommendations

Primary Part Selection (DPFF12D56J-F): The DPFF12D56J-F remains the preferred choice when the original design specifications call for the exact physical dimensions, lead spacing of 18.30mm, and the specific DPFF series characteristics. This part is in active production with adequate inventory (892 pieces) and carries full ROHS3 compliance and REACH Unaffected status.

Substitute Part Selection (BFC238350562): The BFC238350562 from Vishay Beyschlag/Draloric/BC Components is electrically compatible as a substitute when the following conditions are met:

1. The PCB footprint can accommodate the different lead spacing of 15.00mm instead of 18.30mm
2. The physical envelope of 17.50mm x 6.00mm and height of 12.00mm fits within the available board space
3. The higher voltage ratings (1600V DC, 550V AC) are acceptable for the application
4. The MMKP383 series characteristics are compatible with the circuit design

Both parts maintain identical electrical performance at the specified 5600 pF capacitance, ±5% tolerance, and -55°C to 105°C operating temperature range. Both are ROHS3 compliant and REACH Unaffected, meeting current regulatory requirements.

Selection Criteria:

• Use DPFF12D56J-F if PCB layout requires the 18.30mm lead spacing and larger physical form factor
• Use BFC238350562 if space constraints favor the compact 15.00mm lead spacing and smaller dimensions, and if the higher voltage ratings provide beneficial design margin

Frequently Asked Questions (FAQ)

Q1: Can BFC238350562 be used as a direct replacement for DPFF12D56J-F in existing designs?

A: Electrical substitution is valid because both parts share identical capacitance (5600 pF), tolerance (±5%), dielectric material (polypropylene metallized), and operating temperature range (-55°C to 105°C). However, physical substitution requires PCB layout verification. The lead spacing differs (18.30mm vs. 15.00mm), and the substitute is physically smaller. The PCB footprint must be checked to confirm compatibility before implementation.

Q2: What are the advantages of using BFC238350562 over DPFF12D56J-F?

A: The BFC238350562 offers higher voltage ratings (1600V DC vs. 1200V DC; 550V AC vs. 475V AC), providing additional electrical margin in high-voltage applications. The compact physical dimensions (17.50mm x 6.00mm vs. 33.00mm x 14.00mm) and lower profile (12.00mm vs. 14.00mm) allow for space-constrained PCB designs. Both parts maintain identical capacitance and tolerance specifications.

Q3: Are there any performance differences between these two parts?

A: Both parts use polypropylene metallized dielectric and operate across the same temperature range (-55°C to 105°C). Performance differences are limited to voltage rating specifications. The BFC238350562 has higher voltage ratings, which may result in lower capacitance drift and improved reliability in high-voltage pulse applications. Both parts are rated for high-pulse and DV/DT applications.

Q4: What is the significance of the different lead spacing?

A: Lead spacing (18.30mm for DPFF12D56J-F vs. 15.00mm for BFC238350562) determines the PCB footprint hole pattern. Substitution requires that the PCB layout accommodate the different spacing. If the original design uses a 18.30mm footprint, the 15.00mm lead spacing of the substitute will not fit without PCB modification. Conversely, if space allows, the tighter 15.00mm spacing may be advantageous.

Q5: Do both parts meet current regulatory requirements?

A: Yes. Both DPFF12D56J-F and BFC238350562 are ROHS3 compliant and REACH Unaffected, meeting current environmental and regulatory standards. Both carry Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no special moisture handling requirements during storage or assembly.

Q6: Which part should be selected for new designs?

A: For new designs, either part is acceptable based on application requirements. If space is not constrained and the original 18.30mm lead spacing is preferred, use DPFF12D56J-F. If compact form factor and higher voltage margin are beneficial, use BFC238350562. Both parts are in active production with adequate inventory availability.

Q7: Are there any temperature or environmental performance differences?

A: Both parts operate identically across the -55°C to 105°C temperature range. No performance differentiation exists for environmental or thermal characteristics. Both maintain the same dielectric material (polypropylene metallized) and are suitable for identical application environments.
