Substitute Part Grouping Explanation

Substitution eligibility for the DPP4P15K-F is determined by the following criteria:

Mandatory Matching Parameters:

Capacitance value: 0.15 µF (exact match required)
Dielectric material: Polypropylene (PP), Metallized
Mounting type: Through Hole, Radial
Lead spacing: 1.083" (27.50mm)

Engineering Selection Recommendations

Primary Selection - DPP4P15K-F: Select the DPP4P15K-F when the original specification is available and component stock is sufficient. This part maintains exact dimensional and electrical specifications as originally designed. Product status is Active with 767 units in current inventory.

Substitute Selection - 154PPB630K: The 154PPB630K is a valid substitute when DPP4P15K-F availability is constrained. This part provides identical electrical performance for the 0.15 µF, ±10% capacitance requirement and maintains full compatibility with the 27.50mm lead spacing PCB footprint. The elevated DC voltage rating (630V versus 400V) provides additional design margin without affecting circuit operation. Physical dimensions show a reduced height profile (20.00mm versus 26.00mm seated height), which may provide PCB layout advantages. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating. Product status is Active with 643 units in current inventory.

Compliance Verification: Both parts satisfy ROHS3 compliance, REACH unaffected status, and EAR99 export classification requirements.

Frequently Asked Questions (FAQ)

Q: Can 154PPB630K be used as a direct replacement for DPP4P15K-F in existing designs?

A: Yes. The 154PPB630K maintains identical capacitance (0.15 µF), tolerance (±10%), lead spacing (27.50mm), dielectric material (metallized polypropylene), operating temperature range (-55°C ~ 105°C), and termination type (PC Pins). The higher voltage rating (630V DC versus 400V DC) does not create compatibility issues and provides additional voltage margin. The reduced height (20.00mm versus 26.00mm) is compatible with standard PCB clearance requirements.

Q: Are there any physical dimension concerns when substituting 154PPB630K for DPP4P15K-F?

A: Physical dimensions differ slightly. The 154PPB630K is 0.039" (1.00mm) narrower in width and 0.237" (6.00mm) shorter in seated height compared to the DPP4P15K-F. These variations remain within typical PCB design tolerances for radial through-hole components. Verify clearance in your specific PCB layout if space constraints exist.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both DPP4P15K-F and 154PPB630K are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export purposes. Both carry unlimited moisture sensitivity level (MSL 1) rating.

Q: What is the lead spacing for both parts?

A: Both parts have identical lead spacing of 1.083" (27.50mm), ensuring PCB footprint compatibility without modification.

Q: Can the substitute part handle the same applications as the original?

A: Yes. Both parts are rated for high-frequency and switching applications. The 154PPB630K additionally supports commutation, high pulse DV/DT, and snubber applications due to its elevated voltage rating, making it suitable for a broader range of circuit designs.

Q: What is the current inventory status for both parts?

A: DPP4P15K-F has 767 units in stock. 154PPB630K has 643 units in stock. Both are listed as Active products.
