DPP2P1K-F Film Capacitor Equivalent & Substitute Parts

Part Overview

The DPP2P1K-F is a 0.1 µF film capacitor manufactured by Cornell Dubilier Electronics (CDE) in the DPP series. This radial polypropylene metallized film capacitor is rated for 250V DC operation and features low ESR characteristics suitable for high-frequency and switching applications. The part is currently active in production with 1071 units in stock. Substitute parts are identified when equivalent capacitance, tolerance, and voltage ratings are available from alternative manufacturers, enabling procurement flexibility and supply chain continuity.

Key Parameters

Parameter	Value	Significance for Substitution
Capacitance	0.1 µF	Must match exactly
Tolerance	±10%	Must match or be tighter
Voltage Rating - DC	250V	Substitute must meet or exceed
Dielectric Material	Polypropylene (PP), Metallized	Must match for electrical characteristics
Mounting Type	Through Hole Radial	Must match for PCB compatibility
Operating Temperature Range	-55°C ~ 105°C	Substitute must cover or exceed
RoHS Status	ROHS3 Compliant	Must maintain compliance

Substitute Part Grouping Explanation

Substitution eligibility for the DPP2P1K-F is determined by the following criteria:

Mandatory Matching Parameters:

Capacitance value: 0.1 µF (exact match required)
Tolerance: ±10% (substitute tolerance must be equal or tighter)
Dielectric type: Polypropylene (PP), Metallized (electrical performance requirement)
Mounting configuration: Through Hole Radial (PCB layout requirement)

Minimum Performance Requirements:

Voltage Rating - DC: Substitute must be rated ≥250V DC
Operating Temperature Range: Substitute must support -55°C ~ 105°C or equivalent
RoHS Compliance: ROHS3 Compliant status must be maintained

Acceptable Variations:

Physical dimensions may differ within PCB layout constraints
Lead spacing may vary if through-hole mounting is preserved
Voltage rating may exceed 250V DC (derating provides additional margin)
Packaging format (bulk vs. standard) does not affect electrical equivalence

The identified substitute QXP2G104KRPT from Nichicon meets all mandatory parameters and exceeds minimum voltage requirements at 400V DC.

Engineering Selection Recommendations

Primary Selection: DPP2P1K-F (CDE)

Use the original DPP2P1K-F when:

Operating temperature range must include -55°C minimum
Original design specifications require CDE manufacturer qualification
Supply availability is confirmed (1071 units in stock)

Substitute Selection: QXP2G104KRPT (Nichicon)

The QXP2G104KRPT is electrically and mechanically compatible as a substitute when:

Operating temperature minimum of -40°C is acceptable for the application
Higher voltage rating (400V DC) provides additional safety margin
Nichicon manufacturer qualification is acceptable
Supply continuity from CDE is unavailable
Both parts maintain ROHS3 compliance and REACH unaffected status

Compliance Verification:

Both parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. No additional regulatory review is required for substitution within these parameters.

Frequently Asked Questions (FAQ)

Q: Can QXP2G104KRPT replace DPP2P1K-F in all applications?

A: QXP2G104KRPT is electrically equivalent for applications operating at -40°C or above. If the circuit requires operation below -40°C, the original DPP2P1K-F must be used due to its -55°C minimum operating temperature rating.

Q: Does the higher voltage rating (400V vs 250V) of the substitute create any issues?

A: No. Higher voltage rating provides additional derating margin and does not negatively affect circuit performance. The capacitance and tolerance remain identical.

Q: Are there physical size differences between these parts?

A: Yes. DPP2P1K-F dimensions are 26.00mm L x 10.00mm W with 21.00mm height. QXP2G104KRPT dimensions are 21.00mm L x 7.60mm W with 13.20mm height. Lead spacing differs: 20.00mm vs 17.50mm. PCB layout must accommodate these differences.

Q: Do both parts have the same moisture sensitivity?

A: No. DPP2P1K-F has MSL 1 (Unlimited). QXP2G104KRPT has MSL Not Applicable. This does not affect substitution eligibility.

Q: Are there other substitutes available?

A: The QXP2G104KRPT data indicates secondary substitutes QXT2G104KRPT and QXP2J104KRPT exist within the Nichicon QXP family. These would require separate parameter verification against the DPP2P1K-F specifications.

Q: What is the lead spacing difference impact?

A: DPP2P1K-F has 20.00mm lead spacing; QXP2G104KRPT has 17.50mm. PCB through-hole patterns must be verified for compatibility. If the original PCB is designed for 20.00mm spacing, the substitute cannot be used without PCB modification.
