Key Parameters

Substitute Part Grouping Explanation

Substitution of the DPPM20S15K-F is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 0.015 µF (exact match required)
• Voltage rating - DC: 2000V minimum (equal or higher acceptable)
• Voltage rating - AC: 500V minimum (equal or higher acceptable)
• Dielectric material: Polypropylene (PP), Metallized (exact match required)

Mechanical Compatibility Requirements:

• Mounting type: Through Hole (exact match required)
• Package / Case: Radial (exact match required)
• Termination: PC Pins (exact match required)

Compliance Requirements:

• RoHS3 Compliant status (required for regulated applications)
• REACH Unaffected status (required for regulated applications)

The substitute part R73UR2150SE00J from KEMET meets all electrical, mechanical, and compliance requirements. The tolerance specification differs (±5% versus ±10%), representing an improvement in precision. Physical dimensions vary within acceptable ranges for through-hole radial mounting applications. Operating temperature range extends to -55°C, providing enhanced low-temperature performance compared to the original part.

Engineering Selection Recommendations

DPPM20S15K-F Selection Criteria:

• Original equipment manufacturer (OEM) specification requirement
• Established supply chain with 682 units in stock
• ±10% tolerance acceptable for application
• Standard operating temperature range (-40°C to 105°C) sufficient
• CDE manufacturer preference or contractual requirement

R73UR2150SE00J Selection Criteria:

• Tighter tolerance specification (±5%) required for precision applications
• Extended low-temperature operation (-55°C) required
• Lower profile design (0.791" seated height) required for space-constrained layouts
• KEMET manufacturer preference or alternative sourcing strategy
• Higher inventory availability (1707 units in stock) for supply assurance
• Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility

Both parts are active products with confirmed production status and full compliance certifications. Selection between these parts depends on specific application requirements regarding tolerance, temperature range, and physical dimensions rather than electrical performance or regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can R73UR2150SE00J replace DPPM20S15K-F in all applications?

A: Yes, R73UR2150SE00J meets all critical electrical and mechanical requirements for substitution. The ±5% tolerance is tighter than the original ±10%, and the extended temperature range (-55°C to 105°C) covers the original operating range. Physical dimensions vary slightly but remain compatible with through-hole radial mounting. Both parts are ROHS3 compliant and REACH unaffected.

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

A: The primary differences are tolerance specification (±5% versus ±10%), operating temperature range (-55°C to 105°C versus -40°C to 105°C), and physical dimensions. The R73UR2150SE00J has a lower seated height (0.791" versus 1.024") and narrower width (0.433" versus 0.630"), making it suitable for space-constrained applications. Electrical performance and voltage ratings are identical.

Q: Are the lead spacings compatible with the same PCB footprint?

A: Lead spacing differs slightly between parts (1.043" for DPPM20S15K-F versus 1.083" for R73UR2150SE00J). This 0.040" difference may require PCB footprint verification for applications with tight layout constraints. Standard through-hole radial capacitor footprints typically accommodate this variation.

Q: Do both parts meet regulatory compliance requirements?

A: Yes, both DPPM20S15K-F and R73UR2150SE00J are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components in regulated markets.

Q: Which part should be selected for new designs?

A: Selection depends on specific design requirements. For applications requiring tighter tolerance or extended low-temperature operation, R73UR2150SE00J is appropriate. For applications matching the original DPPM20S15K-F specifications, either part is suitable based on availability and sourcing strategy.

Q: Are there any thermal performance differences?

A: Both parts operate across overlapping temperature ranges with identical maximum operating temperature (105°C). The R73UR2150SE00J extends the minimum operating temperature to -55°C compared to -40°C for the DPPM20S15K-F, providing enhanced performance in cold environments.
