Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DPM6S33K-F is determined by the following critical parameters:

Mandatory Matching Parameters:

• Capacitance: 0.033 µF (exact match required)
• Voltage Rating - DC: 630V (minimum requirement)
• Dielectric Material: Polypropylene (PP), Metallized
• Mounting Type: Through Hole
• Package Type: Radial
• Lead Spacing: 0.591" (15.00mm)
• Termination: PC Pins

Allowable Variation Parameters:

• Tolerance: ±10% or tighter (±5% acceptable)
• Voltage Rating - AC: 250V or higher
• Physical dimensions: Minor variations acceptable within PCB layout constraints
• Height - Seated: Variations acceptable if within board clearance

The R73PI23304000J from KEMET meets all mandatory matching parameters and demonstrates tighter tolerance specification (±5%), making it a direct electrical equivalent with enhanced precision characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the DPM6S33K-F and R73PI23304000J are Active status products with full RoHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component deployment.

The DPM6S33K-F remains the primary selection for applications requiring the specified ±10% tolerance and CDE manufacturer qualification. The R73PI23304000J serves as a direct electrical equivalent with the following distinctions:

• Enhanced tolerance specification (±5% versus ±10%) provides improved capacitance accuracy
• Higher AC voltage rating (300V versus 250V) expands operational envelope
• Reduced seated height (14.60mm versus 16.00mm) accommodates tighter PCB spacing
• AEC-Q200 automotive qualification available for automotive-grade applications
• Marginally wider body dimension (8.50mm versus 8.00mm) requires PCB layout verification

Both parts maintain identical DC voltage rating (630V), capacitance value (0.033 µF), lead spacing (15.00mm), and operating temperature range (-55°C to 105°C), ensuring functional interchangeability in DC link and DC filtering circuits.

Frequently Asked Questions (FAQ)

Q: Can R73PI23304000J replace DPM6S33K-F in all applications?

A: Yes, for applications where the specified parameters match. Both parts share identical capacitance (0.033 µF), DC voltage rating (630V), dielectric material (polypropylene metallized), lead spacing (15.00mm), and operating temperature range (-55°C to 105°C). The R73PI23304000J offers tighter tolerance (±5%) and higher AC rating (300V), making it suitable for equivalent or enhanced performance requirements.

Q: What is the impact of tolerance difference (±10% versus ±5%)?

A: Tolerance defines the allowable deviation from the nominal capacitance value. The DPM6S33K-F permits ±10% variation, while R73PI23304000J permits ±5% variation. For applications requiring precise capacitance values, the R73PI23304000J provides superior accuracy. Both tolerances are acceptable for general DC filtering and DC link applications.

Q: Are there physical dimension concerns when substituting?

A: Lead spacing is identical (15.00mm), ensuring PCB footprint compatibility. The R73PI23304000J is slightly wider (8.50mm versus 8.00mm) and shorter (14.60mm versus 16.00mm). Verify PCB layout clearances for the width dimension and confirm vertical clearance is not compromised by the reduced height.

Q: Do both parts meet current compliance standards?

A: Yes. Both DPM6S33K-F and R73PI23304000J are RoHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component use in regulated markets.

Q: What applications are these parts suitable for?

A: Both parts are specified for DC link filtering, DC filtering, high frequency switching, and switching applications. The R73PI23304000J additionally carries AEC-Q200 automotive qualification, extending suitability to automotive-grade circuit designs.
