Substitute Part Grouping Explanation

Substitution eligibility for the DMM6P33K-F is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part DME6P33K-F qualifies based on the following criteria:

Electrical Equivalence:

• Capacitance value: 0.33 µF (exact match)
• DC voltage rating: 630V (exact match)
• AC voltage rating: 250V (exact match)
• Tolerance: ±10% (exact match)
• Dielectric composition: Polyester, Metallized (exact match)
• Operating temperature range: -55°C to 125°C (exact match)

Mechanical Compatibility:

• Mounting technology: Through Hole (exact match)
• Termination style: PC Pins (exact match)
• Package type: Radial (exact match)

Regulatory Compliance:

• RoHS3 Compliant (exact match)
• REACH Unaffected status (exact match)
• ECCN classification: EAR99 (exact match)

The primary distinction between DMM6P33K-F and DME6P33K-F lies in physical dimensions and series designation. The DME6P33K-F represents a more compact form factor within the same product family, with reduced length, width, and height specifications while maintaining identical electrical performance.

Engineering Selection Recommendations

DMM6P33K-F Selection Criteria:

• Applications requiring standard form factor dimensions with 1.083" lead spacing
• PCB layouts designed for larger component footprints
• Designs where the 31.00mm length and 13.00mm width specifications are specified
• Existing inventory or supply chain established for DMM series components

DME6P33K-F Selection Criteria:

• Space-constrained applications requiring compact component placement
• PCB designs with reduced lead spacing requirements (22.50mm)
• Applications benefiting from lower profile mounting (19.00mm maximum height)
• Designs where the 26.00mm length and 8.00mm width specifications are preferred
• Bulk packaging requirements

Both parts maintain identical electrical performance, temperature operating range, voltage ratings, and regulatory compliance status. Selection between DMM6P33K-F and DME6P33K-F is determined solely by physical space constraints and PCB layout requirements. The substitute relationship is bidirectional when mechanical constraints permit.

Frequently Asked Questions (FAQ)

Q: Can DME6P33K-F replace DMM6P33K-F in any application?

A: DME6P33K-F provides electrical equivalence with identical capacitance, voltage ratings, tolerance, and operating temperature range. Substitution is valid when PCB layout accommodates the reduced dimensions (26.00mm length, 8.00mm width, 22.50mm lead spacing) and lower profile (19.00mm height). Physical space constraints are the only limiting factor.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts utilize identical polyester metallized dielectric technology, maintain 630V DC and 250V AC ratings, and operate across -55°C to 125°C. Electrical behavior, capacitance stability, and frequency response are equivalent.

Q: What is the significance of the series designation change from DMM to DME?

A: The series designation reflects Cornell Dubilier Electronics' product line organization. DMM and DME series both represent 0.33 µF film capacitors with identical electrical specifications. The series change correlates with physical form factor optimization, with DME representing a more compact design within the same electrical performance class.

Q: Do both parts have identical regulatory compliance?

A: Yes. Both DMM6P33K-F and DME6P33K-F carry ROHS3 Compliant status, REACH Unaffected designation, and EAR99 ECCN classification. Regulatory requirements are satisfied by either part.

Q: What packaging differences exist between these parts?

A: DMM6P33K-F is supplied in standard packaging configuration. DME6P33K-F is available in Bulk packaging. Both maintain identical component specifications; packaging format differs based on supply requirements.

Q: Can I use DMM6P33K-F in a design originally specified for DME6P33K-F?

A: Substitution is valid when PCB layout accommodates the larger dimensions. DMM6P33K-F measures 31.00mm length and 13.00mm width with 27.50mm lead spacing, compared to DME6P33K-F at 26.00mm length, 8.00mm width, and 22.50mm lead spacing. Verify PCB hole spacing and component clearance before substitution.

Q: What is the lead spacing specification and why does it matter?

A: Lead spacing refers to the distance between the two radial pins. DMM6P33K-F has 1.083" (27.50mm) spacing; DME6P33K-F has 0.886" (22.50mm) spacing. This dimension is critical for PCB hole pattern compatibility and must match the design specification to ensure proper mounting.

Q: Are both parts suitable for high-voltage applications?

A: Yes. Both parts are rated for 630V DC and 250V AC operation, making them suitable for high-voltage general-purpose applications within these voltage specifications.
