Substitute Part Grouping Explanation

Substitute parts for the DMM6P47K-F are identified based on strict electrical and mechanical parameter equivalence within the Cornell Dubilier Electronics product portfolio. The substitution logic is based on the following criteria:

Electrical Equivalence Requirements:

Capacitance value: 0.47 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 ~ 125°C (exact match or better)

Mechanical Compatibility Requirements:

Mounting configuration: Through Hole Radial (exact match)
Termination style: PC Pins (exact match)
Package classification: Radial film capacitor (exact match)

Compliance Requirements:

RoHS3 compliance maintained
REACH unaffected status maintained
ECCN classification: EAR99 (exact match)

The DME6P47K-F qualifies as a direct substitute because it maintains all critical electrical parameters while belonging to the same product series family. Physical dimensions and lead spacing differ, but these variations remain within acceptable through-hole PCB mounting tolerances for general-purpose applications.

Engineering Selection Recommendations

Primary Selection - DMM6P47K-F: Select the DMM6P47K-F when PCB layout requires the larger form factor with 27.50mm lead spacing. This part is suitable for applications with standard through-hole spacing and where component density is not a constraint. Active product status ensures continued availability and supply chain stability.

Alternative Selection - DME6P47K-F: The DME6P47K-F serves as a direct electrical equivalent with identical capacitance, voltage ratings, tolerance, and temperature performance. This substitute features a more compact physical footprint (26.00mm x 10.00mm versus 31.00mm x 13.00mm) and reduced lead spacing (22.50mm versus 27.50mm), making it suitable for space-constrained PCB designs. Both parts maintain ROHS3 compliance and Active product status.

Substitution Feasibility: Substitution between DMM6P47K-F and DME6P47K-F is electrically and mechanically valid when PCB hole patterns accommodate the 22.50mm lead spacing of the DME6P47K-F. The smaller physical dimensions of the substitute part present no electrical performance degradation. Both parts are manufactured by the same supplier, ensuring consistent quality and reliability standards.

Frequently Asked Questions (FAQ)

Q: Can DME6P47K-F replace DMM6P47K-F in existing designs?

A: Yes, the DME6P47K-F is electrically equivalent with identical capacitance (0.47 µF), voltage ratings (630V DC / 250V AC), tolerance (±10%), and operating temperature range (-55°C ~ 125°C). PCB compatibility requires verification that the 22.50mm lead spacing of the DME6P47K-F matches the existing hole pattern, as the main part uses 27.50mm spacing.

Q: What are the key differences between these parts?

A: The primary differences are physical dimensions and lead spacing. The DMM6P47K-F measures 31.00mm x 13.00mm with 27.50mm lead spacing, while the DME6P47K-F measures 26.00mm x 10.00mm with 22.50mm lead spacing. All electrical specifications remain identical.

Q: Are both parts RoHS3 compliant?

A: Yes, both DMM6P47K-F and DME6P47K-F are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Which part should I select for new designs?

A: For new designs, either part is acceptable based on PCB layout requirements. The DME6P47K-F offers space savings with its compact footprint, while the DMM6P47K-F accommodates standard through-hole spacing. Both maintain Active product status with Cornell Dubilier Electronics.

Q: Do these parts have different moisture sensitivity levels?

A: The DMM6P47K-F has MSL 1 (Unlimited), while the DME6P47K-F lists MSL as Not Applicable. Both classifications indicate minimal moisture sensitivity for film capacitor construction.

Q: Are there inventory considerations for substitution?

A: The DME6P47K-F currently has higher inventory availability (1848 Pcs) compared to the DMM6P47K-F (926 Pcs). This may influence supply chain decisions for high-volume applications.
