Key Parameters

Substitute Part Grouping Explanation

Substitution of the WMF6P47K-F is determined by strict equivalence in the following electrical and mechanical parameters:

Critical Matching Parameters:

• Capacitance value: 0.47 µF (exact match required)
• DC voltage rating: 630V (minimum requirement)
• Tolerance: ±10% (acceptable range for general-purpose applications)
• Dielectric material: Polyester (functional equivalence)
• Mounting type: Through Hole (mechanical compatibility)
• Package configuration: Axial (form factor requirement)
• Termination style: PC Pins (circuit board interface)

The substitute part 474MWR630K meets all critical electrical specifications and mechanical requirements. Both parts share identical capacitance, tolerance, DC voltage rating, dielectric material family, mounting type, package style, and termination configuration. Physical dimensions differ, but both maintain axial through-hole compatibility with standard PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

Both the WMF6P47K-F and 474MWR630K are Active products with ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component manufacturing and use.

WMF6P47K-F Selection Criteria:

• Applications requiring extended low-temperature operation below -40°C
• Designs with space constraints accommodating larger axial form factors (22.50mm diameter)
• Specifications explicitly requiring standard polyester dielectric without metallization

474MWR630K Selection Criteria:

• Applications operating within -40°C to 105°C temperature range
• Space-constrained designs benefiting from compact form factor (15.50mm diameter)
• General-purpose applications where metallized polyester dielectric is acceptable
• Designs where low ESR (3.01 Ohms) provides performance advantages

Both parts are suitable for general-purpose applications with identical electrical performance at rated specifications. Selection between these parts depends on physical space availability, temperature operating range requirements, and form factor constraints within the target application.

Frequently Asked Questions (FAQ)

Q: Can the 474MWR630K directly replace the WMF6P47K-F in all applications?

A: The 474MWR630K provides electrical equivalence in capacitance, tolerance, and DC voltage rating. Physical dimensions differ significantly (15.50mm vs. 22.50mm diameter), requiring verification of PCB layout space and lead spacing compatibility. Operating temperature range differs; the 474MWR630K operates to 105°C maximum versus 125°C for the WMF6P47K-F. Applications requiring temperatures above 105°C require the WMF6P47K-F.

Q: What is the difference between polyester and metallized polyester dielectric?

A: Both are polyester-based dielectric materials. The 474MWR630K uses metallized polyester, which incorporates a thin metal layer. This construction contributes to the lower ESR specification (3.01 Ohms) of the 474MWR630K. Both materials are functionally compatible for general-purpose capacitor applications at the specified voltage and capacitance ratings.

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

A: The WMF6P47K-F operates to 125°C maximum, making it suitable for higher-temperature environments. The 474MWR630K operates to 105°C maximum. Application temperature requirements determine which part is appropriate.

Q: Do physical dimension differences affect circuit board compatibility?

A: Yes. The WMF6P47K-F measures 22.50mm in diameter and 50.80mm in length, while the 474MWR630K measures 15.50mm in diameter and 34.00mm in length. PCB layout, component spacing, and mechanical clearance requirements must accommodate the selected part's physical dimensions. Both maintain axial through-hole mounting compatibility with standard PCB hole patterns.

Q: Are both parts RoHS compliant?

A: Yes. Both the WMF6P47K-F and 474MWR630K are ROHS3 Compliant and REACH Unaffected, meeting current regulatory requirements for electronic component use in regulated markets.
