474MMR630KG Film Capacitor - Equivalent & Substitute Parts

Part Overview

The 474MMR630KG is a 0.47 µF film capacitor manufactured by Cornell Dubilier / Illinois Capacitor, currently in active production status. This metallized polyester radial capacitor is rated for 630VDC / 220VAC operation and is designed for general-purpose applications. Alternative equivalent models are necessary when the primary part becomes unavailable, when bulk packaging is preferred, or when inventory requirements necessitate sourcing from available stock channels.

Key Parameters

Substitute Part Grouping Explanation

The 474MMR630K is a parametric equivalent to the 474MMR630KG within the MMR series. Substitution compatibility is determined strictly by the following parameters:

Critical Parameters (Must Match Exactly):

• Capacitance: 0.47 µF
• Tolerance: ±10%
• Voltage Rating - DC: 630V
• Voltage Rating - AC: 220V
• Dielectric Material: Polyester, Metallized
• Mounting Type: Through Hole
• Package Type: Radial
• Termination: PC Pins
• Lead Spacing: 0.886" (22.50 mm)

Physical & Operating Parameters (Must Match):

• Operating Temperature Range: -40°C to 105°C
• Dimensions: 1.024" L x 0.394" W (26.00 mm x 10.00 mm)
• Height - Seated (Max): 0.748" (19.00 mm)

The primary distinction between the main part and the substitute is packaging format. The 474MMR630KG is supplied in standard packaging, while the 474MMR630K is supplied in bulk packaging.

Parameter Comparison

Engineering Selection Recommendations

Both the 474MMR630KG and 474MMR630K are ROHS3 compliant and REACH unaffected, meeting contemporary environmental and regulatory standards. Both parts are in active production status, ensuring continued availability. The selection between these parts should be based on inventory logistics and packaging requirements rather than electrical or mechanical performance, as all functional parameters are identical. The 474MMR630K in bulk packaging offers higher inventory availability (1784 pieces in stock) compared to the standard-packaged 474MMR630KG (1089 pieces in stock).

Frequently Asked Questions (FAQ)

Can 474MMR630K be used as a direct replacement for 474MMR630KG?

Yes. Both parts are electrically and mechanically identical, with matching capacitance (0.47 µF), voltage ratings (630VDC / 220VAC), tolerance (±10%), physical dimensions, lead spacing, and thermal characteristics. The only difference is packaging format.

What determines substitution eligibility for 474MMR630KG?

A substitute part must match the following critical parameters: 0.47 µF capacitance, ±10% tolerance, 630VDC voltage rating, 220VAC voltage rating, polyester metallized dielectric, through-hole mounting, radial package type, PC pin termination, 22.50 mm lead spacing, and operating temperature range of -40°C to 105°C. Physical dimensions (26.00 mm x 10.00 mm length x width and 19.00 mm maximum seated height) must also match.

Are there any compatibility concerns when using bulk-packaged 474MMR630K instead of standard-packaged 474MMR630KG?

No compatibility concerns exist. The parts are electrically and mechanically equivalent. Bulk packaging refers only to the outer distribution packaging and does not affect component performance or installation.

What regulatory compliance standards apply to these parts?

Both parts are ROHS3 compliant and REACH unaffected. Both carry EAR99 export classification.
