Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 474MPR630K are identified based on the following critical parameters that determine functional equivalence:

Electrical Parameters (Must Match):

• Capacitance value: 0.47 µF
• Tolerance: ±10%
• Voltage rating (DC): 630V minimum
• Voltage rating (AC): 250V minimum

Mechanical Parameters (Must Match):

• Mounting type: Through Hole
• Package type: Radial
• Termination: PC Pins

Compliance Parameters (Must Match):

• RoHS3 Compliant status
• REACH Unaffected status

The ECQ-E6474KF from Panasonic Electronic Components meets all critical electrical and mechanical requirements. While the dielectric material differs (polyester versus polypropylene) and physical dimensions vary, both parts satisfy the functional requirements for 630V DC, 0.47 µF radial film capacitor applications.

Frequently Asked Questions (FAQ)

Q: Can ECQ-E6474KF replace 474MPR630K in all applications?

A: ECQ-E6474KF meets the electrical requirements (0.47 µF, ±10%, 630V DC, 250V AC) and compliance standards. However, physical dimensions and lead spacing differ. PCB layout compatibility must be verified before substitution. The operating temperature range of ECQ-E6474KF is limited to -40°C minimum, compared to -55°C for 474MPR630K.

Q: What are the key differences between these parts?

A: The primary differences are dielectric material (polypropylene versus polyester), physical dimensions, lead spacing, and operating temperature range. Electrical specifications and voltage ratings are identical.

Q: Are both parts RoHS3 compliant?

A: Yes, both 474MPR630K and ECQ-E6474KF are ROHS3 compliant and REACH unaffected.

Q: Does the dielectric material difference affect performance?

A: Dielectric material selection affects ESR, temperature stability, and frequency response characteristics. The 474MPR630K specifies polypropylene with low ESR for DC link applications. The ECQ-E6474KF uses polyester for general purpose applications. Application-specific requirements determine material suitability.

Q: Can these parts be used interchangeably on the same PCB?

A: Physical dimensions and lead spacing differ significantly. PCB hole patterns and component placement must accommodate the specific part dimensions. Direct board-level interchange without layout modification is not possible.

Q: What is the lead spacing difference?

A: 474MPR630K has 1.083" (27.50mm) lead spacing. ECQ-E6474KF has 0.886" (22.50mm) lead spacing. This difference requires PCB design verification before substitution.
