ECE-P2EP472HA Equivalent & Substitute Parts

Part Overview

The ECE-P2EP472HA is a 4700 µF, 250 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components. This radial, can-style snap-in capacitor with 5 leads is designed for general-purpose applications requiring high capacitance and voltage ratings. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECE-P2EP472HA is determined by strict equivalence across the following parameters:

• Capacitance: 4700 µF (exact match required)
• Voltage Rating: 250 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package / Case: Radial, Can - Snap-In - 5 Lead (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Lifetime @ Temperature: 3000 Hrs @ 85°C (exact match required)
• Polarization: Polar (exact match required)

The substitute part 382LX472M250B082V, manufactured by Cornell Dubilier Electronics (CDE), meets all critical electrical and mechanical parameters for direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The 382LX472M250B082V from Cornell Dubilier Electronics is a direct functional equivalent to the obsolete ECE-P2EP472HA. Both parts share identical electrical specifications and mechanical form factors suitable for through-hole mounting in snap-in applications.

The CDE substitute offers the advantage of active product status, ensuring ongoing availability and supply chain continuity. The part is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement.

Physical dimensions are compatible for PCB mounting, with the substitute height of 3.228" (82.00mm) representing a 2.48% increase over the original 3.150" (80.00mm). This minor dimensional variance is within typical mechanical tolerances for snap-in capacitor installations.

Frequently Asked Questions (FAQ)

Q: Can the 382LX472M250B082V replace the ECE-P2EP472HA in existing designs?

A: Yes. Both parts are electrically and mechanically equivalent across all critical parameters: 4700 µF capacitance, 250 V rating, ±20% tolerance, identical package type, and matching operating temperature range. The snap-in 5-lead configuration and through-hole mounting are identical.

Q: What is the significance of the height difference between the two parts?

A: The substitute part is 2.48% taller (82.00mm vs. 80.00mm). This difference is within standard mechanical tolerances for radial can capacitors and does not affect electrical performance or typical PCB layout compatibility for snap-in installations.

Q: Why is the original ECE-P2EP472HA listed as obsolete?

A: Panasonic has discontinued this part number. The CDE 382LX472M250B082V provides functional continuity for applications requiring this capacitance and voltage specification.

Q: Are there compliance differences between the two parts?

A: The CDE substitute is ROHS3 compliant and REACH unaffected. The original part's compliance status is not specified in available documentation. Both parts carry the same ECCN (EAR99) and HTSUS (8532.22.0055) classifications.

Q: What ripple current specifications apply to each part?

A: Both parts support 9.65 A ripple current at 120 Hz. At high frequency, the original supports 14.61 A @ 10 kHz, while the substitute supports 14.61 A @ 20 kHz. Both ratings are suitable for general-purpose applications.
