Equivalent & Substitute Parts for ECE-P2EP272HA

Part Overview

The ECE-P2EP272HA is a 2700 µF, 250 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components in the T-UP series. 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 currently obsolete, making identification of suitable substitute components essential for ongoing system support and procurement planning.

Substitute Part Grouping Explanation

Substitution eligibility for the ECE-P2EP272HA is determined by strict alignment with the following electrical and mechanical parameters:

Capacitance: 2700 µF (exact match required)
Voltage Rating: 250 V (exact match required)
Tolerance: ±20% (exact match required)
Package Configuration: Radial, Can - Snap-In - 5 Lead (exact match required)
Mounting Type: Through Hole (exact match required)
Operating Temperature Range: -40°C ~ 85°C (minimum requirement)
Lifetime Specification: 3000 Hrs @ 85°C (minimum requirement)
Polarization: Polar (exact match required)
Physical Diameter: 1.969" (50.00mm) (exact match required)

The substitute parts identified below meet all critical electrical and mechanical parameters. Variations in height and ESR specifications do not preclude substitution when all primary parameters align.

Engineering Selection Recommendations

Both Cornell Dubilier Electronics substitute parts (382LX272M250B052V and 382LX272M250B052VS) satisfy the electrical and mechanical requirements for direct substitution of the obsolete ECE-P2EP272HA.

The 382LX272M250B052VS variant is recommended as the primary choice due to its active product status and ROHS3 compliance certification, ensuring long-term availability and regulatory alignment. The 382LX272M250B052V remains a valid alternative with identical electrical specifications.

Both substitutes feature a maximum seated height of 2.047" (52.00mm), which exceeds the original part's 1.969" (50.00mm) height by 0.078" (2.00mm). This dimensional difference must be evaluated within the context of the specific application's physical constraints and PCB layout requirements.

Frequently Asked Questions (FAQ)

Q: Can the 382LX272M250B052V and 382LX272M250B052VS be used interchangeably with the ECE-P2EP272HA?

A: Yes. Both parts match the critical electrical parameters (2700 µF, 250 V, ±20% tolerance) and mechanical specifications (radial snap-in package, through-hole mounting, 50.00mm diameter). The height difference of 2.00mm must be accommodated in the design.

Q: What is the significance of the height difference between the original and substitute parts?

A: The substitute parts measure 2.047" (52.00mm) in seated height compared to the original 1.969" (50.00mm). This 2.00mm increase requires verification against PCB clearance, enclosure constraints, and component placement in the target application.

Q: Why is the 382LX272M250B052VS preferred over the 382LX272M250B052V?

A: The 382LX272M250B052VS carries ROHS3 compliance certification and maintains active product status, supporting long-term procurement and regulatory requirements. Both parts are electrically equivalent.

Q: Are there differences in ripple current handling between the original and substitutes?

A: The original ECE-P2EP272HA specifies 74 mOhm ESR at 120 Hz. The substitute parts do not provide ESR specifications in the available data. Both substitutes maintain the same ripple current rating at 120 Hz (6.77 A) and exceed the original specification at higher frequencies (7.79 A @ 20 kHz versus 9.478 A @ 10 kHz).

Q: What compliance certifications apply to the substitute parts?

A: The 382LX272M250B052VS is ROHS3 compliant and REACH unaffected. Both substitutes carry the same ECCN (EAR99) and HTSUS (8532.22.0055) classifications as the original part.
