ECE-P2AP273HA Equivalent & Substitute Parts

Part Overview

The ECE-P2AP273HA is a 27000 µF, 100 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 at moderate voltage ratings. The part is classified as obsolete, making identification of compatible substitute components essential for ongoing system support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ECE-P2AP273HA is determined by strict alignment of the following critical parameters:

• Capacitance value: 27000 µF (exact match required)
• Voltage rating: 100 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)

The substitute part 382LX273M100B102VS meets all critical substitution criteria. Both parts share identical capacitance, voltage, tolerance, package type, mounting configuration, and thermal specifications. Physical dimensions remain compatible within acceptable tolerances for through-hole snap-in applications.

Parameter Comparison

Engineering Selection Recommendations

The 382LX273M100B102VS from Cornell Dubilier Electronics is a direct functional equivalent to the obsolete ECE-P2AP273HA. Selection of this substitute is supported by:

• Identical electrical specifications across all critical parameters (capacitance, voltage, tolerance, ripple current at 120 Hz)
• Matching mechanical form factor and mounting configuration for direct board-level replacement
• Active product status ensuring ongoing availability and supply chain continuity
• ROHS3 compliance certification, meeting current environmental and regulatory requirements
• Equivalent thermal performance with identical 3000-hour lifetime rating at 85°C

The substitute part accommodates the minor height variation (107.00mm vs. 105.00mm) within typical through-hole snap-in assembly tolerances. The higher ripple current frequency specification (20 kHz vs. 10 kHz) represents an enhanced performance characteristic.

Frequently Asked Questions (FAQ)

Q: Can the 382LX273M100B102VS replace the ECE-P2AP273HA in existing designs?

A: Yes. Both parts share identical capacitance (27000 µF), voltage rating (100 V), tolerance (±20%), package configuration (Radial, Can - Snap-In - 5 Lead), and thermal specifications (3000 Hrs @ 85°C). The physical dimensions are compatible for through-hole snap-in mounting.

Q: What is the height difference between these parts?

A: The ECE-P2AP273HA has a maximum seated height of 4.134" (105.00mm), while the 382LX273M100B102VS measures 4.213" (107.00mm). This 2.09mm difference falls within acceptable tolerances for through-hole snap-in applications and does not affect electrical performance or board-level compatibility.

Q: Are there compliance differences between the original and substitute?

A: The substitute part (382LX273M100B102VS) carries ROHS3 compliance certification. The original part's compliance status is not specified in available documentation. For applications requiring specific regulatory compliance, the substitute's ROHS3 status provides assurance of environmental and material standards adherence.

Q: Is the ripple current specification different?

A: Both parts support 12.53 A ripple current at 120 Hz. The high-frequency ripple current specification differs: the original supports 14.41 A @ 10 kHz, while the substitute supports 14.41 A @ 20 kHz. This represents equivalent or enhanced performance for high-frequency ripple current handling.

Q: Why is the original part listed as obsolete?

A: The ECE-P2AP273HA is classified as obsolete by Panasonic Electronic Components. The 382LX273M100B102VS maintains active product status, ensuring continued availability, technical support, and supply chain reliability for new procurements and system maintenance.
