ECE-P1KA123HA Equivalent & Substitute Parts

Part Overview

The ECE-P1KA123HA is a 12000 µF, 80 V aluminum electrolytic capacitor manufactured by Panasonic Electronic Components in the T-HA series. 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 functionally equivalent alternatives essential for ongoing system support and procurement planning.

Substitute Part Grouping Explanation

Substitution of the ECE-P1KA123HA is determined by strict equivalence across the following critical parameters:

Capacitance value: 12000 µF (exact match required)
Voltage rating: 80 V (exact match required)
Tolerance: ±20% (exact match required)
ESR: 35 mOhm (exact match required)
Lifetime rating: 3000 Hrs @ 105°C (exact match required)
Operating temperature range: -40°C ~ 105°C (exact match required)
Package type: Radial, Can - Snap-In - 5 Lead (exact match required)
Mounting type: Through Hole (exact match required)
Polarization: Polar (exact match required)

The substitute part 383LX123M080B052VS from Cornell Dubilier Electronics (CDE) meets all critical electrical and mechanical parameters, with minor dimensional variance in seated height (52.00 mm vs. 50.00 mm) that remains within acceptable tolerance for snap-in mounting applications.

Engineering Selection Recommendations

The 383LX123M080B052VS from Cornell Dubilier Electronics is a direct functional equivalent to the obsolete ECE-P1KA123HA. Selection of this substitute is supported by:

Exact electrical parameter matching across capacitance, voltage, tolerance, ESR, and thermal lifetime specifications
Identical package configuration and mounting interface (Radial, Can - Snap-In - 5 Lead, Through Hole)
Active product status ensuring ongoing availability and supply chain continuity
ROHS3 compliance certification, meeting current regulatory requirements
Minimal dimensional variance in seated height (2 mm difference) that does not affect mechanical fit in standard snap-in mounting applications

The substitute part is suitable for direct replacement in applications previously specified for the ECE-P1KA123HA without circuit redesign or performance degradation.

Frequently Asked Questions (FAQ)

Q: Can the 383LX123M080B052VS replace the ECE-P1KA123HA in all applications?

A: Yes. Both parts share identical electrical specifications (12000 µF, 80 V, ±20%, 35 mOhm ESR, 3000 Hrs @ 105°C) and the same package configuration (Radial, Can - Snap-In - 5 Lead). The 2 mm difference in seated height does not affect compatibility with standard snap-in mounting hardware.

Q: What is the significance of the product status difference?

A: The ECE-P1KA123HA is classified as obsolete, meaning Panasonic no longer manufactures or supports this part. The 383LX123M080B052VS maintains active status from Cornell Dubilier Electronics, ensuring continued availability, technical support, and supply chain reliability.

Q: Are there compliance differences between these parts?

A: The 383LX123M080B052VS is certified ROHS3 compliant and REACH unaffected. The ECE-P1KA123HA specifications do not include these certifications. For applications requiring regulatory compliance documentation, the substitute part provides current certification status.

Q: How do the ripple current ratings compare?

A: Both parts deliver 6.03 A ripple current at 120 Hz. At high frequency, the ECE-P1KA123HA is rated 6.935 A @ 10 kHz, while the 383LX123M080B052VS is rated 6.93 A @ 20 kHz. These values are equivalent for practical circuit applications.

Q: What is the lead spacing for these parts?

A: Lead spacing is specified as 0.984" (25.00 mm) for the ECE-P1KA123HA. This parameter is not provided for the 383LX123M080B052VS; however, both parts use identical snap-in mounting interfaces, ensuring mechanical compatibility.
