Parameter Comparison

Engineering Selection Recommendations

The 383LX273M080B102VS from Cornell Dubilier Electronics is a qualified direct substitute for the obsolete ECE-P1KA273HA. The substitute part maintains electrical equivalence across all specified parameters, including capacitance, voltage rating, tolerance, ESR, and thermal lifetime ratings.

The substitute part offers the advantage of active product status, ensuring continued availability and supply chain reliability. Additionally, the 383LX273M080B102VS carries ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements for new production applications.

The height difference of 0.079" (2.00 mm) between the seated heights must be evaluated within the context of the specific application's mechanical constraints and PCB layout requirements.

Frequently Asked Questions (FAQ)

Q: Can the 383LX273M080B102VS be used as a direct replacement for the ECE-P1KA273HA?

A: Yes. Both parts share identical electrical specifications (27000 µF, 80 V, ±20% tolerance, 18 mOhm ESR, 3000 Hrs @ 105°C) and mechanical packaging (Radial, Can - Snap-In - 5 Lead, Through Hole mounting, 1.969" diameter). The substitute part is electrically and mechanically compatible.

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

A: The ECE-P1KA273HA has a maximum seated height of 4.134" (105.00 mm), while the 383LX273M080B102VS measures 4.213" (107.00 mm). This 0.079" (2.00 mm) difference must be verified against available clearance in the target application's enclosure or PCB assembly to ensure mechanical fit.

Q: Why is the ECE-P1KA273HA listed as obsolete?

A: Panasonic has discontinued this part number. The 383LX273M080B102VS from Cornell Dubilier Electronics is an active equivalent that provides the same electrical and mechanical functionality for ongoing system support and new production designs.

Q: Are there compliance differences between these parts?

A: The 383LX273M080B102VS carries ROHS3 compliance and REACH unaffected status. The ECE-P1KA273HA compliance information is not specified in the available data. For applications requiring regulatory compliance documentation, the substitute part provides explicit certification.

Q: What parameters determine substitution eligibility for this capacitor?

A: Substitution is based on matching capacitance (27000 µF), voltage rating (80 V), tolerance (±20%), ESR (18 mOhm), thermal lifetime (3000 Hrs @ 105°C), operating temperature range (-40°C ~ 105°C), polarization (Polar), and package type (Radial, Can - Snap-In - 5 Lead, Through Hole mounting).
