Key Parameters

Substitute Part Grouping Explanation

Substitution for the ECE-P2WA122HA is determined by strict equivalence across the following critical parameters:

• Capacitance: 1200 µF (exact match required)
• Voltage Rating: 450 V (exact match required)
• Tolerance: ±20% (exact match required)
• ESR: 152 mOhm (exact match required)
• Lifetime: 3000 Hrs @ 105°C (exact match required)
• Operating Temperature: -25°C ~ 105°C (exact match required)
• Package Type: Radial, Can - Snap-In - 5 Lead (exact match required)
• Mounting: Through Hole (exact match required)
• Polarization: Polar (exact match required)
• Case Diameter: 1.969" (50.00 mm) (exact match required)

The substitute part 383LX122M450B082VS from Cornell Dubilier Electronics meets all critical electrical and mechanical parameters. Minor variations in height (3.228" vs. 3.150") and ripple current frequency response do not affect functional equivalence for general-purpose applications.

Engineering Selection Recommendations

The 383LX122M450B082VS from Cornell Dubilier Electronics is a direct functional equivalent to the obsolete ECE-P2WA122HA. Selection is based on the following factors:

• All critical electrical parameters match exactly: capacitance, voltage rating, tolerance, ESR, and thermal lifetime specifications.
• Mechanical compatibility is confirmed through identical package type, mounting method, and case diameter.
• The substitute part is currently in active production status, ensuring availability and supply chain continuity.
• The Cornell Dubilier part carries ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements.
• Height variation (2 mm difference) is within acceptable mechanical tolerance for through-hole snap-in applications and does not affect electrical performance.
• Both parts share identical ECCN and HTSUS classifications, confirming trade compliance equivalence.

Frequently Asked Questions (FAQ)

Q: Can the 383LX122M450B082VS be used as a direct replacement for the ECE-P2WA122HA?

A: Yes. The substitute part meets all critical electrical and mechanical specifications. The 2 mm height difference does not affect functionality in general-purpose applications using snap-in mounting.

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

A: The ECE-P2WA122HA has a maximum seated height of 3.150" (80.00 mm), while the 383LX122M450B082VS measures 3.228" (82.00 mm). This 2 mm variation is within acceptable tolerance for through-hole snap-in capacitor applications and does not impact electrical performance or standard PCB layouts.

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

A: The substitute part (383LX122M450B082VS) carries ROHS3 compliance and REACH unaffected status, providing enhanced regulatory alignment compared to the obsolete original part. Both parts share identical ECCN (EAR99) and HTSUS (8532.22.0055) classifications.

Q: What parameters must remain identical for substitution to be valid?

A: Capacitance (1200 µF), voltage rating (450 V), tolerance (±20%), ESR (152 mOhm), thermal lifetime (3000 Hrs @ 105°C), operating temperature range (-25°C ~ 105°C), package type (Radial, Can - Snap-In - 5 Lead), and mounting method (Through Hole) must all match exactly.

Q: Is the ripple current specification difference significant?

A: The ripple current at high frequency differs slightly in test frequency (10 kHz vs. 20 kHz), but both parts deliver 6.58 A at their respective test frequencies. This variation reflects different measurement standards and does not affect functional equivalence for general-purpose applications.

Q: What is the inventory status for the substitute part?

A: The 383LX122M450B082VS is currently in active production with 648 pieces of new original stock available, ensuring reliable supply for replacement and new design applications.
