ECE-P2AP183HA Equivalent & Substitute Parts

Part Overview

The ECE-P2AP183HA is an 18000 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 and voltage ratings. The part is currently obsolete, making equivalent substitute components necessary for ongoing system support and new designs requiring compatible specifications.

Substitute Part Grouping Explanation

Substitution for the ECE-P2AP183HA is determined by strict equivalence across the following electrical and mechanical parameters:

• Capacitance: 18000 µF (exact match required)
• Voltage Rating: 100 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package Type: Radial, Can - Snap-In - 5 Lead (exact match required)
• Mounting Type: Through Hole (exact match required)
• Operating Temperature Range: -40°C ~ 85°C (exact match required)
• Lifetime @ Temperature: 3000 Hrs @ 85°C (exact match required)
• Polarization: Polar (exact match required)
• Physical Dimensions: 1.969" Dia (50.00mm) and compatible height (maximum 3.228")

The Cornell Dubilier Electronics (CDE) 382LX series parts meet all substitution criteria. Both 382LX183M100B082V and 382LX183M100B082VS variants are electrically and mechanically compatible with the ECE-P2AP183HA.

Parameter Comparison

Engineering Selection Recommendations

The Cornell Dubilier Electronics 382LX183M100B082V and 382LX183M100B082VS are direct functional equivalents to the obsolete ECE-P2AP183HA. Both CDE parts are currently in active production status, ensuring long-term availability and supply chain continuity.

The 382LX183M100B082VS variant is packaged in bulk format, while the 382LX183M100B082V is supplied in standard packaging. Both variants are ROHS3 compliant and REACH unaffected, meeting modern regulatory requirements. The slight height increase (3.228" versus 3.150") remains within acceptable mechanical tolerances for standard through-hole PCB layouts.

Selection between the two CDE variants depends on packaging and procurement requirements rather than electrical or mechanical performance differences.

Frequently Asked Questions (FAQ)

Q: Can the 382LX183M100B082V and 382LX183M100B082VS be used interchangeably?

A: Yes. Both parts are electrically and mechanically identical. The only difference is packaging format (bulk versus standard). Selection depends on procurement and inventory management needs.

Q: What is the impact of the height difference between the original part and substitutes?

A: The ECE-P2AP183HA has a maximum seated height of 3.150" (80.00mm), while the CDE substitutes measure 3.228" (82.00mm). This 0.078" (2.00mm) difference is within standard PCB design tolerances for through-hole components and does not affect electrical performance or mechanical fit in typical applications.

Q: Are the CDE substitutes compliant with current regulatory standards?

A: Yes. Both 382LX183M100B082V and 382LX183M100B082VS are ROHS3 compliant and REACH unaffected, meeting current environmental and safety regulations.

Q: What is the difference in ripple current specifications at high frequency?

A: The original ECE-P2AP183HA specifies 12.65 A @ 10 kHz, while the CDE substitutes specify 12.65 A @ 20 kHz. Both maintain the same ripple current magnitude; the CDE parts are rated at a higher frequency, indicating equivalent or superior performance characteristics.

Q: Is the ESR specification critical for substitution?

A: The ECE-P2AP183HA specifies 18 mOhm @ 120Hz ESR. The CDE substitutes do not provide ESR data in the available specifications. However, both parts meet all other electrical and mechanical requirements for direct substitution in general purpose applications.
