ECE-V2AA4R7P Equivalent & Substitute Parts

Part Overview

The ECE-V2AA4R7P is a 4.7 µF, 100 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Panasonic Electronic Components. This part is classified as obsolete, making identification of equivalent and substitute components necessary for ongoing design support and production continuity. The part operates across a temperature range of -40°C to 85°C with a rated lifetime of 2000 hours at 85°C, suitable for general-purpose applications requiring stable capacitance performance in standard operating conditions.

Substitute Part Grouping Explanation

Substitution of the ECE-V2AA4R7P is determined by strict equivalence in the following core parameters:

• Capacitance Value: 4.7 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting Type: Surface Mount (exact match required)
• Package / Case: Radial, Can - SMD (exact match required)
• Physical Dimensions: 0.315" Dia (8.00mm) and surface mount land size 0.327" L x 0.327" W (8.30mm x 8.30mm) (exact match required)

The substitute parts identified—UUX2D4R7MNL1GS and UUX2E4R7MNL1GS, both manufactured by Nichicon—meet all core equivalence criteria. These substitutes maintain identical capacitance, tolerance, polarization, mounting configuration, and physical footprint. The primary differences are elevated voltage ratings (200 V and 250 V respectively versus 100 V) and improved thermal performance characteristics, which represent functional enhancements rather than deviations from the original specification.

Parameter Comparison

Engineering Selection Recommendations

Both Nichicon substitutes—UUX2D4R7MNL1GS and UUX2E4R7MNL1GS—are active products with ROHS3 compliance and REACH unaffected status, providing regulatory advantages over the obsolete ECE-V2AA4R7P. The Nichicon parts maintain full mechanical and electrical compatibility with the original Panasonic component across all critical substitution parameters.

Selection between the two Nichicon alternatives depends on circuit voltage requirements. The UUX2D4R7MNL1GS (200 V rated) provides adequate margin for applications originally designed for 100 V operation. The UUX2E4R7MNL1GS (250 V rated) offers additional voltage headroom for designs requiring enhanced overvoltage protection or operating in variable supply conditions.

Both substitutes deliver extended thermal performance—3000 hours at 105°C versus 2000 hours at 85°C for the original part—and support expanded operating temperature ranges to 105°C, enabling deployment in higher-temperature environments.

Frequently Asked Questions (FAQ)

Q: Can UUX2D4R7MNL1GS or UUX2E4R7MNL1GS be used as direct replacements for ECE-V2AA4R7P?

A: Yes. Both Nichicon parts maintain identical capacitance (4.7 µF), tolerance (±20%), polarization, mounting type, package configuration, and physical footprint. The elevated voltage ratings represent functional enhancements compatible with 100 V circuit designs.

Q: What is the height difference between the original and substitute parts?

A: The ECE-V2AA4R7P has a maximum seated height of 0.402" (10.20mm), while both Nichicon substitutes measure 0.413" (10.50mm). This 0.011" (0.30mm) difference must be evaluated against PCB clearance constraints and assembly equipment specifications.

Q: Are the Nichicon substitutes RoHS compliant?

A: Yes. Both UUX2D4R7MNL1GS and UUX2E4R7MNL1GS are ROHS3 compliant, whereas the original ECE-V2AA4R7P is RoHS non-compliant. This provides regulatory compliance advantages for new designs and production runs.

Q: How do ripple current ratings compare?

A: The original ECE-V2AA4R7P supports 80 mA ripple current at 120 Hz. Both Nichicon substitutes support 37 mA at 120 Hz and 61.79 mA at 10 kHz. Circuit ripple current requirements must be evaluated against these specifications.

Q: Which substitute should be selected for new designs?

A: Both substitutes are active products with equivalent availability and compliance status. Selection depends on circuit voltage requirements and thermal operating conditions. The UUX2E4R7MNL1GS (250 V) provides maximum voltage margin, while the UUX2D4R7MNL1GS (200 V) offers cost optimization for standard 100 V applications.
