ECE-V2AA4R7UP Equivalent & Substitute Parts

Part Overview

The ECE-V2AA4R7UP is a 4.7 µF, 100 V aluminum electrolytic capacitor in surface mount radial can package manufactured by Panasonic Electronic Components. This component is rated for 2000 hours at 85°C operation and is designed for general purpose applications requiring polar capacitance in compact SMD form factor.

The ECE-V2AA4R7UP carries an obsolete product status. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support ongoing production or repair requirements for systems utilizing this component.

Substitute Part Grouping Explanation

Substitution eligibility for the ECE-V2AA4R7UP is determined by strict equivalence across the following critical parameters:

• Capacitance value: 4.7 µF (exact match required)
• Voltage rating: 100 V (exact match required)
• Tolerance: ±20% (exact match required)
• Package type: Radial, Can - SMD (exact match required)
• Mounting type: Surface Mount (exact match required)
• Polarization: Polar (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 part UUX2A4R7MCL1GS manufactured by Nichicon meets all critical substitution criteria. This part maintains identical electrical specifications (capacitance, voltage, tolerance) and physical compatibility (package, mounting type, land size) with the original ECE-V2AA4R7UP.

Parameter Comparison

Engineering Selection Recommendations

The UUX2A4R7MCL1GS is a direct functional substitute for the ECE-V2AA4R7UP based on electrical and mechanical parameter equivalence. The substitute part offers the following advantages:

• Active product status ensures ongoing availability and supply chain support
• ROHS3 compliance meets current regulatory requirements, whereas the original part is RoHS non-compliant
• Extended operating temperature range (-55°C ~ 105°C) provides broader thermal operational envelope compared to the original (-40°C ~ 85°C)
• Higher temperature lifetime rating (2000 Hrs @ 105°C) demonstrates enhanced thermal performance

The substitute part exhibits a marginal height difference of 0.012" (0.30mm) in seated height. This dimension must be evaluated against specific PCB layout and clearance constraints in the target application. The ripple current specification at 120 Hz is 42 mA for the substitute versus 50 mA for the original; this parameter must be verified against circuit ripple current requirements.

Frequently Asked Questions (FAQ)

Q: Can the UUX2A4R7MCL1GS replace the ECE-V2AA4R7UP in existing designs?

A: Yes, the UUX2A4R7MCL1GS is electrically and mechanically equivalent. Both parts share identical capacitance (4.7 µF), voltage rating (100 V), tolerance (±20%), package type (Radial, Can - SMD), and surface mount land size (0.327" L x 0.327" W). The substitute part is pin-compatible and footprint-compatible with the original.

Q: What is the height difference between these parts?

A: The ECE-V2AA4R7UP has a maximum seated height of 0.244" (6.20mm), while the UUX2A4R7MCL1GS has a maximum seated height of 0.256" (6.50mm). The difference is 0.012" (0.30mm). Verify that this height increase does not conflict with PCB clearance requirements or component placement constraints in your specific application.

Q: Are there differences in ripple current ratings?

A: Yes. The ECE-V2AA4R7UP is rated for 50 mA ripple current at 120 Hz. The UUX2A4R7MCL1GS is rated for 42 mA at 120 Hz and 70.14 mA at 10 kHz. Confirm that the substitute part's ripple current specification meets the actual ripple current demands of your circuit.

Q: What are the compliance differences?

A: The ECE-V2AA4R7UP is RoHS non-compliant. The UUX2A4R7MCL1GS is ROHS3 compliant and REACH unaffected. If your application or market requires RoHS compliance, the substitute part satisfies these regulatory requirements.

Q: Why is the original part obsolete?

A: The ECE-V2AA4R7UP carries an obsolete product status from Panasonic. The UUX2A4R7MCL1GS is an active product from Nichicon with confirmed inventory availability (26203 pcs in stock), ensuring reliable supply for current and future production needs.
