Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the EEE-2AA4R7P is determined by 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)
• Operating temperature range: -40°C ~ 85°C (minimum requirement)
• Lifetime specification: 2000 Hrs @ 85°C (minimum requirement)
• RoHS compliance: ROHS3 Compliant (required for regulatory alignment)
• MSL rating: 1 (Unlimited) (required for handling compatibility)

The substitute part UUR2A4R7MCL1GS from Nichicon meets all critical electrical and mechanical parameters. Both parts share identical capacitance, voltage rating, tolerance, package configuration, and surface mount land size (0.327" L x 0.327" W). Both maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory and handling compatibility.

Parameter Comparison

Engineering Selection Recommendations

The UUR2A4R7MCL1GS qualifies as a direct electrical and mechanical substitute for the EEE-2AA4R7P based on matching capacitance, voltage rating, tolerance, package configuration, and surface mount land pattern. Both parts maintain identical RoHS3 compliance and MSL 1 ratings, ensuring regulatory and handling compatibility.

The primary design consideration is the height difference: the Panasonic part measures 0.402" (10.20mm) seated height, while the Nichicon substitute measures 0.256" (6.50mm). This dimensional variance requires verification against PCB layout constraints and clearance requirements in the target application. The reduced height of the Nichicon part may provide design flexibility in space-constrained applications.

Both parts are rated for automotive applications with equivalent thermal and electrical performance specifications. Selection between these parts should be based on available inventory, procurement lead times, and physical clearance validation for the specific PCB assembly.

Frequently Asked Questions (FAQ)

Q: Can UUR2A4R7MCL1GS replace EEE-2AA4R7P in automotive applications?

A: Yes. Both parts meet identical electrical specifications (4.7 µF, 100 V, ±20% tolerance) and maintain ROHS3 compliance. The Nichicon part is suitable for general purpose applications and meets the same operating temperature range and lifetime requirements. Physical clearance must be confirmed due to the height difference.

Q: What is the primary difference between these two parts?

A: The seated height differs: EEE-2AA4R7P is 0.402" (10.20mm) while UUR2A4R7MCL1GS is 0.256" (6.50mm). All other electrical and mechanical parameters, including capacitance, voltage rating, package type, and land pattern, are identical.

Q: Are both parts RoHS compliant?

A: Yes. Both EEE-2AA4R7P and UUR2A4R7MCL1GS are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What packaging formats are available for the substitute part?

A: The UUR2A4R7MCL1GS is supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: Do these parts have identical ripple current ratings?

A: No. The EEE-2AA4R7P is rated for 80 mA @ 120 Hz and 136 mA @ 10 kHz. The UUR2A4R7MCL1GS is rated for 40 mA @ 120 Hz and 66.8 mA @ 10 kHz. Applications requiring higher ripple current handling should retain the original Panasonic part or identify alternative substitutes with matching ripple current specifications.
