Substitute Part Grouping Explanation

Substitution for the EEE-1VA470WP is determined by strict equivalence in the following parameters: capacitance (47 µF), voltage rating (35 V), tolerance (±20%), package type (Radial, Can - SMD), and surface mount land size (0.260" L x 0.260" W / 6.60mm x 6.60mm). Physical dimensions, operating temperature range, lifetime rating, and compliance certifications are secondary considerations that determine suitability for specific applications.

Substitute parts are grouped into four categories:

MFR Recommended: Active production parts from the original manufacturer with improved performance characteristics (extended lifetime, lower ESR, higher ripple current capability).

Upgrade: Active production parts offering superior electrical performance while maintaining full parameter compatibility.

Similar: Parts from the original manufacturer with identical electrical specifications but different physical dimensions or product status.

Direct: Functionally equivalent parts from alternative manufacturers meeting the core electrical and mechanical requirements.

Engineering Selection Recommendations

For Direct Replacement (Same PCB Layout): EEE-1VA470WAP is the primary choice. It maintains identical physical dimensions (0.248" diameter, 0.213" height) and land size (0.260" x 0.260") as the EEE-1VA470WP while offering Active product status and ROHS3 compliance. Electrical performance is equivalent with 1000 hours lifetime at 85°C.

For Enhanced Performance: EEE-FP1V470AP provides superior electrical characteristics with extended lifetime (2000 hours at 105°C), lower ESR (260 mOhm @ 100kHz), and higher ripple current capability (300 mA @ 100 kHz). Physical dimensions are compatible with the original footprint. This part is recommended for new designs requiring improved reliability margins.

For Extended Temperature Range: EEE-FN1V470P, 476AXZ035MQ5, EEV476M035A9GAA, EMVY350ARA470MF55G, and UCL1V470MCL1GS all support -55°C to 105°C operation with 2000-hour lifetimes at 105°C. These parts are suitable for applications requiring wider operating temperature specifications.

For Alternative Manufacturers: KEMET (EDK476M035A9GAA, EEV476M035A9GAA), Cornell Dubilier (476AXZ035MQ5), Chemi-Con (EMVY350ARA470MF55G), and Nichicon (UCL1V470MCL1GS) provide functionally equivalent alternatives. All maintain the required 47 µF / 35 V specifications, surface mount package, and ROHS3 compliance.

Compatibility Constraints: Parts EEE-1VA470AP and EEE-1VA470P have larger physical dimensions (0.315" diameter, 0.327" x 0.327" land size) and require PCB layout modifications. These are suitable only when board space permits the larger footprint.

Frequently Asked Questions (FAQ)

Q: Can EEE-FP1V470AP replace EEE-1VA470WP without PCB modifications?

A: Yes. Both parts share identical physical dimensions (0.248" diameter) and surface mount land size (0.260" x 0.260"). The EEE-FP1V470AP height is 0.228" compared to 0.213" for the original, a difference of 0.015" that does not affect PCB assembly or clearance in standard designs.

Q: What is the primary difference between MFR Recommended and Upgrade categories?

A: MFR Recommended parts (EEE-FN1V470P) are direct successors from Panasonic with improved lifetime and temperature range. Upgrade parts (EEE-FP1V470AP) offer additional performance enhancements including lower ESR and higher ripple current ratings while maintaining full electrical compatibility.

Q: Are parts with larger physical dimensions (EEE-1VA470AP, EEE-1VA470P) suitable for existing designs?

A: These parts require PCB layout verification. The 0.315" diameter and 0.327" x 0.327" land size are larger than the original 0.248" diameter and 0.260" x 0.260" land size. Use only if board space and component placement allow the larger footprint.

Q: Which substitute parts support automotive applications?

A: EEE-FN1V470P and EEE-FP1V470AP carry AEC-Q200 automotive qualification. Alternative manufacturer parts (KEMET, Cornell Dubilier, Chemi-Con, Nichicon) do not list automotive ratings but are suitable for general purpose applications.

Q: What is the impact of different lifetime ratings on part selection?

A: Lifetime rating indicates capacitor reliability under specified temperature conditions. The original EEE-1VA470WP provides 1000 hours at 85°C. Substitute parts offering 2000 hours at 105°C provide extended operational life and are recommended for applications requiring higher reliability margins or operation at elevated temperatures.

Q: Are all substitute parts RoHS3 compliant?

A: All listed substitute parts carry ROHS3 compliance. The original EEE-1VA470WP is RoHS Compliant (ROHS2). ROHS3 represents current compliance standards and is preferred for new designs.

Q: Can parts with different ESR values be interchanged?

A: ESR differences affect ripple current handling and thermal performance. Parts with lower ESR (EEE-FP1V470AP at 260 mOhm, UCL1V470MCL1GS at 260 mOhm) provide better high-frequency performance. Verify ripple current requirements in your application before substitution.
