Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence in the following parameters: capacitance (150 µF), voltage rating (35 V), tolerance (±20%), polarization (polar), package type (radial can), and mounting type (through hole). All substitute parts maintain these core electrical and mechanical specifications.

Substitute parts are grouped into three categories based on provided specifications:

Category 1: Nichicon Series Variants (UPJ, UPM, UPS) Parts UPJ1V151MPD, UPJ1V151MPD6, UPM1V151MPD, UPM1V151MPD6, and UPS1V151MPD are Nichicon products with identical capacitance, voltage, and tolerance. Variations exist in lifetime ratings (2000–5000 Hrs @ 105°C), lead spacing, height, impedance, and ripple current specifications. UPM series parts carry AEC-Q200 automotive qualification; UPS series offers lower ripple current performance.

Category 2: Panasonic EEU-FC Series Parts EEU-FC1V151, EEU-FC1V151B, and EEU-FC1V151BJ are Panasonic equivalents with active product status and AEC-Q200 automotive ratings. These parts differ in packaging format (bulk, cut tape, tape & box) and lead spacing. All maintain 2000 Hrs @ 105°C lifetime.

Category 3: Chemi-Con LXZ Series Part ELXZ350ELL151MH12D is a Chemi-Con alternative with active product status, AEC-Q200 automotive qualification, and 3000 Hrs @ 105°C lifetime rating.

Engineering Selection Recommendations

For General Purpose Applications: EEU-FC1V151 (Panasonic) or ELXZ350ELL151MH12D (Chemi-Con) are preferred due to active product status. Both provide equivalent electrical performance with established supply availability. EEU-FC1V151 offers the lowest profile (0.492" height) and matches the original impedance specification (117 mOhms).

For Automotive Applications: UPM1V151MPD6 (Nichicon) or EEU-FC1V151B (Panasonic) are suitable selections. UPM1V151MPD6 provides extended 5000 Hrs @ 105°C lifetime with AEC-Q200 qualification. EEU-FC1V151B maintains active product status with automotive certification and compact form factor, though with reduced lifetime (2000 Hrs).

For Space-Constrained Designs: EEU-FC1V151 or EEU-FC1V151BJ (Panasonic) offer the smallest height (0.492") while maintaining electrical equivalence. Both carry AEC-Q200 ratings.

For Extended Lifetime Requirements: UPJ1V151MPD6 or UPM1V151MPD6 (Nichicon) provide 5000 Hrs @ 105°C operation. UPM1V151MPD6 additionally includes AEC-Q200 automotive qualification.

Frequently Asked Questions (FAQ)

Q: Can UPW1V151MPD be directly replaced with EEU-FC1V151? A: Yes. Both parts share identical capacitance (150 µF), voltage rating (35 V), tolerance (±20%), polarization, package type (radial can), and through-hole mounting. EEU-FC1V151 has active product status and lower profile (0.492" vs. 0.453"), making it a direct electrical and mechanical substitute.

Q: What is the difference between EEU-FC1V151 and EEU-FC1V151B? A: The primary difference is lead spacing. EEU-FC1V151 has 0.138" (4.60mm) lead spacing, while EEU-FC1V151B has 0.197" (5.00mm) lead spacing. Both are electrically identical and carry AEC-Q200 automotive qualification. Selection depends on PCB layout requirements.

Q: Why do some substitutes have different heights? A: Height variation reflects different internal construction and lifetime ratings. UPJ1V151MPD (0.630" height) and UPM1V151MPD (0.650" height) accommodate extended internal structure for equivalent performance. Panasonic EEU-FC series maintains compact height (0.492") through optimized design. Verify PCB clearance before selection.

Q: Which substitute offers the best lifetime rating? A: UPJ1V151MPD6 and UPM1V151MPD6 both provide 5000 Hrs @ 105°C operation, compared to the original UPW1V151MPD specification of 3000 Hrs. UPM1V151MPD6 additionally carries AEC-Q200 automotive qualification.

Q: Are all substitutes RoHS3 compliant? A: Yes. All listed substitute parts maintain ROHS3 compliance, matching the original UPW1V151MPD specification.

Q: What does "Not For New Designs" mean for the original part? A: This designation indicates the UPW1V151MPD has been superseded in Nichicon's active product line. While existing inventory remains available, Nichicon recommends using current-generation alternatives for new designs. Active-status substitutes (Panasonic EEU-FC series, Chemi-Con ELXZ series) are preferred for new development.

Q: Can I use UPS1V151MPD as a substitute? A: UPS1V151MPD is electrically equivalent but offers reduced lifetime (2000 Hrs @ 105°C vs. 3000 Hrs) and higher impedance (280 mOhms vs. 117 mOhms). Use only if application requirements permit lower lifetime and higher impedance specifications.
