Voltage Rating: 35 V
Tolerance: ±20%
Polarization: Polar

Mechanical Parameters (Must Match):

Package Type: Radial, Can
Mounting Type: Through Hole
Size / Dimension: 0.315" Dia (8.00mm)
Operating Temperature Range: -40°C ~ 105°C

Secondary Considerations:

Lead Spacing: 0.138" (4.60mm) preferred for direct PCB compatibility
Height: 0.512" (13.00mm) or 0.492" (12.50mm) acceptable within mechanical envelope
Lifetime @ Temperature: Higher ratings provide extended service life
ESR and Ripple Current: Performance characteristics that may vary between manufacturers

Parts are grouped as Upgrade (improved specifications) or Similar (equivalent functionality with packaging variations).

Engineering Selection Recommendations

Upgrade Options (Improved Specifications):

The 157KBM035M (Cornell Dubilier / Illinois Capacitor) and 35YXH150MEFC8X11.5 (Rubycon) both offer extended lifetime ratings of 7000 hours at 105°C compared to the original 6000 hours. Both maintain identical electrical specifications and mechanical compatibility with 0.138" (4.60mm) lead spacing. The 157KBM035M is currently Active, while the 35YXH150MEFC8X11.5 is Last Time Buy status. Both are ROHS3 compliant.

Direct Equivalents (Identical Mechanical Fit):

The EEU-FM1V151 (Panasonic Electronic Components) provides direct PCB compatibility with 0.138" (4.60mm) lead spacing and identical physical dimensions. This part is Active status and ROHS3 compliant. The EKZE350ELL151MHB5D (Chemi-Con) also maintains the original lead spacing and dimensions, with Active status and ROHS3 compliance.

Alternative with Lead Spacing Variation:

The EEU-FM1V151B and EEU-FM1V151BJ (Panasonic Electronic Components) feature 0.197" (5.00mm) lead spacing instead of 0.138" (4.60mm). These require PCB modification or adapter consideration but are available in higher quantities and remain Active. Both are ROHS3 compliant.

Compliance Considerations:

All substitute parts listed are ROHS3 compliant, matching the original component's regulatory status. Selection should prioritize parts with Active product status for long-term availability and supply chain stability.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with different lead spacing?

A: Lead spacing differences require PCB layout verification. The original UHV1V151MPD uses 0.138" (4.60mm) spacing. Parts with 0.197" (5.00mm) spacing (EEU-FM1V151B, EEU-FM1V151BJ) will not fit standard PCB holes without modification. Direct replacements maintain 0.138" (4.60mm) spacing.

Q: What is the difference between Upgrade and Similar classifications?

A: Upgrade parts (157KBM035M, 35YXH150MEFC8X11.5) offer improved lifetime ratings (7000 hours vs. 6000 hours) while maintaining all electrical and mechanical specifications. Similar parts provide equivalent functionality with variations in lead spacing, packaging format, or lifetime ratings.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed in this reference maintain ROHS3 compliance, matching the original UHV1V151MPD specification.

Q: Which substitute offers the best availability?

A: The EEU-FM1V151B and EEU-FM1V151BJ (Panasonic) show higher inventory levels and Active product status. However, lead spacing differs at 0.197" (5.00mm). For direct PCB compatibility with original spacing, the 157KBM035M and EEU-FM1V151 are recommended.

Q: Can I substitute based on capacitance and voltage alone?

A: No. Mechanical parameters including lead spacing, package dimensions, and height must match or be verified for PCB compatibility. The 0.138" (4.60mm) lead spacing of the original part is critical for direct replacement without layout modification.

Q: What does "Last Time Buy" status mean?

A: Last Time Buy indicates the manufacturer will discontinue production after a specified date. The 35YXH150MEFC8X11.5 (Rubycon) carries this status, meaning current inventory represents the final available stock. Active status parts are recommended for new procurement.
