Engineering Selection Recommendations

For Existing Designs (Maintenance and Repair):

UPW1E151MPD and UPW1V151MPD are direct electrical and mechanical substitutes for the SXR151M016ST. Both Nichicon parts maintain identical capacitance, tolerance, lead spacing, and case diameter specifications. The increased voltage ratings (25 V and 35 V respectively) provide enhanced margin for circuit protection. Both parts are ROHS3 compliant and carry 3000-hour lifetime ratings at 105°C, matching the original specification. Height variations (11.50 mm versus 11.00 mm) remain within acceptable PCB layout tolerances for through-hole applications.

For New Designs:

EEU-FM1V151 is the recommended choice for new applications. This Panasonic part carries Active product status, ensuring long-term availability and supply chain stability. The EEU-FM1V151 maintains all critical electrical and mechanical parameters while offering superior performance characteristics: lower impedance (56 mOhms versus 117 mOhms in Nichicon parts), higher ripple current capability (665 mA @ 120 Hz and 950 mA @ 100 kHz), and extended operating temperature range (-40°C to 105°C). ROHS3 compliance and REACH Unaffected status confirm regulatory alignment for current manufacturing standards.

All three substitute parts are electrically and mechanically compatible with the SXR151M016ST within the specified parameter allowances.

Frequently Asked Questions (FAQ)

Q: Can UPW1E151MPD or UPW1V151MPD be used as direct replacements for SXR151M016ST?

A: Yes. Both Nichicon parts meet all mandatory matching parameters: 150 µF capacitance, ±20% tolerance, 0.138" lead spacing, 0.315" case diameter, through-hole mounting, and radial can package. The higher voltage ratings (25 V and 35 V) are allowable variations that do not compromise circuit compatibility.

Q: Why is EEU-FM1V151 recommended for new designs?

A: EEU-FM1V151 carries Active product status, ensuring continued manufacturing and availability. The part meets all electrical and mechanical requirements while providing superior performance: lower impedance, higher ripple current ratings, and extended temperature range. ROHS3 compliance and REACH Unaffected status align with current regulatory requirements.

Q: What is the significance of the height difference between SXR151M016ST (11.00 mm) and substitute parts (11.50 mm or 13.00 mm)?

A: The height variations are within acceptable tolerances for through-hole PCB applications. Designers must verify clearance in their specific board layout, particularly in space-constrained applications. The increased height does not affect electrical performance or lead spacing compatibility.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. SXR151M016ST, UPW1E151MPD, UPW1V151MPD, and EEU-FM1V151 are all ROHS3 compliant, meeting current environmental and regulatory standards.

Q: What is the difference between "Not For New Designs" and "Active" product status?

A: "Not For New Designs" indicates the manufacturer is phasing out the product; existing inventory may be available but future supply is not guaranteed. "Active" status confirms the manufacturer continues production and supports long-term availability. For new designs, Active-status parts provide supply chain certainty.

Q: Can these substitutes be used interchangeably in the same circuit?

A: Yes, within the specified parameter allowances. All substitute parts maintain the same capacitance, tolerance, voltage rating compatibility, lead spacing, and case diameter. Circuit designers must verify that the higher voltage ratings and performance characteristics of substitute parts do not introduce unintended effects in their specific application.
