Engineering Selection Recommendations

The EEU-FC1A151 is the primary specification part with active production status and AEC-Q200 automotive qualification. Both substitute parts are classified as obsolete.

UPW1A151MED offers a 2000-hour lifetime rating at 105°C, which exceeds the primary part's 1000-hour specification. This part maintains equivalent ripple current ratings and lower impedance (250 mOhms versus 350 mOhms), providing improved high-frequency performance characteristics. Height is reduced to 0.433" (11.00 mm), which may be advantageous in space-constrained applications.

UPV1A151MGD provides the highest lifetime rating at 5000 hours at 105°C. However, this part exhibits higher impedance (600 mOhms) and increased height (0.492" or 12.50 mm). Ripple current specifications are not provided for this part.

Both substitute parts maintain ROHS3 compliance and REACH unaffected status, matching the primary part's regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can UPV1A151MGD and UPW1A151MED be used interchangeably with EEU-FC1A151?

A: Yes, both parts meet all electrical and mechanical substitution criteria. All three parts share identical capacitance (150 µF), voltage rating (10 V), tolerance (±20%), lead spacing (0.098" or 2.50 mm), diameter (0.248" or 6.30 mm), and operating temperature range (-55°C to 105°C). Physical height differences are minor and typically do not affect PCB layout compatibility in standard through-hole applications.

Q: What are the differences in lifetime ratings?

A: The EEU-FC1A151 is rated for 1000 hours at 105°C. The UPW1A151MED extends this to 2000 hours, while the UPV1A151MGD provides 5000 hours at the same temperature. Selection depends on application duty cycle and expected operational life requirements.

Q: How do impedance differences affect circuit performance?

A: The three parts exhibit different impedance values: EEU-FC1A151 at 350 mOhms, UPW1A151MED at 250 mOhms, and UPV1A151MGD at 600 mOhms. Lower impedance generally provides better high-frequency filtering characteristics. The UPW1A151MED offers the lowest impedance, while the UPV1A151MGD exhibits higher impedance that may affect ripple filtering performance in high-frequency applications.

Q: Are there height constraints I should consider?

A: Physical heights differ slightly: EEU-FC1A151 at 0.480" (12.20 mm), UPW1A151MED at 0.433" (11.00 mm), and UPV1A151MGD at 0.492" (12.50 mm). In space-constrained PCB designs, the UPW1A151MED provides a compact option. The UPV1A151MGD is marginally taller and may require clearance verification in confined mounting areas.

Q: What is the significance of product status classifications?

A: The EEU-FC1A151 maintains active production status, ensuring continued availability and supply chain stability. Both substitute parts are classified as obsolete, indicating discontinued production. Obsolete parts may have limited inventory availability and extended lead times. Selection of obsolete substitutes should be based on specific application requirements that justify the supply chain risk.

Q: Are all parts automotive-qualified?

A: The EEU-FC1A151 carries AEC-Q200 automotive qualification. The substitute parts do not list automotive ratings in the provided specifications. Applications requiring automotive qualification should prioritize the EEU-FC1A151 or verify automotive compliance documentation for substitute parts independently.
