Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UPW1H151MPH is determined by the following critical parameters:

• Electrical Match: Capacitance of 150 µF and voltage rating of 50 V are mandatory requirements
• Tolerance Alignment: ±20% tolerance specification must be maintained
• Temperature Performance: Operating range of -55°C to 105°C must be supported
• Mechanical Compatibility: Through-hole radial configuration with 0.197" (5.00 mm) lead spacing and 0.394" (10.00 mm) case diameter ensures PCB footprint compatibility
• Polarization: Polar configuration is required for circuit function

The EEU-FC1H151 meets all these core substitution criteria, providing electrical and mechanical equivalence despite differences in lifetime rating and physical height.

Parameter Comparison

Engineering Selection Recommendations

The EEU-FC1H151 serves as a direct electrical and mechanical substitute for the UPW1H151MPH. Both components share identical capacitance, voltage rating, tolerance, and temperature operating range. The substitute maintains the same through-hole radial footprint with matching lead spacing and case diameter, ensuring PCB compatibility without layout modifications.

The EEU-FC1H151 is classified as active product status, providing long-term availability and supply chain stability compared to the obsolete UPW1H151MPH. The Panasonic component carries ROHS3 compliance and AEC-Q200 automotive qualification, offering enhanced regulatory alignment for applications requiring these certifications.

Physical height differs between the two components: the substitute is 0.630" (16.00 mm) versus the original 0.492" (12.50 mm). This height differential must be evaluated against available PCB clearance in the target application. The substitute exhibits lower impedance (119 mOhms versus 162 mOhms) and higher ripple current capability at both low and high frequencies, representing improved electrical performance characteristics.

The lifetime rating of the substitute is 3000 hours at 105°C compared to 5000 hours for the original. This difference should be assessed against application duty cycle and thermal operating conditions.

Frequently Asked Questions (FAQ)

Q: Can the EEU-FC1H151 be used as a direct replacement for the UPW1H151MPH?

A: Yes, the EEU-FC1H151 meets all core electrical and mechanical substitution criteria. Both components have identical capacitance (150 µF), voltage rating (50 V), tolerance (±20%), operating temperature range (-55°C to 105°C), and through-hole radial package configuration with matching lead spacing (5.00 mm) and case diameter (10.00 mm). PCB footprint compatibility is maintained without layout changes.

Q: What are the key differences between these two components?

A: The primary differences are product status, compliance certifications, physical height, and performance characteristics. The EEU-FC1H151 is active product with ROHS3 compliance and AEC-Q200 qualification, while the UPW1H151MPH is obsolete and RoHS non-compliant. The substitute is taller (16.00 mm versus 12.50 mm), has lower impedance (119 mOhms versus 162 mOhms), and higher ripple current capability. The original component has a longer lifetime rating (5000 hours versus 3000 hours at 105°C).

Q: Will the increased height of the EEU-FC1H151 cause PCB assembly issues?

A: The 0.138" (4.60 mm) height increase must be verified against available vertical clearance in the target application. If the PCB layout has height constraints, this difference may require design review. Lead spacing and case diameter remain identical, so horizontal footprint compatibility is maintained.

Q: Are there any compliance or certification differences?

A: The EEU-FC1H151 carries ROHS3 compliance and AEC-Q200 automotive qualification. The UPW1H151MPH is RoHS non-compliant. Applications requiring regulatory compliance or automotive qualification should use the Panasonic substitute.

Q: How do the electrical performance characteristics compare?

A: The EEU-FC1H151 demonstrates superior ripple current handling at both 120 Hz (552.5 mA versus 399.75 mA) and 100 kHz (850 mA versus 615 mA). Impedance is lower in the substitute (119 mOhms versus 162 mOhms), indicating better high-frequency performance. These characteristics represent improved electrical capability in the substitute component.

Q: Should lifetime rating differences affect the substitution decision?

A: The lifetime rating difference (3000 hours versus 5000 hours at 105°C) should be evaluated based on application duty cycle and thermal operating conditions. For applications with continuous high-temperature operation, the lower lifetime rating of the substitute may require thermal management review or operational duty cycle assessment.
