Key Parameters

Substitute Part Grouping Explanation

Substitution of the obsolete UPB1H471MHD1TO is determined by strict equivalence across the following critical parameters:

• Capacitance value: 470 µF (exact match required)
• Voltage rating: 50 V (exact match required)
• Tolerance: ±20% (exact match required)
• Polarization: Polar (exact match required)
• Mounting type: Through Hole (exact match required)
• Package type: Radial, Can (exact match required)
• Lead spacing: 0.197" (5.00 mm) (exact match required)
• Physical dimensions: 0.492" Dia (12.50 mm) (exact match required)
• Operating temperature range: -40°C ~ 105°C (exact match required)
• Ripple current specifications: 370 mA @ 120 Hz and 481 mA @ 100 kHz (exact match required)

The EEU-EB1H471 manufactured by Panasonic Electronic Components meets all these criteria and qualifies as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The EEU-EB1H471 is the qualified substitute for the obsolete UPB1H471MHD1TO. Selection is based on the following factors:

• All critical electrical parameters match exactly: capacitance, voltage rating, tolerance, ripple current specifications, and operating temperature range.
• Physical dimensions and lead spacing are identical, ensuring direct mechanical compatibility with existing PCB layouts.
• The substitute part is currently in active production status, providing long-term availability and supply chain stability.
• The EEU-EB1H471 carries ROHS3 compliance and REACH unaffected status, meeting modern regulatory requirements.
• The substitute offers improved lifetime specification (10000 hours at 105°C versus 7000 hours), providing enhanced reliability margin.
• Height difference of 0.020" (0.50 mm) is within typical PCB clearance tolerances and does not impact functional performance.

Frequently Asked Questions (FAQ)

Q: Can the EEU-EB1H471 be used as a direct replacement for the UPB1H471MHD1TO?

A: Yes. The EEU-EB1H471 meets all critical electrical and mechanical specifications required for direct substitution, including capacitance, voltage rating, tolerance, ripple current, operating temperature range, lead spacing, and physical dimensions.

Q: What is the difference in height between these two parts?

A: The UPB1H471MHD1TO has a maximum seated height of 0.846" (21.50 mm), while the EEU-EB1H471 has a maximum seated height of 0.866" (22.00 mm). The difference of 0.020" (0.50 mm) is within standard PCB clearance tolerances and does not affect circuit performance or board layout compatibility.

Q: Why is the substitute part rated for longer lifetime?

A: The EEU-EB1H471 specifies 10000 hours at 105°C compared to 7000 hours for the original part. This represents an improvement in the capacitor's thermal endurance specification and provides additional reliability margin in applications operating at elevated temperatures.

Q: Are there any compliance or regulatory differences?

A: The EEU-EB1H471 carries ROHS3 compliance and REACH unaffected status. Both parts are classified under the same HTSUS code (8532.22.0020) and ECCN (EAR99).

Q: What is the lead spacing for these capacitors?

A: Both the UPB1H471MHD1TO and EEU-EB1H471 have a lead spacing of 0.197" (5.00 mm), ensuring compatibility with existing through-hole PCB footprints.

Q: Are the ripple current ratings identical?

A: Yes. Both parts are rated for 370 mA at 120 Hz and 481 mA at 100 kHz, ensuring equivalent performance in AC ripple current applications.
