Key Parameters

Substitute Part Grouping Explanation

Substitution of the UTT1H470MPD is determined by the following critical parameters:

• Capacitance Value: 47 µF (exact match required)
• Tolerance: ±20% (standard tolerance maintained)
• Voltage Rating: Minimum 50 V (equal or higher voltage rating acceptable)
• Package Type: Radial, Can configuration (mechanical compatibility)
• Lead Spacing: 0.138" (4.60 mm) (PCB footprint compatibility)
• Mounting Type: Through Hole (assembly process compatibility)
• RoHS Compliance: ROHS3 Compliant (regulatory requirement)

The identified substitute, Nichicon UPW1J470MPD, meets all critical substitution criteria. The UPW1J470MPD provides a higher voltage rating (63 V versus 50 V), which is acceptable for direct substitution in applications designed for the 50 V rated component. Physical dimensions and lead spacing remain compatible with existing PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

The Nichicon UPW1J470MPD serves as the direct functional equivalent for the obsolete UTT1H470MPD. Both components maintain ROHS3 compliance and are manufactured by Nichicon, ensuring consistent quality and reliability standards.

The UPW1J470MPD provides superior electrical performance characteristics, including lower impedance (342 mOhms versus 1.4 Ohms) and higher ripple current handling capacity at both low frequency (121.5 mA @ 120 Hz) and high frequency (405 mA @ 100 kHz) conditions. The elevated voltage rating (63 V) provides additional design margin for applications originally specified at 50 V.

Physical compatibility is maintained across lead spacing and radial can package configuration. The increased seated height (0.453" versus 0.354") requires verification against PCB clearance constraints in the target application. The extended operating temperature range (-55°C to 105°C versus -40°C to 105°C) accommodates broader environmental conditions.

Frequently Asked Questions (FAQ)

Q: Can the UPW1J470MPD directly replace the UTT1H470MPD on existing PCBs?

A: Yes, for applications where PCB clearance permits the increased height of 0.453" (11.50 mm). Lead spacing and radial can package dimensions are identical, ensuring footprint compatibility.

Q: Is the higher voltage rating (63 V) of the UPW1J470MPD acceptable for a 50 V application?

A: Yes. A higher voltage rating does not degrade performance in lower voltage applications. The component will operate safely and reliably at voltages up to and including its rated maximum.

Q: What is the impact of the lower impedance in the UPW1J470MPD?

A: Lower impedance (342 mOhms versus 1.4 Ohms) indicates improved high-frequency performance and reduced voltage ripple, which is beneficial for most general purpose applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the UTT1H470MPD and UPW1J470MPD are ROHS3 compliant, meeting current regulatory requirements for electronic component manufacturing and use.

Q: What is the significance of the product status difference?

A: The UTT1H470MPD is classified as obsolete and no longer manufactured. The UPW1J470MPD is classified as "Not For New Designs," indicating limited availability but continued support for existing applications. For new designs, consultation with Nichicon regarding current production alternatives is recommended.
