Voltage Rating: 10 V (exact match required)
Tolerance: ±20% (exact match required)
Lifetime @ Temperature: 2000 Hrs @ 85°C (exact match required)
Operating Temperature Range: -40°C ~ 85°C (exact match required)
Lead Spacing: 0.197" (5.00 mm) (exact match required)
Case Diameter: 0.492" (12.50 mm) (exact match required)
Mounting Type: Through Hole (exact match required)

Engineering Selection Recommendations

Direct Equivalent (Nichicon UVR1A472MHD): This part maintains identical electrical specifications and lead spacing as the original UVR1A472MHA. The primary difference is increased height (27.00 mm vs. 25.00 mm) and ROHS3 compliance. This substitution is suitable for applications where PCB clearance permits the additional height. Product status is "Not For New Designs," indicating limited future availability.

Form Factor Match (Nichicon UFW1A472MHD and UKW1A472MHD): Both parts preserve the original height of 0.984" (25.00 mm), making them optimal for space-constrained designs. Both are ROHS3 compliant and maintain all core electrical parameters. These parts are designated for audio applications but are electrically compatible with general-purpose use. Product status is "Not For New Designs."

Active Alternative (Panasonic ECA-1AM472): This part is the only substitute with Active product status, ensuring continued availability and supply chain stability. It is ROHS3 compliant and meets all electrical specifications. Height is 1.063" (27.00 mm), requiring verification of PCB clearance. This option is recommended for new designs or long-term production requirements.

Frequently Asked Questions (FAQ)

Q: Can UVR1A472MHD be used as a direct replacement for UVR1A472MHA?

A: Yes. Both parts share identical capacitance (4700 µF), voltage rating (10 V), tolerance (±20%), lifetime (2000 Hrs @ 85°C), operating temperature range (-40°C ~ 85°C), lead spacing (5.00 mm), and case diameter (12.50 mm). The primary difference is height: UVR1A472MHD measures 27.00 mm versus 25.00 mm for the original. Verify PCB clearance before substitution.

Q: What is the difference between UFW1A472MHD and UKW1A472MHD?

A: Both parts are electrically identical and maintain the original height of 25.00 mm. The primary distinction is the series designation (UFW vs. UKW), which reflects internal design variations within Nichicon's product line. Both are suitable for the same applications and have identical electrical performance.

Q: Why is ECA-1AM472 recommended for new designs?

A: ECA-1AM472 is the only substitute with Active product status, ensuring long-term availability and supply chain continuity. It is manufactured by Panasonic Electronic Components and meets all electrical specifications of the original part. For applications requiring sustained production or future component sourcing, this part provides the greatest reliability.

Q: Are there height restrictions when substituting these parts?

A: Yes. The original UVR1A472MHA has a maximum seated height of 25.00 mm. Substitutes UVR1A472MHD and ECA-1AM472 measure 27.00 mm, requiring 2.00 mm additional clearance. UFW1A472MHD and UKW1A472MHD maintain the original 25.00 mm height and are preferred for space-constrained applications.

Q: Do all substitutes meet current RoHS compliance requirements?

A: The original UVR1A472MHA is RoHS non-compliant. All identified substitutes (UVR1A472MHD, UFW1A472MHD, UKW1A472MHD, and ECA-1AM472) are ROHS3 compliant, meeting current environmental and regulatory standards.

Q: What ripple current specifications should I verify?

A: All substitutes maintain the same ripple current ratings as the original: 1.8 A @ 120 Hz and 2.07 A @ 10 kHz. These specifications are consistent across all equivalent parts and do not require re-evaluation during substitution.
