UST1C470MDD Equivalent & Substitute Parts

Part Overview

The UST1C470MDD is a 47 µF, 16 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, with 1000 hours lifetime rating at 105°C. Due to its obsolete status, equivalent and substitute parts from active product lines or alternative manufacturers are necessary for ongoing design support and procurement continuity.

Substitute Part Grouping Explanation

Substitution eligibility for the UST1C470MDD is determined by the following critical parameters:

Capacitance: 47 µF (exact match required)
Voltage Rating: 16 V minimum (equal or higher acceptable)
Tolerance: ±20% (matching or tighter tolerance acceptable)
Package Type: Radial, Can (physical form factor)
Mounting Type: Through Hole (PCB assembly compatibility)
Operating Temperature Range: -55°C ~ 105°C (minimum requirement)
Polarization: Polar (electrical characteristic)
RoHS Compliance: ROHS3 Compliant (regulatory requirement)

Substitutes are grouped into three categories:

Nichicon Series Equivalents (UPJ1C470MDD, UPM1C470MDD, UPS1C470MDD, UPV1C470MFD): Same manufacturer, same capacitance and voltage, with improved lifetime ratings (2000–5000 hours) and enhanced ripple current handling.
Nichicon Higher Voltage Alternative (UVZ1H470MED): Same manufacturer and capacitance, rated for 50 V (higher voltage rating), suitable where voltage margin is required.
Nichicon Surface Mount Option (UWT1C470MCL1GB): Active product with SMD package, same electrical specifications but different mounting technology.
Panasonic Equivalents (EEA-GA1C470, ECA-1CHG470, EEA-GA1C470B, EEA-GA1C470H): Alternative manufacturer with matching capacitance, voltage, and tolerance. All are active products with ROHS3 compliance.

Engineering Selection Recommendations

Direct Replacement (Same Form Factor)

EEA-GA1C470H (Panasonic) and EEA-GA1C470 (Panasonic) are the preferred direct replacements. Both match the original lead spacing (0.098", 2.50mm) and diameter (0.248", 6.30mm), with active product status ensuring long-term availability. Both are ROHS3 compliant and rated for 1000 hours at 105°C, matching the original specification.

Nichicon Alternatives with Improved Lifetime

UPJ1C470MDD, UPM1C470MDD, and UPS1C470MDD offer extended lifetime ratings (2000 hours) while maintaining 16 V rating and ±20% tolerance. These parts feature reduced lead spacing (0.079", 2.00mm) and smaller diameter (0.197", 5.00mm), requiring PCB layout verification before substitution.

Extended Lifetime Option

UPV1C470MFD (Nichicon) provides 5000-hour lifetime at 105°C with the same electrical specifications. Physical dimensions match the UPJ/UPM/UPS series, requiring layout confirmation.

Higher Voltage Margin

UVZ1H470MED (Nichicon) is rated for 50 V, providing additional voltage margin in applications where circuit voltage may exceed 16 V. Physical dimensions match the original part (0.248" diameter, 0.098" lead spacing).

Surface Mount Alternative

UWT1C470MCL1GB (Nichicon) is an active SMD variant with identical electrical specifications. This option applies only to new designs or rework scenarios where SMD assembly is feasible.

Alternative Manufacturer Options

ECA-1CHG470 (Panasonic, active status) and EEA-GA1C470B (Panasonic, active status) provide equivalent electrical performance with different lead spacing configurations. Lead spacing verification is required before PCB substitution.

Frequently Asked Questions (FAQ)

Q: Can I substitute UPJ1C470MDD for UST1C470MDD directly on the PCB?

A: Electrical substitution is valid (same capacitance, voltage, tolerance, and temperature range). However, physical dimensions differ: UPJ1C470MDD has 0.079" lead spacing versus the original 0.098" spacing. PCB hole pattern verification is required before installation.

Q: What is the difference between Nichicon UPJ, UPM, and UPS series?

A: All three series share identical electrical specifications (47 µF, 16 V, ±20%, 2000-hour lifetime). Differences exist in ripple current handling and impedance characteristics. UPS1C470MDD offers the highest ripple current at high frequency (160 mA @ 100 kHz). Series selection depends on application ripple current requirements.

Q: Is UVZ1H470MED a suitable replacement?

A: UVZ1H470MED is electrically compatible (47 µF, ±20%, same temperature range) but rated for 50 V instead of 16 V. This higher voltage rating is acceptable for direct substitution and provides additional safety margin. Physical dimensions match the original part. Use this option when voltage margin is beneficial.

Q: Why is UWT1C470MCL1GB listed as an alternative if it is surface mount?

A: UWT1C470MCL1GB is included for reference in new design scenarios or PCB rework where SMD assembly is available. It is not suitable for through-hole PCB replacement without significant rework.

Q: Are Panasonic EEA-GA1C470 and EEA-GA1C470H interchangeable?

A: Both are Panasonic GA-A series with identical electrical specifications and active product status. The primary difference is lead spacing: EEA-GA1C470H uses 0.098" (2.50mm) spacing matching the original UST1C470MDD, while EEA-GA1C470 uses the same spacing. Both are suitable direct replacements with PCB hole pattern verification.

Q: What does "active product status" mean for component selection?

A: Active status indicates the manufacturer currently produces and supports the part, ensuring long-term availability and consistent supply. Obsolete parts like UST1C470MDD are no longer manufactured, making active alternatives necessary for production continuity.

Q: Can I use a 47 µF capacitor with different tolerance (e.g., ±10%)?

A: Tighter tolerance (±10%) is acceptable as a substitute for ±20%. Looser tolerance is not recommended without circuit analysis, as it may exceed design specifications.

Q: What is the significance of lead spacing differences?

A: Lead spacing determines PCB hole pattern compatibility. Original 0.098" (2.50mm) spacing requires matching hole spacing. Alternatives with 0.079" (2.00mm) spacing require PCB modification or cannot be installed without rework.
