UPW2C470MHD Equivalent & Substitute Parts

Part Overview

The UPW2C470MHD is a 47 µF, 160 V aluminum electrolytic capacitor in radial, can package manufactured by Nichicon. This component is classified as obsolete, with a rated lifetime of 7000 hours at 105°C. Due to its obsolete status, equivalent and substitute parts from active product lines or alternative manufacturers are necessary for new designs and ongoing production requirements. Substitute parts maintain the same capacitance and voltage rating while offering improved specifications such as extended lifetime, enhanced ripple current handling, or better availability.

Substitute Part Grouping Explanation

Substitution for the UPW2C470MHD is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

Capacitance: 47 µF (exact match required)
Voltage Rating: 160 V minimum (equal or higher acceptable)
Tolerance: ±20% (exact match required)
Polarization: Polar (exact match required)
Operating Temperature: -40°C ~ 105°C (exact match required)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)

Secondary Compatibility Factors:

Lead Spacing: 0.197" (5.00mm) preferred for direct PCB compatibility
Diameter and Height: Physical dimensions must accommodate board layout constraints
Lifetime @ 105°C: Extended lifetime acceptable; reduced lifetime not acceptable
Ripple Current: Higher ripple current capability acceptable; lower capability requires application verification

Substitute parts are grouped into three categories: MFR Recommended (active product with enhanced specifications), Upgrade (higher voltage rating within same series), and Similar (equivalent electrical performance with varying physical or lifetime characteristics).

Engineering Selection Recommendations

MFR Recommended Substitute: UCS2E470MHD

The UCS2E470MHD is the primary recommended substitute. It is manufactured by Nichicon and carries Active product status. This part offers a higher voltage rating of 250 V, which provides additional design margin beyond the original 160 V specification. The lifetime rating of 10000 hours at 105°C exceeds the original 7000 hours, improving long-term reliability. The lead spacing and diameter remain identical at 0.197" (5.00mm) and 0.492" (12.50mm), ensuring direct PCB compatibility. Height is reduced to 0.846" (21.50mm), which may provide board layout advantages. ROHS3 compliance is maintained.

Upgrade Substitute: UPW2D470MHD

The UPW2D470MHD provides a voltage upgrade to 200 V while maintaining the same series, capacitance, tolerance, and lifetime specifications as the original part. Physical dimensions are identical, ensuring direct replacement capability. However, this part is also classified as Obsolete, limiting its long-term availability.

Direct Equivalent Substitutes (Same Voltage, Active Status):

UCY2C470MPD (Nichicon, Active) provides identical electrical specifications with extended 12000-hour lifetime at 105°C. Physical dimensions differ slightly: diameter reduced to 0.394" (10.00mm) and height to 0.846" (21.50mm). This part is suitable for applications where board space is constrained.

EKMG161ELL470MK20S (Chemi-Con, Active) and EKXG161ELL470MJ20S (Chemi-Con, Active) are alternative manufacturer options with identical electrical specifications. EKXG161ELL470MJ20S offers extended 8000-hour lifetime. Both maintain ROHS3 compliance and are suitable for applications requiring multi-source qualification.

SEK470M160ST (Cornell Dubilier Electronics, Active) is a third-party alternative with identical electrical specifications and 2000-hour lifetime. Diameter is slightly larger at 0.512" (13.00mm). This part is suitable for applications with established CDE component qualification.

Not Recommended for New Designs:

UVZ2C470MHD carries "Not For New Designs" status and should not be selected for new applications despite active inventory.

URZ2C470MHD has a significantly reduced lifetime of 1000 hours at 105°C and should only be considered for non-critical applications with short operational life requirements.

UPJ2C470MHD has different lead spacing (0.295" vs. 0.197") and larger physical dimensions, requiring PCB redesign for implementation.

Frequently Asked Questions (FAQ)

Q: Can UCS2E470MHD be used as a direct replacement for UPW2C470MHD?

A: Yes, UCS2E470MHD is electrically compatible as a direct replacement. The 250 V rating exceeds the original 160 V requirement, providing additional design margin. The lead spacing and diameter are identical. Height is reduced by 0.138" (4.60mm), which may require verification of board layout clearances but generally provides space savings.

Q: What is the difference between "Obsolete" and "Not For New Designs" product status?

A: Obsolete parts are no longer manufactured and have limited remaining inventory. Not For New Designs parts are still manufactured but are being phased out; they should not be selected for new product development. Both statuses indicate reduced long-term availability.

Q: Why do some substitute parts have different physical dimensions?

A: Different series within a manufacturer's product line may have different case sizes while maintaining the same electrical specifications. UCY2C470MPD and EKXG161ELL470MJ20S use smaller diameter cases (0.394" vs. 0.492"), which reduces board footprint but requires verification that the PCB layout can accommodate the different dimensions.

Q: Is the higher voltage rating of UCS2E470MHD (250 V vs. 160 V) a concern?

A: No. A higher voltage rating does not negatively affect circuit performance. The capacitor will operate safely at voltages up to 250 V. The higher rating provides additional safety margin and typically results in improved reliability characteristics.

Q: Can parts with different lead spacing be used interchangeably?

A: No. Lead spacing determines PCB hole pattern compatibility. UPJ2C470MHD (0.295" spacing) and URZ2C470MHD (0.295" spacing) have different lead spacing than the original UPW2C470MHD (0.197" spacing) and require PCB redesign for implementation.

Q: What does "Lifetime @ 105°C" mean?

A: This specification indicates the expected operational life of the capacitor when operated continuously at 105°C ambient temperature. Extended lifetime ratings (such as 12000 hours vs. 7000 hours) indicate improved long-term reliability and reduced degradation rates.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed carry ROHS3 compliance certification, matching the original part's environmental compliance status.

Q: Which substitute part offers the best overall performance?

A: UCS2E470MHD offers the best combination of active product status, extended lifetime (10000 hours), higher voltage rating (250 V), and direct PCB compatibility. For applications requiring identical physical dimensions and active status with extended lifetime, UCY2C470MPD is the preferred alternative.
