Substitute Part Grouping Explanation

Substitution for the UPS2C330MHD is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

Capacitance: 33 µF (exact match required)
Voltage Rating: 160 V minimum (equal or higher voltage acceptable)
Tolerance: ±20% (matching tolerance required)
Lead Spacing: 0.197" (5.00mm) (exact match required for PCB compatibility)
Case Diameter: 0.492" (12.50mm) (exact match required for mechanical fit)
Mounting Type: Through Hole (exact match required)
Package Type: Radial, Can (exact match required)
Operating Temperature: -40°C ~ 105°C (minimum range required)
Polarization: Polar (exact match required)

Secondary Considerations:

Lifetime @ 105°C: Equal or greater lifetime acceptable
Ripple Current Ratings: Equal or greater ripple current capability acceptable
Product Status: Active or Not For New Designs acceptable; Obsolete status indicates end-of-life

Substitutes are grouped into three categories: Direct equivalents (identical electrical and mechanical specifications), upgrades (improved lifetime or ripple current performance), and similar parts (different case dimensions or voltage ratings that may require design review).

Engineering Selection Recommendations

Direct Equivalents (Identical Mechanical Fit, Same Voltage):

UPS2C330MHD1TO is the direct equivalent with identical electrical and mechanical specifications. This part is available in Cut Tape packaging and carries a "Not For New Designs" status, indicating it remains available for legacy system support but is not recommended for new product development.

Upgraded Performance (Same Mechanical Fit, Enhanced Lifetime):

UPW2C330MHD provides 7000-hour lifetime at 105°C versus the original 3000 hours, with identical voltage and lead spacing. Height is reduced to 0.787" (20.00mm). Product status is Obsolete.

UCS2E330MHD and UCY2E330MHD3 offer significantly extended lifetimes (10000 and 12000 hours respectively) at higher voltage ratings (250 V). Both maintain the 0.492" (12.50mm) case diameter and 0.197" (5.00mm) lead spacing. Both carry Active product status, making them suitable for new designs requiring enhanced reliability.

UCY2V330MHD extends voltage rating to 350 V with 12000-hour lifetime and Active product status. Mechanical compatibility is maintained.

Higher Voltage Alternative (Same Mechanical Fit):

UVZ2E330MHD provides 250 V rating with identical case dimensions. Lifetime is 2000 hours at 105°C. Product status is Not For New Designs.

Cross-Manufacturer Alternative:

B43851K2336M000 (EPCOS - TDK Electronics) matches the original specifications with 33 µF, 250 V, identical case diameter and height, and Active product status. ESR is specified at 5.6 Ohm @ 120 Hz.

Compact Case Alternatives (Reduced Footprint):

UCY2C330MPD and UVY2C330MPD feature reduced case diameter (0.394" / 10.00mm) and height (0.689" / 17.50mm). These require PCB layout modification due to different lead spacing and case dimensions. UCY2C330MPD offers 12000-hour lifetime with Active status. UVY2C330MPD provides 2000-hour lifetime with Not For New Designs status.

Automotive-Qualified Option:

UPM2C330MHD1TO carries AEC-Q200 qualification for automotive applications with 5000-hour lifetime at 160 V. Height is increased to 1.063" (27.00mm), requiring mechanical clearance verification. Product status is Not For New Designs.

Frequently Asked Questions (FAQ)

Q: Can I use a 250 V rated capacitor in place of the 160 V UPS2C330MHD?

A: Yes. Higher voltage ratings are electrically compatible in circuits designed for lower voltages. The 250 V alternatives (UVZ2E330MHD, UCS2E330MHD, UCY2E330MHD3, UCY2V330MHD) maintain identical lead spacing and case diameter, ensuring mechanical compatibility. Verify that the increased height does not exceed available PCB clearance.

Q: What is the difference between UPS2C330MHD and UPS2C330MHD1TO?

A: Both parts are electrically and mechanically identical with 33 µF, 160 V, 3000-hour lifetime, and 0.492" case diameter. The primary difference is packaging: UPS2C330MHD is supplied in standard packaging, while UPS2C330MHD1TO is supplied in Cut Tape (CT) format. Both carry Not For New Designs or Obsolete status.

Q: Why would I choose UCY2C330MPD over the original UPS2C330MHD?

A: UCY2C330MPD offers four times the lifetime (12000 hours versus 3000 hours) and carries Active product status, making it suitable for new designs. However, it features a smaller case diameter (0.394" versus 0.492") and different height (0.689" versus 0.866"), requiring PCB layout modification. Use this part only if space constraints justify the redesign effort.

Q: Is the EPCOS B43851K2336M000 a suitable replacement?

A: Yes, for applications where cross-manufacturer sourcing is acceptable. The B43851K2336M000 matches the original case dimensions and lead spacing with 250 V rating and Active product status. It specifies ESR at 5.6 Ohm @ 120 Hz. Verify that your design does not require Nichicon-specific performance characteristics.

Q: Can I use UPM2C330MHD1TO in non-automotive applications?

A: Yes. The AEC-Q200 qualification indicates enhanced reliability suitable for automotive environments, but the part functions in general-purpose applications. The increased height (1.063" versus 0.866") requires clearance verification. Product status is Not For New Designs.

Q: What does "Not For New Designs" mean for product status?

A: Parts marked "Not For New Designs" remain available for existing product support and legacy system repairs but are not recommended for incorporation into new product development. Active status parts (UCS2E330MHD, UCY2E330MHD3, UCY2V330MHD, UCY2C330MPD, B43851K2336M000) are preferred for new designs.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitutes carry ROHS3 compliance. Verify REACH status for your specific application: most Nichicon parts are REACH Unaffected or REACH Affected; confirm requirements with your supply chain.
