Substitute Part Grouping Explanation

Substitution of the SH330M160ST is determined by strict adherence to the following electrical and mechanical parameters:

Primary Substitution Criteria:

Capacitance: 33 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: 160 V minimum (equal or higher voltage ratings are acceptable)
Polarization: Polar (radial aluminum electrolytic)
Lead Spacing: 0.197" (5.00 mm) (exact match required for PCB compatibility)
Mounting Type: Through Hole (exact match required)
Package / Case: Radial, Can (exact match required)

Secondary Compatibility Parameters:

Operating Temperature Range: -25°C to 105°C minimum (equal or wider range acceptable)
RoHS Compliance: ROHS3 Compliant (required for regulatory alignment)

Substitute parts are grouped into two categories based on voltage rating alignment:

Category 1: Direct Voltage Match (160 V)

UPW2C330MHD (Nichicon): Identical voltage rating with extended lifetime (7000 Hrs @ 105°C)
160LLE33MEFC10X16 (Rubycon): Identical voltage rating with significantly extended lifetime (20000 Hrs @ 105°C)

Category 2: Voltage Upgrade (200 V and 250 V)

EEU-EB2D330 (Panasonic): 200 V rating with extended lifetime (5000 Hrs @ 105°C)
EEU-EB2E330 (Panasonic): 250 V rating with extended lifetime (5000 Hrs @ 105°C)
EEU-ED2E330 (Panasonic): 250 V rating with significantly extended lifetime (10000 Hrs @ 105°C)

All substitute parts maintain identical capacitance, tolerance, lead spacing, and mounting configuration. Voltage upgrades provide design margin for applications requiring higher voltage headroom.

Engineering Selection Recommendations

For Direct Replacement (160 V Voltage Class):

The UPW2C330MHD from Nichicon provides a direct electrical and mechanical substitute with identical 160 V voltage rating. This part is classified as obsolete but offers a 3.5× improvement in lifetime (7000 Hrs vs. 2000 Hrs @ 105°C). The UPW2C330MHD maintains the same case diameter and height as the original SH330M160ST, ensuring PCB layout compatibility.

The 160LLE33MEFC10X16 from Rubycon is the preferred direct replacement for new designs. This part is active in production, ROHS3 compliant, and offers a 10× improvement in lifetime (20000 Hrs vs. 2000 Hrs @ 105°C). The case diameter is smaller (0.394" vs. 0.512"), which may provide PCB space savings. The extended operating temperature range (-40°C to 105°C) provides additional design margin.

For Voltage-Upgraded Designs (200 V and 250 V Classes):

The EEU-EB2D330 from Panasonic (200 V) and EEU-EB2E330 (250 V) are active production parts with 5000-hour lifetimes. These parts are suitable for applications requiring higher voltage headroom. The EEU-EB2D330 and EEU-EB2E330 have slightly increased height (0.866" vs. 0.787"), requiring PCB layout verification.

The EEU-ED2E330 from Panasonic (250 V) is the highest-performance substitute, offering 10000-hour lifetime at 105°C with active production status. This part maintains the original height dimension (0.787"), simplifying PCB integration. The ED-A series provides the longest operational life among all substitutes.

Compliance and Availability:

All substitute parts are ROHS3 compliant and suitable for applications requiring regulatory alignment. Active production status is confirmed for the Rubycon 160LLE33MEFC10X16 and all Panasonic EEU series parts, ensuring long-term procurement availability. The Nichicon UPW2C330MHD, while obsolete, remains available in current inventory.

Frequently Asked Questions (FAQ)

Q1: Can I use a higher voltage-rated capacitor (200 V or 250 V) as a direct substitute for the 160 V SH330M160ST?

A: Yes. Higher voltage ratings are electrically compatible with lower voltage applications. A 200 V or 250 V capacitor will function correctly in a 160 V circuit, providing additional voltage margin. However, PCB layout must accommodate potential dimensional differences. The EEU-EB2D330 (200 V) and EEU-EB2E330 (250 V) have increased height (0.866" vs. 0.787"), while the EEU-ED2E330 (250 V) maintains the original height.

Q2: What is the significance of the lifetime rating difference (2000 Hrs vs. 20000 Hrs @ 105°C)?

A: Lifetime rating indicates the expected operational duration at maximum rated temperature (105°C) before capacitance degradation exceeds the tolerance specification. The SH330M160ST has a 2000-hour lifetime, while the 160LLE33MEFC10X16 has a 20000-hour lifetime. For applications operating continuously at elevated temperatures, the extended lifetime provides longer service intervals and improved reliability.

Q3: Are there mechanical compatibility issues when substituting the SH330M160ST with smaller-diameter alternatives?

A: The 160LLE33MEFC10X16 has a smaller case diameter (0.394" vs. 0.512"), which may allow PCB space optimization. However, the lead spacing (0.197" / 5.00 mm) remains identical, ensuring footprint compatibility. PCB layout should be verified to confirm that the smaller diameter does not create clearance issues with adjacent components or traces.

Q4: Which substitute part is recommended for new product designs?

A: The 160LLE33MEFC10X16 from Rubycon is recommended for new designs. This part is active in production, ROHS3 compliant, offers a 10× improvement in lifetime (20000 Hrs @ 105°C), and has an extended operating temperature range (-40°C to 105°C). For applications requiring higher voltage margin, the EEU-ED2E330 from Panasonic (250 V, 10000 Hrs @ 105°C) is the highest-performance alternative.

Q5: What is the difference between the Panasonic EEU-EB2E330 and EEU-ED2E330, both rated at 250 V?

A: Both parts are 250 V, 33 µF, ±20% tolerance with identical lead spacing and mounting type. The primary difference is lifetime: the EEU-EB2E330 (EB-A series) has a 5000-hour lifetime, while the EEU-ED2E330 (ED-A series) has a 10000-hour lifetime at 105°C. The EEU-ED2E330 also maintains the original height dimension (0.787" vs. 0.866"), simplifying PCB integration.

Q6: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, meeting regulatory requirements for hazardous substance restrictions. The SH330M160ST is also ROHS3 compliant, ensuring consistency across the substitution chain.

Q7: Can I use the UPW2C330MHD as a long-term production substitute?

A: The UPW2C330MHD is classified as obsolete, indicating that Nichicon has discontinued production. While current inventory is available (2022 Pcs), long-term procurement cannot be guaranteed. For ongoing production, the active-status alternatives (160LLE33MEFC10X16 from Rubycon or Panasonic EEU series) are recommended to ensure supply chain continuity.

Q8: What are the ripple current specifications for the substitute parts?

A: The SH330M160ST specifies 180 mA @ 120 Hz and 288 mA @ 10 kHz. The UPW2C330MHD maintains identical ripple current ratings (180 mA @ 120 Hz, 288 mA @ 10 kHz). The Panasonic and Rubycon alternatives specify ripple current at different frequencies (100 kHz or 10 kHz), reflecting modern measurement standards. Direct comparison requires evaluation at the same frequency; higher ripple current capability generally indicates improved performance.
