SH330M063ST Equivalent & Substitute Parts

Part Overview

The SH330M063ST is a 33 µF, 63 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part operates across a temperature range of -40°C to 105°C and is rated for 2000 hours at 105°C, suitable for general-purpose applications requiring stable capacitance and low equivalent series resistance.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the SH330M063ST is determined by strict adherence to the following electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Capacitance value must equal 33 µF
• Tolerance must be ±20% or tighter
• Rated voltage must be equal to or greater than 63 V
• Polarization must remain polar
• Operating temperature range must encompass -40°C to 105°C

Mechanical Compatibility Criteria:

• Lead spacing must equal 0.138" (3.50 mm)
• Can diameter must equal 0.315" (8.00 mm)
• Height must not exceed the PCB clearance of the original design
• Mounting type must remain through-hole
• Package type must remain radial, can

Compliance Criteria:

• RoHS3 compliance required
• ECCN and HTSUS classifications must align with export and tariff requirements

The substitute part 100ZLJ33M8X11.5 meets all electrical and mechanical compatibility requirements while offering enhanced performance characteristics in lifetime rating and ripple current capacity.

Parameter Comparison

Engineering Selection Recommendations

The 100ZLJ33M8X11.5 manufactured by Rubycon qualifies as a direct electrical substitute for the obsolete SH330M063ST. Selection of this substitute is based on the following engineering factors:

Electrical Equivalence: The substitute maintains identical capacitance (33 µF), tolerance (±20%), and operating temperature range (-40°C to 105°C). The rated voltage of 100 V exceeds the original 63 V specification, providing additional voltage margin in the application circuit.

Mechanical Compatibility: Lead spacing (0.138" / 3.50 mm) and can diameter (0.315" / 8.00 mm) are identical to the original part. The substitute height of 0.512" (13.00 mm) exceeds the original 0.453" (11.50 mm) by 0.059". PCB layout verification is required to confirm clearance availability for the increased height.

Performance Enhancement: The substitute offers superior lifetime rating (8000 hours at 105°C versus 2000 hours) and higher ripple current capacity at both low frequency (260.4 mA @ 120 Hz) and high frequency (620 mA @ 100 kHz), indicating improved thermal stability and reduced stress under operating conditions.

Compliance and Availability: Both parts maintain ROHS3 compliance. The substitute is classified as active product status with 17,165 units in stock, ensuring long-term availability compared to the obsolete original part.

Selection Constraint: Physical height clearance on the PCB must be verified before implementation. If the additional 0.059" height creates a design conflict, alternative substitutes with matching height specifications should be evaluated.

Frequently Asked Questions (FAQ)

Q: Can the 100ZLJ33M8X11.5 be used as a direct replacement for the SH330M063ST?

A: The 100ZLJ33M8X11.5 is electrically compatible as a substitute. Capacitance, tolerance, and operating temperature range are identical. Lead spacing and can diameter match the original specification. The substitute height is 0.059" greater; PCB clearance must be confirmed before installation.

Q: What is the significance of the higher 100 V rating on the substitute part?

A: The substitute's 100 V rating exceeds the original 63 V specification. This provides additional voltage margin and does not create incompatibility. The capacitor will function correctly in circuits designed for 63 V operation.

Q: Does the increased lifetime rating (8000 hours versus 2000 hours) affect circuit performance?

A: Lifetime rating indicates thermal stability at 105°C. The substitute's higher rating reflects improved capacitor design and materials. This does not alter electrical performance in the circuit but indicates reduced degradation over extended operation at elevated temperatures.

Q: Are there any compliance differences between the two parts?

A: Both parts are ROHS3 compliant. ECCN and HTSUS classifications are identical (EAR99 and 8532.22.0020 respectively), ensuring equivalent export and tariff treatment.

Q: What is the impact of higher ripple current ratings on the substitute?

A: The substitute's higher ripple current capacity (260.4 mA @ 120 Hz and 620 mA @ 100 kHz versus 110 mA and 154 mA respectively) indicates lower internal heating under AC stress. This is a performance advantage and does not create incompatibility with the original circuit design.

Q: Must the PCB layout be modified to accommodate the substitute?

A: Lead spacing and can diameter remain unchanged. The substitute height of 0.512" (13.00 mm) versus the original 0.453" (11.50 mm) requires verification of vertical clearance. If clearance is available, no PCB modification is necessary. If clearance is insufficient, alternative substitutes with matching height must be selected.

Q: Is the substitute part actively manufactured?

A: Yes. The 100ZLJ33M8X11.5 is classified as active product status with 17,165 units in current inventory, ensuring availability for production and maintenance applications.
