SH330M035ST Equivalent & Substitute Parts Reference

Part Overview

The SH330M035ST is a 33 µF, 35 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, with 877 pieces currently in stock. The part is designed for general-purpose applications requiring through-hole mounting with a 0.098" (2.50 mm) lead spacing.

Due to the obsolete status of the SH330M035ST, equivalent and substitute parts from active manufacturers are necessary to ensure long-term component availability and supply chain continuity for new designs and production runs.

Engineering Selection Recommendations

For New Designs and Production:

Select from active-status substitute parts to ensure long-term availability and supply chain reliability:

EEU-EB1J330S (Panasonic): Recommended for applications requiring extended operational life. Active product status with 5000 Hrs lifetime at 105°C. 63 V rating provides design margin above the original 35 V specification. ROHS3 compliant.
EKZE630ELL330MF11D (Chemi-Con): Recommended for applications with space constraints or high ripple current requirements. Active product status with 2000 Hrs lifetime at 105°C. 63 V rating and higher ripple current capability (265 mA @ 100 kHz). ROHS3 compliant.
ESH336M050AE3AA (KEMET): Recommended for applications where case diameter must remain at 6.00 mm (matching original SH330M035ST). Active product status with 2000 Hrs lifetime at 105°C. 50 V rating provides modest design margin. ROHS3 compliant.

For Existing Equipment Maintenance:

Obsolete-status substitutes (UHE1J330MED, UPW1J330MED, UPW1H330MED) are available for repair and maintenance of existing systems. These parts maintain full compatibility with the original SH330M035ST in terms of electrical and mechanical specifications. However, for new production, active-status alternatives are preferred.

Voltage Rating Consideration:

All substitute parts are rated at 50 V or higher, compared to the original 35 V rating. This provides additional design margin and is electrically compatible with circuits designed for 35 V operation. No circuit modification is required.

Physical Fit Verification:

Most substitute parts feature a case diameter of 6.30 mm (compared to the original 6.00 mm) and heights ranging from 11.00 mm to 12.50 mm. Verify PCB layout and mechanical clearances before final component selection, particularly for applications with space constraints.

Frequently Asked Questions (FAQ)

Q1: Can I use a 63 V rated capacitor in place of the 35 V SH330M035ST?

A: Yes. A higher voltage rating is electrically compatible with circuits designed for lower voltage operation. The 63 V substitutes (EEU-EB1J330S, EKZE630ELL330MF11D, UHE1J330MED, UPW1J330MED) provide additional design margin and are direct functional replacements.

Q2: What is the difference between "Upgrade" and "Similar" substitute categories?

A: Upgrade substitutes feature higher voltage ratings (50 V or 63 V) compared to the original 35 V specification. Similar substitutes maintain equivalent or near-equivalent voltage ratings (50 V). Both categories are electrically compatible; the distinction reflects the degree of design margin provided.

Q3: Does the case diameter difference (6.00 mm vs. 6.30 mm) affect compatibility?

A: Case diameter is a mechanical consideration. The 6.30 mm diameter substitutes are slightly larger than the original 6.00 mm part. Verify PCB layout, component spacing, and mechanical clearances to confirm fit. The ESH336M050AE3AA maintains the original 6.00 mm diameter if space is critical.

Q4: Why do some substitutes have different heights (11.00 mm vs. 12.20 mm vs. 12.50 mm)?

A: Height variation reflects different internal construction and performance characteristics among manufacturers. All heights are within acceptable ranges for through-hole mounting. Verify PCB clearance above the component to confirm fit in your application.

Q5: Should I select an active-status or obsolete-status substitute?

A: For new designs and production, select active-status parts (EEU-EB1J330S, EKZE630ELL330MF11D, ESH336M050AE3AA) to ensure long-term availability. Obsolete-status parts are suitable for maintenance and repair of existing equipment only.

Q6: What does "5000 Hrs @ 105°C" lifetime mean compared to "2000 Hrs @ 105°C"?

A: Lifetime specification indicates the expected operational duration at maximum rated temperature (105°C) before capacitance degradation reaches specified limits. A 5000 Hrs rating provides extended operational life compared to 2000 Hrs. Both are acceptable for the SH330M035ST application; selection depends on system requirements.

Q7: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the compliance status of the original SH330M035ST.

Q8: Can I use UPW1H330MED (50 V) instead of a 63 V substitute?

A: Yes. The UPW1H330MED is rated at 50 V, which exceeds the original 35 V specification and is electrically compatible. However, it is classified as obsolete. For new production, prefer active-status alternatives.

Q9: What is the significance of lead spacing (0.098" / 2.50 mm)?

A: Lead spacing determines PCB hole pitch and component footprint compatibility. All substitute parts maintain the identical 0.098" (2.50 mm) lead spacing as the original SH330M035ST, ensuring direct PCB compatibility without layout modification.

Q10: Do I need to test substitutes before using them in production?

A: All substitute parts are electrically and mechanically compatible with the SH330M035ST based on provided specifications. Verify physical fit (case diameter and height) in your specific PCB layout and mechanical assembly before production release.
