SH332M035ST Equivalent & Substitute Parts

Part Overview

The SH332M035ST is a 3300 µF, 35 V aluminum electrolytic capacitor in radial, can package manufactured by Cornell Dubilier Electronics (CDE). This component is classified as obsolete, indicating it is no longer in active production. The SH series represents legacy technology with a rated lifetime of 2000 hours at 105°C. Due to its obsolete status, equivalent and substitute parts from active manufacturers are necessary for ongoing system support, redesigns, and new production requirements.

Substitute Part Grouping Explanation

Substitution of the SH332M035ST is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

Capacitance: 3300 µF (exact match required)
Voltage Rating: 35 V (minimum; higher voltage ratings are acceptable upgrades)
Tolerance: ±20% (standard tolerance for this capacitance value)
Polarization: Polar (radial aluminum electrolytic type)
Mounting Type: Through Hole (radial lead configuration)
Package / Case: Radial, Can (physical form factor)
Lead Spacing: 0.295" (7.50 mm) (PCB footprint compatibility)
Size / Dimension: 0.709" Dia (18.00 mm) (can diameter)

Performance Parameters (Secondary Consideration):

ESR and Impedance: Lower values indicate improved performance
Lifetime @ Temperature: Higher values indicate extended operational life
Ripple Current Capability: Higher values indicate improved thermal performance
Operating Temperature Range: Extended ranges provide design flexibility

Substitute parts are grouped into two categories: direct equivalents (matching all critical parameters) and upgrades (enhanced performance characteristics while maintaining mechanical and electrical compatibility).

Engineering Selection Recommendations

Direct Equivalent (Same Manufacturer, Active Status):

SEK332M035ST from Cornell Dubilier Electronics is the direct equivalent replacement for the obsolete SH332M035ST. Both parts share identical electrical specifications (3300 µF, 35 V, ±20% tolerance, 70 mOhm ESR, 2000 Hrs @ 105°C) and mechanical dimensions. The SEK series is in active production status, ensuring long-term availability. The extended operating temperature range (-55°C to 105°C versus -40°C to 105°C) provides additional design margin. This part is recommended for direct substitution in existing designs.

Active Manufacturer Alternatives (Enhanced Performance):

Parts from Chemi-Con (EKY-350ELL332MMP1S, EKYB350ELL332MM25S, EKZN350ELL332MMN3S) and Panasonic (EEU-FC1V332) offer significantly improved performance characteristics while maintaining mechanical compatibility. These alternatives feature 5000 to 10000 hour lifetimes at 105°C (compared to 2000 hours for the original), lower impedance values (14-19 mOhms versus 70 mOhm), and higher ripple current ratings. All are ROHS3 compliant and in active production. Selection among these alternatives depends on specific application requirements for thermal performance and operational life.

Voltage Upgrade Option:

338CKE050M (50 V rating) is suitable for applications where higher voltage margin is required. This part maintains the same capacitance, tolerance, and mechanical form factor while providing 43% higher voltage rating. ESR and lifetime specifications are comparable to the original SH332M035ST.

Automotive-Qualified Alternatives:

EGPA350ELL332MM35S and ELXZ350ELL332MM35S carry AEC-Q200 automotive qualification and are suitable for automotive and harsh environment applications. These parts feature extended operating temperature ranges (up to 125°C) and improved reliability metrics.

Legacy Status Consideration:

UHE1V332MHD6 and UPW1V332MHD are marked "Not For New Designs" despite active inventory. These parts should be used only for legacy system support and field replacements, not for new product development.

Frequently Asked Questions (FAQ)

Q: Can SEK332M035ST be used as a direct replacement for SH332M035ST?

A: Yes. SEK332M035ST is the direct equivalent from the same manufacturer (Cornell Dubilier Electronics). Both parts have identical capacitance (3300 µF), voltage rating (35 V), tolerance (±20%), and ESR (70 mOhm). The SEK series is in active production, whereas the SH series is obsolete. Mechanical dimensions and lead spacing are identical, ensuring PCB compatibility.

Q: What is the difference between the substitute parts in terms of performance?

A: Substitute parts differ primarily in lifetime rating and impedance. The original SH332M035ST has a 2000-hour lifetime at 105°C with 70 mOhm ESR. Active alternatives from Chemi-Con and Panasonic offer 5000 to 10000-hour lifetimes with significantly lower impedance (14-19 mOhms). Lower impedance reduces heat generation and improves ripple current handling. Higher lifetime ratings extend operational reliability in demanding applications.

Q: Are all substitute parts mechanically compatible with the original SH332M035ST?

A: Mechanical compatibility requires matching lead spacing (0.295" / 7.50 mm), can diameter (0.709" / 18.00 mm), and mounting type (through-hole radial). Most alternatives meet these criteria. However, EKYB350ELL332MM25S has a reduced height (1.043" / 26.50 mm) compared to the original (1.417" / 36.00 mm), which may affect PCB layout in space-constrained designs. EKY-350ELL332MMP1S has a slightly increased height (1.457" / 37.00 mm). Verify physical clearance before selection.

Q: Which substitute part should be selected for new product designs?

A: For new designs, select from active manufacturer parts: SEK332M035ST (Cornell Dubilier), EKY-350ELL332MMP1S (Chemi-Con), EEU-FC1V332 (Panasonic), or EGPA350ELL332MM35S (Chemi-Con automotive-qualified). Avoid parts marked "Not For New Designs" (UHE1V332MHD6, UPW1V332MHD). Selection depends on application requirements for operating temperature range, lifetime, and automotive qualification.

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

A: Parts marked "Not For New Designs" are in limited production for legacy system support and field replacements only. These parts may have restricted availability, extended lead times, or planned discontinuation. They should not be specified in new product development. Use active status parts instead.

Q: Is the 50 V rated part (338CKE050M) a suitable substitute?

A: Yes, 338CKE050M is a suitable upgrade substitute. Higher voltage ratings provide additional design margin and are electrically compatible with 35 V circuits. The 50 V part maintains identical capacitance (3300 µF), tolerance (±20%), and mechanical form factor. Use this part when higher voltage stress margin is required or when 35 V parts are unavailable.

Q: What is the significance of AEC-Q200 qualification on automotive parts?

A: AEC-Q200 qualification indicates the part meets automotive industry reliability and quality standards. Parts EGPA350ELL332MM35S and ELXZ350ELL332MM35S carry this certification, making them suitable for automotive applications and harsh environments. These parts undergo additional testing for temperature cycling, vibration, and long-term reliability. Use AEC-Q200 qualified parts for automotive, industrial, and mission-critical applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the compliance status of the original SH332M035ST. ROHS3 compliance ensures the parts are free from restricted substances (lead, cadmium, mercury, hexavalent chromium, PBBs, PBDEs) and meet environmental regulations for electronic components.
