Engineering Selection Recommendations

Primary Recommendation: SEK330M200ST

The SEK330M200ST is the preferred direct upgrade from the obsolete SH330M200ST. Both are manufactured by Cornell Dubilier Electronics and maintain identical electrical specifications (33 µF, 200 V, ±20%, 6.03 Ohm ESR, 2000 Hrs @ 105°C). The SEK330M200ST offers active product status, ensuring long-term availability and supply chain stability. The extended operating temperature range (-40°C ~ 105°C versus -25°C ~ 105°C) provides additional thermal margin. The reduced height (0.827" versus 0.984") may require PCB layout verification for vertical clearance, though lead spacing and case diameter remain identical. ROHS3 compliance and REACH unaffected status confirm regulatory alignment.

Secondary Recommendation: SEK330M250ST

The SEK330M250ST provides a higher voltage rating (250 V versus 200 V) while maintaining the same 33 µF capacitance and ±20% tolerance. This part is suitable for applications where voltage margin enhancement is beneficial. Identical lead spacing (0.197") and case diameter (0.512") ensure mechanical compatibility. The reduced height (0.827") requires the same PCB clearance consideration as SEK330M200ST. Active product status and ROHS3 compliance apply.

Alternative Recommendation: EEU-EB2D330

The EEU-EB2D330 from Panasonic Electronic Components is a direct functional equivalent with identical capacitance, voltage, and tolerance specifications. This part offers extended lifetime (5000 Hrs @ 105°C versus 2000 Hrs), higher ripple current ratings (330 mA @ 120 Hz and 600 mA @ 100 kHz), and active product status. The case diameter is slightly smaller (0.492" versus 0.512"), and height is reduced (0.866" versus 0.984"). Lead spacing remains identical (0.197"). These dimensional differences require PCB layout verification. ROHS3 compliance and REACH unaffected status apply.

Alternative Recommendation: UCA2D330MHD

The UCA2D330MHD from Nichicon provides the highest lifetime rating (12000 Hrs @ 105°C) among all substitutes, with identical capacitance, voltage, and tolerance. Higher ripple current ratings (300 mA @ 120 Hz and 600 mA @ 100 kHz) support demanding applications. Product status is obsolete, which may limit future availability. Case diameter (0.492") and height (0.846") differ from the original, requiring PCB verification. Lead spacing remains compatible (0.197"). ROHS3 compliance and REACH unaffected status apply.

Alternative Recommendation: UPW2D330MHD

The UPW2D330MHD from Nichicon maintains identical ripple current specifications (190 mA @ 120 Hz and 304 mA @ 10 kHz) and height (0.984") as the SH330M200ST, minimizing PCB layout changes. Lifetime is 7000 Hrs @ 105°C, exceeding the original 2000 Hrs. Extended operating temperature range (-40°C ~ 105°C) provides thermal margin. Product status is obsolete. Case diameter (0.492") differs slightly. Lead spacing remains compatible (0.197"). ROHS3 compliance and REACH unaffected status apply.

Frequently Asked Questions (FAQ)

Q: Can SEK330M200ST directly replace SH330M200ST without PCB modification?

A: Electrical substitution is direct. However, the SEK330M200ST height is reduced from 0.984" to 0.827". Verify vertical clearance above the capacitor on the PCB. Lead spacing (0.197") and case diameter (0.512") are identical, so through-hole footprints remain compatible.

Q: What is the advantage of SEK330M250ST over SEK330M200ST?

A: The SEK330M250ST provides 250 V rating versus 200 V, offering 25% additional voltage margin. Capacitance, tolerance, and ESR remain identical. Use this part when circuit voltage stress analysis indicates benefit from higher voltage headroom. Height is identical to SEK330M200ST (0.827").

Q: Why do EEU-EB2D330 and UCA2D330MHD have different case diameters?

A: Panasonic and Nichicon use different can geometries for their aluminum electrolytic capacitor lines. The EEU-EB2D330 case diameter is 0.492" (12.50 mm) versus the original 0.512" (13.00 mm). This requires PCB footprint verification. Lead spacing remains standard at 0.197" (5.00 mm), so radial lead hole spacing is unchanged.

Q: Is UCA2D330MHD suitable for long-life applications despite obsolete status?

A: The UCA2D330MHD offers 12000 Hrs @ 105°C lifetime, the highest among all substitutes. Obsolete status indicates limited future procurement availability. For new designs, use active-status alternatives (SEK330M200ST or EEU-EB2D330). For existing equipment repair where this part was previously qualified, UCA2D330MHD remains electrically valid if current inventory is available.

Q: What is the difference between ripple current ratings at 120 Hz versus 10 kHz?

A: Ripple current capacity varies with frequency. The SH330M200ST and UPW2D330MHD specify 190 mA @ 120 Hz and 304 mA @ 10 kHz. The EEU-EB2D330 and UCA2D330MHD specify higher ratings at 100 kHz (600 mA), indicating superior high-frequency ripple current handling. Select based on actual circuit ripple frequency and magnitude.

Q: Can I use a 250 V rated capacitor in a 200 V circuit?

A: Yes. Higher voltage ratings are acceptable for lower voltage applications. The SEK330M250ST (250 V) operates safely in 200 V circuits. This provides voltage margin and may extend component lifetime. No circuit modification is required.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitutes (SEK330M200ST, SEK330M250ST, EEU-EB2D330, UCA2D330MHD, UPW2D330MHD) are ROHS3 compliant. The original SH330M200ST is also ROHS3 compliant. No environmental or regulatory concerns exist for substitution.

Q: What is the impact of extended operating temperature range (-40°C vs -25°C)?

A: SEK330M200ST, SEK330M250ST, and UPW2D330MHD extend the lower operating limit to -40°C, providing 15°C additional cold-temperature margin compared to the original SH330M200ST (-25°C). This is beneficial for equipment operating in cold environments or with wide ambient temperature ranges. Upper limit remains 105°C across all parts.

Q: Which substitute offers the best overall compatibility with the original SH330M200ST?

A: SEK330M200ST from Cornell Dubilier Electronics provides the closest match: identical manufacturer, same electrical specifications (33 µF, 200 V, ±20%, 6.03 Ohm ESR, 2000 Hrs @ 105°C), identical lead spacing and case diameter, and active product status. Height reduction (0.827" versus 0.984") is the only dimensional change, requiring PCB clearance verification.
