Key Parameters

Substitute Part Grouping Explanation

Substitution of the SH330M100ST is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Capacitance value: 33 µF (exact match required)
• Tolerance: ±20% (matching tolerance band)
• Voltage rating: 100 V (minimum acceptable rating)
• Polarization: Polar (electrolytic type)

Mechanical Parameters:

• Package configuration: Radial, Can
• Mounting type: Through Hole
• Lead spacing: 0.197" (5.00 mm)
• Physical diameter: 0.394" (10.00 mm)

Environmental & Compliance:

• Operating temperature range: minimum -40°C to 105°C
• RoHS3 compliance required

The substitute part EEU-FC2A330 meets all these criteria while offering enhanced performance characteristics including extended lifetime (3000 hours at 105°C versus 2000 hours) and improved ripple current handling at high frequencies.

Parameter Comparison

Engineering Selection Recommendations

The EEU-FC2A330 is a direct functional substitute for the SH330M100ST based on matching electrical and mechanical specifications. Selection of this substitute is supported by the following factors:

Product Status: The SH330M100ST is obsolete, while the EEU-FC2A330 maintains active production status, ensuring long-term availability and supply chain continuity.

Compliance: Both parts are ROHS3 compliant, maintaining regulatory alignment for applications subject to environmental restrictions.

Performance Enhancement: The EEU-FC2A330 provides superior performance characteristics including 50% extended lifetime (3000 hours versus 2000 hours at 105°C), higher ripple current capacity at both low and high frequencies, and an expanded operating temperature range (-55°C to 105°C versus -40°C to 105°C).

Mechanical Compatibility: Physical dimensions and lead spacing are equivalent, enabling direct board-level substitution without PCB redesign. The maximum seated height difference of 0.020" (0.50 mm) is within typical mechanical tolerances for through-hole applications.

Automotive Qualification: The EEU-FC2A330 carries AEC-Q200 qualification, indicating suitability for automotive-grade applications where applicable.

Frequently Asked Questions (FAQ)

Q: Can the EEU-FC2A330 be used as a direct replacement for the SH330M100ST on existing PCBs?

A: Yes. Both parts share identical lead spacing (0.197" / 5.00 mm), physical diameter (0.394" / 10.00 mm), and through-hole mounting configuration. The seated height difference of 0.020" (0.50 mm) does not affect board-level compatibility for standard through-hole applications.

Q: What are the key electrical parameters that must match for substitution?

A: Capacitance (33 µF), tolerance (±20%), voltage rating (100 V), and polarization (polar) must be identical. The EEU-FC2A330 matches all these parameters exactly.

Q: Does the EEU-FC2A330 meet the same compliance requirements?

A: Yes. Both the SH330M100ST and EEU-FC2A330 are ROHS3 compliant. The EEU-FC2A330 additionally carries AEC-Q200 automotive qualification and REACH unaffected status.

Q: What is the significance of the extended lifetime rating on the EEU-FC2A330?

A: The EEU-FC2A330 provides 3000 hours at 105°C compared to 2000 hours for the SH330M100ST. This represents a 50% increase in rated operational life under maximum temperature conditions, improving reliability margins in applications with extended service requirements.

Q: Are there differences in ripple current handling between these parts?

A: Yes. The EEU-FC2A330 supports higher ripple current at both low frequency (198.9 mA @ 120 Hz versus 160 mA) and high frequency (306 mA @ 100 kHz versus 224 mA @ 10 kHz), providing improved performance in switching power supply and high-frequency filtering applications.

Q: What is the operating temperature range difference?

A: The EEU-FC2A330 extends the lower operating limit to -55°C compared to -40°C for the SH330M100ST, providing broader temperature coverage for applications in cold environments.
