VHT2200M25 Equivalent & Substitute Parts

Part Overview

The VHT2200M25 is a 2200 µF, 25 V aluminum electrolytic capacitor manufactured by NTE Electronics, Inc. This radial, through-hole component is rated for 1000 hours at 105°C and is designed for general-purpose applications requiring reliable energy storage and filtering in electronic circuits. The part is currently active in production with 743 units in stock.

Substitute parts are identified when design requirements permit higher voltage ratings, extended operational lifetimes, or improved electrical characteristics while maintaining the same capacitance value, tolerance, physical form factor, and mounting compatibility.

Key Parameters

Substitute Part Grouping Explanation

The SEK222M035ST qualifies as a direct substitute for the VHT2200M25 based on the following alignment of critical parameters:

Matching Parameters:

• Capacitance: 2200 µF (identical)
• Tolerance: ±20% (identical)
• Lead Spacing: 0.295" (7.50 mm) (identical)
• Size / Dimension: 0.630" Dia (16.00 mm) (identical)
• Mounting Type: Through Hole (identical)
• Package / Case: Radial, Can (identical)
• Polarization: Polar (compatible)
• RoHS Status: ROHS3 Compliant (identical)

Allowable Differences:

• Voltage - Rated: 35 V (higher than 25 V) — permits use in circuits designed for 25 V operation
• Lifetime @ Temperature: 2000 Hrs @ 105°C (extended from 1000 Hrs) — provides improved reliability margin
• Operating Temperature Range: -55°C to 105°C (expanded lower bound) — extends operational envelope
• ESR: 100 mOhm (specified for substitute; not provided for main part)

The SEK222M035ST maintains identical physical footprint and electrical capacitance, enabling direct board-level substitution without layout modification.

Parameter Comparison

Engineering Selection Recommendations

VHT2200M25 Selection Criteria:

• Primary choice when circuit design specifies exactly 25 V rated voltage
• Suitable for applications with standard thermal cycling requirements (1000 Hrs @ 105°C)
• Appropriate for operating environments within -40°C to 105°C range
• Both main part and substitute are ROHS3 compliant and carry EAR99 ECCN classification

SEK222M035ST Selection Criteria:

• Applicable when circuit design permits 35 V rated voltage or higher
• Preferred for applications requiring extended operational lifetime (2000 Hrs @ 105°C)
• Suitable for environments with lower temperature extremes (-55°C minimum)
• Identical physical footprint enables direct PCB substitution
• Specified ESR of 100 mOhm provides quantified electrical performance metric

Both parts are active products with current inventory availability. Selection between them depends solely on circuit voltage specification and thermal lifetime requirements.

Frequently Asked Questions (FAQ)

Q: Can SEK222M035ST replace VHT2200M25 in a 25 V circuit?

A: Yes. The SEK222M035ST is rated for 35 V, which exceeds the 25 V circuit requirement. Higher voltage rating does not create incompatibility; the component operates safely at lower applied voltages.

Q: What is the physical difference between these parts?

A: Both parts share identical lead spacing (0.295" / 7.50 mm), diameter (0.630" / 16.00 mm), and mounting type (through-hole radial). Maximum seated height differs by 0.020" (0.50 mm): VHT2200M25 is 1.240" (31.50 mm); SEK222M035ST is 1.260" (32.00 mm). This minimal difference does not affect standard PCB clearance design.

Q: What does the ±20% tolerance mean?

A: Both parts have identical ±20% capacitance tolerance. Actual capacitance values will fall within the range of 1760 µF to 2640 µF for either part.

Q: Why does SEK222M035ST have double the lifetime rating?

A: The SEK222M035ST is rated for 2000 Hrs @ 105°C compared to 1000 Hrs @ 105°C for VHT2200M25. This indicates improved internal construction or materials in the substitute part, providing extended operational margin in high-temperature applications.

Q: Are both parts RoHS compliant?

A: Yes. Both VHT2200M25 and SEK222M035ST are ROHS3 compliant and carry identical HTSUS code 8532.22.0020.

Q: What does ESR mean, and why is it specified for the substitute?

A: ESR (Equivalent Series Resistance) is the internal resistance of the capacitor at operating frequency. The SEK222M035ST specifies 100 mOhm ESR. This parameter is not provided for the VHT2200M25 in the available data. Lower ESR generally indicates better high-frequency performance and lower heat generation.

Q: Can I use VHT2200M25 in place of SEK222M035ST?

A: No. If a circuit design specifies SEK222M035ST, the lower 25 V rating of VHT2200M25 creates a voltage margin violation. Always use the part specified or a higher-rated equivalent.
