Key Parameters

Substitute Part Grouping Explanation

Substitution of the SH2R2M200ST is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Capacitance: 2.2 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 200 V minimum (equal or higher acceptable)
• Polarization: Polar (exact match required)
• Mounting Type: Through Hole (exact match required)
• Package Type: Radial, Can (exact match required)
• Lead Spacing: 0.098" (2.50mm) (exact match required)

Secondary Compatibility Parameters:

• ESR @ 120Hz: 90.43 Ohm (±5% variance acceptable)
• Ripple Current @ 120 Hz: 25 mA minimum
• Ripple Current @ 10 kHz: 40 mA minimum
• Lifetime @ 105°C: 2000 Hrs minimum
• RoHS Compliance: ROHS3 Compliant (required)

Substitute parts are grouped into two categories: direct equivalents (matching all primary criteria at identical voltage rating) and upgrades (matching all primary criteria with higher voltage rating).

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent - Recommended Primary Substitute:

The SEK2R2M200ST is the preferred direct substitute for the SH2R2M200ST. Both parts share identical electrical specifications (2.2 µF, ±20%, 200 V, 2000 Hrs @ 105°C) with ESR values within 0.04 Ohm variance. The SEK2R2M200ST carries Active product status, ensuring long-term availability and supply chain continuity. This part is ROHS3 compliant and provides an extended operating temperature range (-40°C to 105°C versus -25°C to 105°C), offering improved performance margin in low-temperature applications. Physical dimensions show minor increases (0.248" diameter and 0.453" height versus 0.236" and 0.433"), which remain compatible with standard through-hole PCB layouts with 0.098" lead spacing.

Voltage Upgrade Option:

The SEK2R2M250ST provides a voltage upgrade path while maintaining all other electrical and mechanical specifications. This part operates at 250 V rated voltage with proportionally increased ripple current ratings (29 mA @ 120 Hz and 46.4 mA @ 10 kHz). The SEK2R2M250ST is suitable for applications where higher voltage margin or increased ripple current handling is beneficial. Physical dimensions and lead spacing remain identical to the direct equivalent.

Alternative Equivalent - Secondary Option:

The UPW2D2R2MED (Nichicon) provides electrical equivalence at 200 V with matching ripple current specifications. However, this part carries Obsolete product status, limiting its suitability for new designs or long-term procurement. ESR data is not specified for this part. The UPW2D2R2MED maintains identical height (0.433") to the original SH2R2M200ST but features a slightly larger diameter (0.248" versus 0.236"), requiring PCB layout verification.

Selection Basis:

• Active Product Status: SEK2R2M200ST and SEK2R2M250ST are both Active products, ensuring availability and manufacturing continuity.
• Compliance: All recommended substitutes are ROHS3 compliant, meeting regulatory requirements.
• Electrical Performance: Direct equivalents maintain ESR specifications within acceptable tolerance, ensuring circuit performance stability.
• Physical Compatibility: Lead spacing (0.098") and mounting type (Through Hole, Radial Can) are identical across all substitutes, enabling direct PCB replacement without layout modification.

Frequently Asked Questions (FAQ)

Q: Can the SEK2R2M200ST be used as a direct replacement for the SH2R2M200ST without PCB modification?

A: The SEK2R2M200ST is electrically equivalent and uses identical lead spacing (0.098"). However, physical dimensions differ slightly: diameter increases from 0.236" to 0.248", and height increases from 0.433" to 0.453". PCB layout must be verified to confirm adequate clearance around the component footprint. Lead spacing compatibility ensures electrical connection without modification.

Q: What is the advantage of using SEK2R2M250ST over SEK2R2M200ST?

A: The SEK2R2M250ST operates at 250 V rated voltage compared to 200 V, providing a 50 V safety margin in applications where voltage stress may approach the rated limit. Ripple current ratings are also increased (29 mA @ 120 Hz and 46.4 mA @ 10 kHz versus 25 mA and 40 mA). All other specifications, including capacitance, tolerance, lifetime, and physical dimensions, remain identical. Selection depends on circuit voltage requirements and thermal stress conditions.

Q: Why is the UPW2D2R2MED listed as a substitute if it is obsolete?

A: The UPW2D2R2MED is included as a historical reference and alternative source for existing inventory. It provides electrical equivalence at 200 V with matching ripple current specifications. However, Obsolete product status indicates limited or unavailable future supply. For new designs or long-term applications, the Active-status SEK2R2M200ST is the recommended choice.

Q: Are there any temperature range differences between substitutes?

A: Yes. The SH2R2M200ST operates from -25°C to 105°C, while SEK2R2M200ST, SEK2R2M250ST, and UPW2D2R2MED all operate from -40°C to 105°C. The extended lower temperature limit in substitute parts provides improved performance margin in cold-environment applications. All parts maintain identical 2000 Hrs lifetime rating at 105°C.

Q: What does ESR (Equivalent Series Resistance) mean for capacitor selection?

A: ESR represents the internal resistance of the capacitor at a specified frequency (120 Hz in this case). Lower ESR indicates better high-frequency performance and reduced heat generation under ripple current conditions. The SH2R2M200ST and SEK2R2M200ST both specify 90.43 Ohm and 90.47 Ohm respectively, representing equivalent performance. The UPW2D2R2MED does not specify ESR, making electrical performance comparison incomplete for this parameter.

Q: Can these capacitors be used in surface-mount applications?

A: No. All listed parts are Through Hole mounted components in Radial, Can package configuration. They are designed for insertion into PCB holes with lead spacing of 0.098" (2.50mm). Surface-mount applications require different package types not listed in this substitution group.

Q: What is ROHS3 compliance, and why is it important?

A: ROHS3 (Restriction of Hazardous Substances Directive 3) compliance indicates that the component meets European Union environmental standards by restricting the use of specific hazardous materials including lead, mercury, cadmium, and certain flame retardants. All listed substitutes are ROHS3 compliant, ensuring compatibility with modern manufacturing and regulatory requirements.

Q: Is the ±20% tolerance specification the same across all substitutes?

A: Yes. All listed parts specify ±20% capacitance tolerance, meaning the actual capacitance value can range from 1.76 µF to 2.64 µF. This tolerance is identical across SH2R2M200ST, SEK2R2M200ST, SEK2R2M250ST, and UPW2D2R2MED, ensuring equivalent circuit performance characteristics.
