Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 227HSM010M is determined by the following critical parameters:

Primary Matching Criteria:

• Capacitance: 220 µF (exact match required)
• Tolerance: ±20% (exact match required)
• Voltage Rating: 10 V minimum (equal or higher acceptable)
• Mounting Type: Through Hole (exact match required)
• Package / Case: Radial, Can (exact match required)
• Lead Spacing: 0.138" (3.50 mm) (exact match required)
• Polarization: Polar (exact match required)

Secondary Compatibility Factors:

• Operating Temperature Range: -40°C ~ 125°C minimum
• Lifetime @ Temperature: 2000 Hrs @ 125°C minimum
• Physical Dimensions: Diameter 0.315" (8.00 mm) and height compatibility with PCB layout

The substitute parts are grouped into three categories based on voltage rating and performance characteristics:

Direct Equivalent (Same Voltage): UBT1A221MPD8 and 510DX227M010BD2D maintain the 10 V rating, providing direct functional replacement with identical electrical stress conditions.

Upgrade Equivalents (Higher Voltage): 25RX30220M8X11.5 (25 V) and EEU-TA1C221 (16 V) provide higher voltage ratings, enabling use in applications with increased design margin or circuit voltage variations.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Same Electrical Stress):

UBT1A221MPD8 (Nichicon) is the preferred direct equivalent. This part maintains the 10 V rating, matching the original electrical stress conditions. The UBT series is active in production with substantial inventory availability (20,300 pcs). The part is ROHS3 compliant and REACH affected, meeting modern regulatory requirements. Operating temperature range and lifetime specifications are identical to the original part.

510DX227M010BD2D (Vishay Sprague) provides an alternative direct equivalent with identical ESR specification (1.507 Ohm @ 120 Hz) and voltage rating. This part is active in production and RoHS non-compliant. Physical height is significantly greater (0.709" vs. 0.512"), requiring PCB layout verification before selection.

For Upgraded Performance (Higher Voltage Rating):

25RX30220M8X11.5 (Rubycon) offers a 25 V rating with extended operating temperature to 130°C and AEC-Q200 automotive qualification. This upgrade provides increased design margin for circuits with voltage transients or tolerance stack-up. ROHS3 compliant and REACH unaffected. Physical height matches UBT1A221MPD8 at 0.531".

EEU-TA1C221 (Panasonic Electronic Components) provides a 16 V rating with the lowest impedance (130 mOhms) and highest ripple current capability (500 mA @ 100 kHz) among all substitutes. This part is ROHS3 compliant and REACH unaffected. Physical height is 0.492", the smallest among all options, offering potential space savings in compact layouts.

Regulatory and Compliance Considerations:

For applications requiring RoHS3 compliance, UBT1A221MPD8, 25RX30220M8X11.5, and EEU-TA1C221 are compliant. 510DX227M010BD2D is RoHS non-compliant and unsuitable for regulated applications.

For automotive applications, 25RX30220M8X11.5 carries AEC-Q200 qualification, indicating suitability for automotive-grade reliability requirements.

Frequently Asked Questions (FAQ)

Q: Can UBT1A221MPD8 be used as a direct replacement for 227HSM010M?

A: Yes. UBT1A221MPD8 matches all critical parameters: 220 µF capacitance, ±20% tolerance, 10 V rating, 0.138" lead spacing, radial can package, and through-hole mounting. Operating temperature range (-40°C ~ 125°C) and lifetime (2000 Hrs @ 125°C) are identical. Physical dimensions are compatible with standard PCB layouts.

Q: What is the difference between direct equivalents and upgrade equivalents?

A: Direct equivalents (UBT1A221MPD8, 510DX227M010BD2D) maintain the 10 V rating, preserving original electrical stress conditions. Upgrade equivalents (25RX30220M8X11.5 at 25 V, EEU-TA1C221 at 16 V) provide higher voltage ratings, enabling use in circuits with increased voltage margins or transient protection. Upgrade parts are suitable for applications where the original 10 V rating is marginal.

Q: Are there physical dimension constraints when substituting?

A: Yes. Lead spacing (0.138" / 3.50 mm) and diameter (0.315" / 8.00 mm) are identical across all substitutes, ensuring PCB hole compatibility. Height varies: 227HSM010M (0.512"), UBT1A221MPD8 (0.531"), 25RX30220M8X11.5 (0.531"), EEU-TA1C221 (0.492"), and 510DX227M010BD2D (0.709"). Verify clearance above the PCB for taller parts, particularly 510DX227M010BD2D.

Q: Which substitute offers the best ripple current performance?

A: EEU-TA1C221 provides the highest ripple current capability at 500 mA @ 100 kHz and the lowest impedance at 130 mOhms. This part is suitable for applications with high AC ripple current requirements. 25RX30220M8X11.5 offers 360 mA @ 100 kHz with 220 mOhms impedance. UBT1A221MPD8 provides 340 mA @ 100 kHz with 260 mOhms impedance.

Q: Is RoHS compliance a factor in substitute selection?

A: Yes, for regulated applications. UBT1A221MPD8, 25RX30220M8X11.5, and EEU-TA1C221 are ROHS3 compliant. 510DX227M010BD2D is RoHS non-compliant and must not be used in applications requiring RoHS certification.

Q: Can 510DX227M010BD2D be used despite its greater height?

A: 510DX227M010BD2D is electrically equivalent with identical ESR and voltage rating. However, its height of 0.709" (18.00 mm) exceeds the original 0.512" by 0.197" (5.00 mm). Use only if PCB clearance above the component is verified and no mechanical interference exists with adjacent components or enclosure.

Q: What is the inventory status for each substitute?

A: UBT1A221MPD8 has the highest availability at 20,300 pcs. 25RX30220M8X11.5 has 5,599 pcs. 510DX227M010BD2D has 923 pcs. EEU-TA1C221 has 1,682 pcs. Original 227HSM010M has 738 pcs remaining as new original stock.

Q: Which substitute is recommended for automotive applications?

A: 25RX30220M8X11.5 carries AEC-Q200 automotive qualification and is suitable for automotive-grade reliability requirements. UBT1A221MPD8 is specified for automotive applications but lacks explicit AEC-Q200 certification in the provided data.
