Substitute Part Grouping Explanation

Substitution of the UHC1V221MPD is determined by the following critical parameters:

Capacitance: 220 µF (exact match required)
Tolerance: ±20% (exact match required)
Voltage Rating: 35 V (equal or higher voltage rating acceptable)
Polarization: Polar (must remain polar)
Mounting Type: Through Hole (must remain through hole)
Package / Case: Radial, Can (must remain radial, can)
Lead Spacing: 0.197" (5.00mm) preferred for direct PCB compatibility
Physical Dimensions: Size and height compatibility with PCB layout

Substitute parts are grouped into two categories:

Upgrade Parts feature improved performance characteristics such as extended lifetime ratings, higher temperature operation, or enhanced ripple current handling while maintaining core electrical specifications.

Similar Parts maintain equivalent electrical performance with variations in physical dimensions or lead spacing that may require PCB layout verification.

Engineering Selection Recommendations

For Active Production (Recommended First Choice)

UBT1V221MPD8 and UBW1V221MPD are the preferred substitutes as both carry Active product status and ROHS3 compliance. UBT1V221MPD8 offers extended lifetime (5000 hours at 125°C) with identical lead spacing and voltage rating. UBW1V221MPD extends the operating temperature range to -55°C to 135°C, suitable for automotive applications requiring wider temperature operation.

For Extended Lifetime Requirements

UHE1V221MPD6 provides the highest lifetime rating (7000 hours at 105°C) among 35 V rated parts with matching 0.197" lead spacing and compact height of 0.492", enabling space-constrained designs. This part maintains the same voltage and capacitance specifications as the original UHC1V221MPD.

For Higher Voltage Margin

UHD1H221MPD and UPS1H221MPD both feature 50 V ratings, providing additional voltage margin over the original 35 V specification. UHD1H221MPD offers 4000-hour lifetime at 105°C with identical physical dimensions to the original part.

For Automotive Applications

UPM1V221MPD6 carries AEC-Q200 qualification and is rated for automotive use with 5000-hour lifetime at 105°C and extended temperature range (-55°C to 105°C). Lead spacing and voltage match the original specification.

Dimensional Compatibility Considerations

Parts with 0.138" (4.60mm) lead spacing (UHD1V221MPD, UHE1V221MPD, UHV1V221MPD) require PCB layout verification as they differ from the original 0.197" (5.00mm) spacing. Height variations across substitute parts range from 0.492" to 0.709", requiring clearance verification in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can I use a 50 V rated capacitor in place of the 35 V UHC1V221MPD?

A: Yes. Higher voltage ratings are electrically compatible and provide additional safety margin. UHD1H221MPD and UPS1H221MPD both feature 50 V ratings with identical 220 µF capacitance and 0.197" lead spacing, making them direct physical substitutes.

Q: What is the difference between upgrade and similar substitute parts?

A: Upgrade parts (UBT1V221MPD8, UBW1V221MPD, UHD1H221MPD, UPM1V221MPD6, UPS1H221MPD) maintain the original lead spacing of 0.197" (5.00mm) for direct PCB compatibility. Similar parts (UHD1V221MPD, UHD1V221MPD6, UHE1V221MPD, UHE1V221MPD6, UHV1V221MPD) feature different lead spacing or physical dimensions requiring PCB layout verification.

Q: Why is the UHC1V221MPD obsolete, and which substitute should I choose for new designs?

A: The UHC series has been discontinued. For new designs, select from Active status parts: UBT1V221MPD8 for extended lifetime at elevated temperature, or UBW1V221MPD for automotive applications requiring wide temperature range operation. Both maintain identical lead spacing and voltage specifications.

Q: Does lead spacing affect electrical performance?

A: Lead spacing affects PCB layout compatibility only. Electrical performance remains equivalent across all substitute parts with matching capacitance, voltage, and tolerance specifications. Parts with 0.138" spacing require PCB redesign compared to the original 0.197" spacing.

Q: Are all substitute parts RoHS compliant?

A: The original UHC1V221MPD does not specify RoHS status. All listed substitute parts carry ROHS3 compliance, meeting current environmental and regulatory requirements for new production.

Q: What lifetime rating should I select for my application?

A: Lifetime ratings range from 2000 to 7000 hours at 105°C across substitute options. Select based on application duty cycle and expected service life. Extended lifetime parts (UHE series at 7000 hours) provide margin for long-term reliability in critical applications.

Q: Can I substitute parts with different operating temperature ranges?

A: Yes, if the substitute part's temperature range encompasses your application requirements. UBW1V221MPD extends to -55°C to 135°C, suitable for automotive and industrial environments. Standard parts operate -40°C to 105°C, adequate for consumer and general industrial use.
