Substitute Part Grouping Explanation

Substitution of aluminum electrolytic capacitors is determined by strict equivalence in the following parameters:

Primary Equivalence Criteria:

Capacitance value (220 µF)
Voltage rating (10 V minimum)
Tolerance (±20%)
Package type (Radial, Can)
Lead spacing (0.098" / 2.50 mm)
Case diameter (0.248" / 6.30 mm)
Mounting type (Through Hole)
Polarization (Polar)

Secondary Compatibility Factors:

Operating temperature range (-55°C to 105°C)
Lifetime rating (2000 Hrs @ 105°C)
RoHS3 compliance
REACH unaffected status

Substitute parts are classified into three categories based on their relationship to the main part:

Direct Equivalents: Parts with identical electrical and mechanical specifications
Direct Substitutes: Parts with equivalent core parameters but different manufacturers or series designations
Upgrade Substitutes: Parts with higher voltage ratings or enhanced electrical characteristics that maintain mechanical compatibility

Engineering Selection Recommendations

Primary Selection: ELXZ100ELL221MFB5D (Chemi-Con LXZ Series)

The ELXZ100ELL221MFB5D is the recommended direct equivalent for the 227KXM010M. This part maintains identical electrical specifications (220 µF, 10 V, ±20% tolerance) and mechanical compatibility (lead spacing, case diameter, through-hole mounting). The part carries Active product status, ensuring continued availability. AEC-Q200 automotive qualification provides additional reliability assurance. The maximum height of 0.512" (13.00 mm) represents a 0.020" increase over the main part but remains within typical PCB layout tolerances for radial capacitor applications. ROHS3 compliance and REACH unaffected status align with regulatory requirements.

Secondary Selection: UPS1A221MED (Nichicon UPS Series)

The UPS1A221MED provides parametric equivalence with identical electrical ratings (220 µF, 10 V, ±20% tolerance) and mechanical dimensions matching the main part exactly. This part is suitable for general purpose applications. Obsolete product status indicates limited future availability; selection should be based on current inventory requirements and project timelines.

Upgrade Selection: UKA1C221MED (Nichicon UKA Series)

The UKA1C221MED offers a voltage rating upgrade to 16 V while maintaining the 220 µF capacitance and ±20% tolerance. Mechanical compatibility is preserved with identical lead spacing, case diameter, and height. This upgrade is applicable in designs where increased voltage margin is beneficial. Obsolete product status limits availability.

Not Recommended: UKA1A221MED (Nichicon UKA Series)

While the UKA1A221MED meets all electrical and mechanical equivalence criteria, its Obsolete product status and limited future availability make it unsuitable for new designs or long-term production requirements.

Frequently Asked Questions (FAQ)

Q: Can the ELXZ100ELL221MFB5D be used as a direct replacement for the 227KXM010M?

A: Yes. The ELXZ100ELL221MFB5D meets all primary equivalence criteria: 220 µF capacitance, 10 V voltage rating, ±20% tolerance, identical lead spacing (0.098" / 2.50 mm), identical case diameter (0.248" / 6.30 mm), and through-hole radial mounting. The maximum height difference of 0.020" (0.512" versus 0.492") is within standard PCB layout tolerances for radial capacitor footprints.

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

A: Direct equivalents maintain identical electrical and mechanical specifications as the main part. Upgrade substitutes provide enhanced characteristics, such as higher voltage ratings, while preserving mechanical compatibility. The UKA1C221MED is an upgrade substitute with a 16 V rating compared to the 10 V main part, allowing use in higher voltage applications.

Q: Why are some substitute parts listed as Obsolete?

A: Obsolete product status indicates that the manufacturer has discontinued production. While these parts may be available from existing inventory, they are not recommended for new designs or applications requiring long-term component availability. The UKA1A221MED and UKA1C221MED are obsolete Nichicon products.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed in this reference maintain ROHS3 compliance and REACH unaffected status, matching the regulatory compliance of the main part 227KXM010M.

Q: What electrical parameters determine substitution compatibility?

A: The primary electrical parameters are capacitance (220 µF), voltage rating (10 V minimum), and tolerance (±20%). These parameters must match exactly for direct substitution. Secondary factors include operating temperature range (-55°C to 105°C) and lifetime rating (2000 Hrs @ 105°C).

Q: Can the UPS1A221MED be used in place of the 227KXM010M?

A: Yes. The UPS1A221MED is a parametric equivalent with matching capacitance, voltage, tolerance, and mechanical dimensions. However, its Obsolete product status limits suitability for new production designs.

Q: What is the significance of lead spacing and case diameter in substitution?

A: Lead spacing (0.098" / 2.50 mm) and case diameter (0.248" / 6.30 mm) determine PCB footprint compatibility. All substitute parts maintain these dimensions, ensuring direct mechanical compatibility without PCB redesign.

Q: Does the height difference of the ELXZ100ELL221MFB5D affect compatibility?

A: The ELXZ100ELL221MFB5D has a maximum height of 0.512" compared to 0.492" for the main part. This 0.020" difference is within standard PCB layout clearances for radial capacitor applications and does not affect electrical performance or mechanical mounting.
