Engineering Selection Recommendations

Primary Recommendation: SLPX223M010A7P3

The SLPX223M010A7P3 is the preferred direct substitute for the LPW223M1AN45V-W. This part maintains identical electrical specifications (22000 µF, 10 V, ±20% tolerance) with matching lead spacing (10.00 mm) and identical operating temperature range (-40°C to 85°C). The substitute offers improved performance through reduced ESR (33 mOhm versus 45 mOhm) and extended lifetime rating (3000 Hrs @ 85°C versus 1000 Hrs @ 85°C). Physical dimensions are compatible with through-hole mounting, with a reduced height (40.00 mm versus 45.00 mm) that provides additional design flexibility. The part is currently in active production status with ROHS3 compliance and REACH unaffected certification.

Secondary Recommendation: SLP223M010A4P3

The SLP223M010A4P3 provides an alternative with identical capacitance, voltage, and tolerance specifications. This part features extended operating temperature capability (-40°C to 105°C) and the highest lifetime rating (3000 Hrs @ 105°C), making it suitable for applications requiring enhanced thermal performance. Physical dimensions match the original part exactly (22.00 mm diameter, 45.00 mm height). The part is in active production status with full compliance certifications.

Tertiary Options: SLPX223M010C3P3 and SLPX223M010E1P3

Frequently Asked Questions (FAQ)

Q: Can SLPX223M010A7P3 be used as a direct replacement for LPW223M1AN45V-W without PCB modifications?

A: Yes. The SLPX223M010A7P3 maintains identical lead spacing (10.00 mm), mounting type (through hole), and package configuration (radial, can snap-in). The reduced height (40.00 mm versus 45.00 mm) provides additional clearance and does not require PCB modifications.

Q: What is the significance of the reduced ESR in substitute parts?

A: The substitute parts feature 33 mOhm ESR at 120 Hz compared to 45 mOhm in the original part. Lower ESR reduces heat generation and improves ripple current handling capability, resulting in enhanced performance and reliability.

Q: Are the dimensional variations in SLPX223M010C3P3 and SLPX223M010E1P3 compatible with the original PCB layout?

A: These parts feature different diameters (25.00 mm and 30.00 mm respectively) compared to the original 22.00 mm diameter. PCB mechanical envelope verification is required before selection. Lead spacing remains identical at 10.00 mm, maintaining electrical compatibility.

Q: What is the difference between SLP223M010A4P3 and SLPX223M010A7P3?

A: Both parts meet electrical specifications. SLP223M010A4P3 offers extended operating temperature range (-40°C to 105°C) and highest lifetime rating (3000 Hrs @ 105°C). SLPX223M010A7P3 maintains the original operating temperature range (-40°C to 85°C) with matching physical dimensions to the original part.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts listed are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: Can substitute parts be intermixed in the same application?

A: All substitute parts meet the mandatory electrical parameters (capacitance, voltage, tolerance, polarization). Mechanical envelope constraints must be verified for each specific PCB layout. Parts with identical physical dimensions (SLP223M010A4P3 and SLPX223M010A7P3) are directly interchangeable. Parts with dimensional variations require individual mechanical verification.

Q: What is the inventory status for substitute parts?

A: All substitute parts are currently in active production with confirmed inventory: SLP223M010A4P3 (852 Pcs), SLPX223M010A7P3 (950 Pcs), SLPX223M010C3P3 (1088 Pcs), and SLPX223M010E1P3 (939 Pcs).
