UP050F223Z-A-BZ Equivalent & Substitute Parts

Part Overview

The UP050F223Z-A-BZ is a 0.022 µF ceramic capacitor rated for 50V with axial through-hole mounting. Manufactured by Taiyo Yuden, this component features an F temperature coefficient and operates across -25°C to 85°C. The part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing production and maintenance applications. Substitute parts must maintain the same capacitance value, voltage rating, and electrical performance characteristics while accommodating different mounting technologies and package formats.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UP050F223Z-A-BZ is determined by the following critical electrical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 0.022 µF (exact match required)
• Voltage rating: 50V minimum (equal or higher acceptable)
• Tolerance: Must accommodate circuit design requirements

Functional Compatibility Criteria:

• Dielectric material and temperature coefficient performance
• Operating temperature range coverage
• Compliance certifications (RoHS3, REACH status)
• Moisture sensitivity rating

The substitute part UMK105B7223KV-FR maintains identical capacitance and voltage specifications. However, this substitute employs surface-mount technology (0402 package) rather than through-hole axial mounting, requiring circuit board redesign and assembly process modification. The substitute features an X7R temperature coefficient with expanded operating range (-55°C ~ 125°C) and improved tolerance (±10% versus -20%, +80%), representing enhanced electrical performance characteristics.

Engineering Selection Recommendations

For Direct Replacement (Through-Hole Applications):

The UP050F223Z-A-BZ is obsolete with no direct through-hole axial equivalent provided in the substitute list. Designs requiring through-hole mounting must source alternative axial ceramic capacitors with matching 0.022 µF / 50V specifications from other manufacturers or evaluate circuit board redesign feasibility.

For Surface-Mount Redesign:

The UMK105B7223KV-FR serves as an electrical equivalent for applications permitting surface-mount technology migration. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating. The substitute provides superior tolerance performance (±10% versus -20%, +80%) and extended operating temperature range (-55°C ~ 125°C versus -25°C ~ 85°C). The substitute part carries "Not For New Designs" status, indicating limited long-term availability; however, current inventory of 67,743 units supports near-term production requirements.

Compliance Verification:

Both parts satisfy ROHS3 compliance requirements. The substitute includes REACH Unaffected status, providing additional regulatory documentation for international applications.

Frequently Asked Questions (FAQ)

Q: Can the UMK105B7223KV-FR directly replace the UP050F223Z-A-BZ in existing circuit boards?

A: No. The UMK105B7223KV-FR is a surface-mount 0402 package component, while the UP050F223Z-A-BZ is a through-hole axial component. Direct board-level substitution requires circuit board redesign and assembly process modification.

Q: Are the electrical specifications compatible between these parts?

A: Both parts provide 0.022 µF capacitance at 50V rating. The substitute offers improved tolerance (±10% versus -20%, +80%) and extended operating temperature range (-55°C ~ 125°C versus -25°C ~ 85°C). These differences represent enhanced performance rather than incompatibility.

Q: What is the significance of the temperature coefficient difference (F versus X7R)?

A: Temperature coefficient designates how capacitance changes with temperature. The F coefficient (main part) and X7R coefficient (substitute) follow different standards. The X7R specification provides more stable capacitance across the operating temperature range, particularly at temperature extremes.

Q: Does the tolerance difference affect circuit functionality?

A: Tolerance differences impact circuit performance based on application requirements. The substitute's ±10% tolerance is tighter than the main part's -20%, +80% tolerance, potentially improving circuit stability in applications sensitive to capacitance variation.

Q: Are both parts RoHS compliant?

A: Yes. Both UP050F223Z-A-BZ and UMK105B7223KV-FR are ROHS3 compliant. The substitute additionally carries REACH Unaffected status.

Q: What is the moisture sensitivity implication?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.

Q: Why is the substitute listed as "Not For New Designs"?

A: This status indicates the manufacturer does not recommend this part for new product development. However, the part remains available for existing production and maintenance applications. Current inventory levels support near-term requirements.
