UP050F474Z-A-BZ Equivalent & Substitute Parts

Part Overview

The UP050F474Z-A-BZ is a 0.47 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 core electrical characteristics while accommodating different mounting technologies and package formats.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UP050F474Z-A-BZ is determined by the following critical electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Capacitance value: 0.47 µF (exact match required)
• Voltage rating: 50V minimum (equal or higher acceptable)
• Tolerance: Must accommodate circuit design requirements

Mechanical and Compliance Criteria:

• RoHS3 compliance status
• Moisture sensitivity level
• Operating temperature range compatibility with application requirements

The identified substitute UMK107B7474KA-TR maintains identical capacitance and voltage specifications. However, this substitute represents a technology transition from axial through-hole to surface-mount multilayer ceramic capacitor (MLCC) format. This substitution requires circuit board redesign and assembly process modification. The substitute features improved temperature stability (X7R coefficient vs. F coefficient) and extended operating temperature range (-55°C to 125°C vs. -25°C to 85°C).

Engineering Selection Recommendations

For Direct Replacement (Through-Hole Applications):

The UP050F474Z-A-BZ is obsolete with no direct axial through-hole equivalent provided in the substitute list. Continued use of existing inventory is permissible for maintenance and repair of legacy equipment. New production designs should transition to surface-mount technology.

For New Designs and Production Transition:

The UMK107B7474KA-TR serves as the functional equivalent for new designs, provided circuit board layout and assembly processes accommodate surface-mount MLCC technology. This substitute offers superior tolerance control (±10% vs. -20%, +80%), extended temperature range, and improved temperature stability through X7R dielectric characteristics. Both parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring regulatory and environmental compatibility.

The substitute part status of "Not For New Designs" reflects manufacturer lifecycle management rather than technical unsuitability. Taiyo Yuden recommends evaluation of current-generation alternatives for long-term production programs.

Frequently Asked Questions (FAQ)

Q: Can the UMK107B7474KA-TR directly replace the UP050F474Z-A-BZ in existing circuit boards?

A: No. The UP050F474Z-A-BZ uses axial through-hole mounting, while the UMK107B7474KA-TR is a surface-mount 0603 package. Direct board-level substitution requires circuit board redesign and assembly process modification.

Q: Are the electrical specifications compatible between these parts?

A: Both parts share identical capacitance (0.47 µF) and voltage rating (50V). The substitute features tighter tolerance (±10% vs. -20%, +80%) and superior temperature stability (X7R vs. F coefficient). These differences are advantageous for circuit performance.

Q: What is the significance of the temperature coefficient difference?

A: The F coefficient in the main part indicates capacitance variation of ±3.3% across the operating temperature range. The X7R coefficient in the substitute indicates ±15% variation across its wider temperature range (-55°C to 125°C). For applications operating within -25°C to 85°C, both coefficients provide acceptable performance.

Q: Are both parts RoHS compliant?

A: Yes. Both the UP050F474Z-A-BZ and UMK107B7474KA-TR are ROHS3 compliant with moisture sensitivity level 1 (unlimited), meeting current regulatory requirements.

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

A: This designation reflects Taiyo Yuden's product lifecycle management. The part remains available and functional but is not recommended as the primary choice for new production programs. Current-generation alternatives may offer enhanced features or improved availability.

Q: What inventory considerations apply to the UP050F474Z-A-BZ?

A: The main part is obsolete with 932 pieces in stock. The substitute UMK107B7474KA-TR has significantly higher availability (1,966,831 pieces), supporting volume production requirements for new designs.
