Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UP050B823K-NACZ are identified based on strict electrical and mechanical parameter matching. The following criteria determine substitution eligibility:

Mandatory Matching Parameters:

• Capacitance value: 0.082 µF
• Voltage rating: 50V minimum
• Tolerance: ±10%
• Mounting type: Through hole
• Package configuration: Axial
• Lead style: Straight

Application-Dependent Parameters:

• Temperature coefficient (B vs. X7R) affects capacitance stability across temperature ranges
• Operating temperature range determines suitability for specific thermal environments
• Moisture sensitivity level impacts storage and handling requirements

The substitute part A823K15X7RF5UAA meets all mandatory electrical and mechanical parameters while offering enhanced temperature stability through X7R temperature coefficient and extended operating range (-55°C ~ 125°C versus -25°C ~ 85°C). Physical dimensions differ slightly but remain compatible with standard through-hole axial mounting footprints.

Engineering Selection Recommendations

Primary Substitute: A823K15X7RF5UAA

The A823K15X7RF5UAA is the qualified substitute for UP050B823K-NACZ based on the following engineering criteria:

Electrical Compatibility: All critical electrical parameters match exactly: 0.082 µF capacitance, ±10% tolerance, and 50V voltage rating. The substitute maintains functional equivalence in general-purpose applications.

Thermal Performance Enhancement: The X7R temperature coefficient provides superior capacitance stability across temperature extremes compared to the B coefficient of the original part. The extended operating range (-55°C ~ 125°C) encompasses the original specification (-25°C ~ 85°C), ensuring compatibility in broader thermal environments.

Mechanical Compatibility: Both components feature through-hole axial mounting with straight leads. Physical dimensions of the substitute (0.098" Dia x 0.150" L) are slightly larger than the original (0.087" Dia x 0.126" L) but remain compatible with standard PCB footprints designed for axial ceramic capacitors.

Compliance & Availability: The substitute is active product status with ROHS3 compliance and REACH unaffected designation, ensuring long-term availability and regulatory compliance. The original part's obsolete status necessitates transition to this active alternative.

Moisture Sensitivity: The substitute's not-applicable moisture sensitivity level indicates superior handling characteristics compared to the original MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can A823K15X7RF5UAA directly replace UP050B823K-NACZ in existing designs?

A: Yes. Both components share identical capacitance (0.082 µF), tolerance (±10%), and voltage rating (50V). The substitute's X7R temperature coefficient and extended operating range provide equal or superior performance. Physical dimensions differ slightly but remain compatible with standard through-hole axial mounting footprints.

Q: What is the difference between B and X7R temperature coefficients?

A: B temperature coefficient specifies capacitance change within ±15% across -25°C to 85°C. X7R temperature coefficient specifies capacitance change within ±15% across -55°C to 125°C. X7R provides broader temperature stability and wider operating range.

Q: Are there any PCB layout considerations when substituting this part?

A: The substitute is slightly larger (0.098" Dia x 0.150" L versus 0.087" Dia x 0.126" L). Verify adequate clearance in the PCB layout. Standard axial capacitor footprints accommodate this size variation.

Q: Why is the original part obsolete?

A: UP050B823K-NACZ is classified as obsolete by Taiyo Yuden. A823K15X7RF5UAA is an active product from Vishay Beyschlag/Draloric/BC Components, ensuring continued availability and manufacturing support.

Q: Does the substitute meet current compliance standards?

A: Yes. A823K15X7RF5UAA is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic components.

Q: What is the inventory status of the substitute?

A: A823K15X7RF5UAA has 917 pieces in new original stock, providing immediate availability for production requirements.
