Key Parameters

Substitute Part Grouping Explanation

Substitution for UP050B823K-A-BZ is based on electrical and mechanical parameter alignment. The primary substitution criteria are:

Electrical Parameters:

• Capacitance value: 0.082 µF (exact match required)
• Voltage rating: 50V (exact match acceptable; higher ratings not required)
• Tolerance: ±10% (exact match)
• Temperature coefficient: B-type or superior (X7R provides improved stability)

Mechanical Parameters:

• Mounting configuration: Through-hole axial (exact match required)
• Lead style: Straight (exact match required)
• Package case: Axial (exact match required)

Compliance Parameters:

• Product status: Active substitutes preferred over obsolete
• RoHS compliance: ROHS3 Compliant status preferred for regulatory alignment

The identified substitute parts A823K15X7RF5TAA and A823K15X7RF5UAA meet all electrical and mechanical requirements. Both are manufactured by Vishay Beyschlag/Draloric/BC Components and feature X7R temperature coefficient, which provides superior temperature stability compared to the original B coefficient while maintaining identical capacitance and voltage specifications.

Parameter Comparison

Engineering Selection Recommendations

Substitution Feasibility:

Both A823K15X7RF5TAA and A823K15X7RF5UAA are direct electrical and mechanical equivalents to UP050B823K-A-BZ. The substitutes satisfy all critical parameters: identical capacitance (0.082 µF), voltage rating (50V), tolerance (±10%), and through-hole axial mounting configuration.

Advantages of Substitutes:

1. Active Product Status: Both substitute parts are classified as active, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

2. Enhanced Temperature Stability: X7R temperature coefficient provides superior capacitance stability across temperature extremes (-55°C to 125°C) compared to B coefficient, extending operational reliability beyond the original specification range.

3. Regulatory Compliance: Both substitutes are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.

4. Physical Compatibility: Straight lead style and axial package configuration ensure direct PCB footprint compatibility. Slightly larger physical dimensions (0.098" Dia x 0.150" L versus 0.087" Dia x 0.126" L) do not impact through-hole insertion or standard PCB layouts.

Selection Between Substitutes:

• A823K15X7RF5TAA: Tape & Reel packaging suitable for automated assembly and high-volume production environments.
• A823K15X7RF5UAA: Tape & Box packaging suitable for manual assembly and lower-volume applications.

Both substitutes are electrically and mechanically interchangeable; packaging selection depends on assembly methodology and procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can A823K15X7RF5TAA and A823K15X7RF5UAA be used interchangeably with UP050B823K-A-BZ?

A: Yes. Both substitute parts meet all electrical specifications (0.082 µF, 50V, ±10% tolerance) and mechanical requirements (through-hole axial configuration, straight leads). The substitutes are electrically and mechanically compatible for direct replacement.

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

A: B coefficient specifies capacitance change of ±(0 to -30)% across -25°C to 85°C. X7R coefficient specifies capacitance change of ±15% across -55°C to 125°C. X7R provides superior stability and wider operating temperature range, making it suitable for applications requiring enhanced temperature performance.

Q: Are the physical size differences between the main part and substitutes significant?

A: The substitute parts are slightly larger (0.098" Dia x 0.150" L versus 0.087" Dia x 0.126" L). This difference does not impact standard through-hole PCB layouts or insertion compatibility. Verify PCB clearance in space-constrained designs.

Q: What is the difference between Tape & Reel and Tape & Box packaging?

A: Tape & Reel (TR) packaging is optimized for automated pick-and-place assembly equipment. Tape & Box (TB) packaging is suitable for manual assembly and lower-volume applications. Both contain identical components; packaging selection depends on assembly process requirements.

Q: Why is the substitute part classified as Active while the main part is Obsolete?

A: The UP050B823K-A-BZ has been discontinued by Taiyo Yuden. The substitute parts from Vishay Beyschlag/Draloric/BC Components remain in active production, ensuring ongoing availability and supply chain reliability for new designs and legacy system maintenance.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both A823K15X7RF5TAA and A823K15X7RF5UAA are ROHS3 Compliant and REACH Unaffected, meeting current environmental regulations for electronic component manufacturing and distribution.

Q: Can the substitute parts handle higher voltage applications?

A: No. The substitute parts are rated at 50V, identical to the main part. For applications requiring higher voltage ratings, alternative capacitor models with higher voltage specifications must be selected.

Q: What inventory levels are available for each part?

A: UP050B823K-A-BZ: 1050 Pcs; A823K15X7RF5TAA: 1035 Pcs; A823K15X7RF5UAA: 917 Pcs. All parts are listed as new original stock.
