UP050B562K-A-BZ Equivalent & Substitute Parts

Part Overview

The UP050B562K-A-BZ is a 5600 pF ceramic capacitor rated at 50V with B temperature coefficient, manufactured by Taiyo Yuden in axial through-hole configuration. This part is classified as obsolete, necessitating identification of equivalent substitute components for ongoing production and repair applications. Substitute parts must maintain the same capacitance value, voltage rating, tolerance, and mounting characteristics while accommodating minor dimensional variations inherent to different manufacturers' specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the UP050B562K-A-BZ are qualified based on the following electrical and mechanical parameters:

Electrical Equivalence Requirements:

• Capacitance value: 5600 pF (exact match)
• Voltage rating: 50V (minimum requirement)
• Tolerance: ±10% (exact match)
• Mounting configuration: Through-hole axial (exact match)

Mechanical Compatibility Requirements:

• Lead style: Straight leads
• Package type: Axial ceramic capacitor
• Physical form factor: Compatible with axial PCB footprints

Acceptable Variations:

• Temperature coefficient: Substitute parts may employ X7R coefficient, which provides superior temperature stability compared to the original B coefficient specification
• Operating temperature range: Substitute parts may exceed the original range (-25°C ~ 85°C), providing broader operational capability
• Physical dimensions: Minor dimensional increases are acceptable provided the axial form factor and lead spacing remain compatible with standard PCB layouts
• Packaging format: Original part supplied in bulk; substitutes available in Tape & Reel or Tape & Box configurations

The identified substitute parts (A562K15X7RF5TAA and A562K15X7RF5UAA) satisfy all critical electrical parameters while offering enhanced temperature stability through X7R coefficient technology.

Parameter Comparison

Engineering Selection Recommendations

Product Status Consideration: The original UP050B562K-A-BZ is classified as obsolete, making substitution necessary for new production and field repairs. Both identified substitute parts (A562K15X7RF5TAA and A562K15X7RF5UAA) maintain active product status with established supply chains.

Compliance and Certification: Both substitute parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. The original part's compliance status is not specified in available documentation.

Temperature Coefficient Enhancement: Substitute parts employ X7R temperature coefficient technology, which provides superior capacitance stability across temperature extremes compared to the original B coefficient. The expanded operating range (-55°C ~ 125°C versus -25°C ~ 85°C) accommodates broader application environments without performance degradation.

Packaging Format Selection:

• A562K15X7RF5TAA (Tape & Reel): Suitable for automated assembly processes and high-volume production environments
• A562K15X7RF5UAA (Tape & Box): Suitable for manual assembly, repair operations, and lower-volume applications

Dimensional Compatibility: Substitute parts exhibit slightly larger physical dimensions (0.098" Dia x 0.150" L versus 0.087" Dia x 0.126" L). PCB layout verification is required to confirm clearance compatibility with existing footprints, though standard axial capacitor spacing typically accommodates this dimensional increase.

Frequently Asked Questions (FAQ)

Q: Can A562K15X7RF5TAA and A562K15X7RF5UAA be used interchangeably with UP050B562K-A-BZ?

A: Yes. Both substitute parts satisfy all critical electrical parameters: identical capacitance (5600 pF), tolerance (±10%), and voltage rating (50V). The primary difference is packaging format (Tape & Reel versus Tape & Box), which does not affect electrical performance or PCB mounting compatibility.

Q: What is the significance of the temperature coefficient change from B to X7R?

A: Temperature coefficient defines capacitance variation across operating temperature ranges. X7R coefficient provides tighter capacitance tolerance across temperature extremes compared to B coefficient, resulting in more stable circuit performance. This represents an improvement over the original specification.

Q: Are the dimensional differences between the original and substitute parts critical?

A: The substitute parts are slightly larger (0.098" Dia x 0.150" L versus 0.087" Dia x 0.126" L). Standard PCB axial capacitor footprints accommodate this variation. However, applications with space constraints require physical verification before implementation.

Q: What is the difference between A562K15X7RF5TAA and A562K15X7RF5UAA?

A: Both parts are electrically identical. The difference is packaging format: A562K15X7RF5TAA is supplied in Tape & Reel format for automated assembly, while A562K15X7RF5UAA is supplied in Tape & Box format for manual assembly and repair applications.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both A562K15X7RF5TAA and A562K15X7RF5UAA are ROHS3 compliant and REACH unaffected, meeting current environmental regulations.

Q: Can the substitute parts operate at the original operating temperature range (-25°C ~ 85°C)?

A: Yes. The substitute parts operate across -55°C ~ 125°C, which encompasses the original range. The expanded range provides additional operational margin for demanding applications.

Q: What inventory levels are available for the substitute parts?

A: A562K15X7RF5TAA: 861 Pcs New Original In Stock; A562K15X7RF5UAA: 757 Pcs New Original In Stock. Both parts maintain active inventory status.
