Substitute Part Grouping Explanation

Substitution of the UP050B272K-A-BZ is based on electrical and mechanical parameter alignment. The primary substitutes are Vishay Beyschlag/Draloric/BC Components parts A272K15X7RF5TAA and A272K15X7RF5UAA, which maintain the following critical parameters:

Matching Parameters:

• Capacitance: 2700 pF (identical)
• Tolerance: ±10% (identical)
• Voltage Rating: 50V (identical)
• Mounting Type: Through Hole (identical)
• Package Type: Axial (identical)
• Lead Style: Straight (identical)

Differing Parameters:

• Temperature Coefficient: X7R (substitute) versus B (original)
• Operating Temperature Range: -55°C ~ 125°C (substitute) versus -25°C ~ 85°C (original)
• Physical Dimensions: 0.098" Dia x 0.150" L (substitute) versus 0.087" Dia x 0.126" L (original)
• Product Status: Active (substitute) versus Obsolete (original)

The X7R temperature coefficient of the substitute parts provides superior temperature stability compared to the B coefficient of the original part, with an extended operating range that encompasses the original specification. Physical dimension differences are minor and remain within typical through-hole circuit board layout tolerances.

Parameter Comparison

Engineering Selection Recommendations

Both A272K15X7RF5TAA and A272K15X7RF5UAA are active production parts from Vishay Beyschlag/Draloric/BC Components, providing direct functional substitution for the obsolete UP050B272K-A-BZ. The substitute parts maintain identical electrical specifications for capacitance, tolerance, and voltage rating while offering enhanced temperature stability through X7R temperature coefficient classification.

The substitute parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement. The extended operating temperature range of -55°C to 125°C encompasses the original specification range, ensuring compatibility in applications operating within the original -25°C to 85°C window.

Physical dimension differences between the original and substitute parts are minor. The substitute parts measure 0.098" diameter by 0.150" length compared to the original 0.087" diameter by 0.126" length. These dimensional variations remain within standard through-hole component tolerances and do not preclude direct board-level substitution in typical circuit designs.

Selection between A272K15X7RF5TAA and A272K15X7RF5UAA depends on packaging requirements: A272K15X7RF5TAA is supplied in Tape & Reel format, while A272K15X7RF5UAA is supplied in Tape & Box format.

Frequently Asked Questions (FAQ)

Q: Can A272K15X7RF5TAA and A272K15X7RF5UAA be used interchangeably with UP050B272K-A-BZ?

A: Yes. Both substitute parts maintain identical capacitance (2700 pF), tolerance (±10%), and voltage rating (50V). The electrical performance is equivalent for general-purpose applications. Physical dimensions differ slightly but remain compatible with standard through-hole circuit board layouts.

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

A: The B temperature coefficient specifies capacitance change over a narrower temperature range (-25°C to 85°C) with defined tolerance limits. The X7R temperature coefficient specifies capacitance change over a wider temperature range (-55°C to 125°C) with tighter tolerance limits. X7R provides superior temperature stability and extended operating range.

Q: Are the substitute parts physically compatible with the original circuit board design?

A: The substitute parts are axial through-hole components with straight leads, matching the original mounting type. The dimensional increase (0.098" diameter versus 0.087" diameter, and 0.150" length versus 0.126" length) is minor and does not prevent direct board-level substitution in typical applications. Component spacing and lead hole sizing should be verified for specific board designs.

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

A: Both packaging formats contain the same electronic component. Tape & Reel (TR) format supplies components on continuous tape suitable for automated assembly equipment. Tape & Box (TB) format supplies components on tape within a protective box, suitable for manual assembly or lower-volume applications. Component electrical and mechanical specifications are identical.

Q: Are the substitute parts compliant with current regulatory standards?

A: Yes. Both A272K15X7RF5TAA and A272K15X7RF5UAA are ROHS3 compliant and REACH unaffected, meeting current electronic component procurement regulations.

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

A: A272K15X7RF5TAA is available with 823 pieces in stock. A272K15X7RF5UAA is available with 955 pieces in stock. Both are classified as new original components.
