Key Parameters

Substitute Part Grouping Explanation

Substitution of the UP025SL2R2D-A-BZ is determined by the following critical parameters:

Electrical Compatibility:

• Capacitance value of 2.2 pF with tolerance of ±0.5pF
• Voltage rating equal to or greater than 50V
• Temperature coefficient suitable for general-purpose applications

Mechanical Compatibility:

• Through-hole mounting configuration
• Axial package orientation
• Straight lead style

Environmental & Compliance:

• Moisture Sensitivity Level 1 (Unlimited)
• Operating temperature range encompassing -25°C to 85°C

Substitute parts must satisfy all electrical parameters while maintaining mechanical compatibility with the original axial through-hole footprint. Voltage rating may exceed the original specification without compromising substitution validity.

Parameter Comparison

Engineering Selection Recommendations

MA101A2R2DAA (KYOCERA AVX) qualifies as a functional substitute for the UP025SL2R2D-A-BZ based on the following criteria:

Electrical Equivalence: The substitute maintains identical capacitance (2.2 pF) and tolerance (±0.5pF) specifications. The rated voltage of 100V exceeds the original 50V requirement, providing additional design margin without electrical incompatibility.

Mechanical Compatibility: Both components utilize axial through-hole mounting with straight leads, ensuring direct footprint compatibility in existing circuit board designs.

Environmental Performance: The substitute operates across an extended temperature range (-55°C ~ 125°C) that encompasses the original operating window (-25°C ~ 85°C). Both components maintain MSL 1 (Unlimited) moisture sensitivity classification.

Product Status & Availability: The substitute is classified as Active product status with confirmed inventory availability (775 Pcs), addressing the obsolescence of the original component.

Compliance Considerations: The substitute is RoHS non-compliant and REACH Affected. Design teams must evaluate compliance requirements against project specifications prior to implementation.

Frequently Asked Questions (FAQ)

Q: Can the MA101A2R2DAA directly replace the UP025SL2R2D-A-BZ in existing designs?

A: Yes, electrical and mechanical compatibility is established. Both components share identical capacitance (2.2 pF), tolerance (±0.5pF), and axial through-hole configuration. The substitute's higher voltage rating (100V vs. 50V) and extended temperature range provide additional operational margin. Physical dimensions differ slightly; verify PCB layout clearance for the substitute's larger form factor (0.090" Dia x 0.160" L vs. 0.079" Dia x 0.091" L).

Q: What are the key differences between the main part and substitute?

A: Primary differences include manufacturer (Taiyo Yuden vs. KYOCERA AVX), temperature coefficient (SL vs. C0G/NP0), voltage rating (50V vs. 100V), operating temperature range (-25°C ~ 85°C vs. -55°C ~ 125°C), physical dimensions, and product status (Obsolete vs. Active). Electrical performance for the specified 2.2 pF capacitance and tolerance remains equivalent.

Q: Are there physical space constraints when substituting?

A: Yes. The substitute component is larger in both diameter (0.090" vs. 0.079") and length (0.160" vs. 0.091"). Verify available PCB space and lead routing clearance before implementation. The axial orientation and straight lead style remain compatible with original through-hole footprints.

Q: Does the temperature coefficient difference affect circuit performance?

A: The substitute's C0G/NP0 temperature coefficient provides superior stability compared to the original SL coefficient. This represents an improvement for temperature-sensitive applications. The extended operating range (-55°C ~ 125°C) accommodates broader environmental conditions than the original specification.

Q: What compliance factors should be considered?

A: The substitute is RoHS non-compliant and REACH Affected. Projects with RoHS compliance requirements must evaluate alternative sources or obtain exemptions. Verify project-specific regulatory requirements before component selection.

Q: Is the substitute available for immediate procurement?

A: Yes. The substitute (MA101A2R2DAA) is classified as Active product status with 775 Pcs confirmed in stock, ensuring supply continuity compared to the obsolete original component.
