UP025SL010D-A-BZ Equivalent & Substitute Parts

Part Overview

The UP025SL010D-A-BZ is a 1 pF ceramic capacitor manufactured by Taiyo Yuden, rated for 50V operation with SL temperature coefficient characteristics. This component is designed for through-hole axial mounting in general-purpose applications. The part is classified as obsolete, necessitating identification of equivalent alternatives for ongoing procurement and design continuity. Substitute parts must maintain electrical compatibility across capacitance, tolerance, voltage rating, and physical form factor while accommodating modern component availability and compliance requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UP025SL010D-A-BZ is determined by strict adherence to the following electrical and mechanical parameters:

Electrical Compatibility Requirements:

• Capacitance value must be 1 pF with tolerance of ±0.5pF
• Voltage rating must be equal to or greater than 50V
• Temperature coefficient must support the operating temperature range of -25°C to 85°C or broader

Physical Compatibility Requirements:

• Mounting type must be through-hole axial configuration
• Package case must be axial ceramic capacitor format
• Lead style must be straight for PCB insertion

Reliability and Compliance:

• Moisture Sensitivity Level must be 1 (Unlimited) or equivalent
• Product status should preferably be active for long-term availability

The MA101A1R0DAA from KYOCERA AVX qualifies as a substitute based on matching capacitance (1 pF), tolerance (±0.5pF), exceeding voltage rating (100V vs. 50V requirement), supporting the required operating temperature range through its broader specification (-55°C ~ 125°C), and maintaining identical through-hole axial mounting configuration with straight leads.

Parameter Comparison

Engineering Selection Recommendations

The MA101A1R0DAA serves as a direct electrical substitute for the UP025SL010D-A-BZ based on matching capacitance, tolerance, and mounting configuration. The substitute provides superior voltage rating (100V vs. 50V) and extended operating temperature range (-55°C ~ 125°C vs. -25°C ~ 85°C), offering enhanced performance margins for the application.

Physical Consideration: The substitute component is dimensionally larger (0.090" Dia x 0.160" L versus 0.079" Dia x 0.091" L). PCB layout verification is required to confirm that the increased axial length accommodates existing through-hole spacing and component clearances.

Compliance Status: The MA101A1R0DAA is classified as RoHS non-compliant and REACH Affected. Applications requiring RoHS compliance must evaluate this status against procurement requirements. The substitute maintains identical Moisture Sensitivity Level (1 - Unlimited) and ECCN classification (EAR99).

Availability: The substitute part is in active production status with confirmed inventory, providing long-term supply continuity compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can the MA101A1R0DAA replace the UP025SL010D-A-BZ in all applications?

A: Electrical substitution is valid for applications requiring 1 pF capacitance at 50V or lower. Physical verification of PCB layout is necessary due to the larger axial dimensions of the substitute (0.160" L vs. 0.091" L). Compliance requirements regarding RoHS status must be evaluated for the specific application.

Q: What is the significance of the different temperature coefficients (SL vs. C0G/NP0)?

A: The SL coefficient of the original part and the C0G/NP0 coefficient of the substitute indicate different temperature stability characteristics. The C0G/NP0 coefficient of the substitute provides superior frequency stability across temperature variations, representing an improvement over the original specification.

Q: Are there dimensional constraints for PCB integration?

A: Yes. The substitute part measures 0.160" in axial length compared to 0.091" for the original. Verify that existing PCB through-hole spacing, component clearances, and solder pad layouts accommodate the longer lead configuration. The diameter increase (0.090" vs. 0.079") is minimal and typically does not present integration challenges.

Q: What is the impact of the substitute being RoHS non-compliant?

A: RoHS non-compliance status must be evaluated against application and procurement requirements. If RoHS compliance is mandatory, alternative sources or design modifications may be necessary. The substitute maintains identical Moisture Sensitivity Level and ECCN classification as the original part.

Q: Is the higher voltage rating (100V vs. 50V) beneficial?

A: The higher voltage rating provides additional safety margin and stress reduction on the dielectric material, potentially extending component life and reliability in the application. This represents a performance enhancement for circuits operating at or below 50V.
