Key Parameters

Substitute Part Grouping Explanation

Substitution of the UP025SL2R7D-A-BZ is determined by the following critical parameters:

Mandatory Matching Criteria:

• Capacitance value: 2.7 pF
• Mounting type: Through Hole
• Package configuration: Axial with straight leads
• Application category: General Purpose

Allowable Parameter Variations:

• Voltage rating may exceed the original 50V specification, provided the substitute maintains compatibility with circuit design constraints
• Tolerance may be tighter than ±0.5pF
• Temperature coefficient may differ (C0G/NP0 acceptable as alternative to SL)
• Operating temperature range may be broader than -25°C ~ 85°C
• Product status transition from obsolete to active is acceptable

The substitute SA102A2R7CAR meets all mandatory criteria while providing enhanced electrical performance characteristics through higher voltage rating and improved temperature stability.

Engineering Selection Recommendations

Primary Substitute: SA102A2R7CAR

The SA102A2R7CAR from KYOCERA AVX is the qualified equivalent for the obsolete UP025SL2R7D-A-BZ. Selection of this substitute is supported by the following factors:

• Identical Capacitance Value: Both components provide 2.7 pF, ensuring functional equivalence in circuit operation
• Compatible Mounting Architecture: Axial through-hole configuration with straight leads permits direct mechanical and electrical substitution
• Enhanced Voltage Performance: The 200V rating of SA102A2R7CAR exceeds the original 50V specification, providing additional design margin and reliability in voltage-stressed applications
• Improved Temperature Stability: C0G/NP0 temperature coefficient provides superior frequency and temperature stability compared to SL coefficient
• Active Product Status: SA102A2R7CAR maintains active manufacturing status, ensuring long-term availability and supply chain continuity
• Compliance Certifications: RoHS3 compliance and REACH unaffected status confirm regulatory alignment with current electronic component standards
• Tighter Tolerance: ±0.25pF tolerance provides improved capacitance accuracy relative to the ±0.5pF specification of the original part

Physical Dimension Consideration: The SA102A2R7CAR exhibits larger physical dimensions (0.100" Dia x 0.170" L versus 0.079" Dia x 0.091" L). PCB layout verification is required to confirm accommodation of the substitute component within existing board space constraints.

Frequently Asked Questions (FAQ)

Q: Can SA102A2R7CAR be used as a direct replacement for UP025SL2R7D-A-BZ?

A: Yes. Both components share identical capacitance value (2.7 pF), mounting type (through-hole axial), and lead configuration (straight). The substitute provides equivalent electrical function with enhanced performance characteristics. Physical dimensions differ; PCB layout compatibility must be verified.

Q: What is the significance of the voltage rating difference (50V vs. 200V)?

A: The substitute's higher voltage rating (200V) indicates greater dielectric strength and operational margin. This characteristic is beneficial in applications where circuit voltage may approach or exceed the original 50V specification. No derating is required when substituting a higher-voltage component in a lower-voltage application.

Q: How do the temperature coefficients (SL vs. C0G/NP0) affect circuit performance?

A: Temperature coefficient defines capacitance variation across the operating temperature range. C0G/NP0 (substitute) provides superior temperature stability with minimal capacitance drift, whereas SL (original) exhibits greater temperature-dependent variation. For applications requiring stable capacitance across temperature extremes, the substitute offers improved performance.

Q: Are there any compliance or regulatory differences between these components?

A: The SA102A2R7CAR is RoHS3 compliant and REACH unaffected, confirming alignment with current environmental and regulatory standards. Both components carry EAR99 ECCN classification. The substitute's active product status ensures ongoing compliance maintenance and supply availability.

Q: What is the impact of the tolerance difference (±0.5pF vs. ±0.25pF)?

A: The substitute's tighter tolerance (±0.25pF) provides improved capacitance accuracy and reduced part-to-part variation. This characteristic is advantageous in precision filtering and frequency-dependent applications where capacitance accuracy directly influences circuit performance.

Q: Will the larger physical size of SA102A2R7CAR create installation issues?

A: The substitute is physically larger (0.100" Dia x 0.170" L versus 0.079" Dia x 0.091" L). PCB layout review is necessary to confirm that the increased dimensions do not conflict with adjacent components, trace routing, or mechanical constraints. Lead spacing and mounting hole compatibility remain unchanged due to identical axial configuration.

Q: Is the substitute available in the same packaging format?

A: The original UP025SL2R7D-A-BZ is supplied in standard packaging, while SA102A2R7CAR is available in Tape & Reel (TR) format. Both formats are compatible with standard through-hole assembly processes. Packaging format selection depends on production volume and assembly equipment capabilities.
