Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UP050CH620J-B-BZ is determined by the following critical parameters:

Mandatory Matching Criteria:

• Capacitance value: 62 pF
• Capacitance tolerance: ±5%
• Mounting type: Through Hole
• Package type: Axial
• Lead style: Straight

Allowable Parameter Variations:

• Voltage rating may exceed 50V (higher voltage rating provides backward compatibility)
• Temperature coefficient may differ (C0G/NP0 acceptable as alternative to C0H)
• Operating temperature range may be wider than -25°C ~ 85°C
• Product status may be active (preferred over obsolete)
• Moisture sensitivity level may differ

The SA102A620JAR from KYOCERA AVX qualifies as a substitute based on matching capacitance, tolerance, mounting configuration, and package type, while offering enhanced voltage rating and improved temperature stability characteristics.

Parameter Comparison

Engineering Selection Recommendations

The SA102A620JAR serves as a direct functional substitute for the UP050CH620J-B-BZ based on the following engineering criteria:

Electrical Compatibility: Both components maintain identical 62 pF capacitance and ±5% tolerance specifications. The substitute's 200V voltage rating exceeds the original 50V requirement, ensuring electrical compatibility in all applications where the main part operates. The C0G/NP0 temperature coefficient of the substitute provides superior temperature stability compared to the C0H coefficient of the original part.

Physical Compatibility: Both components utilize axial through-hole mounting with straight leads, enabling direct board-level substitution. The substitute exhibits slightly larger physical dimensions (0.100" Dia x 0.170" L versus 0.087" Dia x 0.126" L), which requires verification of available board space in confined layouts.

Compliance and Availability: The SA102A620JAR maintains active product status with ROHS3 compliance and REACH unaffected designation, providing long-term supply assurance and regulatory alignment. The original UP050CH620J-B-BZ is classified as obsolete, making the substitute the appropriate selection for new designs and production continuity.

Temperature Performance: The substitute's extended operating range (-55°C ~ 125°C) encompasses the original specification (-25°C ~ 85°C), providing enhanced thermal margin for demanding applications.

Frequently Asked Questions (FAQ)

Q: Can the SA102A620JAR directly replace the UP050CH620J-B-BZ in existing designs?

A: Yes, the SA102A620JAR provides direct electrical substitution. Both components share identical 62 pF capacitance, ±5% tolerance, and axial through-hole configuration. Physical board space must accommodate the slightly larger substitute dimensions (0.100" Dia x 0.170" L).

Q: What is the significance of the higher 200V rating on the substitute part?

A: The 200V rating on the SA102A620JAR exceeds the original 50V specification, ensuring the substitute operates safely in all applications designed for the original part. Higher voltage ratings do not negatively impact performance in lower-voltage applications.

Q: How do the temperature coefficients differ between these parts?

A: The original UP050CH620J-B-BZ uses C0H temperature coefficient, while the SA102A620JAR uses C0G/NP0 coefficient. C0G/NP0 provides superior temperature stability with minimal capacitance variation across temperature extremes, making it suitable for precision applications.

Q: Are there any compliance differences between the two parts?

A: The SA102A620JAR carries ROHS3 compliance and REACH unaffected designation. The original part's compliance status is not specified. For applications requiring regulatory compliance documentation, the substitute provides explicit certification.

Q: What physical considerations apply when substituting these components?

A: The substitute is slightly larger (0.100" Dia x 0.170" L) compared to the original (0.087" Dia x 0.126" L). Verify available board space and lead hole spacing in the PCB layout before implementation.

Q: Why is the original part classified as obsolete?

A: The UP050CH620J-B-BZ is marked obsolete by Taiyo Yuden, indicating discontinued manufacturing and limited availability. The SA102A620JAR, maintained in active production status by KYOCERA AVX, provides ongoing supply assurance for equivalent functionality.

Q: Can the substitute be used in high-temperature applications?

A: Yes, the SA102A620JAR operates to 125°C maximum, exceeding the original part's 85°C limit. This extended range supports applications requiring elevated temperature performance.
