Key Parameters

Substitute Part Grouping Explanation

Substitution of the UP050CH910J-A-BZ is determined by the following critical parameters:

Mandatory Matching Criteria:

• Capacitance value: 91 pF
• Tolerance: ±5%
• Mounting type: Through Hole
• Package type: Axial
• Lead style: Straight

Allowable Variation Parameters:

• Voltage rating may exceed the original 50V specification, provided the substitute meets or exceeds this minimum requirement
• Temperature coefficient may differ (C0H vs. C0G/NP0), as long as the substitute maintains stability within the operating temperature range
• Operating temperature range may be broader than the original -25°C ~ 85°C specification
• Physical dimensions may vary within axial package constraints
• Product status may transition from obsolete to active

The SA102A910JAA from KYOCERA AVX qualifies as a substitute based on matching capacitance, tolerance, mounting type, package type, and lead style, while offering enhanced voltage rating and improved temperature stability characteristics.

Parameter Comparison

Engineering Selection Recommendations

The SA102A910JAA serves as a direct functional substitute for the obsolete UP050CH910J-A-BZ. The substitute maintains identical capacitance and tolerance specifications while providing enhanced electrical performance through a 200V voltage rating and extended operating temperature range (-55°C ~ 125°C versus -25°C ~ 85°C).

The substitute part carries active product status, ensuring long-term availability and supply chain continuity. ROHS3 compliance and REACH unaffected status provide regulatory alignment for applications subject to environmental and hazardous substance restrictions.

Physical dimensions increase slightly (0.100" Dia x 0.170" L versus 0.087" Dia x 0.126" L), requiring verification of available board space in existing designs. The axial through-hole mounting configuration remains unchanged, preserving lead compatibility and soldering procedures.

Frequently Asked Questions (FAQ)

Q: Can the SA102A910JAA replace the UP050CH910J-A-BZ in all applications?

A: The SA102A910JAA is electrically compatible for applications requiring 91 pF ±5% capacitance. The higher voltage rating (200V vs. 50V) and extended temperature range provide enhanced performance margins. Physical dimension differences must be evaluated for board layout compatibility.

Q: What is the significance of the temperature coefficient change from C0H to C0G/NP0?

A: Both temperature coefficients provide stable capacitance across the operating temperature range. C0G/NP0 (the substitute) offers superior stability with tighter capacitance variation across temperature extremes, beneficial for precision applications.

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

A: The substitute (SA102A910JAA) is ROHS3 compliant and REACH unaffected. The original part (UP050CH910J-A-BZ) compliance status is not specified. For applications requiring regulatory compliance documentation, the substitute provides explicit certification.

Q: Will the larger physical dimensions of the substitute cause installation issues?

A: The substitute dimensions (0.100" Dia x 0.170" L) are larger than the original (0.087" Dia x 0.126" L). PCB layout verification is required to confirm adequate clearance and lead spacing accommodation.

Q: Is the substitute part currently available?

A: The SA102A910JAA carries active product status with 1149 pieces in stock, ensuring immediate availability. The original UP050CH910J-A-BZ is obsolete with limited remaining inventory (893 pieces).
