UP050CH910J-B-BZ Equivalent & Substitute Parts

Part Overview

The UP050CH910J-B-BZ is a 91 pF ceramic capacitor rated at 50V with C0H temperature coefficient, manufactured by Taiyo Yuden in axial through-hole configuration. This component is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and production requirements. The part maintains 814 units in current inventory stock.

Substitution becomes necessary due to the obsolete product status, which may result in supply discontinuation. Equivalent parts must maintain the same capacitance value, tolerance, and mounting characteristics while meeting or exceeding the original voltage and temperature specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance value: 91 pF (exact match required)
• Tolerance: ±5% (exact match required)
• Mounting type: Through hole axial (exact match required)
• Lead style: Straight (exact match required)

Acceptable Parameter Variations:

• Voltage rating: Equal to or greater than 50V
• Operating temperature range: Equal to or wider than -25°C ~ 85°C
• Temperature coefficient: C0G/NP0 acceptable as equivalent to C0H (both provide stable performance across temperature range)
• Physical dimensions: Minor variations acceptable provided through-hole compatibility is maintained
• Moisture sensitivity: Equal to or lower MSL rating acceptable

The substitute part SA102A910JAA meets all mandatory matching criteria and exceeds minimum requirements in voltage rating, operating temperature range, and temperature coefficient classification.

Engineering Selection Recommendations

SA102A910JAA as Primary Substitute:

The SA102A910JAA is suitable for direct substitution based on the following factors:

1. Electrical Equivalence: Identical capacitance (91 pF) and tolerance (±5%) ensure circuit performance matching. The 200V rating provides additional safety margin beyond the original 50V specification.

2. Temperature Performance: The C0G/NP0 temperature coefficient classification provides equivalent stability to the C0H specification. The extended operating range (-55°C ~ 125°C) exceeds the original -25°C ~ 85°C requirement.

3. Product Status: Active manufacturing status ensures long-term availability and supply continuity, addressing the obsolescence of the original part.

4. Compliance Certifications: ROHS3 compliance and REACH unaffected status satisfy current regulatory requirements for new designs and production.

5. Physical Compatibility: Through-hole axial configuration with straight leads maintains PCB layout compatibility. The slightly larger physical dimensions (0.100" Dia x 0.170" L versus 0.087" Dia x 0.126" L) remain within standard through-hole spacing tolerances.

6. Moisture Handling: Not Applicable MSL rating indicates superior moisture resistance compared to the original MSL 1 specification.

Frequently Asked Questions (FAQ)

Q: Can SA102A910JAA replace UP050CH910J-B-BZ in existing designs?

A: Yes. The substitute part maintains identical capacitance and tolerance values. The higher voltage rating (200V vs. 50V) and extended temperature range (-55°C ~ 125°C vs. -25°C ~ 85°C) provide enhanced performance margins. Physical dimensions are slightly larger but remain compatible with standard through-hole PCB layouts.

Q: What is the difference between C0H and C0G/NP0 temperature coefficients?

A: Both C0H and C0G/NP0 are stable temperature coefficient classifications used in general-purpose ceramic capacitors. C0G and NP0 are equivalent designations for the same temperature stability class. Both provide minimal capacitance variation across the operating temperature range.

Q: Are there any PCB layout considerations when substituting this part?

A: The substitute part is slightly larger in physical dimension (0.100" Dia x 0.170" L versus 0.087" Dia x 0.126" L). Verify that PCB hole spacing and component clearances accommodate the larger body diameter. Standard through-hole spacing of 0.1" (2.54mm) centers is compatible with both parts.

Q: Does the substitute part meet current regulatory requirements?

A: Yes. SA102A910JAA carries ROHS3 compliance certification and REACH unaffected status, meeting current environmental and regulatory standards for electronic components.

Q: What is the inventory status of the substitute part?

A: SA102A910JAA is actively manufactured by KYOCERA AVX with 1149 units currently in stock, providing reliable supply availability compared to the obsolete original part.

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

A: The substitute part operates to 125°C maximum, exceeding the original specification of 85°C. Applications requiring operation above 125°C require alternative component selection.
