Key Parameters

Substitute Part Grouping Explanation

Substitution of the UP050CH911J-A-BZ is determined by the following critical parameters:

Mandatory Matching Criteria:

• Capacitance value: 910 pF
• Tolerance: ±5%
• Mounting type: Through Hole
• Package type: Axial
• Lead style: Straight

Allowable Variation Parameters:

• 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
• Physical dimensions may vary within axial package constraints
• Product status may transition from obsolete to active

The SA101A911JAA meets all mandatory matching criteria while providing enhanced specifications in voltage rating (100V vs. 50V) and temperature coefficient stability (C0G/NP0 vs. C0H).

Parameter Comparison

Engineering Selection Recommendations

The SA101A911JAA from KYOCERA AVX serves as a direct functional substitute for the obsolete UP050CH911J-A-BZ. Selection of this substitute is supported by the following factors:

Product Status: The substitute part maintains active product status, ensuring long-term availability and manufacturing continuity compared to the obsolete main part.

Compliance Certifications: The SA101A911JAA carries ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements for electronic component procurement. Both parts share identical ECCN classification (EAR99).

Electrical Compatibility: The substitute provides identical capacitance (910 pF) and tolerance (±5%) with enhanced voltage rating (100V vs. 50V), permitting direct circuit substitution in applications originally specified for 50V operation.

Thermal Performance: The C0G/NP0 temperature coefficient of the substitute offers superior temperature stability compared to the C0H coefficient of the main part, with an extended operating range (-55°C ~ 125°C vs. -25°C ~ 85°C).

Physical Considerations: The substitute exhibits larger physical dimensions (0.100" Dia x 0.170" L vs. 0.087" Dia x 0.126" L). PCB layout verification is required to confirm accommodation of the increased package size within existing board space constraints.

Frequently Asked Questions (FAQ)

Q: Can the SA101A911JAA replace the UP050CH911J-A-BZ in existing designs?

A: Yes. Both parts share identical capacitance (910 pF), tolerance (±5%), mounting type (through hole), and package configuration (axial with straight leads). The substitute provides higher voltage rating (100V) and superior temperature coefficient stability (C0G/NP0), making it functionally compatible with circuits designed for the original part.

Q: What is the primary difference between these two parts?

A: The main differences are voltage rating (50V vs. 100V), temperature coefficient (C0H vs. C0G/NP0), operating temperature range (-25°C ~ 85°C vs. -55°C ~ 125°C), physical dimensions (0.087" Dia x 0.126" L vs. 0.100" Dia x 0.170" L), and product status (obsolete vs. active).

Q: Will the larger physical size of the SA101A911JAA cause PCB compatibility issues?

A: The substitute part is approximately 0.013" larger in diameter and 0.044" longer than the original part. PCB layout review is necessary to confirm that the increased dimensions do not interfere with adjacent components or violate board space constraints.

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

A: The SA101A911JAA carries ROHS3 compliance and REACH unaffected certification. Both parts share the same ECCN classification (EAR99). The substitute meets current regulatory requirements for electronic component procurement.

Q: What is the inventory status of each part?

A: The UP050CH911J-A-BZ (main part) has 1065 units in stock. The SA101A911JAA (substitute) has 784 units in stock. Both are available as new original components.

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

A: Yes. The SA101A911JAA operates across -55°C ~ 125°C, providing a wider temperature range than the original part (-25°C ~ 85°C). This makes it suitable for applications requiring extended thermal performance.
