Key Parameters

Substitute Part Grouping Explanation

Substitution of the UP050CH511J-A-BZ is determined by the following critical parameters that must remain constant or exceed the original specification:

Mandatory Matching Parameters:

• Capacitance value: 510 pF
• Tolerance: ±5%
• Mounting type: Through Hole
• Package type: Axial
• Lead style: Straight

Allowable Parameter Variations:

• Voltage rating: Substitute must equal or exceed 50V
• Temperature coefficient: Substitute with C0G/NP0 (superior stability) is acceptable
• Operating temperature range: Substitute must encompass or exceed -25°C ~ 85°C
• Physical dimensions: Substitute may differ if board layout permits
• Product status: Active status preferred for long-term availability

The SA101A511JAR from KYOCERA AVX meets all mandatory parameters while providing enhanced electrical characteristics through higher voltage rating (100V) and superior temperature coefficient stability (C0G/NP0).

Engineering Selection Recommendations

The SA101A511JAR serves as a direct functional substitute for the obsolete UP050CH511J-A-BZ based on the following engineering criteria:

Electrical Compatibility: Both components maintain identical 510 pF capacitance and ±5% tolerance specifications. The substitute's 100V voltage rating provides 2x margin over the original 50V specification, enhancing circuit reliability. The C0G/NP0 temperature coefficient of the substitute offers superior temperature stability compared to the original C0H coefficient.

Thermal Performance: The substitute's -55°C ~ 125°C operating range encompasses the original -25°C ~ 85°C specification, providing extended operational capability across broader environmental conditions.

Mechanical Compatibility: Both components feature axial through-hole mounting with straight leads. The substitute exhibits slightly larger physical dimensions (0.100" Dia x 0.170" L versus 0.087" Dia x 0.126" L), requiring verification of available board space during integration.

Regulatory Compliance: The substitute carries ROHS3 compliance and REACH unaffected status, meeting current environmental and regulatory requirements. Both components share EAR99 export classification.

Product Availability: The substitute maintains active product status with established supply chain availability, eliminating obsolescence risk associated with the original component.

Frequently Asked Questions (FAQ)

Q: Can the SA101A511JAR directly replace the UP050CH511J-A-BZ without circuit modification?

A: Yes, the substitute maintains identical capacitance (510 pF) and tolerance (±5%) specifications. The higher voltage rating (100V versus 50V) and superior temperature coefficient (C0G/NP0 versus C0H) present no compatibility issues. Physical dimension differences require board layout verification.

Q: What is the significance of the temperature coefficient difference between C0H and C0G/NP0?

A: C0G/NP0 temperature coefficient provides superior stability with minimal capacitance variation across temperature extremes. C0H exhibits greater capacitance drift with temperature. The substitute's C0G/NP0 specification enhances circuit performance stability, particularly in temperature-sensitive applications.

Q: Does the larger physical size of the substitute present integration challenges?

A: The substitute measures 0.100" Dia x 0.170" L compared to the original 0.087" Dia x 0.126" L. Verification of available board space and lead hole spacing is required prior to implementation. Both components maintain straight lead configuration and through-hole mounting compatibility.

Q: What packaging format differences exist between these components?

A: The original UP050CH511J-A-BZ ships in bulk packaging. The substitute SA101A511JAR is supplied in Tape & Reel (TR) format, standard for automated assembly processes. This difference affects procurement and handling procedures but does not impact electrical or mechanical performance.

Q: Are there regulatory or compliance advantages to selecting the substitute?

A: The substitute carries explicit ROHS3 compliance and REACH unaffected certification. These certifications ensure compliance with current environmental regulations and support supply chain requirements for regulated markets. Both components share identical EAR99 export classification.

Q: What inventory considerations apply to this substitution?

A: The original component is classified as obsolete with limited remaining stock (947 Pcs). The substitute maintains active product status with established supply availability (980 Pcs in stock), ensuring long-term procurement continuity and design support.
