Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the UP050CH511J-B-BZ is determined by the following criteria:

Mandatory Matching Parameters:

• Capacitance value: 510 pF (exact match required)
• Tolerance: ±5% or tighter
• Mounting type: Through Hole
• Package type: Axial
• Lead style: Straight

Allowable Upgrade Parameters:

• Voltage rating: Equal to or greater than 50V
• Operating temperature range: Must encompass or exceed -25°C to 85°C
• Temperature coefficient: C0G/NP0 acceptable as equivalent or superior to C0H

The SA101A511JAR meets all mandatory parameters while providing enhanced voltage rating (100V vs. 50V) and extended operating temperature range (-55°C to 125°C vs. -25°C to 85°C). The temperature coefficient upgrade from C0H to C0G/NP0 represents improved thermal stability characteristics.

Parameter Comparison

Engineering Selection Recommendations

SA101A511JAR Selection Basis:

The SA101A511JAR qualifies as a direct substitute based on electrical parameter equivalence and regulatory compliance advantages. The part maintains identical capacitance (510 pF) and tolerance (±5%) specifications while providing enhanced voltage margin (100V vs. 50V) and extended temperature operating range (-55°C to 125°C vs. -25°C to 85°C).

The substitute part carries Active product status, ensuring long-term availability and supply chain continuity compared to the Obsolete classification of the original part. ROHS3 compliance and REACH Unaffected status provide regulatory alignment for current manufacturing standards.

Physical dimensions increase from 0.087" to 0.100" diameter and 0.126" to 0.170" length. PCB layout verification is required to confirm accommodation of the larger axial package footprint. Lead spacing and straight lead configuration remain compatible with through-hole assembly processes.

The temperature coefficient upgrade from C0H to C0G/NP0 delivers superior frequency stability and reduced capacitance drift across the operating temperature spectrum, representing a performance enhancement for general-purpose applications.

Frequently Asked Questions (FAQ)

Q: Can the SA101A511JAR directly replace the UP050CH511J-B-BZ in existing designs?

A: Electrical substitution is valid based on matching capacitance, tolerance, and voltage rating specifications. Physical PCB layout verification is mandatory due to increased component dimensions (0.100" vs. 0.087" diameter; 0.170" vs. 0.126" length). Confirm available board space accommodates the larger axial package before implementation.

Q: What is the significance of the voltage rating increase from 50V to 100V?

A: The higher voltage rating provides additional safety margin and operational headroom in the circuit. This upgrade does not alter the capacitor's electrical behavior at the original 50V operating point and is considered a beneficial parameter enhancement for reliability.

Q: How does the temperature coefficient change from C0H to C0G/NP0 affect circuit performance?

A: C0G/NP0 represents a superior temperature stability classification with reduced capacitance variation across temperature extremes. This upgrade improves frequency stability and reduces temperature-induced drift, particularly beneficial for precision timing and filtering applications.

Q: Are there packaging differences between the main part and substitute?

A: The main part ships in standard packaging while the substitute (SA101A511JAR) is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and does not affect component electrical or mechanical specifications.

Q: What compliance advantages does the substitute part provide?

A: The SA101A511JAR carries ROHS3 Compliant and REACH Unaffected certifications, aligning with current environmental and regulatory requirements. The original part's compliance status is not specified, making the substitute preferable for new designs and manufacturing environments with strict regulatory requirements.

Q: Is the increased physical size a concern for PCB integration?

A: Physical size increase must be evaluated against available PCB real estate. The axial lead configuration and straight lead style remain unchanged, maintaining compatibility with through-hole assembly. Measure available board space to confirm the larger diameter (0.100" vs. 0.087") and length (0.170" vs. 0.126") fit within design constraints.

Q: Does the Active product status of the substitute provide supply advantages?

A: Active product status indicates ongoing manufacturing and distribution support. The original part's Obsolete classification creates long-term procurement risk. The substitute's Active status ensures sustained availability and supply chain reliability for current and future production requirements.
