UP050CH751J-A-BZ Equivalent & Substitute Parts

Part Overview

The UP050CH751J-A-BZ is a 750 pF ceramic capacitor rated at 50V with C0H temperature coefficient, manufactured by Taiyo Yuden in axial through-hole configuration. This part is classified as obsolete, necessitating identification of functionally equivalent alternatives for ongoing design support and procurement continuity. The part maintains 1141 units in current inventory stock.

Substitute parts must satisfy the core electrical parameters: 750 pF capacitance value, ±5% tolerance, and axial through-hole mounting. Voltage rating and temperature coefficient may vary within acceptable design margins depending on application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following mandatory parameters:

Core Electrical Parameters (Must Match):

• Capacitance value: 750 pF
• Tolerance: ±5%
• Mounting type: Through Hole
• Package type: Axial

Flexible Parameters (May Vary):

• Voltage rating: Substitute must equal or exceed 50V
• Temperature coefficient: C0G/NP0 acceptable as higher-stability alternative to C0H
• Operating temperature range: Substitute may exceed original range
• Physical dimensions: Axial package allows minor dimensional variation
• Product status: Active status preferred for long-term availability

The SA101A751JAA from KYOCERA AVX meets all core electrical requirements and provides enhanced specifications in voltage rating (100V) and temperature stability (C0G/NP0 with -55°C ~ 125°C range).

Parameter Comparison

Engineering Selection Recommendations

SA101A751JAA Selection Basis:

The SA101A751JAA qualifies as a direct substitute based on matching core electrical specifications (750 pF, ±5%, axial through-hole configuration). The substitute provides superior performance characteristics:

• Voltage Rating Enhancement: 100V rating provides 2× margin over the original 50V specification, suitable for applications with voltage transient protection requirements.
• Temperature Coefficient Upgrade: C0G/NP0 classification delivers superior temperature stability compared to C0H, reducing capacitance drift across the operating range.
• Extended Operating Range: -55°C ~ 125°C accommodates broader environmental conditions than the original -25°C ~ 85°C specification.
• Product Status: Active manufacturing status ensures long-term availability and supply chain continuity, addressing the obsolescence of the original part.
• Regulatory Compliance: ROHS3 compliance and REACH unaffected status satisfy current environmental and regulatory requirements.

Physical Compatibility Consideration:

The SA101A751JAA exhibits larger physical dimensions (0.100" Dia x 0.170" L versus 0.087" Dia x 0.126" L). PCB layout verification is required to confirm clearance in existing designs. Axial lead spacing and straight lead style remain compatible with through-hole mounting infrastructure.

Frequently Asked Questions (FAQ)

Q: Can SA101A751JAA directly replace UP050CH751J-A-BZ in existing designs?

A: Electrical substitution is valid. The 750 pF capacitance, ±5% tolerance, and axial through-hole mounting are identical. Physical board layout must accommodate the larger package dimensions (0.100" Dia x 0.170" L). Verify clearance around component mounting location before implementation.

Q: What is the significance of the voltage rating difference (50V vs. 100V)?

A: The substitute's 100V rating provides additional safety margin and transient protection. In applications operating at or below 50V, the higher rating does not degrade performance. The substitute is suitable for all applications where the original 50V part was specified.

Q: How does the temperature coefficient change affect circuit performance?

A: C0G/NP0 temperature coefficient provides superior stability compared to C0H across temperature variations. Capacitance drift is reduced, resulting in more predictable circuit behavior in temperature-sensitive applications. This represents an improvement over the original specification.

Q: Are there lead spacing or mounting compatibility issues?

A: Both parts feature straight leads in axial configuration suitable for through-hole mounting. Lead spacing is not specified for either part. Physical dimensions differ; verify PCB hole spacing and component clearance accommodate the substitute's larger body diameter and length.

Q: What is the impact of the larger physical size?

A: The SA101A751JAA is physically larger (0.100" Dia x 0.170" L) compared to the original (0.087" Dia x 0.126" L). This may affect PCB layout in space-constrained designs. Confirm available board space and clearance to adjacent components before selection.

Q: Does the substitute meet current regulatory requirements?

A: Yes. The SA101A751JAA is ROHS3 compliant and REACH unaffected, satisfying current environmental regulations. The original part's regulatory status is not specified.

Q: Is the substitute available in equivalent inventory quantities?

A: The SA101A751JAA has 950 units in current stock, compared to 1141 units of the original part. Both quantities support immediate procurement.
