UP050CH161J-A-BZ Equivalent & Substitute Parts

Part Overview

The UP050CH161J-A-BZ is a 160 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 procurement continuity. Substitute parts must maintain the same capacitance value and tolerance while accommodating the electrical and mechanical constraints of the original application.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UP050CH161J-A-BZ is determined by the following critical parameters:

Capacitance Match: All substitute parts must provide 160 pF capacitance with ±5% tolerance to ensure circuit functionality.

Voltage Rating Compatibility: Substitute parts must be rated at or above the original 50V specification. Higher voltage ratings provide design margin and are electrically compatible in applications requiring 50V operation.

Temperature Coefficient: The C0H temperature coefficient of the original part specifies predictable capacitance variation across temperature. Substitute parts with C0G/NP0 temperature coefficients provide superior stability and are functionally compatible, as C0G/NP0 represents a tighter specification subset.

Package and Mounting: Axial through-hole configuration with straight leads must be maintained for mechanical compatibility with existing printed circuit board layouts and assembly processes.

Moisture Sensitivity: MSL 1 rating indicates unlimited shelf life without moisture control, a non-restrictive specification that all substitutes must meet or exceed.

Parameter Comparison

Engineering Selection Recommendations

MA101A161JAA (KYOCERA AVX Ceralam® MA Series) qualifies as a direct substitute for the UP050CH161J-A-BZ based on the following criteria:

Electrical Compatibility: The MA101A161JAA maintains the required 160 pF capacitance at ±5% tolerance. The 100V voltage rating exceeds the original 50V specification, providing additional design margin without compromising circuit operation. The C0G/NP0 temperature coefficient offers superior temperature stability compared to the C0H specification of the original part.

Mechanical Compatibility: Both components utilize axial through-hole mounting with straight leads. Physical dimensions are comparable (0.090" diameter vs. 0.087" original; 0.160" length vs. 0.126" original), accommodating standard PCB layouts with minimal spacing adjustments.

Product Status and Availability: The MA101A161JAA is classified as active product with confirmed inventory availability (718 pcs), addressing the obsolescence of the original Taiyo Yuden component.

Compliance and Certifications: Both components carry EAR99 export classification and MSL 1 moisture sensitivity rating. The MA101A161JAA is RoHS non-compliant and REACH affected, consistent with the classification of legacy ceramic capacitor components.

Frequently Asked Questions (FAQ)

Q: Can the MA101A161JAA replace the UP050CH161J-A-BZ in existing designs?

A: Yes. The MA101A161JAA provides equivalent capacitance (160 pF ±5%) and maintains axial through-hole mounting compatibility. The higher voltage rating (100V vs. 50V) and superior temperature coefficient (C0G/NP0 vs. C0H) are compatible with applications designed for the original part.

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

A: Temperature coefficient defines capacitance variation across operating temperature. C0H specifies ±30 ppm/°C maximum variation, while C0G/NP0 specifies ±30 ppm/°C or tighter. The C0G/NP0 specification of the substitute part provides equal or superior temperature stability.

Q: Are there physical size differences that affect PCB layout?

A: The MA101A161JAA is slightly larger (0.090" diameter vs. 0.087"; 0.160" length vs. 0.126"). Standard PCB designs accommodate this minor dimensional variance. Verify lead spacing and component clearance in confined layouts.

Q: Does the higher voltage rating of the substitute part affect circuit performance?

A: No. A 100V-rated capacitor operates correctly in 50V applications. Higher voltage ratings provide design margin and do not alter capacitance or frequency response characteristics.

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

A: The MA101A161JAA is currently in active production with 718 pcs available in stock, ensuring procurement continuity for the obsolete UP050CH161J-A-BZ.

Q: Are there compliance or regulatory differences between the original and substitute parts?

A: Both components carry EAR99 export classification and MSL 1 moisture sensitivity rating. The MA101A161JAA is RoHS non-compliant and REACH affected, consistent with legacy ceramic capacitor classifications.
