UP050CH111J-A-BZ Equivalent & Substitute Parts

Part Overview

The UP050CH111J-A-BZ is a 110 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. Substitute parts must maintain the same capacitance value, voltage rating, and tolerance while accommodating different mounting technologies and temperature coefficient specifications where applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the UP050CH111J-A-BZ is determined by the following critical parameters: capacitance value (110 pF), tolerance (±5%), and voltage rating (50V). These three parameters define functional equivalence in ceramic capacitor applications.

The identified substitute parts are grouped into two categories based on mounting technology:

Through-Hole Radial Configuration: The SR151A111JAA maintains through-hole mounting compatibility with the original part while providing enhanced voltage rating (100V) and improved temperature stability through C0G/NP0 temperature coefficient. This part is suitable for direct replacement in applications where the original axial configuration can accommodate radial geometry.

Surface-Mount Configuration: The CL21C111JBANNNC provides the same electrical specifications in a modern surface-mount 0805 package. This substitute is applicable for new designs or board redesigns incorporating surface-mount technology.

All substitute parts maintain the required 110 pF capacitance, ±5% tolerance, and minimum 50V voltage rating. Temperature coefficient variations (C0G/NP0 versus C0H) represent improvements in temperature stability and are acceptable substitutions for general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

For Through-Hole Applications: The SR151A111JAA is the direct functional equivalent for through-hole mounting requirements. This part is actively manufactured and carries ROHS3 compliance certification. The elevated voltage rating (100V versus 50V) provides additional design margin without affecting circuit performance in 50V applications. The C0G/NP0 temperature coefficient offers superior temperature stability compared to the original C0H specification, extending the operating temperature range to -55°C ~ 125°C.

For Surface-Mount Applications: The CL21C111JBANNNC accommodates designs utilizing surface-mount technology. This part maintains the 50V voltage rating and ±5% tolerance specification. ROHS3 compliance and REACH unaffected status confirm regulatory alignment with current manufacturing standards.

Procurement Considerations: Both substitute parts are currently in active production with confirmed inventory availability. The SR151A111JAA offers 626 units in stock, while the CL21C111JBANNNC provides 1004 units. Selection between these options depends on circuit board design requirements and mounting technology constraints.

Frequently Asked Questions (FAQ)

Q: Can the SR151A111JAA replace the UP050CH111J-A-BZ in existing designs?

A: Yes. The SR151A111JAA maintains electrical equivalence through identical capacitance (110 pF), tolerance (±5%), and exceeds the voltage requirement (100V rating versus 50V). Both parts are through-hole mounted. Physical dimensions differ due to radial versus axial configuration; board layout verification is required to confirm mechanical fit.

Q: What is the difference between C0H and C0G/NP0 temperature coefficients?

A: C0H and C0G/NP0 are both temperature coefficient classifications for ceramic capacitors. C0G/NP0 provides tighter temperature stability specifications and is preferred for precision applications. Both are acceptable for general-purpose applications. The substitute parts with C0G/NP0 coefficients represent an improvement over the original C0H specification.

Q: Is the CL21C111JBANNNC suitable for direct board replacement?

A: The CL21C111JBANNNC is electrically equivalent but requires board redesign due to different mounting technology (surface-mount 0805 versus through-hole axial). This part is applicable for new designs or planned board revisions incorporating surface-mount components.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both SR151A111JAA and CL21C111JBANNNC carry ROHS3 compliance certification, meeting current environmental and regulatory requirements.

Q: What is the voltage derating consideration for the SR151A111JAA?

A: The SR151A111JAA is rated at 100V, which exceeds the original 50V requirement. Operating this part at 50V represents conservative design practice with increased reliability margin. No derating adjustment is necessary.

Q: Can both substitute parts be used interchangeably in the same application?

A: Electrical interchangeability is confirmed; however, mounting technology differs. Selection depends on circuit board design: the SR151A111JAA for through-hole applications and the CL21C111JBANNNC for surface-mount applications. Both maintain the required 110 pF capacitance and ±5% tolerance.
