Engineering Selection Recommendations

All three parts maintain active production status and full RoHS3 compliance. The EXB-38V204JV and CAY16-204J4LF are electrically and mechanically identical across all specified parameters, with maximum seated heights of 0.024" (0.60mm).

The YC164-JR-07200KL from YAGEO provides an extended operating temperature range of -55°C to 155°C compared to the -55°C to 125°C range of the primary part, with AEC-Q200 automotive qualification explicitly stated. The maximum seated height of this part is 0.028" (0.70mm), which represents a 0.004" (0.10mm) increase. This height differential must be evaluated against specific PCB assembly constraints and clearance requirements in the target application.

Selection between these substitutes should be based on supply availability, lead time requirements, and application-specific thermal operating conditions. All parts satisfy the core electrical specifications and compliance requirements for standard industrial and automotive applications within the -55°C to 125°C range.

Frequently Asked Questions (FAQ)

Q: Can CAY16-204J4LF be used as a direct replacement for EXB-38V204JV?

A: Yes. Both parts are electrically and mechanically identical across all specified parameters, including resistance value, tolerance, power rating, temperature coefficient, package dimensions, and height. No design modifications are required for direct substitution.

Q: What is the key difference between YC164-JR-07200KL and the other two parts?

A: The YC164-JR-07200KL has an extended operating temperature range of -55°C to 155°C versus -55°C to 125°C for the EXB-38V204JV and CAY16-204J4LF. Additionally, the maximum seated height is 0.028" (0.70mm) compared to 0.024" (0.60mm) for the other parts. All other electrical and mechanical parameters are identical.

Q: Is the 0.004" height difference between YC164-JR-07200KL and the other parts significant?

A: The height difference must be evaluated against specific PCB assembly clearance requirements. For applications with tight vertical constraints or specific solder reflow profiles, this difference should be confirmed with manufacturing and design teams.

Q: Are all three parts suitable for automotive applications?

A: The EXB-38V204JV and YC164-JR-07200KL carry explicit AEC-Q200 automotive qualification. The CAY16-204J4LF does not list automotive applications in the provided specifications. Application suitability should be confirmed based on specific automotive requirements.
