Engineering Selection Recommendations
The ECS-P145-BX serves as a direct electrical and mechanical equivalent to the ECS-P145-B. Both components are manufactured by ECS Inc. and share identical specifications across all critical operating parameters, package dimensions, and environmental ratings.
A key distinction exists in RoHS compliance status. The ECS-P145-B is RoHS non-compliant, while the ECS-P145-BX is ROHS3 compliant. This difference is significant for applications subject to RoHS directives or procurement policies requiring RoHS-compliant components. Both parts maintain identical REACH and ECCN classifications.
Selection between these two parts should be based on the specific compliance requirements of the target application and end-use market. The ECS-P145-BX is the appropriate choice for designs requiring RoHS3 compliance. The ECS-P145-B remains suitable for applications without RoHS compliance mandates. Both parts are active products with adequate inventory availability.
Frequently Asked Questions (FAQ)
Q: Can the ECS-P145-BX be used as a direct replacement for the ECS-P145-B in existing designs?
A: Yes. The ECS-P145-BX is electrically and mechanically equivalent to the ECS-P145-B. All operating parameters, frequency ranges, output characteristics, supply voltage requirements, and package dimensions are identical. Pin-for-pin compatibility is maintained.
Q: What is the primary difference between these two parts?
A: The primary difference is RoHS compliance status. The ECS-P145-B is RoHS non-compliant, while the ECS-P145-BX is ROHS3 compliant. All other electrical, mechanical, and environmental specifications are identical.
Q: Are there any frequency limitations when substituting between these parts?
A: No. Both parts support the identical frequency range of 1 MHz to 150 MHz. Frequency selection is determined by the programmable configuration ordered through DiGi Electronics and does not vary between the two part numbers.
Q: Do these parts have different package dimensions or mounting requirements?
A: No. Both the ECS-P145-B and ECS-P145-BX use the same 14-DIP, 4-lead full-size metal can package with through-hole mounting. Physical dimensions, seated height, and PCB footprint requirements are identical.
Q: Which part should be selected for new designs?
A: For new designs, the ECS-P145-BX is the recommended choice due to its ROHS3 compliance status, which aligns with current regulatory requirements and industry standards. The ECS-P145-B remains suitable for legacy designs or applications without RoHS compliance mandates.
Q: Are the supply current specifications identical between these parts?
A: Yes. Both parts have a maximum supply current specification of 45mA at 5V supply voltage. Operating current characteristics are identical.
Q: Do these parts have different temperature operating ranges?
A: No. Both parts operate across the identical temperature range of 0°C to 70°C with the same frequency stability specification of ±50ppm across this range.
