Parameter Comparison

Engineering Selection Recommendations

The KTR10EZPF4703 from Rohm Semiconductor is a direct electrical and mechanical equivalent to the HV732ATTD4703F. Both parts are Active products with identical electrical specifications and package dimensions suitable for 0805 footprints.

The KTR10EZPF4703 carries AEC-Q200 automotive qualification, which represents an additional qualification level beyond the base specifications. This qualification does not restrict use in non-automotive applications and provides enhanced reliability documentation for applications requiring automotive-grade components.

Both parts maintain RoHS3 compliance, REACH Unaffected status, and MSL 1 rating, ensuring compatibility with modern manufacturing processes and environmental regulations. The maximum height difference of 0.002" (0.05mm) between the two parts is within standard PCB assembly tolerances and does not affect placement or functionality.

Selection between these parts should be based on availability, supply chain requirements, and any specific design qualifications already established for the application.

Frequently Asked Questions (FAQ)

Q: Can KTR10EZPF4703 be used as a direct replacement for HV732ATTD4703F?

A: Yes. Both parts share identical electrical specifications (470 kOhms ±1%, 0.125W, ±100ppm/°C), operate across the same temperature range (-55°C to 155°C), and use the same 0805 package. Physical dimensions are equivalent within manufacturing tolerances.

Q: What is the significance of the AEC-Q200 rating on the KTR10EZPF4703?

A: AEC-Q200 is an automotive qualification standard that certifies component reliability under automotive operating conditions. This qualification does not restrict the part to automotive use and indicates enhanced quality documentation and testing. Non-automotive applications may use this part without limitation.

Q: Are there any height compatibility issues between these parts?

A: The maximum seated height difference is 0.002" (0.05mm), which is within standard PCB assembly tolerances. Both parts are suitable for the same 0805 footprint without design modification.

Q: Do both parts meet current environmental compliance requirements?

A: Yes. Both HV732ATTD4703F and KTR10EZPF4703 are RoHS3 compliant, REACH Unaffected, and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting current manufacturing and environmental standards.

Q: What determines whether a substitute part is acceptable for this application?

A: Substitution is based on equivalence across resistance value, tolerance, power rating, temperature coefficient, operating temperature range, package type, and compliance certifications. All these parameters must match or exceed the original specification.
