Frequently Asked Questions (FAQ)

Q: Can RN73R2ATTD3012D50 be used as a direct replacement for RN732ATTD3012D50 without circuit modifications?

A: Yes. The RN73R2ATTD3012D50 is electrically and mechanically equivalent. Identical resistance (30.1 kOhms), tolerance (±0.5%), temperature coefficient (±50ppm/°C), and package dimensions (0805, 2.00mm x 1.25mm) ensure drop-in compatibility. No circuit design changes are required.

Q: What is the difference in power rating between these two parts?

A: The RN732ATTD3012D50 is rated at 0.1W (1/10W), while the RN73R2ATTD3012D50 is rated at 0.125W (1/8W). The substitute part has 25% higher power dissipation capacity. This difference does not affect compatibility; the higher rating provides additional thermal margin.

Q: Are both parts available in the same packaging format?

A: Both components use 0805 (2012 Metric) package with identical physical dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm) and maximum seated height of 0.024" (0.60mm). They are mechanically interchangeable on PCBs designed for 0805 resistors.

Q: What is the significance of the Obsolete status for RN732ATTD3012D50?

A: Obsolete status indicates that the RN732ATTD3012D50 is no longer in active production. The RN73R2ATTD3012D50 maintains Active status, ensuring continued manufacturing, availability, and technical support from KOA Speer Electronics, Inc.

Q: Does the AEC-Q200 certification on RN73R2ATTD3012D50 affect its use in non-automotive applications?

A: No. AEC-Q200 certification represents an additional qualification standard. The RN73R2ATTD3012D50 is suitable for all applications, including non-automotive designs. The certification does not restrict its use.

Q: Are the RoHS and REACH compliance statuses identical for both parts?

A: Yes. Both RN732ATTD3012D50 and RN73R2ATTD3012D50 are ROHS3 Compliant and REACH Unaffected, with identical Moisture Sensitivity Level (MSL) of 1 (Unlimited). Regulatory compliance is maintained across the substitution.
