Frequently Asked Questions (FAQ)

Q: Can the RN73R2ATTD2203C25 be used as a direct replacement for the RN732ATTD2203C25?

A: Yes. The RN73R2ATTD2203C25 is electrically and mechanically equivalent. Both parts share identical resistance (220 kOhms), tolerance (±0.25%), package format (0805), and operating temperature range (-55°C ~ 155°C). The substitute part is pin-compatible and footprint-compatible with the original part.

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

A: The RN732ATTD2203C25 is rated for 0.1W (1/10W) power dissipation, while the RN73R2ATTD2203C25 is rated for 0.125W (1/8W). The higher power rating of the substitute part does not affect circuit operation and provides additional thermal headroom in applications operating near the original part's power limit.

Q: Are there packaging differences between these parts?

A: Both parts are supplied in the 0805 (2012 Metric) package with identical physical dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm) and maximum seated height (0.024", 0.60mm). The RN73R2ATTD2203C25 is available in Tape & Reel (TR) packaging, while the RN732ATTD2203C25 packaging format is not specified in the provided data.

Q: What is the significance of the AEC-Q200 qualification on the substitute part?

A: AEC-Q200 is an automotive industry qualification standard indicating that the RN73R2ATTD2203C25 has undergone enhanced reliability testing and process validation. This certification does not restrict use in non-automotive applications and indicates higher manufacturing process controls.

Q: Are both parts RoHS compliant?

A: Yes. Both the RN732ATTD2203C25 and RN73R2ATTD2203C25 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Why is the main part listed as obsolete?

A: The RN732ATTD2203C25 carries obsolete product status, indicating that the manufacturer has discontinued active production and support. The RN73R2ATTD2203C25 maintains active status, ensuring continued availability and supply chain support for new designs and ongoing production requirements.
