Frequently Asked Questions (FAQ)

Q: Can PR01000102009JR500 be used as a direct replacement for RR01J20RTB?

A: The PR01000102009JR500 is electrically and mechanically equivalent to the RR01J20RTB for applications operating within the -55°C to 155°C temperature range. Both components share identical resistance (20 Ohms), tolerance (±5%), power rating (1W), composition (metal film), and axial package configuration. Physical dimensions are similar with minor variations. Both are RoHS3 compliant and REACH unaffected.

Q: What is the difference in operating temperature range between these components?

A: The RR01J20RTB operates from -55°C to 235°C, while the PR01000102009JR500 operates from -55°C to 155°C. Applications requiring operation above 155°C must use the RR01J20RTB. Applications operating within the -55°C to 155°C range can use either component.

Q: Are there physical dimension differences between these resistors?

A: The RR01J20RTB measures 0.102" diameter by 0.268" length (2.60mm x 6.80mm). The PR01000102009JR500 measures 0.098" diameter by 0.256" length (2.50mm x 6.50mm). Both are axial through-hole components with two terminations. The dimensional difference is approximately 2-4% and does not affect standard PCB footprint compatibility for axial resistor layouts.

Q: What additional features does the substitute part offer?

A: The PR01000102009JR500 includes automotive AEC-Q200 qualification and fusible characteristics. The substitute also features a superior temperature coefficient of ±250ppm/°C compared to the main part's ±300ppm/°C, providing better stability across temperature variations.
