Engineering Selection Recommendations

RR01J240RTB Selection Criteria: The TE Connectivity RR01J240RTB is the primary component specification. This part supports extended operating temperature range to 235°C and includes pulse withstanding capability. Selection of this part is appropriate for applications requiring maximum thermal performance within the 240 Ohm, 1W, ±5% tolerance specification.

PR01000102400JR500 Selection Criteria: The Vishay Beyschlag PR01000102400JR500 serves as an equivalent substitute for applications where the extended upper temperature limit of the main part is not required. This substitute part includes Automotive AEC-Q200 qualification and fusible characteristics. The operating temperature range of -55°C to 155°C is suitable for standard industrial and commercial applications. The superior temperature coefficient (±250ppm/°C versus ±300ppm/°C) provides improved stability characteristics.

Both parts maintain RoHS3 compliance and REACH unaffected status. Both are classified as Active products with equivalent electrical specifications and axial through-hole mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can PR01000102400JR500 replace RR01J240RTB in all applications?

A: Electrical and mechanical compatibility is confirmed. The substitute part operates to 155°C maximum, compared to 235°C for the main part. Applications requiring operation above 155°C require the RR01J240RTB. Applications within the -55°C to 155°C range accept the substitute part.

Q: What is the physical size difference between these parts?

A: RR01J240RTB dimensions are 0.102" diameter by 0.268" length (2.60mm x 6.80mm). PR01000102400JR500 dimensions are 0.098" diameter by 0.256" length (2.50mm x 6.50mm). Both are axial through-hole components with compatible PCB mounting footprints. The substitute part is slightly smaller.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RR01J240RTB and PR01000102400JR500 are RoHS3 compliant and REACH unaffected.

Q: What is the significance of the temperature coefficient difference?

A: RR01J240RTB has a temperature coefficient of ±300ppm/°C. PR01000102400JR500 has a temperature coefficient of ±250ppm/°C. The substitute part exhibits superior temperature stability, meaning resistance value changes less with temperature variation.

Q: Does PR01000102400JR500 include automotive qualification?

A: Yes. PR01000102400JR500 includes Automotive AEC-Q200 qualification. RR01J240RTB specifications do not indicate automotive qualification.

Q: Are both parts available in Cut Tape packaging?

A: Yes. Both RR01J240RTB and PR01000102400JR500 are supplied in Cut Tape (CT) packaging format.

Q: What does "fusible" mean for the substitute part?

A: The PR01000102400JR500 includes fusible characteristics, meaning the resistor element will open circuit under excessive current conditions. This feature is not specified for the RR01J240RTB.
