Engineering Selection Recommendations

Both the RP102PJ101CS and EXB-24V101JX are active production components with full RoHS3 compliance and MSL Level 1 rating, indicating unlimited shelf life under standard storage conditions.

The EXB-24V101JX qualifies as a direct electrical and mechanical substitute for the RP102PJ101CS. All critical parameters—resistance value, tolerance, power rating, temperature coefficient, circuit configuration, and package dimensions—are identical. The substitute part is available in Tape & Reel packaging format.

The operating temperature range of the EXB-24V101JX extends to -55°C ~ 125°C, which is 30°C lower than the RP102PJ101CS maximum of 155°C. For applications requiring operation above 125°C, the RP102PJ101CS is the appropriate selection. For applications within the -55°C ~ 125°C range, either part is suitable.

Both components are suitable for automotive applications where AEC-Q200 qualification is required, as indicated for the EXB-24V101JX.

Frequently Asked Questions (FAQ)

Q: Can the EXB-24V101JX replace the RP102PJ101CS in all applications?

A: The EXB-24V101JX is electrically and mechanically equivalent to the RP102PJ101CS for applications operating within -55°C to 125°C. Applications requiring operation above 125°C must use the RP102PJ101CS, which is rated to 155°C.

Q: Are the package footprints identical?

A: Yes. Both parts use the 0404 (1010 Metric) package with identical dimensions of 0.039" L x 0.039" W (1.00mm x 1.00mm) and maximum seated height of 0.018" (0.45mm). Direct PCB footprint compatibility is confirmed.

Q: What is the difference in packaging format?

A: The RP102PJ101CS is supplied in standard packaging format. The EXB-24V101JX is available in Tape & Reel (TR) format, which is standard for high-volume surface-mount assembly operations.

Q: Are both parts RoHS compliant?

A: Yes. Both the RP102PJ101CS and EXB-24V101JX are ROHS3 Compliant with REACH Unaffected status.

Q: What does MSL Level 1 mean for storage?

A: Moisture Sensitivity Level 1 indicates unlimited shelf life. These components do not require special moisture-controlled storage conditions and can be stored under standard warehouse conditions indefinitely.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes, within the operating temperature constraints noted above. Both parts have identical pin configurations, electrical specifications, and mechanical dimensions, enabling direct substitution on the same PCB design.
