Engineering Selection Recommendations

Both substitute parts maintain full electrical and mechanical compatibility with the CAY10-470J2LF. Selection between alternatives is based on the following factors:

EXB-24V470JX (Panasonic Electronic Components) is qualified for Automotive AEC-Q200 applications and offers improved temperature coefficient performance (±200ppm/°C versus ±250ppm/°C). This part is suitable for applications requiring automotive-grade reliability.

RAVF102DJT47R0 (Stackpole Electronics Inc) is also Automotive AEC-Q200 qualified and extends the operating temperature range to -55°C ~ 155°C, providing additional thermal margin. This part is appropriate for high-temperature environments within the automotive sector.

All three parts maintain Active product status, RoHS3 compliance, and MSL 1 rating. Component selection should be based on application-specific temperature requirements, supply chain availability, and automotive qualification needs.

Frequently Asked Questions (FAQ)

Q: Can EXB-24V470JX replace CAY10-470J2LF in existing designs?

A: Yes. Both parts share identical resistance value (47 Ohm), tolerance (±5%), circuit configuration (isolated 2-resistor network), power rating (62.5mW per element), package type (0404 1010 Metric), and pin count (4). Physical dimensions and mounting characteristics are equivalent.

Q: What is the difference in temperature coefficient between the parts?

A: CAY10-470J2LF has a temperature coefficient of ±250ppm/°C, while EXB-24V470JX and RAVF102DJT47R0 both specify ±200ppm/°C. The substitute parts offer tighter temperature stability.

Q: Does RAVF102DJT47R0 provide advantages for high-temperature applications?

A: RAVF102DJT47R0 extends the maximum operating temperature to 155°C compared to 125°C for the original part. This provides additional thermal headroom for applications operating near upper temperature limits.

Q: Are all three parts suitable for automotive applications?

A: CAY10-470J2LF is Active status with RoHS3 compliance but does not specify automotive qualification. EXB-24V470JX and RAVF102DJT47R0 both carry AEC-Q200 automotive qualification, making them preferred for automotive designs.

Q: Is PCB layout modification required when substituting these parts?

A: No. All three parts use identical 0404 (1010 Metric) package dimensions and 4-pin configuration. PCB footprints are directly compatible without layout changes.

Q: What is the moisture sensitivity rating for all parts?

A: All three parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.
