Engineering Selection Recommendations

Both YC124-JR-073KL and EXB-28V302JX are Active products with ROHS3 compliance and MSL 1 ratings. The EXB-28V302JX operates within a reduced upper temperature limit of 125°C compared to the YC124-JR-073KL at 155°C. The seated height of the EXB-28V302JX is 0.018" (0.45mm) versus 0.022" (0.55mm) for the YAGEO part. Selection between these components depends on application-specific thermal requirements and PCB clearance constraints. Both components are qualified for automotive applications under AEC-Q200 standards.

Frequently Asked Questions (FAQ)

Q: Can EXB-28V302JX replace YC124-JR-073KL in all applications?

A: Direct substitution is valid for applications operating within -55°C to 125°C. Applications requiring operation above 125°C require the YC124-JR-073KL.

Q: Are there mechanical compatibility concerns between these parts?

A: Both components use identical 0804 package dimensions (0.079" L x 0.039" W). The EXB-28V302JX has a lower seated height (0.018" vs 0.022"), which may provide additional PCB clearance in space-constrained designs.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both YC124-JR-073KL and EXB-28V302JX carry AEC-Q200 automotive qualification and ROHS3 compliance.

Q: What are the electrical equivalencies between these parts?

A: Both components provide identical electrical specifications: 3kΩ ±5% tolerance, 62.5mW power per element, ±200ppm/°C temperature coefficient, and isolated 4-resistor network configuration with 8 pins.

Q: Are moisture sensitivity levels equivalent?

A: Yes. Both parts are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.
