Engineering Selection Recommendations

For applications requiring automotive AEC-Q200 qualification, select from: CRCW0603698KFKEA (Vishay Dale), ERJ-3EKF6983V (Panasonic), or RMCF0603FT698K (Stackpole Electronics). All three maintain active product status with robust inventory availability.

ERJ-3EKF6983V offers the highest inventory level (55622 Pcs) among AEC-Q200 qualified alternatives, supporting high-volume production requirements.

For non-automotive applications where AEC-Q200 qualification is not required, RC0603FR-07698KL (YAGEO) provides an active alternative with extensive inventory (30986 Pcs) and moisture-resistant thick film composition.

MCR03ERTF6983 (Rohm Semiconductor) is electrically equivalent but lacks AEC-Q200 certification and is discontinued, making it unsuitable for new designs despite available inventory.

All substitute parts maintain ROHS3 compliance, MSL 1 rating, and identical electrical performance within specified tolerances.

Frequently Asked Questions (FAQ)

Q: Can MCR03EZPFX6983 be replaced with any of the listed substitutes?

A: Yes, all listed parts meet the core electrical and mechanical parameters: 698 kOhms ±1%, 0.1W power rating, 0603 package, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Selection depends on specific application requirements, particularly automotive qualification needs.

Q: Which substitute is best for automotive applications?

A: CRCW0603698KFKEA, ERJ-3EKF6983V, and RMCF0603FT698K all carry AEC-Q200 qualification. ERJ-3EKF6983V is recommended for high-volume production due to superior inventory availability.

Q: Does package size differ between substitutes?

A: All substitutes use the 0603 (1608 Metric) package. Minor dimensional variations exist within standard tolerances (length 1.55mm to 1.60mm, width 0.80mm to 0.85mm, height 0.50mm to 0.55mm), but these do not affect PCB footprint compatibility.

Q: Is AEC-Q200 certification required for my application?

A: AEC-Q200 is mandatory for automotive and safety-critical applications. For industrial or consumer electronics, non-certified alternatives like RC0603FR-07698KL are acceptable if application specifications do not mandate automotive qualification.

Q: What is the difference between MCR03EZPFX6983 and MCR03ERTF6983?

A: Both are Rohm Semiconductor 698 kOhms ±1% 0.1W 0603 resistors with identical electrical specifications. MCR03EZPFX6983 includes AEC-Q200 qualification; MCR03ERTF6983 does not. Both are discontinued at DiGi Electronics.

Q: Can I use RC0603FR-07698KL in place of the original part?

A: RC0603FR-07698KL is electrically equivalent and meets all core parameters. However, it lacks AEC-Q200 certification. Use only if your application does not require automotive qualification. The part is active and widely available.

Q: What does MSL 1 (Unlimited) mean?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling, simplifying supply chain management.
