Parameter Comparison

Engineering Selection Recommendations

Primary Selection (New Designs): ERJ-S1DF8251U remains the recommended choice for new designs. It is in active production status, ROHS3 compliant, and includes anti-sulfur coating for enhanced reliability in harsh automotive environments.

Alternative Selection (Active Status): CRCW20108K25FKEF from Vishay Dale is an active alternative that meets all electrical and mechanical parameters. It is ROHS3 compliant and AEC-Q200 qualified. This part is suitable for new designs and offers cross-manufacturer sourcing flexibility.

Legacy / Inventory Clearance Only: ERJ-12SF8251U is marked as "Not For New Designs" and is RoHS non-compliant. This part should be used only for legacy system maintenance or existing design revisions where regulatory compliance is not a requirement.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF8251U be used as a direct replacement in new automotive designs? A: No. ERJ-12SF8251U is designated "Not For New Designs" and does not meet ROHS3 compliance requirements. It is suitable only for legacy system support or design revisions where RoHS compliance is not mandated.

Q: Are all three parts electrically identical? A: Yes. All three parts share identical electrical specifications: 8.25 kOhms ±1%, 0.75W power rating, ±100ppm/°C temperature coefficient, and -55°C ~ 155°C operating range. All are AEC-Q200 qualified thick film resistors.

Q: What is the difference between Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging? A: Both packaging formats contain the same component. Tape & Reel is supplied on continuous tape for automated assembly. Cut Tape & Digi-Reel® offers smaller quantity options with reel compatibility. Selection depends on production volume and assembly equipment requirements.

Q: Can CRCW20108K25FKEF replace ERJ-S1DF8251U in existing designs? A: Yes. CRCW20108K25FKEF meets all electrical, mechanical, and functional parameters. Both parts are active, ROHS3 compliant, and AEC-Q200 qualified. The primary difference is manufacturer (Vishay Dale vs. Panasonic).

Q: What does MSL 1 (Unlimited) mean for these resistors? A: MSL 1 indicates the lowest moisture sensitivity level. These parts have unlimited shelf life under normal storage conditions and do not require special moisture control during handling or storage.

Q: Are these parts suitable for automotive applications? A: Yes. All three parts carry AEC-Q200 automotive qualification, indicating they meet automotive industry reliability and performance standards. ERJ-S1DF8251U includes additional anti-sulfur coating for enhanced corrosion resistance.
