Substitute Part Grouping Explanation

Substitute parts for the ERJ-S1DF2870U are qualified based on the following criteria:

• Resistance value: 287 Ohms
• Tolerance: ±1%
• Power rating: 0.75W (3/4W)
• Package: 2010 (5025 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

All identified substitutes match these parameters across different manufacturers, ensuring electrical and mechanical compatibility for direct board-level replacement.

Parameter Comparison

Engineering Selection Recommendations

For new designs, the ERJ-S1DF2870U (Panasonic, Active status) and CRCW2010287RFKEF (Vishay Dale, Active status) are the preferred selections due to their active production status and full compliance with ROHS3 and AEC-Q200 automotive standards.

The ERJ-12SF2870U (Panasonic) is electrically and mechanically equivalent but carries a "Not For New Designs" status, making it suitable only for legacy system maintenance or replacement applications where design continuity is required.

All three parts meet identical electrical specifications, dimensional requirements, and automotive qualification criteria, ensuring functional interchangeability in circuit applications requiring 287 Ohms ±1% 0.75W thick film resistors in 2010 package format.

Frequently Asked Questions (FAQ)

Q: Can ERJ-12SF2870U be used in new designs? A: The ERJ-12SF2870U carries a "Not For New Designs" status. For new circuit designs, use ERJ-S1DF2870U or CRCW2010287RFKEF, both in active production.

Q: Are all three parts mechanically identical? A: Yes. All parts share identical dimensions (0.197" L x 0.098" W, 5.00mm x 2.50mm) and maximum seated height (0.028", 0.70mm), ensuring direct PCB footprint compatibility.

Q: What electrical parameters must match for substitution? A: Resistance (287 Ohms), tolerance (±1%), power rating (0.75W), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C) must all match for functional equivalence.

Q: Are these parts suitable for automotive applications? A: Yes. All three parts carry AEC-Q200 automotive qualification and are ROHS3 compliant, meeting automotive industry reliability and environmental standards.

Q: What is the significance of MSL 1 rating? A: MSL 1 (Unlimited) indicates these parts have unlimited shelf life and require no special moisture control during storage or handling, simplifying inventory management.

Q: Can I substitute based on manufacturer preference alone? A: No. Substitution must be based on matching all electrical specifications, package dimensions, and automotive qualifications. Manufacturer selection should follow product status and supply availability after confirming parameter equivalence.
