Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F2803U is determined by the following mandatory parameters:

• Resistance value: 280 kΩ (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 0.5W minimum
• Package: 1210 (3225 Metric) (exact match required)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to +155°C minimum
• Automotive qualification: AEC-Q200 (required for automotive applications)
• Termination count: 2

The following Panasonic parts meet these substitution criteria:

ERJ-P14F2803U — Active production status, RoHS3 compliant, includes pulse withstanding feature, identical electrical and mechanical specifications.

ERJ-14NF2803U — Discontinued for new designs, RoHS non-compliant, otherwise electrically and mechanically equivalent. Use only for legacy system maintenance or non-regulated applications.

Parameter Comparison

Engineering Selection Recommendations

For new designs and active production: Select ERJ-P14F2803U. This part maintains active production status, RoHS3 compliance, and includes pulse withstanding capability. All electrical and mechanical parameters are identical to the ERJ-S14F2803U, ensuring direct functional equivalence.

For legacy system maintenance or replacement: ERJ-14NF2803U is electrically and mechanically compatible but is marked "Not For New Designs" and does not meet RoHS3 compliance. Use only when ERJ-S14F2803U and ERJ-P14F2803U are unavailable and the application does not require RoHS compliance.

Compliance considerations: Both ERJ-S14F2803U and ERJ-P14F2803U are RoHS3 compliant and suitable for regulated markets. ERJ-14NF2803U is RoHS non-compliant and unsuitable for applications subject to RoHS directives.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P14F2803U replace ERJ-S14F2803U in automotive applications?

A: Yes. Both parts are AEC-Q200 qualified, share identical resistance (280 kΩ), tolerance (±1%), power rating (0.5W), package (1210), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to +155°C). The ERJ-P14F2803U adds pulse withstanding capability, which does not restrict its use as a substitute.

Q: What is the difference between ERJ-S14F2803U and ERJ-P14F2803U?

A: The primary difference is the special feature: ERJ-S14F2803U includes anti-sulfur protection, while ERJ-P14F2803U includes pulse withstanding capability. Both are active production parts with RoHS3 compliance. All electrical and mechanical specifications are identical.

Q: Is ERJ-14NF2803U suitable for new automotive designs?

A: No. ERJ-14NF2803U is marked "Not For New Designs" and is RoHS non-compliant. It is suitable only for legacy system maintenance or replacement in non-regulated applications.

Q: Are all three parts pin-compatible?

A: Yes. All three parts use the 1210 (3225 Metric) package with 2 terminations and identical dimensions (3.20mm × 2.50mm × 0.70mm max height). They are mechanically and electrically interchangeable at the PCB level.

Q: What is the moisture sensitivity level for these resistors?

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

Q: Can these parts be used in non-automotive applications?

A: Yes. While AEC-Q200 qualified for automotive use, these thick film resistors are suitable for general industrial, consumer, and commercial applications within the specified operating temperature range.
