Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F4870U is determined by strict equivalence across the following critical parameters:

• Resistance value: 487 Ohms
• Tolerance: ±1%
• Power rating: 0.5W
• Package type: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

The ERJ-14NF4870U qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications. Both parts share identical resistance, tolerance, power rating, package dimensions, temperature characteristics, and automotive certifications.

Engineering Selection Recommendations

The ERJ-S14F4870U is the preferred selection for new designs due to its active product status. The ERJ-14NF4870U is electrically and mechanically equivalent and remains suitable for existing designs, maintenance, and repair applications where the part is already qualified in the circuit.

For new product development, the ERJ-S14F4870U should be specified as the primary component. The ERJ-14NF4870U carries a "Not For New Designs" status, indicating Panasonic's recommendation to transition to the ERJ-S14 series for future applications. Both parts maintain full AEC-Q200 automotive qualification and ROHS3 compliance, ensuring regulatory and quality standards are met in either case.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF4870U be used as a direct replacement for ERJ-S14F4870U in automotive applications?

A: Yes. Both parts are AEC-Q200 qualified with identical electrical specifications (487 Ohms ±1%, 0.5W), temperature characteristics (±100ppm/°C, -55°C to 155°C), and package dimensions (1210). The substitution is electrically and mechanically valid for existing designs.

Q: What is the difference between ERJ-S14F4870U and ERJ-14NF4870U?

A: The primary difference is product lifecycle status. ERJ-S14F4870U is in active production, while ERJ-14NF4870U is designated "Not For New Designs." Both parts are functionally identical in electrical performance, package, and automotive certification. The ERJ-S14 series represents the current generation.

Q: Are both parts suitable for high-temperature automotive environments?

A: Yes. Both parts operate across -55°C to 155°C and carry AEC-Q200 automotive qualification. They are designed for automotive-grade reliability in temperature-variable environments.

Q: Do these parts require special handling or storage?

A: Both parts have MSL 1 (Unlimited) moisture sensitivity rating, indicating no special moisture control requirements during storage or handling. Standard component storage practices apply.

Q: Can these parts be used interchangeably on the same PCB assembly?

A: Yes. The parts are mechanically and electrically interchangeable. Both use 1210 package with identical footprint dimensions (3.20mm x 2.50mm length, 2.50mm width, 0.70mm maximum seated height), allowing direct PCB substitution without layout modifications.
