Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F4223U is determined by strict equivalence across the following critical parameters:

Resistance value: 422 kOhms
Tolerance: ±1%
Power rating: 0.5W (1/2W)
Package / Case: 1210 (3225 Metric)
Composition: Thick Film
Temperature coefficient: ±100ppm/°C
Operating temperature range: -55°C ~ 155°C
Automotive qualification: AEC-Q200
Physical dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm)
Termination count: 2
Packaging format: Tape & Reel (TR)

The identified substitute ERJ-14NF4223U meets all electrical and mechanical parameters. Differences exist only in product status, RoHS compliance, and anti-sulfur coating availability, which do not affect functional interchangeability in applications where these specific certifications are not mandated.

Engineering Selection Recommendations

The ERJ-S14F4223U is the preferred selection for new designs due to its active product status, ROHS3 compliance, and anti-sulfur coating feature. This part is suitable for automotive and industrial applications requiring AEC-Q200 qualification and extended operating temperature ranges.

The ERJ-14NF4223U serves as a functional equivalent for applications where RoHS3 compliance and anti-sulfur coating are not contractual or regulatory requirements. This substitute is designated "Not For New Designs" by the manufacturer, indicating it is available for legacy system support and existing inventory management only. The absence of anti-sulfur coating may impact performance in high-sulfur environments typical of certain automotive applications.

Selection between these parts should be based on:

Regulatory compliance requirements (RoHS3 vs. non-compliant)
Environmental exposure to sulfur compounds
Design phase (new designs vs. legacy support)
Inventory availability and lead time constraints
Specific application certifications beyond AEC-Q200

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF4223U be used as a direct replacement for ERJ-S14F4223U in new automotive designs?

A: No. The ERJ-14NF4223U is marked "Not For New Designs" and lacks ROHS3 compliance. New designs must use the ERJ-S14F4223U or equivalent parts with active product status and current compliance certifications.

Q: What is the functional difference between the anti-sulfur coating on ERJ-S14F4223U and the standard ERJ-14NF4223U?

A: The anti-sulfur coating on the ERJ-S14F4223U provides enhanced protection against sulfur-containing atmospheric contaminants. In applications without sulfur exposure, both parts perform identically across all electrical parameters.

Q: Are the physical dimensions identical between these two parts?

A: Yes. Both parts share identical package dimensions (1210 / 3225 Metric), size (0.126" L x 0.098" W / 3.20mm x 2.50mm), and maximum seated height (0.028" / 0.70mm). They are mechanically interchangeable on PCB layouts.

Q: What does "Not For New Designs" mean for the ERJ-14NF4223U?

A: This designation indicates the manufacturer is not recommending this part for new product development. It remains available for existing inventory management and legacy system support but should not be selected for designs entering production after the designation date.

Q: Do both parts meet AEC-Q200 automotive qualification?

A: Yes. Both the ERJ-S14F4223U and ERJ-14NF4223U carry AEC-Q200 qualification and are suitable for automotive applications. The difference lies in RoHS compliance status and anti-sulfur coating availability, not automotive reliability standards.

Q: What is the difference in RoHS compliance between these parts?

A: The ERJ-S14F4223U is ROHS3 compliant, meeting current European Union Restriction of Hazardous Substances regulations. The ERJ-14NF4223U is RoHS non-compliant and cannot be used in applications subject to RoHS3 requirements.
