Substitute Part Grouping Explanation

Substitution of the ERJ-S14J433U is based on strict equivalence of the following electrical and mechanical parameters:

• Resistance value: 43 kOhms
• Tolerance: ±5%
• Power rating: 0.5W (1/2W)
• Package type: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°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)
• Height - Seated (Max): 0.028" (0.70mm)
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1 (Unlimited)

The ERJ-14YJ433U meets all these criteria and is identified as a direct substitute. This part is manufactured by the same supplier (Panasonic Electronic Components) and maintains identical electrical specifications and physical form factor.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14J433U is the preferred selection for new designs due to its active production status. The ERJ-14YJ433U is electrically and mechanically equivalent but carries a "Not For New Designs" status, indicating it is in mature or end-of-life phase. Both parts meet AEC-Q200 automotive qualification requirements and ROHS3 compliance standards. Selection between these parts should be based on design phase requirements and supply chain availability. For ongoing production and new design implementations, the ERJ-S14J433U is the recommended primary choice.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14YJ433U be used as a direct replacement for ERJ-S14J433U?

A: Yes. Both parts are electrically and mechanically equivalent with identical resistance (43 kOhms ±5%), power rating (0.5W), package (1210), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The primary difference is product status; ERJ-14YJ433U is not recommended for new designs.

Q: Are the physical dimensions identical between these parts?

A: Yes. Both parts have identical dimensions of 0.126" L x 0.098" W (3.20mm x 2.50mm) with maximum seated height of 0.028" (0.70mm), ensuring identical PCB footprint compatibility.

Q: Do both parts meet automotive standards?

A: Yes. Both ERJ-S14J433U and ERJ-14YJ433U carry AEC-Q200 qualification, suitable for automotive applications within the specified operating temperature range of -55°C ~ 155°C.

Q: What is the significance of the product status difference?

A: ERJ-S14J433U (Active) is in current production and recommended for new designs. ERJ-14YJ433U (Not For New Designs) indicates the part is available but not recommended for new product development, typically due to planned discontinuation or transition to newer series.

Q: Are moisture sensitivity levels the same?

A: Yes. Both parts have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions and no special storage or handling requirements.
