ERJ-S14F1823U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F1823U is a 182 kOhms ±1% thick film chip resistor manufactured by Panasonic Electronic Components in the 1210 (3225 Metric) package format. This component is rated for 0.5W power dissipation and features anti-sulfur coating with AEC-Q200 automotive qualification. The part is currently in active production status with 934 units available in stock.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit selection from qualified alternatives that maintain electrical and mechanical compatibility within the same package and performance specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the ERJ-S14F1823U is determined by strict equivalence across the following critical parameters:

• Resistance value: 182 kOhms
• Tolerance: ±1%
• Power rating: 0.5W minimum
• Package format: 1210 (3225 Metric)
• Composition: Thick film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C minimum
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant

The ERJ-14NF1823U meets all substitution criteria and is qualified as a direct equivalent. This part maintains identical electrical specifications and package dimensions while differing only in product lifecycle status.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-S14F1823U is the preferred selection for new designs due to its active product status and full lifecycle support from Panasonic Electronic Components. This part carries no design obsolescence risk and maintains standard lead times.

The ERJ-14NF1823U is electrically and mechanically equivalent and carries the same AEC-Q200 automotive qualification and ROHS3 compliance. However, its "Not For New Designs" status indicates that Panasonic has transitioned this part to end-of-life phase. Selection of ERJ-14NF1823U is appropriate only when the ERJ-S14F1823U is unavailable and existing inventory of the substitute part is confirmed sufficient for the production volume and lifecycle requirements of the application.

Both parts satisfy identical electrical performance requirements, thermal specifications, and automotive reliability standards. The choice between them is driven by supply availability and design lifecycle considerations rather than technical performance differences.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF1823U be used as a direct replacement for ERJ-S14F1823U in automotive applications?

A: Yes. Both parts are AEC-Q200 qualified, share identical electrical specifications (182 kOhms ±1%, 0.5W), operate across the same temperature range (-55°C ~ 155°C), and use the same 1210 package format. The primary difference is product lifecycle status.

Q: What is the significance of the "Not For New Designs" status on ERJ-14NF1823U?

A: This designation indicates that Panasonic has discontinued active development and marketing of this part number. While existing inventory remains available and fully functional, the part will eventually reach end-of-life. New designs should prioritize ERJ-S14F1823U to avoid future obsolescence issues.

Q: Are there any package or footprint differences between these parts?

A: No. Both parts use the 1210 (3225 Metric) package with identical dimensions: 0.126" L x 0.098" W (3.20mm x 2.50mm) and maximum seated height of 0.028" (0.70mm). PCB footprints are interchangeable.

Q: Do both parts meet the same compliance and certification requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, carry AEC-Q200 automotive qualification, and have Moisture Sensitivity Level 1 (unlimited shelf life). Compliance profiles are identical.

Q: What inventory considerations should guide the selection between these parts?

A: ERJ-S14F1823U has 934 units in stock with active production support. ERJ-14NF1823U has 6937 units available but no new production planned. For immediate needs with limited quantities, ERJ-14NF1823U offers higher availability. For long-term or high-volume production, ERJ-S14F1823U ensures supply continuity.
