ERJ-S14F93R1U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F93R1U is a 93.1 Ohm ±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 meets AEC-Q200 automotive qualification standards with anti-sulfur protection. The part is currently in active production status. Substitute parts are necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements permit selection from qualified alternative manufacturers meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ERJ-S14F93R1U are qualified based on strict equivalence across the following parameters: resistance value (93.1 Ohms), tolerance (±1%), power rating (0.5W), package format (1210 / 3225 Metric), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive qualification (AEC-Q200). All substitute parts must maintain identical electrical performance characteristics and physical dimensions to ensure direct interchangeability in circuit applications. Compliance with RoHS3 and MSL 1 ratings is maintained across all qualified substitutes.

Engineering Selection Recommendations

For new design implementations, the ERJ-S14F93R1U (Panasonic, Active status) or RMCF1210FT93R1 (Stackpole, Active status) are the preferred selections due to their active product status and ongoing manufacturer support. The ERJ-14NF93R1U carries a "Not For New Designs" designation and should be reserved for legacy system maintenance or replacement applications only. All three parts satisfy identical electrical specifications, AEC-Q200 automotive qualification, and RoHS3 compliance requirements. Selection between active-status alternatives may be determined by supply availability, lead time, or established supplier relationships.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF93R1U be used as a direct replacement for ERJ-S14F93R1U? A: Electrical and mechanical compatibility is complete. However, ERJ-14NF93R1U is designated "Not For New Designs" by the manufacturer. Use this part only for legacy system repairs or maintenance where the original part number is unavailable.

Q: What is the difference between Panasonic ERJ-S14 and ERJ-14N series? A: Both series share identical electrical specifications (93.1 Ohms ±1%, 0.5W, AEC-Q200). The ERJ-S14 series includes anti-sulfur protection and maintains active production status. The ERJ-14N series is in legacy status. Physical package dimensions and performance characteristics are equivalent.

Q: Is RMCF1210FT93R1 from Stackpole fully compatible with Panasonic parts? A: Yes. RMCF1210FT93R1 meets all specified parameters: 93.1 Ohms ±1%, 0.5W power rating, 1210 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and AEC-Q200 automotive qualification. Direct substitution is permissible.

Q: Are there any package or footprint differences between these parts? A: No. All three 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 all substitute parts meet automotive qualification requirements? A: Yes. ERJ-S14F93R1U, ERJ-14NF93R1U, and RMCF1210FT93R1 all carry AEC-Q200 automotive qualification and are suitable for automotive applications within the specified operating temperature range.

Q: What is the significance of MSL 1 rating? A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life with no special moisture control requirements during storage or handling. All three parts share this rating.
