ERJ-S14F36R5U Equivalent & Substitute Parts

Part Overview

The ERJ-S14F36R5U is a 36.5 Ohm ±1% thick film chip resistor manufactured by Panasonic Electronic Components in the 1210 (3225 Metric) package. 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 may be required due to supply constraints, manufacturing discontinuation of specific series variants, or design flexibility across qualified automotive component families.

Engineering Selection Recommendations

ERJ-S14F36R5U (Primary Selection): This part is in active production status and includes anti-sulfur protection. It is the preferred choice for new designs and applications requiring long-term supply continuity.

CRCW121036R5FKEA (Cross-Manufacturer Substitute): This Vishay Dale equivalent is in active production status and meets all electrical and mechanical requirements. The seated height is 0.024" (0.60mm) compared to 0.028" (0.70mm) for the Panasonic variant. This minor dimensional difference is within typical PCB design tolerances for 1210 package components and does not affect electrical performance or mechanical fit in standard applications.

ERJ-14NF36R5U (Legacy Panasonic Variant): This part is marked as "Not For New Designs" and should be used only for replacement or maintenance of existing assemblies where supply of the primary ERJ-S14F36R5U is unavailable. It is electrically and mechanically identical to the primary part.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF36R5U be used as a direct replacement for ERJ-S14F36R5U? A: Yes. Both parts are electrically and mechanically identical with matching resistance, tolerance, power rating, package dimensions, and AEC-Q200 certification. However, ERJ-14NF36R5U is designated "Not For New Designs," so ERJ-S14F36R5U should be the primary selection for new applications.

Q: Is CRCW121036R5FKEA compatible with ERJ-S14F36R5U in automotive applications? A: Yes. The CRCW121036R5FKEA meets all electrical specifications and AEC-Q200 automotive qualification requirements. The seated height difference of 0.004" (0.10mm) is negligible for standard PCB assembly and does not affect circuit performance or mechanical reliability.

Q: What is the significance of the anti-sulfur feature on ERJ-S14F36R5U? A: Anti-sulfur protection is a material enhancement that prevents sulfur-induced corrosion on component terminations in high-sulfur environments. This feature is present on ERJ-S14F36R5U but not explicitly listed for ERJ-14NF36R5U or CRCW121036R5FKEA. For applications in sulfur-prone environments, ERJ-S14F36R5U is the recommended choice.

Q: Are all three parts suitable for the full -55°C ~ 155°C temperature range? A: Yes. All three parts are rated for the identical operating temperature range of -55°C to 155°C with a temperature coefficient of ±100ppm/°C.

Q: What is the difference between the ERJ-S14 and ERJ-14N series? A: Both are Panasonic thick film chip resistor series in the 1210 package. The ERJ-S14 series is in active production, while the ERJ-14N series is designated "Not For New Designs." Electrical and mechanical specifications are equivalent.

Q: Can these parts be used interchangeably in PCB assembly? A: Yes, for standard PCB assembly processes. All three parts use identical 1210 package footprints and have compatible termination configurations. The minor height variation of the CRCW121036R5FKEA does not affect standard reflow soldering or mechanical assembly.
