RC3225F84R5CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F84R5CS is a 84.5 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics, rated at 0.333W (1/3W) power dissipation in a 1210 (3225 Metric) package. This component is classified as Active product status with moisture-resistant construction and unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package form factor and core performance parameters. The primary substitute identified is the ERJ-14NF84R5U from Panasonic Electronic Components, which shares identical resistance, tolerance, and package dimensions while offering higher power rating and automotive qualification.

Substitute Part Grouping Explanation

Substitution logic for the RC3225F84R5CS is based on the following mandatory alignment criteria:

Electrical Parameters (Must Match):

• Resistance value: 84.5 Ohms
• Tolerance: ±1%
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters (Must Match):

• Package form factor: 1210 (3225 Metric)
• Composition: Thick Film
• Number of terminations: 2

Flexible Parameters (Can Exceed Specification):

• Power rating: Substitute may equal or exceed 0.333W minimum
• Moisture sensitivity level: Substitute must maintain MSL 1 or better
• RoHS compliance: Must maintain ROHS3 Compliant status

The ERJ-14NF84R5U qualifies as a direct substitute because it maintains all mandatory electrical and mechanical parameters while providing enhanced power rating (0.5W vs. 0.333W) and automotive-grade qualification (AEC-Q200). Higher power rating does not compromise circuit function and provides additional thermal margin.

Frequently Asked Questions (FAQ)

Q: Can ERJ-14NF84R5U replace RC3225F84R5CS in existing designs?

A: Yes. The ERJ-14NF84R5U maintains identical electrical specifications (84.5 Ohms ±1%, ±100ppm/°C, -55°C ~ 155°C) and package form factor (1210 / 3225 Metric). Physical dimensions are compatible within PCB layout tolerances. The higher power rating (0.5W vs. 0.333W) does not create functional incompatibility.

Q: What is the significance of the "Not For New Designs" status on ERJ-14NF84R5U?

A: This designation indicates Panasonic has classified this part for legacy support only. New product designs should prioritize RC3225F84R5CS or equivalent active-status alternatives. The substitute remains electrically and mechanically valid for replacement applications.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. RC3225F84R5CS measures 0.126" L x 0.100" W (3.20mm x 2.55mm) with 0.026" max height. ERJ-14NF84R5U measures 0.126" L x 0.098" W (3.20mm x 2.50mm) with 0.028" max height. These differences are within standard PCB layout tolerances and do not affect interchangeability.

Q: Does ERJ-14NF84R5U require different handling procedures?

A: Both parts maintain MSL 1 (Unlimited) moisture sensitivity level, requiring identical storage and handling protocols. ERJ-14NF84R5U's Tape & Reel packaging differs from RC3225F84R5CS standard packaging, affecting supply chain logistics but not component performance.

Q: What compliance certifications apply to both parts?

A: Both RC3225F84R5CS and ERJ-14NF84R5U are ROHS3 Compliant and REACH Unaffected. ERJ-14NF84R5U carries additional AEC-Q200 automotive qualification. Both are classified under ECCN EAR99 and HTSUS 8533.21.0030.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts operate across the identical temperature range (-55°C ~ 155°C) with matching temperature coefficient (±100ppm/°C). Thermal performance is equivalent within their respective power ratings.
