RC3225F97R6CS Equivalent & Substitute Parts

Part Overview

The RC3225F97R6CS is a 97.6 Ohm ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in the 1210 (3225 Metric) package format. This component is rated for 0.333W (1/3W) power dissipation and is designed for moisture-resistant applications across an operating temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Substitute parts become necessary when the primary component experiences supply constraints, extended lead times, or when design requirements permit alternative manufacturers while maintaining electrical and mechanical compatibility. The RC3225F97R6CS has documented substitute availability through equivalent part numbers that share critical electrical specifications and package dimensions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F97R6CS is determined by strict alignment with the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 97.6 Ohms
• Tolerance: ±1%
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• RoHS3 Compliance
• MSL 1 (Unlimited) rating

Allowable Variation:

• Power rating may exceed 0.333W (1/3W) without compromising compatibility, as higher power-rated components operate within the same thermal and electrical envelope for this package class
• Packaging format (bulk vs. Tape & Reel) does not affect electrical or mechanical substitution compatibility

The ERJ-14NF97R6U from Panasonic Electronic Components qualifies as a substitute based on matching all mandatory parameters while providing an increased power rating of 0.5W (1/2W).

Parameter Comparison

Engineering Selection Recommendations

Primary Component (RC3225F97R6CS): The Samsung Electro-Mechanics RC3225F97R6CS maintains Active product status, indicating ongoing manufacturer support and availability. This component is the preferred selection for new designs and applications requiring long-term supply assurance. The part is ROHS3 compliant and carries MSL 1 (Unlimited) rating, suitable for standard manufacturing environments without moisture-sensitive device handling protocols.

Substitute Component (ERJ-14NF97R6U): The Panasonic ERJ-14NF97R6U qualifies as an electrical and mechanical substitute based on identical resistance, tolerance, package dimensions, and environmental specifications. However, this component carries a "Not For New Designs" product status designation. The substitute is appropriate for legacy system maintenance, field replacements, or applications where existing inventory must be utilized. The increased power rating of 0.5W (1/2W) versus the original 0.333W (1/3W) provides additional thermal margin without introducing compatibility issues in the 1210 package format.

The ERJ-14NF97R6U includes AEC-Q200 automotive qualification, which represents an enhanced reliability certification not present in the primary component specification. This certification may provide additional assurance for applications requiring automotive-grade component reliability.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-14NF97R6U replace the RC3225F97R6CS in existing designs?

A: Yes. The ERJ-14NF97R6U provides electrical and mechanical compatibility based on matching resistance value (97.6 Ohms), tolerance (±1%), package format (1210), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Dimensional variations (0.098" vs. 0.100" width and 0.028" vs. 0.026" height) remain within standard PCB layout tolerances for 1210 package placement.

Q: What is the significance of the power rating difference between these components?

A: The RC3225F97R6CS is rated for 0.333W (1/3W) while the ERJ-14NF97R6U is rated for 0.5W (1/2W). In substitution scenarios, the higher power rating of the Panasonic component does not create incompatibility. The component will operate safely at or below the original design power dissipation level. The increased power rating provides additional thermal headroom and may improve long-term reliability in applications approaching the original component's power limits.

Q: Are there packaging format differences between these parts?

A: The RC3225F97R6CS is supplied in standard packaging format, while the ERJ-14NF97R6U is supplied in Tape & Reel (TR) format. Packaging format does not affect electrical performance or mechanical compatibility. Format selection depends on manufacturing process requirements and volume handling procedures.

Q: Why does the ERJ-14NF97R6U carry "Not For New Designs" status?

A: The "Not For New Designs" designation indicates that Panasonic has classified this part number as legacy or transitional. New product development should prioritize the RC3225F97R6CS (Active status) for long-term supply continuity. The ERJ-14NF97R6U remains suitable for field replacements, maintenance applications, or situations where existing inventory must be consumed.

Q: Are both components ROHS3 compliant?

A: Yes. Both the RC3225F97R6CS and ERJ-14NF97R6U are ROHS3 compliant, confirming the absence of restricted substances (lead, cadmium, hexavalent chromium, polybrominated biphenyls, polybrominated diphenyl ethers, and bis(2-ethylhexyl) phthalate) within specified concentration limits.

Q: What does MSL 1 (Unlimited) moisture sensitivity rating mean?

A: MSL 1 (Unlimited) indicates that the component has no moisture sensitivity restrictions. Standard manufacturing processes do not require special moisture-sensitive device (MSD) handling protocols, floor life limitations, or bake-out procedures prior to soldering. Both components carry this rating.

Q: Can these components be used interchangeably in automated assembly?

A: Yes. Both components are supplied in standard 1210 package format with compatible dimensions and termination configurations. Automated pick-and-place equipment can handle both parts without modification. Tape & Reel packaging (ERJ-14NF97R6U) may require feeder compatibility verification with specific assembly equipment.
