RC3225F3160CS Equivalent & Substitute Parts Reference

Part Overview

The RC3225F3160CS is a 316 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 with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility exist within the same package class, allowing direct replacement in circuit designs while maintaining functional performance and regulatory compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC3225F3160CS is determined by strict alignment with the following core parameters:

Mandatory Matching Criteria:

• Resistance value: 316 Ohms
• Tolerance: ±1%
• Package format: 1210 (3225 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Termination count: 2
• RoHS3 compliance

Allowable Variation:

• Power rating: Substitute parts may exceed the 0.333W specification, as higher power ratings provide equivalent or superior thermal performance in the same package footprint
• Packaging format: Original tape & reel (TR) packaging differs from the main part but does not affect electrical or mechanical compatibility in circuit applications
• Supplier device package designation: Remains 1210 across all qualified substitutes

The identified substitute parts CRCW1210316RFKEA (Vishay Dale) and ERJ-14NF3160U (Panasonic Electronic Components) meet all mandatory criteria while offering enhanced power dissipation ratings of 0.5W (1/2W).

Parameter Comparison

Engineering Selection Recommendations

CRCW1210316RFKEA (Vishay Dale) is the primary substitute option. This part maintains Active product status with full RoHS3 compliance and AEC-Q200 automotive qualification. The increased power rating of 0.5W provides thermal margin over the original 0.333W specification while maintaining identical electrical characteristics and mechanical compatibility within the 1210 package footprint.

ERJ-14NF3160U (Panasonic Electronic Components) is a secondary substitute option. Although this part meets all electrical and mechanical compatibility requirements with AEC-Q200 automotive qualification, it carries a "Not For New Designs" product status designation. This part remains suitable for replacement applications in existing designs but should not be selected for new circuit development.

Both substitute parts are RoHS3 compliant with MSL 1 rating and operate across the identical -55°C to 155°C temperature range. Selection between CRCW1210316RFKEA and ERJ-14NF3160U should prioritize CRCW1210316RFKEA for new designs due to its Active product status.

Frequently Asked Questions (FAQ)

Q: Can CRCW1210316RFKEA directly replace RC3225F3160CS in existing circuits?

A: Yes. Both parts share identical resistance (316 Ohms), tolerance (±1%), package format (1210), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C to 155°C). The higher power rating of CRCW1210316RFKEA (0.5W versus 0.333W) provides equivalent or superior performance in the same footprint.

Q: What is the significance of the "Not For New Designs" status on ERJ-14NF3160U?

A: This designation indicates that Panasonic has discontinued active development and promotion of this part number. While ERJ-14NF3160U remains functionally equivalent and suitable for replacement in existing designs, CRCW1210316RFKEA should be selected for new circuit development to ensure long-term supply availability and manufacturer support.

Q: Are there dimensional differences between these substitute parts?

A: All three parts conform to the 1210 (3225 Metric) package standard. Minor variations exist in maximum seated height (RC3225F3160CS: 0.66mm, CRCW1210316RFKEA: 0.60mm, ERJ-14NF3160U: 0.70mm) and length/width dimensions, but these fall within standard 1210 package tolerances and do not affect PCB layout compatibility or circuit performance.

Q: Do all substitute parts maintain RoHS3 compliance?

A: Yes. RC3225F3160CS, CRCW1210316RFKEA, and ERJ-14NF3160U are all ROHS3 compliant with REACH Unaffected status, meeting current environmental and regulatory requirements for electronic component manufacturing and use.

Q: What is the practical benefit of the higher power rating in substitute parts?

A: The 0.5W rating in CRCW1210316RFKEA and ERJ-14NF3160U provides thermal headroom for applications operating near the original 0.333W specification limit. This reduces junction temperature stress and extends component operational life in power-dissipative circuit conditions.
