Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1608F46R4CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications: Resistance value (46.4 Ohms), tolerance (±1%), and power rating (0.1W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries.

Mechanical Compatibility: Package designation (0603 / 1608 Metric), physical dimensions (0.063" L x 0.031" W / 1.60mm x 0.80mm), and height (0.022" / 0.55mm maximum seated) ensure PCB footprint compatibility and assembly process alignment.

Regulatory & Environmental Compliance: RoHS3 compliance and MSL Level 1 rating are mandatory for substitution. REACH unaffected status and EAR99 ECCN classification apply uniformly across all qualified substitutes.

Packaging Format: Tape & Reel (TR) packaging maintains supply chain consistency and automated assembly compatibility.

All identified substitute parts meet these criteria without exception.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Preferred): RC0603FR-0746R4L (YAGEO) provides identical electrical and mechanical specifications with 96,206 units in stock. This part maintains feature parity with the primary component and is suitable for direct substitution without design modification.

Automotive-Qualified Alternatives: CRCW060346R4FKEA (Vishay Dale), ERJ-3EKF46R4V (Panasonic), and RMCF0603FT46R4 (Stackpole) incorporate AEC-Q200 automotive qualification. These parts are electrically and mechanically equivalent with the exception of CRCW060346R4FKEA, which has a maximum seated height of 0.020" (0.50mm) versus 0.022" (0.55mm) for other variants. All automotive-qualified options maintain RoHS3 compliance and MSL Level 1 rating.

Inventory Availability: Selection should consider stock levels: YAGEO RC0603FR-0746R4L (96,206 units), Panasonic ERJ-3EKF46R4V (50,426 units), Vishay Dale CRCW060346R4FKEA (23,755 units), and Stackpole RMCF0603FT46R4 (5,639 units).

Compliance Verification: All substitute parts maintain identical RoHS3 compliance, REACH unaffected status, and EAR99 ECCN classification. No additional regulatory documentation is required for substitution.

Frequently Asked Questions (FAQ)

Q: Can RC0603FR-0746R4L replace RC1608F46R4CS directly?

A: Yes. RC0603FR-0746R4L is a direct equivalent with identical resistance (46.4 Ohms), tolerance (±1%), power rating (0.1W), package (0603), temperature coefficient (±100ppm/°C), operating range (-55°C ~ 155°C), and compliance certifications. No circuit redesign is required.

Q: What is the difference between the Samsung part and automotive-qualified substitutes?

A: The primary difference is AEC-Q200 automotive qualification present in CRCW060346R4FKEA, ERJ-3EKF46R4V, and RMCF0603FT46R4. All other electrical and mechanical parameters remain identical. The Samsung RC1608F46R4CS does not carry AEC-Q200 rating but is suitable for general industrial applications.

Q: Does the height difference in CRCW060346R4FKEA affect compatibility?

A: CRCW060346R4FKEA has a maximum seated height of 0.020" (0.50mm) compared to 0.022" (0.55mm) for other variants. This 0.002" (0.05mm) difference is within typical PCB assembly tolerances and does not affect electrical performance or mechanical fit on standard 0603 footprints.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All identified substitute parts—RC0603FR-0746R4L, CRCW060346R4FKEA, ERJ-3EKF46R4V, and RMCF0603FT46R4—are RoHS3 compliant with MSL Level 1 rating and REACH unaffected status.

Q: Which substitute offers the best inventory availability?

A: YAGEO RC0603FR-0746R4L has the highest stock level at 96,206 units, followed by Panasonic ERJ-3EKF46R4V at 50,426 units. Both are suitable for high-volume production requirements.

Q: Can these parts be used interchangeably in the same PCB assembly?

A: Yes. All substitute parts share identical 0603 (1608 Metric) package designation, footprint dimensions (0.063" L x 0.031" W / 1.60mm x 0.80mm), and Tape & Reel packaging format. They are compatible with standard automated assembly equipment and PCB layouts designed for 0603 resistors.
