Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1608F5R6CS are qualified based on the following critical parameters:

Electrical Equivalence: Resistance value of 5.6 Ohms with ±1% tolerance and 0.1W power rating must be maintained.

Mechanical Compatibility: Package designation 0603 (1608 Metric) with identical footprint dimensions (0.063" L x 0.031" W / 1.60mm x 0.80mm) and maximum seated height of 0.022" (0.55mm).

Environmental & Compliance: Operating temperature range -55°C ~ 155°C, ROHS3 compliance, MSL 1 rating, and REACH unaffected status.

Composition & Construction: Thick film resistor technology with two terminations.

All identified substitutes meet these core parameters. Additional features such as automotive AEC-Q200 qualification or enhanced temperature coefficient performance represent supplementary capabilities that do not prevent substitution but may offer improved performance characteristics for specific applications.

Parameter Comparison

Frequently Asked Questions (FAQ)

Q: Can ERJ-3RQF5R6V replace RC1608F5R6CS in existing designs?

A: Yes. Both components share identical resistance value (5.6 Ohms), tolerance (±1%), power rating (0.1W), package designation (0603), operating temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, MSL 1). The ERJ-3RQF5R6V features a lower temperature coefficient (±200ppm/°C versus ±300ppm/°C), which represents improved performance. No circuit redesign is required.

Q: What is the difference between RMCF0603FT5R60 and RC1608F5R6CS?

A: Electrical specifications are identical. Physical dimensions differ slightly: RMCF0603FT5R60 measures 0.061" L x 0.031" W (1.55mm x 0.80mm) compared to RC1608F5R6CS at 0.063" L x 0.031" W (1.60mm x 0.80mm). Both conform to 0603 package specification. RMCF0603FT5R60 includes AEC-Q200 automotive qualification. Maximum seated height remains 0.022" (0.55mm) for both parts.

Q: Are all substitute parts automotive qualified?

A: ERJ-3RQF5R6V, RMCF0603FT5R60, and KTR03EZPF5R60 all carry AEC-Q200 automotive qualification. The original RC1608F5R6CS does not list AEC-Q200 certification. Substitutes may be used in automotive applications where the original part was not qualified.

Q: Which substitute has the best temperature stability?

A: ERJ-3RQF5R6V, RMCF0603FT5R60, and KTR03EZPF5R60 all specify ±200ppm/°C temperature coefficient, compared to RC1608F5R6CS at ±300ppm/°C. All three substitutes provide superior temperature stability across the -55°C ~ 155°C operating range.

Q: Can these parts be used interchangeably in production?

A: Yes, for applications where electrical performance, package compatibility, and compliance requirements are met. All parts are Active product status with identical core specifications. Verify PCB footprint compatibility and confirm that any additional features (automotive qualification, current sense capability, high voltage rating) do not conflict with application requirements.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake requirements. All four parts (original and substitutes) carry MSL 1 rating, eliminating moisture-related handling constraints during storage and assembly.
