Parameter Comparison

Engineering Selection Recommendations

RC0402FR-073R3L (YAGEO): This substitute is electrically and mechanically identical to the RC1005F3R3CS with improved temperature coefficient performance (±200ppm/°C versus ±300ppm/°C). Both parts maintain ROHS3 compliance and MSL 1 rating. The primary distinction is packaging format (Cut Tape & Digi-Reel® versus Tape & Reel) and significantly higher inventory availability (10300 units). Selection of this part is appropriate for applications where packaging flexibility is acceptable and supply continuity is prioritized.

RMCF0402FT3R30 (Stackpole Electronics Inc): This substitute provides identical electrical and mechanical specifications with the addition of Automotive AEC-Q200 qualification. Temperature coefficient is improved to ±200ppm/°C. The part maintains full ROHS3 and MSL 1 compliance. Highest inventory availability (34229 units) supports supply chain resilience. Selection of this part is appropriate for automotive applications, applications requiring AEC-Q200 certification, or where enhanced reliability qualification is specified.

All three parts satisfy the core substitution criteria: identical resistance, tolerance, power rating, package format, operating temperature range, moisture resistance, and regulatory compliance status.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-073R3L replace RC1005F3R3CS in any application?

A: Yes. Both parts share identical electrical specifications (3.3 Ohms ±1%, 0.063W), mechanical dimensions (0402 package), operating temperature range (-55°C ~ 155°C), and regulatory compliance (ROHS3, MSL 1). The RC0402FR-073R3L features improved temperature coefficient (±200ppm/°C). Packaging format differs (Cut Tape & Digi-Reel® versus Tape & Reel), which affects handling and assembly processes but not electrical performance.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel® packaging?

A: Tape & Reel (TR) provides components on continuous carrier tape wound on a reel, suitable for automated pick-and-place assembly. Cut Tape (CT) & Digi-Reel® provides components on cut tape segments with optional reel packaging, offering flexibility for mixed manual and automated assembly. Both formats contain identical components; packaging selection depends on assembly equipment and process requirements.

Q: Is RMCF0402FT3R30 suitable for non-automotive applications?

A: Yes. RMCF0402FT3R30 meets all electrical and mechanical requirements for the RC1005F3R3CS application. The Automotive AEC-Q200 qualification represents an additional certification that does not restrict use in non-automotive applications. This part is suitable for any application requiring 3.3 Ohm ±1% 0402 thick film resistors with -55°C ~ 155°C operating range.

Q: What does Temperature Coefficient ±200ppm/°C versus ±300ppm/°C mean for substitution?

A: Temperature coefficient defines resistance change per degree Celsius. Lower absolute values indicate greater stability across temperature variations. RC0402FR-073R3L and RMCF0402FT3R30 both feature ±200ppm/°C, providing superior temperature stability compared to RC1005F3R3CS at ±300ppm/°C. This represents an improvement and does not restrict substitution in applications designed for the original part.

Q: Are all three parts ROHS3 compliant?

A: Yes. RC1005F3R3CS, RC0402FR-073R3L, and RMCF0402FT3R30 are all ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic components.

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

A: MSL (Moisture Sensitivity Level) 1 indicates the component has unlimited shelf life without moisture bake-out requirements. All three parts carry this rating, eliminating moisture-related handling constraints during storage and assembly.
