Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F4020CS are classified based on strict electrical and mechanical parameter matching. The primary substitution criteria are:

Critical Matching Parameters:

• Resistance value: 402 Ohms
• Tolerance: ±1%
• Package format: 0402 (1005 Metric)
• Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Composition: Thick Film
• Number of terminations: 2

Substitution Categories:

Direct Equivalents maintain all electrical and mechanical specifications identical to the main part, including power rating (0.063W), moisture resistance features, and compliance certifications.

Upgrade Substitutes provide enhanced specifications such as higher power ratings (0.1W instead of 0.063W) or automotive-grade certifications (AEC-Q200) while maintaining all other critical parameters. These parts are suitable for applications requiring higher reliability margins or automotive qualification.

Similar Substitutes match all critical electrical and mechanical parameters but may differ in packaging format (Tape & Reel versus Cut Tape), compliance status, or include additional features such as automotive qualification. These parts are functionally equivalent for circuit operation but may require verification of supply chain and compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement without Specification Changes:

The CR0402-FX-4020GLF (Bourns Inc.) and RC0402FR-07402RL (YAGEO) are direct electrical and mechanical equivalents. Both maintain the 0.063W power rating, ±1% tolerance, and 0402 package format. RC0402FR-07402RL includes moisture resistant construction matching the original specification. Both are ROHS3 compliant and suitable for immediate substitution in existing designs.

For Applications Requiring Enhanced Reliability:

The ERJ-2RKF4020X (Panasonic Electronic Components) provides an upgrade path with 0.1W power rating and automotive AEC-Q200 qualification. This part is suitable for designs requiring higher thermal margin or automotive-grade component certification while maintaining all other critical parameters.

For Automotive and High-Reliability Applications:

The AC0402FR-07402RL (YAGEO), CRCW0402402RFKED (Vishay Dale), and RMCF0402FT402R (Stackpole Electronics Inc) all carry AEC-Q200 automotive qualification with ROHS3 compliance. These parts are appropriate for automotive circuits, industrial applications, or designs requiring enhanced qualification documentation. AC0402FR-07402RL additionally includes moisture resistant construction.

Compliance Consideration:

CRCW0402402RFKTD (Vishay Dale) is RoHS non-compliant and REACH affected. This part is not suitable for applications requiring ROHS3 compliance or REACH compliance verification.

Frequently Asked Questions (FAQ)

Q: Can I substitute CR0402-FX-4020GLF for RC1005F4020CS in my circuit?

A: Yes. Both parts share identical electrical specifications (402 Ω, ±1%, 0.063W), operate across the same temperature range (-55°C to 155°C), and use the 0402 package format with matching physical dimensions. Both are ROHS3 compliant. The primary difference is packaging format (Tape & Reel for both), making this a direct substitution.

Q: What is the difference between the 0.063W and 0.1W power ratings?

A: Power rating indicates the maximum continuous power dissipation the resistor can handle. The ERJ-2RKF4020X rated at 0.1W (1/10W) can dissipate more heat than the 0.063W (1/16W) rated parts. In circuits where the RC1005F4020CS operates below its 0.063W limit, the 0.1W rated ERJ-2RKF4020X provides additional thermal margin without affecting electrical performance. The 402 Ω resistance value and tolerance remain identical.

Q: Are automotive AEC-Q200 qualified parts suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification indicates the part meets automotive industry reliability and testing standards. These parts are suitable for any application, including consumer and industrial circuits. The qualification provides additional assurance of component quality and consistency.

Q: What does ROHS3 compliance mean for component selection?

A: ROHS3 (Restriction of Hazardous Substances Directive 3) compliance indicates the component does not contain restricted substances including lead, cadmium, mercury, and certain flame retardants. ROHS3 compliant parts are required for most commercial, industrial, and automotive applications sold in regulated markets. CRCW0402402RFKTD is not ROHS3 compliant and should not be used in designs requiring this certification.

Q: Does moisture resistant construction affect electrical performance?

A: No. Moisture resistant construction (present in RC1005F4020CS and RC0402FR-07402RL) provides enhanced protection against humidity and moisture ingress during storage and operation. This feature does not alter the electrical characteristics (resistance, tolerance, temperature coefficient) but improves long-term reliability in humid environments.

Q: Can I use Cut Tape packaging instead of Tape & Reel?

A: Yes, provided your assembly process accommodates the packaging format. Cut Tape (CT) & Digi-Reel® packaging is suitable for manual assembly or pick-and-place systems designed for this format. Tape & Reel (TR) packaging is standard for automated high-volume assembly. The electrical and mechanical specifications remain identical regardless of packaging format.

Q: What is the significance of Moisture Sensitivity Level (MSL) 1?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. Components with MSL 1 do not require special moisture control during storage or handling, simplifying supply chain management and reducing preparation time before assembly.
