Key Parameters

Substitute Part Grouping Explanation

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

Primary Equivalence Criteria:

• Resistance value: 80.6 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Package / Case: 0402 (1005 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)

Secondary Compatibility Factors:

• Power rating: 0.063W minimum (higher ratings acceptable as upgrades)
• Packaging format: Cut Tape (CT), Tape & Reel (TR), or Digi-Reel® (format variation acceptable)
• Moisture Sensitivity Level: MSL 1 (unlimited) required
• RoHS compliance: ROHS3 Compliant preferred; non-compliant parts noted separately
• Automotive certification: AEC-Q200 available as optional enhancement

All substitute parts listed meet primary equivalence criteria. Variations in secondary factors are explicitly documented in the comparison table.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (No Functional Difference):

• CR0402-FX-80R6GLF (Bourns Inc.): Identical electrical and thermal specifications. Packaging format differs (Tape & Reel vs. Cut Tape). Suitable for high-volume automated assembly processes.
• RC0402FR-0780R6L (YAGEO): Functionally equivalent with moisture-resistant construction matching the original part. Available in multiple packaging formats. ROHS3 compliant.

Direct Equivalent with Enhanced Power Rating:

• ERJ-2RKF80R6X (Panasonic Electronic Components): Provides 0.1W power rating (upgrade from 0.063W) while maintaining all other specifications. Automotive AEC-Q200 certified. Suitable for applications requiring higher thermal margin or automotive-grade reliability.

Equivalent with Automotive Certification:

• AC0402FR-0780R6L (YAGEO): Adds Automotive AEC-Q200 certification and moisture-resistant features. Identical power and electrical specifications. Tape & Reel packaging.
• CRCW040280R6FKED (Vishay Dale): Automotive AEC-Q200 certified. ROHS3 compliant. Tape & Reel packaging.
• RMCF0402FT80R6 (Stackpole Electronics Inc): Automotive AEC-Q200 certified. ROHS3 compliant. Highest inventory availability (805,446 pcs). Tape & Reel packaging.

Equivalent with Compliance Limitation:

• CRCW040280R6FKTD (Vishay Dale): Functionally equivalent but marked as RoHS non-compliant and REACH Affected. Use only in applications where RoHS3 compliance is not required.

Selection Basis:

• For standard industrial applications: CR0402-FX-80R6GLF or RC0402FR-0780R6L
• For automotive applications: ERJ-2RKF80R6X, AC0402FR-0780R6L, CRCW040280R6FKED, or RMCF0402FT80R6
• For high-volume supply: RMCF0402FT80R6 (largest inventory)
• For RoHS3 compliance requirement: Avoid CRCW040280R6FKTD

Frequently Asked Questions (FAQ)

Q: Can I substitute RC1005F80R6CS with any of the listed parts without circuit redesign?

A: Yes. All listed substitute parts meet the primary equivalence criteria: 80.6 Ohms resistance, ±1% tolerance, 0402 package, thick film composition, ±100ppm/°C temperature coefficient, and -55°C to 155°C operating range. Direct substitution is electrically valid. Packaging format changes (Cut Tape to Tape & Reel) affect assembly process only, not circuit function.

Q: What is the difference between the main part and ERJ-2RKF80R6X?

A: The ERJ-2RKF80R6X provides a higher power rating (0.1W vs. 0.063W) and includes Automotive AEC-Q200 certification. All other electrical parameters are identical. The higher power rating allows greater thermal dissipation, making it suitable for applications with higher current or ambient temperature stress. This is an upgrade path, not a downgrade.

Q: Why is CRCW040280R6FKTD marked as RoHS non-compliant?

A: CRCW040280R6FKTD is flagged as RoHS non-compliant and REACH Affected based on the provided data. This part should be used only in applications or regions where RoHS3 compliance is not mandated. All other substitute parts listed are ROHS3 compliant.

Q: Does packaging format (Cut Tape vs. Tape & Reel) affect electrical performance?

A: No. Packaging format affects only the physical delivery and handling method for assembly automation. Cut Tape (CT) is suitable for manual or semi-automated placement. Tape & Reel (TR) and Digi-Reel® formats are optimized for high-speed automated pick-and-place equipment. Electrical specifications remain identical regardless of packaging format.

Q: Are all substitute parts available in the same moisture sensitivity level?

A: Yes. All substitute parts listed have MSL 1 (Unlimited), matching the original RC1005F80R6CS. This means no special moisture control or baking procedures are required during storage or handling.

Q: Which substitute part has the largest inventory availability?

A: RMCF0402FT80R6 (Stackpole Electronics Inc) has the highest inventory at 805,446 pieces. This part is ROHS3 compliant, Automotive AEC-Q200 certified, and available in Tape & Reel format.

Q: Can I use an automotive-grade part (AEC-Q200) in a non-automotive application?

A: Yes. Automotive-grade parts meet or exceed standard industrial specifications. Using an AEC-Q200 certified part in a non-automotive application provides additional reliability margin without any compatibility issues. This is a conservative design choice.

Q: What is the temperature coefficient specification, and why does it matter?

A: The temperature coefficient of ±100ppm/°C indicates that the resistance value changes by a maximum of 100 parts per million for each degree Celsius change in operating temperature. All listed parts share this specification, ensuring consistent performance across the -55°C to 155°C operating range. This parameter is critical for precision analog circuits and temperature-sensitive applications.
