Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F821CS is determined by the following core parameters:

Critical Parameters (Must Match):

• Resistance value: 820 Ohms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Number of Terminations: 2
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Flexible Parameters (May Vary):

• Power Rating: 0.063W (1/16W) or higher
• Features: Moisture Resistant designation, Automotive AEC-Q200 qualification
• Packaging format: Tape & Reel (TR) or Cut Tape (CT) & Digi-Reel®

Substitute parts are grouped into three categories based on their relationship to the main part:

Direct Substitutes: Identical electrical and mechanical specifications with equivalent packaging.

Upgrade Substitutes: Enhanced power rating (0.1W vs. 0.063W) while maintaining all other critical parameters.

Similar Substitutes: Additional certifications (Automotive AEC-Q200) or enhanced features (moisture resistant) with identical core electrical specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitution (CR0402-FX-8200GLF): The Bourns CR0402-FX-8200GLF provides identical electrical and mechanical specifications to the RC1005F821CS. This part is suitable for applications where moisture resistance is not explicitly required and standard industrial operating conditions apply. ROHS3 compliance and MSL 1 rating ensure compatibility with standard PCB assembly processes.

Direct Substitution with Enhanced Availability (RC0402FR-07820RL): The YAGEO RC0402FR-07820RL matches all critical parameters and includes moisture resistant features identical to the main part. This option offers significantly higher inventory availability (500,400 pieces) and supports both Cut Tape and Digi-Reel® packaging formats, providing supply chain flexibility.

Upgrade Substitution (ERJ-2RKF8200X): The Panasonic ERJ-2RKF8200X provides enhanced power rating (0.1W vs. 0.063W) while maintaining all other electrical specifications. This part carries Automotive AEC-Q200 qualification and is suitable for applications requiring higher power dissipation capability or automotive-grade reliability. The upgrade path does not compromise any existing design parameters.

Automotive-Qualified Substitutes (AC0402FR-07820RL, CRCW0402820RFKED, RMCF0402FT820R): These three parts provide Automotive AEC-Q200 qualification with identical core electrical specifications. The YAGEO AC0402FR-07820RL additionally includes moisture resistant features. These options are appropriate for automotive applications, industrial environments requiring enhanced reliability, or designs where AEC-Q200 compliance is mandated. All three maintain ROHS3 compliance and MSL 1 rating.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-8200GLF replace RC1005F821CS in all applications?

A: CR0402-FX-8200GLF provides identical electrical and mechanical specifications. The primary difference is the absence of explicit moisture resistant designation. For applications in standard industrial environments without moisture exposure requirements, this part is fully compatible. For moisture-sensitive applications, RC0402FR-07820RL or AC0402FR-07820RL are recommended.

Q: What is the advantage of using ERJ-2RKF8200X?

A: ERJ-2RKF8200X provides 0.1W power rating compared to the 0.063W of the main part. This higher power rating allows the component to dissipate more heat without exceeding temperature limits. All other electrical parameters remain identical. This upgrade is beneficial for applications with higher current demands or thermal constraints.

Q: Are automotive-qualified parts (AC0402FR-07820RL, CRCW0402820RFKED, RMCF0402FT820R) suitable for non-automotive applications?

A: Yes. Automotive AEC-Q200 qualification represents enhanced reliability and stricter manufacturing controls. These parts are fully compatible with non-automotive applications and provide superior quality assurance. They are appropriate for any application where enhanced reliability is beneficial.

Q: Does packaging format affect electrical performance?

A: No. Tape & Reel (TR) and Cut Tape (CT) & Digi-Reel® packaging formats are assembly process considerations only. Electrical and mechanical specifications remain identical. Selection should be based on assembly equipment compatibility and supply chain requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, ensuring compatibility with standard PCB assembly processes and environmental regulations.

Q: Can I mix different manufacturers' parts in the same design?

A: Yes. All substitute parts meet identical electrical specifications (820Ω ±1%, ±100ppm/°C, -55°C ~ 155°C operating range). They are mechanically and electrically interchangeable within the 0402 package footprint. Mixing manufacturers is acceptable from an engineering standpoint.
