Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC1005F621CS are classified based on strict electrical and mechanical parameter alignment. The primary substitution criteria are:

Core Compatibility Parameters:

• Resistance value: 620 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Package: 0402 (1005 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature: -55°C to 155°C (exact match required)
• Terminations: 2 (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• MSL Rating: 1 (Unlimited) (exact match required)

Substitution Categories:

Direct Equivalents maintain all electrical and mechanical specifications identical to the main part, differing only in manufacturer and packaging format.

Upgrade Substitutes provide enhanced power rating (0.1W vs. 0.063W) while maintaining all other core parameters, suitable for applications requiring additional thermal margin.

Similar Substitutes add automotive AEC-Q200 qualification while preserving all electrical specifications, applicable for automotive-grade applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent Selection (CR0402-FX-6200GLF)

The Bourns CR0402-FX-6200GLF provides electrical and mechanical equivalence to the RC1005F621CS with identical 620 Ohm resistance, ±1% tolerance, 0.063W power rating, and 0402 package. Both components maintain ROHS3 compliance and MSL 1 rating. Selection is appropriate for standard industrial applications where moisture resistance is not explicitly required and Bourns sourcing is preferred.

Direct Equivalent with Moisture Resistance (RC0402FR-07620RL)

The YAGEO RC0402FR-07620RL maintains complete electrical and mechanical compatibility while preserving moisture-resistant construction matching the original specification. This part is suitable for direct substitution in applications requiring moisture protection with alternative packaging format (Cut Tape & Digi-Reel).

Upgrade Selection for Enhanced Thermal Performance (ERJ-2RKF6200X)

The Panasonic ERJ-2RKF6200X provides identical electrical specifications with increased power rating of 0.1W (versus 0.063W), enabling operation at higher power dissipation levels. Automotive AEC-Q200 qualification is included. This upgrade is applicable when thermal margin enhancement is required while maintaining all other parameters.

Automotive-Grade Selections (AC0402FR-07620RL, CRCW0402620RFKED, RMCF0402FT620R)

These three parts add Automotive AEC-Q200 qualification to the base 620 Ohm, ±1%, 0.063W specification. AC0402FR-07620RL (YAGEO) includes moisture resistance. CRCW0402620RFKED (Vishay Dale) and RMCF0402FT620R (Stackpole Electronics) provide automotive-grade alternatives without explicit moisture resistance designation. Selection depends on automotive application requirements and preferred supplier qualification.

Frequently Asked Questions (FAQ)

Q: Can CR0402-FX-6200GLF replace RC1005F621CS in all applications?

A: CR0402-FX-6200GLF provides complete electrical and mechanical equivalence with identical 620 Ohm resistance, ±1% tolerance, 0.063W power rating, and 0402 package. The primary difference is absence of explicit moisture-resistant designation. Substitution is valid for applications where moisture resistance is not a design requirement.

Q: What is the difference between the main part and ERJ-2RKF6200X?

A: ERJ-2RKF6200X maintains all electrical specifications (620 Ohms, ±1%, ±100ppm/°C, -55°C to 155°C) but provides enhanced power rating of 0.1W compared to 0.063W in the main part. Automotive AEC-Q200 qualification is included. This upgrade is suitable when higher power dissipation capability is required.

Q: Are automotive-grade parts (AC0402FR-07620RL, CRCW0402620RFKED, RMCF0402FT620R) backward compatible with non-automotive applications?

A: Yes. Automotive-grade parts maintain all electrical and mechanical specifications of the base 620 Ohm, ±1%, 0.063W, 0402 package design. AEC-Q200 qualification represents additional testing and quality assurance. These parts function identically in non-automotive applications.

Q: What packaging formats are available among substitute parts?

A: Tape & Reel (TR) packaging is available for CR0402-FX-6200GLF, ERJ-2RKF6200X, AC0402FR-07620RL, and RMCF0402FT620R. Cut Tape (CT) & Digi-Reel packaging is available for RC0402FR-07620RL and CRCW0402620RFKED. The main part RC1005F621CS uses Tape & Reel format.

Q: Do all substitute parts maintain ROHS3 compliance and MSL 1 rating?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity level, matching the main part specification.

Q: Which substitute part provides moisture resistance equivalent to RC1005F621CS?

A: RC0402FR-07620RL (YAGEO) and AC0402FR-07620RL (YAGEO) both include explicit moisture-resistant designation. RC0402FR-07620RL provides direct equivalence without automotive qualification. AC0402FR-07620RL adds AEC-Q200 automotive qualification while maintaining moisture resistance.

Q: Can I use RMCF0402FT620R as a direct replacement for RC1005F621CS?

A: RMCF0402FT620R maintains all electrical specifications (620 Ohms, ±1%, 0.063W, ±100ppm/°C, -55°C to 155°C) and 0402 package with ROHS3 compliance and MSL 1 rating. The addition of Automotive AEC-Q200 qualification does not prevent use in standard applications. Substitution is valid.
