RC1005F2100CS Equivalent & Substitute Parts Reference

Part Overview

The RC1005F2100CS is a 210 Ohms ±1% thick film chip resistor manufactured by Samsung Electro-Mechanics in 0402 (1005 Metric) package format. This component is rated at 0.063W (1/16W) power dissipation with moisture-resistant construction and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are identified when design requirements necessitate alternative sourcing due to inventory constraints, supply chain considerations, or specific application certifications such as automotive AEC-Q200 qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC1005F2100CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 210 Ohms
• Tolerance: ±1%
• Package / Case: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant
• Number of Terminations: 2

Allowable Variation:

• Power Rating: Substitute parts may equal or exceed the 0.063W (1/16W) specification
• Automotive Certification: AEC-Q200 qualification is an enhancement and does not disqualify substitution

Substitute parts are categorized as follows:

Direct Equivalent: RC0402FR-07210RL (YAGEO) matches all parameters identically to the main part.

Upgrade Category: ERJ-2RKF2100X (Panasonic) provides increased power rating (0.1W vs. 0.063W) with automotive AEC-Q200 certification.

Similar Category: AC0402FR-07210RL (YAGEO), CRCW0402210RFKED (Vishay Dale), and RMCF0402FT210R (Stackpole Electronics Inc) maintain identical electrical specifications with automotive AEC-Q200 certification added.

Parameter Comparison

Engineering Selection Recommendations

For Non-Automotive Applications: RC0402FR-07210RL (YAGEO) serves as the direct equivalent substitute with identical electrical and mechanical specifications. This part maintains full compatibility with the original RC1005F2100CS design without modification.

For Automotive Applications or Enhanced Reliability: AC0402FR-07210RL (YAGEO), CRCW0402210RFKED (Vishay Dale), or RMCF0402FT210R (Stackpole Electronics Inc) are suitable selections. These parts carry AEC-Q200 automotive qualification while maintaining identical electrical performance to the main part.

For Applications Requiring Increased Power Margin: ERJ-2RKF2100X (Panasonic Electronic Components) provides 0.1W power rating versus the 0.063W specification of the main part, with AEC-Q200 certification. This upgrade is applicable when thermal stress reduction or design margin enhancement is required.

All substitute parts maintain ROHS3 compliance, unlimited moisture sensitivity level (MSL 1), and identical operating temperature range (-55°C to 155°C). Physical dimensions and termination count remain consistent across all listed alternatives.

Frequently Asked Questions (FAQ)

Q: Can RC0402FR-07210RL replace RC1005F2100CS in any application?

A: Yes. RC0402FR-07210RL matches all critical electrical and mechanical parameters of RC1005F2100CS. Both parts are 210 Ohms ±1%, 0.063W, 0402 package, thick film composition, with ±100ppm/°C temperature coefficient and -55°C to 155°C operating range. Direct substitution is valid without circuit modification.

Q: What is the difference between the main part and AEC-Q200 qualified substitutes?

A: The main part RC1005F2100CS does not carry AEC-Q200 automotive qualification. Substitute parts AC0402FR-07210RL, CRCW0402210RFKED, and RMCF0402FT210R include AEC-Q200 certification, indicating compliance with automotive reliability and quality standards. Electrical specifications remain identical.

Q: Can ERJ-2RKF2100X be used as a direct replacement?

A: ERJ-2RKF2100X is electrically compatible but features increased power rating (0.1W versus 0.063W). This upgrade does not create incompatibility; the higher power rating provides additional thermal margin. Physical dimensions and all other parameters match the main part. Substitution is valid for applications where the original power specification is met or exceeded.

Q: Are there packaging differences between these parts?

A: RC1005F2100CS, RC0402FR-07210RL, ERJ-2RKF2100X, AC0402FR-07210RL, and RMCF0402FT210R are supplied in Tape & Reel (TR) packaging. CRCW0402210RFKED is available in Cut Tape (CT) & Digi-Reel® packaging. All parts use identical 0402 (1005 Metric) component package format suitable for automated assembly.

Q: Do all substitute parts meet RoHS requirements?

A: Yes. All listed substitute parts maintain ROHS3 compliance identical to the main part RC1005F2100CS. REACH status is unaffected for all alternatives.

Q: What is the significance of MSL 1 (Unlimited) rating?

A: MSL 1 indicates unlimited shelf life without moisture baking requirements. All listed parts, including the main part and all substitutes, carry MSL 1 rating, eliminating moisture sensitivity concerns during storage and handling.
