RC6432F1821CS Equivalent & Substitute Parts

Part Overview

The RC6432F1821CS is a 1.82 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package format. This thick film resistor features moisture resistance and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are required for design flexibility, inventory management, or supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F1821CS is determined by strict equivalence across the following parameters: resistance value (1.82 kOhms), tolerance (±1%), power rating (1W), package format (2512 / 6432 Metric), temperature coefficient (±100ppm/°C), operating temperature range (-55°C ~ 155°C), composition (thick film), and compliance certifications (ROHS3, REACH Unaffected). All identified substitute parts meet these core electrical and mechanical requirements. Variations in physical dimensions within the 2512 package specification, packaging format (tape & reel versus bulk), and optional automotive qualification (AEC-Q200) do not preclude substitution when the primary electrical parameters remain equivalent.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts—CRCW25121K82FKEG (Vishay Dale), ERJ-1TNF1821U (Panasonic), and RMCF2512FT1K82 (Stackpole)—satisfy the core electrical and mechanical requirements for direct substitution with the RC6432F1821CS.

CRCW25121K82FKEG and RMCF2512FT1K82 maintain Active product status, ensuring long-term availability and continued manufacturing support. Both incorporate automotive AEC-Q200 qualification, providing additional reliability assurance for applications requiring automotive-grade components.

ERJ-1TNF1821U carries a "Not For New Designs" designation, indicating that while the part remains functionally equivalent and currently in stock, Panasonic does not recommend its selection for new design implementations. This status should be considered in applications requiring extended product lifecycle support.

All substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity level (MSL 1), matching the environmental and regulatory requirements of the primary part.

Frequently Asked Questions (FAQ)

Q: Can CRCW25121K82FKEG replace RC6432F1821CS in existing designs?

A: Yes. Both parts share identical electrical specifications (1.82 kOhms, ±1%, 1W, ±100ppm/°C) and operate across the same temperature range (-55°C ~ 155°C). Both are packaged in the 2512 (6432 Metric) format with two terminations. Physical dimensions vary slightly within the 2512 specification tolerance, but this does not affect PCB footprint compatibility.

Q: What is the difference between the Samsung RC6432F1821CS and Stackpole RMCF2512FT1K82?

A: The parts are electrically and mechanically equivalent. The primary distinction is manufacturer and packaging format. RMCF2512FT1K82 includes automotive AEC-Q200 qualification and is supplied in tape & reel format, whereas RC6432F1821CS features moisture resistance specification and is supplied in bulk packaging. Both maintain Active product status and ROHS3 compliance.

Q: Why is ERJ-1TNF1821U marked "Not For New Designs"?

A: The "Not For New Designs" status indicates that Panasonic has discontinued active promotion of this part for new applications. While ERJ-1TNF1821U remains functionally equivalent and currently available in inventory, designs should prioritize parts with Active status (CRCW25121K82FKEG or RMCF2512FT1K82) for applications requiring extended product lifecycle support.

Q: Are there packaging format differences between substitute parts?

A: Yes. RC6432F1821CS is supplied in bulk packaging, while CRCW25121K82FKEG, ERJ-1TNF1821U, and RMCF2512FT1K82 are supplied in tape & reel (TR) format. Tape & reel packaging is standard for automated assembly processes. Bulk packaging may require manual handling or reel conversion. This distinction does not affect electrical or mechanical compatibility.

Q: Do all substitute parts meet the same compliance requirements?

A: Yes. All parts—RC6432F1821CS, CRCW25121K82FKEG, ERJ-1TNF1821U, and RMCF2512FT1K82—are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99. All maintain MSL 1 (unlimited moisture sensitivity level). Compliance certifications are equivalent across all options.

Q: What is the significance of AEC-Q200 qualification on substitute parts?

A: AEC-Q200 is an automotive industry qualification standard for passive components. CRCW25121K82FKEG and RMCF2512FT1K82 carry this certification, indicating enhanced reliability testing and suitability for automotive applications. RC6432F1821CS does not list AEC-Q200 qualification but specifies moisture resistance. The presence or absence of AEC-Q200 does not affect substitution eligibility for non-automotive applications.
