Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F184CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (180 kOhms), tolerance (±1%), power rating (1W), and temperature coefficient (±100ppm/°C) must match exactly.

Mechanical Compatibility: Package designation (2512 / 6432 Metric) and physical dimensions must be equivalent to ensure PCB footprint compatibility and assembly process alignment.

Environmental & Compliance Requirements: Operating temperature range (-55°C ~ 155°C), moisture resistance capability, RoHS3 compliance, and MSL 1 rating must be maintained.

Composition & Construction: Thick film construction type ensures consistent performance characteristics across thermal cycling and operational stress conditions.

The RC2512FK-07180KL manufactured by YAGEO satisfies all substitution criteria through identical electrical parameters, equivalent mechanical dimensions within tolerance, and matching compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F184CS and RC2512FK-07180KL are active production components with full ROHS3 compliance and REACH unaffected status. Selection between these parts is based on availability, packaging format, and supply chain requirements rather than functional or compliance differences.

The RC6432F184CS from Samsung Electro-Mechanics is suitable for applications requiring Samsung-qualified components or where existing supply agreements specify Samsung sourcing.

The RC2512FK-07180KL from YAGEO provides equivalent functionality with higher current inventory availability (9031 units versus 1026 units). This part is supplied in Tape & Reel (TR) packaging format, which is standard for automated assembly processes.

Both components maintain identical electrical performance, thermal characteristics, and environmental ratings. Physical dimensions are within standard PCB design tolerances for the 2512 package class. No design modifications or re-qualification are required when substituting between these parts.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-07180KL replace RC6432F184CS in existing designs?

A: Yes. Both parts share identical electrical specifications (180 kOhms ±1%, 1W, ±100ppm/°C), operate across the same temperature range (-55°C ~ 155°C), and are packaged in the 2512 (6432 Metric) format. Physical dimensions are compatible within standard PCB design tolerances. No circuit modifications are required.

Q: What are the dimensional differences between these parts?

A: Length differs by 0.002" (0.05mm), width by 0.004" (0.10mm), and height by 0.001" (0.01mm). These variations are within standard manufacturing tolerances for the 2512 package and do not affect PCB footprint compatibility or assembly processes.

Q: Are both parts RoHS compliant?
