RC6432J824CS Equivalent & Substitute Parts

Part Overview

The RC6432J824CS is a 820 kOhms ±5% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package format. This thick film, moisture-resistant component operates across the temperature range of -55°C to 155°C and is ROHS3 compliant. The part is currently in active production status with 921 pieces available in inventory.

Equivalent and substitute parts are identified when applications require alternative sourcing due to inventory constraints, supply chain considerations, or specific design requirements that align with the established electrical and mechanical parameters of this resistor category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC6432J824CS is determined by strict adherence to the following electrical and mechanical parameters:

Critical Matching Parameters:

• Resistance value: 820 kOhms
• Power rating: 1W
• Package format: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Number of terminations: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

Allowable Variation:

• Tolerance may be tighter (lower tolerance value) than the original ±5% specification, as this represents improved accuracy without compromising functionality
• Physical dimensions may vary within standard manufacturing tolerances for the 2512 package format

The ERJ-1TNF8203U from Panasonic Electronic Components meets all critical matching parameters while offering a tighter tolerance specification of ±1% in place of the original ±5%.

Engineering Selection Recommendations

RC6432J824CS (Samsung Electro-Mechanics): The primary component is recommended for new designs. This part maintains active production status, ensuring long-term availability and supply chain stability. The part is ROHS3 compliant and carries unlimited moisture sensitivity rating, suitable for standard industrial and commercial applications.

ERJ-1TNF8203U (Panasonic Electronic Components): This substitute part is electrically and mechanically compatible with the RC6432J824CS. The ERJ-1TNF8203U provides a tighter tolerance specification (±1% versus ±5%), which may benefit applications requiring improved accuracy. However, this part carries a "Not For New Designs" status, indicating it is in mature or declining production phase. The part includes AEC-Q200 automotive qualification, which is not a requirement for the original part but does not preclude its use in non-automotive applications. Physical dimensions show minor variations within standard 2512 package tolerances.

Selection between these parts should be based on availability requirements, tolerance specifications needed for the application, and supply chain considerations rather than functional performance differences.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-1TNF8203U directly replace the RC6432J824CS in existing designs?

A: Yes. Both parts share identical resistance value (820 kOhms), power rating (1W), package format (2512), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). The ERJ-1TNF8203U features a tighter tolerance (±1% versus ±5%), which represents improved accuracy. Physical dimensions vary within standard manufacturing tolerances for the 2512 package format.

Q: What is the significance of the tolerance difference between these parts?

A: The RC6432J824CS specifies ±5% tolerance, while the ERJ-1TNF8203U specifies ±1% tolerance. Tighter tolerance indicates more precise resistance values. Applications requiring strict resistance accuracy may benefit from the ERJ-1TNF8203U. Applications with tolerance requirements of ±5% or greater will function identically with either part.

Q: Are there compliance or certification differences between these parts?

A: Both parts are ROHS3 compliant and carry unlimited moisture sensitivity rating (MSL 1). The ERJ-1TNF8203U includes AEC-Q200 automotive qualification, which the RC6432J824CS does not specify. This qualification is not required for standard applications but indicates additional quality and reliability testing.

Q: What does "Not For New Designs" status mean for the ERJ-1TNF8203U?

A: This status indicates the part is in mature production phase and may have limited future availability. For new product designs with long-term production requirements, the RC6432J824CS is the preferred choice due to its active production status.

Q: Are the physical dimensions identical between these parts?

A: Physical dimensions show minor variations. The RC6432J824CS measures 0.248" L × 0.126" W × 0.026" H (6.30mm × 3.20mm × 0.66mm). The ERJ-1TNF8203U measures 0.252" L × 0.126" W × 0.028" H (6.40mm × 3.20mm × 0.70mm). These variations fall within standard manufacturing tolerances for the 2512 package format and do not affect PCB layout compatibility.

Q: What packaging formats are available for these parts?

A: The RC6432J824CS is available in standard packaging format. The ERJ-1TNF8203U is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes.
