RC6432F1822CS Equivalent & Substitute Parts

Part Overview

The RC6432F1822CS is an 18.2 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package. This thick film, moisture-resistant component operates across -55°C to 155°C and is ROHS3 compliant with MSL 1 rating. The part is currently in active production status with 814 units in stock.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained. The ERJ-1TNF1822U from Panasonic Electronic Components provides functional equivalence with identical resistance, tolerance, power rating, and package dimensions, though it carries automotive AEC-Q200 qualification and is marked as not for new designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F1822CS is determined by strict equivalence across the following parameters:

Electrical Equivalence Requirements:

• Resistance value: 18.2 kOhms (exact match)
• Tolerance: ±1% (minimum requirement)
• Power rating: 1W (minimum requirement)
• Temperature coefficient: ±100ppm/°C (maximum deviation)
• Operating temperature range: -55°C to 155°C (minimum coverage)

Mechanical Equivalence Requirements:

• Package type: 2512 (6432 Metric)
• Composition: Thick Film
• Number of terminations: 2

Compliance Requirements:

• RoHS3 compliance (mandatory)
• MSL rating: 1 (Unlimited)

The ERJ-1TNF1822U meets all electrical and mechanical equivalence criteria. Dimensional variations (0.252" L vs. 0.248" L; 0.028" H vs. 0.026" H) remain within standard PCB design tolerances for 2512 package components. The automotive AEC-Q200 qualification represents an additional feature rather than a limiting factor for general industrial applications.

Engineering Selection Recommendations

For Active Production Applications: The RC6432F1822CS is the primary selection for new designs. It maintains active product status with established supply availability (814 units in stock) and full manufacturer support.

For Replacement or Secondary Sourcing: The ERJ-1TNF1822U provides functional equivalence for existing applications requiring component replacement or alternative sourcing. Although marked as "Not For New Designs," it meets all electrical and mechanical specifications for retrofit applications. The automotive AEC-Q200 qualification provides additional reliability assurance for demanding environments.

Compliance Considerations: Both parts maintain ROHS3 compliance and MSL 1 rating, ensuring regulatory compatibility and simplified handling procedures. No additional qualification testing is required when substituting between these parts in applications where the original specification is maintained.

Dimensional Tolerance: The minor dimensional variations (0.004" length difference, 0.002" height difference) fall within standard PCB design tolerances for 2512 package components and do not require layout modifications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF1822U replace RC6432F1822CS in existing designs?

A: Yes. The ERJ-1TNF1822U meets all electrical specifications (18.2 kOhms ±1%, 1W, ±100ppm/°C, -55°C to 155°C) and mechanical requirements (2512 package, thick film composition). Dimensional variations are within standard tolerances for this package class.

Q: What does "Not For New Designs" mean for the ERJ-1TNF1822U?

A: This designation indicates Panasonic has discontinued active development for this part number. It remains available for replacement and retrofit applications but should not be selected for new product development. The RC6432F1822CS is the recommended choice for new designs.

Q: Are there packaging differences between these parts?

A: The RC6432F1822CS is supplied in standard packaging, while the ERJ-1TNF1822U is supplied in Tape & Reel (TR) format. Both are compatible with standard pick-and-place assembly equipment. Tape & Reel packaging may require different handling procedures during storage and assembly.

Q: Do the dimensional differences affect PCB layout?

A: No. The length difference (0.004") and height difference (0.002") are within standard PCB design tolerances for 2512 package components. No layout modifications are required when substituting between these parts.

Q: Is the automotive AEC-Q200 qualification required for my application?

A: AEC-Q200 qualification is not required for general industrial applications. It represents an additional feature of the ERJ-1TNF1822U that provides enhanced reliability assurance for automotive and high-reliability environments. Standard industrial applications do not require this qualification.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RC6432F1822CS and ERJ-1TNF1822U are ROHS3 compliant with MSL 1 (Unlimited) rating. No additional compliance verification is required when substituting between these parts.

Q: What is the temperature coefficient significance?

A: Both parts share an identical ±100ppm/°C temperature coefficient, ensuring equivalent resistance stability across the full -55°C to 155°C operating range. This parameter is critical for precision circuit applications and is maintained in the substitute part.
