Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F2872CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (28.7 kOhms), tolerance (±1%), power rating (1W), and temperature coefficient (±100ppm/°C) must match exactly. These parameters define the functional performance of the resistor in circuit applications.

Mechanical Compatibility: Package format (2512 / 6432 Metric), number of terminations (2), and physical dimensions must be compatible with the PCB layout and assembly process. Dimensional variations within supplier tolerances are acceptable.

Environmental & Compliance Requirements: Operating temperature range (-55°C ~ 155°C), RoHS3 compliance, and MSL rating (1 - Unlimited) establish the reliability and regulatory framework for the component.

The identified substitute part ERJ-1TNF2872U from Panasonic Electronic Components satisfies all electrical and mechanical parameters. However, product status differences and application-specific certifications must be evaluated during component selection.

Engineering Selection Recommendations

For Active Production Programs: The RC6432F2872CS is the primary selection due to its Active product status and current inventory availability (694 units in stock). This part is suitable for new designs and ongoing production requirements.

For Automotive Applications: The ERJ-1TNF2872U from Panasonic provides AEC-Q200 automotive qualification, which is not specified for the Samsung part. If automotive-grade certification is a design requirement, the Panasonic substitute is the appropriate choice despite its "Not For New Designs" status. This designation typically indicates the manufacturer is transitioning the product line but does not preclude its use in existing or new automotive programs with proper qualification.

Dimensional Considerations: The ERJ-1TNF2872U exhibits slightly larger physical dimensions (0.252" L x 0.126" W vs. 0.248" L x 0.126" W) and greater seated height (0.028" vs. 0.026"). PCB layout verification is required to confirm clearance compatibility before substitution.

Packaging Format: The Samsung part packaging format is not specified in the provided data. The Panasonic substitute is supplied in Tape & Reel (TR) format. Confirm packaging compatibility with assembly equipment and procurement requirements.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF2872U be used as a direct replacement for RC6432F2872CS in all applications?

A: Electrical and thermal performance are equivalent due to matching resistance, tolerance, power rating, and temperature coefficient specifications. However, the slightly larger physical dimensions of the Panasonic part require PCB layout verification. The "Not For New Designs" status of the Panasonic part should be evaluated against your program timeline and supply chain strategy.

Q: What is the significance of the AEC-Q200 certification on the ERJ-1TNF2872U?

A: AEC-Q200 is an automotive industry qualification standard for passive components. This certification is relevant only if your application requires automotive-grade reliability and traceability. The Samsung RC6432F2872CS does not carry this specification.

Q: Are there dimensional compatibility issues between these two parts?

A: The ERJ-1TNF2872U is 0.004" (0.10mm) longer and 0.002" (0.04mm) taller than the RC6432F2872CS. Both parts use the same 2512 package format and footprint. Verify PCB design clearances, particularly for height-constrained applications or high-density layouts.

Q: What does "Not For New Designs" mean for the Panasonic part?

A: This status indicates the manufacturer is phasing out the product line. The part remains available for existing applications but is not recommended for new program starts. Evaluate long-term supply availability and consider the Samsung part for new designs requiring extended production support.

Q: Are both parts RoHS3 compliant?

A: Yes. Both RC6432F2872CS and ERJ-1TNF2872U are ROHS3 compliant with unlimited moisture sensitivity (MSL 1), meeting current environmental and regulatory requirements.
