Key Parameters

Substitute Part Grouping Explanation

Substitution of the RC6432J363CS is determined by strict equivalence in the following parameters:

Critical Parameters (Must Match):

• Resistance value: 36 kOhms
• Power rating: 1W
• Package / Case: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±100ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Moisture Sensitivity Level: 1 (Unlimited)
• RoHS Status: ROHS3 Compliant

Allowable Variation:

• Tolerance: Substitute parts may have tighter tolerance (±1%) than the original specification (±5%). Tighter tolerance is functionally compatible and represents an upgrade in precision.
• Packaging format: Tape & Reel (TR) is compatible with the component specification and represents a packaging variation only.

The ERJ-1TNF3602U from Panasonic Electronic Components meets all critical parameters and is identified as a direct substitute. This part maintains identical resistance, power rating, package dimensions, temperature characteristics, and compliance certifications while offering improved tolerance specification (±1% versus ±5%).

Parameter Comparison

Engineering Selection Recommendations

RC6432J363CS (Samsung Electro-Mechanics): Select this part for new designs requiring active production status and standard industrial applications. The part is currently in active production with adequate inventory (704 units). It meets all ROHS3 and REACH compliance requirements for non-automotive applications.

ERJ-1TNF3602U (Panasonic Electronic Components): This substitute is suitable for applications where tighter tolerance (±1%) is beneficial or where automotive-grade qualification (AEC-Q200) is required. However, this part carries "Not For New Designs" status, indicating it is in mature or declining production phase. Use this substitute only when existing designs require component replacement or when automotive qualification is a mandatory requirement. Inventory availability is higher (5007 units), supporting legacy system support and maintenance applications.

Dimensional Compatibility: Both parts fit the 2512 package specification. The ERJ-1TNF3602U exhibits slightly larger dimensions (0.252" L vs. 0.248" L and 0.028" height vs. 0.026" height). Verify PCB layout clearances in space-constrained applications before substitution.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF3602U replace RC6432J363CS in existing designs?

A: Yes. The ERJ-1TNF3602U is electrically and mechanically compatible. Both parts share identical resistance (36 kOhms), power rating (1W), package type (2512), temperature range (-55°C ~ 155°C), and compliance certifications (ROHS3, MSL 1). The substitute offers improved tolerance (±1% vs. ±5%), which is functionally superior. Verify PCB layout accommodates the slightly larger dimensions (0.252" L x 0.028" height maximum).

Q: What is the significance of "Not For New Designs" status on the ERJ-1TNF3602U?

A: This designation indicates the part is in mature production phase and may be subject to discontinuation. It is suitable for replacement, repair, and maintenance of existing systems but should not be selected for new product development. For new designs, the RC6432J363CS (active status) is the preferred choice.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist. RC6432J363CS: 0.248" L x 0.126" W, 0.026" height maximum. ERJ-1TNF3602U: 0.252" L x 0.126" W, 0.028" height maximum. Both conform to the 2512 package specification. Verify PCB footprint and clearance requirements, particularly in high-density layouts.

Q: Does the ERJ-1TNF3602U automotive qualification (AEC-Q200) affect substitution?

A: AEC-Q200 qualification is an additional certification that does not conflict with standard industrial applications. If the original design does not require automotive qualification, the presence of AEC-Q200 on the substitute part does not create incompatibility. If automotive qualification is required, the ERJ-1TNF3602U meets this requirement while the RC6432J363CS does not.

Q: What is the tolerance difference impact?

A: The RC6432J363CS has ±5% tolerance; the ERJ-1TNF3602U has ±1% tolerance. In circuit applications where resistance value precision is critical, the tighter tolerance of the substitute is advantageous. In applications where ±5% tolerance is acceptable, both parts perform identically. No circuit redesign is required when substituting with the tighter tolerance part.

Q: Are packaging formats (Tape & Reel vs. standard) compatible?

A: Yes. Tape & Reel (TR) is a packaging and delivery format only. It does not affect component electrical or mechanical specifications. Both formats contain identical components suitable for automated assembly processes.
