RC6432F8452CS Equivalent & Substitute Parts

Part Overview

The RC6432F8452CS is a 84.5 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package. This thick film, moisture-resistant component is designed for general-purpose applications requiring precision resistive elements with moderate power dissipation. The part maintains Active product status with 689 units currently in stock.

Substitute parts become necessary when the primary manufacturer experiences supply constraints, when design requirements mandate specific certifications such as automotive qualification, or when alternative sourcing strategies are implemented to optimize procurement and inventory management.

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F8452CS is determined by strict equivalence across the following parameters:

• Resistance value: 84.5 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 1W (exact match required)
• Package: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature coefficient: ±100ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Moisture sensitivity level: 1 (Unlimited) (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The ERJ-1TNF8452U from Panasonic Electronic Components meets all mandatory electrical and mechanical parameters. This substitute maintains identical resistance, tolerance, power rating, package configuration, and environmental specifications. The primary distinction is the addition of AEC-Q200 automotive qualification and a change in product status to Not For New Designs.

Engineering Selection Recommendations

The RC6432F8452CS maintains Active product status and is the preferred selection for new designs requiring standard thick film 84.5 kOhms 1W resistors in the 2512 package. This part is suitable for general-purpose applications without automotive qualification requirements.

The ERJ-1TNF8452U serves as a functional equivalent for applications where AEC-Q200 automotive qualification is mandated or where Panasonic sourcing is strategically preferred. However, this part carries Not For New Designs status, indicating that Panasonic is discontinuing this specific model. Selection of the ERJ-1TNF8452U should be limited to legacy design support, automotive applications with existing qualification documentation, or temporary supply mitigation when the primary part is unavailable.

For new designs without automotive requirements, the RC6432F8452CS is the recommended choice. For automotive applications, alternative qualified resistors meeting AEC-Q200 standards should be evaluated from the ERJ-1TNF8452U secondary substitute list.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF8452U be used as a direct replacement for RC6432F8452CS in all applications?

A: Yes, from an electrical and mechanical standpoint. Both parts share identical resistance (84.5 kOhms), tolerance (±1%), power rating (1W), package (2512), composition (thick film), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). However, the ERJ-1TNF8452U carries Not For New Designs status, making it unsuitable for new product development. Use only for legacy support or when the primary part is unavailable.

Q: What is the significance of the dimensional differences between these parts?

A: The ERJ-1TNF8452U has slightly larger dimensions (0.252" L vs. 0.248" L and 0.028" height vs. 0.026" height). These minor variations remain within typical PCB layout tolerances for 2512 package components but should be verified against specific board design constraints, particularly in space-constrained applications.

Q: Why does the ERJ-1TNF8452U have AEC-Q200 qualification while the RC6432F8452CS does not?

A: AEC-Q200 is an automotive industry qualification standard. Panasonic manufactures the ERJ-1TNF8452U to meet automotive reliability requirements, while Samsung's RC6432F8452CS is specified for general-purpose applications. Selection depends on application requirements, not interchangeability.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the RC6432F8452CS and ERJ-1TNF8452U are ROHS3 Compliant and suitable for applications requiring lead-free, halogen-free construction.

Q: What packaging formats are available?

A: The RC6432F8452CS packaging format is not specified in the provided data. The ERJ-1TNF8452U is supplied in Tape & Reel (TR) format, which is standard for automated assembly processes.
