RC6432F8453CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F8453CS is a 845 kOhms ±1% 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 1118 units available in inventory.

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained. The primary substitute identified is the ERJ-1TNF8453U from Panasonic Electronic Components, which shares identical resistance, tolerance, power rating, and package dimensions while offering automotive-grade AEC-Q200 qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F8453CS is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Resistance value: 845 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Specifications:

• Package format: 2512 (6432 Metric)
• Composition: Thick Film
• Number of terminations: 2
• Moisture sensitivity level: 1 (Unlimited)

Compliance Requirements:

• RoHS3 compliance
• REACH unaffected status

The ERJ-1TNF8453U from Panasonic meets all substitution criteria with identical electrical and mechanical parameters. The primary distinction is product status and automotive qualification level, which does not preclude substitution in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

RC6432F8453CS (Samsung Electro-Mechanics): Select this part for new designs requiring active production status and long-term availability. The component is ROHS3 compliant and carries unlimited moisture sensitivity rating. Current inventory of 1118 units supports production requirements.

ERJ-1TNF8453U (Panasonic Electronic Components): This substitute is electrically and mechanically equivalent with identical electrical specifications and package dimensions. The part carries AEC-Q200 automotive qualification, which provides additional reliability assurance for applications requiring automotive-grade components. However, the product status is listed as "Not For New Designs," indicating Panasonic is transitioning this part. Use this substitute only when automotive qualification is a design requirement or when Samsung part availability is constrained. Tape & Reel packaging is suitable for automated assembly processes.

Both parts are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF8453U be used as a direct replacement for RC6432F8453CS?

A: Yes, within the constraints of product status. Both parts share identical electrical specifications (845 kOhms ±1%, 1W), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and package format (2512 / 6432 Metric). Physical dimensions vary slightly (length 6.30mm vs 6.40mm, height 0.66mm vs 0.70mm), which remains within standard PCB layout tolerances for 2512 packages. The primary consideration is that ERJ-1TNF8453U is marked "Not For New Designs."

Q: What are the key parameters that determine substitution eligibility?

A: Substitution is determined by equivalence in: resistance value (845 kOhms), tolerance (±1%), power rating (1W), package format (2512), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance status (ROHS3, REACH unaffected). Deviations in any of these parameters disqualify a part as a direct substitute.

Q: Are there packaging differences between these parts?

A: Yes. RC6432F8453CS is supplied in bulk packaging, while ERJ-1TNF8453U is supplied in Tape & Reel (TR) format. Tape & Reel packaging is optimized for automated pick-and-place assembly, while bulk packaging is suitable for manual assembly or lower-volume applications. This difference does not affect electrical or mechanical compatibility.

Q: What is the significance of the "Not For New Designs" status on the Panasonic part?

A: This status indicates that Panasonic is discontinuing or has discontinued this part for new design applications. While the part remains functionally equivalent and available in current inventory (1060 units), it should not be selected for new product development. Use this part only as a substitute when the Samsung part is unavailable or when existing designs require component replacement.

Q: Do both parts meet current environmental compliance requirements?

A: Yes. Both RC6432F8453CS and ERJ-1TNF8453U are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards for electronic components in most jurisdictions.
