RC6432F914CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F914CS is a 910 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 1016 units available in inventory.

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.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F914CS is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 910 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Package format: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Termination count: 2

Compliance Parameters:

• RoHS3 compliance status
• Moisture Sensitivity Level 1 classification
• REACH unaffected status

The ERJ-1TNF9103U manufactured by Panasonic Electronic Components satisfies all mandatory matching parameters and compliance requirements. This substitute maintains identical electrical specifications and mechanical compatibility while offering automotive AEC-Q200 qualification. The dimensional variance (0.252" L x 0.126" W versus 0.248" L x 0.126" W, and height difference of 0.028" versus 0.026") remains within standard PCB layout tolerances for 2512 package footprints.

Parameter Comparison

Engineering Selection Recommendations

Primary Part Selection (RC6432F914CS): The RC6432F914CS is the preferred selection for new designs. This component maintains active production status, ensuring long-term availability and supply chain stability. The part is ROHS3 compliant and carries unlimited moisture sensitivity classification, suitable for standard industrial and commercial applications.

Substitute Part Selection (ERJ-1TNF9103U): The ERJ-1TNF9103U serves as a direct functional equivalent when supply of the primary part is constrained. This Panasonic component is qualified to automotive AEC-Q200 standards, providing enhanced reliability documentation for applications requiring automotive-grade components. However, the part carries a "Not For New Designs" status, indicating that Panasonic has transitioned this model to mature production phase. Selection of this substitute should be limited to legacy design support or applications where automotive qualification is a specific requirement.

Both parts maintain identical electrical performance, thermal characteristics, and mechanical compatibility within standard PCB assembly tolerances.

Frequently Asked Questions (FAQ)

Q: Can ERJ-1TNF9103U be used as a direct replacement for RC6432F914CS in existing designs?

A: Yes. Both components share identical resistance (910 kOhms), tolerance (±1%), power rating (1W), package format (2512), temperature coefficient (±100ppm/°C), and operating temperature range (-55°C ~ 155°C). Dimensional differences (length 0.252" versus 0.248", height 0.028" versus 0.026") fall within standard PCB layout tolerances for this package class.

Q: What is the significance of the "Not For New Designs" status on the ERJ-1TNF9103U?

A: This designation indicates that Panasonic has classified this part as mature production. While the component remains fully functional and available, Panasonic recommends that new design projects select alternative current-generation parts. Existing designs and legacy applications may continue using this part without technical restriction.

Q: Does the ERJ-1TNF9103U automotive AEC-Q200 qualification apply to all applications?

A: AEC-Q200 qualification is a specific automotive industry standard. This certification is relevant only for applications requiring automotive-grade component documentation. Non-automotive applications do not require this qualification and may select either part based on availability and supply chain considerations.

Q: Are there dimensional constraints when substituting between these parts?

A: The dimensional variance between RC6432F914CS and ERJ-1TNF9103U is minimal. Length differs by 0.004" (0.10mm) and height by 0.002" (0.04mm). Standard PCB design practices for 2512 package footprints accommodate these variations. Verify footprint clearances in high-density layouts or applications with tight mechanical constraints.

Q: What compliance certifications apply to both parts?

A: Both components are ROHS3 compliant, REACH unaffected, and classified as Moisture Sensitivity Level 1 (unlimited). Both carry ECCN EAR99 and HTSUS 8533.21.0030 classifications for export and tariff purposes.
