RC6432F3653CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F3653CS is a 365 kOhms ±1% 1W chip resistor manufactured by Samsung Electro-Mechanics in the 2512 (6432 Metric) package format. This thick film resistor is designed for general-purpose applications requiring moisture resistance and operates across the temperature range of -55°C to 155°C. The component is currently in active production status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the original component requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F3653CS is determined by strict alignment of the following critical parameters:

Electrical Parameters (Must Match Exactly):

• Resistance value: 365 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C

Mechanical Parameters (Must Match):

• Package format: 2512 (6432 Metric)
• Number of terminations: 2
• Composition: Thick Film

Compliance Parameters (Must Match or Exceed):

• RoHS Status: ROHS3 Compliant minimum
• Moisture Sensitivity Level: 1 (Unlimited) minimum

The CRCW2512365KFKEG manufactured by Vishay Dale meets all substitution criteria. Both components share identical electrical specifications, mechanical dimensions within acceptable tolerances, and equivalent compliance certifications. The Vishay component includes additional AEC-Q200 automotive qualification, which does not restrict its use in non-automotive applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F3653CS and CRCW2512365KFKEG are active production components with ROHS3 compliance and identical electrical performance specifications. Selection between these parts should be based on:

Availability and Lead Time: The CRCW2512365KFKEG currently has higher inventory availability (1761 Pcs) compared to the RC6432F3653CS (762 Pcs), which may influence procurement decisions for high-volume applications.

Packaging Format: The RC6432F3653CS is supplied in standard packaging, while the CRCW2512365KFKEG is available in Tape & Reel (TR) format, which is preferred for automated assembly processes.

Automotive Qualification: The CRCW2512365KFKEG carries AEC-Q200 automotive qualification. This certification does not restrict use in non-automotive applications and may provide additional quality assurance documentation for critical applications.

Mechanical Tolerances: Dimensional variations between the two parts (width 0.126" vs 0.124", height 0.026" vs 0.028") are within standard PCB design tolerances and do not affect functional compatibility in standard 2512 footprints.

Frequently Asked Questions (FAQ)

Q: Can the CRCW2512365KFKEG directly replace the RC6432F3653CS on existing PCBs?

A: Yes. Both components use the 2512 (6432 Metric) package with identical pin spacing and electrical specifications. Dimensional variations are within standard PCB design tolerances and do not require footprint modifications.

Q: Does the AEC-Q200 rating on the Vishay component affect its use in non-automotive applications?

A: No. AEC-Q200 is an additional qualification that indicates automotive-grade reliability. This certification does not restrict the component's use in general-purpose, industrial, or consumer applications.

Q: Are the moisture resistance characteristics equivalent between these two parts?

A: Yes. Both components have Moisture Sensitivity Level 1 (Unlimited), indicating equivalent moisture resistance performance and identical handling requirements.

Q: What is the significance of the ±100ppm/°C temperature coefficient for both parts?

A: The temperature coefficient specifies the maximum resistance change per degree Celsius across the operating range. Both parts maintain identical stability characteristics across the -55°C to 155°C operating window.

Q: Can these parts be used interchangeably in automated assembly processes?

A: The CRCW2512365KFKEG in Tape & Reel format is optimized for automated pick-and-place assembly. The RC6432F3653CS in standard packaging may require manual handling or reel conversion, depending on assembly line configuration.

Q: Are there any compliance or certification differences that would affect component selection?

A: Both components are ROHS3 compliant and REACH unaffected. The CRCW2512365KFKEG includes additional AEC-Q200 automotive qualification, which provides supplementary quality documentation without restricting application scope.
