RC6432F3010CS Equivalent & Substitute Parts Reference

Part Overview

The RC6432F3010CS is a 301 Ohms ±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 maintains ROHS3 compliance with MSL 1 rating. The part is currently in active production status with 879 pieces available in new original inventory. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications align with the original component, enabling direct replacement in applications where the primary part becomes unavailable or when alternative sourcing is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F3010CS is determined by strict alignment of the following critical parameters:

Electrical Specifications: Resistance value (301 Ohms), tolerance (±1%), and power rating (1W) must be identical. Temperature coefficient (±100ppm/°C) and operating temperature range (-55°C ~ 155°C) establish thermal performance boundaries that cannot be compromised.

Mechanical Compatibility: Package format must be 2512 (6432 Metric) to ensure physical fit within PCB footprints and assembly equipment compatibility. Physical dimensions and termination count (2) must match or be within acceptable manufacturing tolerances.

Composition & Construction: Thick film construction is the specified technology. Moisture resistance characteristics and composition type determine long-term reliability in target environments.

Compliance & Certifications: ROHS3 compliance and MSL 1 rating are mandatory for equivalent substitution. These certifications confirm environmental and handling requirements alignment.

The CRCW2512301RFKEG from Vishay Dale meets all substitution criteria through identical electrical parameters, matching package specification, equivalent thick film construction, and matching compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F3010CS and CRCW2512301RFKEG are active production components with ROHS3 compliance and MSL 1 ratings. The RC6432F3010CS features moisture-resistant thick film construction, while the CRCW2512301RFKEG carries AEC-Q200 automotive qualification. Selection between these parts depends on application requirements: the Samsung component is suitable for general industrial and consumer applications requiring moisture resistance, while the Vishay Dale component is specified for automotive environments where AEC-Q200 qualification is mandated. Both components satisfy identical electrical and thermal specifications, enabling direct substitution based on supply availability and application-specific compliance requirements. Dimensional variations (width 3.20mm vs 3.15mm, height 0.66mm vs 0.70mm) fall within standard PCB footprint tolerances for 2512 package format and do not restrict interchangeability.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512301RFKEG directly replace RC6432F3010CS in existing designs?

A: Yes. Both components share identical electrical specifications (301 Ohms ±1%, 1W), matching package format (2512), equivalent thermal performance (-55°C ~ 155°C, ±100ppm/°C), and equivalent compliance certifications (ROHS3, MSL 1). Dimensional tolerances are within standard PCB footprint specifications for this package class.

Q: What is the significance of AEC-Q200 qualification on the Vishay Dale part?

A: AEC-Q200 is an automotive industry qualification standard. The CRCW2512301RFKEG carries this certification, making it suitable for automotive applications where this qualification is contractually required. The RC6432F3010CS does not carry this designation and is not specified for automotive use.

Q: Are there packaging differences between these parts?

A: The RC6432F3010CS is supplied in standard packaging format. The CRCW2512301RFKEG is supplied in Tape & Reel (TR) format, which is standard for high-volume automated assembly. Both formats contain identical components; packaging format affects only handling and assembly processes, not component performance.

Q: Do the minor dimensional differences affect PCB compatibility?

A: No. Width variation (3.20mm vs 3.15mm) and height variation (0.66mm vs 0.70mm) are within standard manufacturing tolerances for 2512 package format. Both components fit standard 2512 PCB footprints without modification.

Q: What does MSL 1 rating mean for handling?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. Both components can be stored and handled under standard industrial conditions without special desiccant packaging or baking procedures prior to assembly.

Q: Are both parts currently available?

A: The RC6432F3010CS has 879 pieces in new original inventory. The CRCW2512301RFKEG has 3300 pieces in new original inventory. Availability status should be confirmed with current suppliers for time-sensitive procurement.
