Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F4643CS are identified based on strict electrical and mechanical parameter alignment. The substitution criteria are:

Mandatory Matching Parameters:

• Resistance value: 464 kOhms (exact match required)
• Tolerance: ±1% (substitute must equal or exceed precision)
• Power rating: 1W (substitute must equal or exceed)
• Package format: 2512 (6432 Metric) (exact match for PCB footprint compatibility)
• Composition: Thick Film (determines electrical behavior)
• Temperature coefficient: ±100ppm/°C (substitute must equal or be lower)
• Operating temperature range: -55°C ~ 155°C (substitute must equal or exceed)

Compliance Requirements:

• RoHS3 Compliant status required
• Moisture Sensitivity Level MSL 1 (Unlimited) acceptable
• REACH Unaffected status acceptable

The CRCW2512464KFKEG from Vishay Dale meets all mandatory electrical and mechanical parameters while maintaining equivalent compliance certifications. The primary distinction is the addition of AEC-Q200 automotive qualification in the substitute part, which represents an enhanced specification level suitable for automotive applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RC6432F4643CS and CRCW2512464KFKEG are Active status components with full RoHS3 compliance and REACH Unaffected designation, making them suitable for current production environments.

RC6432F4643CS (Samsung Electro-Mechanics) is appropriate for general-purpose applications where moisture resistance is a primary design consideration. Current inventory of 793 units supports immediate availability for standard applications.

CRCW2512464KFKEG (Vishay Dale) provides equivalent electrical and mechanical performance with the addition of AEC-Q200 automotive qualification. This enhanced specification is applicable to automotive-grade designs or applications requiring automotive-level reliability standards. Higher inventory availability (2,976 units) supports extended production runs. The Tape & Reel packaging format is standard for automated assembly processes.

Selection between these parts should be based on application requirements: general-purpose designs may use either part, while automotive or automotive-grade applications should specify the CRCW2512464KFKEG variant.

Frequently Asked Questions (FAQ)

Q: Can CRCW2512464KFKEG be used as a direct replacement for RC6432F4643CS?

A: Yes. Both components share identical electrical specifications (464 kOhms, ±1%, 1W), identical package format (2512/6432 Metric), and equivalent compliance certifications (RoHS3, REACH Unaffected). Physical dimensions are compatible within standard PCB assembly tolerances. The CRCW2512464KFKEG includes AEC-Q200 automotive qualification, which does not restrict use in non-automotive applications.

Q: What are the dimensional differences between these parts?

A: Length is identical at 0.248" (6.30mm). Width differs by 0.002" (0.15mm): RC6432F4643CS is 0.126" (3.20mm) versus CRCW2512464KFKEG at 0.124" (3.15mm). Height differs by 0.002" (0.04mm): RC6432F4643CS is 0.026" (0.66mm) versus CRCW2512464KFKEG at 0.028" (0.70mm). These variations are within standard PCB footprint tolerances and do not affect interchangeability.

Q: Are there any compliance or certification differences?

A: Both parts are RoHS3 Compliant and REACH Unaffected. The CRCW2512464KFKEG carries additional AEC-Q200 automotive qualification. This represents an enhanced specification level and does not create incompatibility with non-automotive applications.

Q: What is the significance of the packaging format difference?

A: RC6432F4643CS is supplied in standard packaging format. CRCW2512464KFKEG is supplied in Tape & Reel (TR) format, which is optimized for automated pick-and-place assembly. Both formats contain identical components; packaging format selection depends on assembly process requirements.

Q: Can these parts be used interchangeably in existing designs?

A: Yes. Identical electrical parameters (resistance, tolerance, power rating, temperature coefficient, operating temperature range) and package format (2512/6432 Metric) ensure functional and mechanical interchangeability. PCB footprints designed for either part will accommodate both without modification.

Q: What is the Moisture Sensitivity Level (MSL) significance?

A: Both parts carry MSL 1 (Unlimited) designation, indicating unlimited shelf life without moisture bake-out requirements. This simplifies inventory management and reduces handling constraints compared to higher MSL ratings.
