Substitute Part Grouping Explanation

Substitution eligibility for the RC6432F6811CS is determined by strict equivalence across the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 6.81 kOhms
• Tolerance: ±1%
• Power rating: 1W
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Equivalence Requirements:

• Package classification: 2512 (6432 Metric)
• Number of terminations: 2
• Physical dimensions within tolerance band for 2512 package

Compliance Requirements:

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

All identified substitute parts meet these criteria. The RC2512FK-076K81L (YAGEO) qualifies as a direct equivalent with identical electrical and mechanical specifications. The CRCW25126K81FKEG (Vishay Dale) qualifies as a functionally equivalent substitute with additional automotive AEC-Q200 qualification, suitable for applications requiring enhanced reliability standards.

Parameter Comparison

Engineering Selection Recommendations

RC2512FK-076K81L (YAGEO) is the primary direct substitute for RC6432F6811CS. Both parts maintain identical electrical specifications, temperature performance, and compliance certifications. The YAGEO part is available in Tape & Reel packaging format with 8729 units in stock, providing enhanced procurement availability compared to the Samsung original. Physical dimensions remain within the 2512 package specification tolerance band (6.35mm L x 3.10mm W versus 6.30mm L x 3.20mm W for the Samsung part).

CRCW25126K81FKEG (Vishay Dale) serves as a functionally equivalent substitute with additional automotive AEC-Q200 qualification. This part is suitable for applications requiring automotive-grade reliability standards. The Vishay part maintains all core electrical and thermal specifications while offering enhanced qualification documentation. Physical dimensions (6.30mm L x 3.15mm W) align with the 2512 package standard. Stock availability is 6964 units in Tape & Reel format.

Both substitute parts are active production items with full RoHS3 compliance and REACH unaffected status, matching the regulatory posture of the original Samsung component.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-076K81L replace RC6432F6811CS in existing designs?

A: Yes. The RC2512FK-076K81L maintains identical electrical specifications (6.81 kOhms ±1%, 1W, ±100ppm/°C) and operates across the same temperature range (-55°C to 155°C). Both parts are classified as 2512 (6432 Metric) package with equivalent moisture sensitivity ratings. Physical dimensions fall within acceptable tolerance for the 2512 package footprint.

Q: What is the difference between the YAGEO and Vishay substitutes?

A: The RC2512FK-076K81L (YAGEO) is a direct electrical and mechanical equivalent. The CRCW25126K81FKEG (Vishay Dale) provides the same electrical performance with additional automotive AEC-Q200 qualification, suitable for applications requiring enhanced reliability documentation and automotive-grade screening.

Q: Are there packaging differences between these parts?

A: The Samsung RC6432F6811CS is supplied in bulk packaging. Both substitute parts (YAGEO and Vishay) are supplied in Tape & Reel (TR) format, which is standard for high-volume production environments and automated assembly processes.

Q: Do all three parts meet the same compliance standards?

A: Yes. All three parts are ROHS3 Compliant, REACH Unaffected, and carry Moisture Sensitivity Level 1 (Unlimited) ratings. Regulatory and environmental compliance is equivalent across all three options.

Q: What are the physical dimension tolerances for 2512 package substitution?

A: The 2512 (6432 Metric) package specification accommodates the dimensional variations observed across these three parts. Samsung dimensions are 6.30mm L x 3.20mm W, YAGEO is 6.35mm L x 3.10mm W, and Vishay is 6.30mm L x 3.15mm W. All fall within acceptable 2512 package tolerance bands for PCB footprint compatibility.

Q: Which substitute should be selected for new designs?

A: Selection depends on application requirements. For standard industrial applications, RC2512FK-076K81L (YAGEO) provides direct equivalence with superior stock availability. For automotive or high-reliability applications, CRCW25126K81FKEG (Vishay Dale) is recommended due to AEC-Q200 qualification.
