Substitute Part Grouping Explanation

Substitution eligibility for the RC6432J205CS is determined by strict adherence to the following criteria:

Primary Substitution Criteria (Mandatory Match):

• Resistance value: 2 MOhms (exact match required)
• Power rating: 1W (exact match required)
• Package / Case: 2512 (6432 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• RoHS Status: ROHS3 Compliant (minimum requirement)
• MSL Rating: 1 (Unlimited) (minimum requirement)

Secondary Substitution Criteria (Allowable Variation):

• Tolerance: ±5% or tighter (±1% is acceptable as upgrade)
• Moisture Resistance: Required feature (all substitutes must include)
• Packaging Format: Tape & Reel acceptable for manufacturing environments
• Manufacturer: Any qualified supplier meeting above criteria

Identified Substitute Parts:

1. RC2512FK-072ML (YAGEO) – Upgrade substitute with improved tolerance (±1% vs ±5%)
2. CRCW25122M00FKEG (Vishay Dale) – Equivalent substitute with automotive AEC-Q200 qualification

Both substitutes meet all mandatory criteria and maintain full electrical and mechanical compatibility with the RC6432J205CS.

Engineering Selection Recommendations

RC6432J205CS (Samsung Electro-Mechanics) – Primary Selection

Use the original Samsung part when:

• Existing design validation and qualification are complete
• Supply chain continuity with current manufacturer is prioritized
• Tolerance of ±5% meets circuit requirements
• Standard industrial applications without automotive requirements

RC2512FK-072ML (YAGEO) – Upgrade Substitute

Select this YAGEO equivalent when:

• Improved tolerance performance (±1%) is required for circuit optimization
• ROHS3 compliance and MSL 1 rating satisfy regulatory requirements
• Higher inventory availability (2967 units) supports production schedules
• Tape & Reel packaging is compatible with manufacturing processes

CRCW25122M00FKEG (Vishay Dale) – Automotive-Qualified Substitute

Specify this Vishay Dale part when:

• Automotive AEC-Q200 qualification is required for vehicle or industrial equipment applications
• Highest inventory availability (4036 units) is critical for supply assurance
• Tolerance upgrade to ±1% improves circuit performance
• ROHS3 and MSL 1 compliance meet all regulatory standards

All three parts are electrically and mechanically interchangeable within the specified parameters. Selection depends on application requirements, supply availability, and qualification status.

Frequently Asked Questions (FAQ)

Q1: Can RC2512FK-072ML replace RC6432J205CS directly on the PCB?

A: Yes. Both parts share identical 2512 (6432 Metric) package dimensions, footprint, and termination configuration. Physical and electrical substitution is direct. The ±1% tolerance of the YAGEO part is tighter than the ±5% specification of the Samsung part, making it a compatible upgrade.

Q2: What is the difference between ±5% and ±1% tolerance?

A: Tolerance defines the maximum deviation from the nominal 2 MOhm resistance value. The Samsung part (±5%) allows resistance between 1.9 and 2.1 MOhms. The YAGEO and Vishay parts (±1%) allow resistance between 1.98 and 2.02 MOhms. Tighter tolerance (±1%) provides greater accuracy for precision circuits but may not be necessary for all applications.

Q3: Is CRCW25122M00FKEG suitable for non-automotive applications?

A: Yes. AEC-Q200 automotive qualification is an additional feature that exceeds standard industrial requirements. The part meets all ROHS3, MSL 1, and environmental specifications required for general industrial use. It is a valid substitute for non-automotive applications.

Q4: What does MSL 1 (Unlimited) mean?

A: MSL (Moisture Sensitivity Level) 1 indicates the component has unlimited shelf life and requires no special moisture-control handling during storage or assembly. All three parts carry this rating, eliminating moisture-related procurement or storage constraints.

Q5: Are there packaging differences between these parts?

A: The Samsung part is specified with standard packaging. The YAGEO and Vishay parts are supplied in Tape & Reel (TR) format, which is standard for automated manufacturing environments. Tape & Reel packaging is compatible with pick-and-place equipment and does not affect electrical performance.

Q6: Can these parts be mixed in the same production batch?

A: Yes, provided the circuit design accepts the tolerance range of the loosest specification (±5%). If the design requires ±1% tolerance, only YAGEO RC2512FK-072ML or Vishay CRCW25122M00FKEG should be used. Mixing parts with different tolerances requires design verification.

Q7: Which part should be selected for maximum supply availability?

A: CRCW25122M00FKEG (Vishay Dale) offers the highest inventory at 4036 units, followed by RC2512FK-072ML (YAGEO) at 2967 units. For supply-critical applications, the Vishay part provides the best availability assurance.

Q8: Do all three parts meet REACH compliance?

A: Yes. All three parts are listed as REACH Unaffected, indicating full compliance with REACH (Registration, Evaluation, Authorization and Restriction of Chemicals) regulations.
