Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RC6432F2491CS are qualified based on strict equivalence of the following parameters:

Electrical Equivalence Requirements:

• Resistance value: 2.49 kOhms (exact match)
• Tolerance: ±1% (exact match)
• Power rating: 1W (exact match)
• Temperature coefficient: ±100ppm/°C (exact match)
• Operating temperature range: -55°C ~ 155°C (exact match)

Mechanical Compatibility Requirements:

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

Compliance Requirements:

• RoHS3 Compliant (maintained across all substitutes)
• Moisture Sensitivity Level 1 (Unlimited) (maintained across all substitutes)
• REACH Unaffected status (maintained across all substitutes)

All three substitute parts meet these criteria. Dimensional variations within the 2512 package specification (length 6.30-6.35mm, width 3.10-3.20mm, height 0.65-0.70mm) remain within standard PCB assembly tolerances and do not affect functional substitution.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are functionally equivalent to the RC6432F2491CS and maintain Active product status with full RoHS3 and REACH compliance. Selection among these options is determined by application-specific requirements and supply availability:

RC2512FK-072K49L (YAGEO): Direct functional equivalent with moisture-resistant thick film construction. Highest inventory availability at 4983 units. Supplied in Tape & Reel packaging. Suitable for standard industrial and commercial applications.

CRCW25122K49FKEG (Vishay Dale): Includes AEC-Q200 automotive qualification rating. Largest inventory at 25458 units. Recommended for automotive applications or systems requiring automotive-grade component certification. Supplied in Tape & Reel packaging.

RMCF2512FT2K49 (Stackpole Electronics Inc): Includes AEC-Q200 automotive qualification rating. Inventory of 12405 units. Recommended for automotive applications or systems requiring automotive-grade component certification. Supplied in Tape & Reel packaging.

For non-automotive applications, RC2512FK-072K49L provides equivalent performance. For automotive or mission-critical applications, CRCW25122K49FKEG or RMCF2512FT2K49 are appropriate selections based on AEC-Q200 compliance.

Frequently Asked Questions (FAQ)

Q: Can RC2512FK-072K49L be used as a direct replacement for RC6432F2491CS?

A: Yes. Both parts share identical electrical specifications (2.49 kOhms, ±1%, 1W, ±100ppm/°C, -55°C to 155°C), identical package format (2512), and equivalent environmental ratings (MSL 1, RoHS3 Compliant, REACH Unaffected). Mechanical dimensions remain within standard PCB assembly tolerances.

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

A: The primary difference is AEC-Q200 automotive qualification. CRCW25122K49FKEG and RMCF2512FT2K49 carry AEC-Q200 ratings, making them suitable for automotive applications. RC2512FK-072K49L does not carry this rating. All other electrical and mechanical parameters are identical.

Q: Are dimensional variations between substitutes significant?

A: Dimensional variations (length 6.30-6.35mm, width 3.10-3.20mm, height 0.65-0.70mm) fall within the 2512 package specification and standard PCB assembly tolerances. These variations do not affect functional performance or PCB layout compatibility.

Q: Can substitutes be mixed in the same assembly?

A: Yes. All substitutes meet identical electrical specifications and package standards. Mixed usage within a single assembly does not create functional or reliability issues.

Q: Which substitute has the best supply availability?

A: CRCW25122K49FKEG (Vishay Dale) has the highest inventory at 25458 units, followed by RMCF2512FT2K49 (Stackpole) at 12405 units, and RC2512FK-072K49L (YAGEO) at 4983 units.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All four parts (main part and three substitutes) are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.
