Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX2493 is determined by strict equivalence across the following electrical and mechanical parameters:

• Resistance value: 249 kOhms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Substitute parts are classified into two categories:

Direct Substitutes maintain full AEC-Q200 automotive qualification and identical electrical specifications. These parts are pin-compatible and functionally equivalent for automotive applications.

Similar Substitutes meet all electrical and mechanical parameters but feature moisture-resistant construction instead of AEC-Q200 automotive rating. These are suitable for non-automotive applications or where moisture resistance is prioritized over automotive certification.

Parameter Comparison

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 compliance, select from the direct substitutes with active product status:

• ERJ-3EKF2493V (Panasonic) offers the highest inventory availability (122,319 pcs) and active product status with Cut Tape & Digi-Reel packaging.
• RMCF0603FT249K (Stackpole Electronics) provides active status with substantial inventory (169,969 pcs) and Tape & Reel packaging.
• CRCW0603249KFKEA (Vishay Dale) is available in active status (85,772 pcs) with Cut Tape & Digi-Reel packaging.

For non-automotive applications where AEC-Q200 certification is not required, similar substitutes with moisture-resistant construction are available:

• RC0603FR-07249KL (YAGEO) offers the largest inventory (203,236 pcs) with active status.
• CR0603-FX-2493ELF (Bourns) provides active status with 51,640 pcs in stock.

All substitute parts maintain ROHS3 compliance, MSL rating of 1 (Unlimited), and identical electrical specifications to the original MCR03EZPFX2493.

Frequently Asked Questions (FAQ)

Q: Can I use a moisture-resistant substitute in place of an AEC-Q200 rated part?

A: No. Moisture-resistant parts (CR0603-FX-2493ELF, RC0603FR-07249KL) lack AEC-Q200 automotive certification. Use these only in non-automotive applications. For automotive use, select from direct substitutes with AEC-Q200 rating.

Q: Are all substitute parts pin-compatible with the MCR03EZPFX2493?

A: Yes. All listed substitutes use the 0603 (1608 Metric) package with 2 terminations, ensuring mechanical and electrical compatibility in PCB layouts designed for the original part.

Q: What is the difference between Cut Tape & Digi-Reel and Tape & Reel packaging?

A: Both are reel-based packaging formats suitable for automated assembly. Cut Tape & Digi-Reel offers flexibility for smaller quantities, while Tape & Reel is optimized for high-volume production runs. Selection depends on manufacturing volume requirements.

Q: Do all substitutes have the same temperature coefficient?

A: Yes. All substitute parts maintain ±100ppm/°C temperature coefficient and -55°C to 155°C operating range, matching the original MCR03EZPFX2493 specifications.

Q: Which substitute has the best availability?

A: RMCF0603FT249K (Stackpole Electronics) has the highest inventory at 169,969 pcs with active product status and AEC-Q200 compliance.
