Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX2551 is determined by strict equivalence across the following parameters:

• Resistance value: 2.55 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 Equivalents meet all electrical and mechanical parameters with automotive AEC-Q200 certification, ensuring full functional interchangeability in automotive applications.

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

Parameter Comparison

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 certification, select from the direct equivalent group: CRCW06032K55FKEA (Vishay Dale), ERJ-3EKF2551V (Panasonic Electronic Components), or RMCF0603FT2K55 (Stackpole Electronics Inc). All three maintain full compliance with automotive qualification standards and are currently in active production with substantial inventory availability.

For non-automotive applications or where moisture resistance is the primary design consideration, CR0603-FX-2551ELF (Bourns Inc.) and RC0603FR-072K55L (YAGEO) provide equivalent electrical performance with moisture-resistant construction. RC0603FR-072K55L offers the highest inventory availability among all substitutes.

All substitute parts maintain ROHS3 compliance, MSL rating of 1 (Unlimited), and identical electrical specifications to the original MCR03EZPFX2551.

Frequently Asked Questions (FAQ)

Q: Can I use a moisture-resistant substitute in an automotive application? A: Moisture-resistant parts (CR0603-FX-2551ELF, RC0603FR-072K55L) lack AEC-Q200 automotive certification. Use direct equivalents with AEC-Q200 rating for automotive applications.

Q: Are all substitutes mechanically compatible with the original part? A: Yes. All substitutes use the 0603 (1608 Metric) package with identical termination count (2) and compatible physical dimensions. Dimensional variations are within standard manufacturing tolerances.

Q: What is the difference between direct and similar equivalents? A: Direct equivalents carry AEC-Q200 automotive certification; similar equivalents feature moisture-resistant construction without automotive qualification. Selection depends on application requirements.

Q: Can I mix different substitute manufacturers in the same assembly? A: Yes. All substitutes meet identical electrical and mechanical specifications. Mixed sourcing is permissible from a functional standpoint.

Q: Which substitute has the best availability? A: RC0603FR-072K55L (YAGEO) has the highest inventory at 963,270 pieces. For automotive-qualified parts, RMCF0603FT2K55 (Stackpole Electronics Inc) offers 182,638 pieces.
