Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MCR03EZPFX1580 are classified into two categories based on feature alignment:

Direct Substitutes (Automotive AEC-Q200 Rated):

• CRCW0603158RFKEA (Vishay Dale)
• ERJ-3EKF1580V (Panasonic Electronic Components)
• RMCF0603FT158R (Stackpole Electronics Inc)

These parts match all critical parameters: 158 Ohms resistance, ±1% tolerance, 0.1W power rating, 0603 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range, and AEC-Q200 automotive qualification. All are ROHS3 compliant with MSL 1 rating.

Similar Substitutes (Moisture Resistant, Non-Automotive Rated):

• CR0603-FX-1580ELF (Bourns Inc.)
• RC0603FR-07158RL (YAGEO)

These parts share identical electrical specifications and package dimensions but feature moisture-resistant composition instead of automotive AEC-Q200 certification. Selection depends on application requirements regarding automotive qualification necessity.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring automotive AEC-Q200 compliance, select from direct substitutes: CRCW0603158RFKEA, ERJ-3EKF1580V, or RMCF0603FT158R. All three maintain full electrical and mechanical compatibility with the discontinued MCR03EZPFX1580 while offering active product status and established supply availability.

ERJ-3EKF1580V provides the highest inventory level (351,453 pieces), ensuring supply chain continuity for high-volume production. CRCW0603158RFKEA and RMCF0603FT158R offer intermediate inventory levels with comparable lead times.

For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-1580ELF and RC0603FR-07158RL are functionally equivalent. RC0603FR-07158RL offers the largest available inventory (202,226 pieces) among all alternatives.

All substitute parts are ROHS3 compliant with MSL 1 rating, matching the original component's environmental and regulatory status.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-1580ELF or RC0603FR-07158RL as direct replacements for MCR03EZPFX1580 in automotive circuits?

A: These parts are electrically and mechanically equivalent but lack AEC-Q200 automotive certification. Use only in non-automotive applications or where automotive qualification is not a design requirement.

Q: What are the physical dimension differences between substitute parts?

A: All parts conform to 0603 (1608 Metric) package standard. Minor variations exist in seated height (0.50mm to 0.55mm maximum) and length/width tolerances (1.55mm to 1.60mm length, 0.80mm to 0.85mm width), but these fall within standard PCB design tolerances and do not affect interchangeability.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes, all listed substitute parts are supplied in Tape & Reel (TR) format, matching the original component's packaging configuration for automated assembly compatibility.

Q: Do substitute parts maintain the same temperature coefficient performance?

A: All substitute parts specify ±100ppm/°C temperature coefficient with -55°C to 155°C operating range, identical to the MCR03EZPFX1580.

Q: Which substitute offers the best supply availability?

A: ERJ-3EKF1580V (Panasonic) provides the highest inventory at 351,453 pieces for AEC-Q200 applications. RC0603FR-07158RL (YAGEO) offers 202,226 pieces for non-automotive applications.
