MCR03EZPFX1870 Equivalent & Substitute Parts

Part Overview

The MCR03EZPFX1870 is a 187 Ohms ±1% 0.1W chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This thick film automotive-grade component meets AEC-Q200 qualification standards for automotive applications. The part is currently discontinued at DiGi Electronics, making equivalent substitutes necessary for ongoing production and maintenance requirements. Direct electrical and mechanical equivalents are available from multiple manufacturers with identical or compatible specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX1870 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 187 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.1W / 1/10W (exact match required)
• Package Type: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±100ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• RoHS Compliance: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: MSL 1 (exact match required)

All substitute parts listed below meet these criteria. The CRCW0603187RFKEA, ERJ-3EKF1870V, and RMCF0603FT187R are direct equivalents with full AEC-Q200 automotive qualification. The RC0603FR-07187RL is classified as a similar substitute due to moisture-resistant features rather than full automotive AEC-Q200 certification, though it maintains all core electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (AEC-Q200 Qualified):

CRCW0603187RFKEA, ERJ-3EKF1870V, and RMCF0603FT187R are direct functional and mechanical equivalents with full AEC-Q200 automotive qualification. All three maintain identical electrical specifications and operating parameters. Selection among these three should be based on availability, lead time, and packaging requirements. All are supplied in Tape & Reel format and are currently in active production status.

Alternative Substitute (Non-Automotive Rated):

RC0603FR-07187RL from YAGEO meets all core electrical and mechanical specifications but lacks explicit AEC-Q200 automotive certification. This part features moisture-resistant construction and maintains the same resistance, tolerance, power rating, package, and temperature characteristics. Use of this substitute should be limited to non-automotive applications or where automotive qualification is not a design requirement.

Frequently Asked Questions (FAQ)

Q: Can I use RC0603FR-07187RL as a direct replacement for MCR03EZPFX1870 in automotive applications?

A: RC0603FR-07187RL is not recommended for automotive applications requiring AEC-Q200 qualification. While it meets all electrical and mechanical specifications, it lacks explicit automotive certification. Use CRCW0603187RFKEA, ERJ-3EKF1870V, or RMCF0603FT187R for automotive designs.

Q: Are all substitute parts available in the same packaging format?

A: All active substitute parts (CRCW0603187RFKEA, ERJ-3EKF1870V, RMCF0603FT187R, and RC0603FR-07187RL) are supplied in Tape & Reel (TR) packaging, suitable for automated assembly processes.

Q: What is the physical size difference between the MCR03EZPFX1870 and its substitutes?

A: The MCR03EZPFX1870 measures 0.063" L x 0.031" W (1.60mm x 0.80mm) with a maximum seated height of 0.022" (0.55mm). CRCW0603187RFKEA measures 0.061" L x 0.033" W (1.55mm x 0.85mm) with 0.020" (0.50mm) height. RMCF0603FT187R measures 0.061" L x 0.031" W (1.55mm x 0.80mm) with 0.022" (0.55mm) height. ERJ-3EKF1870V and RC0603FR-07187RL match the original dimensions exactly. These minor dimensional variations are within standard 0603 package tolerances and do not affect PCB layout compatibility.

Q: Do all substitute parts meet RoHS and REACH compliance requirements?

A: All substitute parts listed are ROHS3 compliant and REACH unaffected, matching the compliance status of the original MCR03EZPFX1870.

Q: What is the moisture sensitivity level for these resistors?

A: All parts, including substitutes, carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
