Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX1070 is determined by strict equivalence across the following critical parameters:

• Resistance value: 107 Ohms
• Tolerance: ±1%
• Power rating: 0.1W (1/10W)
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• Termination count: 2
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

All substitute parts listed meet these electrical and mechanical specifications. Automotive AEC-Q200 certification is present on the main part and most direct substitutes, providing additional qualification for automotive applications. Parts are grouped by direct equivalence (identical specifications) and similar equivalence (functionally compatible with minor feature variations).

Parameter Comparison

Engineering Selection Recommendations

For applications requiring AEC-Q200 automotive qualification, select from ERJ-3EKF1070V (Panasonic), CRCW0603107RFKEA (Vishay Dale), or RMCF0603FT107R (Stackpole Electronics). These parts maintain full automotive certification and are currently in active production status.

ERJ-3EKF1070V offers the highest inventory availability (57192 Pcs) among AEC-Q200 qualified alternatives. CRCW0603107RFKEA provides substantial inventory (25358 Pcs) with active product status. RMCF0603FT107R maintains AEC-Q200 compliance with lower inventory levels (769 Pcs).

MCR03ERTF1070 (Rohm Semiconductor) provides direct manufacturer continuity but is discontinued. RC0603FR-07107RL (YAGEO) offers active status and moisture-resistant composition but lacks AEC-Q200 certification.

All listed parts are ROHS3 compliant and MSL 1 rated, meeting environmental and handling requirements.

Frequently Asked Questions (FAQ)

Q: Can MCR03ERTF1070 replace MCR03EZPFX1070? A: Yes. Both are Rohm Semiconductor 107 Ohm ±1% 0.1W 0603 thick film resistors with identical electrical specifications and operating temperature range. The primary difference is packaging format (Cut Tape & Digi-Reel vs. original packaging). Both parts are discontinued.

Q: Which substitute is best for automotive applications? A: ERJ-3EKF1070V, CRCW0603107RFKEA, and RMCF0603FT107R all carry AEC-Q200 automotive qualification. Selection depends on availability and supply chain requirements. ERJ-3EKF1070V has the highest inventory.

Q: Is RC0603FR-07107RL compatible? A: RC0603FR-07107RL meets all electrical and mechanical specifications (107 Ω, ±1%, 0.1W, 0603 package, ±100ppm/°C, -55°C to 155°C). However, it lacks AEC-Q200 automotive certification and features moisture-resistant composition instead of standard thick film. Use only in non-automotive applications or where automotive qualification is not required.

Q: Are there dimensional differences between substitutes? A: Minor dimensional variations exist. MCR03EZPFX1070, ERJ-3EKF1070V, and RC0603FR-07107RL measure 0.063" L × 0.031" W (1.60mm × 0.80mm). CRCW0603107RFKEA measures 0.061" L × 0.033" W (1.55mm × 0.85mm). RMCF0603FT107R measures 0.061" L × 0.031" W (1.55mm × 0.80mm). All fit standard 0603 footprints. Height variations range from 0.020" to 0.022" (0.50mm to 0.55mm), all within 0603 specifications.

Q: What is the difference between "Direct" and "Similar" substitute classifications? A: Direct substitutes meet all specifications of the original part. Similar substitutes meet core electrical and mechanical requirements but may lack specific certifications (such as AEC-Q200) or have minor feature differences (such as moisture-resistant composition).
