Substitute Part Grouping Explanation

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

Resistance value: 150 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
RoHS compliance: ROHS3 Compliant

Engineering Selection Recommendations

Primary Substitutes (Active Status, AEC-Q200 Certified):

KTR03EZPF1503 (Rohm Semiconductor) and CRCW0603150KFKEA (Vishay Dale) are the preferred direct substitutes. Both maintain active product status, full AEC-Q200 automotive certification, and identical electrical specifications. KTR03EZPF1503 is available in Tape & Reel packaging, while CRCW0603150KFKEA offers Cut Tape & Digi-Reel options.

Secondary Substitutes (Active Status, AEC-Q200 Certified):

ERJ-3EKF1503V (Panasonic), RMCF0603FG150K (Stackpole), and RMCF0603FT150K (Stackpole) provide active alternatives with full AEC-Q200 compliance. These parts are widely available with high inventory levels and support multiple packaging formats.

Alternative Substitutes (Active Status, Non-Automotive Certified):

CR0603-FX-1503ELF (Bourns), CRG0603F150K (TE Connectivity), and RC0603FR-07150KL (YAGEO) meet all electrical and mechanical parameters but lack AEC-Q200 automotive certification. These are suitable for non-automotive applications or where automotive qualification is not required.

Discontinued Parts (Not Recommended for New Designs):

CRCW0603150KFKEB (Vishay Dale) is discontinued at DiGi Electronics and should not be selected for new production designs.

Frequently Asked Questions (FAQ)

Q: Can MCR03EZPFX1503 be replaced with any of these substitutes in automotive applications?

A: For automotive applications requiring AEC-Q200 certification, use only KTR03EZPF1503, CRCW0603150KFKEA, ERJ-3EKF1503V, RMCF0603FG150K, or RMCF0603FT150K. CR0603-FX-1503ELF, CRG0603F150K, and RC0603FR-07150KL do not carry AEC-Q200 certification and are not qualified for automotive use.

Q: What is the difference between packaging types listed?

A: Tape & Reel (TR) packaging is standard for automated assembly lines. Cut Tape (CT) & Digi-Reel provides flexibility for lower-volume production. Bulk packaging is used for manual assembly or small quantities. All packaging types contain electrically identical components.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant and meet REACH requirements.

Q: Do all substitutes have the same moisture sensitivity level?

A: Yes. All parts listed have MSL 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Can I use CR0603-FX-1503ELF or RC0603FR-07150KL in place of MCR03EZPFX1503?

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 requirement.

Q: Which substitute has the highest inventory availability?

A: CRCW0603150KFKEA (Vishay Dale) has the highest inventory at 149,633 pieces. RMCF0603FT150K (Stackpole) follows with 297,631 pieces in Tape & Reel format.
