Substitute Part Grouping Explanation

Substitute parts for the MCR03EZPFX9760 are qualified based on strict equivalence across the following parameters:

Resistance value: 976 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
RoHS3 compliance
MSL 1 rating

All substitute parts listed maintain these core electrical and mechanical specifications. Variations in physical dimensions (length, width, height) within standard tolerances and differences in packaging format (Cut Tape, Digi-Reel, Tape & Reel) do not affect functional equivalence. Feature differences (Automotive AEC-Q200 vs. Anti-Sulfur vs. Moisture Resistant) represent different design approaches to reliability but do not alter the core electrical performance required for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can I directly replace MCR03EZPFX9760 with any of the listed substitute parts?

A: Yes. All listed substitute parts meet identical electrical specifications (976 Ohms ±1%, 0.1W, 0603 package, ±100ppm/°C temperature coefficient, -55°C to 155°C operating range) and are functionally equivalent for direct PCB substitution without circuit redesign.

Q: What is the difference between AEC-Q200 rated parts and moisture-resistant parts?

A: AEC-Q200 rated parts (CRCW0603976RFKEA, ERJ-3EKF9760V, RMCF0603FT976R) meet automotive industry reliability standards. Moisture-resistant parts (CR0603-FX-9760ELF, RC0603FR-07976RL) employ design approaches to resist moisture ingress. Both achieve ROHS3 compliance and MSL 1 rating. Selection depends on application requirements.

Q: Are there physical dimension differences between substitute parts?

A: Minor variations exist within standard tolerances. Length ranges from 0.061" to 0.063" (1.55mm to 1.60mm), width from 0.031" to 0.033" (0.80mm to 0.85mm), and height from 0.020" to 0.022" (0.50mm to 0.55mm). These variations are within standard 0603 package tolerances and do not affect PCB layout or assembly compatibility.

Q: Which substitute part should I choose for new designs?

A: For automotive applications, select from CRCW0603976RFKEA, ERJ-3EKF9760V, or RMCF0603FT976R based on availability and packaging preference. For general industrial applications, RC0603FR-07976RL offers high inventory availability. All are in active production status.

Q: What packaging formats are available?

A: Substitute parts are available in Cut Tape (CT) & Digi-Reel format (CRCW0603976RFKEA, TRR03EZPF9760) and Tape & Reel (TR) format (ERJ-3EKF9760V, RMCF0603FT976R, CR0603-FX-9760ELF, RC0603FR-07976RL). Select based on assembly equipment and procurement requirements.
