Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX3402 is determined by strict equivalence across the following critical parameters:

• Resistance value: 34 kOhms
• Tolerance: ±1%
• Power rating: 0.1W
• Package: 0603 (1608 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C to 155°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Substitute parts are categorized as Direct Manufacturer equivalents (CRCW060334K0FKEA, ERJ-3EKF3402V, RMCF0603FT34K0) when all parameters match exactly and AEC-Q200 automotive rating is maintained. Similar parts (AC0603FR-0734KL, CR0603-FX-3402ELF, RC0603FR-0734KL) meet all electrical and mechanical specifications but may have variations in specific feature sets such as moisture resistance designation.

Parameter Comparison

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 compliance, CRCW060334K0FKEA (Vishay Dale), ERJ-3EKF3402V (Panasonic Electronic Components), and RMCF0603FT34K0 (Stackpole Electronics Inc) are direct equivalents with active product status and full automotive certification. These three parts maintain identical electrical specifications, package dimensions, and compliance ratings.

AC0603FR-0734KL and RC0603FR-0734KL from YAGEO are functionally equivalent with AEC-Q200 rating and active status. CR0603-FX-3402ELF from Bourns Inc. meets all electrical and mechanical specifications but lacks explicit AEC-Q200 automotive certification in the provided data.

Selection should prioritize parts with active product status and confirmed AEC-Q200 rating for automotive circuit applications. All candidates maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard manufacturing processes.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-3402ELF as a direct replacement for MCR03EZPFX3402 in automotive applications?

A: CR0603-FX-3402ELF meets all electrical and mechanical specifications (34 kOhms ±1%, 0.1W, 0603 package, ±100ppm/°C, -55°C to 155°C). However, the provided data does not confirm AEC-Q200 automotive certification for this part. For automotive circuits requiring AEC-Q200 compliance, CRCW060334K0FKEA, ERJ-3EKF3402V, or RMCF0603FT34K0 are preferred.

Q: What is the difference between Direct Manufacturer equivalents and Similar parts?

A: Direct Manufacturer equivalents (CRCW060334K0FKEA, ERJ-3EKF3402V, RMCF0603FT34K0) maintain identical specifications including AEC-Q200 automotive rating. Similar parts (AC0603FR-0734KL, CR0603-FX-3402ELF, RC0603FR-0734KL) meet all core electrical and mechanical parameters but may have variations in feature designations or certifications.

Q: Are there physical dimension differences between substitute parts?

A: All substitute parts use the 0603 (1608 Metric) package. Minor variations exist in seated height and length/width dimensions within the 0603 standard tolerance range (e.g., 1.55mm to 1.60mm length, 0.80mm to 0.85mm width, 0.50mm to 0.55mm height). These variations are within standard PCB design tolerances and do not affect circuit functionality.

Q: Which substitute part has the highest inventory availability?

A: RC0603FR-0734KL from YAGEO has 388,353 pieces in stock, followed by RMCF0603FT34K0 from Stackpole with 191,717 pieces. ERJ-3EKF3402V from Panasonic has 121,291 pieces available.

Q: Do all substitute parts have the same moisture sensitivity level?

A: Yes. All substitute parts maintain MSL 1 (Unlimited) rating, identical to the original MCR03EZPFX3402, ensuring compatibility with standard storage and handling procedures.
