Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the MCR03EZPFX2372 is determined by strict equivalence across the following parameters:

• Resistance value: 23.7 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
• Moisture sensitivity level: 1 (Unlimited)

Substitute parts are classified into two categories:

Direct Substitutes meet all electrical and mechanical parameters with AEC-Q200 automotive certification, ensuring full functional equivalence in automotive applications.

Similar Substitutes meet all core electrical and mechanical parameters but feature moisture-resistant construction instead of AEC-Q200 automotive rating. These are suitable for non-automotive applications or where moisture resistance is prioritized over automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

For Automotive Applications:

CRCW060323K7FKEA (Vishay Dale), ERJ-3EKF2372V (Panasonic), and RMCF0603FT23K7 (Stackpole) are direct substitutes with full AEC-Q200 automotive qualification. All three maintain identical electrical specifications and operating parameters. Selection among these three is based on packaging preference (Cut Tape & Digi-Reel for Vishay, Tape & Reel for Panasonic and Stackpole) and inventory availability.

For Non-Automotive Applications:

CR0603-FX-2372ELF (Bourns) and RC0603FR-0723K7L (YAGEO) are suitable alternatives where automotive qualification is not required. Both feature moisture-resistant construction and maintain all core electrical parameters. These parts are appropriate for consumer, industrial, or general-purpose applications.

Compliance Considerations:

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) rating, ensuring compatibility with standard manufacturing and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-2372ELF or RC0603FR-0723K7L in place of MCR03EZPFX2372 in automotive circuits?

A: CR0603-FX-2372ELF and RC0603FR-0723K7L lack AEC-Q200 automotive certification. Use these only in non-automotive applications. For automotive circuits, select from CRCW060323K7FKEA, ERJ-3EKF2372V, or RMCF0603FT23K7.

Q: Are there dimensional differences between the substitute parts?

A: Minor dimensional variations exist. MCR03EZPFX2372 and ERJ-3EKF2372V measure 0.063" L x 0.031" W (1.60mm x 0.80mm). CRCW060323K7FKEA measures 0.061" L x 0.033" W (1.55mm x 0.85mm). RMCF0603FT23K7 measures 0.061" L x 0.031" W (1.55mm x 0.80mm). All fit within 0603 package specifications and are PCB-compatible.

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

A: AEC-Q200 is an automotive qualification standard covering reliability under automotive environmental conditions. Moisture-resistant construction addresses humidity exposure. For automotive applications, AEC-Q200 certification is required. For general-purpose use, moisture-resistant parts are sufficient.

Q: Which substitute has the highest inventory availability?

A: RMCF0603FT23K7 (Stackpole) has 175,235 pieces in stock, followed by RC0603FR-0723K7L (YAGEO) with 123,495 pieces.

Q: Are all substitutes RoHS compliant?

A: Yes. All substitute parts are ROHS3 compliant with MSL 1 (Unlimited) rating, matching the original MCR03EZPFX2372 specifications.
