Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX1103 is determined by strict equivalence across the following parameters: resistance value (110 kOhms), tolerance (±1%), power rating (0.1W), package type (0603), composition (thick film), temperature coefficient (±100ppm/°C), operating temperature range (-55°C to 155°C), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

Substitute parts are grouped into three categories:

Direct Equivalents maintain all electrical and mechanical specifications with identical or compatible packaging formats. These parts are interchangeable without design modification.

Upgrade Parts meet or exceed all base specifications while offering enhanced features such as automotive AEC-Q200 certification combined with high voltage capability, or improved product status (Active vs. Discontinued).

Similar Parts satisfy all core electrical parameters and package requirements but may feature additional material properties such as anti-sulfur treatment or moisture resistance that provide enhanced environmental protection without altering core functionality.

Parameter Comparison

Engineering Selection Recommendations

For Automotive AEC-Q200 Applications: Select KTR03EZPF1103 (Rohm Semiconductor, Active status), CRCW0603110KFKEA (Vishay Dale, Active status), ERJ-3EKF1103V (Panasonic, Active status), RMCF0603FT110K (Stackpole, Active status), or ERJ-S03F1103V (Panasonic with anti-sulfur treatment, Active status). All maintain AEC-Q200 certification with current product availability.

For General Industrial Applications: CR0603-FX-1103ELF (Bourns, moisture resistant) or RC0603FR-07110KL (YAGEO, moisture resistant) provide equivalent electrical performance with enhanced environmental protection and active product status.

For Rohm Semiconductor Continuity: KTR03EZPF1103 is the recommended upgrade path from MCR03EZPFX1103, offering active product status, AEC-Q200 certification, and high voltage capability within the same manufacturer ecosystem.

All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and MSL 1 (Unlimited) moisture sensitivity rating, ensuring regulatory and supply chain compatibility.

Frequently Asked Questions (FAQ)

Q: Can MCR03ERTF1103 directly replace MCR03EZPFX1103?

A: MCR03ERTF1103 is a direct electrical equivalent with identical resistance, tolerance, power rating, package, and temperature specifications. However, it lacks AEC-Q200 automotive certification. Use only in non-automotive applications or where automotive qualification is not required.

Q: What is the difference between KTR03EZPF1103 and MCR03EZPFX1103?

A: Both are Rohm Semiconductor 110 kOhms ±1% 0603 resistors with AEC-Q200 certification. KTR03EZPF1103 adds high voltage capability and maintains Active product status, making it the preferred upgrade path. Electrical performance is equivalent.

Q: Are Vishay Dale CRCW0603110KFKEA and CRCW0603110KFKEB interchangeable?

A: Both parts are electrically and mechanically identical with AEC-Q200 certification. CRCW0603110KFKEA is Active status with higher inventory availability. CRCW0603110KFKEB is Discontinued at DiGi Electronics. Select CRCW0603110KFKEA for new designs.

Q: What is the advantage of ERJ-S03F1103V over ERJ-3EKF1103V?

A: ERJ-S03F1103V includes anti-sulfur treatment in addition to standard AEC-Q200 automotive certification. Both maintain identical electrical specifications. Select ERJ-S03F1103V for applications requiring enhanced sulfur resistance in harsh environments.

Q: Can I use CR0603-FX-1103ELF or RC0603FR-07110KL in automotive applications?

A: CR0603-FX-1103ELF and RC0603FR-07110KL lack AEC-Q200 automotive certification. Use only in non-automotive or general industrial applications. For automotive requirements, select from AEC-Q200 certified alternatives.

Q: Are there dimensional differences between substitute parts?

A: All parts conform to 0603 (1608 Metric) package specification. Minor dimensional variations exist within tolerance: length ranges 0.061" to 0.063" (1.55mm to 1.60mm), width ranges 0.031" to 0.033" (0.80mm to 0.85mm), height ranges 0.020" to 0.022" (0.50mm to 0.55mm). These variations are within standard PCB design tolerances and do not affect interchangeability.

Q: Which substitute offers the best inventory availability?

A: RC0603FR-07110KL (YAGEO) offers the highest inventory at 207,069 pieces. RMCF0603FT110K (Stackpole) provides 170,174 pieces. Both are Active status with immediate availability for high-volume requirements.
