Key Parameters

Substitute Part Grouping Explanation

Substitution for the MCR03EZPFX1912 is determined by strict equivalence across the following parameters: resistance value (19.1 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 two categories:

Direct Equivalents maintain full AEC-Q200 automotive qualification: CRCW060319K1FKEA (Vishay Dale), ERJ-3EKF1912V (Panasonic Electronic Components), and RMCF0603FT19K1 (Stackpole Electronics Inc).

Similar Equivalents meet all electrical and mechanical specifications but feature moisture-resistant construction instead of automotive AEC-Q200 rating: CR0603-FX-1912ELF (Bourns Inc.) and RC0603FR-0719K1L (YAGEO).

All substitute parts share identical resistance, tolerance, power rating, package dimensions, temperature coefficient, and operating temperature range. Dimensional variations are within manufacturing tolerances and do not affect PCB assembly compatibility.

Parameter Comparison

Engineering Selection Recommendations

For automotive applications requiring AEC-Q200 compliance, select from the direct equivalent group: CRCW060319K1FKEA, ERJ-3EKF1912V, or RMCF0603FT19K1. All three maintain full automotive qualification with active product status and high inventory availability.

For non-automotive applications or where moisture-resistant construction is preferred, CR0603-FX-1912ELF and RC0603FR-0719K1L are suitable alternatives. These parts meet all electrical specifications and RoHS compliance requirements but do not carry AEC-Q200 automotive certification.

All substitute parts are RoHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with identical HTSUS coding (8533.21.0030) to the original part.

Frequently Asked Questions (FAQ)

Q: Can I use CR0603-FX-1912ELF or RC0603FR-0719K1L as direct replacements in automotive applications?

A: These parts meet all electrical and mechanical specifications but lack AEC-Q200 automotive certification. Use only in non-automotive circuits or where automotive qualification is not required by design specifications.

Q: Are there dimensional differences between substitute parts?

A: Dimensional variations exist within manufacturing tolerances. The MCR03EZPFX1912, ERJ-3EKF1912V, and RC0603FR-0719K1L measure 0.063" L × 0.031" W (1.60mm × 0.80mm). The CRCW060319K1FKEA and RMCF0603FT19K1 measure 0.061" L × 0.031" W (1.55mm × 0.80mm). All are compatible with standard 0603 PCB footprints.

Q: What is the difference between direct equivalents and similar equivalents?

A: Direct equivalents (CRCW060319K1FKEA, ERJ-3EKF1912V, RMCF0603FT19K1) carry AEC-Q200 automotive certification. Similar equivalents (CR0603-FX-1912ELF, RC0603FR-0719K1L) feature moisture-resistant construction but lack automotive qualification.

Q: Are all substitute parts RoHS compliant?

A: All substitute parts are ROHS3 compliant and REACH unaffected, matching the original MCR03EZPFX1912 compliance status.

Q: Which substitute offers the highest inventory availability?

A: RC0603FR-0719K1L (YAGEO) has 279,980 pieces in stock, followed by ERJ-3EKF1912V (Panasonic) with 102,336 pieces and CRCW060319K1FKEA (Vishay Dale) with 80,106 pieces.
