Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict equivalence across the following parameters: resistance value (140 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, MSL 1).

Substitute parts are categorized as follows:

Upgrade Substitute: KTR03EZPF1403 (Rohm Semiconductor) — Same manufacturer, active product status, identical electrical specifications with additional high-voltage feature designation.

Direct Substitutes: CRCW0603140KFKEA (Vishay Dale), ERJ-3EKF1403V (Panasonic Electronic Components), RMCF0603FT140K (Stackpole Electronics Inc) — All meet core electrical and mechanical parameters with active product status.

Similar Substitutes: CR0603-FX-1403ELF (Bourns Inc.), RC0603FR-07140KL (YAGEO) — Meet all electrical and mechanical parameters; feature designation differs (moisture resistant vs. automotive AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

For applications requiring strict automotive compliance, select from direct substitutes with active AEC-Q200 certification: KTR03EZPF1403 (Rohm Semiconductor), CRCW0603140KFKEA (Vishay Dale), ERJ-3EKF1403V (Panasonic Electronic Components), or RMCF0603FT140K (Stackpole Electronics Inc). All maintain identical electrical specifications and operating parameters.

KTR03EZPF1403 offers the advantage of same-manufacturer sourcing with higher inventory availability (5701 units) and active product status.

For non-automotive applications where AEC-Q200 certification is not required, CR0603-FX-1403ELF (Bourns Inc.) and RC0603FR-07140KL (YAGEO) provide equivalent electrical performance with moisture-resistant construction and superior inventory levels.

All substitutes maintain ROHS3 compliance, MSL 1 rating, and identical thermal characteristics.

Frequently Asked Questions (FAQ)

Q: Can MCR03EZPFX1403 be replaced with KTR03EZPF1403? A: Yes. Both are Rohm Semiconductor products with identical electrical specifications (140 kOhms ±1%, 0.1W, 0603 package, ±100ppm/°C, -55°C to 155°C). KTR03EZPF1403 is the active equivalent with higher inventory availability.

Q: Are all substitute parts AEC-Q200 certified? A: Direct substitutes (KTR03EZPF1403, CRCW0603140KFKEA, ERJ-3EKF1403V, RMCF0603FT140K) carry AEC-Q200 certification. Similar substitutes (CR0603-FX-1403ELF, RC0603FR-07140KL) do not carry this automotive rating but meet all electrical and mechanical parameters.

Q: Do package dimensions vary between substitutes? A: All substitutes use 0603 (1608 Metric) package. Minor dimensional variations exist: MCR03EZPFX1403, ERJ-3EKF1403V, and RC0603FR-07140KL measure 0.063" L × 0.031" W; CRCW0603140KFKEA and RMCF0603FT140K measure 0.061" L × 0.031" W. Height differences range from 0.020" to 0.022" maximum seated height. These variations remain within standard 0603 package tolerances and do not affect PCB layout compatibility.

Q: What is the difference between direct and similar substitutes? A: Direct substitutes maintain AEC-Q200 automotive certification identical to the original part. Similar substitutes meet all electrical and mechanical specifications but feature moisture-resistant construction instead of automotive-grade designation. Selection depends on application requirements.

Q: Are all substitutes ROHS3 compliant? A: Yes. All listed substitutes maintain ROHS3 compliance and MSL 1 (unlimited moisture sensitivity level) rating.
