KTR03EZPJ754 Equivalent & Substitute Parts

Part Overview

The KTR03EZPJ754 is a 750 kOhms ±5% thick film chip resistor in 0603 (1608 Metric) package rated for 0.1W power dissipation. Manufactured by Rohm Semiconductor, this component meets Automotive AEC-Q200 specifications and operates across -55°C to 155°C. The part is currently active in production with 1056 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when design requirements shift toward higher tolerance specifications, or when alternative packaging formats are required for manufacturing optimization.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Direct Equivalents (Same Tolerance ±5%): Parts maintaining identical resistance value, tolerance, power rating, package format, and operating temperature range. These parts are interchangeable without circuit redesign.

Upgrade Substitutes (Tighter Tolerance ±1%): Parts with improved tolerance specification while maintaining all other electrical and mechanical parameters. These provide enhanced accuracy and may be used when circuit performance benefits from reduced tolerance stack-up.

Packaging Variants: Parts with identical electrical specifications but different delivery formats (Tape & Reel versus Cut Tape & Digi-Reel) for manufacturing flexibility.

Manufacturer Variants: Parts from different manufacturers meeting the same electrical and mechanical specifications, enabling supply chain diversification.

Engineering Selection Recommendations

For Direct Replacement (Same Specifications): CRCW0603750KJNEA, ERJ-3GEYJ754V, and RMCF0603JT750K provide equivalent performance with identical tolerance and temperature coefficient specifications. All three maintain AEC-Q200 automotive qualification and ROHS3 compliance. CRCW0603750KJNEA offers the highest inventory availability at 15,695 units, while ERJ-3GEYJ754V provides 75,841 units in stock.

For Improved Tolerance Requirements: KTR03EZPF7503, ERJ-3EKF7503V, and RMCF0603FT750K upgrade to ±1% tolerance with reduced temperature coefficient (±100ppm/°C). All maintain AEC-Q200 qualification and Tape & Reel packaging. RMCF0603FT750K has the largest inventory at 259,100 units.

For Non-Automotive Applications: RC0603FR-07750KL and RC0603JR-07750KL from YAGEO provide moisture-resistant thick film construction without AEC-Q200 rating. These are suitable for commercial-grade applications where automotive qualification is not required.

Avoid: MCR03ERTF7503 is discontinued at DiGi Electronics and should not be selected for new designs despite active inventory status.

Frequently Asked Questions (FAQ)

Q: Can I substitute KTR03EZPJ754 with a ±1% tolerance part? A: Yes. KTR03EZPF7503, ERJ-3EKF7503V, and RMCF0603FT750K are direct electrical and mechanical substitutes with improved tolerance. The tighter tolerance does not create incompatibility; it provides enhanced accuracy.

Q: Are all substitute parts AEC-Q200 qualified? A: No. CRCW0603750KJNEA, ERJ-3GEYJ754V, RMCF0603JT750K, KTR03EZPF7503, ERJ-3EKF7503V, and RMCF0603FT750K carry AEC-Q200 qualification. RC0603FR-07750KL, RC0603JR-07750KL, and CR0603-JW-754ELF do not. Select AEC-Q200 parts for automotive applications.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging? A: Both formats contain identical components. Tape & Reel is continuous reel packaging for high-volume automated assembly. Cut Tape & Digi-Reel provides smaller quantities on cut tape segments. Electrical and mechanical performance is identical.

Q: Can I use CR0603-JW-754ELF as a substitute? A: CR0603-JW-754ELF matches all electrical and mechanical specifications but lacks AEC-Q200 automotive qualification. Use only in non-automotive applications where automotive certification is not required.

Q: Why does MCR03ERTF7503 show inventory but is marked discontinued? A: MCR03ERTF7503 is discontinued at DiGi Electronics but existing stock remains available. For new designs, select active parts: KTR03EZPF7503, ERJ-3EKF7503V, or RMCF0603FT750K.

Q: Which substitute has the best inventory availability? A: RC0603FR-07750KL has 406,668 units in stock. For AEC-Q200 qualified parts, RMCF0603FT750K provides 259,100 units.
