KTR03EZPJ563 Equivalent & Substitute Parts

Part Overview

The KTR03EZPJ563 is a 56 kOhms ±5% thick film chip resistor manufactured by Rohm Semiconductor, rated for 0.1W (1/10W) power dissipation in a 0603 (1608 Metric) surface mount package. This component is AEC-Q200 automotive qualified and designed for high voltage applications across an operating temperature range of -55°C to 155°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are necessary when the primary part experiences supply constraints, lead time extensions, or when design requirements call for improved tolerance specifications or alternative packaging formats while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility for the KTR03EZPJ563 is determined by the following criteria:

Direct Equivalents (Same Electrical & Mechanical Specifications): Parts with identical resistance (56 kOhms), tolerance (±5%), power rating (0.1W), package (0603), composition (thick film), temperature coefficient (±200ppm/°C), and operating temperature range (-55°C to 155°C) are classified as direct equivalents. These parts maintain full functional interchangeability without design modification.

Upgrade Substitutes (Improved Tolerance): Parts with tighter tolerance specifications (±1% instead of ±5%) while maintaining all other electrical parameters are classified as upgrades. These provide enhanced precision for applications requiring stricter component tolerances. Temperature coefficient improves to ±100ppm/°C, reducing drift over temperature.

Similar Parts (Alternative Packaging or Feature Variations): Parts meeting all core electrical specifications but with minor dimensional variations or alternative packaging formats (Cut Tape vs. Tape & Reel) are classified as similar. These maintain electrical compatibility while offering supply or logistics flexibility.

Engineering Selection Recommendations

For AEC-Q200 Automotive Applications: When automotive qualification is mandatory, select from parts carrying AEC-Q200 certification: KTR03EZPF5602, CRCW060356K0JNEA, ERJ-3GEYJ563V, RMCF0603JT56K0, ERJ-3EKF5602V, or RMCF0603FT56K0. These maintain compliance with automotive reliability standards across the full operating temperature range.

For Tolerance-Critical Designs: Applications requiring tighter tolerance control should specify ±1% tolerance parts: KTR03EZPF5602, CRG0603F56K, ERJ-3EKF5602V, RC0603FR-0756KL, or RMCF0603FT56K0. These parts also provide improved temperature coefficient performance (±100ppm/°C vs. ±200ppm/°C).

For Standard Tolerance Applications: Direct equivalents maintaining ±5% tolerance and ±200ppm/°C temperature coefficient include CRCW060356K0JNEA, ERJ-3GEYJ563V, RMCF0603JT56K0, RC0603JR-0756KL, and CR0603-JW-563ELF. These are suitable for general-purpose circuit applications without precision requirements.

For Supply Chain Flexibility: YAGEO RC0603 series parts (RC0603FR-0756KL, RC0603JR-0756KL) and Panasonic ERJ-3GEYJ563V offer high inventory availability. Panasonic ERJ-3EKF5602V provides the largest stock position (309,921 units) for high-volume production requirements.

For Packaging Format Requirements: Cut Tape & Digi-Reel packaging is available from CRCW060356K0JNEA, RC0603FR-0756KL, RC0603JR-0756KL, and RMCF0603FT56K0 for automated assembly operations requiring alternative tape formats.

Frequently Asked Questions (FAQ)

Q: Can I substitute KTR03EZPJ563 with a ±1% tolerance part? A: Yes. Parts with ±1% tolerance (KTR03EZPF5602, ERJ-3EKF5602V, RMCF0603FT56K0, CRG0603F56K, RC0603FR-0756KL) are direct upgrades. They maintain identical resistance value, power rating, package, and operating temperature range while providing improved precision. Temperature coefficient also improves to ±100ppm/°C.

Q: Are all substitute parts AEC-Q200 qualified? A: No. AEC-Q200 certification is present on KTR03EZPJ563, KTR03EZPF5602, CRCW060356K0JNEA, ERJ-3GEYJ563V, RMCF0603JT56K0, ERJ-3EKF5602V, and RMCF0603FT56K0. Parts from TE Connectivity (CRG0603F56K), YAGEO (RC0603 series), and Bourns (CR0603-JW-563ELF) do not carry automotive qualification. Select AEC-Q200 parts only for automotive applications.

Q: What is the difference between Tape & Reel and Cut Tape & Digi-Reel packaging? A: Tape & Reel packaging supplies components on continuous carrier tape suitable for high-speed pick-and-place assembly. Cut Tape & Digi-Reel provides components on cut tape segments with reel backing, offering flexibility for lower-volume or mixed-component assembly operations. Electrical performance is identical; selection depends on assembly equipment compatibility.

Q: Can I use CR0603-JW-563ELF as a direct replacement? A: Yes, for non-automotive applications. CR0603-JW-563ELF matches all electrical specifications (56 kOhms, ±5%, 0.1W, 0603 package, ±200ppm/°C, -55°C to 155°C). However, it lacks AEC-Q200 certification, making it unsuitable for automotive designs requiring this qualification.

Q: Which substitute offers the best availability? A: Panasonic ERJ-3EKF5602V provides the highest inventory (309,921 units). For standard tolerance requirements, ERJ-3GEYJ563V offers 118,052 units. YAGEO RC0603FR-0756KL provides the largest overall stock (5,000,400 units) across all tolerance and packaging variants.

Q: Are all parts ROHS3 compliant? A: Yes. All listed parts carry ROHS3 compliance certification. All parts also maintain MSL 1 (Unlimited) moisture sensitivity rating and REACH Unaffected status, ensuring environmental and regulatory compliance across all substitute options.

Q: What is the temperature coefficient difference between ±5% and ±1% tolerance parts? A: Standard tolerance (±5%) parts maintain ±200ppm/°C temperature coefficient. Upgraded tolerance (±1%) parts improve to ±100ppm/°C, reducing resistance drift over the -55°C to 155°C operating range. This improvement is significant for precision analog circuits and temperature-sensitive applications.
