KTR03EZPJ244 Equivalent & Substitute Parts

Part Overview

The KTR03EZPJ244 is a 240 kOhms ±5% thick film chip resistor manufactured by Rohm Semiconductor in 0603 (1608 Metric) package format. This component is rated for 0.1W (1/10W) power dissipation and meets automotive AEC-Q200 qualification standards with high voltage capability. The part is active in production status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1).

Equivalent and substitute parts are necessary when the primary part experiences supply constraints, inventory limitations, or when design requirements permit tolerance or feature upgrades within the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KTR03EZPJ244 is determined by strict equivalence in the following parameters:

• Resistance value: 240 kOhms (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Package format: 0603 (1608 Metric) (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)
• Composition: Thick Film (exact match required)
• Number of terminations: 2 (exact match required)

Tolerance (±5% or ±1%), temperature coefficient (±200ppm/°C or ±100ppm/°C), and specific feature sets (Automotive AEC-Q200, Moisture Resistant) may vary between substitute parts while maintaining functional equivalence. Parts are categorized as direct substitutes (matching tolerance and features), upgrade substitutes (improved tolerance or temperature coefficient), or similar substitutes (alternative manufacturers with equivalent electrical performance).

Parameter Comparison

Engineering Selection Recommendations

All listed substitute parts maintain electrical and mechanical compatibility with the KTR03EZPJ244 across core parameters: 240 kOhms resistance, 0.1W power rating, 0603 package, and -55°C to 155°C operating range.

Direct substitutes matching ±5% tolerance and ±200ppm/°C temperature coefficient are CRCW0603240KJNEA (Vishay Dale), ERJ-3GEYJ244V (Panasonic), RMCF0603JT240K (Stackpole), and CR0603-JW-244ELF (Bourns). These parts are functionally equivalent for applications where the original specification tolerance is acceptable.

Upgrade substitutes with improved ±1% tolerance and ±100ppm/°C temperature coefficient include KTR03EZPF2403 (Rohm Semiconductor), ERJ-3EKF2403V (Panasonic), RC0603FR-07240KL (YAGEO), and RMCF0603FT240K (Stackpole). These parts provide tighter tolerance performance while maintaining all other electrical characteristics.

RC0603JR-07240KL (YAGEO) offers ±5% tolerance with ±100ppm/°C temperature coefficient and moisture-resistant features, suitable for applications requiring enhanced environmental protection without tolerance upgrade.

All parts carry ROHS3 compliance and MSL 1 rating. Parts designated with Automotive AEC-Q200 (Rohm, Vishay, Panasonic, Stackpole) maintain automotive qualification. Parts from YAGEO and Bourns feature moisture-resistant composition as an alternative to high-voltage thick film construction.

Frequently Asked Questions (FAQ)

Q: Can KTR03EZPJ244 be replaced with a ±1% tolerance part?

A: Yes. Parts with ±1% tolerance (KTR03EZPF2403, ERJ-3EKF2403V, RC0603FR-07240KL, RMCF0603FT240K) are direct electrical upgrades. They maintain the same 240 kOhms resistance, 0.1W power rating, 0603 package, and operating temperature range. The tighter tolerance provides improved circuit accuracy.

Q: What is the difference between Automotive AEC-Q200 and Moisture Resistant variants?

A: Automotive AEC-Q200 parts (Rohm, Vishay, Panasonic, Stackpole) are qualified for automotive applications with high-voltage thick film construction. Moisture-resistant parts (YAGEO, Bourns) feature alternative composition for enhanced environmental protection. Both meet ROHS3 compliance and MSL 1 requirements. Selection depends on application environment and qualification requirements.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All listed substitutes use 0603 (1608 Metric) package with 2 terminations. Physical dimensions are equivalent within manufacturing tolerances (0.063" L x 0.031" W nominal, height 0.022" maximum). Packaging format (Tape & Reel or Cut Tape) may vary by supplier but does not affect component compatibility.

Q: Which substitute has the highest inventory availability?

A: ERJ-3GEYJ244V (Panasonic) has 1,056,114 pieces in stock, followed by RC0603FR-07240KL (YAGEO) with 253,255 pieces. Both are direct substitutes or upgrades with full electrical compatibility.

Q: Can temperature coefficient differences affect circuit performance?

A: Temperature coefficient differences (±200ppm/°C vs. ±100ppm/°C) affect resistance stability across temperature extremes. Parts with ±100ppm/°C provide superior stability in applications with wide temperature operation or stringent accuracy requirements. For circuits operating within narrow temperature ranges, both coefficients are functionally equivalent.
