KTR03EZPJ165 Equivalent & Substitute Parts

Part Overview

The KTR03EZPJ165 is a 1.6 MOhms ±5% thick film chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This component is rated for automotive applications under AEC-Q200 standard with high voltage capability and operates across -55°C to 155°C. The part is currently active in production with 748 units in stock.

Substitute parts become necessary when the original component reaches end-of-life status, inventory constraints occur, or design requirements shift toward tighter tolerance specifications. The KTR03EZPJ165 can be replaced with equivalent resistors that maintain identical electrical performance within the same package footprint while meeting automotive qualification requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the KTR03EZPJ165 is determined by the following criteria:

Electrical Parameters: Resistance value (1.6 MOhms), power rating (0.1W), and operating temperature range (-55°C to 155°C) must remain constant across all substitutes.

Package Compatibility: All substitutes must use the 0603 (1608 Metric) package to ensure PCB footprint compatibility without layout redesign.

Automotive Compliance: All substitutes must maintain AEC-Q200 automotive qualification to preserve design certification and reliability standards.

Environmental Standards: RoHS3 compliance and MSL 1 rating are maintained across all substitute options.

Tolerance Variations: While the main part specifies ±5% tolerance, upgrade substitutes with ±1% tolerance are electrically compatible and provide improved accuracy for circuits where tighter tolerance is beneficial. Direct substitutes maintain ±5% tolerance for drop-in replacement without circuit re-analysis.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (Same Tolerance): The RMCF0603JT1M60 from Stackpole Electronics Inc provides direct substitution with identical ±5% tolerance and ±200ppm/°C temperature coefficient. This part maintains all electrical characteristics of the KTR03EZPJ165 and is currently in active production status with high inventory availability (9974 units).

Upgrade Options (Tighter Tolerance): The KTR03EZPF1604 (Rohm Semiconductor), RMCF0603FT1M60 (Stackpole Electronics Inc), and ERJ-3EKF1604V (Panasonic Electronic Components) offer ±1% tolerance with ±100ppm/°C temperature coefficient. These upgrades are electrically compatible and provide superior accuracy. KTR03EZPF1604 and RMCF0603FT1M60 are active products with substantial inventory. ERJ-3EKF1604V is obsolete and should not be selected for new designs despite current stock availability.

Packaging Consideration: All substitutes use identical 0603 (1608 Metric) package dimensions and maintain AEC-Q200 automotive qualification. Tape & Reel packaging is standard across active products for automated assembly compatibility.

Frequently Asked Questions (FAQ)

Q: Can I use a substitute part with ±1% tolerance in place of the ±5% original? A: Yes. The ±1% tolerance substitute parts are electrically compatible and provide improved accuracy. Since ±1% is a tighter specification than ±5%, any circuit designed for ±5% tolerance will function correctly with ±1% components without circuit re-analysis.

Q: Are all substitute parts qualified for automotive applications? A: All active substitute parts (KTR03EZPF1604, RMCF0603JT1M60, RMCF0603FT1M60) maintain AEC-Q200 automotive qualification identical to the original KTR03EZPJ165. The ERJ-3EKF1604V is also AEC-Q200 qualified but is obsolete and unsuitable for new designs.

Q: Will substitute parts fit the same PCB footprint? A: Yes. All substitute parts use the 0603 (1608 Metric) package with identical footprint dimensions (0.063" L x 0.031" W or 1.60mm x 0.80mm). No PCB layout modifications are required.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel packaging is supplied on continuous reels for high-volume automated assembly. Cut Tape & Digi-Reel packaging is supplied in smaller quantities on cut tape segments. For production environments, Tape & Reel is standard. Cut Tape is typically used for lower-volume or prototype applications.

Q: Why is ERJ-3EKF1604V listed as obsolete? A: Panasonic has discontinued this product line. While current inventory may be available, obsolete parts carry risk of future unavailability and should not be selected for new designs or long-term production requirements.

Q: Do all substitutes maintain the same temperature operating range? A: Yes. All substitute parts operate across -55°C to 155°C, identical to the KTR03EZPJ165. Temperature coefficient values differ between ±200ppm/°C (original and some substitutes) and ±100ppm/°C (upgrade options), but both specifications are within acceptable automotive operating parameters.
