KTR03EZPJ360 Equivalent & Substitute Parts

Part Overview

The KTR03EZPJ360 is a 36 Ohm ±5% thick film chip resistor rated at 0.1W (1/10W) in 0603 (1608 Metric) package format. Manufactured by Rohm Semiconductor, this component is AEC-Q200 automotive qualified and designed for high-voltage applications. The part is currently active in production with 1067 units in stock.

Equivalent and substitute parts are necessary when the primary part becomes unavailable, when alternative manufacturers offer superior inventory levels, or when design requirements permit tolerance or feature variations within the same electrical and mechanical specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the KTR03EZPJ360 is determined by the following criteria:

Primary Substitutes (Direct Equivalents): Parts matching all electrical parameters (36 Ohms, ±5% tolerance, 0.1W power rating) and mechanical specifications (0603 package, thick film composition, -55°C to 155°C operating range, AEC-Q200 automotive qualification).

Secondary Substitutes (Tolerance Upgrades): Parts with identical resistance, power rating, and package but featuring ±1% tolerance instead of ±5%. These provide improved accuracy while maintaining full mechanical and thermal compatibility. Temperature coefficient may vary (±100ppm/°C vs. ±200ppm/°C).

Tertiary Substitutes (Feature Variants): Parts with matching core electrical and mechanical specifications but differing in secondary features such as moisture resistance or automotive qualification status. These remain functionally compatible within the same package and thermal envelope.

All substitute parts listed maintain the following non-negotiable parameters:

Resistance value: 36 Ohms
Package format: 0603 (1608 Metric)
Power rating: 0.1W (1/10W)
Operating temperature: -55°C to 155°C
Composition: Thick film
RoHS3 compliance
MSL 1 rating

Engineering Selection Recommendations

For AEC-Q200 Automotive Applications: Select from ERJ-3GEYJ360V (Panasonic), RMCF0603JT36R0 (Stackpole), or CRCW060336R0JNEA (Vishay Dale). All three maintain active production status, AEC-Q200 qualification, and ±5% tolerance matching the original KTR03EZPJ360. ERJ-3GEYJ360V offers the highest inventory availability at 90,081 units.

For Tolerance-Critical Applications: ERJ-3EKF36R0V (Panasonic) or RMCF0603FT36R0 (Stackpole) provide ±1% tolerance with AEC-Q200 qualification and active status. ERJ-3EKF36R0V has superior inventory depth at 152,314 units.

For Non-Automotive Applications with High Inventory Requirements: RC0603FR-0736RL (YAGEO) offers ±1% tolerance with 297,590 units in stock, though it lacks AEC-Q200 certification. RC0603JR-0736RL (YAGEO) provides ±5% tolerance with 38,466 units available.

Avoid: MCR03ERTF36R0 (Rohm) is discontinued at the distributor level despite active manufacturer status.

Frequently Asked Questions (FAQ)

Q: Can I use a ±1% tolerance part as a substitute for the ±5% KTR03EZPJ360?

A: Yes. A ±1% tolerance part is a direct functional upgrade. It provides tighter resistance accuracy while maintaining identical electrical performance, power rating, package format, and thermal characteristics. No circuit redesign is required.

Q: What is the difference between AEC-Q200 and non-AEC-Q200 parts?

A: AEC-Q200 certification indicates the part meets automotive industry reliability and qualification standards. For automotive applications, AEC-Q200 parts are required. For consumer or industrial applications, non-certified parts are acceptable if other electrical and mechanical parameters match.

Q: Are all 0603 packages mechanically identical?

A: The 0603 (1608 Metric) package format is standardized. All listed parts use this package and are mechanically interchangeable on PCBs designed for 0603 components. Minor dimensional variations (e.g., 0.061" vs. 0.063" length) fall within standard tolerance and do not affect board-level compatibility.

Q: Can I substitute a part with ±200ppm/°C temperature coefficient with one rated ±100ppm/°C?

A: Yes. Lower temperature coefficient values indicate better stability across temperature ranges. A ±100ppm/°C part will perform equal to or better than a ±200ppm/°C part in the same application. No circuit modification is necessary.

Q: Why do some substitutes have different inventory levels?

A: Inventory levels reflect distributor stock at the time of documentation. Higher inventory availability may indicate broader market adoption, longer production runs, or regional distribution advantages. Inventory should not be the primary selection criterion for one-time designs; prioritize product status and compliance requirements.

Q: Is the KTR03EZPJ360 still available?

A: Yes, the KTR03EZPJ360 is active in production with 1067 units currently in stock. However, alternative parts with higher inventory levels or improved specifications may be preferable for new designs or high-volume production.
