ERJ-8RQJ3R6V Equivalent & Substitute Parts

Part Overview

The ERJ-8RQJ3R6V is a 3.6 Ohm ±5% 0.25W thick film chip resistor in 1206 (3216 Metric) package manufactured by Panasonic Electronic Components. This component is rated for automotive applications under AEC-Q200 and is designed for current sense applications. The part is active and in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when design requirements allow for tolerance upgrades, power rating increases, or manufacturer alternatives while maintaining the same resistance value, package form factor, and core electrical characteristics.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Upgrade Substitutes — Parts with identical resistance (3.6 Ohms), same package (1206), same composition (thick film), and same operating temperature range, but with improved tolerance (±1%) or increased power rating (0.5W). These parts are direct functional upgrades and are interchangeable in applications where the original specifications are met or exceeded.

Similar Substitutes — Parts from alternative manufacturers (YAGEO) with identical resistance (3.6 Ohms), same package (1206), same composition (thick film), and same operating temperature range. These maintain core electrical performance and package compatibility. Tolerance and power rating may vary based on design requirements.

All substitute parts maintain:

Resistance value: 3.6 Ohms
Package form factor: 1206 (3216 Metric)
Thick film composition
Temperature coefficient: ±200ppm/°C
Operating temperature: -55°C ~ 155°C
RoHS3 compliance
MSL 1 rating

Engineering Selection Recommendations

For Panasonic Automotive AEC-Q200 Applications:

ERJ-8BQF3R6V and ERJ-8BQJ3R6V are direct Panasonic upgrades maintaining full AEC-Q200 automotive qualification. ERJ-8BQF3R6V provides improved tolerance (±1%) with increased power rating (0.5W). ERJ-8BQJ3R6V maintains ±5% tolerance with increased power rating (0.5W). Both are suitable where higher power dissipation or tighter tolerance is required.

For Non-Automotive or General Industrial Applications:

AC1206FR-073R6L and RC1206FR-073R6L from YAGEO provide equivalent electrical performance with ±1% tolerance and 0.25W power rating. AC1206FR-073R6L maintains AEC-Q200 rating. RC1206FR-073R6L does not carry AEC-Q200 rating and is suitable for non-automotive applications.

RC1206JR-073R6L from YAGEO matches the original ±5% tolerance and 0.25W power rating without AEC-Q200 automotive qualification.

Selection Criteria:

Automotive applications requiring AEC-Q200: Select from Panasonic ERJ-8 series or YAGEO AC1206FR-073R6L
Applications requiring ±1% tolerance: Select ERJ-8BQF3R6V, AC1206FR-073R6L, or RC1206FR-073R6L
Applications requiring higher power dissipation: Select ERJ-8BQF3R6V or ERJ-8BQJ3R6V (0.5W rating)
Non-automotive general purpose: YAGEO RC series options are suitable

Frequently Asked Questions (FAQ)

Q: Can ERJ-8BQF3R6V replace ERJ-8RQJ3R6V in all applications?

A: ERJ-8BQF3R6V is a functional upgrade with improved tolerance (±1% vs ±5%) and higher power rating (0.5W vs 0.25W). It is interchangeable in the same 1206 package and maintains AEC-Q200 automotive qualification. Verify that the circuit design does not depend on the original ±5% tolerance specification.

Q: What is the difference between Panasonic and YAGEO substitutes?

A: Panasonic ERJ-8 series parts maintain full AEC-Q200 automotive qualification. YAGEO AC1206FR-073R6L also carries AEC-Q200 rating. YAGEO RC1206 series parts do not carry automotive qualification and are suitable for industrial and consumer applications. All maintain identical 1206 package form factor and ±200ppm/°C temperature coefficient.

Q: Are there dimensional differences between manufacturers?

A: Panasonic ERJ-8RQJ3R6V dimensions are 0.126" L x 0.063" W (3.20mm x 1.60mm) with 0.028" max height. YAGEO AC and RC series dimensions are 0.122" L x 0.063" W (3.10mm x 1.60mm) with 0.026" max height. Both fit the 1206 package specification. Verify PCB layout tolerances for critical applications.

Q: Can I use a 0.5W rated part in place of a 0.25W part?

A: Yes. A higher power rating part (0.5W) is suitable for applications originally designed for 0.25W. The component will operate within safe thermal limits. Verify that circuit current and voltage do not exceed the original 0.25W specification if thermal management is critical.

Q: Which substitute offers the best tolerance for precision circuits?

A: ERJ-8BQF3R6V, AC1206FR-073R6L, and RC1206FR-073R6L all offer ±1% tolerance compared to the original ±5%. Select based on automotive qualification requirement: ERJ-8BQF3R6V or AC1206FR-073R6L for AEC-Q200 applications, RC1206FR-073R6L for non-automotive use.

Q: Are all substitutes RoHS3 compliant?

A: Yes. All listed substitute parts are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating, matching the original ERJ-8RQJ3R6V specifications.
