ESR18EZPJ684 Equivalent & Substitute Parts

Part Overview

The ESR18EZPJ684 is a 680 kOhms ±5% thick film chip resistor in 1206 (3216 Metric) package rated for 0.5W power dissipation. Manufactured by Rohm Semiconductor, this component meets AEC-Q200 automotive qualification standards and features pulse withstanding capability. The part is currently active in production with 1116 units in stock. Substitute parts may be required due to supply constraints, design optimization for higher power ratings, or inventory availability across different manufacturing sources.

Substitute Part Grouping Explanation

The ERJ-P08J684V from Panasonic Electronic Components qualifies as a direct substitute based on the following matching parameters: identical resistance value (680 kOhms), identical tolerance (±5%), identical package format (1206/3216 Metric), identical composition (thick film), identical temperature coefficient (±200ppm/°C), identical operating temperature range (-55°C ~ 155°C), and identical automotive qualification (AEC-Q200). The substitute part features an upgraded power rating of 0.667W (2/3W) compared to the original 0.5W specification, which represents a functional enhancement without introducing incompatibility. Both parts maintain identical physical dimensions (0.126" L x 0.063" W) and identical electrical characteristics within the specified tolerance band.

Parameter Comparison

Engineering Selection Recommendations

Both the ESR18EZPJ684 and ERJ-P08J684V are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. The ERJ-P08J684V provides a higher power dissipation capability (0.667W versus 0.5W) while maintaining all other electrical and mechanical specifications. Selection between these parts should be based on application power requirements and supply availability. The marginal height difference (0.002" / 0.05mm) is negligible for standard PCB assembly processes. Both components are suitable for automotive applications requiring pulse withstanding capability and operate across the full -55°C to 155°C temperature range.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P08J684V replace ESR18EZPJ684 in existing designs? A: Yes. The ERJ-P08J684V is electrically and mechanically compatible. Identical resistance, tolerance, package, and temperature characteristics ensure direct substitution. The higher power rating represents a functional upgrade.

Q: What is the significance of the power rating difference? A: The ERJ-P08J684V is rated for 0.667W versus the original 0.5W. This allows the substitute to dissipate more power without exceeding temperature limits. If your circuit dissipates less than 0.5W through the resistor, both parts perform identically.

Q: Are there package compatibility concerns? A: No. Both parts use the 1206 (3216 Metric) package with identical length and width (0.126" x 0.063"). The height difference of 0.002" is within standard PCB assembly tolerances and does not affect placement or soldering.

Q: Do both parts meet automotive standards? A: Yes. Both ESR18EZPJ684 and ERJ-P08J684V carry AEC-Q200 qualification, suitable for automotive applications. Both are ROHS3 compliant and REACH unaffected.

Q: What determines substitution eligibility for 680 kOhms resistors? A: Substitution requires matching resistance value (680 kOhms), tolerance (±5%), package format (1206), composition (thick film), temperature coefficient (±200ppm/°C), operating range (-55°C to 155°C), and automotive rating (AEC-Q200). Power rating may be equal or higher.
