ESR18EZPJ183 Equivalent & Substitute Parts

Part Overview

The ESR18EZPJ183 is an 18 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 696 pieces available in stock. Substitute parts may be required due to inventory constraints, supply chain disruptions, or application-specific power rating requirements.

Substitute Part Grouping Explanation

Substitution eligibility for the ESR18EZPJ183 is determined by the following critical parameters:

• Resistance Value: Must be 18 kOhms
• Tolerance: Must be ±5%
• Package: Must be 1206 (3216 Metric)
• Composition: Must be Thick Film
• Temperature Coefficient: Must be ±200ppm/°C
• Operating Temperature Range: Must be -55°C ~ 155°C
• Automotive Compliance: Must meet AEC-Q200
• RoHS Compliance: Must be ROHS3 Compliant

The ERJ-P08J183V from Panasonic Electronic Components satisfies all substitution criteria. While this part features a higher power rating of 0.667W (2/3W) compared to the 0.5W rating of the main part, this represents a functional upgrade within the same package footprint and does not compromise compatibility in applications designed for the ESR18EZPJ183.

Parameter Comparison

Engineering Selection Recommendations

Both the ESR18EZPJ183 and ERJ-P08J183V are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. The ERJ-P08J183V is a direct functional equivalent with identical electrical characteristics and package dimensions. The increased power rating of the Panasonic part (0.667W versus 0.5W) provides additional thermal margin without introducing any compatibility issues. Both components maintain the same temperature coefficient, operating temperature range, and moisture sensitivity classification. Selection between these parts should be based on availability and supply chain requirements, as both meet all specified engineering parameters for the 1206 thick film 18 kOhms ±5% resistor category.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-P08J183V replace the ESR18EZPJ183 in existing designs?

A: Yes. The ERJ-P08J183V is a direct substitute. Both parts share identical resistance, tolerance, package, composition, temperature coefficient, and operating temperature range. The higher power rating of the Panasonic part does not create compatibility issues.

Q: What is the significance of the different power ratings (0.5W vs 0.667W)?

A: The power rating indicates the maximum power dissipation the resistor can handle. The ERJ-P08J183V with 0.667W rating can safely dissipate more power than the ESR18EZPJ183 at 0.5W. In applications where the ESR18EZPJ183 operates within its 0.5W limit, the ERJ-P08J183V will perform identically with additional thermal headroom.

Q: Are there physical footprint differences between these parts?

A: Both parts use the 1206 (3216 Metric) package with identical length and width (0.126" x 0.063"). The seated height differs slightly (0.026" maximum for Rohm versus 0.028" maximum for Panasonic), which is negligible for standard PCB assembly and does not affect placement or soldering.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both the ESR18EZPJ183 and ERJ-P08J183V carry AEC-Q200 automotive qualification and are ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Q: What determines whether a part can substitute for the ESR18EZPJ183?

A: Substitution requires matching resistance value (18 kOhms), tolerance (±5%), package (1206), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C to 155°C), and automotive compliance (AEC-Q200). Power rating may exceed the original specification without compromising compatibility.
