Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESR18EZPJ243 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 24 kOhms
• Tolerance: ±5%
• Package / Case: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±200ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Automotive Rating: AEC-Q200
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Allowable Variation:

• Power Rating: Equal to or greater than 0.5W

The ERJ-P08J243V from Panasonic Electronic Components qualifies as a direct substitute. It maintains all mandatory electrical and mechanical parameters while providing an increased power rating of 0.667W (2/3W), which exceeds the minimum requirement and provides additional thermal margin in the application.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-P08J243V is a qualified substitute for the ESR18EZPJ243 in applications requiring a 24 kOhms ±5% thick film resistor in 1206 package. Both components maintain identical electrical specifications including resistance, tolerance, temperature coefficient, and operating temperature range. Both are AEC-Q200 qualified for automotive use and ROHS3 compliant.

The ERJ-P08J243V provides a higher power rating (0.667W versus 0.5W), which is compatible with the original design and offers improved thermal performance. The maximum seated height difference of 0.002" (0.05mm) is negligible for standard PCB assembly and does not impact board layout or component clearance in typical automotive applications.

Selection between these parts should be based on availability, lead time, cost considerations, and supply chain requirements. Both components are suitable for direct substitution in the same circuit application.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-P08J243V replace the ESR18EZPJ243 in my design?

A: Yes. The ERJ-P08J243V is a direct substitute. It maintains all critical electrical parameters (24 kOhms ±5%, ±200ppm/°C, -55°C to 155°C operating range) and package specifications (1206 / 3216 Metric). Both components are AEC-Q200 qualified and ROHS3 compliant. The higher power rating of the substitute (0.667W) is compatible with designs requiring 0.5W.

Q: Are there any physical differences between these parts?

A: Both components use identical 1206 (3216 Metric) package dimensions of 0.126" L x 0.063" W (3.20mm x 1.60mm). The maximum seated height differs by 0.002" (0.05mm), which is within standard PCB assembly tolerances and does not affect placement or clearance.

Q: Do both parts meet automotive standards?

A: Yes. Both the ESR18EZPJ243 and ERJ-P08J243V are AEC-Q200 qualified automotive components with pulse withstanding capability. Both are ROHS3 compliant and have Moisture Sensitivity Level 1 (Unlimited).

Q: What is the tolerance specification for these resistors?

A: Both parts are specified at ±5% tolerance with a temperature coefficient of ±200ppm/°C across the operating range of -55°C to 155°C.

Q: Can I use these parts interchangeably on the same PCB?

A: Yes. The identical package footprint (1206), electrical specifications, and automotive qualifications make these parts fully interchangeable from both design and assembly perspectives.
