ESR18EZPJ273 Equivalent & Substitute Parts

Part Overview

The ESR18EZPJ273 is a 27 kOhms ±5% thick film chip resistor in 1206 (3216 Metric) package rated for 0.5W power dissipation. Manufactured by Rohm Semiconductor, this component is designed for automotive applications and carries AEC-Q200 qualification with pulse withstanding capability. The part is currently active in production with 3908 units in stock. Equivalent and substitute parts may be required due to supply chain constraints, design optimization for higher power ratings, or procurement preferences.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESR18EZPJ273 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 27 kOhms
• Tolerance: ±5%
• Package: 1206 (3216 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C to 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant

Allowable Variation:

• Power rating may be equal to or greater than the original 0.5W specification, provided the physical dimensions remain compatible with the 1206 package footprint and do not exceed the maximum seated height constraint of the application.

The ERJ-P08J273V from Panasonic Electronic Components qualifies as a direct substitute based on matching all mandatory parameters while offering an increased power rating of 0.667W (2/3W), which provides additional thermal margin without compromising form factor compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the ESR18EZPJ273 and ERJ-P08J273V are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on:

ESR18EZPJ273 (Rohm Semiconductor): Select when the original design specification calls for 0.5W power rating and Rohm supply chain preference is established. Current inventory of 3908 units supports immediate availability.

ERJ-P08J273V (Panasonic Electronic Components): Select when higher thermal margin is required within the same package footprint, or when Panasonic supply chain is preferred. The 0.667W rating provides 33% additional power dissipation capacity. Current inventory of 2989 units is available. The maximum seated height of 0.028" (0.70mm) versus 0.026" (0.65mm) must be verified against PCB clearance constraints in space-critical applications.

Both parts maintain identical electrical performance characteristics and environmental ratings across the full operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P08J273V be used as a direct replacement for ESR18EZPJ273 in existing designs?

A: Yes. The ERJ-P08J273V is electrically and mechanically compatible. Both parts share identical resistance value, tolerance, temperature coefficient, and operating temperature range. The higher power rating of ERJ-P08J273V (0.667W vs 0.5W) does not create compatibility issues. Verify that the maximum seated height difference of 0.002" (0.05mm) does not conflict with PCB assembly constraints or component clearance requirements.

Q: Are there any thermal performance differences between these parts?

A: The ERJ-P08J273V offers higher power dissipation capacity (0.667W vs 0.5W) within the same 1206 package, resulting in lower junction temperature under identical load conditions. Both parts maintain the same temperature coefficient of ±200ppm/°C across the -55°C to 155°C operating range.

Q: Do both parts meet automotive qualification requirements?

A: Yes. Both ESR18EZPJ273 and ERJ-P08J273V carry AEC-Q200 qualification, confirming suitability for automotive applications. Both are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the impact of the 0.002" height difference on PCB assembly?

A: The ERJ-P08J273V maximum seated height is 0.028" (0.70mm) compared to 0.026" (0.65mm) for the ESR18EZPJ273. This 0.002" (0.05mm) difference is negligible for most applications but must be verified in designs with tight vertical clearance constraints, such as stacked component layouts or confined enclosures.

Q: Can these parts be used interchangeably in high-reliability applications?

A: Yes. Both parts are active production components with identical electrical specifications, automotive qualification, and compliance certifications. Interchangeability is supported from an engineering standpoint. Verify component qualification status with your procurement and quality assurance departments per your organization's change control procedures.
