ESR10EZPJ274 Equivalent & Substitute Parts

Part Overview

The ESR10EZPJ274 is a 270 kOhms ±5% 0.4W thick film chip resistor in 0805 (2012 Metric) package manufactured by Rohm Semiconductor. This automotive-grade component meets AEC-Q200 qualification and features pulse withstanding capability, making it suitable for demanding automotive and industrial applications. The part is currently active in production with 712 units in stock.

Substitute parts are necessary when the original manufacturer discontinues production, when higher power ratings are required for thermal margin, or when tighter tolerance specifications improve circuit performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESR10EZPJ274 is determined by the following criteria:

Mandatory Parameters (Must Match):

• Resistance value: 270 kOhms
• Package: 0805 (2012 Metric)
• Composition: Thick Film
• Temperature Coefficient: ±200ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Automotive Rating: AEC-Q200
• RoHS Compliance: ROHS3 Compliant

Allowable Variations:

• Tolerance: ±5% or tighter (±1% acceptable as upgrade)
• Power Rating: 0.4W or higher (0.5W acceptable as upgrade)
• Manufacturer: Different manufacturers permitted if all mandatory parameters match
• Product Status: Active or Not For New Designs both acceptable for substitution

The three substitute parts (ERJ-P06J274V, ERJ-P6WF2703V, ERJ-P6WJ274V) all meet these criteria with variations in tolerance and power rating that represent functional upgrades or equivalent alternatives.

Parameter Comparison

Engineering Selection Recommendations

ERJ-P06J274V (Panasonic): This substitute maintains ±5% tolerance matching the original specification while providing increased power rating (0.5W vs 0.4W). The part is currently active in production with 20,425 units in stock. Physical height increases by 0.002" (0.05mm), which remains within typical PCB layout tolerances for 0805 packages. This represents the preferred direct substitute for new designs.

ERJ-P6WF2703V (Panasonic): This substitute offers tighter tolerance (±1% vs ±5%) with 0.5W power rating. Product status is Not For New Designs, limiting its use to legacy or maintenance applications. Height increases to 0.030" (0.75mm). Selection of this part is appropriate only when tighter tolerance specifications are required and design freeze permits use of legacy components.

ERJ-P6WJ274V (Panasonic): This substitute maintains ±5% tolerance with 0.5W power rating. Product status is Not For New Designs. Height is 0.030" (0.75mm). This part is suitable for replacement in existing designs but not recommended for new development.

All three substitutes maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating, ensuring compatibility with automotive and industrial applications requiring these certifications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P06J274V be used as a direct replacement for ESR10EZPJ274?

A: Yes. Both parts share identical resistance (270 kOhms), tolerance (±5%), package (0805), composition (thick film), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and AEC-Q200 rating. The ERJ-P06J274V provides higher power rating (0.5W vs 0.4W) and is currently active in production.

Q: What is the significance of the power rating difference between 0.4W and 0.5W?

A: Power rating indicates the maximum continuous power dissipation the resistor can handle. The 0.5W rating provides additional thermal margin compared to 0.4W. In applications where the ESR10EZPJ274 operates near its power limit, upgrading to 0.5W improves reliability and thermal performance.

Q: Why are ERJ-P6WF2703V and ERJ-P6WJ274V marked as "Not For New Designs"?

A: This product status indicates the manufacturer has discontinued or is phasing out these parts. They remain available for existing designs and maintenance applications but should not be selected for new product development. ERJ-P06J274V is the recommended substitute for new designs.

Q: Does the height difference (0.026" to 0.030") affect PCB layout?

A: The maximum height variation is 0.004" (0.10mm) across all substitutes. This falls within standard PCB design tolerances for 0805 packages and does not require layout modifications for typical applications.

Q: Are all substitutes automotive-qualified?

A: Yes. All three substitute parts maintain AEC-Q200 qualification, ROHS3 compliance, and MSL 1 rating, ensuring compatibility with automotive and industrial applications.

Q: Can ERJ-P6WF2703V be used when tighter tolerance is required?

A: Yes. The ±1% tolerance of ERJ-P6WF2703V is tighter than the ±5% specification of the original part. However, product status is Not For New Designs. Use this part only in legacy applications or when design constraints permit use of discontinued components.
