ESR03EZPJ274 Equivalent & Substitute Parts

Part Overview

The ESR03EZPJ274 is a 270 kOhms ±5% thick film chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This component is rated for automotive applications under AEC-Q200 standard with pulse withstanding capability and operates across -55°C to 155°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical specifications are required due to inventory constraints, supply chain considerations, or design flexibility needs.

Substitute Part Grouping Explanation

The ERJ-PA3J274V from Panasonic Electronic Components qualifies as a direct substitute based on the following alignment of critical parameters:

• Identical resistance value: 270 kOhms
• Identical tolerance: ±5%
• Identical package: 0603 (1608 Metric)
• Identical physical dimensions: 0.063" L x 0.031" W (1.60mm x 0.80mm)
• Identical composition: Thick Film
• Identical temperature coefficient: ±200ppm/°C
• Identical operating temperature range: -55°C ~ 155°C
• Identical automotive certification: AEC-Q200
• Identical RoHS compliance: ROHS3
• Identical MSL rating: 1 (Unlimited)

The substitute part features a higher power rating (0.333W / 1/3W versus 0.25W / 1/4W), which represents an upward-compatible specification that does not restrict application in circuits designed for the original part.

Parameter Comparison

Engineering Selection Recommendations

Both the ESR03EZPJ274 and ERJ-PA3J274V are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on availability, lead time, and cost considerations. The Panasonic ERJ-PA3J274V offers a higher power dissipation capability (0.333W versus 0.25W), making it suitable for applications where thermal margin is beneficial. Both components meet identical electrical performance requirements, dimensional specifications, and environmental operating conditions. No functional or reliability trade-offs exist between these alternatives.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PA3J274V replace ESR03EZPJ274 in existing designs?

A: Yes. The ERJ-PA3J274V is electrically and mechanically compatible. Identical resistance, tolerance, temperature coefficient, and operating range ensure functional equivalence. The higher power rating of the substitute part does not create compatibility issues.

Q: Are there differences in automotive qualification?

A: No. Both parts carry AEC-Q200 certification, meeting identical automotive reliability and quality standards.

Q: Do these parts have the same physical footprint?

A: Yes. Both components use the 0603 (1608 Metric) package with identical dimensions (0.063" L x 0.031" W, 1.60mm x 0.80mm) and maximum seated height (0.022" / 0.55mm). PCB layout and assembly processes require no modification.

Q: What is the significance of the different power ratings?

A: The ERJ-PA3J274V is rated for 0.333W (1/3W) compared to the ESR03EZPJ274 at 0.25W (1/4W). This represents an upward-compatible specification. Circuits designed for 0.25W operation will function within the thermal limits of the 0.333W component.

Q: Are moisture sensitivity levels equivalent?

A: Yes. Both parts have MSL 1 (Unlimited) rating, indicating no moisture-related handling restrictions during storage, transport, or assembly.

Q: Do both parts comply with environmental regulations?

A: Yes. Both are ROHS3 compliant and REACH unaffected, meeting current environmental and hazardous substance restrictions.
