ESR03EZPJ111 Equivalent & Substitute Parts

Part Overview

The ESR03EZPJ111 is a 110 Ohms ±5% thick film chip resistor in 0603 (1608 Metric) package rated for 0.25W (1/4W) power dissipation. This component is designed for automotive applications and meets AEC-Q200 qualification standards with pulse withstanding capability. The part is currently in active production status with 1024 units available in stock. Substitute parts are identified when equivalent electrical and mechanical specifications are required due to supply constraints, design flexibility, or inventory optimization.

Key Parameters

Substitute Part Grouping Explanation

The ERJ-PA3J111V from Panasonic Electronic Components qualifies as a direct substitute based on the following critical parameters:

• Identical resistance value: 110 Ohms
• Identical tolerance: ±5%
• Identical package: 0603 (1608 Metric)
• Identical composition: Thick Film
• Identical temperature coefficient: ±200ppm/°C
• Identical operating temperature range: -55°C ~ 155°C
• Identical automotive qualification: AEC-Q200
• Identical pulse withstanding feature
• Identical RoHS3 compliance
• Identical MSL rating: 1 (Unlimited)

The only parameter difference is the power rating: the substitute part is rated for 0.333W (1/3W) versus the main part's 0.25W (1/4W). This represents a higher power capability, which does not restrict substitution in applications designed for the lower power rating.

Parameter Comparison

Engineering Selection Recommendations

The ERJ-PA3J111V is a qualified substitute for the ESR03EZPJ111 in automotive applications. Both components maintain identical AEC-Q200 certification, RoHS3 compliance, and environmental specifications. The substitute part's higher power rating (0.333W versus 0.25W) provides additional thermal margin without affecting circuit performance in applications designed for the original 0.25W specification. Both parts are actively produced and available in high volume, supporting long-term supply chain stability. Selection between these parts should be based on availability, lead time, and procurement cost considerations.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-PA3J111V replace the ESR03EZPJ111 in automotive circuits?

A: Yes. Both parts meet AEC-Q200 automotive qualification, share identical electrical specifications (110 Ohms ±5%), and operate across the same temperature range (-55°C ~ 155°C). The substitute part's higher power rating does not restrict its use in applications designed for the original component.

Q: Are the physical dimensions identical?

A: Yes. Both components use the 0603 (1608 Metric) package with identical length (0.063" / 1.60mm), width (0.031" / 0.80mm), and maximum seated height (0.022" / 0.55mm). They are mechanically interchangeable on PCBs designed for 0603 resistors.

Q: What is the significance of the power rating difference?

A: The ERJ-PA3J111V is rated for 0.333W (1/3W) compared to the ESR03EZPJ111's 0.25W (1/4W). This means the substitute part can safely dissipate more power. In applications where the original 0.25W rating is sufficient, the higher rating of the substitute provides additional thermal headroom and does not create compatibility issues.

Q: Are both parts RoHS3 compliant?

A: Yes. Both the ESR03EZPJ111 and ERJ-PA3J111V are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, meeting modern environmental and reliability standards.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes. Both components are supplied in Tape & Reel (TR) packaging for automated assembly and use identical 0603 package specifications. They are compatible with standard SMD pick-and-place equipment and reflow soldering processes.
