ESR03EZPJ133 Equivalent & Substitute Parts

Part Overview

The ESR03EZPJ133 is a 13 kOhms ±5% thick film chip resistor manufactured by Rohm Semiconductor in 0603 (1608 Metric) package format. This component is rated for 0.25W (1/4W) power dissipation and meets automotive AEC-Q200 qualification standards with pulse withstanding capability. The part is currently in active production status with 2,819 units available in inventory. Substitute parts are identified when equivalent electrical characteristics, mechanical compatibility, and automotive compliance ratings are maintained across alternative manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the ESR03EZPJ133 is determined by the following critical parameters:

• Resistance value: 13 kOhms (exact match required)
• Tolerance: ±5% (exact match required)
• Package format: 0603 (1608 Metric) (exact match required)
• Composition: Thick Film (exact match required)
• Temperature Coefficient: ±200ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 155°C (exact match required)
• Automotive Compliance: AEC-Q200 (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The ERJ-PA3J133V from Panasonic Electronic Components satisfies all substitution criteria. While the power rating differs (0.333W versus 0.25W), the higher power rating of the substitute part maintains full compatibility in applications designed for the original 0.25W specification, as it represents a derating margin rather than a functional limitation.

Parameter Comparison

Engineering Selection Recommendations

Both the ESR03EZPJ133 and ERJ-PA3J133V are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on supply chain availability and lead time requirements. The ERJ-PA3J133V offers a higher power rating (0.333W versus 0.25W) within the same physical package, providing additional thermal margin in applications where the original 0.25W specification is met. Both components maintain identical electrical characteristics, temperature performance, and mechanical compatibility for direct substitution in 0603 package footprints.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PA3J133V replace ESR03EZPJ133 in automotive applications?

A: Yes. Both components meet AEC-Q200 automotive qualification standards and maintain identical resistance, tolerance, temperature coefficient, and operating temperature range specifications. The higher power rating of the ERJ-PA3J133V (0.333W) is compatible with designs specified for 0.25W operation.

Q: Are the physical dimensions identical?

A: Yes. Both parts 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). PCB footprints are directly interchangeable.

Q: Do both parts have the same moisture sensitivity rating?

A: Yes. Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

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

A: The ERJ-PA3J133V power rating of 0.333W (1/3W) exceeds the ESR03EZPJ133 specification of 0.25W (1/4W). In applications designed for 0.25W dissipation, the higher-rated substitute provides additional thermal margin and represents a conservative design choice.

Q: Are both parts RoHS compliant?

A: Yes. Both ESR03EZPJ133 and ERJ-PA3J133V are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.
