ESR03EZPJ393 Equivalent & Substitute Parts

Part Overview

The ESR03EZPJ393 is a 39 kOhms ±5% thick film chip resistor manufactured by Rohm Semiconductor in 0603 (1608 Metric) package format. This component is rated for automotive applications under AEC-Q200 standard with pulse withstanding capability and operates across -55°C to 155°C temperature range. The part is currently in active production status. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and automotive compliance ratings are maintained across alternative manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the ESR03EZPJ393 is determined by the following critical parameters:

• Resistance value: 39 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 or better required)
• Automotive Compliance: AEC-Q200 (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)

The ERJ-PA3J393V from Panasonic Electronic Components meets all substitution criteria. While the power rating differs (0.333W versus 0.25W), the higher power rating represents a design margin improvement and does not restrict substitution in applications designed for the original 0.25W specification.

Parameter Comparison

Engineering Selection Recommendations

Both the ESR03EZPJ393 and ERJ-PA3J393V are active production components with identical AEC-Q200 automotive compliance ratings and ROHS3 certification status. Selection between these parts should be based on availability, lead time, and supply chain requirements. The ERJ-PA3J393V offers higher power dissipation capability (0.333W versus 0.25W) within the same physical package, providing additional thermal margin in applications operating near maximum power specifications. Both components satisfy identical electrical, mechanical, and environmental requirements for automotive-grade 39 kOhms resistor applications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PA3J393V replace ESR03EZPJ393 in existing designs?

A: Yes. Both parts share identical resistance, tolerance, package dimensions, temperature coefficient, operating temperature range, and AEC-Q200 automotive compliance. The higher power rating of the Panasonic part does not restrict substitution in circuits designed for the original 0.25W specification.

Q: Are the physical dimensions identical?

A: Yes. Both parts are packaged in 0603 (1608 Metric) format with identical length (0.063" / 1.60mm), width (0.031" / 0.80mm), and maximum seated height (0.022" / 0.55mm). PCB footprints are interchangeable.

Q: Do both parts meet automotive compliance requirements?

A: Yes. Both ESR03EZPJ393 and ERJ-PA3J393V carry AEC-Q200 automotive qualification and ROHS3 compliance certification. Both are suitable for automotive-grade applications.

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

A: The ERJ-PA3J393V power rating of 0.333W (1/3W) exceeds the ESR03EZPJ393 specification of 0.25W (1/4W). This represents improved thermal performance within the same package size and does not create compatibility issues when substituting into designs specified for 0.25W operation.

Q: Are moisture sensitivity levels equivalent?

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