ESR03EZPJ154 Equivalent & Substitute Parts

Part Overview

The ESR03EZPJ154 is a 150 kOhms ±5% 0.25W thick film chip resistor in 0603 (1608 Metric) package manufactured by Rohm Semiconductor. This component is AEC-Q200 automotive qualified with pulse withstanding capability, designed for automotive and industrial applications requiring reliable resistive elements in compact form factors. The part is active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Equivalent and substitute parts are identified when components share identical or compatible electrical and mechanical specifications within the allowable parameter tolerances for this product category. Substitutes enable design flexibility, supply chain optimization, and component availability management in production environments.

Substitute Part Grouping Explanation

Substitution eligibility for the ESR03EZPJ154 is determined by the following critical parameters:

Primary Compatibility Criteria:

• Resistance value: 150 kOhms (exact match required)
• Package / Case: 0603 (1608 Metric) (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)
• Automotive qualification: AEC-Q200 (required for automotive applications)
• RoHS compliance: ROHS3 (required for regulatory compliance)

Secondary Compatibility Parameters:

• Tolerance: ±5% or tighter (±1% is acceptable as upgrade)
• Power rating: 0.25W minimum (higher ratings acceptable)
• Temperature coefficient: ±200ppm/°C or better (±100ppm/°C is acceptable as upgrade)
• Composition: Thick film (standard for this category)

Substitute parts are grouped into two categories: upgrade substitutes (improved tolerance and temperature coefficient) and direct substitutes (equivalent or enhanced power rating with same tolerance).

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain active production status and full ROHS3 compliance, ensuring long-term availability and regulatory conformance for automotive applications.

ESR03EZPF1503 (Rohm Semiconductor): This upgrade substitute offers improved tolerance (±1% versus ±5%) and superior temperature coefficient (±100ppm/°C versus ±200ppm/°C) while maintaining identical power rating and package specifications. Selection is appropriate for applications requiring tighter resistance accuracy and enhanced temperature stability. Same manufacturer sourcing simplifies supply chain management.

CRCW0603150KJNEAHP (Vishay Dale): This direct substitute provides enhanced power dissipation capability (0.333W versus 0.25W) in an equivalent 0603 package with matching tolerance and temperature coefficient. The increased power rating offers thermal margin for applications operating near maximum power limits. Dimensional variation (width 0.033" versus 0.031") remains within standard 0603 package tolerance.

ERJ-PA3J154V (Panasonic Electronic Components): This direct substitute delivers equivalent electrical performance with enhanced power rating (0.333W versus 0.25W) and maintains all automotive and compliance certifications. Dimensional specifications match the main part exactly, ensuring direct footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can ESR03EZPF1503 be used as a direct replacement for ESR03EZPJ154?

A: Yes. ESR03EZPF1503 is a direct functional replacement with superior specifications. The ±1% tolerance and ±100ppm/°C temperature coefficient represent improvements over the main part's ±5% tolerance and ±200ppm/°C coefficient. Both parts share identical 0603 package, 0.25W power rating, and AEC-Q200 automotive qualification. No circuit redesign is required.

Q: What is the difference between the upgrade substitute and direct substitutes?

A: ESR03EZPF1503 is classified as an upgrade substitute due to tighter tolerance and improved temperature coefficient specifications. CRCW0603150KJNEAHP and ERJ-PA3J154V are direct substitutes offering equivalent tolerance and temperature coefficient but with increased power rating (0.333W). All three parts are electrically and mechanically compatible with the main part.

Q: Are there dimensional differences between substitute parts?

A: CRCW0603150KJNEAHP has a width specification of 0.033" (0.85mm) compared to 0.031" (0.80mm) for the main part and other substitutes. This variation remains within standard 0603 package tolerance and does not affect PCB footprint compatibility. Height specifications are identical across all parts at 0.022" (0.55mm) maximum.

Q: Do all substitute parts maintain AEC-Q200 automotive qualification?

A: Yes. All identified substitute parts carry AEC-Q200 automotive qualification and are suitable for automotive applications requiring this certification. Operating temperature range (-55°C ~ 155°C) is identical across all parts.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts maintain ROHS3 compliance with MSL 1 (unlimited moisture sensitivity level), matching the regulatory and environmental requirements of the main part.

Q: Can substitute parts be mixed in the same production batch?

A: Yes. All substitute parts are functionally equivalent within the specified parameter tolerances and can be used interchangeably in production. However, design documentation should specify the acceptable part numbers to maintain traceability and ensure consistent performance characteristics across manufactured units.
