Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Primary Matching Parameters:

Resistance value: 200 kOhms (exact match required)
Package / Case: 0603 (1608 Metric) (exact match required)
Composition: Thick Film (exact match required)
Operating Temperature Range: -55°C ~ 155°C (exact match required)
Automotive Rating: AEC-Q200 (exact match required)
RoHS Status: ROHS3 Compliant (exact match required)

Secondary Allowable Variations:

Tolerance: ±5% or tighter (±1% acceptable as upgrade)
Power Rating: 0.25W or higher (0.333W acceptable as upgrade)
Temperature Coefficient: ±200ppm/°C or better (±100ppm/°C acceptable as upgrade)
Manufacturer: Different manufacturers permitted if all primary parameters match

All identified substitute parts meet or exceed the primary matching parameters of the ESR03EZPJ204.

Engineering Selection Recommendations

All identified substitute parts maintain active product status and full compliance with ROHS3 and AEC-Q200 automotive qualification requirements. Selection among equivalent parts should be based on:

ESR03EZPF2003 (Rohm Semiconductor): Upgrade option offering improved tolerance (±1% vs ±5%) and superior temperature coefficient (±100ppm/°C vs ±200ppm/°C) while maintaining identical power rating and package specifications. Same manufacturer as primary part.

CRCW0603200KJNEAHP (Vishay Dale): Direct equivalent with identical tolerance and temperature coefficient. Provides higher power dissipation capability (0.333W vs 0.25W) within the same 0603 package footprint.

ERJ-PA3J204V (Panasonic Electronic Components): Direct equivalent with identical tolerance and temperature coefficient. Provides higher power dissipation capability (0.333W vs 0.25W) within the same 0603 package footprint.

RCS0603200KJNEA (Vishay Dale): Direct equivalent matching all primary electrical and thermal specifications with identical power rating and tolerance.

All parts are suitable for direct substitution in automotive applications requiring 200 kOhms ±5% 0.25W thick film resistors in 0603 package format.

Frequently Asked Questions (FAQ)

Q: Can ESR03EZPF2003 be used as a direct replacement for ESR03EZPJ204?

A: Yes. ESR03EZPF2003 is a direct substitute with improved tolerance (±1%) and temperature coefficient (±100ppm/°C). It maintains identical power rating, package, and automotive qualification. The tighter tolerance represents an upgrade path.

Q: What is the difference between 0.25W and 0.333W power ratings in the 0603 package?

A: Both ratings are within the 0603 (1608 Metric) package specification. The 0.333W rating indicates higher power dissipation capability. Parts with 0.333W rating (CRCW0603200KJNEAHP, ERJ-PA3J204V) can be substituted for 0.25W applications without functional impact.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All identified substitute parts carry AEC-Q200 automotive qualification, meeting the same reliability and qualification standards as the ESR03EZPJ204.

Q: Do substitute parts have identical physical dimensions?

A: All parts use the 0603 (1608 Metric) package. Minor dimensional variations exist within manufacturer tolerances (height range 0.020" to 0.022", length range 0.061" to 0.063", width range 0.031" to 0.033"). These variations are within standard PCB design tolerances and do not affect mechanical compatibility.

Q: Can parts from different manufacturers be mixed in the same design?

A: Yes. All substitute parts meet identical electrical specifications, package requirements, and automotive certifications. Cross-manufacturer substitution is permissible within the same design.

Q: What is the significance of ±200ppm/°C vs ±100ppm/°C temperature coefficient?

A: Temperature coefficient defines resistance change per degree Celsius. ±100ppm/°C (ESR03EZPF2003) provides superior stability across the -55°C to 155°C operating range compared to ±200ppm/°C. Selection depends on circuit tolerance requirements.
