Key Parameters

Substitute Part Grouping Explanation

Substitution of the ESR18EZPJ3R9 is permissible when the following criteria are met:

• Resistance value matches exactly: 3.9 Ohms
• Tolerance specification matches: ±5%
• Package footprint is identical: 1206 (3216 Metric)
• Composition type matches: Thick Film
• Temperature coefficient matches: ±200ppm/°C
• Operating temperature range encompasses or matches: -55°C ~ 155°C
• Automotive qualification maintained: AEC-Q200
• RoHS compliance status maintained: ROHS3 Compliant
• Moisture sensitivity level maintained: MSL 1

The CRCW12063R90JNEAHP from Vishay Dale qualifies as a substitute because it maintains all critical electrical parameters and package specifications. The increased power rating (0.75W vs 0.5W) represents an upgrade that does not compromise compatibility in applications designed for the original 0.5W specification.

Parameter Comparison

Engineering Selection Recommendations

The CRCW12063R90JNEAHP is electrically and mechanically compatible with the ESR18EZPJ3R9 for direct substitution in 1206 package applications. Both components maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 moisture sensitivity rating. The substitute part offers increased power dissipation capability (0.75W versus 0.5W), which provides additional thermal margin in circuit designs without introducing incompatibility. Physical dimensions remain within specification for PCB assembly compatibility. Selection between these parts should be based on availability, lead time, and cost considerations, as electrical performance and reliability characteristics are equivalent within the specified operating parameters.

Frequently Asked Questions (FAQ)

Q: Can CRCW12063R90JNEAHP replace ESR18EZPJ3R9 in existing designs?

A: Yes. Both components share identical resistance value (3.9 Ohms), tolerance (±5%), package footprint (1206), composition (thick film), temperature coefficient (±200ppm/°C), and automotive qualification (AEC-Q200). The substitute part's higher power rating (0.75W) does not create compatibility issues in applications designed for 0.5W operation.

Q: Are there physical dimension differences between these parts?

A: Minor dimensional variations exist. ESR18EZPJ3R9 measures 0.126" L × 0.063" W (3.20mm × 1.60mm), while CRCW12063R90JNEAHP measures 0.122" L × 0.063" W (3.10mm × 1.60mm). Both maintain 0.026" (0.65mm) maximum seated height. These differences remain within standard 1206 package tolerances and do not affect PCB assembly compatibility.

Q: Do both parts meet the same compliance standards?

A: Yes. Both components are ROHS3 compliant, REACH unaffected, classified as EAR99 for export control, and carry MSL 1 (unlimited) moisture sensitivity rating. Automotive AEC-Q200 qualification is maintained on both parts.

Q: What is the temperature coefficient significance for substitution?

A: Both parts specify ±200ppm/°C temperature coefficient and operate across -55°C to 155°C. This matching specification ensures equivalent thermal stability and drift characteristics across the full operating temperature range.

Q: Are there packaging format differences?

A: Both components are supplied in Tape & Reel (TR) format. Supplier device package designation is 1206 for both parts, ensuring compatibility with standard SMD assembly equipment and processes.
