ESR10EZPJ180 Equivalent & Substitute Parts

Part Overview

The ESR10EZPJ180 is an 18 Ohm ±5% 0.4W thick film chip resistor in 0805 (2012 Metric) package manufactured by Rohm Semiconductor. This component is rated for automotive applications under AEC-Q200 standard with pulse withstanding capability and operates across -55°C to 155°C. The part is currently in active production status with 5125 units available in inventory.

Substitute parts become necessary when the original component reaches end-of-life status, inventory constraints occur, or design requirements shift toward enhanced specifications such as improved tolerance or higher power ratings while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ESR10EZPJ180 are qualified based on the following electrical and mechanical parameters:

Primary Compatibility Criteria:

• Resistance value: 18 Ohms (exact match required)
• Package type: 0805 (2012 Metric) (exact match required)
• Operating temperature range: -55°C to 155°C (minimum requirement)
• Automotive certification: AEC-Q200 (required for automotive applications)
• Composition: Thick Film (required for pulse withstanding capability)
• RoHS compliance: ROHS3 Compliant (required for regulatory compliance)

Allowable Parameter Variations:

• Tolerance: May be equal or tighter (±5% or better)
• Power rating: May be equal or higher (0.4W or greater)
• Temperature coefficient: ±200ppm/°C or better
• Additional features: Anti-sulfur or enhanced pulse withstanding are acceptable enhancements

Two substitute parts meet these criteria: ERJ-P6WF18R0V (Panasonic, tighter tolerance, higher power) and ERJ-UP6J180V (Panasonic, matching tolerance, higher power with anti-sulfur feature).

Engineering Selection Recommendations

For Active Production Designs: ERJ-UP6J180V is the primary substitute for the ESR10EZPJ180. Both components maintain active product status, ensuring long-term availability and supply chain stability. The ERJ-UP6J180V provides identical electrical specifications (18 Ohms ±5%) with enhanced mechanical performance through anti-sulfur coating and increased power rating (0.5W vs 0.4W). All automotive certifications, RoHS compliance, and thermal specifications remain equivalent.

For Legacy or Cost-Optimized Designs: ERJ-P6WF18R0V offers tighter tolerance (±1% vs ±5%) and higher power rating (0.5W) but carries "Not For New Designs" status from the manufacturer. This part is suitable only for replacement in existing production runs where component availability from the original manufacturer becomes constrained. The tighter tolerance may provide improved circuit performance in precision applications.

Compliance Considerations: All three parts maintain ROHS3 compliance, AEC-Q200 automotive certification, and MSL 1 moisture sensitivity rating. No regulatory or environmental restrictions apply to substitution between these components.

Frequently Asked Questions (FAQ)

Q: Can ERJ-P6WF18R0V replace ESR10EZPJ180 in new designs? A: ERJ-P6WF18R0V is electrically compatible but carries "Not For New Designs" status. For new production, ERJ-UP6J180V is the recommended substitute.

Q: What is the difference between the two Panasonic substitutes? A: ERJ-UP6J180V matches the original tolerance (±5%) and adds anti-sulfur protection. ERJ-P6WF18R0V provides tighter tolerance (±1%) but is discontinued for new designs. Both offer 0.5W power rating versus the original 0.4W.

Q: Are the physical dimensions identical between all three parts? A: All three parts use the 0805 (2012 Metric) package. Length and width are identical (2.00mm x 1.25mm). Maximum seated heights vary slightly: ESR10EZPJ180 at 0.65mm, ERJ-UP6J180V at 0.70mm, and ERJ-P6WF18R0V at 0.75mm. These variations remain within standard PCB assembly tolerances.

Q: Can I use a higher power rating resistor as a substitute? A: Yes. The 0.5W rating of both Panasonic substitutes exceeds the original 0.4W specification. Higher power ratings provide additional thermal margin and are electrically compatible in circuits designed for the original component.

Q: Are there any temperature or environmental restrictions for substitution? A: No. All three parts operate across -55°C to 155°C with identical temperature coefficients (±200ppm/°C) and MSL 1 moisture sensitivity. Substitution is unrestricted for automotive and industrial temperature ranges.

Q: What is the significance of the anti-sulfur feature in ERJ-UP6J180V? A: Anti-sulfur coating protects the resistor from corrosion in high-sulfur environments, extending component life in harsh automotive or industrial applications. This is an enhancement that does not affect electrical compatibility.
