ESR03EZPJ183 Equivalent & Substitute Parts

Part Overview

The ESR03EZPJ183 is an 18 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 and operates across -55°C to 155°C. The part is active in production status and ROHS3 compliant. Equivalent and substitute parts are identified when design requirements allow tolerance relaxation, power rating adjustment, or manufacturer substitution while maintaining electrical and mechanical compatibility within the 0603 package footprint.

Substitute Part Grouping Explanation

Substitution of the ESR03EZPJ183 is determined by the following criteria:

Upgrade Substitutes maintain identical resistance value and package while improving tolerance specification. ESR03EZPF1802 provides ±1% tolerance (tighter than ±5%) with equivalent power rating, temperature range, and AEC-Q200 qualification. This substitution is valid when design specifications require improved tolerance performance.

Direct Manufacturer Substitutes maintain identical resistance, tolerance, and package while allowing power rating increase. ERJ-PA3J183V from Panasonic Electronic Components provides 0.333W (1/3W) rating versus the original 0.25W, with matching ±5% tolerance, temperature range, and AEC-Q200 qualification. This substitution is valid when higher power dissipation capability is required or when Panasonic sourcing is preferred.

All substitute parts share the 0603 (1608 Metric) package footprint, enabling direct PCB placement compatibility. Resistance value (18 kOhms) and automotive qualification (AEC-Q200) remain constant across all substitutes.

Parameter Comparison

Engineering Selection Recommendations

ESR03EZPJ183 remains the primary selection for applications requiring ±5% tolerance, 0.25W power dissipation, and Rohm Semiconductor sourcing within automotive AEC-Q200 environments.

ESR03EZPF1802 is selected when circuit design specifications mandate ±1% tolerance performance. The tighter tolerance and reduced temperature coefficient (±100ppm/°C versus ±200ppm/°C) provide improved stability in precision analog circuits. Both parts are Rohm Semiconductor products with identical package and thermal characteristics.

ERJ-PA3J183V is selected when higher power dissipation capability (0.333W versus 0.25W) is required or when Panasonic Electronic Components supply chain is preferred. The increased power rating provides design margin in high-current applications while maintaining identical resistance value, tolerance, and automotive qualification.

All three parts maintain ROHS3 compliance, MSL Level 1 rating, and AEC-Q200 automotive qualification, ensuring regulatory and reliability requirements are met across substitution scenarios.

Frequently Asked Questions (FAQ)

Q: Can ESR03EZPF1802 replace ESR03EZPJ183 in existing designs?

A: Yes. ESR03EZPF1802 is a direct upgrade substitute with improved ±1% tolerance versus ±5%, identical power rating (0.25W), package (0603), and operating temperature range (-55°C to 155°C). The tighter tolerance and lower temperature coefficient provide enhanced circuit performance without requiring PCB layout changes.

Q: What is the primary difference between ESR03EZPJ183 and ERJ-PA3J183V?

A: The primary difference is the power rating: ESR03EZPJ183 is rated 0.25W (1/4W) while ERJ-PA3J183V is rated 0.333W (1/3W). Both maintain 18 kOhms ±5% resistance, 0603 package, and AEC-Q200 qualification. ERJ-PA3J183V is from Panasonic Electronic Components instead of Rohm Semiconductor.

Q: Are all substitute parts compatible with the original 0603 PCB footprint?

A: Yes. All substitute parts use the 0603 (1608 Metric) package with identical dimensions (0.063" L x 0.031" W, 1.60mm x 0.80mm) and maximum seated height (0.022", 0.55mm). Direct PCB placement compatibility is maintained without footprint modification.

Q: Do substitute parts maintain automotive qualification?

A: Yes. All substitute parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL Level 1 rating, matching the original ESR03EZPJ183 specifications.

Q: When should ERJ-PA3J183V be selected over ESR03EZPJ183?

A: ERJ-PA3J183V should be selected when circuit analysis indicates power dissipation exceeding 0.25W, when Panasonic sourcing is required for supply chain continuity, or when design specifications allow manufacturer substitution while maintaining identical electrical performance.
