ESR01MZPJ301 Equivalent & Substitute Parts

Part Overview

The ESR01MZPJ301 is a 300 Ohm ±5% thick film chip resistor manufactured by Rohm Semiconductor, rated for 0.2W (1/5W) power dissipation in a 0402 (1005 Metric) surface mount package. This component is designed for automotive applications and meets AEC-Q200 qualification standards with pulse withstanding capability. The part is currently active in production with 837 pieces available in inventory. Equivalent and substitute parts are identified when designs require alternative sourcing, inventory replenishment, or manufacturer-specific procurement strategies while maintaining identical electrical and mechanical performance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESR01MZPJ301 is determined by strict equivalence across the following critical parameters: resistance value (300 Ohms), tolerance (±5%), package type (0402 / 1005 Metric), composition (thick film), temperature coefficient (±200ppm/°C), operating temperature range (-55°C ~ 155°C), automotive qualification (AEC-Q200), and compliance certifications (ROHS3, REACH Unaffected, EAR99).

The identified substitute parts maintain these core specifications. One substitute, ERJ-PA2J301X, differs in power rating (0.25W / 1/4W versus 0.2W / 1/5W) but remains functionally compatible for applications where the higher power rating does not create design constraints. All substitutes are manufactured by established automotive-qualified suppliers and carry identical environmental and regulatory compliance status.

Parameter Comparison

Engineering Selection Recommendations

All identified substitute parts maintain full compliance with AEC-Q200 automotive qualification and ROHS3 environmental standards. Selection between the ESR01MZPJ301 and its substitutes should be based on procurement availability and supply chain requirements.

CRCW0402300RJNEDHP and RCS0402300RJNED are direct electrical and mechanical equivalents with identical power ratings (0.2W). These parts are interchangeable without design modification.

ERJ-PA2J301X offers a higher power rating (0.25W versus 0.2W) while maintaining all other specifications. This part is suitable for applications where increased power dissipation margin is acceptable or beneficial. The higher power rating does not create incompatibility with designs specified for 0.2W operation.

Frequently Asked Questions (FAQ)

Q: Can CRCW0402300RJNEDHP be used as a direct replacement for ESR01MZPJ301?

A: Yes. Both parts share identical resistance (300 Ohms), tolerance (±5%), power rating (0.2W), package (0402), temperature coefficient (±200ppm/°C), operating range (-55°C ~ 155°C), and AEC-Q200 qualification. No design changes are required.

Q: What is the difference between ERJ-PA2J301X and the other substitutes?

A: ERJ-PA2J301X has a higher power rating of 0.25W (1/4W) compared to 0.2W (1/5W) for the other parts. All other electrical and mechanical parameters are identical. The higher power rating provides additional thermal margin in applications.

Q: Are all substitute parts automotive-qualified?

A: Yes. All listed substitute parts carry AEC-Q200 qualification and are suitable for automotive applications requiring this certification.

Q: Do the substitute parts have the same package dimensions?

A: Yes. All parts use the 0402 (1005 Metric) package with identical footprint dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm).

Q: Are there any compliance or regulatory differences between these parts?

A: No. All parts are ROHS3 compliant, REACH unaffected, and classified as EAR99. Moisture sensitivity level is 1 (Unlimited) for all parts.

Q: Which substitute has the highest inventory availability?

A: RCS0402300RJNED from Vishay Dale has the highest inventory with 49,078 pieces available, followed by CRCW0402300RJNEDHP with 11,150 pieces and ERJ-PA2J301X with 10,001 pieces.
