ESR01MZPJ681 Equivalent & Substitute Parts

Part Overview

The ESR01MZPJ681 is a 680 Ohm ±5% thick film chip resistor manufactured by Rohm Semiconductor in 0402 (1005 Metric) package format. Rated for 0.2W (1/5W) power dissipation, this component is designed for automotive applications and meets AEC-Q200 qualification standards with pulse withstanding capability. The part is currently in active production status with 1130 units available in inventory.

Equivalent and substitute parts are identified when component availability is limited, supply chain disruptions occur, or design flexibility is required while maintaining electrical and mechanical compatibility within automotive-grade specifications.

Substitute Part Grouping Explanation

Substitution eligibility for the ESR01MZPJ681 is determined by strict equivalence across the following critical parameters:

• Resistance value: 680 Ohms
• Tolerance: ±5%
• Package format: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature coefficient: ±200ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity: MSL 1

Power rating represents the only parameter where substitutes may exceed the original specification. A substitute with equal or higher power rating (0.2W or greater) maintains full compatibility and may provide additional design margin in thermal management scenarios.

Parameter Comparison

Engineering Selection Recommendations

All three parts—ESR01MZPJ681, CRCW0402680RJNEDHP, and ERJ-PA2J681X—are functionally equivalent for automotive applications requiring 680 Ohm ±5% thick film resistors in 0402 package format. Each part maintains active production status, full AEC-Q200 compliance, and ROHS3 certification.

The CRCW0402680RJNEDHP (Vishay Dale) provides direct electrical and thermal equivalence with identical 0.2W power rating. The ERJ-PA2J681X (Panasonic) offers increased power handling at 0.25W (1/4W), providing additional thermal margin in applications where power dissipation approaches component limits.

Selection between these parts should be based on supply availability, lead time requirements, and established supplier relationships within your procurement workflow.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PA2J681X replace ESR01MZPJ681 in all applications?

A: Yes. The ERJ-PA2J681X is electrically and mechanically compatible. The higher power rating (0.25W vs. 0.2W) does not create incompatibility; it provides additional thermal capacity. Physical dimensions, resistance value, tolerance, temperature coefficient, and operating range are identical across all three parts.

Q: Are there any package or footprint differences between these substitutes?

A: No. All three parts use the 0402 (1005 Metric) package format with identical physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) and maximum seated height of 0.016" (0.40mm). PCB footprints are interchangeable.

Q: Do all substitutes meet automotive qualification requirements?

A: Yes. ESR01MZPJ681, CRCW0402680RJNEDHP, and ERJ-PA2J681X all carry AEC-Q200 qualification and are suitable for automotive applications requiring pulse withstanding thick film resistors.

Q: What is the significance of MSL 1 rating?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture bake-out requirements. All three parts share this rating, eliminating moisture-related handling constraints during storage and assembly.

Q: Are there compliance or certification differences?

A: No. All parts are ROHS3 compliant, REACH unaffected, and classified under identical ECCN (EAR99) and HTSUS (8533.21.0030) codes.
