ESR01MZPF2002 Equivalent & Substitute Parts

Part Overview

The ESR01MZPF2002 is a 20 kOhms ±1% thick film chip resistor manufactured by Rohm Semiconductor in the 0402 (1005 Metric) package format. This component is rated for 0.2W (1/5W) power dissipation and meets AEC-Q200 automotive qualification standards with pulse withstanding capability. The part is currently active in production with 10,727 units in stock. Equivalent and substitute parts are identified when manufacturers discontinue production, when supply constraints occur, or when design flexibility allows for alternative qualified sources meeting identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESR01MZPF2002 is determined by strict equivalence across the following critical parameters:

• Resistance value: 20 kOhms
• Tolerance: ±1%
• Package format: 0402 (1005 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• Pulse withstanding capability
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

The three identified substitute parts meet all these criteria. One substitute (ERJ-PA2F2002X) differs in power rating (0.25W vs. 0.2W), which represents a higher capability and remains functionally compatible in applications designed for the 0.2W specification.

Parameter Comparison

Engineering Selection Recommendations

All four parts—ESR01MZPF2002, CRCW040220K0FKEDHP, ERJ-PA2F2002X, and RCS040220K0FKED—are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection among these parts is based on availability, packaging preference, and manufacturer sourcing strategy.

CRCW040220K0FKEDHP (Vishay Dale) offers the highest inventory availability at 87,612 units and maintains identical electrical and mechanical specifications to the primary part. RCS040220K0FKED (Vishay Dale) provides an alternative from the same manufacturer in Cut Tape and Digi-Reel® packaging formats, with 28,976 units available.

ERJ-PA2F2002X (Panasonic Electronic Components) provides a functionally compatible substitute with a higher power rating of 0.25W (1/4W) instead of 0.2W. This increased power capability does not compromise performance in circuits designed for the 0.2W specification and may offer improved thermal margin in power-dissipation-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PA2F2002X be used as a direct replacement for ESR01MZPF2002?

A: Yes. The ERJ-PA2F2002X meets all critical electrical parameters (20 kOhms, ±1% tolerance, ±100ppm/°C temperature coefficient, -55°C ~ 155°C operating range) and maintains identical package geometry (0402 / 1005 Metric). The higher power rating (0.25W vs. 0.2W) represents increased capability and does not create incompatibility in applications specified for 0.2W operation.

Q: What is the difference between Tape & Reel and Cut Tape packaging?

A: Tape & Reel (TR) packaging is supplied on continuous carrier tape wound on reels, suitable for high-volume automated assembly. Cut Tape (CT) and Digi-Reel® packaging provides smaller quantities on cut tape segments, appropriate for lower-volume production or prototype builds. Both formats contain identical components; packaging selection depends on production volume and assembly equipment compatibility.

Q: Are all substitute parts qualified for automotive applications?

A: Yes. All four parts carry AEC-Q200 automotive qualification, pulse withstanding capability, and ROHS3 compliance. They are suitable for automotive-grade circuit applications requiring these certifications.

Q: Can these parts be used interchangeably in the same PCB design?

A: Yes. All parts share identical footprint geometry (0402 / 1005 Metric), electrical specifications (20 kOhms ±1%), and operating characteristics. PCB layout and assembly processes require no modification when substituting among these parts.

Q: What does MSL 1 (Unlimited) mean?

A: Moisture Sensitivity Level 1 indicates the component has unlimited shelf life under standard storage conditions and requires no special moisture-control handling during storage, transportation, or assembly preparation.
