Substitute Part Grouping Explanation

Substitute parts for the ESR01MZPJ821 are qualified based on the following criteria:

Primary Substitution Parameters:

• Resistance value: 820 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

Two substitute parts meet these criteria with full electrical and mechanical compatibility. Both maintain identical resistance, tolerance, package dimensions, thermal characteristics, and automotive compliance ratings. The substitutes differ only in manufacturer identity and power rating specification, with one part rated at 0.25W (1/4W) instead of 0.2W (1/5W).

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts are suitable for direct replacement of the ESR01MZPJ821 in automotive applications. All three parts maintain active production status and carry identical AEC-Q200 automotive qualification and ROHS3 compliance certifications.

The CRCW0402820RJNEDHP (Vishay Dale) provides exact electrical and power rating equivalence with the original part, maintaining 0.2W (1/5W) specification across all parameters.

The ERJ-PA2J821X (Panasonic Electronic Components) offers higher power rating capability at 0.25W (1/4W) while maintaining all other electrical and mechanical specifications. This part is suitable for applications where additional thermal margin is beneficial, provided circuit design accommodates the slightly higher power dissipation capability.

Selection between substitutes should be based on manufacturer availability, supply chain requirements, and design margin preferences. All three parts are functionally interchangeable within the specified electrical and thermal operating parameters.

Frequently Asked Questions (FAQ)

Q: Can the ERJ-PA2J821X (0.25W) be used in place of the ESR01MZPJ821 (0.2W)?

A: Yes. The ERJ-PA2J821X maintains identical resistance, tolerance, package dimensions, temperature coefficient, and operating temperature range. The higher power rating (0.25W vs 0.2W) does not create compatibility issues; it provides additional thermal margin. All other electrical and mechanical parameters are equivalent.

Q: Are all three parts mechanically identical?

A: Yes. All three parts share identical 0402 (1005 Metric) package dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm) with maximum seated height of 0.016" (0.40mm). They are footprint-compatible and require no PCB layout modifications.

Q: Do all substitute parts meet automotive qualification requirements?

A: Yes. All three parts carry AEC-Q200 automotive qualification rating and ROHS3 compliance certification. They are suitable for automotive circuit applications without additional qualification requirements.

Q: What is the significance of the ±200ppm/°C temperature coefficient?

A: The temperature coefficient specifies resistance change per degree Celsius across the operating temperature range of -55°C to 155°C. All three parts share identical ±200ppm/°C specification, ensuring equivalent thermal stability and predictable resistance variation under temperature extremes.

Q: Are moisture sensitivity considerations identical across all three parts?

A: Yes. All three parts carry Moisture Sensitivity Level (MSL) rating of 1 (Unlimited), indicating no moisture-related storage or handling restrictions. Standard component storage practices apply equally to all three parts.
