Substitute Part Grouping Explanation

Substitution eligibility for the ESR01MZPJ240 is determined by strict equivalence across the following critical parameters:

• Resistance value: 24 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 and environmental compliance status

The ERJ-PA2J240X from Panasonic Electronic Components meets all substitution criteria. While the power rating differs (0.25W versus 0.2W), this represents a higher capability rating that maintains full compatibility in applications designed for the original 0.2W specification.

Parameter Comparison

Engineering Selection Recommendations

Both the ESR01MZPJ240 and ERJ-PA2J240X are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts should be based on availability and supply chain requirements. The ERJ-PA2J240X offers a higher power rating (0.25W versus 0.2W) while maintaining identical electrical characteristics, package dimensions, and environmental specifications. This higher power capability provides additional thermal margin in applications operating at or near the original design power dissipation limits. Both components are suitable for direct substitution in automotive and industrial applications requiring 24 Ohm thick film resistors in 0402 package format.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PA2J240X replace ESR01MZPJ240 in existing designs?

A: Yes. The ERJ-PA2J240X is a direct substitute. Both parts share identical resistance, tolerance, package dimensions, temperature coefficient, and operating temperature range. The higher power rating of the Panasonic part (0.25W versus 0.2W) is fully compatible with applications designed for the original 0.2W specification.

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

A: No. Both components use the 0402 (1005 Metric) package with identical physical dimensions of 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 both parts meet automotive qualification requirements?

A: Yes. Both ESR01MZPJ240 and ERJ-PA2J240X carry AEC-Q200 qualification and are suitable for automotive applications. Both are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: What is the significance of the different power ratings?

A: The ERJ-PA2J240X is rated for 0.25W (1/4W) compared to the ESR01MZPJ240 at 0.2W (1/5W). This means the Panasonic part can dissipate more power without exceeding temperature limits. In applications using the original 0.2W specification, the higher-rated part provides additional thermal headroom and is fully compatible.

Q: Are the temperature coefficients identical?

A: Yes. Both parts have a temperature coefficient of ±200ppm/°C and operate across the same temperature range of -55°C to 155°C.
