Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the ESR03EZPJ2R7 is determined by the following critical parameters:

• Resistance Value: Must be 2.7 Ohms
• Package Type: Must be 0603 (1608 Metric)
• Composition: Thick film construction
• Automotive Compliance: AEC-Q200 qualification required
• Operating Temperature Range: -55°C to 155°C minimum
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity: MSL 1 or better

Tolerance and power rating variations are permitted when the application circuit design accommodates the electrical differences. Tolerance upgrades (±5% to ±1%) and power rating increases (0.25W to 0.333W) represent functional improvements and are considered direct upgrades.

Parameter Comparison

Engineering Selection Recommendations

ESR03EZPF2R70 (Rohm Semiconductor): This upgrade substitute offers improved tolerance specification (±1% versus ±5%) while maintaining identical power rating, package, and thermal characteristics. Selection is appropriate for applications requiring tighter resistance accuracy. Both parts are manufactured by Rohm Semiconductor, ensuring consistent thick film construction and AEC-Q200 compliance.

ERJ-PA3J2R7V (Panasonic Electronic Components): This direct substitute provides a higher power rating (0.333W versus 0.25W) in the same 0603 package with matching tolerance and temperature specifications. The increased power dissipation capability makes this suitable for applications with higher current demands. Full AEC-Q200 and ROHS3 compliance is maintained.

ERJ-3BQJ2R7V (Panasonic Electronic Components): This similar substitute matches the electrical specifications and power rating of the main part while offering an alternative manufacturer source. The part is specified for current sense applications and maintains all automotive and compliance requirements. Selection provides supply chain diversification.

All substitute parts maintain active product status, identical operating temperature ranges, and equivalent moisture sensitivity ratings.

Frequently Asked Questions (FAQ)

Q: Can ESR03EZPF2R70 be used as a direct replacement for ESR03EZPJ2R7?
