Substitute Part Grouping Explanation

Substitution eligibility for the MNR04M0ABJ821 is determined by strict alignment of the following parameters:

• Resistance value: 820 Ohms (exact match required)
• Tolerance: ±5% (exact match required)
• Number of resistors: 4 (exact match required)
• Circuit type: Isolated (exact match required)
• Power per element: 62.5mW (exact match required)
• Number of pins: 8 (exact match required)
• Package configuration: 0804, Convex, Long Side Terminals (exact match required)
• Mounting type: Surface Mount (exact match required)
• Operating temperature range: -55°C ~ 125°C (exact match required)
• RoHS compliance: ROHS3 Compliant (exact match required)

The EXB-28V821JX from Panasonic Electronic Components meets all substitution criteria and is classified as a direct equivalent.
