Substitute Part Grouping Explanation

Substitution eligibility for the MNR04MRAPJ821 is determined by strict equivalence across the following critical parameters:

• Resistance value: 820 Ohms
• Tolerance: ±5%
• Number of resistors: 4
• Circuit type: Isolated
• Power per element: 62.5mW
• Temperature coefficient: ±200ppm/°C
• Number of pins: 8
• Package configuration: 0804, Convex, Long Side Terminals
• Mounting type: Surface Mount
• RoHS compliance: ROHS3 Compliant
• Moisture sensitivity level: 1 (Unlimited)

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

Parameter Comparison

Engineering Selection Recommendations

The EXB-28V821JX is a direct functional equivalent to the MNR04MRAPJ821. Both components share identical electrical specifications, package dimensions, and compliance certifications (ROHS3, REACH Unaffected, EAR99).

The EXB-28V821JX is currently in active production status with substantial inventory availability (30,622 pcs), making it the appropriate choice for applications requiring the MNR04MRAPJ821. The Panasonic component includes automotive AEC-Q200 qualification, providing additional reliability assurance for demanding applications.

The maximum seated height of the EXB-28V821JX is 0.018" (0.45mm) compared to 0.020" (0.50mm) for the original part. This 0.002" difference is within typical PCB assembly tolerances and does not affect functional compatibility.

The operating temperature range of the EXB-28V821JX extends to -55°C ~ 125°C, which covers the lower end of the MNR04MRAPJ821 range (-55°C ~ 155°C). For applications requiring operation above 125°C, the original specification must be verified against actual system requirements.

Frequently Asked Questions (FAQ)

Q: Can the EXB-28V821JX be used as a direct replacement for the MNR04MRAPJ821 in existing designs?

A: Yes. The EXB-28V821JX meets all electrical and mechanical specifications of the MNR04MRAPJ821, including resistance value, tolerance, power rating, temperature coefficient, pin count, and package configuration. No design modifications are required for PCB layout or schematic.

Q: What is the significance of the height difference between these components?

A: The EXB-28V821JX has a maximum seated height of 0.018" (0.45mm) versus 0.020" (0.50mm) for the MNR04MRAPJ821. This 0.002" (0.05mm) difference is negligible for standard surface mount assembly processes and does not affect component placement, solder reflow, or functional performance.

Q: Are there any temperature range limitations when substituting the EXB-28V821JX?

A: The EXB-28V821JX operates from -55°C to 125°C, while the MNR04MRAPJ821 operates to 155°C. For applications requiring sustained operation above 125°C, the upper temperature capability of the original part must be confirmed as a system requirement before substitution.

Q: Do both components meet the same compliance standards?

A: Yes. Both the MNR04MRAPJ821 and EXB-28V821JX are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What packaging options are available for the EXB-28V821JX?

A: The EXB-28V821JX is supplied in Tape & Reel (TR) packaging, which is standard for high-volume surface mount production. The component dimensions and pin configuration remain identical to the original part.
