Substitute Part Grouping Explanation

Substitution eligibility for the MNR04MRAPJ430 is determined by strict equivalence across the following critical parameters:

• Resistance value: 43 Ohm (exact match required)
• Tolerance: ±5% (exact match required)
• Circuit configuration: Isolated 4-resistor network (exact match required)
• Package / Case: 0804, Convex, Long Side Terminals (exact match required)
• Number of pins: 8 (exact match required)
• Power per element: 62.5mW (exact match required)
• Temperature coefficient: ±200ppm/°C (exact match required)
• Mounting type: Surface Mount (exact match required)
• RoHS compliance: ROHS3 Compliant (required for regulatory alignment)

The EXB-28V430JX from Panasonic Electronic Components meets all substitution criteria and is classified as a direct equivalent.

Parameter Comparison

Engineering Selection Recommendations

The EXB-28V430JX is a direct functional equivalent to the MNR04MRAPJ430 across all critical electrical and mechanical parameters. The substitute part is currently in active production status, ensuring long-term availability and supply chain continuity. Both components maintain ROHS3 compliance and identical moisture sensitivity ratings, supporting equivalent environmental and regulatory requirements.

The operating temperature range of the EXB-28V430JX extends to -55°C minimum but is limited to 125°C maximum, compared to the MNR04MRAPJ430's 155°C upper limit. Applications requiring operation above 125°C must evaluate this thermal constraint against specific circuit requirements.

Frequently Asked Questions (FAQ)

Q: Can the EXB-28V430JX replace the MNR04MRAPJ430 in existing designs?

A: Yes. The EXB-28V430JX meets all electrical and mechanical specifications for direct substitution, including resistance value, tolerance, circuit isolation, power rating, temperature coefficient, and package configuration. Pin count and terminal arrangement are identical.

Q: What is the primary difference between these two parts?

A: The operating temperature range differs. The MNR04MRAPJ430 operates from -55°C to 155°C, while the EXB-28V430JX operates from -55°C to 125°C. Applications operating above 125°C require the original Rohm part or alternative components rated for higher temperatures.

Q: Are both parts RoHS compliant?

A: Yes. Both the MNR04MRAPJ430 and EXB-28V430JX are ROHS3 compliant and carry identical moisture sensitivity ratings (MSL 1, Unlimited).

Q: What does the 0804 package designation indicate?

A: The 0804 package refers to the physical dimensions (0.079" L x 0.039" W / 2.00mm x 1.00mm) with convex, long side terminals for surface mount assembly. Both parts use identical package geometry and terminal configuration.

Q: Is the EXB-28V430JX suitable for automotive applications?

A: The EXB-28V430JX carries AEC-Q200 automotive qualification. Design requirements should confirm whether automotive-grade certification is necessary for the application.
