Substitute Part Grouping Explanation

Substitution of the 2N5484_D74Z is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Technology: JFET (N-Channel configuration)
• Frequency: 400MHz operational capability
• Voltage - Test: 15V
• Voltage - Rated: 25V
• Current Rating: 5mA
• Noise Figure: 4dB

Mechanical Compatibility Criteria:

• Package type and pin configuration must support the application's mounting requirements

The MMBF5484 substitute part maintains identical electrical specifications to the 2N5484_D74Z. The primary difference is the package format: MMBF5484 uses a surface-mount SOT-23-3 package instead of the through-hole TO-92-3 package of the original part. This substitution is valid when the application circuit board supports surface-mount technology.

Engineering Selection Recommendations

For Direct Through-Hole Replacement: No direct through-hole substitute with identical package configuration is available. The 2N5484_D74Z remains the only TO-92-3 packaged option for this specification set, though it is obsolete.

For Surface-Mount Redesign: The MMBF5484 is the appropriate substitute when circuit board redesign to surface-mount technology is feasible. This part is manufactured by onsemi, the same original equipment manufacturer, and maintains all electrical specifications of the 2N5484_D74Z. The MMBF5484 is classified as active product status, ensuring ongoing availability and supply chain support.

Compliance Considerations: Both the 2N5484_D74Z and MMBF5484 are REACH Unaffected and classified under ECCN EAR99. The MMBF5484 carries RoHS3 Compliance certification, providing additional environmental and regulatory alignment for new designs.

Frequently Asked Questions (FAQ)

Q: Can the MMBF5484 be used as a direct replacement for the 2N5484_D74Z in existing through-hole circuit boards?

A: No. The MMBF5484 uses a surface-mount SOT-23-3 package, while the 2N5484_D74Z uses a through-hole TO-92-3 package. Direct substitution on existing through-hole PCBs is not possible without circuit board modification or the use of surface-mount to through-hole adapter components.

Q: Are the electrical characteristics identical between the 2N5484_D74Z and MMBF5484?

A: Yes. Both devices share identical specifications for technology (JFET N-Channel), frequency (400MHz), test voltage (15V), rated voltage (25V), current rating (5mA), and noise figure (4dB).

Q: Why is the 2N5484_D74Z classified as obsolete?

A: The 2N5484_D74Z is an older through-hole packaged component. onsemi has transitioned this product line to surface-mount technology, represented by the MMBF5484 in the SOT-23-3 package, which is the active product variant.

Q: What is the moisture sensitivity level for both parts?

A: Both the 2N5484_D74Z and MMBF5484 have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage or handling.

Q: Are there any regulatory or compliance differences between these parts?

A: Both parts are REACH Unaffected and classified as EAR99. The MMBF5484 additionally carries RoHS3 Compliance certification, making it suitable for applications with environmental compliance requirements.

Q: What inventory status should be considered when selecting between these parts?

A: The 2N5484_D74Z has 769 pieces in stock as new original inventory. The MMBF5484 has 19,275 pieces in stock. For long-term supply chain planning, the MMBF5484 offers greater availability as an active product.
