Substitute Part Grouping Explanation

Substitution of the 2N5485_D26Z is determined by the following critical electrical and mechanical parameters:

Electrical Compatibility Criteria:

• Technology: JFET
• Configuration: N-Channel
• Frequency: 400MHz
• Voltage - Test: 15V
• Voltage - Rated: 25V
• Current Rating: 10mA
• Noise Figure: 4dB

Mechanical Compatibility Criteria:

• Mounting Type: Through Hole or Surface Mount (with PCB layout adaptation)
• Package / Case: TO-92-3 or equivalent surface-mount alternatives

The MMBF5485 qualifies as a direct electrical equivalent to the 2N5485_D26Z, sharing identical electrical specifications across all critical parameters. The primary difference is the package format: MMBF5485 uses a surface-mount SOT-23-3 package instead of the through-hole TO-92-3 package. This substitution requires PCB layout modification but maintains full electrical compatibility.

Engineering Selection Recommendations

Primary Substitute: MMBF5485

The MMBF5485 is the recommended substitute for the 2N5485_D26Z based on the following engineering criteria:

1. Electrical Equivalence: All critical electrical parameters match exactly, including frequency response (400MHz), voltage ratings (15V test, 25V rated), current rating (10mA), and noise figure (4dB).

2. Product Status: The MMBF5485 maintains active product status with onsemi, ensuring long-term availability and supply chain continuity. The 2N5485_D26Z is classified as obsolete.

3. Compliance: Both components share identical REACH and ECCN classifications (REACH Unaffected, EAR99), maintaining regulatory compliance across substitution.

4. Moisture Sensitivity: Both components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity constraints.

5. Package Consideration: The MMBF5485 uses SOT-23-3 surface-mount packaging instead of TO-92-3 through-hole packaging. This substitution requires PCB redesign for component placement and soldering methodology but does not affect electrical performance.

Frequently Asked Questions (FAQ)

Q: Can MMBF5485 be used as a direct pin-for-pin replacement for 2N5485_D26Z?

A: MMBF5485 provides electrical equivalence but not physical pin-for-pin compatibility. The 2N5485_D26Z uses through-hole TO-92-3 packaging, while MMBF5485 uses surface-mount SOT-23-3 packaging. PCB layout modification is required for substitution.

Q: Are the electrical specifications identical between 2N5485_D26Z and MMBF5485?

A: Yes. Both components share identical specifications for frequency (400MHz), voltage ratings (15V test, 25V rated), current rating (10mA), and noise figure (4dB). Both are N-Channel JFET devices manufactured by onsemi.

Q: Why is the 2N5485_D26Z classified as obsolete?

A: The 2N5485_D26Z is listed as obsolete by onsemi. The MMBF5485 represents the active product line continuation with equivalent electrical performance in a modern surface-mount package format.

Q: What are the compliance implications of substituting MMBF5485 for 2N5485_D26Z?

A: Both components carry identical REACH and ECCN classifications (REACH Unaffected, EAR99), ensuring no change in regulatory compliance status. Moisture sensitivity levels are also identical (MSL 1, Unlimited).

Q: Does package format affect circuit performance?

A: Package format does not affect electrical performance. The SOT-23-3 surface-mount package of MMBF5485 provides equivalent electrical characteristics to the TO-92-3 through-hole package of 2N5485_D26Z. PCB layout and assembly methodology differ, but circuit performance remains identical.

Q: What inventory status should be considered for procurement?

A: The 2N5485_D26Z shows 999 pieces in stock but is obsolete. The MMBF5485 shows 65,200 pieces in stock and maintains active product status, providing superior long-term availability and supply chain security.
