Key Parameters

Substitute Part Grouping Explanation

Substitution of the J110_D26Z is determined by the following electrical and mechanical criteria:

Electrical Compatibility Requirements:

• FET Type: N-Channel (mandatory match)
• Voltage - Breakdown (V(BR)GSS): 25 V (must equal or exceed)
• Operating Temperature Range: -55°C to 150°C (must support or exceed)

Mechanical Compatibility Requirements:

• Mounting Type: Through Hole or Surface Mount (application-dependent)
• Package / Case: TO-92-3 (through hole) or equivalent surface mount alternatives

The MMBFJ108 qualifies as a substitute based on matching electrical specifications (N-Channel, 25 V breakdown, -55°C to 150°C operating range) while offering a surface mount alternative in SOT-23-3 packaging. This substitution is valid for applications where mounting type flexibility is acceptable.

Engineering Selection Recommendations

Product Status Consideration: The J110_D26Z is classified as obsolete. The MMBFJ108 is active and available in production quantities (1106 Pcs in stock), providing supply continuity for new designs and ongoing production support.

Compliance and Certification: Both devices are REACH Unaffected and classified under ECCN EAR99. The MMBFJ108 carries RoHS3 Compliant status, meeting modern environmental and regulatory requirements. Both devices have Moisture Sensitivity Level 1 (Unlimited).

Substitution Validity: The MMBFJ108 is electrically compatible as a substitute where the application tolerates surface mount packaging. The primary trade-off is mounting type: the J110_D26Z uses through-hole TO-92-3, while the MMBFJ108 uses surface mount SOT-23-3. Maximum power rating differs (625 mW vs. 350 mW), requiring verification that the MMBFJ108's lower power rating is acceptable for the intended application.

Frequently Asked Questions (FAQ)

Q: Can the MMBFJ108 directly replace the J110_D26Z on a through-hole PCB?

A: No. The J110_D26Z uses through-hole TO-92-3 packaging, while the MMBFJ108 uses surface mount SOT-23-3 packaging. PCB layout and assembly process modifications are required. Through-hole to surface mount conversion requires design changes.

Q: Are the electrical characteristics identical between these devices?

A: Both devices share the same N-Channel type, 25 V breakdown voltage, and -55°C to 150°C operating temperature range. However, drain current (Idss), cutoff voltage (VGS off), and on-resistance (RDS(On)) differ. The MMBFJ108 exhibits higher drain current and lower on-resistance, which may affect circuit performance depending on application requirements.

Q: What is the maximum power dissipation difference, and does it matter?

A: The J110_D26Z is rated for 625 mW maximum power, while the MMBFJ108 is rated for 350 mW. If the application requires power dissipation exceeding 350 mW, the MMBFJ108 is not suitable. Verify actual power dissipation in your circuit design.

Q: Are both devices compliant with current environmental regulations?

A: Both devices are REACH Unaffected. The MMBFJ108 is RoHS3 Compliant, meeting modern environmental standards. The J110_D26Z product status is obsolete, and RoHS compliance information is not provided.

Q: What is the inventory status for each device?

A: The J110_D26Z has 1052 Pcs in stock (obsolete status). The MMBFJ108 has 1106 Pcs in stock and is active, providing better long-term supply availability.
