Key Parameters

Substitute Part Grouping Explanation

Substitution of the J112_D11Z is determined by matching the following critical electrical and mechanical parameters:

• N-Channel FET type configuration
• Voltage - Breakdown (V(BR)GSS) of 35 V
• Current - Drain (Idss) @ Vds of 5 mA @ 15 V
• Voltage - Cutoff (VGS off) @ Id of 1 V @ 1 µA
• Resistance - RDS(On) of 50 Ohms
• Power - Max rating of 625 mW
• Operating Temperature range of -55°C to 150°C (TJ)
• Through-hole mounting in TO-92-3 package

The J112 (bulk packaging variant) meets all electrical specifications and mechanical requirements, establishing it as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The J112 is the direct substitute for the J112_D11Z. Both parts are manufactured by onsemi and share identical electrical and mechanical specifications. The primary distinction is product status: J112_D11Z is obsolete while J112 maintains active production status. The J112 is ROHS3 compliant and carries REACH Unaffected certification, meeting current regulatory requirements. Inventory availability of the J112 (18,472 pcs) provides supply continuity for applications currently using the J112_D11Z. Pin configuration, package footprint, and electrical performance are fully compatible for direct substitution in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can J112 replace J112_D11Z in existing designs? A: Yes. Both parts are electrically and mechanically identical. The J112 is the active production equivalent of the obsolete J112_D11Z.

Q: Are there differences in packaging between these parts? A: Both use TO-92-3 (TO-226AA) through-hole packaging with formed leads. No package modifications are required.

Q: What is the difference between J112_D11Z and J112? A: The J112_D11Z is supplied in tape and reel packaging (indicated by the _D11Z suffix), while J112 is supplied in bulk packaging. Electrical specifications are identical.

Q: Does the J112 meet current compliance standards? A: Yes. The J112 is ROHS3 compliant and REACH Unaffected, meeting current regulatory requirements for electronic components.

Q: Are there any thermal or operating condition differences? A: No. Both parts operate across the identical temperature range of -55°C to 150°C (TJ) and share all electrical ratings.

Q: What inventory status should be considered for procurement? A: The J112_D11Z is obsolete with limited stock (850 pcs). The J112 is in active production with substantial inventory (18,472 pcs), providing reliable supply for new designs and production runs.
