1N5368B-TP Equivalent & Substitute Parts

Part Overview

The 1N5368B-TP is an active zener diode manufactured by Micro Commercial Co, rated for 47 V nominal zener voltage with 5 W maximum power dissipation. This through-hole axial component operates across a temperature range of -55°C to 150°C and is packaged in DO-15 format. The part is ROHS3 compliant and maintains unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the zener voltage rating, power rating, tolerance, impedance, and leakage current parameters. Alternative sources and packaging formats may be required due to inventory availability, supply chain considerations, or specific application packaging requirements.

Substitute Part Grouping Explanation

Substitute parts for the 1N5368B-TP are qualified based on electrical parameter equivalence and mechanical compatibility. The following parameters determine substitution eligibility:

Electrical Equivalence Criteria:

Voltage - Zener (Nom): 47 V
Tolerance: ±5%
Power - Max: 5 W
Impedance (Max): 25 Ohms
Current - Reverse Leakage @ Vr: 500 nA @ 35.8 V
Voltage - Forward (Max) @ If: 1.2 V @ 1 A

Mechanical Compatibility Criteria:

Mounting Type: Through Hole
Package / Case: Axial configuration

The substitute parts 1N5368BG and 1N5368BRLG meet all electrical specifications and maintain through-hole axial mounting compatibility. Both are manufactured by onsemi and share the same base product number (1N5368), confirming functional equivalence. Differences in packaging format (Bulk versus Cut Tape) and operating temperature range extensions do not affect core substitution eligibility for applications within the 1N5368B-TP operating window.

Engineering Selection Recommendations

All three parts maintain active product status and full regulatory compliance under ROHS3 and REACH standards. The 1N5368B-TP, 1N5368BG, and 1N5368BRLG are electrically equivalent zener diodes with identical core specifications.

Selection between the main part and substitutes is determined by packaging and supply requirements:

1N5368B-TP is supplied by Micro Commercial Co in Cut Tape packaging with DO-15 package designation.

1N5368BG is supplied by onsemi in Bulk packaging with T-18 axial package designation and extended operating temperature range (-65°C to 200°C).

1N5368BRLG is supplied by onsemi in Cut Tape packaging with T-18 axial package designation and extended operating temperature range (-65°C to 200°C).

For applications operating within the 1N5368B-TP temperature specification (-55°C to 150°C), all three parts deliver equivalent performance. The onsemi alternatives provide extended temperature capability for applications requiring operation beyond the original part's limits. Packaging format selection (Cut Tape versus Bulk) aligns with procurement and assembly workflow requirements.

Frequently Asked Questions (FAQ)

Q: Can 1N5368BG and 1N5368BRLG be used interchangeably with 1N5368B-TP?

A: Yes. All three parts share identical electrical specifications: 47 V zener voltage, ±5% tolerance, 5 W power rating, 25 Ohms maximum impedance, and 500 nA reverse leakage current. All are through-hole axial mounted zener diodes with active product status and full regulatory compliance.

Q: What is the difference between 1N5368BG and 1N5368BRLG?

A: Both parts are manufactured by onsemi with identical electrical specifications and operating temperature range (-65°C to 200°C). The primary difference is packaging format: 1N5368BG is supplied in Bulk, while 1N5368BRLG is supplied in Cut Tape. The T-18 axial package designation is equivalent across both variants.

Q: Does the extended temperature range of onsemi parts affect substitution eligibility?

A: No. The extended operating temperature range (-65°C to 200°C) on onsemi parts does not restrict substitution. Applications operating within the 1N5368B-TP specification window (-55°C to 150°C) are fully compatible. The extended range represents additional capability, not a deviation from core electrical performance.

Q: Are there package compatibility considerations between DO-15 and T-18 axial formats?

A: Both DO-15 and T-18 are through-hole axial package formats with compatible lead spacing and mounting characteristics. Physical dimensions may vary slightly, but both are standard axial lead configurations suitable for through-hole PCB assembly and breadboard applications.

Q: What compliance certifications apply to all substitute parts?

A: All three parts are ROHS3 compliant and REACH unaffected. No additional compliance verification is required for substitution within equivalent electrical and mechanical parameters.
