Key Parameters

Substitute Part Grouping Explanation

Substitution of the 1N4734A_S00Z is determined by electrical and mechanical parameter equivalence. The critical parameters governing substitution are:

• Zener voltage (Vz): 5.6 V nominal
• Tolerance: ±5%
• Maximum power dissipation: 1 W
• Maximum impedance (Zzt): 5 Ohms
• Reverse leakage current: 10 µA @ 2 V
• Operating temperature range: -65°C to 200°C
• Mounting configuration: Through-hole axial package (DO-41 / DO-204AL)

The 1N4734A manufactured by Microsemi Corporation satisfies all electrical and mechanical requirements and is classified as an active product, providing continuity for applications currently using the obsolete 1N4734A_S00Z.

Parameter Comparison

Engineering Selection Recommendations

The 1N4734A manufactured by Microsemi Corporation is a direct functional equivalent to the obsolete 1N4734A_S00Z. Both components share identical electrical specifications, operating temperature ranges, and through-hole axial packaging. The Microsemi 1N4734A is currently in active production with substantial inventory availability (285,200 pcs), ensuring supply continuity.

Both parts are REACH Unaffected and classified under ECCN EAR99 and HTSUS 8541.10.0050. The Microsemi component is RoHS non-compliant, consistent with the through-hole Zener diode category. Selection of the Microsemi 1N4734A eliminates obsolescence risk while maintaining full electrical and mechanical compatibility with existing circuit designs.

Frequently Asked Questions (FAQ)

Q: Can the Microsemi 1N4734A directly replace the onsemi 1N4734A_S00Z in existing designs?

A: Yes. Both components have identical Zener voltage (5.6 V), tolerance (±5%), power rating (1 W), impedance (5 Ohms maximum), reverse leakage current (10 µA @ 2 V), operating temperature range (-65°C to 200°C), and through-hole axial packaging. No circuit modifications are required.

Q: What is the difference between DO-41 and DO-204AL packaging?

A: DO-41 and DO-204AL are equivalent designations for the same through-hole axial package used for Zener diodes. Both terms refer to the same physical form factor and pin configuration.

Q: Why is the onsemi 1N4734A_S00Z classified as obsolete?

A: Obsolescence status indicates the manufacturer has discontinued production. The Microsemi 1N4734A provides functional equivalence and active production status for continued component availability.

Q: Are there any compliance differences between the two parts?

A: Both components are REACH Unaffected and classified under the same ECCN and HTSUS codes. The Microsemi component is RoHS non-compliant, which is standard for through-hole Zener diodes in this category.

Q: What inventory levels are available for the substitute part?

A: The Microsemi 1N4734A has 285,200 pcs in stock, providing substantial availability compared to the 713 pcs remaining for the obsolete onsemi part.
