1N5340B-TP Equivalent & Substitute Parts

Part Overview

The 1N5340B-TP is a Zener diode manufactured by Micro Commercial Co, rated for 6 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 maintains Active product status and is ROHS3 compliant.

Substitute parts are identified when electrical specifications, mechanical compatibility, and regulatory compliance align with the main part's operational requirements. Alternative sources and packaging formats may be necessary due to inventory availability, supply chain considerations, or specific application packaging requirements.

Engineering Selection Recommendations

All three parts maintain Active product status and satisfy ROHS3 and REACH compliance requirements, confirming regulatory equivalence for applications requiring these certifications.

1N5340BG (onsemi, Bulk Packaging): This substitute provides identical electrical specifications and extended operating temperature range (-65°C to 200°C). The Bulk packaging format suits high-volume procurement scenarios. This part is suitable for applications where the extended temperature range provides operational margin beyond the main part's -55°C to 150°C specification.

1N5340BRLG (onsemi, Cut Tape Packaging): This substitute matches the Cut Tape packaging format of the main part, facilitating direct integration into existing assembly processes. Electrical specifications and extended operating temperature range (-65°C to 200°C) are identical to the 1N5340BG variant. This part is suitable for applications requiring tape-and-reel format compatibility with existing pick-and-place equipment.

Both onsemi substitutes are electrically and mechanically compatible with the 1N5340B-TP. Selection between them depends on packaging format requirements and procurement volume considerations.

Frequently Asked Questions (FAQ)

Q: Can 1N5340BG and 1N5340BRLG be used interchangeably with 1N5340B-TP?

A: Yes. All three parts share identical electrical specifications: 6 V nominal Zener voltage, ±5% tolerance, 5 W maximum power, 1 Ohm maximum impedance, and matching forward voltage characteristics. All are through-hole axial components with Active product status and ROHS3 compliance.

Q: What is the difference between 1N5340BG and 1N5340BRLG?

A: The primary difference is packaging format. 1N5340BG is supplied in Bulk packaging, while 1N5340BRLG is supplied in Cut Tape (CT) format. Both parts are manufactured by onsemi and possess identical electrical specifications and extended operating temperature range (-65°C to 200°C).

Q: Does the extended operating temperature range of the onsemi substitutes affect compatibility?

A: No. The extended range (-65°C to 200°C for onsemi parts versus -55°C to 150°C for the main part) represents an operational superset. Applications operating within the main part's temperature specification remain fully compatible with either substitute.

Q: Are there packaging considerations when substituting these parts?

A: Yes. The main part 1N5340B-TP uses DO-15 packaging format. The onsemi substitutes use T-18 Axial packaging. Both are through-hole axial components with compatible mechanical footprints for standard PCB layouts. Verify PCB pad spacing and component lead dimensions for your specific application.

Q: Do all three parts meet the same regulatory requirements?

A: Yes. All three parts are ROHS3 compliant and REACH unaffected, satisfying identical regulatory compliance requirements.

Q: Which substitute should be selected for new designs?

A: Selection depends on packaging requirements. For tape-and-reel assembly processes, use 1N5340BRLG. For bulk procurement or manual assembly, use 1N5340BG. Both provide identical electrical performance and extended temperature range operational margin.
