Engineering Selection Recommendations

Primary Substitute: Würth Elektronik 824094024

The 824094024 is the recommended direct substitute for the obsolete 824098024. This selection is based on the following engineering factors:

Product Lifecycle Status: The 824094024 carries Active product status, ensuring continued availability, manufacturing support, and supply chain reliability. The 824098024 is classified as Obsolete, presenting long-term sourcing risk.

Electrical Equivalence: Both parts share identical breakdown voltage (26.2V minimum), peak pulse current rating (6A at 8/20µs), and operating temperature range (-55°C to 125°C). The clamping voltage variance of 1.5V (824094024 at 31V typical versus 824098024 at 32.5V typical) remains within acceptable tolerance for general-purpose transient suppression applications.

Mechanical and Compliance Compatibility: Both components utilize the SOT-23-3 surface-mount package, identical PCB footprint, and ROHS3 compliance certification. Moisture sensitivity levels are equivalent at MSL 3 (168 hours).

Packaging Availability: The 824094024 is available in Tape & Reel (TR) packaging format, supporting automated assembly processes and high-volume production environments.

The 824094024 provides direct functional replacement without circuit redesign or PCB layout modification.

Frequently Asked Questions (FAQ)

Q: Can the 824094024 be used as a direct drop-in replacement for the 824098024?

A: Yes. Both parts share identical SOT-23-3 package geometry, PCB footprint, and pin configuration. No circuit board modifications are required for substitution.

Q: What is the significance of the 1.5V difference in clamping voltage between these parts?

A: The 824098024 clamps at 32.5V typical, while the 824094024 clamps at 31V typical. For general-purpose overvoltage protection applications, this 1.5V variance remains within acceptable design margins and does not compromise transient suppression performance in standard 24V protection circuits.

Q: Are there any differences in thermal or electrical performance between these parts?

A: Both parts operate across the identical temperature range (-55°C to 125°C) and handle the same peak pulse current (6A at 8/20µs). Capacitance variance is 3pF, which is negligible for general-purpose TVS applications and does not affect circuit performance.

Q: Why is the 824098024 listed as Obsolete?

A: Product obsolescence reflects Würth Elektronik's lifecycle management. The 824094024 represents the active continuation of this TVS diode specification and is the recommended alternative for new designs and ongoing production.

Q: What packaging formats are available for the substitute part?

A: The 824094024 is supplied in Tape & Reel (TR) format, optimized for automated surface-mount assembly. This packaging supports high-volume manufacturing and reduces component handling costs.

Q: Are both parts RoHS compliant?

A: Yes. Both the 824098024 and 824094024 are ROHS3 compliant and meet current environmental and regulatory requirements for electronic component manufacturing and distribution.

Q: Can the 824094024 be used in applications originally designed for the 824098024?

A: Yes. The electrical specifications, package type, and operating parameters are equivalent. The part is suitable for all applications utilizing the 824098024 specification without circuit modification.
