TISP7380F3DR Equivalent & Substitute Parts

Part Overview

The TISP7380F3DR is a 270V off-state, 175A peak pulse thyristor-based transient voltage suppressor (TVS) in an 8-SOIC surface mount package manufactured by Bourns Inc. This component is designed for transient overvoltage protection in electronic circuits. The main part is currently listed as obsolete, making identification of suitable substitute components essential for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the TISP7380F3DR is based on electrical parameter equivalence and physical package compatibility. The critical parameters determining substitutability are:

• Voltage ratings (breakover, off-state, and on-state)
• Peak pulse current ratings (8/20µs and 10/1000µs)
• Hold current specification
• Number of internal elements
• Capacitance value
• Package type and physical dimensions

The TISP7380F3DR-S is a direct electrical and mechanical equivalent, differing only in packaging format (Tape & Reel versus bulk) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The TISP7380F3DR-S is a direct functional and mechanical substitute for the TISP7380F3DR. All electrical parameters are identical, and the 8-SOIC package dimensions are equivalent, ensuring PCB layout compatibility without modification.

The primary distinction is product lifecycle status: the TISP7380F3DR-S is currently in active production, whereas the original TISP7380F3DR is obsolete. Additionally, the TISP7380F3DR-S meets ROHS3 compliance requirements, whereas the original part is RoHS non-compliant. Both parts maintain identical REACH and ECCN classifications.

For new designs or component replenishment, the TISP7380F3DR-S is the appropriate selection due to its active status and regulatory compliance. Existing designs using the TISP7380F3DR can transition to the TISP7380F3DR-S without circuit or layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the TISP7380F3DR-S be used as a direct replacement for the TISP7380F3DR?

A: Yes. All electrical parameters, including voltage ratings, current ratings, and capacitance, are identical. The 8-SOIC package dimensions are equivalent, requiring no PCB layout changes.

Q: What is the difference between TISP7380F3DR and TISP7380F3DR-S?

A: The primary differences are packaging format (bulk versus Tape & Reel), product status (Obsolete versus Active), and RoHS compliance (non-compliant versus ROHS3 compliant). Electrical and mechanical specifications are identical.

Q: Is the TISP7380F3DR-S suitable for new designs?

A: Yes. The TISP7380F3DR-S is the recommended choice for new designs, as it is in active production and meets current RoHS3 compliance requirements.

Q: Are there any PCB layout considerations when substituting these parts?

A: No. Both parts use the identical 8-SOIC (0.154", 3.90mm Width) package, so existing PCB layouts require no modification.

Q: What certifications apply to both parts?

A: Both the TISP7380F3DR and TISP7380F3DR-S are classified as REACH Unaffected and carry an ECCN classification of EAR99. The TISP7380F3DR-S additionally meets ROHS3 compliance.
