Key Parameters

Substitute Part Grouping Explanation

Substitution of the TISP7380F3SL is determined by electrical parameter equivalence across the following critical specifications:

• Voltage - Breakover: 380V
• Voltage - Off State: 270V
• Voltage - On State: 5V
• Current - Peak Pulse (8/20µs): 175A
• Current - Peak Pulse (10/1000µs): 45A
• Current - Hold (Ih): 150mA
• Number of Elements: 3
• Capacitance: 39pF
• Base Product Number: TISP73

The TISP7380F3DR-S maintains identical electrical characteristics and element configuration, qualifying it as a direct functional equivalent. The primary distinction lies in packaging format and product status, with the substitute available in surface-mount 8-SOIC configuration versus the original through-hole 3-SIP package.

Parameter Comparison

Engineering Selection Recommendations

The TISP7380F3DR-S is the direct electrical equivalent for the obsolete TISP7380F3SL. Selection between these parts is determined by circuit board design requirements and regulatory compliance needs.

The TISP7380F3DR-S offers the advantage of active product status, ensuring long-term availability and supply chain continuity. This part also meets ROHS3 compliance requirements, whereas the original TISP7380F3SL is RoHS non-compliant. Both parts maintain identical electrical performance across all specified parameters.

The primary consideration is mounting technology: the original part uses through-hole 3-SIP packaging, while the substitute employs surface-mount 8-SOIC packaging. This difference requires PCB layout modification and assembly process adjustment. Circuit board redesign is necessary to accommodate the alternative package format.

Frequently Asked Questions (FAQ)

Q: Are the TISP7380F3SL and TISP7380F3DR-S electrically identical?

A: Yes. Both parts share identical electrical specifications including breakover voltage (380V), off-state voltage (270V), on-state voltage (5V), peak pulse current (175A at 8/20µs), hold current (150mA), and capacitance (39pF).

Q: What is the primary difference between these parts?

A: The TISP7380F3SL uses through-hole 3-SIP packaging for through-hole PCB assembly. The TISP7380F3DR-S uses surface-mount 8-SOIC packaging for surface-mount PCB assembly. The substitute also carries active product status and ROHS3 compliance versus the obsolete, RoHS non-compliant original.

Q: Can I use the TISP7380F3DR-S as a direct replacement without PCB modification?

A: No. The different package formats (3-SIP through-hole versus 8-SOIC surface-mount) require PCB layout redesign and assembly process changes. Footprint, pad configuration, and mounting method are incompatible between these packages.

Q: Why is the TISP7380F3SL classified as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The TISP7380F3DR-S represents the active product line continuation with equivalent electrical performance.

Q: Are there compliance differences between these parts?

A: Yes. The TISP7380F3DR-S meets ROHS3 compliance requirements, while the TISP7380F3SL is RoHS non-compliant. Both parts maintain identical REACH and ECCN classifications.
