Substitute Part Grouping Explanation

Substitution of the TISP7150F3DR is determined by electrical and mechanical parameter equivalence. The following criteria establish valid substitution:

Electrical Parameters (Critical):

• Voltage - Breakover: 150V
• Voltage - Off State: 120V
• 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: 47pF

Mechanical Parameters (Critical):

• Package / Case: 8-SOIC (0.154", 3.90mm Width)
• Mounting Type: Surface Mount

The TISP7150F3DR-S meets all electrical and mechanical equivalence criteria and is identified as a direct substitute.

Parameter Comparison

Engineering Selection Recommendations

The TISP7150F3DR-S is a direct electrical and mechanical equivalent to the TISP7150F3DR. The primary distinction is product status and regulatory compliance.

The TISP7150F3DR is obsolete and RoHS non-compliant. The TISP7150F3DR-S is active and ROHS3 compliant, making it the preferred selection for new designs and ongoing production where regulatory compliance is required.

Both parts share identical electrical performance parameters, package specifications, and environmental ratings. Selection between these parts should be based on supply chain availability, regulatory requirements of the end application, and design timeline constraints.

Frequently Asked Questions (FAQ)

Q: Can TISP7150F3DR-S replace TISP7150F3DR in existing designs?
