SN75240PWG4 Equivalent & Substitute Parts

Part Overview

The SN75240PWG4 is a Transient Voltage Suppressor (TVS) device designed for circuit protection in USB applications. This mixed-technology TVS operates at a 7V clamping voltage and is housed in an 8-TSSOP surface mount package. The part is currently classified as Obsolete, making identification of equivalent and substitute parts essential for ongoing design support and procurement continuity. Substitute parts maintain identical electrical specifications and mechanical compatibility while offering improved availability or alternative product status classifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SN75240PWG4 is determined by strict equivalence across the following parameters:

• Voltage - Clamping: 7V (exact match required)
• Technology: Mixed Technology (exact match required)
• Number of Circuits: 1 (exact match required)
• Applications: USB (exact match required)
• Package / Case: 8-TSSOP (0.173", 4.40mm Width) (exact match required)
• RoHS Status: ROHS3 Compliant (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

All identified substitute parts meet these criteria. Differences in product status and packaging format (Cut Tape & Digi-Reel versus Tube) do not affect electrical or mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

For applications currently using the SN75240PWG4, the SN65240PWR is the preferred substitute due to its Active product status, ensuring long-term availability and manufacturing support. This part is supplied in Cut Tape and Digi-Reel formats, suitable for both manual and automated assembly processes.

The SN75240PW remains a valid alternative with identical electrical and mechanical specifications. However, its Last Time Buy status indicates limited future availability. This part is supplied in Tube packaging, appropriate for lower-volume or manual assembly operations.

Both substitute parts maintain full ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with current manufacturing and environmental standards.

Frequently Asked Questions (FAQ)

Q: Can SN65240PWR be used as a direct replacement for SN75240PWG4?

A: Yes. The SN65240PWR meets all electrical and mechanical requirements for direct substitution. Both parts operate at 7V clamping voltage, use mixed-technology design, and are housed in identical 8-TSSOP packages. The primary difference is product status (Active versus Obsolete) and packaging format (Cut Tape & Digi-Reel versus unspecified).

Q: What is the difference between SN75240PW and SN65240PWR?

A: Both parts are electrically and mechanically equivalent. The differences are: SN75240PW has Last Time Buy status with Tube packaging, while SN65240PWR has Active status with Cut Tape and Digi-Reel packaging. For new designs or long-term production, SN65240PWR is recommended.

Q: Are there any package compatibility concerns when substituting these parts?

A: No. All three parts use the 8-TSSOP package with identical dimensions (0.173" width, 4.40mm). PCB footprints and assembly processes remain unchanged during substitution.

Q: Do these parts require different handling or storage procedures?

A: No. All parts share Moisture Sensitivity Level 1 (Unlimited), indicating no special moisture control requirements during storage or handling.

Q: Which substitute should be selected for new production designs?

A: The SN65240PWR is recommended for new production designs due to its Active product status, ensuring continued manufacturing availability and technical support from Texas Instruments.
