Substitute Part Grouping Explanation

Substitution of the TSM9409CS RLG is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following criteria:

Electrical Parameters (Must Match Exactly):

  • FET Type: P-Channel
  • Technology: MOSFET (Metal Oxide)
  • Drain to Source Voltage (Vdss): 60V
  • Continuous Drain Current (Id) @ 25°C: 3.5A (Ta)
  • Rds On (Max) @ 3.5A, 10V: 155mOhm
  • Gate Threshold Voltage (Vgs(th)) @ 250µA: 1V (Max)
  • Gate Charge (Qg) @ 10V: 6nC (Max)
  • Maximum Gate Voltage (Vgs): ±20V
  • Input Capacitance (Ciss) @ 30V: 540pF (Max)
  • Power Dissipation (Max): 3W (Ta)
  • Operating Temperature Range: -55°C to 150°C (TJ)

Mechanical Parameters (Must Match Exactly):

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

Compliance Parameters (Must Match Exactly):

  • RoHS Status: ROHS3 Compliant
  • REACH Status: REACH Unaffected

The substitute part TSM9409CS meets all these criteria and is therefore a direct parametric equivalent. The only difference between the main part and the substitute is the packaging format (Cut Tape versus Tape & Reel) and product status classification.

Frequently Asked Questions (FAQ)

Q: Can the TSM9409CS (Tape & Reel) be used as a direct replacement for the TSM9409CS RLG (Cut Tape)?

A: Yes. Both parts are electrically and mechanically identical. The only difference is the packaging format. Tape & Reel packaging is standard for high-volume manufacturing and automated assembly processes, while Cut Tape is used for lower-volume or manual assembly applications. The component itself functions identically in the circuit.

Q: What is the significance of the "Not For New Designs" status on the main part?

A: This classification indicates the TSM9409CS RLG has reached end-of-life status and the manufacturer no longer recommends its use in new product designs. The substitute part TSM9409CS carries an "Active" status, meaning it is currently manufactured and supported by Taiwan Semiconductor Corporation.

Q: Are the electrical parameters identical between the two parts?

A: Yes. All electrical parameters are identical, including Vdss (60V), continuous drain current (3.5A), Rds On (155mOhm @ 3.5A, 10V), gate threshold voltage (1V @ 250µA), gate charge (6nC @ 10V), and operating temperature range (-55°C to 150°C).

Q: Does the package size remain the same?

A: Yes. Both parts use the 8-SOIC package with 0.154" width (3.90mm). The physical footprint and pin configuration are identical, ensuring compatibility with existing PCB layouts and assembly equipment.

Q: Are there any compliance differences between the two parts?

A: No. Both parts maintain ROHS3 compliance and REACH unaffected status. There are no differences in regulatory or environmental compliance certifications.

Q: What is the difference between Cut Tape and Tape & Reel packaging?

A: Cut Tape (CT) packaging provides individual component strips cut to specific lengths, typically used for small-quantity orders or manual assembly. Tape & Reel (TR) packaging provides components on continuous tape wound on reels, optimized for high-speed automated assembly equipment. The components themselves are identical.

Q: Is the substitute part available in higher quantities?

A: Yes. The substitute part TSM9409CS (Tape & Reel) has 5870 pieces in stock, compared to 2109 pieces for the main part TSM9409CS RLG (Cut Tape). The higher inventory level reflects the active status and ongoing production of the substitute part.
