Substitute Part Grouping Explanation

The 040AT1503SMLF is identified as a parametric equivalent to the 040AT1503SM based on strict electrical and mechanical compatibility. Both parts maintain identical specifications across all critical substitution parameters: inductance value (150 µH), tolerance (±10%), current rating (1.45 A), saturation current (1.4 A), DC resistance (190 mOhm Max), shielding configuration (Shielded), self-resonant frequency (4.6 MHz), operating temperature range (-55°C to 130°C), physical dimensions (0.565" L × 0.560" W), and seated height (0.360" Max).

The primary distinction between these parts is packaging format: the main part number 040AT1503SM is supplied in standard packaging, while 040AT1503SMLF is supplied in Tape & Reel (TR) format. This difference affects procurement and assembly processes but does not alter electrical or mechanical performance.

Parameter Comparison

Engineering Selection Recommendations

Both 040AT1503SM and 040AT1503SMLF are Active status components from Gowanda Electronics within the ATSM series. Selection between these parts is determined by packaging and compliance requirements rather than electrical performance.

The 040AT1503SM is suitable for applications where standard packaging is acceptable and RoHS compliance is not a requirement. The 040AT1503SMLF provides identical electrical and mechanical performance with Tape & Reel packaging format, which is preferred for automated assembly processes. Additionally, the 040AT1503SMLF carries ROHS3 Compliant certification, making it the appropriate choice for applications subject to RoHS regulations.

Both parts maintain identical inductance, current ratings, DC resistance, shielding characteristics, and thermal operating range, ensuring direct functional equivalence in circuit design and performance.

Frequently Asked Questions (FAQ)

Q: Can 040AT1503SMLF replace 040AT1503SM in existing designs?

A: Yes. Both parts are electrically and mechanically identical across all critical parameters including inductance (150 µH), current rating (1.45 A), DC resistance (190 mOhm Max), and physical dimensions. The difference is packaging format only.

Q: What is the primary difference between these two part numbers?

A: The 040AT1503SM is supplied in standard packaging, while 040AT1503SMLF is supplied in Tape & Reel (TR) format. Additionally, 040AT1503SMLF carries ROHS3 Compliant certification. Electrical and mechanical specifications are identical.

Q: Which part should be selected for automated assembly?

A: The 040AT1503SMLF with Tape & Reel packaging is optimized for automated pick-and-place assembly processes. The 040AT1503SM in standard packaging is suitable for manual or semi-automated assembly workflows.

Q: Are there any thermal or frequency performance differences?

A: No. Both parts operate across the identical temperature range (-55°C to 130°C) and maintain the same self-resonant frequency (4.6 MHz). Thermal and frequency characteristics are fully equivalent.

Q: Does RoHS compliance affect electrical performance?

A: No. ROHS3 compliance on the 040AT1503SMLF reflects material composition standards and does not alter electrical specifications, inductance value, current handling, or DC resistance characteristics.

Q: Can these parts be mixed in the same production batch?

A: Yes, provided assembly processes accommodate both packaging formats. Electrical and mechanical performance are identical, allowing interchangeable use in circuit applications.
