Substitute Part Grouping Explanation

Substitution of the VLS201610CX-150M is determined by strict equivalence across the following critical electrical and mechanical parameters:

Electrical Parameters:

• Inductance value: 15 µH with ±20% tolerance
• Current rating: 540 mA continuous
• Saturation current (Isat): 440 mA
• DC resistance: 1.258 Ohm maximum
• Inductance test frequency: 1 MHz

Mechanical & Physical Parameters:

• Core type: Ferrite drum core, wirewound construction
• Shielding: Shielded configuration
• Mounting type: Surface mount (SMD)
• Package footprint: 2-SMD compatible form factor
• Physical dimensions: 2.00 mm L × 1.60 mm W × 1.00 mm H (maximum seated height)

Environmental & Compliance:

• Operating temperature range: -40°C to 105°C
• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

The substitute part VLS201610CX-150M-1 meets all these criteria and is classified as a direct substitute based on identical electrical specifications and compatible mechanical packaging.

Parameter Comparison

Engineering Selection Recommendations

The VLS201610CX-150M has reached obsolete status within the manufacturer's product portfolio. The VLS201610CX-150M-1 serves as the direct active substitute, providing identical electrical performance and mechanical compatibility while maintaining current manufacturing availability.

Primary Consideration: VLS201610CX-150M-1 is the recommended substitute based on:

• Identical inductance value and tolerance specifications
• Matched current ratings and saturation characteristics
• Equivalent DC resistance performance
• Compatible physical footprint and mounting configuration
• Equivalent environmental operating range
• Maintained RoHS3 and MSL compliance standards

The shift from the main part's standard 2-SMD package to the substitute's tape & reel (TR) format with nonstandard package designation does not alter electrical or mechanical compatibility for board-level integration, provided component placement equipment and solder reflow processes remain within specified parameters.

Frequently Asked Questions (FAQ)

Q: Can VLS201610CX-150M-1 be directly substituted for VLS201610CX-150M in existing designs?

A: Yes. Both components share identical inductance values (15 µH ±20%), current ratings (540 mA), DC resistance specifications (1.258 Ohm max), and physical dimensions (2.00 mm × 1.60 mm × 1.00 mm max height). Direct substitution on PCB layouts is supported without modification.

Q: What is the key difference between the two part numbers?

A: The primary difference is product status and packaging format. VLS201610CX-150M is obsolete with 2-SMD packaging, while VLS201610CX-150M-1 is active with tape & reel (TR) format. The electrical and mechanical specifications remain equivalent.

Q: Are there compatibility concerns regarding the packaging format difference?

A: No. The nonstandard package designation on VLS201610CX-150M-1 reflects the tape & reel delivery format. The component footprint and land pattern remain identical to the original part. Standard SMD placement and reflow equipment processes both variants without modification.

Q: What compliance standards apply to both parts?

A: Both VLS201610CX-150M and VLS201610CX-150M-1 meet ROHS3 compliance requirements and carry MSL rating 1 (Unlimited moisture sensitivity). Both operate across the industrial temperature range of -40°C to 105°C.

Q: Should VLS201610CX-150M be replaced in active production?

A: Yes. Given the obsolete status of VLS201610CX-150M, design transition to VLS201610CX-150M-1 is recommended for ongoing production. The active status and current inventory availability of the substitute ensure supply chain continuity.
