Substitute Part Grouping Explanation

Substitution of the VLS201610CX-1R5M with VLS201610CX-1R5M-1 is based on electrical and mechanical parameter equivalence. The key parameters that govern substitution are:

• Inductance Value: Both parts maintain 1.5 µH ±20% tolerance
• Current Rating: Both rated for 1.74 A continuous current
• Saturation Current (Isat): Identical at 1.58 A
• DC Resistance: Both specify 126mOhm maximum DCR
• Core Material & Shielding: Ferrite core with shielding in both parts
• Operating Temperature Range: -40°C to 105°C for both
• Physical Dimensions: Identical footprint of 2.00mm x 1.60mm with 1.00mm maximum height
• Mounting Type: Surface mount for both parts
• Compliance: Both ROHS3 compliant with MSL 1

The substitute part differs only in packaging configuration (Tape & Reel vs. bulk) and product status (Active vs. Obsolete), with no electrical or mechanical parameter changes.

Parameter Comparison

Engineering Selection Recommendations

The VLS201610CX-1R5M-1 provides full electrical and mechanical substitution for the obsolete VLS201610CX-1R5M. Selection of the substitute part is appropriate for new designs and production where the obsolete part is no longer available. Both parts maintain ROHS3 compliance and identical MSL 1 rating, ensuring regulatory alignment and identical moisture handling requirements.

The active product status of VLS201610CX-1R5M-1 ensures continued availability and manufacturing support. The primary distinction lies in packaging format: the substitute is supplied in Tape & Reel configuration, whereas the main part is supplied in bulk. This difference does not affect electrical performance or board-level compatibility for surface mount assembly.

Frequently Asked Questions (FAQ)
