Substitute Part Grouping Explanation

Substitution of the DS1087LU-40K is determined by strict equivalence across the following electrical and mechanical parameters:

• Maximum frequency: 3.6864MHz
• Supply voltage range: 2.7V ~ 3.6V
• Operating temperature range: -40°C ~ 85°C
• Package type: 8-TSSOP/8-MSOP with 0.118" width and 3.00mm height
• Input/Output configuration: Clock input to clock output
• Input:Output ratio: 2:1
• Circuit count: 1
• Divider capability: Yes

The DS1087LU-40K+ is identified as a direct substitute based on identical electrical specifications and package dimensions. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The DS1087LU-40K+ is the direct functional equivalent of the DS1087LU-40K. Both devices share identical electrical specifications and package dimensions, ensuring pin-for-pin compatibility and functional interchangeability in circuit applications.

The DS1087LU-40K+ is recommended for new designs and production applications due to its active product status. The DS1087LU-40K is obsolete and should be replaced with the DS1087LU-40K+ where possible.

The DS1087LU-40K+ carries ROHS3 compliance certification, whereas the DS1087LU-40K is RoHS non-compliant. This distinction is significant for applications subject to environmental and regulatory requirements.
