Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1086Z is determined by strict equivalence across the following critical parameters:

• Frequency specification: Maximum operating frequency of 133MHz
• Package compatibility: 8-SOIC (0.154", 3.90mm Width) surface mount package
• Supply voltage range: 4.75V ~ 5.25V
• Functional architecture: Single-circuit spread spectrum clock generator with 1:1 input-to-output ratio
• Input/Output signal type: Clock input and clock output
• Operating temperature range: 0°C ~ 70°C
• Mounting technology: Surface mount

The DS1086Z+ qualifies as a direct substitute based on identical electrical specifications, package configuration, and functional characteristics. The primary distinction between these parts is product status and compliance certification.

Engineering Selection Recommendations

The DS1086Z+ is the direct functional equivalent of the DS1086Z across all electrical and mechanical parameters. Selection between these parts should be based on the following criteria:

DS1086Z: Use only when legacy component specifications explicitly require the obsolete part number or when existing inventory must be consumed. This part is RoHS non-compliant and carries obsolete product status.

DS1086Z+: Recommended for all new designs and ongoing production. This part maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance. The DS1086Z+ is supplied in tube packaging, which is standard for production environments.

For applications subject to RoHS or environmental compliance requirements, the DS1086Z+ is the appropriate selection. Both parts share identical supply voltage ranges, operating temperature specifications, frequency capabilities, and package footprints, ensuring direct substitution at the circuit board level.

Frequently Asked Questions (FAQ)

Q: Can DS1086Z+ be used as a direct replacement for DS1086Z in existing designs?

A: Yes. The DS1086Z+ is electrically and mechanically identical to the DS1086Z. Both parts operate at 133MHz maximum frequency, require 4.75V to 5.25V supply voltage, use the same 8-SOIC package, and provide identical clock generation functionality. No circuit modifications are required.

Q: What is the difference between DS1086Z and DS1086Z+?

A: The primary differences are product status and compliance certification. The DS1086Z is obsolete and RoHS non-compliant, while the DS1086Z+ is active and ROHS3 compliant. Electrical specifications, package configuration, and functional performance are identical.

Q: Are there any package differences between these parts?

A: Both parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package. The DS1086Z+ is supplied in tube packaging, which is standard for production quantities. This does not affect electrical compatibility or circuit board integration.

Q: What supply voltage range do these clock generators require?

A: Both the DS1086Z and DS1086Z+ require a supply voltage range of 4.75V to 5.25V. This specification must be maintained for proper operation.

Q: What is the maximum operating frequency for these parts?

A: Both parts operate at a maximum frequency of 133MHz. The input-to-output ratio is 1:1, and the parts include a divider function but no multiplier capability.

Q: Are these parts suitable for applications requiring RoHS compliance?

A: The DS1086Z is RoHS non-compliant. The DS1086Z+ is ROHS3 compliant and should be selected for applications subject to RoHS or environmental compliance requirements.

Q: What is the operating temperature range?

A: Both parts operate across a temperature range of 0°C to 70°C. This specification defines the valid operating environment for these clock generators.
