Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1100Z-75 is determined by strict equivalence across the following critical parameters:

• Number of taps: 5 taps (fixed requirement)
• Delay topology: Nonprogrammable function
• Delay to first tap: 15ns
• Tap increment: 15ns
• Total available delay: 75ns
• Number of independent delays: 1
• Supply voltage range: 4.75V ~ 5.25V
• Operating temperature range: -40°C ~ 85°C
• Package type: 8-SOIC (0.154", 3.90mm Width)
• Mounting type: Surface Mount

The DS1100Z-75+ meets all electrical and mechanical substitution criteria, maintaining identical delay characteristics, pin configuration, and functional behavior while offering active product status and improved compliance posture.

Parameter Comparison

Engineering Selection Recommendations

The DS1100Z-75+ is the direct functional equivalent for applications currently using the DS1100Z-75. Selection of the substitute part is supported by:

• Identical electrical specifications across all delay parameters
• Matching package and pin configuration enabling direct PCB compatibility
• Active product status ensuring long-term availability and supply chain continuity
• ROHS3 compliance of the substitute part, addressing regulatory requirements not met by the obsolete variant
• Equivalent moisture sensitivity classification and REACH status

For new designs or system refreshes, the DS1100Z-75+ is the appropriate selection. For legacy system maintenance, the DS1100Z-75+ provides functional continuity with improved compliance characteristics.

Frequently Asked Questions (FAQ)

Q: Can DS1100Z-75+ be used as a direct replacement for DS1100Z-75?

A: Yes. The DS1100Z-75+ is electrically and mechanically equivalent. All delay parameters, supply voltage, operating temperature range, and 8-SOIC package dimensions are identical, enabling direct substitution without circuit modification.

Q: What is the difference between DS1100Z-75 and DS1100Z-75+?

A: The primary differences are product status and compliance. The DS1100Z-75 is obsolete and RoHS non-compliant, while the DS1100Z-75+ is active and ROHS3 compliant. Electrical and functional specifications are identical.

Q: Are there any packaging differences between these parts?

A: Both parts use the 8-SOIC (0.154", 3.90mm Width) surface mount package. The DS1100Z-75+ is supplied in tube packaging, while the original part number does not specify packaging format. Pin configuration and PCB footprint are identical.

Q: What supply voltage range is required for operation?

A: Both the DS1100Z-75 and DS1100Z-75+ operate within a 4.75V to 5.25V supply voltage range. This specification applies to both parts without variation.

Q: Is the DS1100Z-75+ suitable for the full operating temperature range of the original part?

A: Yes. The DS1100Z-75+ maintains the -40°C to 85°C operating temperature range specified for the DS1100Z-75, ensuring compatibility across all environmental conditions.
