Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS1004Z-3 is determined by the following critical parameters:

• Package Compatibility: Both parts must use 8-SOIC (0.154", 3.90mm Width) surface mount packaging to ensure PCB layout compatibility
• Functional Classification: Both parts must be nonprogrammable delay line ICs with 5 taps
• Supply Voltage Range: Both parts must operate within 4.75V to 5.25V
• Number of Independent Delays: Both parts must have 1 independent delay channel
• Delay Characteristics: Total delay and tap increment values determine application suitability

The DS1100Z-20+ qualifies as a direct substitute based on matching package type, functional classification, tap count, supply voltage range, and independent delay configuration. Differences in delay timing parameters and operating temperature range reflect design variations within the same product family.

Parameter Comparison

Engineering Selection Recommendations

The DS1100Z-20+ is an active product with ROHS3 compliance, providing a path forward from the obsolete DS1004Z-3. The substitute maintains identical package geometry and supply voltage specifications, ensuring mechanical and electrical compatibility at the board level.

The DS1100Z-20+ offers an extended operating temperature range (-40°C to 85°C) compared to the DS1004Z-3 (0°C to 70°C), providing greater thermal margin for applications requiring wider environmental performance. The increased total delay specification (20ns versus 17ns) and modified tap increment (4ns versus 3ns) reflect design differences that must be evaluated against specific application timing requirements.

Selection of the DS1100Z-20+ is appropriate for new designs and legacy system support where RoHS3 compliance is required or preferred. Applications with strict timing constraints tied to the original 17ns delay specification require detailed timing analysis to confirm compatibility with the 20ns delay characteristic.

Frequently Asked Questions (FAQ)

Q: Can the DS1100Z-20+ be used as a direct replacement for the DS1004Z-3 in existing designs?

A: The DS1100Z-20+ shares the same 8-SOIC package footprint and supply voltage range, enabling physical and electrical board-level compatibility. However, the increased total delay (20ns versus 17ns) and different tap increment (4ns versus 3ns) require verification that application timing specifications accommodate these parameter differences.

Q: What is the significance of the operating temperature range difference?

A: The DS1004Z-3 operates from 0°C to 70°C, while the DS1100Z-20+ operates from -40°C to 85°C. The extended range of the substitute provides greater thermal margin and suitability for applications requiring wider environmental performance. Applications operating within the original 0°C to 70°C window are compatible with both parts.

Q: Why is the DS1004Z-3 listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured or supported by Analog Devices Inc./Maxim Integrated. The DS1100Z-20+ represents the active alternative within the same product family, ensuring continued availability and support for delay line applications.

Q: Are there packaging or mounting differences between these parts?

A: Both parts use identical 8-SOIC (0.154", 3.90mm Width) surface mount packaging. No PCB layout modifications are required for physical substitution.

Q: What does RoHS3 compliance mean for the DS1100Z-20+?

A: ROHS3 compliance indicates the DS1100Z-20+ meets Restriction of Hazardous Substances Directive requirements, restricting the use of specified hazardous materials. The DS1004Z-3 is RoHS non-compliant. Selection of the compliant substitute is necessary for applications subject to RoHS regulatory requirements.
