Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS1004Z-4 is determined by the following critical parameters that must remain compatible:

• Package Type: Both parts must use 8-SOIC (0.154", 3.90mm Width) surface mount packaging to ensure PCB layout compatibility
• Number of Taps: Both parts must feature 5 taps to maintain functional equivalence
• Function Type: Both parts must be nonprogrammable delay line ICs
• Tap Increment: Both parts must maintain 4ns tap increment spacing
• Supply Voltage Range: Both parts must operate within 4.75V ~ 5.25V
• Total Delay Range: Substitute parts must provide delay values within acceptable operational margins (20ns to 21ns range)
• Manufacturer: Parts must originate from Analog Devices Inc./Maxim Integrated product line

The DS1100Z-20+ meets all substitution criteria as an active product with compatible electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The DS1100Z-20+ is the qualified substitute for the obsolete DS1004Z-4 based on the following engineering criteria:

Product Status: The DS1100Z-20+ is an active product with current manufacturing support, whereas the DS1004Z-4 is obsolete. This transition ensures continued component availability and supply chain reliability.

Regulatory Compliance: The DS1100Z-20+ achieves ROHS3 compliance, meeting current environmental and regulatory requirements. The DS1004Z-4 is RoHS non-compliant, which may present procurement and regulatory challenges in modern manufacturing environments.

Electrical Compatibility: Both parts operate within identical supply voltage ranges (4.75V ~ 5.25V) and maintain the same tap increment (4ns). The DS1100Z-20+ provides an extended operating temperature range (-40°C ~ 85°C) compared to the DS1004Z-4 (0°C ~ 70°C), offering improved performance margin in temperature-sensitive applications.

Mechanical Compatibility: Both parts use identical 8-SOIC (0.154", 3.90mm Width) surface mount packaging, ensuring direct PCB layout compatibility without redesign.

Delay Specification Variation: The DS1100Z-20+ provides 20ns total delay versus 21ns for the DS1004Z-4. This 1ns difference represents a 4.8% variation and must be evaluated against specific circuit timing requirements. Both parts maintain the same 4ns tap increment structure.

Frequently Asked Questions (FAQ)

Q: Can the DS1100Z-20+ be used as a direct replacement for the DS1004Z-4 without PCB modifications?

A: Yes. Both parts use identical 8-SOIC (0.154", 3.90mm Width) surface mount packaging with the same pin configuration. No PCB layout changes are required for mechanical and electrical connectivity.

Q: What is the significance of the 1ns delay difference between the two parts?

A: The DS1004Z-4 provides 21ns total delay while the DS1100Z-20+ provides 20ns. This 1ns difference must be evaluated within the context of your specific timing requirements. Both parts maintain identical 4ns tap increment spacing, allowing selection of intermediate delay values through tap selection.

Q: Does the DS1100Z-20+ operate at the same supply voltage as the DS1004Z-4?

A: Yes. Both parts operate within the identical supply voltage range of 4.75V ~ 5.25V. No power supply modifications are necessary.

Q: What is the advantage of the extended operating temperature range in the DS1100Z-20+?

A: The DS1100Z-20+ operates from -40°C to 85°C, compared to the DS1004Z-4 range of 0°C to 70°C. This extended range provides improved performance margin in temperature-sensitive applications and meets requirements for industrial and automotive environments.

Q: Is the DS1100Z-20+ RoHS compliant?

A: Yes. The DS1100Z-20+ is ROHS3 compliant. The DS1004Z-4 is RoHS non-compliant. This compliance improvement may be required for new production designs and procurement in regulated markets.

Q: Are both parts classified as nonprogrammable delay line ICs?

A: Yes. Both the DS1004Z-4 and DS1100Z-20+ are nonprogrammable 5-tap delay line ICs with fixed delay characteristics. No programming or configuration is required.

Q: What is the moisture sensitivity level for both parts?

A: Both parts have a Moisture Sensitivity Level (MSL) of 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling.
