DS1100LU-30/T&R Equivalent & Substitute Parts

Part Overview

The DS1100LU-30/T&R is a nonprogrammable delay line IC manufactured by Analog Devices Inc./Maxim Integrated, featuring 5 taps with a total delay of 30ns. This component is classified as obsolete, which necessitates identification of functionally equivalent alternatives for ongoing design support and procurement. The part operates within the 3V to 3.6V supply range and is housed in an 8-TSSOP/8-MSOP surface mount package suitable for timing and signal delay applications.

Substitute Part Grouping Explanation

Substitution eligibility for the DS1100LU-30/T&R is determined by strict equivalence across the following critical parameters:

• Number of Taps/Steps: 5
• Function: Nonprogrammable
• Delay to 1st Tap: 6ns
• Tap Increment: 6ns
• Available Total Delays: 30ns
• Number of Independent Delays: 1
• Voltage - Supply: 3V ~ 3.6V
• Operating Temperature: -40°C ~ 85°C
• Package / Case: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width)
• Supplier Device Package: 8-uMAX/uSOP

The DS1100LU-30+T meets all electrical and mechanical substitution criteria. The primary distinction is packaging format: the substitute is supplied in Tape & Reel (TR) configuration versus the original part's packaging designation, and the substitute maintains active product status with ROHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The DS1100LU-30+T is the direct functional equivalent of the DS1100LU-30/T&R. Both parts are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical specifications and physical package dimensions. The substitute part offers the advantage of active product status, ensuring continued availability and manufacturing support. Additionally, the DS1100LU-30+T carries ROHS3 compliance, meeting current environmental and regulatory requirements, whereas the original part is RoHS non-compliant. The packaging format difference (Tape & Reel) does not affect electrical performance or board-level compatibility. Selection of the DS1100LU-30+T is appropriate for new designs and legacy system updates requiring this delay line function.

Frequently Asked Questions (FAQ)

Q: Are the DS1100LU-30/T&R and DS1100LU-30+T electrically identical?

A: Yes. Both parts feature identical delay characteristics (5 taps, 6ns first tap delay, 6ns tap increment, 30ns total delay), supply voltage range (3V to 3.6V), operating temperature range (-40°C to 85°C), and nonprogrammable function.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and compliance. The DS1100LU-30+T is an active product with ROHS3 compliance, while the DS1100LU-30/T&R is obsolete and RoHS non-compliant. The packaging format also differs: the substitute uses Tape & Reel (TR) configuration.

Q: Will the DS1100LU-30+T fit the same PCB footprint?

A: Yes. Both parts use the 8-TSSOP/8-MSOP package with 0.118" (3.00mm) width, ensuring identical board-level compatibility and pin configuration.

Q: Is the Tape & Reel packaging suitable for automated assembly?

A: Yes. Tape & Reel packaging is standard for automated pick-and-place assembly processes and is compatible with standard component feeders.

Q: Can the DS1100LU-30+T be used as a direct replacement in existing designs?

A: Yes. The DS1100LU-30+T is a direct substitute with no design modifications required. It maintains full functional and mechanical compatibility with the original part.
