DS1110S-250 Equivalent & Substitute Parts

Part Overview

The DS1110S-250 is a nonprogrammable delay line IC manufactured by Analog Devices Inc./Maxim Integrated, designed for clock and timing applications. This 10-tap delay line device provides a fixed 250ns total delay with 25ns tap increments in a 16-SOIC surface mount package. The main part number DS1110S-250 is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1110S-250 is determined by strict equivalence across the following critical parameters:

• Number of Taps/Steps: 10
• Function: Nonprogrammable
• Delay to 1st Tap: 25ns
• Tap Increment: 25ns
• Available Total Delays: 250ns
• Number of Independent Delays: 1
• Voltage - Supply: 4.75V ~ 5.25V
• Operating Temperature: -40°C ~ 85°C
• Package / Case: 16-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount

The DS1110S-250+ qualifies as a direct substitute based on identical electrical specifications and package configuration. The primary distinction between these parts is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The DS1110S-250+ is the direct functional equivalent to the DS1110S-250. Both parts share identical electrical and mechanical specifications, ensuring pin-for-pin and functional compatibility in circuit applications.

The DS1110S-250+ offers two significant advantages over the obsolete DS1110S-250:

• Active product status ensures continued availability and manufacturer support
• ROHS3 compliance meets current environmental and regulatory requirements, whereas the DS1110S-250 is RoHS non-compliant

For new designs and ongoing system support, the DS1110S-250+ is the appropriate selection. For legacy systems currently using the DS1110S-250, direct substitution with the DS1110S-250+ is electrically and mechanically valid without circuit modification.

Frequently Asked Questions (FAQ)

Q: Are DS1110S-250 and DS1110S-250+ pin-for-pin compatible?

A: Yes. Both parts use the 16-SOIC package with identical pinout and electrical characteristics. Direct substitution on the PCB is possible without layout changes.

Q: What is the functional difference between these parts?

A: There is no functional difference. Both are nonprogrammable 10-tap delay line ICs with 250ns total delay and 25ns tap increments. Electrical performance is identical.

Q: Why is the DS1110S-250 listed as obsolete?

A: The DS1110S-250 has been discontinued by the manufacturer. The DS1110S-250+ is the active replacement part.

Q: Does RoHS compliance affect circuit performance?

A: No. RoHS compliance relates to material composition and environmental standards, not electrical or timing performance. Both parts operate identically in circuit.

Q: Can I use DS1110S-250+ in a design originally specified for DS1110S-250?

A: Yes. The DS1110S-250+ is a direct substitute with identical electrical specifications, package, and pinout. No design changes are required.

Q: What packaging is available for the DS1110S-250+?

A: The DS1110S-250+ is supplied in tube packaging. The original DS1110S-250 packaging specification was not provided.
