Substitute Part Grouping Explanation

Substitution for the DS1023S-50/T&R is determined by strict equivalence across the following critical parameters:

• Functional Specification: 1-Shot, Programmable delay line with 256 taps
• Delay Characteristics: Delay to 1st tap of 16.5ns, tap increment of 500 ps, total available delay of 127.5ns
• Independent Delay Channels: 1 independent delay
• Electrical Specifications: Supply voltage range 4.75V ~ 5.25V
• Operating Temperature Range: 0°C ~ 70°C
• Package Compatibility: 16-SOIC (0.295", 7.50mm Width) surface mount
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected

The DS1023S-50+T meets all these criteria and serves as a direct functional equivalent. The primary distinction between the main part and its substitute is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The DS1023S-50+T is a direct substitute for the DS1023S-50/T&R. Both components are manufactured by Analog Devices Inc./Maxim Integrated and share identical electrical, functional, and mechanical specifications. The substitute part is currently in Active product status, ensuring long-term availability and supply chain continuity compared to the Obsolete main part.

Both parts maintain ROHS3 compliance and REACH Unaffected status, satisfying regulatory requirements for industrial and commercial applications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints during storage and handling.

For applications currently using the DS1023S-50/T&R, the DS1023S-50+T provides equivalent performance without design modifications or PCB layout changes, as the 16-SOIC package dimensions and pinout remain unchanged.

Frequently Asked Questions (FAQ)

Q: Can the DS1023S-50+T be used as a direct replacement for the DS1023S-50/T&R?

A: Yes. Both parts are electrically and mechanically identical. The DS1023S-50+T is the active equivalent with identical delay line specifications, tap configuration, supply voltage range, and operating temperature range.

Q: What is the difference between DS1023S-50/T&R and DS1023S-50+T?

A: The primary difference is product status and packaging format. The DS1023S-50/T&R is Obsolete, while the DS1023S-50+T is Active. Both use the same 16-SOIC package and have identical electrical specifications.
