DS1312S/T&R Equivalent & Substitute Parts

Part Overview

The DS1312S/T&R is a nonvolatile RAM controller manufactured by Analog Devices Inc./Maxim Integrated, designed for memory control applications requiring battery backup and reset functionality. This component is classified as obsolete, which necessitates identification of equivalent substitute parts for ongoing production and maintenance requirements. The part is housed in a 16-SOIC surface mount package and operates within a 4.75V to 5.5V supply voltage range across an industrial temperature spectrum of -40°C to 85°C.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1312S/T&R is determined by strict alignment across the following critical parameters:

• Base Product Number: DS1312 (same functional device)
• Controller Type: Nonvolatile RAM (identical functional classification)
• Voltage - Supply: 4.75V ~ 5.5V (identical operating range)
• Operating Temperature: -40°C ~ 85°C (identical temperature range)
• Mounting Type: Surface Mount (identical assembly method)
• Package / Case: 16-SOIC (0.295", 7.50mm Width) (identical physical footprint)
• RoHS Status: ROHS3 Compliant (identical environmental compliance)
• Moisture Sensitivity Level: 1 (Unlimited) (identical handling requirements)

The primary distinction between the main part and its substitute lies in packaging configuration and product status. The DS1312S+T&R represents an active production variant with tape and reel packaging, whereas the DS1312S/T&R is an obsolete variant with standard packaging.

Parameter Comparison

Engineering Selection Recommendations

The DS1312S+T&R is the direct substitute for the obsolete DS1312S/T&R. Both parts share identical electrical specifications, thermal operating ranges, and physical package dimensions. The substitute maintains full ROHS3 compliance and REACH unaffected status, ensuring regulatory alignment with current environmental standards.

The primary advantage of the DS1312S+T&R is its active product status and availability in tape and reel packaging, which facilitates automated assembly processes and ensures continued supply chain access. The tape and reel configuration is standard for high-volume surface mount production environments.

Frequently Asked Questions (FAQ)

Q: Can the DS1312S+T&R be used as a direct replacement for the DS1312S/T&R?

A: Yes. Both parts are identical in electrical performance, thermal characteristics, and physical package dimensions. The DS1312S+T&R is the active production equivalent.

Q: What is the difference between standard packaging and tape & reel packaging?

A: Tape and reel (TR) packaging is configured for automated pick-and-place assembly equipment, while standard packaging is typically used for manual or lower-volume assembly. The components themselves are electrically and mechanically identical.

Q: Are there any compliance differences between these parts?

A: No. Both parts maintain ROHS3 compliance, REACH unaffected status, and identical moisture sensitivity levels. Regulatory and environmental certifications are equivalent.

Q: Why is the DS1312S/T&R listed as obsolete?

A: Obsolete status indicates the part is no longer in active production. The DS1312S+T&R represents the current active production variant and is the recommended source for new procurement.

Q: Will the DS1312S+T&R fit the same PCB footprint as the DS1312S/T&R?

A: Yes. Both parts use the identical 16-SOIC package with 0.295" width and 7.50mm dimensions, ensuring direct PCB compatibility.
