Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1314S/T&R is determined by strict equivalence across the following critical parameters:

• Controller Type: Nonvolatile RAM functionality
• Voltage Supply Range: 3V ~ 3.6V operation
• Operating Temperature Range: -40°C ~ 85°C
• Package / Case: 16-SOIC (0.295", 7.50mm Width)
• Mounting Type: Surface Mount
• RoHS Compliance: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

The DS1314S+T&R meets all substitution criteria as an active equivalent part manufactured by the same supplier with identical electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The DS1314S+T&R is a direct functional equivalent to the DS1314S/T&R. Both parts share identical electrical specifications, thermal operating range, and mechanical packaging. The primary distinction is product status: the DS1314S+T&R is actively manufactured and maintained, while the DS1314S/T&R is obsolete.

For new designs and production continuity, the DS1314S+T&R is the appropriate selection. Both parts maintain ROHS3 compliance and identical moisture sensitivity ratings, ensuring regulatory and environmental consistency. The higher inventory availability of the DS1314S+T&R (3377 units versus 977 units) supports supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the DS1314S+T&R be used as a direct replacement for the DS1314S/T&R?

A: Yes. The DS1314S+T&R is electrically and mechanically identical to the DS1314S/T&R across all specified parameters, including voltage supply range, operating temperature, package format, and functional classification as a nonvolatile RAM controller.

Q: What is the difference between DS1314S/T&R and DS1314S+T&R?

A: The parts are functionally equivalent. The difference in part number designation reflects packaging or tape/reel configuration variations. Both maintain identical electrical and thermal specifications.

Q: Are there any compliance or regulatory differences between these parts?

A: No. Both parts are ROHS3 compliant, REACH unaffected, and carry identical moisture sensitivity ratings (MSL 1 - Unlimited). They meet the same regulatory and environmental standards.

Q: What is the 16-SOIC package specification?

A: The 16-SOIC (Small Outline Integrated Circuit) package measures 0.295 inches in width with a body length of 7.50mm. This is a surface mount package format suitable for automated assembly processes.

Q: Why is the DS1314S/T&R marked as obsolete?

A: Obsolescence indicates the part is no longer in active production. The DS1314S+T&R serves as the active production equivalent and should be specified for new designs and ongoing procurement.
