Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1312S-2 is determined by the following critical parameters:

• Controller Type: Must be Nonvolatile RAM
• Voltage Supply Range: Must be 4.75V ~ 5.5V
• Operating Temperature Range: Must be -40°C ~ 85°C
• Mounting Type: Must be Surface Mount
• Package / Case: Must be 8-SOIC (0.154", 3.90mm Width)
• Moisture Sensitivity Level: Must be 1 (Unlimited)

The DS1312S-2+ meets all these criteria and is therefore classified as a direct substitute. Both parts share identical electrical specifications and mechanical compatibility, differing only in product status and RoHS compliance classification.

Parameter Comparison

Engineering Selection Recommendations

The DS1312S-2+ is the direct substitute for the obsolete DS1312S-2. Both parts are manufactured by the same supplier and share identical electrical and mechanical specifications. The primary distinction is product status: the DS1312S-2+ is currently in active production, whereas the DS1312S-2 is obsolete.

The DS1312S-2+ offers improved compliance status, meeting ROHS3 requirements compared to the non-compliant status of the original part. This makes the DS1312S-2+ the preferred choice for new designs and applications requiring regulatory compliance.

Frequently Asked Questions (FAQ)

Q: Can the DS1312S-2+ be used as a direct replacement for the DS1312S-2?

A: Yes. The DS1312S-2+ is a direct substitute. Both parts have identical voltage supply ranges (4.75V ~ 5.5V), operating temperature ranges (-40°C ~ 85°C), package specifications (8-SOIC), and controller functionality (Nonvolatile RAM).

Q: What is the difference between DS1312S-2 and DS1312S-2+?

A: The primary differences are product status and RoHS compliance. The DS1312S-2 is obsolete and RoHS non-compliant, while the DS1312S-2+ is in active production and ROHS3 compliant. Electrical and mechanical specifications are identical.

Q: Are there any package or pinout differences?

A: No. Both parts use the 8-SOIC (0.154", 3.90mm Width) package with identical pin configurations and mechanical dimensions.

Q: Is the DS1312S-2+ suitable for applications requiring RoHS compliance?

A: Yes. The DS1312S-2+ meets ROHS3 compliance requirements, making it suitable for applications with regulatory compliance mandates.

Q: What is the moisture sensitivity level for these parts?

A: Both the DS1312S-2 and DS1312S-2+ have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.
