Key Parameters

Substitute Part Grouping Explanation

Substitution for the DS1672U-2+ is determined by strict equivalence across the following critical parameters:

• Interface Protocol: I2C, 2-Wire Serial communication
• Time & Date Format: Binary representation
• Package Specification: 8-TSSOP, 8-MSOP (0.118", 3.00mm Width)
• Voltage Supply Range: 1.8V ~ 2.2V (primary), 1.3V ~ 3.63V (battery backup)
• Operating Temperature Range: -40°C ~ 85°C
• Mounting Type: Surface Mount
• Functional Features: Trickle-Charger capability
• Compliance: ROHS3 Compliant

Only components meeting all these parameters qualify as direct substitutes. The DS1672U-2+ represents the complete functional specification for this product line.

Parameter Comparison

Engineering Selection Recommendations

The DS1672U-2+ is classified as Obsolete. For applications requiring this RTC IC Binary Counter, the direct equivalent DS1672U-2+ remains the specified component when available from authorized inventory sources. Both the main part and its direct substitute maintain identical electrical specifications, package dimensions, and compliance certifications (ROHS3 Compliant, MSL Level 1).

Selection should prioritize components with verified ROHS3 compliance and confirmed Moisture Sensitivity Level 1 rating to ensure reliability in production environments. The 8-TSSOP, 8-MSOP package format is critical for PCB layout compatibility and must not be altered during component selection.

Frequently Asked Questions (FAQ)

Q: What makes DS1672U-2+ a direct substitute for itself? A: The DS1672U-2+ is the specified part number for this RTC IC Binary Counter. Direct substitution occurs when the manufacturer part number, electrical parameters, package specification, and compliance certifications are identical.

Q: Are there alternative package options for the DS1672U-2+? A: The DS1672U-2+ is specified exclusively in the 8-TSSOP, 8-MSOP (0.118", 3.00mm Width) Surface Mount package. Alternative packages would constitute a different part number and are not substitutes.

Q: What is the significance of the I2C 2-Wire Serial interface for substitution? A: The I2C 2-Wire Serial interface is a critical functional parameter. Any substitute must support identical I2C protocol and 2-Wire Serial communication to ensure firmware and hardware compatibility without redesign.

Q: Why is binary time and date format important for substitution? A: Binary format is a specific data representation method. Substitutes must use identical binary format to maintain compatibility with existing firmware, register mapping, and data interpretation routines.

Q: What does ROHS3 Compliant status mean for component selection? A: ROHS3 Compliant indicates the component meets Restriction of Hazardous Substances Directive requirements. This certification is mandatory for many industrial and commercial applications and must be maintained in substitute selection.

Q: Is the trickle-charger feature essential for substitution? A: Yes. The trickle-charger feature is a specified functional characteristic of the DS1672U-2+. Any substitute must include this capability to maintain system functionality during power loss conditions.

Q: What is Moisture Sensitivity Level 1 (MSL 1)? A: MSL 1 indicates unlimited shelf life without moisture exposure restrictions. This is the most favorable moisture sensitivity rating and ensures the component can be stored and handled without special desiccant packaging requirements.
