Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS1682S/T&R is determined by strict equivalence across the following critical parameters:

• Base product number (DS1682 series)
• Functional type (Elapsed Time Counter)
• Memory capacity (10B)
• Serial interface protocol (I2C, 2-Wire)
• Physical package (8-SOIC with 0.154" / 3.90mm width)
• Supply voltage range (2.5V ~ 5.5V)
• Operating temperature range (-40°C ~ 85°C)
• Feature set (Alarm, EEPROM)

The substitute part DS1682S+T&R maintains identical electrical and mechanical specifications while differing in product status and packaging format. Both parts share the same base product number and functional characteristics, confirming direct substitutability at the component level.

Parameter Comparison

Engineering Selection Recommendations

The DS1682S+T&R is the direct functional equivalent of the obsolete DS1682S/T&R. Selection of the substitute part is supported by:

• Identical electrical specifications across all operating parameters
• Identical physical package dimensions and mounting requirements
• Active product status ensuring continued availability and supply chain support
• ROHS3 compliance, meeting current environmental and regulatory standards
• Verified DiGi-Electronics programmability status

The substitute part accommodates both Cut Tape and Digi-Reel® packaging formats, providing flexibility for different procurement and assembly workflows.

Frequently Asked Questions (FAQ)

Q: Can DS1682S+T&R directly replace DS1682S/T&R in existing designs?

A: Yes. Both parts share identical electrical and mechanical specifications, including supply voltage, operating temperature range, I2C interface protocol, memory capacity, and 8-SOIC package dimensions. No design modifications are required.

Q: What is the difference between the two part numbers?

A: The primary differences are product status and packaging format. DS1682S/T&R is obsolete and supplied in Tape & Reel format. DS1682S+T&R is active and available in both Cut Tape and Digi-Reel® formats. Electrical and functional performance are identical.

Q: Does the RoHS compliance difference affect compatibility?

A: No. ROHS3 compliance of the substitute part represents an improvement in environmental standards. The part remains electrically and mechanically compatible with designs originally specified for the non-compliant version.

Q: Are there any package or pinout differences?

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

Q: What supply voltage range should be used with either part?

A: Both parts operate across 2.5V to 5.5V supply voltage. Timekeeping current consumption is 4µA to 15µA at 3V to 5.5V.

Q: Can these parts be used interchangeably in procurement?

A: Yes. DS1682S+T&R is recommended for new procurement due to active product status and improved compliance certifications. Existing inventory of DS1682S/T&R remains functionally equivalent for current applications.
