Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1801E-014 is determined by strict equivalence across the following critical parameters:

• Resistance value: 45kΩ (exact match required)
• Circuit configuration: 2 circuits (exact match required)
• Tap count: 65 taps (exact match required)
• Interface protocol: Serial (exact match required)
• Taper characteristic: Logarithmic (exact match required)
• Supply voltage range: 2.7V ~ 5.5V (exact match required)
• Operating temperature range: -40°C ~ 85°C (exact match required)
• Package designation: 14-TSSOP (exact match required)

The DS1801E-014+ qualifies as a direct substitute based on complete alignment with all electrical and mechanical parameters. The primary distinction between the main part and substitute is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The DS1801E-014+ is the direct equivalent substitute for the DS1801E-014. Selection of the DS1801E-014+ is supported by the following factors:

• Active product status ensures continued availability and manufacturer support
• ROHS3 compliance certification meets current environmental and regulatory requirements
• Identical electrical performance across all specified parameters
• Identical mechanical compatibility and pin configuration
• Same base product number (DS1801) confirms design lineage and functional equivalence

The transition from DS1801E-014 to DS1801E-014+ does not require circuit redesign or layout modification.

Frequently Asked Questions (FAQ)

Q: Can DS1801E-014+ be used as a direct replacement for DS1801E-014?

A: Yes. The DS1801E-014+ is electrically and mechanically identical to the DS1801E-014 across all specified parameters. No circuit modifications are required.

Q: What is the primary difference between DS1801E-014 and DS1801E-014+?

A: The DS1801E-014+ has active product status and ROHS3 compliance certification, whereas the DS1801E-014 is obsolete and RoHS non-compliant. Electrical and mechanical specifications are identical.

Q: Are there packaging differences between these parts?

A: Both parts use 14-TSSOP surface mount packaging with identical dimensions (0.173", 4.40mm width). The DS1801E-014+ is supplied in tube packaging, while the DS1801E-014 packaging type was not specified.

Q: What parameters must match exactly for substitution eligibility?

A: Resistance value (45kΩ), circuit count (2), tap count (65), interface type (serial), taper (logarithmic), supply voltage range (2.7V ~ 5.5V), operating temperature range (-40°C ~ 85°C), and package type (14-TSSOP) must all match exactly.

Q: Is the DS1801E-014+ suitable for new designs?

A: Yes. The active product status and ROHS3 compliance make the DS1801E-014+ appropriate for new design implementations.
