Key Parameters

Substitute Part Grouping Explanation

Substitution for the DS1806-010+ is determined by strict equivalence across the following critical parameters:

• Resistance value: 10kΩ
• Number of circuits: 6
• Number of taps: 64
• Interface type: Serial
• Taper characteristic: Linear
• Package type: 20-DIP
• Voltage supply range: 2.7V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C
• Memory type: Volatile
• Mounting type: Through Hole

Only components matching all these specifications qualify as direct substitutes. The DS1806-010+ serves as both the primary reference and the identified equivalent part.

Parameter Comparison

Engineering Selection Recommendations

The DS1806-010+ is ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements. With MSL rating of 1 (Unlimited), the component has no moisture sensitivity constraints for standard storage and handling. The Last Time Buy status indicates this part is being phased out; however, current inventory of 840 pieces is available as new original stock.

Selection of equivalent parts must maintain full parameter parity across all electrical and mechanical specifications listed in the Key Parameters section. The 20-DIP through-hole package is a critical constraint for PCB compatibility and cannot be substituted with alternative package types.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the DS1806-010+?

A: A valid substitute must match all critical parameters: 10kΩ resistance, 6 circuits, 64 taps, serial interface, linear taper, 20-DIP package, 2.7V–5.5V supply range, and –40°C to 85°C operating temperature. Any deviation in these specifications disqualifies the part as a direct substitute.

Q: Can I use a different package type as a substitute?

A: No. The 20-DIP (0.300", 7.62mm) through-hole package is a mechanical requirement for PCB compatibility. Alternative packages such as surface-mount variants are not compatible with designs specified for this component.

Q: What is the significance of the Last Time Buy status?

A: Last Time Buy indicates the manufacturer is discontinuing this part. Existing inventory should be evaluated for long-term production needs. Alternative sourcing strategies should be developed for future designs.

Q: Are there any compliance considerations for substitution?

A: Yes. Any substitute must maintain ROHS3 compliance and REACH unaffected status. MSL rating of 1 (Unlimited) indicates no special moisture handling requirements during storage or assembly.

Q: What role does the cascade pin feature play in substitution?

A: The cascade pin feature enables daisy-chaining of multiple DS1806-010+ devices for expanded control. Any substitute must include this feature to maintain system functionality in cascade configurations.
