Key Parameters

Substitute Part Grouping Explanation

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

• Resistance value: 10kΩ
• Circuit count: 6 circuits
• Tap count: 64 taps
• Interface protocol: Serial
• Taper characteristic: Linear
• Supply voltage range: 2.7V ~ 5.5V
• Operating temperature range: -40°C ~ 85°C
• Package form factor: 20-DIP (0.300", 7.62mm)
• Mounting technology: Through Hole

The DS1806-010+ qualifies as a direct substitute based on complete parameter alignment across all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

The DS1806-010+ provides functional equivalence to the DS1806-010 across all electrical and mechanical parameters. The primary distinction lies in product lifecycle status and regulatory compliance. The DS1806-010 is obsolete, whereas the DS1806-010+ carries Last Time Buy status, indicating extended but finite availability. The DS1806-010+ achieves ROHS3 compliance, whereas the original DS1806-010 is non-compliant. For new designs or system refreshes, the DS1806-010+ is the appropriate selection. For legacy system maintenance requiring exact historical equivalence, the DS1806-010+ maintains full functional compatibility.

Frequently Asked Questions (FAQ)

Q: Can the DS1806-010+ directly replace the DS1806-010 in existing circuits?

A: Yes. The DS1806-010+ is electrically and mechanically equivalent. All pin configurations, signal protocols, voltage ranges, and operating conditions are identical. Through-hole mounting and 20-DIP package dimensions are unchanged.

Q: What is the significance of the RoHS compliance difference?

A: The DS1806-010+ meets ROHS3 standards, restricting hazardous substances in manufacturing. The DS1806-010 does not meet this standard. For applications subject to RoHS regulations or environmental compliance requirements, the DS1806-010+ is mandatory.

Q: Why is the DS1806-010 marked as obsolete?

A: Obsolescence indicates the manufacturer has discontinued production. The DS1806-010+ carries Last Time Buy status, meaning limited stock remains available before complete discontinuation. Procurement planning should prioritize the DS1806-010+ for future applications.

Q: Are there any performance differences between these parts?

A: No. Both parts share identical electrical specifications: 10kΩ resistance, 64 taps, 6 circuits, serial interface, linear taper, 2.7V–5.5V supply range, and -40°C to 85°C operating temperature. Temperature coefficient, wiper resistance, and tolerance are equivalent.

Q: What inventory considerations apply?

A: The DS1806-010 has 2100 units in stock (new original). The DS1806-010+ has 840 units available. Given Last Time Buy status on the DS1806-010+, procurement should account for finite availability and plan accordingly for long-term system support.
