Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1267S-010+ is determined by strict equivalence across the following critical parameters:

• Resistance value: 10kΩ
• Circuit configuration: 2 circuits
• Tap count: 256 taps
• Interface protocol: Serial
• Taper characteristic: Linear
• Supply voltage: 5V
• Memory architecture: Volatile
• Package form factor: 16-SOIC
• Operating temperature range: -40°C ~ 85°C
• Tolerance specification: ±20%

The DS1267BS-010+ meets all substitution criteria. Differences in wiper resistance (400Ω vs. 900Ω) and product status do not affect functional substitutability for standard applications, as wiper resistance is a secondary characteristic that does not alter the primary potentiometer function or interface compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DS1267BS-010+ is the qualified substitute for the obsolete DS1267S-010+. Both parts are manufactured by the same supplier (Analog Devices Inc./Maxim Integrated) and share identical electrical and mechanical specifications across all primary functional parameters.

The DS1267BS-010+ offers the advantage of active product status, ensuring continued availability and manufacturing support. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for new designs and legacy system support.

The difference in wiper resistance (400Ω vs. 900Ω) represents a secondary characteristic that does not impact serial interface protocol, resistance value, tap resolution, or circuit configuration. This parameter variation is within normal manufacturing tolerances for digital potentiometer devices and does not affect compatibility in standard data acquisition applications.

Frequently Asked Questions (FAQ)

Q: Can DS1267BS-010+ directly replace DS1267S-010+ in existing designs?

A: Yes. The DS1267BS-010+ is a direct functional equivalent. Both parts share identical resistance value, circuit count, tap resolution, serial interface, supply voltage, operating temperature range, and 16-SOIC package form factor. No circuit modifications are required.

Q: What is the significance of the different wiper resistance values?

A: Wiper resistance (400Ω vs. 900Ω) is a secondary characteristic that affects only the impedance of the wiper contact point. This parameter does not alter the primary potentiometer function, serial communication protocol, or resistance range. Standard applications are unaffected by this variation.

Q: Why is the main part listed as obsolete?

A: The DS1267S-010+ has reached end-of-life status with the manufacturer. The DS1267BS-010+ remains in active production, providing a path for design continuity and supply chain stability.

Q: Are there any compliance or certification differences?

A: No. Both parts maintain identical RoHS3 compliance and REACH unaffected status. No additional qualification or testing is required for substitution.

Q: Is the packaging different between these parts?

A: Both parts use 16-SOIC surface mount packaging with identical dimensions (0.295", 7.50mm width). Packaging compatibility is complete. The DS1267BS-010+ is supplied in tube packaging, while the main part packaging is not specified.
