Substitute Part Grouping Explanation

The DS1267BS-010+ qualifies as a direct substitute for the DS1267S-010 based on the following matching parameters:

• Resistance value: 10kΩ
• Number of circuits: 2
• Number of taps: 256
• Interface: Serial
• Taper: Linear
• Supply voltage: 5V
• Mounting type: Surface Mount
• Package type: 16-SOIC (0.295", 7.50mm Width)
• Operating temperature range: -40°C to 85°C
• Memory type: Volatile
• Tolerance: ±20%
• Temperature coefficient: 750ppm/°C
• Features: Cascade Pin

The substitution is valid across all critical electrical and mechanical parameters. Differences in wiper resistance (400Ω vs. 900Ω typical) and packaging format (tube vs. unspecified) do not affect functional compatibility in standard applications.

Engineering Selection Recommendations

The DS1267BS-010+ is the appropriate selection for new designs and production continuity. The original DS1267S-010 is obsolete and presents supply chain risk. The substitute part maintains complete electrical and mechanical compatibility while offering active product status and ROHS3 compliance. Both parts share identical functional specifications across resistance, circuit count, tap resolution, interface protocol, and operating parameters. The DS1267BS-010+ is available in tube packaging with confirmed inventory stock, supporting both prototype and production requirements.

Frequently Asked Questions (FAQ)

Q: Are the DS1267S-010 and DS1267BS-010+ pin-compatible? A: Yes. Both parts use the 16-SOIC package with identical pinout and electrical interface specifications.

Q: What is the difference in wiper resistance between these parts? A: The DS1267S-010 has a typical wiper resistance of 400Ω, while the DS1267BS-010+ has 900Ω typical. This parameter does not affect substitution eligibility for standard potentiometer applications.

Q: Can I use DS1267BS-010+ in place of DS1267S-010 in existing designs? A: Yes. The substitute maintains all critical electrical and mechanical parameters required for functional equivalence.

Q: What is the significance of the RoHS compliance difference? A: The DS1267BS-010+ is ROHS3 compliant, meeting current environmental and regulatory requirements. The obsolete DS1267S-010 is non-compliant. For new production, the compliant part is required.

Q: Are there packaging considerations when switching to the substitute? A: The DS1267BS-010+ is supplied in tube packaging. Both parts are surface mount components in the same 16-SOIC package format, requiring no PCB layout modifications.

Q: Is the serial interface protocol identical between these parts? A: Yes. Both parts implement serial interface control with identical protocol specifications and cascade pin functionality.
