Substitute Part Grouping Explanation

Substitution eligibility for the DS1267E-10 is determined by strict equivalence across the following critical parameters:

  • Resistance value: 10kΩ
  • Circuit configuration: 2 circuits
  • Tap resolution: 256 taps
  • Serial interface protocol
  • 5V supply voltage operation
  • Linear taper characteristic
  • 20-TSSOP package footprint and pinout compatibility
  • Volatile memory type
  • Operating temperature range: -40°C to 85°C

The DS1267BE-010+ meets all these criteria and is classified as a direct substitute. Differences in product status, RoHS compliance, and wiper resistance do not affect functional substitutability within the specified electrical and mechanical parameters.

Engineering Selection Recommendations

The DS1267BE-010+ is the direct substitute for the DS1267E-10. Both parts share identical electrical specifications, package geometry, and functional characteristics across all critical parameters. The primary distinction is product lifecycle status: the DS1267E-10 is obsolete, while the DS1267BE-010+ is active and available.

The DS1267BE-010+ offers additional compliance advantages. It meets ROHS3 requirements, whereas the DS1267E-10 is non-compliant. For new designs or systems requiring regulatory compliance, the DS1267BE-010+ is the appropriate selection. Both parts maintain REACH Unaffected status and EAR99 export classification.

The wiper resistance difference (400Ω typical for DS1267E-10 versus 900Ω typical for DS1267BE-010+) reflects manufacturing variation within the specified tolerance and does not constitute a functional incompatibility for standard potentiometer applications.

Frequently Asked Questions (FAQ)

Q: Can the DS1267BE-010+ directly replace the DS1267E-10 in existing designs?

A: Yes. The DS1267BE-010+ is electrically and mechanically equivalent. Pin configuration, package footprint, and all functional parameters are identical. No circuit modifications are required.

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

A: Wiper resistance (400Ω vs. 900Ω) represents typical on-resistance of the internal switching network. Both values fall within acceptable operating ranges for serial-controlled potentiometer applications and do not affect substitutability.

Q: Why is the DS1267E-10 listed as obsolete?

A: Obsolescence indicates the part is no longer manufactured or supported by Analog Devices Inc./Maxim Integrated. The DS1267BE-010+ is the active production equivalent.

Q: Are there compliance differences between these parts?

A: Yes. The DS1267BE-010+ is ROHS3 compliant, while the DS1267E-10 is non-compliant. For applications subject to RoHS regulations, the DS1267BE-010+ is required.

Q: Is the 20-TSSOP package identical between both parts?

A: Yes. Both parts use the 20-TSSOP package with 0.173" width and 4.40mm dimensions. PCB footprints and assembly processes are identical.

Q: What packaging options are available for the substitute part?

A: The DS1267BE-010+ is supplied in tube packaging. The DS1267E-10 packaging specification was not provided in the available data.
