Parameter Comparison

Engineering Selection Recommendations

The DS1267BE-050+ is the direct active equivalent for the obsolete DS1267E-50+. Both parts maintain identical electrical specifications, package geometry, and compliance certifications (ROHS3 and REACH). The DS1267BE-050+ is currently in active production status with established supply availability, making it the appropriate selection for new designs and end-of-life replacement scenarios.

Frequently Asked Questions (FAQ)

Q: Can DS1267BE-050+ be used as a direct replacement for DS1267E-50+ in existing designs?

A: Yes. The DS1267BE-050+ is electrically and mechanically identical to the DS1267E-50+. Both parts share the same 20-TSSOP package footprint, pinout, and functional specifications. No design modifications are required.

Q: What is the difference between DS1267E-50+ and DS1267BE-050+?

A: The primary difference is product status. DS1267E-50+ is obsolete, while DS1267BE-050+ is in active production. The packaging differs (DS1267E-50+ uses standard packaging; DS1267BE-050+ is supplied in tubes), but electrical and mechanical parameters are identical.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical RoHS3 compliance and REACH unaffected status. No compliance-related restrictions apply to substitution.

Q: What is the wiper resistance specification?

A: DS1267E-50+ specifies 400Ω typical wiper resistance, while DS1267BE-050+ specifies 900Ω typical wiper resistance. Both values fall within acceptable operating parameters for the 50kΩ potentiometer configuration and do not affect functional substitution in standard applications.

Q: Is the 20-TSSOP package suitable for automated assembly?

A: Yes. The 20-TSSOP package is a standard surface-mount package suitable for automated pick-and-place assembly and reflow soldering processes.
