Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS1267-010 is determined by strict equivalence across core electrical and functional parameters. The substitute part DS1267BE-010+ maintains identical specifications for resistance value, circuit count, tap resolution, serial interface protocol, supply voltage, taper characteristic, operating temperature range, tolerance, temperature coefficient, and cascade pin functionality. Both parts share the same base product number (DS1267) and are manufactured by the same supplier.

The primary distinction between the main part and substitute lies in packaging format and product lifecycle status. The DS1267-010 uses through-hole mounting (14-DIP), while DS1267BE-010+ employs surface-mount technology (20-TSSOP). This packaging difference necessitates circuit board redesign and assembly process modification but does not affect electrical performance or functional compatibility at the component level.

Parameter Comparison

Engineering Selection Recommendations

The DS1267BE-010+ serves as the active production equivalent for the obsolete DS1267-010. Selection of DS1267BE-010+ is appropriate for new designs and systems requiring ongoing component availability. This substitute maintains full electrical and functional compatibility while offering ROHS3 compliance, addressing regulatory requirements not met by the original part.

For legacy systems currently using DS1267-010 in through-hole configuration, direct board-level substitution requires circuit redesign to accommodate the 20-TSSOP surface-mount package. The wiper resistance difference (400Ω versus 900Ω) must be evaluated within the context of specific circuit application requirements.

Frequently Asked Questions (FAQ)

Q: Can DS1267BE-010+ replace DS1267-010 without circuit modification?

A: Electrical and functional compatibility is maintained. However, packaging differences (14-DIP through-hole versus 20-TSSOP surface-mount) require circuit board redesign and assembly process changes.

Q: What is the significance of the wiper resistance difference?

A: The DS1267-010 specifies 400Ω typical wiper resistance, while DS1267BE-010+ specifies 900Ω. This parameter must be evaluated within the specific application circuit to determine if the difference affects system performance.

Q: Why is DS1267-010 classified as obsolete?

A: Product status reflects manufacturer lifecycle decisions. DS1267BE-010+ represents the active production alternative from the same manufacturer.

Q: Does RoHS compliance affect electrical performance?

A: RoHS compliance reflects manufacturing process and material composition changes but does not alter electrical specifications or functional behavior of the component.

Q: Are both parts pin-compatible?

A: No. DS1267-010 uses 14-pin DIP configuration while DS1267BE-010+ uses 20-pin TSSOP configuration. Pin assignments differ and require schematic and layout redesign.

Q: What is the cascade pin feature?

A: Both parts include cascade pin functionality, enabling series connection of multiple digital potentiometer circuits for extended resolution or independent control of additional resistance networks.
