DS1267-010+ Digital Potentiometer Equivalent & Substitute Parts

Part Overview

The DS1267-010+ is a digital potentiometer IC manufactured by Analog Devices Inc./Maxim Integrated, designed for data acquisition applications requiring programmable resistance control. This 10kΩ dual-circuit device features 256 taps with serial interface control and is housed in a 14-DIP through-hole package.

The DS1267-010+ has reached obsolete product status. Identifying compatible substitute parts is essential for ongoing system support, design updates, and procurement continuity when original inventory becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1267-010+ is determined by strict equivalence across core electrical and functional parameters:

Critical Matching Parameters:

• Resistance value: 10kΩ
• Number of circuits: 2
• Number of taps: 256
• Interface: Serial
• Supply voltage: 5V
• Taper: Linear
• Temperature range: -40°C to 85°C
• Tolerance: ±20%
• Temperature coefficient: 750ppm/°C

The DS1267BE-010+ qualifies as a direct substitute because it maintains identical electrical specifications and functional characteristics. The primary difference is packaging format: the substitute transitions from through-hole (14-DIP) to surface-mount (20-TSSOP) technology, which affects board-level integration but not electrical performance or protocol compatibility.

Parameter Comparison

Engineering Selection Recommendations

The DS1267BE-010+ is the qualified substitute for the obsolete DS1267-010+. Both parts maintain identical electrical specifications, functional behavior, and regulatory compliance (ROHS3, REACH Unaffected, EAR99 classification).

Selection between these parts depends on board-level integration requirements:

DS1267-010+ (14-DIP Through-Hole): Use when existing PCB designs require through-hole mounting or when legacy board layouts cannot be modified.

DS1267BE-010+ (20-TSSOP Surface-Mount): Use for new designs, board revisions, or when surface-mount technology is preferred. This part carries active product status, ensuring long-term availability and manufacturing support.

The wiper resistance difference (400Ω vs. 900Ω) reflects typical manufacturing variation within the specified tolerance and does not affect functional compatibility in standard applications.

Frequently Asked Questions (FAQ)

Q: Can DS1267BE-010+ replace DS1267-010+ in existing designs?

A: Electrical and functional compatibility is complete. PCB integration requires modification due to package format change from 14-DIP through-hole to 20-TSSOP surface-mount. Schematic connections remain identical; layout and soldering methods differ.

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

A: The wiper resistance (400Ω vs. 900Ω) represents typical device-to-device variation within the ±20% tolerance specification. Both values fall within acceptable operating parameters and do not affect serial interface protocol or resistance control resolution.

Q: Why is DS1267-010+ listed as obsolete?

A: Obsolete status indicates the manufacturer has discontinued production. The DS1267BE-010+ represents the active product line continuation with identical electrical specifications.

Q: Are there compliance or certification differences?

A: Both parts carry identical regulatory status: ROHS3 Compliant, REACH Unaffected, and EAR99 classification. No compliance barriers exist for substitution.

Q: What packaging considerations apply to the substitute?

A: DS1267BE-010+ uses 20-TSSOP surface-mount packaging (0.173" width, 4.40mm) versus the original 14-DIP through-hole format (0.300" width, 7.62mm). Surface-mount assembly requires SMD soldering equipment and modified PCB footprints.
