Substitute Part Grouping Explanation

Substitution eligibility for the DS2506S is determined by strict equivalence across the following critical parameters:

• Memory Capacity & Organization: 64Kbit capacity with 64K x 1 organization
• Memory Interface Protocol: 1-Wire® interface compatibility
• Access Time: 2 µs specification
• Package Type: 8-SOIC surface mount form factor with 0.209" (5.30mm) width
• Operating Temperature Range: -40°C to 85°C
• Non-Volatile Memory Technology: EPROM - OTP classification
• Compliance Standards: ROHS3 compliance and MSL Level 1 rating

The DS2506S+ qualifies as a direct substitute based on identical electrical specifications, package dimensions, and interface protocol. The primary distinction is product status and packaging format.

Parameter Comparison

Engineering Selection Recommendations

The DS2506S+ is the direct equivalent substitute for the DS2506S. Both components share identical electrical specifications, memory capacity, interface protocol, and package dimensions. The DS2506S+ maintains active product status with Analog Devices Inc./Maxim Integrated, ensuring ongoing availability and support.

Selection of the DS2506S+ is appropriate for new designs, production continuity, and replacement applications. Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for industrial and commercial applications.

The DS2506S+ is supplied in tube packaging format, which may differ from original DS2506S procurement specifications. Verify packaging compatibility with assembly and handling procedures before implementation.
