Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS2505P/T&R is determined by strict equivalence across the following parameters:

• Memory capacity: 16Kbit
• Memory organization: 16K x 1
• Interface protocol: 1-Wire®
• Access time: 15 µs
• Operating temperature range: -40°C ~ 85°C
• Package type: 6-TSOC (6-SMD, J-Lead)
• Mounting configuration: Surface Mount

The DS2505P+T&R qualifies as a direct substitute based on identical electrical specifications and mechanical compatibility. The primary distinction between the main part and substitute is packaging format and product status.

Parameter Comparison

Engineering Selection Recommendations

The DS2505P+T&R is the direct functional equivalent of the DS2505P/T&R. Selection between these parts should be based on the following criteria:

• Product Status: The DS2505P+T&R maintains active product status, ensuring long-term availability and manufacturer support. The DS2505P/T&R is obsolete and subject to discontinuation.
• Regulatory Compliance: The DS2505P+T&R is ROHS3 compliant, meeting current environmental and regulatory requirements. The DS2505P/T&R is RoHS non-compliant.
• Packaging and Supply: The DS2505P+T&R is available in Cut Tape and Digi-Reel® formats with significantly higher inventory levels (2238 Pcs vs. 943 Pcs).
• Electrical and Mechanical Compatibility: Both parts are electrically and mechanically identical, with no design modifications required for substitution.

For new designs and production continuity, the DS2505P+T&R is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Are the DS2505P/T&R and DS2505P+T&R electrically interchangeable?

A: Yes. Both parts share identical electrical specifications, including 16Kbit memory capacity, 1-Wire® interface, 15 µs access time, and -40°C ~ 85°C operating temperature range.

Q: What is the difference between the T&R and +T&R packaging designations?

A: T&R indicates tube packaging, while +T&R indicates Cut Tape and Digi-Reel® packaging formats. Both are surface mount compatible with the 6-TSOC package specification.

Q: Can the DS2505P+T&R be used as a direct replacement in existing PCB designs?

A: Yes. The DS2505P+T&R is mechanically and electrically identical to the DS2505P/T&R. No PCB modifications or design changes are required.

Q: Why is the DS2505P/T&R classified as obsolete?

A: Product obsolescence is determined by the manufacturer. The DS2505P+T&R remains in active production and is the recommended alternative for ongoing applications.

Q: Are there RoHS compliance differences between these parts?

A: Yes. The DS2505P/T&R is RoHS non-compliant, while the DS2505P+T&R is ROHS3 compliant. For applications requiring RoHS compliance, the DS2505P+T&R is the required selection.

Q: What is the 1-Wire® interface?

A: 1-Wire® is a proprietary interface protocol developed by Maxim Integrated that enables communication over a single data line plus ground. Both parts implement this interface identically.
