DS2505P Equivalent & Substitute Parts

Part Overview

The DS2505P is a 16Kbit EPROM with 1-Wire® interface in a 6-TSOC surface mount package, manufactured by Analog Devices Inc./Maxim Integrated. This non-volatile memory device features a 15 µs access time and operates across the industrial temperature range of -40°C to 85°C. The DS2505P is classified as obsolete, making identification of compatible substitutes essential for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the DS2505P is determined by strict equivalence across the following critical parameters:

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

The DS2505P+ meets all these criteria and is identified as a direct substitute. The primary distinction between these parts is product status and compliance certification, not functional or electrical parameters.

Parameter Comparison

Engineering Selection Recommendations

The DS2505P+ is the direct functional equivalent of the DS2505P across all electrical and mechanical parameters. Selection between these parts should be based on the following criteria:

For new designs and systems requiring regulatory compliance, the DS2505P+ is the appropriate choice due to its Active product status and ROHS3 compliance certification. Both parts maintain identical functional specifications including 16Kbit capacity, 1-Wire® interface, 15 µs access time, and 6-TSOC packaging.

For legacy system maintenance where the original DS2505P is specified, the DS2505P+ provides functional continuity without design modification, as all critical parameters remain unchanged. The difference in RoHS compliance reflects manufacturing process updates rather than functional divergence.

Frequently Asked Questions (FAQ)

Q: Can DS2505P+ be used as a direct replacement for DS2505P in existing designs?

A: Yes. The DS2505P+ is functionally equivalent across all electrical and mechanical parameters. No circuit modifications are required. Both parts feature identical 16Kbit capacity, 1-Wire® interface, 15 µs access time, and 6-TSOC packaging.

Q: What is the difference between DS2505P and DS2505P+?

A: The primary differences are product status and compliance certification. The DS2505P is classified as obsolete, while the DS2505P+ is active. The DS2505P+ meets ROHS3 compliance, whereas the DS2505P is RoHS non-compliant. All functional specifications remain identical.

Q: Are there any package or pinout differences between these parts?

A: No. Both parts use the 6-TSOC package with 6-SMD, J-Lead configuration. Pinout and mechanical dimensions are identical, enabling direct board-level substitution.

Q: What is the moisture sensitivity level for these parts?

A: Both the DS2505P and DS2505P+ have a Moisture Sensitivity Level (MSL) of 1, indicating unlimited shelf life without moisture control requirements.

Q: Which part should be selected for new production?

A: The DS2505P+ should be selected for new production due to its active product status and ROHS3 compliance certification. This ensures long-term availability and regulatory alignment.
