Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS2502P/T&R is determined by strict equivalence across the following critical parameters:

• Memory Interface: 1-Wire® protocol compatibility
• Memory Size & Organization: 1Kbit capacity with 128 x 8 organization
• Memory Technology: EPROM - OTP format
• Electrical Specifications: Supply voltage range 2.8V ~ 6V and operating temperature -40°C ~ 85°C
• Package Configuration: 6-TSOC surface mount with J-lead
• Base Product Number: DS2502 series designation

The substitute part DS2502P+T&R maintains identical electrical and mechanical specifications while differing only in packaging format (Cut Tape & Digi-Reel® versus the original packaging designation) and product status (Active versus Obsolete).

Parameter Comparison

Engineering Selection Recommendations

The DS2502P+T&R serves as a direct functional equivalent to the obsolete DS2502P/T&R. Selection between these parts should be based on the following criteria:

For New Designs or Compliance-Critical Applications: The DS2502P+T&R is the appropriate choice due to its Active product status and ROHS3 compliance certification. This part ensures regulatory alignment and long-term supply chain availability.

For Legacy System Maintenance: The DS2502P/T&R remains functionally interchangeable where existing inventory is available and RoHS non-compliance does not conflict with application requirements or regional regulations.

Availability Consideration: The DS2502P+T&R maintains significantly higher inventory levels (5617 Pcs) compared to the original part (888 Pcs), supporting sustained procurement for production and service applications.

Both parts share identical electrical performance, thermal operating range, and mechanical package specifications, ensuring direct pin-for-pin and functional compatibility in 1-Wire® EPROM memory applications.

Frequently Asked Questions (FAQ)

Q: Can DS2502P+T&R replace DS2502P/T&R in existing circuit designs?

A: Yes. Both parts are electrically and mechanically identical, sharing the same 1-Wire® interface, 1Kbit memory capacity, supply voltage range (2.8V ~ 6V), operating temperature range (-40°C ~ 85°C), and 6-TSOC package configuration. Direct substitution is functionally valid.

Q: What is the difference between DS2502P/T&R and DS2502P+T&R?

A: The primary differences are packaging format (original designation versus Cut Tape & Digi-Reel® format) and product lifecycle status (Obsolete versus Active). The DS2502P+T&R also carries ROHS3 compliance certification, whereas the original part is RoHS non-compliant.

Q: Why is the original DS2502P/T&R marked as obsolete?

A: Obsolete status indicates the part has been discontinued from active manufacturing by Analog Devices Inc./Maxim Integrated. The DS2502P+T&R represents the current active equivalent within the DS2502 product family.

Q: Are there any compatibility concerns when switching from DS2502P/T&R to DS2502P+T&R?

A: No compatibility concerns exist. Both parts implement identical 1-Wire® protocol specifications, memory organization (128 x 8), and electrical characteristics. Pin configuration and functional behavior are equivalent.

Q: Which part should be selected for new production?

A: The DS2502P+T&R should be selected for new production due to its Active status, superior inventory availability, and ROHS3 compliance certification. This ensures regulatory compliance and supply chain continuity.

Q: Is the 6-TSOC package configuration identical between both parts?

A: Yes. Both DS2502P/T&R and DS2502P+T&R utilize the same 6-TSOC surface mount package with J-lead configuration, ensuring mechanical and electrical compatibility on PCB assemblies.
