Key Parameters

Substitute Part Grouping Explanation

Substitution for the DS2502P-E64 is determined by strict equivalence across the following critical parameters:

• Memory Capacity & Organization: 1Kbit capacity with 128 x 8 organization
• Memory Interface: 1-Wire® protocol compatibility
• Electrical Specifications: Supply voltage range 2.8V ~ 6V and operating temperature range -40°C ~ 85°C
• Physical Package: 6-TSOC surface mount package with J-Lead configuration
• Memory Technology: EPROM - OTP (One-Time Programmable) non-volatile memory

The substitute part DS2502P-E64+ meets all these criteria and maintains full functional and electrical compatibility with the original DS2502P-E64.

Parameter Comparison

Engineering Selection Recommendations

The DS2502P-E64+ is the direct substitute for the obsolete DS2502P-E64. Both parts share identical electrical and functional specifications, ensuring drop-in compatibility in existing circuit designs.

The DS2502P-E64+ offers the additional advantage of active product status, ensuring continued availability and supply chain support. The substitute part also achieves ROHS3 compliance, whereas the original DS2502P-E64 is RoHS non-compliant. Both parts maintain equivalent moisture sensitivity levels and regulatory classifications (REACH Unaffected, ECCN EAR99).

For new designs or production transitions, the DS2502P-E64+ is the appropriate selection. For legacy system maintenance requiring the original DS2502P-E64, the substitute provides full functional equivalence with improved compliance status.

Frequently Asked Questions (FAQ)

Q: Can DS2502P-E64+ be used as a direct replacement for DS2502P-E64?

A: Yes. The DS2502P-E64+ is a direct substitute with identical memory capacity (1Kbit), organization (128 x 8), interface (1-Wire®), electrical specifications (2.8V ~ 6V supply, -40°C ~ 85°C operating temperature), and physical package (6-TSOC). No circuit modifications are required.

Q: What is the primary difference between DS2502P-E64 and DS2502P-E64+?

A: The DS2502P-E64+ is the active production variant with ROHS3 compliance, while the DS2502P-E64 is obsolete and RoHS non-compliant. Functionally and electrically, both parts are equivalent.

Q: Are there any packaging differences between these parts?

A: Both parts use the same 6-TSOC surface mount package with J-Lead configuration. The DS2502P-E64+ is supplied in Tube packaging, while the original DS2502P-E64 packaging specification is not detailed. The physical component remains identical.

Q: What is the 1-Wire® interface compatibility?

A: Both parts implement the 1-Wire® protocol for memory access. The interface specifications are identical, ensuring protocol-level compatibility in systems designed for DS2502P-E64 operation.

Q: Are there supply voltage or temperature rating differences?

A: No. Both parts operate across the identical supply voltage range (2.8V ~ 6V) and temperature range (-40°C ~ 85°C). Electrical operating conditions are fully equivalent.
