Engineering Selection Recommendations

The MAX1259CWE+ serves as the primary substitute for the obsolete DS1259SN. Key selection factors include:

Product Status Consideration: The DS1259SN is obsolete, while MAX1259CWE+ maintains active product status with 693 pieces in current inventory. This ensures long-term availability and supply chain continuity.

Compliance Advantage: MAX1259CWE+ achieves ROHS3 compliance, whereas the DS1259SN is RoHS non-compliant. For applications subject to RoHS regulations, MAX1259CWE+ provides regulatory alignment.

Packaging and Thermal Compatibility: Both parts share identical 16-SOIC package dimensions and operating temperature specifications (0°C ~ 70°C), ensuring direct PCB layout compatibility and thermal performance equivalence.

Supply Chain Status: With 693 pieces in stock, MAX1259CWE+ provides immediate availability for production and development applications.

Frequently Asked Questions (FAQ)

Q: Can MAX1259CWE+ be used as a direct replacement for DS1259SN in existing designs?

A: Yes. Both parts share identical package geometry (16-SOIC, 0.295" × 7.50mm), mounting type (surface mount), and operating temperature range (0°C ~ 70°C). PCB footprints and thermal characteristics are equivalent.

Q: What is the primary difference between DS1259SN and MAX1259CWE+?

A: The DS1259SN is obsolete with RoHS non-compliant status, while MAX1259CWE+ is an active product with ROHS3 compliance. Both maintain identical electrical and mechanical specifications for power management applications.

Q: Are there any packaging format differences?

A: The DS1259SN is supplied in standard packaging, while MAX1259CWE+ is supplied in tube packaging. Both use the same 16-SOIC component package. Tube packaging does not affect electrical or mechanical compatibility.

Q: What compliance certifications apply to both parts?

A: Both DS1259SN and MAX1259CWE+ maintain REACH Unaffected status and share identical ECCN (EAR99) and HTSUS (8542.39.0001) classifications. MAX1259CWE+ additionally provides ROHS3 compliance.

Q: Is the operating temperature range identical?

A: Yes. Both parts operate within 0°C ~ 70°C (TA) specification, ensuring thermal performance equivalence in equivalent operating environments.
