Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS9034PCI is determined by strict adherence to the following parameters:

• Package Compatibility: Both the main part and substitute must use the 34-PowerCap™ Module package format
• Mounting Type: Surface mount configuration must be maintained
• Functional Equivalence: Back-up management and nonvolatile SRAM functionality must be preserved
• Battery Chemistry: Lithium cell battery chemistry must remain consistent
• Operating Temperature: The -40°C to 85°C operating range must be supported
• Base Product Number: Parts must share the DS9034 base product designation

The DS9034PCI+ meets all substitution criteria as a direct equivalent from the same manufacturer, sharing identical functional specifications and package requirements while offering improved product status and compliance characteristics.

Parameter Comparison

Engineering Selection Recommendations

The DS9034PCI+ is the direct substitute for the DS9034PCI. Both components share identical functional specifications, package geometry, and electrical operating parameters. The DS9034PCI+ offers significant advantages in product lifecycle status and regulatory compliance:

• Product Status: The DS9034PCI+ maintains active production status, ensuring long-term availability and supply chain stability compared to the obsolete DS9034PCI
• RoHS Compliance: The DS9034PCI+ achieves ROHS3 compliance, meeting current environmental and regulatory requirements
• Moisture Sensitivity: The DS9034PCI+ provides superior moisture handling characteristics with MSL 1 rating versus MSL 3, reducing risk during storage and assembly processes

For new designs and ongoing system support, the DS9034PCI+ is the appropriate selection. For legacy systems currently using the DS9034PCI, direct substitution with the DS9034PCI+ is electrically and mechanically compatible without design modification.

Frequently Asked Questions (FAQ)

Q: Can the DS9034PCI+ be used as a direct replacement for the DS9034PCI?

A: Yes. The DS9034PCI+ is a direct substitute. Both components share identical package geometry (34-PowerCap™ Module), mounting type (surface mount), functional specifications (nonvolatile SRAM with timekeeping and back-up management), battery chemistry (lithium cell), and operating temperature range (-40°C to 85°C). No circuit design changes are required.

Q: What are the key differences between DS9034PCI and DS9034PCI+?

A: The primary differences are product status, regulatory compliance, and moisture sensitivity. The DS9034PCI+ is in active production, ROHS3 compliant, and rated MSL 1 (unlimited moisture exposure), whereas the DS9034PCI is obsolete, RoHS non-compliant, and rated MSL 3 (168-hour moisture exposure limit).

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

A: No. Both components use the identical 34-PowerCap™ Module package with the same supplier device package designation. Pinout and mechanical dimensions are equivalent.

Q: Why is the DS9034PCI classified as obsolete?

A: The DS9034PCI has been superseded by the DS9034PCI+ in the manufacturer's product line. The DS9034PCI+ provides improved compliance characteristics and production status while maintaining full functional and mechanical compatibility.

Q: What does MSL 1 versus MSL 3 mean for component handling?

A: MSL (Moisture Sensitivity Level) indicates the maximum exposure time to moisture before component damage risk increases. MSL 1 (unlimited) allows indefinite storage under controlled conditions. MSL 3 (168 hours) requires component use within 168 hours of package opening under standard moisture conditions. The DS9034PCI+ offers superior handling flexibility.
