DS9034PC Equivalent & Substitute Parts

Part Overview

The DS9034PC is a nonvolatile static RAM (NV SRAM) module with integrated backup power management, manufactured by Analog Devices Inc./Maxim Integrated. This component belongs to the Memory integrated circuits category and features a 34-PowerCap™ Module package for surface mount applications. The DS9034PC is classified as obsolete, which necessitates identification of active equivalent parts for ongoing design requirements and procurement planning.

Substitute Part Grouping Explanation

Substitution of the DS9034PC is determined by strict equivalence across the following critical parameters:

• Manufacturer and Base Product Number: Both the main part and substitute must originate from Analog Devices Inc./Maxim Integrated and share the DS9034 base product number to ensure functional and electrical compatibility.
• Package and Form Factor: The 34-PowerCap™ Module package is the defining mechanical specification. Substitutes must use identical packaging to ensure compatibility with existing PCB layouts and mechanical assemblies.
• Functional Specification: Back-up management capability with lithium cell battery chemistry must be preserved.
• Operating Temperature Range: The 0°C ~ 70°C operating window must be maintained.
• Mounting Type: Surface mount configuration must be consistent.

The DS9034PC+ qualifies as a direct substitute based on full alignment with these parameters. The primary distinction is product status and compliance improvements.

Engineering Selection Recommendations

The DS9034PC+ is the direct equivalent substitute for the DS9034PC. Selection of the DS9034PC+ is based on the following engineering criteria:

• Product Status: The DS9034PC+ maintains active product status, ensuring continued manufacturer support, availability, and supply chain reliability. The DS9034PC is obsolete and subject to discontinuation.
• Regulatory Compliance: The DS9034PC+ achieves ROHS3 compliance, meeting current environmental and regulatory requirements. The DS9034PC is RoHS non-compliant.
• Moisture Sensitivity: The DS9034PC+ features MSL 1 (Unlimited), providing superior moisture tolerance compared to the DS9034PC (MSL 3, 168 Hours). This reduces handling and storage constraints.
• Functional Equivalence: Both parts maintain identical electrical function, operating temperature range, package form factor, and mounting type, ensuring direct substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can the DS9034PC+ be used as a direct replacement for the DS9034PC in existing designs?

A: Yes. The DS9034PC+ is electrically and mechanically equivalent to the DS9034PC. Both components share the same base product number (DS9034), package type (34-PowerCap™ Module), operating temperature range (0°C ~ 70°C), and functional specification (back-up management with lithium cell battery). No design changes are required for substitution.

Q: What are the key differences between the DS9034PC and DS9034PC+?

A: The primary differences are product status, regulatory compliance, and moisture sensitivity. The DS9034PC+ is an active product with ROHS3 compliance and MSL 1 rating, while the DS9034PC is obsolete, RoHS non-compliant, and carries MSL 3 rating. These differences do not affect electrical or mechanical compatibility.

Q: Why is the DS9034PC classified as obsolete?

A: The DS9034PC has been superseded by the DS9034PC+, which offers improved compliance and handling characteristics. Obsolete status indicates that the manufacturer no longer actively produces or supports this variant.

Q: Are there any packaging differences between these parts?

A: The DS9034PC+ is supplied in Tube packaging, while the DS9034PC packaging specification is not provided. Both parts use the identical 34-PowerCap™ Module case type. Verify packaging requirements for your procurement and assembly processes.

Q: What is the significance of the MSL rating difference?

A: MSL (Moisture Sensitivity Level) indicates the component's sensitivity to moisture during storage and handling. The DS9034PC+ (MSL 1, Unlimited) has no moisture-related storage time restrictions, while the DS9034PC (MSL 3, 168 Hours) requires controlled storage conditions and has a 168-hour floor life limit after moisture exposure. The DS9034PC+ provides greater flexibility in handling and storage.

Q: Are both parts subject to the same shipping restrictions?

A: Yes. Both the DS9034PC and DS9034PC+ are subject to ground shipment restrictions only, as specified by the manufacturer.
