Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS9034PCX is determined by strict alignment across the following critical parameters:

• Base Product Number: Both parts must share the DS9034 base designation
• Function: Back-up management capability must be maintained
• Battery Chemistry: Lithium cell technology must be preserved
• Operating Temperature Range: 0°C ~ 70°C compatibility required
• Mounting Type: Surface mount configuration must be identical
• Package / Case: 34-PowerCap™ Module form factor must match
• Manufacturer: Analog Devices Inc./Maxim Integrated

The DS9034PCX+ qualifies as a direct substitute based on full alignment across all critical electrical and mechanical parameters.

Parameter Comparison

Engineering Selection Recommendations

The DS9034PCX+ is the direct substitute for the obsolete DS9034PCX. Both parts maintain identical electrical and mechanical specifications across all critical parameters including function, battery chemistry, operating temperature range, mounting type, and package configuration.

The DS9034PCX+ offers improved compliance status: it is ROHS3 compliant compared to the non-compliant DS9034PCX, and features superior moisture sensitivity characteristics (MSL 1 with unlimited storage versus MSL 3 with 168-hour limitation). The DS9034PCX+ is currently in active production status, ensuring ongoing availability for component procurement and system support.

Frequently Asked Questions (FAQ)

Q: Can the DS9034PCX+ be used as a direct replacement for the DS9034PCX?

A: Yes. The DS9034PCX+ is a direct substitute. Both parts share identical functional specifications, battery chemistry, operating temperature range, mounting type, and 34-PowerCap™ Module package configuration.

Q: What is the primary difference between these two parts?

A: The DS9034PCX+ is the active production variant with improved compliance status (ROHS3 compliant versus non-compliant) and superior moisture sensitivity characteristics (MSL 1 versus MSL 3). The DS9034PCX is obsolete.

Q: Are there any compatibility concerns when substituting the DS9034PCX+ for the DS9034PCX?

A: No compatibility concerns exist. The parts are electrically and mechanically equivalent across all specified parameters.

Q: What does the MSL rating difference mean for handling and storage?

A: The DS9034PCX+ (MSL 1) has unlimited moisture sensitivity storage capability, while the DS9034PCX (MSL 3) requires storage within 168 hours of moisture exposure. The DS9034PCX+ offers more flexible handling and storage conditions.

Q: Is the DS9034PCX+ available in the same packaging as the DS9034PCX?

A: Yes. Both parts use the 34-PowerCap™ Module package configuration. The DS9034PCX+ is supplied in tube packaging.
