Key Parameters

Substitute Part Grouping Explanation

Substitution for the DS1077LZ-50+ is determined by strict equivalence across the following critical parameters:

• Frequency Range: 6.09kHz ~ 50MHz
• Supply Voltage: 2.7V ~ 3.6V
• Supply Current: 20 mA maximum
• Operating Temperature Range: -40°C ~ 85°C
• Package Type: 8-SOIC surface-mount configuration
• Functional Classification: Dual fixed-frequency oscillator
• Compliance: ROHS3 compliance and MSL Level 1

A substitute part must match all of these parameters to ensure functional and mechanical compatibility within existing designs. Deviations in any parameter category disqualify a part from direct substitution.

Parameter Comparison

Engineering Selection Recommendations

The DS1077LZ-50+ is classified as an obsolete product. When sourcing this component, the following factors apply:

• Compliance Verification: Confirm ROHS3 compliance status for your application's regulatory requirements.
• Moisture Handling: MSL Level 1 rating indicates unlimited shelf life without moisture sensitivity concerns, simplifying storage and handling protocols.
• Package Compatibility: The 8-SOIC form factor is standard for surface-mount assembly. Verify PCB footprint alignment with the specified 0.154" (3.90mm) width.
• Supply Chain Status: Given obsolescence, inventory availability may be limited. Current stock levels should be confirmed with suppliers before design finalization.

Frequently Asked Questions (FAQ)

Q: What makes a part a valid substitute for the DS1077LZ-50+?

A: A substitute must match all critical parameters: frequency range (6.09kHz ~ 50MHz), supply voltage (2.7V ~ 3.6V), supply current (20 mA), operating temperature (-40°C ~ 85°C), 8-SOIC package type, and dual fixed-frequency oscillator functionality. Any deviation disqualifies the part from direct substitution.

Q: Can I use a different package type if the electrical specifications match?

A: No. The 8-SOIC package is a mechanical requirement for PCB compatibility. Alternative packages require circuit board redesign and are not considered direct substitutes.

Q: Why is product status important for substitution?

A: Obsolete status indicates the manufacturer has discontinued production. This affects long-term availability and may influence design decisions regarding component lifecycle management and inventory planning.

Q: What does MSL Level 1 mean for handling?

A: MSL Level 1 means the component has unlimited shelf life and requires no special moisture control measures during storage or handling, simplifying logistics and reducing handling costs.

Q: Are there any compliance considerations I should address?

A: ROHS3 compliance is confirmed for this component. Verify that your application and regional regulations align with ROHS3 requirements before final component selection.
