Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DS1830 is determined by strict equivalence across the following critical parameters:

• Number of voltages monitored: 3 channels
• Voltage threshold specification: 5V
• Output type: Open Drain or Open Collector
• Reset configuration: Active Low
• Reset timeout range: 10ms, 20ms, 50ms minimum
• Package type: 8-DIP (0.300", 7.62mm)
• Operating temperature range: -40°C ~ 85°C
• Mounting configuration: Through Hole

Parts meeting all these criteria are classified as direct substitutes. The DS1830+ meets all electrical and mechanical parameters required for direct substitution with the DS1830.

Parameter Comparison

Engineering Selection Recommendations

The DS1830+ is a direct electrical and mechanical equivalent to the DS1830. Both parts share identical functional specifications across all monitored parameters: 3-channel voltage supervision, 5V threshold, open drain/open collector output, active low reset, and 8-DIP through-hole packaging.

The primary distinction between these parts is product status and regulatory compliance. The DS1830 is obsolete, while the DS1830+ maintains active product status from the manufacturer. Additionally, the DS1830+ is ROHS3 compliant, whereas the DS1830 is RoHS non-compliant. Both parts maintain REACH Unaffected status and identical moisture sensitivity levels.

For new designs or production continuity, the DS1830+ is the appropriate selection due to its active availability and enhanced regulatory compliance posture.

Frequently Asked Questions (FAQ)

Q: Can the DS1830+ be used as a direct replacement for the DS1830 in existing designs?

A: Yes. The DS1830+ is electrically and mechanically equivalent to the DS1830. All functional parameters, including voltage monitoring channels, threshold specifications, output configuration, reset logic, timeout values, operating temperature range, and 8-DIP package dimensions are identical between the two parts.

Q: What is the primary reason to transition from DS1830 to DS1830+?

A: The DS1830 is classified as obsolete product status, creating supply chain risk for ongoing production. The DS1830+ is an active product with equivalent specifications and improved regulatory compliance (ROHS3 compliant), making it the recommended choice for design continuity.

Q: Are there any package or pinout differences between DS1830 and DS1830+?

A: No. Both parts utilize the same 8-DIP (0.300", 7.62mm) through-hole package with identical pinout and mechanical dimensions. Direct PCB substitution is supported without layout modifications.

Q: What compliance certifications apply to these parts?

A: Both DS1830 and DS1830+ maintain REACH Unaffected status and Moisture Sensitivity Level 1 (Unlimited). The DS1830+ additionally carries ROHS3 compliance, while the DS1830 is RoHS non-compliant.

Q: Are there inventory considerations when selecting between these parts?

A: Current inventory shows 887 pieces of DS1830 (obsolete status) and 941 pieces of DS1830+ (active status) available. For new procurement, the DS1830+ is the recommended selection due to active product status and ongoing manufacturer support.
