Key Parameters

Substitute Part Grouping Explanation

The 7SB384DFT2G qualifies as a parametric equivalent to the 7SB385DFT2G based on the following critical substitution criteria:

Matching Parameters:

• Identical circuit configuration: 1 x 1:1 bus switch topology
• Identical independent circuits count: 1
• Identical voltage supply source: Single Supply
• Identical supply voltage range: 4V ~ 5.5V
• Identical operating temperature range: -55°C ~ 125°C
• Identical mounting type: Surface Mount
• Identical package designation: 5-TSSOP, SC-70-5, SOT-353
• Identical supplier device package: SC-88A (SC-70-5/SOT-353)
• Identical RoHS compliance: ROHS3 Compliant
• Identical MSL rating: 1 (Unlimited)
• Identical REACH status: REACH Unaffected

Both parts are manufactured by onsemi and share the same functional classification as Logic bus switches. The substitution is valid for applications requiring identical electrical performance and mechanical compatibility within the specified parameter set.

Parameter Comparison

Engineering Selection Recommendations

Both the 7SB385DFT2G and 7SB384DFT2G are Last Time Buy components from onsemi, indicating limited future availability. Selection between these parts should be based on current inventory status and supply chain requirements.

The 7SB384DFT2G currently maintains higher inventory availability (3895 Pcs) compared to the 7SB385DFT2G (3400 Pcs), making it the preferred choice for new production orders and long-term stock planning.

Both parts meet ROHS3 compliance and REACH requirements, ensuring regulatory compatibility for applications subject to environmental and hazardous substance restrictions. The MSL 1 rating indicates unlimited shelf life under standard storage conditions, eliminating moisture-related constraints for component handling and storage.

The identical electrical specifications, thermal operating range, and package configuration ensure direct functional interchangeability in existing circuit designs without requiring PCB layout modifications or design revalidation.

Frequently Asked Questions (FAQ)

Q: Can the 7SB384DFT2G replace the 7SB385DFT2G in existing designs?

A: Yes. Both parts are parametric equivalents with identical circuit configuration (1 x 1:1), supply voltage range (4V ~ 5.5V), operating temperature range (-55°C ~ 125°C), and package designation (5-TSSOP, SC-70-5, SOT-353). Direct substitution is valid without design modifications.

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

A: No. Both parts use the identical 5-TSSOP (SC-70-5/SOT-353) package with SC-88A supplier designation. Pinout and mechanical dimensions are identical, enabling direct PCB compatibility.

Q: What is the significance of the Last Time Buy status?

A: Last Time Buy status indicates that onsemi has discontinued or will discontinue production of these parts. Existing inventory represents the final available supply. Long-term production requirements should be addressed through alternative component selection or accelerated procurement of available stock.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the 7SB385DFT2G and 7SB384DFT2G are ROHS3 compliant and REACH unaffected, meeting identical regulatory requirements for environmental and hazardous substance restrictions.

Q: What is the MSL 1 rating, and does it affect component handling?

A: MSL 1 (Unlimited) indicates the component has unlimited shelf life under standard storage conditions. No special moisture control or baking procedures are required prior to assembly, simplifying inventory management and component handling.
