PI3B16861AE Bus Switch 10 x 1:1 Equivalent & Substitute Parts

Part Overview

The PI3B16861AE is a bus switch IC manufactured by Diodes Incorporated, designed for 10 x 1:1 switching applications in logic circuits. This component operates as a single-supply device with a voltage range of 3V to 3.6V and is housed in a 48-TSSOP package. The product is currently obsolete, making equivalent and substitute parts necessary for ongoing system support and new design implementations. Substitute parts must maintain identical circuit configuration, package form factor, and electrical operating parameters to ensure direct compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the PI3B16861AE are qualified based on the following critical parameters that determine functional and physical compatibility:

Circuit Configuration: All substitutes must maintain a 10 x 1:1 bus switch topology with 2 independent circuits to preserve signal routing and switching functionality.

Package Compatibility: All substitutes must use the 48-TFSOP (48-TSSOP) package with identical 0.240" (6.10mm) width to ensure PCB footprint compatibility and pin-to-pin correspondence.

Voltage Supply Range: Substitutes must operate within the specified single-supply voltage range. The PI3B16861AE operates at 3V to 3.6V. Substitute parts with extended voltage ranges (2.3V to 3.6V) are compatible as they encompass the original operating window.

Operating Temperature: All substitutes must support the -40°C to 85°C temperature range to maintain performance across the same environmental conditions.

Compliance Standards: All substitutes must maintain ROHS3 compliance, MSL Level 1 rating, and REACH Unaffected status to meet regulatory and environmental requirements.

The following Renesas Electronics Corporation parts meet these substitution criteria:

• QS3VH16861PAG (Last Time Buy status)
• QS3VH16861PAG8 (Active status)
• QS3VH16210PAG (Obsolete status)

Parameter Comparison

Engineering Selection Recommendations

QS3VH16861PAG8 is the primary recommended substitute. This part is manufactured by Renesas Electronics Corporation and maintains Active product status, ensuring long-term availability and continued manufacturing support. It provides identical electrical and mechanical specifications to the PI3B16861AE while offering an extended voltage supply range (2.3V to 3.6V) that encompasses the original operating window. The part is ROHS3 compliant, REACH unaffected, and carries MSL Level 1 rating, meeting all regulatory and environmental requirements.

QS3VH16861PAG serves as a secondary option with Last Time Buy status. This part is electrically and mechanically equivalent to QS3VH16861PAG8 but has limited availability due to its product lifecycle stage. Selection of this part should be based on inventory availability and project timeline requirements.

QS3VH16210PAG is functionally compatible but carries Obsolete product status. While it maintains the required 10 x 1:1 circuit configuration, 48-TSSOP package, and operating temperature range, its obsolete status limits its suitability for new designs or long-term production requirements.

Frequently Asked Questions (FAQ)

Q: Can QS3VH16861PAG8 be used as a direct replacement for PI3B16861AE?

A: Yes. QS3VH16861PAG8 maintains identical circuit configuration (10 x 1:1), package form factor (48-TSSOP), operating temperature range (-40°C to 85°C), and compliance certifications (ROHS3, REACH unaffected, MSL Level 1). The extended voltage supply range (2.3V to 3.6V) is compatible with the original 3V to 3.6V specification.

Q: What is the difference between QS3VH16861PAG and QS3VH16861PAG8?

A: Both parts are electrically and mechanically equivalent. The primary difference is product status: QS3VH16861PAG is Last Time Buy, while QS3VH16861PAG8 is Active. QS3VH16861PAG8 is recommended for new designs due to its active manufacturing status and extended availability.

Q: Is QS3VH16210PAG a suitable substitute?

A: QS3VH16210PAG meets the core substitution criteria: 10 x 1:1 circuit configuration, 48-TSSOP package, -40°C to 85°C operating temperature, and full compliance certifications. However, its Obsolete product status makes it unsuitable for new designs or applications requiring long-term component availability.

Q: Are there any voltage supply considerations when substituting these parts?

A: The PI3B16861AE operates at 3V to 3.6V. All recommended substitutes (QS3VH16861PAG, QS3VH16861PAG8, QS3VH16210PAG) operate at 2.3V to 3.6V. This extended range is fully compatible with the original specification and poses no compatibility issues.

Q: Do all substitute parts use the same PCB footprint?

A: Yes. All substitute parts use the 48-TFSOP package with 0.240" (6.10mm) width, ensuring identical PCB footprint compatibility and pin-to-pin correspondence with the PI3B16861AE.

Q: What compliance certifications apply to these substitute parts?

A: All substitute parts maintain ROHS3 compliance, REACH Unaffected status, and MSL Level 1 (Unlimited) rating, matching the original PI3B16861AE specifications.
