BU4094BCFV-E2 Equivalent & Substitute Parts

Part Overview

The BU4094BCFV-E2 is an 8-bit shift register logic IC manufactured by Rohm Semiconductor in a 16-SSOP surface mount package. This device converts serial input data to parallel output format with tri-state output capability, operating across a 3V to 18V supply voltage range. The part is active in production status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified when equivalent functional specifications, electrical parameters, and package compatibility exist across different manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BU4094BCFV-E2 is determined by the following criteria:

Core Functional Requirements:

• Logic type: Shift Register
• Bit configuration: 8-bit, single element
• Function: Serial to Parallel conversion
• Output configuration: Tri-State

Electrical Compatibility:

• Supply voltage range: 3V ~ 18V (minimum requirement)
• Operating temperature range must support the application environment

Physical Compatibility:

• Package type: 16-pin SSOP or TSSOP variants with 0.173" (4.40mm) width
• Surface mount configuration

Compliance Requirements:

• ROHS3 compliance mandatory
• Moisture sensitivity level 1 (unlimited)

Parts meeting all these criteria are classified as direct substitutes. Variations in operating temperature range, packaging format (CT vs. TR), or additional qualifications (such as automotive grade) do not disqualify substitution but may indicate enhanced performance or application-specific suitability.

Parameter Comparison

Engineering Selection Recommendations

NLV14094BDTR2G (onsemi) is classified as an upgrade substitute. This part maintains all core functional and electrical parameters while offering an extended operating temperature range (-55°C to 125°C versus -40°C to 85°C) and automotive-grade qualification under AEC-Q100. The packaging format is 16-TSSOP in tape and reel configuration. Selection of this part is appropriate for applications requiring automotive compliance or extended temperature operation.

CD4094BPWR (Texas Instruments) is classified as a similar substitute. This part matches all functional specifications and electrical parameters with an extended operating temperature range (-55°C to 125°C). The packaging is 16-TSSOP in cut tape format. Both the Rohm BU4094BCFV-E2 and Texas Instruments CD4094BPWR share the 4000B series designation, indicating design compatibility within this logic family.

All three parts maintain active production status, ROHS3 compliance, and unlimited moisture sensitivity rating. Selection between these options depends on packaging preference (tape and reel versus cut tape), temperature requirements, and automotive qualification needs.

Frequently Asked Questions (FAQ)

Q: Can NLV14094BDTR2G replace BU4094BCFV-E2 in existing designs?

A: Yes. Both parts are 8-bit shift registers with tri-state outputs, identical supply voltage ranges (3V ~ 18V), and compatible 16-pin packages with 4.40mm width. The NLV14094BDTR2G offers extended temperature range and automotive qualification, making it suitable for applications requiring these specifications.

Q: What is the difference between 16-LSSOP and 16-TSSOP packages?

A: Both are 16-pin surface mount packages with 0.173" (4.40mm) width. LSSOP denotes Low-profile Shrink Small Outline Package, while TSSOP denotes Thin Shrink Small Outline Package. The functional pinout and electrical performance are equivalent for this shift register application.

Q: Does the automotive grade of NLV14094BDTR2G affect compatibility?

A: No. Automotive grade and AEC-Q100 qualification indicate enhanced reliability testing and suitability for automotive environments. These qualifications do not alter the functional or electrical compatibility with standard-grade equivalents.

Q: Are there packaging format considerations when substituting?

A: Yes. The BU4094BCFV-E2 is supplied in cut tape format, while NLV14094BDTR2G is supplied in tape and reel format. CD4094BPWR is available in cut tape format. Verify that your assembly process accommodates the selected packaging format.

Q: Do all three parts share the same pinout?

A: Yes. All three parts are 8-bit shift registers with identical functional pinouts, enabling direct pin-for-pin substitution in circuit designs.

Q: What compliance certifications apply to all substitute options?

A: All three parts are ROHS3 compliant, REACH unaffected, and classified under ECCN EAR99 with HTSUS code 8542.39.0001. Moisture sensitivity level is 1 (unlimited) for all options.
