40097BDM Equivalent & Substitute Parts

Part Overview

The 40097BDM is a bus driver logic component manufactured by Rochester Electronics, LLC, classified as a 2-function, 6-bit bus driver. This part is currently active in production status with 925 pieces available in new original inventory. The 40097BDM serves as a logic interface component for bus driving applications requiring multi-bit signal distribution and control.

Identification of equivalent and substitute parts becomes necessary when original inventory is depleted, when alternative sourcing is required for supply chain continuity, or when design flexibility permits the use of functionally compatible alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 40097BDM is based on alignment with the base product number 40097B, which establishes the functional and electrical equivalence class. The substitute part 40097BDMQB shares the same base product number, confirming compatibility at the functional level.

The substitution logic is determined by the following key parameters:

• Base Product Number Match: Both parts reference 40097B, establishing core functional equivalence
• Logic Category: Both components are classified as Logic category parts
• Functional Classification: Both serve bus driver and buffer functions within the logic component family
• Package Compatibility: The substitute part specifies 16-CDIP packaging with through-hole mounting, which is the physical implementation of the 40097B design

The 40097BDMQB is a parametric equivalent that implements the 40097B design through Fairchild Semiconductor, providing an alternative source for the same functional specification.

Parameter Comparison

Engineering Selection Recommendations

Selection between the 40097BDM and 40097BDMQB should be based on the following engineering criteria:

Product Status Alignment: Both parts maintain active product status, ensuring continued availability and manufacturer support for the functional specification.

Compliance Considerations: The 40097BDM carries REACH Affected status, while the 40097BDMQB is REACH Unaffected. Applications subject to REACH compliance requirements should evaluate the regulatory implications of each option. The 40097BDMQB is RoHS non-compliant, which may impact applications with RoHS compliance mandates.

Moisture Sensitivity: The 40097BDM has vendor-undefined MSL, while the 40097BDMQB specifies MSL 2A with a 4-week floor life. Applications requiring defined moisture handling procedures should account for the 40097BDMQB's specified sensitivity level.

Inventory Availability: The 40097BDM has 925 pieces in stock, while the 40097BDMQB has 1269 pieces available. Selection may be influenced by immediate availability requirements and supply chain continuity planning.

Base Product Equivalence: Both parts reference the 40097B base product number, confirming functional and electrical equivalence for bus driver and buffer applications.

Frequently Asked Questions (FAQ)

Q: What determines whether the 40097BDMQB can substitute for the 40097BDM?

A: Substitution is established through the shared base product number 40097B, which defines the functional specification for bus driver logic components. Both parts implement this specification and are classified as active products in the Logic category.

Q: Are there differences in electrical performance between these parts?

A: The 40097BDMQB provides specified electrical parameters including 3-state output capability, 3.2mA output high current, and 11.25mA output low current. The 40097BDM does not have these parameters specified in the available documentation. Applications requiring specific electrical performance characteristics should reference the complete datasheets for both parts.

Q: What is the significance of the different packaging specifications?

A: The 40097BDMQB specifies 16-CDIP through-hole packaging. The 40097BDM packaging is not specified in the available data. PCB layout and assembly process compatibility must be confirmed based on the actual packaging of the 40097BDM in use.

Q: How do the REACH and RoHS compliance statuses affect part selection?

A: The 40097BDM is REACH Affected, while the 40097BDMQB is REACH Unaffected. The 40097BDMQB is RoHS non-compliant. Applications with regulatory compliance requirements must evaluate these statuses against applicable standards and customer requirements.

Q: What is the moisture sensitivity difference between these parts?

A: The 40097BDM has vendor-undefined MSL, providing no specified moisture handling requirements. The 40097BDMQB specifies MSL 2A with a 4-week floor life, requiring controlled storage and handling procedures. Applications in high-humidity environments or with extended storage periods should account for these differences.

Q: Can both parts be used interchangeably in existing designs?

A: Both parts share the 40097B base product number and active status, establishing functional equivalence. Physical compatibility depends on the actual packaging of the 40097BDM and the 16-CDIP specification of the 40097BDMQB. Design documentation and PCB specifications must be reviewed to confirm mechanical compatibility.
