NBVSPA042LNHTAG Equivalent & Substitute Parts

Part Overview

The NBVSPA042LNHTAG is a VCXO (Voltage Controlled Crystal Oscillator) IC manufactured by onsemi, operating at 74.25MHz in a 6-CLCC surface mount package. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing production and maintenance applications. The 74.25MHz frequency and 6-CLCC package form factor are critical parameters for determining functional equivalence in clock/timing applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the NBVSPA042LNHTAG is determined by the following critical parameters:

• Frequency Match: 74.25MHz operation is mandatory for clock/timing circuit compatibility
• Package Compatibility: 6-CLCC (7x5) surface mount package ensures mechanical and electrical fit
• Voltage Supply Range: The substitute must operate within or encompass the original supply voltage specification
• Current Supply: The substitute current rating must be compatible with circuit design requirements
• Operating Temperature Range: Must support the -40°C to 85°C operating window
• Mounting Type: Surface mount requirement must be maintained

The 8N3SV76EC-0168CDI8 from Renesas Electronics Corporation meets these substitution criteria through identical frequency, package form factor, and operating temperature specifications.

Parameter Comparison

Engineering Selection Recommendations

The 8N3SV76EC-0168CDI8 is a direct functional substitute for the obsolete NBVSPA042LNHTAG based on the following factors:

• Identical Frequency and Package: Both components operate at 74.25MHz in 6-CLCC (7x5) surface mount packages, ensuring pin-for-pin compatibility and circuit board fit
• Matching Operating Temperature Range: Both support -40°C to 85°C operation, maintaining thermal performance specifications
• Overlapping Supply Voltage: The substitute's 3.135V ~ 3.465V range overlaps with the original 2.97V ~ 3.63V specification, ensuring compatibility with existing power supply designs
• Active Product Status: The Renesas component is actively manufactured and available, providing supply chain continuity for the obsolete onsemi part
• Equivalent Compliance: Both components share identical MSL ratings and REACH compliance status, maintaining environmental and reliability standards

The higher current supply specification (130 mA vs. 75 mA) in the substitute requires verification that the circuit power supply can accommodate this increased demand, though this does not preclude substitution.

Frequently Asked Questions (FAQ)

Q: Can the 8N3SV76EC-0168CDI8 be used as a direct replacement for the NBVSPA042LNHTAG?

A: Yes. Both components are 74.25MHz VCXO oscillators in identical 6-CLCC (7x5) surface mount packages with matching operating temperature ranges and MSL ratings. The substitute is functionally equivalent for clock/timing applications.

Q: What is the impact of the higher current supply specification in the substitute part?

A: The substitute draws 130 mA compared to the original 75 mA. Circuit power supply design must accommodate this increased current draw. If the existing power supply is marginal, additional analysis or power supply redesign may be necessary.

Q: Are there voltage supply compatibility concerns?

A: The substitute's supply voltage range (3.135V ~ 3.465V) overlaps with the original specification (2.97V ~ 3.63V). Both components will operate correctly within the overlapping range of 3.135V ~ 3.63V. Verify that the circuit power supply operates within this window.

Q: Is the 6-CLCC package identical between both parts?

A: Yes. Both components use the 6-CLCC (7x5) surface mount package with identical mechanical and electrical characteristics, ensuring direct board-level compatibility without layout modifications.

Q: What is the product status difference between these components?

A: The NBVSPA042LNHTAG is obsolete, while the 8N3SV76EC-0168CDI8 is actively manufactured by Renesas Electronics Corporation. This ensures long-term availability and supply chain reliability for the substitute.
