Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the NCP304LSQ46T1 is determined by strict equivalence across the following critical parameters:

• Single-channel voltage monitoring architecture
• 4.6V threshold voltage specification
• Push-pull, totem pole output topology
• Active low reset signal logic
• Industrial temperature range (-40°C to 85°C)
• Surface mount, SC-82A/SOT-343 package compatibility
• onsemi NCP304 base product family

The NCP304LSQ46T1G qualifies as a direct substitute based on identical electrical specifications, package configuration, and functional characteristics. The primary distinction is product status and compliance certification.

Parameter Comparison

Engineering Selection Recommendations

The NCP304LSQ46T1G is the direct equivalent substitute for the obsolete NCP304LSQ46T1. Both parts share identical electrical and mechanical specifications, including voltage threshold, output topology, reset logic, temperature range, and package configuration.

The NCP304LSQ46T1G offers the advantage of active product status, ensuring continued availability and manufacturing support. Additionally, the NCP304LSQ46T1G meets ROHS3 compliance requirements, whereas the original part is RoHS non-compliant. This compliance improvement may be relevant for applications subject to environmental or regulatory restrictions.

Both parts maintain REACH Unaffected status and EAR99 export classification. The substitute is available in Cut Tape (CT) packaging format, suitable for automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can NCP304LSQ46T1G be used as a direct replacement for NCP304LSQ46T1?

A: Yes. The NCP304LSQ46T1G is electrically and mechanically equivalent. Both parts feature identical voltage threshold (4.6V), output configuration (push-pull, totem pole), reset logic (active low), temperature range (-40°C to 85°C), and SC-82A/SOT-343 package specification.

Q: What is the primary difference between these two parts?

A: The NCP304LSQ46T1 is obsolete, while the NCP304LSQ46T1G maintains active product status. The substitute also provides ROHS3 compliance versus RoHS non-compliance in the original part.

Q: Are there any package or pinout differences?

A: No. Both parts use the SC-82A/SOT-343 package with SC-82AB supplier device package designation. Pinout and mechanical dimensions are identical.

Q: Is the NCP304LSQ46T1G available in different packaging formats?

A: The NCP304LSQ46T1G is available in Cut Tape (CT) format. Verify packaging requirements for your specific assembly process.

Q: Do these parts have the same operating temperature range?

A: Yes. Both parts operate across -40°C to 85°C (TA), suitable for industrial applications.

Q: Are there compliance or certification differences?

A: Both parts maintain REACH Unaffected status and EAR99 export classification. The NCP304LSQ46T1G provides ROHS3 compliance, which may be required for certain applications or markets.
