Key Parameters

Substitute Part Grouping Explanation

Substitution of the LTS 6-NP/SP2 current transducer is determined by alignment of the following critical electrical and mechanical parameters:

Primary Substitution Criteria:

• Current sensing capacity of 6A
• Single channel configuration
• Closed-loop sensor topology
• Ratiometric voltage output
• Frequency response DC to 200kHz
• Supply voltage range 4.75V to 5.25V
• Operating temperature range -40°C to 85°C
• Through-hole mounting configuration

Secondary Compatibility Factors:

• Linearity specification ±0.1%
• Accuracy tolerance (±0.2% preferred, ±0.7% acceptable with application review)
• Response time performance
• Active product status for ongoing availability

The substitute part T60404N4647X663 from VACUUMSCHMELZE meets the primary substitution criteria across all critical electrical parameters and maintains compatibility with the original application requirements.

Parameter Comparison

Engineering Selection Recommendations

The T60404N4647X663 current sensor from VACUUMSCHMELZE is electrically compatible with the LTS 6-NP/SP2 across all critical measurement parameters. Both devices operate at identical current sensing capacity (6A), frequency range (DC to 200kHz), supply voltage (4.75V to 5.25V), and operating temperature (-40°C to 85°C).

Electrical Compatibility: The substitute part maintains ±0.1% linearity matching the original specification. The accuracy specification of ±0.7% on the substitute is wider than the original ±0.2%, which must be evaluated against application tolerance requirements. The substitute demonstrates superior response time (300ns versus 400ns) and lower supply current consumption (15mA versus 28mA typical).

Product Status and Compliance: The T60404N4647X663 is an active product in current production, ensuring long-term availability and supply chain continuity. Both the original and substitute parts maintain RoHS compliance (RoHS Compliant and ROHS3 Compliant respectively), satisfying environmental regulatory requirements.

Mechanical Considerations: The substitute part utilizes a 10-DIP module package format, differing from the original single pass-through module configuration. PCB layout and mounting hole spacing must be verified for mechanical compatibility in the target application.

Frequently Asked Questions (FAQ)

Q: Can the T60404N4647X663 directly replace the LTS 6-NP/SP2 in existing designs?

A: Electrical substitution is valid across all critical measurement parameters. Mechanical compatibility requires verification of the 10-DIP module footprint against the original single pass-through module layout. PCB redesign may be necessary to accommodate the different package configuration.

Q: What is the significance of the accuracy difference between ±0.2% and ±0.7%?

A: The original LTS 6-NP/SP2 specifies ±0.2% accuracy, while the T60404N4647X663 specifies ±0.7%. This represents a wider tolerance band on the substitute part. Applications requiring measurement accuracy better than ±0.7% must evaluate whether this specification change is acceptable for the intended use case.

Q: Are both parts RoHS compliant?

A: Yes. The LTS 6-NP/SP2 is RoHS Compliant, and the T60404N4647X663 is ROHS3 Compliant. Both meet current environmental regulatory requirements for electronic components.

Q: What are the key electrical parameters that determine substitution compatibility?

A: Substitution compatibility is determined by matching current sensing capacity (6A), closed-loop sensor topology, single-channel configuration, ratiometric voltage output, frequency response (DC to 200kHz), supply voltage range (4.75V to 5.25V), and operating temperature range (-40°C to 85°C).

Q: Does the substitute part consume less power than the original?

A: Yes. The T60404N4647X663 draws a maximum of 15mA supply current compared to 28mA typical for the LTS 6-NP/SP2, representing a 46% reduction in power consumption.

Q: What is the response time difference between these parts?

A: The T60404N4647X663 has a response time of 300ns, which is 100ns faster than the LTS 6-NP/SP2 at 400ns. This faster response may provide improved performance in time-sensitive measurement applications.

Q: Why is the original part classified as obsolete?

A: The LTS 6-NP/SP2 is no longer in active production. The T60404N4647X663 is an active substitute that provides equivalent electrical functionality while ensuring continued availability and supply chain support.

Q: Are there any polarization differences between these sensors?

A: Yes. The LTS 6-NP/SP2 is bidirectional, while the T60404N4647X663 is unidirectional. Applications requiring bidirectional current measurement must confirm that unidirectional operation is acceptable for the intended measurement scenario.
