LTS 6-NP/SP3 Current Transducer Equivalent & Substitute Parts

Part Overview

The LTS 6-NP/SP3 is a 6A current transducer manufactured by LEM USA Inc., designed for AC/DC current measurement applications. This Hall Effect, closed-loop bidirectional sensor operates across a frequency range of DC to 200kHz with a single pass-through channel configuration. The product is classified as obsolete, necessitating identification of active equivalent components to maintain system functionality and ensure continued availability for new designs and field replacements.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the LTS 6-NP/SP3 is based on alignment of the following critical parameters:

Mandatory Matching Parameters:

• Current sensing capacity: 6A
• Sensor technology: Closed loop configuration
• Number of channels: 1
• Output format: Ratiometric voltage output
• Frequency range: DC ~ 200kHz minimum
• Supply voltage range: 4.75V ~ 5.25V
• Operating temperature range: -40°C ~ 85°C
• Mounting configuration: Through hole

Acceptable Variation Parameters:

• Polarization: Unidirectional substitutes are acceptable for applications not requiring bidirectional measurement
• Response time: Faster response times are acceptable
• Accuracy: Tolerance degradation within engineering specifications
• Current supply: Lower maximum supply current is acceptable
• Package form factor: Module configurations with equivalent electrical performance

The T60404N4647X663 from VACUUMSCHMELZE meets these substitution criteria as an active product with compatible electrical specifications and through-hole mounting.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: T60404N4647X663

The T60404N4647X663 is the designated substitute for the obsolete LTS 6-NP/SP3. This component is currently in active production status, ensuring long-term availability and supply chain continuity.

Compliance Considerations:

Both the main part and substitute meet RoHS compliance requirements. The LTS 6-NP/SP3 carries RoHS Compliant status, while the T60404N4647X663 meets ROHS3 Compliant standards, representing an equivalent or enhanced environmental compliance posture.

Electrical Performance:

The substitute maintains critical electrical specifications including 6A current sensing capacity, DC to 200kHz frequency range, and 4.75V to 5.25V supply voltage compatibility. Both components deliver ratiometric voltage output with ±0.1% linearity. The T60404N4647X663 exhibits improved response time (300ns versus 400ns) and reduced supply current draw (15mA versus 28mA typical).

Accuracy Trade-off:

The substitute exhibits reduced accuracy specification (±0.7% versus ±0.2%). Applications requiring the original ±0.2% accuracy specification must evaluate whether the ±0.7% tolerance of the substitute meets system-level requirements.

Polarization Difference:

The LTS 6-NP/SP3 provides bidirectional measurement capability, while the T60404N4647X663 operates as a unidirectional sensor. Applications requiring bidirectional current measurement must confirm that unidirectional operation is acceptable for the intended application.

Package Consideration:

The substitute employs a 10-DIP module package configuration, differing from the single pass-through module form of the original part. PCB layout and mechanical mounting must be evaluated for compatibility with the new package footprint.

Frequently Asked Questions (FAQ)

Q: Can the T60404N4647X663 directly replace the LTS 6-NP/SP3 without circuit modifications?

A: The T60404N4647X663 maintains electrical compatibility in terms of current sensing range, supply voltage, frequency response, and output format. However, the different package configuration (10-DIP versus single pass-through module) requires PCB layout evaluation. Additionally, the unidirectional polarization of the substitute must be confirmed as acceptable for applications originally designed for bidirectional measurement.

Q: What is the impact of the accuracy difference between these components?

A: The LTS 6-NP/SP3 specifies ±0.2% accuracy, while the T60404N4647X663 specifies ±0.7% accuracy. This represents a 0.5% absolute difference. Applications with tight accuracy requirements must verify that the substitute's ±0.7% specification remains within system-level tolerance budgets.

Q: Are there any supply chain advantages to using the substitute?

A: Yes. The T60404N4647X663 is classified as an active product with 2938 pieces in stock, compared to the obsolete status of the LTS 6-NP/SP3. This ensures continued availability for production and field replacement applications.

Q: Does the faster response time of the substitute present any compatibility concerns?

A: No. The T60404N4647X663 response time of 300ns is faster than the original 400ns specification. Faster response times do not introduce compatibility issues and may provide performance benefits in high-speed measurement applications.

Q: What is the significance of the reduced supply current in the substitute?

A: The T60404N4647X663 draws a maximum of 15mA compared to the LTS 6-NP/SP3 typical draw of 28mA. This reduction decreases power consumption and thermal load on the supply circuit, providing a secondary benefit in power-constrained applications.

Q: How does the unidirectional polarization of the substitute affect application compatibility?

A: The LTS 6-NP/SP3 measures current in both directions (bidirectional), while the T60404N4647X663 measures current in one direction only (unidirectional). Applications that require measurement of current reversal or bidirectional flow must confirm that unidirectional operation is acceptable, or identify alternative substitutes with bidirectional capability.

Q: Are both components RoHS compliant?

A: Yes. The LTS 6-NP/SP3 is RoHS Compliant, and the T60404N4647X663 is ROHS3 Compliant. Both meet environmental compliance requirements for restricted substance use.
