Substitute Part Grouping Explanation

Substitute parts for the LPSR 25-NP are identified based on strict parametric equivalence across all electrical and mechanical specifications. The substitution logic is based on the following criteria:

Substitution Criteria:

  • Current sensing capacity: 25A
  • Sensor technology: Hall Effect, Closed Loop
  • Output configuration: Ratiometric, Voltage
  • Sensitivity: 25mV/A
  • Frequency response: 300kHz
  • Linearity tolerance: ±0.1%
  • Accuracy: ±1.25%
  • Supply voltage range: 4.75V ~ 5.25V
  • Response time: 400ns
  • Maximum supply current: 32.5mA
  • Operating temperature range: -40°C ~ 105°C
  • Polarization: Bidirectional
  • Mounting: Through Hole
  • Package: Module
  • Compliance: RoHS Compliant, REACH Unaffected

The substitute parts LESR 25-NP and LKSR 25-NP are members of different LEM series but maintain identical electrical performance and mechanical compatibility with the LPSR 25-NP. All three parts share the same parametric specifications, enabling direct functional substitution in circuit designs.

Frequently Asked Questions (FAQ)

Q: Can LESR 25-NP and LKSR 25-NP be used as direct replacements for LPSR 25-NP?

A: Yes. All three parts share identical electrical specifications including current sensing capacity (25A), output type (ratiometric voltage), sensitivity (25mV/A), frequency response (300kHz), accuracy (±1.25%), linearity (±0.1%), supply voltage range (4.75V ~ 5.25V), response time (400ns), and operating temperature range (-40°C ~ 105°C). They are mechanically compatible through-hole modules with identical package types. Direct substitution is supported for applications where these parameters are specified.

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

A: Substitution compatibility is determined by: current sensing range (25A), sensor technology (Hall Effect, Closed Loop), output configuration (ratiometric voltage), sensitivity (25mV/A), frequency response (300kHz), linearity (±0.1%), accuracy (±1.25%), supply voltage (4.75V ~ 5.25V), response time (400ns), and bidirectional polarization support. All substitute parts maintain these specifications.

Q: Are there any differences in packaging or mounting between these parts?

A: No. All three parts use identical through-hole mounting, module package type, and tray packaging format. There are no mechanical or packaging differences that would affect circuit board integration or assembly procedures.
