Engineering Selection Recommendations

All four parts (LXS 15-NPS, LES 15-NP, LPSR 15-NP, LXSR 15-NPS) are active products with identical RoHS compliance and REACH status, confirming regulatory equivalence for current applications.

LES 15-NP exhibits reduced maximum supply current (20.8mA versus 27.5mA) while maintaining identical accuracy (±2.25%). This part is suitable for applications with constrained power supply capacity.

LPSR 15-NP and LXSR 15-NPS both provide improved accuracy specification (±1.25% versus ±2.25%) with identical maximum supply current (27.5mA). These parts are suitable for applications requiring tighter measurement accuracy.

All substitute parts maintain the same through-hole mounting configuration, module package type, and thermal operating range, ensuring mechanical and thermal compatibility with existing PCB designs and thermal management strategies.

Frequently Asked Questions (FAQ)

Q: Can LES 15-NP replace LXS 15-NPS in all applications?

A: LES 15-NP maintains all critical electrical parameters including current range, sensitivity, frequency response, and accuracy. The primary difference is reduced maximum supply current (20.8mA versus 27.5mA). Substitution is valid when the application power budget accommodates the lower supply current specification.

Q: What is the difference between LPSR 15-NP and LXSR 15-NPS?

A: Both parts are electrically identical with ±1.25% accuracy and 27.5mA maximum supply current. The difference is series designation (LPSR versus LXSR). Both are direct substitutes for LXS 15-NPS when improved accuracy is required.

Q: Are all substitute parts through-hole mounted?

A: Yes. LXS 15-NPS, LES 15-NP, LPSR 15-NP, and LXSR 15-NPS all use through-hole mounting in module package configuration, ensuring identical PCB integration requirements.

Q: Does accuracy difference affect circuit design?

A: The LXS 15-NPS and LES 15-NP specify ±2.25% accuracy, while LPSR 15-NP and LXSR 15-NPS specify ±1.25% accuracy. Circuit designs must account for the applicable accuracy specification of the selected part. Tighter accuracy requirements necessitate selection of LPSR 15-NP or LXSR 15-NPS.

Q: Are all parts RoHS compliant?

A: Yes. LXS 15-NPS, LES 15-NP, LPSR 15-NP, and LXSR 15-NPS are all RoHS compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the supply voltage requirement for all substitute parts?

A: All four parts require identical supply voltage range of 4.75V to 5.25V. Power supply design must accommodate this specification for all substitute parts.
