Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: LESR 15-NP

The LESR 15-NP is the manufacturer-recommended substitute for the LESR 15-NP KIT. This part maintains identical electrical and mechanical specifications while offering the advantage of active product status. The LESR 15-NP is supplied in tray packaging and represents the current production equivalent. Selection of this part ensures ongoing manufacturer support and supply chain continuity.

Secondary Equivalent: LXSR 15-NPS KIT

The LXSR 15-NPS KIT provides parametric equivalence with all critical electrical and mechanical specifications matching the original LESR 15-NP KIT. This part is supplied in bulk packaging as a 3-piece kit. Although classified as obsolete, it maintains full functional compatibility. This option is suitable for applications where kit configuration and bulk packaging are preferred.

Compliance Considerations

All substitute parts maintain RoHS compliance and REACH unaffected status, ensuring regulatory alignment with the original component. No additional compliance verification is required for direct substitution.

Frequently Asked Questions (FAQ)

Q: Can LESR 15-NP be used as a direct replacement for LESR 15-NP KIT?

A: Yes. The LESR 15-NP provides identical electrical performance and mechanical compatibility. The primary difference is packaging: LESR 15-NP is supplied individually in tray packaging, while LESR 15-NP KIT is a 3-piece kit. For single-unit applications, LESR 15-NP is the appropriate selection.

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

A: Both parts are 3-piece kits with identical electrical specifications and performance characteristics. The primary difference is the series designation (LESR versus LXSR) and packaging format (kit versus bulk). Both are classified as obsolete products.

Q: Are there any performance differences between the substitute parts?

A: No. All substitute parts maintain identical specifications for current sensing range, sensitivity, frequency response, linearity, accuracy, supply voltage, response time, operating temperature range, and polarization. Electrical and mechanical performance is equivalent across all listed substitutes.

Q: What packaging options are available?

A: LESR 15-NP is supplied in tray packaging as individual units. LESR 15-NP KIT and LXSR 15-NPS KIT are both supplied as 3-piece kits, with LESR 15-NP KIT in kit packaging and LXSR 15-NPS KIT in bulk packaging.

Q: Is LESR 15-NP still in active production?

A: Yes. LESR 15-NP is classified as an active product, making it the recommended choice for new designs and ongoing procurement. LESR 15-NP KIT and LXSR 15-NPS KIT are both obsolete.

Q: Do all substitutes meet the same regulatory requirements?

A: Yes. All substitute parts are RoHS compliant and REACH unaffected, matching the regulatory status of the original LESR 15-NP KIT.

Q: Can these parts be used interchangeably in existing designs?

A: Yes, provided the application accommodates the packaging format. LESR 15-NP (individual tray packaging) and the kit versions (LESR 15-NP KIT, LXSR 15-NPS KIT) are electrically and mechanically interchangeable. Verify that your application design supports the selected packaging configuration.
