Engineering Selection Recommendations

HO 8-NP-0000 (5V Supply Variant)

Select this part number for systems operating on 5V supply rails. Both the HO 8-NP-0000 and HO 8-NP/SP33-1000 are Active status products from LEM USA Inc. with identical RoHS Compliant and REACH Unaffected certifications. The 5V supply specification makes this variant suitable for standard industrial control systems and legacy 5V logic environments.

HO 8-NP/SP33-1000 (3.3V Supply Variant)

Select this part number for systems operating on 3.3V supply rails, including modern microcontroller platforms and low-power embedded systems. This variant maintains all electrical performance specifications of the 5V model while accommodating reduced supply voltage requirements.

Selection Basis:

Both parts share identical sensing performance, accuracy, linearity, frequency response, and temperature operating range. The substitution decision is determined solely by system supply voltage compatibility. Both parts carry equivalent compliance certifications (RoHS Compliant, REACH Unaffected, ECCN EAR99) and are manufactured by the same supplier within the same product series.

Frequently Asked Questions (FAQ)

Q: Can HO 8-NP/SP33-1000 be used as a direct replacement for HO 8-NP-0000?

A: Direct replacement is possible only if the system supply voltage is 3.3V. The HO 8-NP/SP33-1000 is designed for 3.3V operation, while the HO 8-NP-0000 requires 5V supply. Operating either part outside its specified supply voltage range will result in incorrect output scaling and measurement error.

Q: Are the sensing characteristics identical between these two part numbers?

A: Yes. Both parts provide identical current sensing range (8A), accuracy (±1%), linearity (±0.5%), frequency response (DC ~ 250kHz), response time (3.5µs), and operating temperature range (-40°C ~ 105°C). The only difference is the supply voltage specification.

Q: What is the significance of the "/SP33" designation in HO 8-NP/SP33-1000?

A: The "/SP33" suffix indicates the 3.3V supply voltage variant within the HO-NP-0000 series. This is a manufacturer designation for supply voltage differentiation.

Q: Are both parts through-hole mounted?

A: Yes. Both HO 8-NP-0000 and HO 8-NP/SP33-1000 use through-hole mounting and are packaged as modules with identical mechanical form factors.

Q: Do both parts have the same RoHS and REACH compliance status?

A: Yes. Both parts are RoHS Compliant and REACH Unaffected, with identical ECCN (EAR99) and HTSUS (9030.33.3800) classifications.

Q: What is the maximum current supply requirement for both parts?

A: Both parts have a maximum current supply of 25mA.

Q: Can these parts measure both AC and DC current?

A: Yes. Both HO 8-NP-0000 and HO 8-NP/SP33-1000 are specified for AC/DC current measurement with bidirectional polarization capability.
