Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HO 8-NSM-0000 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Current sensing range: 8A
• Sensor technology: Hall Effect, Open Loop
• Number of channels: 1
• Output configuration: Ratiometric, Voltage
• Measurement capability: AC/DC
• Frequency response: DC ~ 250kHz
• Linearity tolerance: ±0.5%
• Accuracy specification: ±1%
• Response time: 3.5µs
• Maximum supply current: 25mA
• Operating temperature range: -40°C ~ 105°C
• Polarization: Bidirectional
• Mounting type: Surface Mount
• Package type: Module
• Regulatory compliance: RoHS Compliant, REACH Unaffected

Variable Parameter Allowing Substitution:

• Voltage supply requirement: 5V (main part) vs. 3.3V (substitute part)

The HO 8-NSM/SP33-1000 qualifies as a parametric equivalent because it maintains all mandatory electrical and mechanical specifications while accommodating a different supply voltage of 3.3V. This variation is permissible when the application circuit supports 3.3V logic levels and power delivery.

Parameter Comparison

Engineering Selection Recommendations

HO 8-NSM-0000 Selection Criteria:

• Primary choice when 5V supply voltage is available in the application circuit
• Preferred for systems with established 5V power distribution infrastructure
• Active product status with 1207 units in current inventory
• Full RoHS compliance and REACH unaffected status confirmed

HO 8-NSM/SP33-1000 Selection Criteria:

• Applicable when application circuit operates on 3.3V logic and power supply
• Suitable for low-power or battery-operated systems requiring 3.3V compatibility
• Active product status with 725 units in current inventory
• Maintains identical RoHS compliance and REACH unaffected status
• Electrical and mechanical performance parameters remain equivalent to primary part

Both parts maintain active production status, full regulatory compliance, and identical core sensor performance specifications. Selection between these parts depends solely on the voltage supply architecture of the target application circuit.

Frequently Asked Questions (FAQ)

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

A: The HO 8-NSM/SP33-1000 is a parametric equivalent only when the application circuit supports 3.3V supply voltage. All electrical performance parameters, including current sensing range, accuracy, linearity, frequency response, and response time, are identical. The only difference is the supply voltage requirement. Direct substitution is valid only if the circuit design accommodates 3.3V operation.

Q: What are the critical parameters that must match for substitution?

A: The following parameters must remain identical for valid substitution: 8A current sensing range, Hall Effect open-loop sensor type, single-channel configuration, ratiometric voltage output, AC/DC measurement capability, DC to 250kHz frequency response, ±0.5% linearity, ±1% accuracy, 3.5µs response time, 25mA maximum supply current, -40°C to 105°C operating temperature, bidirectional polarization, surface mount configuration, and module package type.

Q: Are there any other substitute parts available for the HO 8-NSM-0000?

A: Based on the provided data, HO 8-NSM/SP33-1000 is the only identified parametric equivalent. This part maintains all mandatory electrical and mechanical specifications while accommodating a different supply voltage.

Q: What is the inventory status for both parts?

A: HO 8-NSM-0000 has 1207 units in stock. HO 8-NSM/SP33-1000 has 725 units in stock. Both are listed as active products.

Q: Do both parts have the same regulatory compliance?

A: Yes. Both HO 8-NSM-0000 and HO 8-NSM/SP33-1000 are RoHS Compliant and REACH Unaffected. They share identical ECCN (EAR99) and HTSUS (9030.33.3800) classifications.

Q: What is the primary difference between these two parts?

A: The sole difference is the supply voltage specification. HO 8-NSM-0000 requires 5V supply, while HO 8-NSM/SP33-1000 requires 3.3V supply. All other electrical performance characteristics and mechanical specifications are identical.

Q: Can I use HO 8-NSM-0000 in a 3.3V system?

A: No. The HO 8-NSM-0000 is specified for 5V supply voltage operation. Using it in a 3.3V system would operate the device outside its specified parameters. Use HO 8-NSM/SP33-1000 for 3.3V applications.
