Substitute Part Grouping Explanation

Substitution between HO 6-P and HO 6-P/SP33 is based on electrical and mechanical parameter equivalence within the HO-P series family. Both parts maintain identical specifications for current sensing range (6A), sensor type (Hall Effect, Open Loop), channel count (1), output type (Ratiometric Voltage), frequency response (DC ~ 250kHz), linearity (±0.5%), accuracy (±1.4%), response time (3.5µs), operating temperature range (-40°C ~ 105°C), polarization (Bidirectional), mounting type (Through Hole), and package configuration (Module, Single Pass Through).

The primary differentiator is the supply voltage specification: HO 6-P operates at 5V supply, while HO 6-P/SP33 operates at 3.3V supply. This distinction determines circuit compatibility and power delivery requirements. Both variants maintain maximum supply current of 25mA and are RoHS Compliant with REACH Unaffected status. Selection between these variants depends exclusively on the host system's available supply voltage and downstream signal processing requirements.

Parameter Comparison

Engineering Selection Recommendations

Both HO 6-P and HO 6-P/SP33 are Active products with full regulatory compliance. Selection between these variants is determined by system power supply architecture:

HO 6-P (5V Supply): Select this variant for systems with 5V power rails or where 5V supply voltage is the primary available source. This configuration is suitable for standard industrial control systems and legacy designs utilizing 5V logic levels.

HO 6-P/SP33 (3.3V Supply): Select this variant for modern embedded systems, microcontroller-based designs, and applications where 3.3V supply voltage is the primary available source. This configuration is compatible with contemporary digital signal processors and low-power system architectures.

Both variants maintain identical measurement performance specifications, environmental ratings, and compliance certifications. The choice between them is purely a function of available supply voltage in the target application circuit. No performance trade-offs exist between the two variants within their respective supply voltage domains.

Frequently Asked Questions (FAQ)

Q: Can HO 6-P and HO 6-P/SP33 be used interchangeably in the same circuit?

A: No. These variants require different supply voltages (5V versus 3.3V). Direct substitution without circuit modification will result in improper sensor operation. The host system must provide the correct supply voltage for the selected variant.

Q: Are the output signal levels different between HO 6-P and HO 6-P/SP33?

A: Both variants provide ratiometric voltage output. The output signal scales proportionally to the supply voltage. HO 6-P outputs are referenced to 5V, while HO 6-P/SP33 outputs are referenced to 3.3V. Downstream signal conditioning circuits must be designed accordingly.

Q: Do both variants have identical measurement accuracy?

A: Yes. Both HO 6-P and HO 6-P/SP33 maintain ±1.4% accuracy and ±0.5% linearity specifications. Measurement performance is equivalent across both variants.

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

A: Both variants use identical Through Hole mounting and Module, Single Pass Through package configuration. Physical form factor and PCB footprint are identical. The difference is internal to the sensor electronics.

Q: Are both variants RoHS compliant?

A: Yes. Both HO 6-P and HO 6-P/SP33 are RoHS Compliant and REACH Unaffected. Both meet current environmental and regulatory requirements.

Q: Can I use HO 6-P/SP33 in a 5V system?

A: No. HO 6-P/SP33 is specified for 3.3V supply voltage. Operating this variant at 5V will exceed design specifications and may cause component damage or failure.

Q: What is the current consumption difference between variants?

A: Both variants have identical maximum supply current specification of 25mA. Current consumption is equivalent.

Q: Are there any temperature rating differences?

A: No. Both variants operate across the identical temperature range of -40°C to 105°C.
