Key Parameters

Substitute Part Grouping Explanation

The 850F750E qualifies as a direct substitute for the HS50 750R F based on the following critical parameters:

Electrical specifications match exactly: 750 ohms resistance, ±1% tolerance, and 50-watt power rating. Both components use wirewound construction with aluminum housing and flanged mounting features. Lead configuration is identical (solder lugs). Package classification is consistent (axial, box format).

Mechanical compatibility is confirmed through equivalent mounting interfaces and similar physical dimensions within acceptable tolerance ranges. Both parts are manufactured by Ohmite and maintain active production status.

Compliance certifications are equivalent or superior: the HS50 750R F carries RoHS Compliant status, while the 850F750E carries ROHS3 Compliant status, representing enhanced environmental compliance. Both are classified under ECCN EAR99 and HTSUS 8533.29.0000.

Parameter Comparison

Engineering Selection Recommendations

Both the HS50 750R F and 850F750E are active production components from Ohmite with full RoHS compliance certifications. The 850F750E carries enhanced ROHS3 compliance status and demonstrates superior temperature coefficient stability (±20ppm/°C versus 100ppm/°C), making it suitable for applications with stricter thermal performance requirements. Selection between these parts should be based on specific application thermal stability needs and packaging requirements (box versus bulk).

Frequently Asked Questions (FAQ)

Q: Can the 850F750E replace the HS50 750R F in existing designs?

A: Yes. Both components share identical electrical specifications (750 ohms, ±1% tolerance, 50W rating), wirewound construction, aluminum housing, flanged mounting, and solder lug leads. Mechanical dimensions are equivalent within standard tolerances.

Q: What is the difference in temperature coefficient between these parts?
