Key Parameters

Substitute Part Grouping Explanation

Substitution for the HS250 150R F is determined by the following critical parameters:

• Resistance Value: Must be 150 Ohms
• Tolerance: Must be ±1%
• Composition: Must be Wirewound
• Housing Type: Must be Aluminum
• Mounting Feature: Must include Flanges
• Lead Style: Must be M6 Threaded
• RoHS Compliance: Must be RoHS Compliant

The HS200 150R F qualifies as a parametric equivalent under these criteria. While the power rating differs (200W versus 250W), all core electrical and mechanical parameters align with the substitution requirements for this resistor category. Power rating variance is acceptable when the substitute part meets or exceeds the minimum power requirement of the application circuit.

Parameter Comparison

Engineering Selection Recommendations

Both the HS250 150R F and HS200 150R F maintain Active product status with full RoHS compliance and ECCN EAR99 classification. Selection between these parts depends on application power dissipation requirements. The HS250 150R F provides 250W capacity, while the HS200 150R F provides 200W capacity. For applications requiring the full 250W rating, the primary part is specified. For applications with power dissipation at or below 200W, the HS200 150R F serves as a direct substitute with identical electrical performance and mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can the HS200 150R F replace the HS250 150R F in all applications?

A: The HS200 150R F is suitable for applications where power dissipation does not exceed 200W. If your circuit requires the full 250W capacity, the HS250 150R F must be used. Verify your application's actual power dissipation before substitution.

Q: Are the physical dimensions compatible between these parts?

A: Both parts feature M6 threaded leads and flange mounting. The HS250 150R F measures 4.319" L x 2.854" W with 1.646" seated height. The HS200 150R F measures 4.631" L x 1.791" W with 1.646" seated height. Verify mounting space availability in your design before substitution.

Q: Do these parts have identical electrical specifications?

A: Both parts provide 150 Ohms ±1% resistance with wirewound composition and aluminum housing. Temperature coefficient specifications are 100ppm/°C (HS250 150R F) and ±100ppm/°C (HS200 150R F), both acceptable for standard applications. RoHS compliance and MSL ratings are identical.

Q: What is the difference in packaging between these parts?

A: The HS250 150R F is supplied in Box packaging, while the HS200 150R F is supplied in Bulk packaging. Confirm packaging requirements for your procurement and assembly processes.

Q: Are both parts currently available?

A: Both parts maintain Active product status. The HS250 150R F has 1065 pieces in stock, and the HS200 150R F has 721 pieces in stock. Verify current availability with your supplier for your required delivery timeline.
