Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HS250 16R F are identified based on the following critical parameters that determine functional equivalence:

• Resistance value: 16 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Composition: Wirewound (exact match required)
• Housing type: Aluminum (exact match required)
• Mounting feature: Flanges with M6 threaded leads (exact match required)
• RoHS compliance: Required for regulatory equivalence

The HS200 16R F from ARCOL meets these core substitution criteria. The primary difference is the power rating reduction from 250W to 200W. This substitute is applicable in applications where the thermal load does not exceed 200 watts continuous operation.

Parameter Comparison

Engineering Selection Recommendations

Selection between the HS250 16R F and HS200 16R F is determined by application power requirements. Both parts maintain active product status and full RoHS compliance. The HS250 16R F is specified for applications requiring 250-watt continuous power dissipation capability. The HS200 16R F substitute is suitable for applications with maximum continuous power dissipation of 200 watts. Electrical characteristics including resistance value, tolerance, and temperature coefficient remain functionally equivalent. Physical mounting dimensions and lead configuration are identical, ensuring direct mechanical compatibility in flanged chassis mount installations.

Frequently Asked Questions (FAQ)

Q: Can the HS200 16R F replace the HS250 16R F in all applications?

A: The HS200 16R F is a substitute only for applications where continuous power dissipation does not exceed 200 watts. Applications requiring the full 250-watt capability must use the HS250 16R F.

Q: Are the physical dimensions identical between these parts?

A: The height and width dimensions are identical. The HS250 16R F has a length of 4.319" (109.70mm), while the HS200 16R F has a length of 4.631" (89.70mm). Both maintain the same 1.646" (41.80mm) seated height and identical flange mounting configuration.

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

A: The HS250 16R F specifies 100ppm/°C, while the HS200 16R F specifies ±100ppm/°C. Both values fall within acceptable tolerance ranges for wirewound resistor applications.

Q: Are both parts RoHS compliant?

A: Yes, both the HS250 16R F and HS200 16R F are RoHS compliant with MSL rating of 1 (Unlimited).

Q: What is the packaging difference between these parts?

A: The HS250 16R F is supplied in box packaging, while the HS200 16R F is supplied in bulk packaging. This affects inventory management and handling but does not impact electrical or mechanical performance.
