HS150 510R J Equivalent & Substitute Parts

Part Overview

The HS150 510R J is a 150-watt wirewound chassis mount resistor manufactured by Ohmite, rated at 510 ohms with ±5% tolerance. This component is designed for high-power applications requiring pulse withstanding capability and thermal stability. The part maintains Active product status with full RoHS compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts become necessary when application constraints such as space limitations, thermal management requirements, or inventory availability necessitate alternative configurations while maintaining core electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

The HS75 510R J qualifies as a parametric equivalent based on the following criteria:

Matching Parameters:

• Resistance value: 510 Ohms (identical)
• Tolerance: ±5% (identical)
• Composition: Wirewound (identical)
• Temperature Coefficient: ±100ppm/°C (equivalent performance)
• Housing Type: Aluminum (identical)
• Mounting Feature: Flanges (identical)
• Lead Style: Solder Lugs (identical)
• RoHS Compliance: Yes (identical)
• MSL Rating: 1 (Unlimited) (identical)

Differing Parameter:

• Power Rating: 75W (versus 150W in main part)

The HS75 510R J operates at half the power rating of the HS150 510R J. This substitute is applicable only in applications where the thermal load does not exceed 75 watts continuous dissipation. The reduced physical dimensions (1.917" L x 1.075" W versus 3.846" L x 1.870" W) reflect the lower power capability.

Parameter Comparison

Engineering Selection Recommendations

Both the HS150 510R J and HS75 510R J maintain Active product status with full RoHS compliance and identical moisture sensitivity ratings. Selection between these components is determined by application power dissipation requirements. The HS150 510R J is specified for applications requiring continuous power dissipation up to 150 watts. The HS75 510R J is suitable for applications with power dissipation not exceeding 75 watts. The reduced physical footprint of the HS75 510R J may provide advantages in space-constrained designs operating within its power specification. Both components feature identical electrical characteristics (resistance, tolerance, temperature coefficient) and mounting interfaces, ensuring functional compatibility within their respective power ratings.

Frequently Asked Questions (FAQ)

Q: Can the HS75 510R J replace the HS150 510R J in all applications?

A: No. The HS75 510R J is suitable only for applications where continuous power dissipation does not exceed 75 watts. Applications requiring the full 150-watt capability must use the HS150 510R J or equivalent 150-watt rated component.

Q: Are the electrical characteristics identical between these parts?

A: Yes. Both components provide 510 ohms ±5% resistance with 100ppm/°C temperature coefficient performance. The primary difference is power rating and resulting physical dimensions.

Q: Do both parts use the same mounting interface?

A: Yes. Both components feature aluminum housing with flanged mounting and solder lug leads, enabling direct mechanical substitution in applications within the HS75 510R J power specification.

Q: What is the height difference between these components?

A: Both components have identical seated height of 0.949" (24.10mm). The HS75 510R J is smaller in length and width due to its lower power rating.

Q: Are both parts RoHS compliant?

A: Yes. Both the HS150 510R J and HS75 510R J are RoHS compliant with MSL 1 (Unlimited) moisture sensitivity rating.
