THS5015RJ Equivalent & Substitute Parts

Part Overview

The THS5015RJ is a 15 Ohms ±5% 50W wirewound chassis mount resistor manufactured by TE Connectivity Passive Product. This component is classified as Active product status and is designed for applications requiring high power dissipation with flanged mounting configuration. The resistor features aluminum housing with solder lug terminations and operates across a temperature range of -55°C to 200°C. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when enhanced specifications are required for specific application demands.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the THS5015RJ are qualified based on the following critical parameters that determine functional equivalence:

Core Electrical Parameters:

• Resistance value: 15 Ohms (exact match required)
• Power rating: 50W (exact match required)
• Composition: Wirewound (exact match required)

Mechanical Parameters:

• Mounting feature: Flanges (exact match required)
• Lead style: Solder Lugs (exact match required)
• Housing type: Aluminum (exact match required)
• Package configuration: Axial, Box (exact match required)

Compliance Parameters:

• RoHS3 Compliant status (required)
• REACH Unaffected status (required)
• ECCN EAR99 classification (required)

The substitute parts identified (KAL50FB15R0 and UAL50-15RF8) meet all core electrical, mechanical, and compliance requirements. These substitutes offer enhanced tolerance specifications (±1% versus ±5%) and extended operating temperature ranges, providing upgraded performance characteristics while maintaining full compatibility with the original part's mounting and electrical interface requirements.

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts (KAL50FB15R0 and UAL50-15RF8) are qualified as direct equivalents to the THS5015RJ based on matching core electrical specifications, mechanical mounting requirements, and regulatory compliance status. All three parts maintain ROHS3 compliance, REACH Unaffected status, and EAR99 ECCN classification.

The KAL50FB15R0 from Stackpole Electronics Inc provides improved tolerance specification (±1% versus ±5%) and extended operating temperature capability to 275°C, with moisture-resistant features and reduced temperature coefficient (±30ppm/°C).

The UAL50-15RF8 from Riedon offers the most stringent tolerance specification (±1%) and lowest temperature coefficient (±20ppm/°C), with extended operating temperature range to 275°C. This part includes additional functional features including current sense capability, flame proof construction, pulse withstanding rating, and safety certifications. The MSL rating of 1 (Unlimited) indicates no moisture sensitivity constraints.

Selection between these substitutes depends on application-specific requirements for tolerance precision, temperature stability, and operational temperature limits. All three parts are Active status products with current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can KAL50FB15R0 or UAL50-15RF8 be used as direct replacements for THS5015RJ in existing designs?

A: Yes. Both substitute parts match the core electrical specifications (15 Ohms, 50W, wirewound composition), mechanical mounting configuration (flanged aluminum housing with solder lugs), and regulatory compliance requirements (ROHS3, REACH Unaffected, EAR99). The physical dimensions are comparable across all three parts, with maximum seated heights ranging from 16.00mm to 17.00mm.

Q: What are the key differences between the substitute parts?

A: The primary differences are tolerance specification, temperature coefficient, and maximum operating temperature. KAL50FB15R0 provides ±1% tolerance with ±30ppm/°C temperature coefficient and 275°C maximum operating temperature. UAL50-15RF8 provides ±1% tolerance with ±20ppm/°C temperature coefficient and 275°C maximum operating temperature, plus additional features including current sense, flame proof, and pulse withstanding capabilities.

Q: Are there packaging differences between THS5015RJ and the substitute parts?

A: THS5015RJ is supplied in Tray packaging, while KAL50FB15R0 and UAL50-15RF8 are supplied in Bulk packaging. The component package configuration (Axial, Box) remains identical across all three parts.

Q: What is the temperature coefficient significance for these resistors?

A: Temperature coefficient indicates resistance value change per degree Celsius. THS5015RJ has ±50ppm/°C, while both substitutes have lower coefficients (±30ppm/°C for KAL50FB15R0 and ±20ppm/°C for UAL50-15RF8). Lower temperature coefficients provide greater resistance stability across temperature variations.

Q: Do all three parts meet the same regulatory requirements?

A: Yes. THS5015RJ, KAL50FB15R0, and UAL50-15RF8 are all ROHS3 Compliant, REACH Unaffected, and classified as EAR99 for export control purposes.

Q: What does the ±1% tolerance specification mean compared to ±5%?

A: Tolerance indicates the allowable deviation from the nominal 15 Ohm resistance value. ±5% tolerance (THS5015RJ) allows resistance values between 14.25 and 15.75 Ohms. ±1% tolerance (both substitutes) allows resistance values between 14.85 and 15.15 Ohms, providing tighter resistance control for precision applications.
