Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the HSA5075RJ are identified based on the following critical parameters that must align for direct substitution:

Primary Electrical Parameters:

• Resistance value: 75 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)

Compliance Parameters:

• RoHS3 Compliant status (required for regulatory equivalence)

The substitute part TMC05075R00FE02 satisfies all primary electrical, mechanical, and compliance requirements. Variations in tolerance, temperature coefficient, and maximum operating temperature represent enhanced performance characteristics that do not prevent substitution but indicate improved specifications in specific application scenarios.

Parameter Comparison

Engineering Selection Recommendations

Both the HSA5075RJ and TMC05075R00FE02 maintain Active product status, ensuring continued availability and manufacturer support. Both components are ROHS3 Compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and distribution.

The TMC05075R00FE02 substitute provides enhanced tolerance specification (±1% versus ±5%) and improved temperature coefficient performance (±20ppm/°C versus ±50ppm/°C), resulting in superior resistance stability across temperature variations. The extended maximum operating temperature of 250°C compared to 200°C provides additional thermal margin in high-temperature applications. The moisture-resistant feature of the substitute part offers enhanced environmental protection.

Selection between the main part and substitute should be based on application-specific requirements for tolerance precision, temperature stability, and thermal operating envelope. Both components satisfy identical mechanical mounting requirements and electrical power dissipation specifications.

Frequently Asked Questions (FAQ)

Q: Can TMC05075R00FE02 directly replace HSA5075RJ in existing circuit designs?

A: Yes. Both components share identical resistance value (75 Ohms), power rating (50W), composition (wirewound), mounting configuration (flanged solder lugs), and housing material (aluminum). Mechanical and electrical compatibility is confirmed.

Q: What is the significance of the tolerance difference between ±5% and ±1%?

A: Tolerance specification defines the acceptable resistance variation from the nominal 75 Ohm value. The HSA5075RJ permits variation between 71.25 and 78.75 Ohms. The TMC05075R00FE02 restricts variation to 74.25 and 75.75 Ohms. Applications requiring tighter resistance control benefit from the ±1% specification.

Q: Does the temperature coefficient difference affect substitution compatibility?

A: Temperature coefficient (±50ppm/°C versus ±20ppm/°C) describes resistance change per degree Celsius. The substitute part exhibits lower resistance drift across temperature variations, providing improved stability. This represents enhanced performance and does not prevent substitution.

Q: Are both parts suitable for the full -55°C to 200°C operating range?

A: The HSA5075RJ operates across -55°C to 200°C. The TMC05075R00FE02 extends this range to -55°C to 250°C. Both components function within the HSA5075RJ specification range. Applications exceeding 200°C benefit from the substitute part's extended thermal capability.

Q: What does "moisture resistant" feature indicate for the substitute part?

A: Moisture resistance describes enhanced protection against environmental moisture ingress. This feature improves long-term reliability in humid or corrosive environments without affecting electrical or mechanical compatibility.

Q: Are packaging and lead configurations identical?

A: Yes. Both components utilize solder lug lead style, flanged mounting configuration, and axial box packaging. Physical mounting and electrical connection methods are identical.

Q: Do both parts meet current compliance requirements?

A: Yes. Both HSA5075RJ and TMC05075R00FE02 are ROHS3 Compliant and maintain Active product status, confirming current regulatory compliance and manufacturer support.
