Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RL73H2HR82FTDF is determined by strict equivalence across the following critical parameters:

Resistance value must equal 820 mOhms with ±1% tolerance. Power rating must be 0.75W (3/4W) minimum. Package format must be 2010 (5025 Metric) to ensure mechanical and electrical compatibility with printed circuit board layouts. Composition must be thick film. The component must support current sensing applications. Temperature coefficient must be ±100ppm/°C. Operating temperature range must span -55°C to 155°C. Termination count must be 2. Moisture sensitivity level must be 1 (Unlimited).

The identified substitute part RL73H2HR82FTE meets all electrical and mechanical parameters required for direct substitution. This part shares the same base product number (RL73H2) and series designation (RL73, CGS) as the primary part, confirming functional equivalence.

Parameter Comparison

Engineering Selection Recommendations

The RL73H2HR82FTDF is the primary specification for applications requiring RoHS3 compliance. This part carries full RoHS3 certification, making it the appropriate choice for designs subject to RoHS3 regulatory requirements.

The RL73H2HR82FTE substitute part is RoHS non-compliant and should be selected only in applications where RoHS compliance is not a design requirement or regulatory constraint. Both parts maintain active product status and are available through TE Connectivity Passive Product distribution channels.

Selection between these two parts depends solely on compliance requirements. All other electrical, mechanical, and thermal characteristics are identical, ensuring functional interchangeability within the scope of the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can RL73H2HR82FTE be used as a direct replacement for RL73H2HR82FTDF in all applications?

A: RL73H2HR82FTE is electrically and mechanically equivalent to RL73H2HR82FTDF across all specified parameters. However, the substitute part is RoHS non-compliant, whereas the primary part is RoHS3 compliant. Use RL73H2HR82FTE only in applications where RoHS compliance is not required.

Q: Are the physical dimensions identical between these two parts?

A: Yes. Both parts share identical dimensions of 0.197" L x 0.098" W (5.00mm x 2.50mm) with a maximum seated height of 0.030" (0.75mm). Both are packaged in the 2010 (5025 Metric) format.

Q: Do these parts have the same temperature performance characteristics?

A: Yes. Both parts operate across the -55°C to 155°C temperature range with a temperature coefficient of ±100ppm/°C.

Q: What is the significance of the base product number RL73H2?

A: The base product number RL73H2 indicates the core resistor design. Both the main part and substitute share this base designation, confirming they are variants of the same fundamental product line within the RL73 and CGS series.

Q: Are both parts available in Tape & Reel packaging?

A: Yes. Both RL73H2HR82FTDF and RL73H2HR82FTE are supplied in Tape & Reel (TR) format, suitable for automated assembly processes.

Q: What is the moisture sensitivity classification for these parts?

A: Both parts carry Moisture Sensitivity Level 1 (Unlimited), indicating no moisture sensitivity constraints during storage or handling.
