RL73H2HR91FTDF Equivalent & Substitute Parts

Part Overview

The RL73H2HR91FTDF is a 910 mOhms ±1% 0.75W chip resistor manufactured by TE Connectivity Passive Product in the 2010 (5025 Metric) package. This current sense thick film resistor operates across a temperature range of -55°C to 155°C and is designed for precision current measurement applications. The part maintains Active product status and is ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications, mechanical dimensions, and compliance certifications are maintained across alternative packaging configurations or manufacturing batches within the same product series.

Substitute Part Grouping Explanation

Substitution eligibility for the RL73H2HR91FTDF is determined by strict equivalence across the following parameters:

• Electrical Specifications: Resistance value (910 mOhms), tolerance (±1%), power rating (0.75W), and temperature coefficient (±100ppm/°C) must be identical
• Package Compatibility: 2010 (5025 Metric) package with matching physical dimensions (0.197" L x 0.098" W, 0.030" max height) and two terminations
• Material Composition: Thick film construction for current sense applications
• Compliance & Certifications: ROHS3 compliance, MSL 1 rating, and REACH unaffected status must be maintained
• Product Series: Parts must belong to the RL73 or CGS series from TE Connectivity Passive Product

The substitute part RL73H2HR91FTE meets all substitution criteria through identical electrical and mechanical specifications within the same manufacturer product line.

Parameter Comparison

Engineering Selection Recommendations

Both RL73H2HR91FTDF and RL73H2HR91FTE are Active products from TE Connectivity Passive Product with identical electrical and mechanical specifications. Selection between these parts is based on packaging configuration and inventory availability rather than functional differences.

RL73H2HR91FTDF (Tape & Reel packaging) is suitable for automated assembly processes requiring reel-based component feeding.

RL73H2HR91FTE (Tape & Reel packaging) provides equivalent functionality with identical compliance certifications (ROHS3, MSL 1, REACH unaffected).

Both parts maintain the same base product number (RL73H2) and are fully interchangeable in applications requiring 910 mOhms ±1% current sense resistors in the 2010 package with 0.75W power rating across the -55°C to 155°C operating range.

Frequently Asked Questions (FAQ)

Q: Can RL73H2HR91FTE be used as a direct replacement for RL73H2HR91FTDF?

A: Yes. Both parts are electrically and mechanically identical with matching resistance (910 mOhms), tolerance (±1%), power rating (0.75W), package dimensions (2010/5025 Metric), and compliance certifications. They are interchangeable in all applications.

Q: What is the difference between RL73H2HR91FTDF and RL73H2HR91FTE?

A: The parts differ only in packaging designation within the same Tape & Reel (TR) format. All electrical specifications, mechanical dimensions, and compliance ratings are identical. The difference reflects manufacturing batch or supplier configuration rather than functional capability.

Q: Are these parts suitable for high-temperature applications?

A: Yes. Both parts operate across -55°C to 155°C with a temperature coefficient of ±100ppm/°C, supporting applications requiring extended temperature range operation.

Q: What is the current sense application for these resistors?

A: These thick film resistors are designed for precision current measurement circuits. The 910 mOhms resistance value with ±1% tolerance and ±100ppm/°C temperature coefficient provides stable current sensing across the specified operating temperature range.

Q: Are these parts RoHS compliant?

A: Yes. Both RL73H2HR91FTDF and RL73H2HR91FTE are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating and REACH unaffected status.

Q: What is the physical footprint of the 2010 package?

A: The 2010 (5025 Metric) package measures 0.197" length x 0.098" width (5.00mm x 2.50mm) with a maximum seated height of 0.030" (0.75mm), suitable for standard PCB assembly processes.
