Substitute Part Grouping Explanation

Substitution of the RL73H3AR11FTDF is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part RL73H3AR11FTE maintains identical specifications in the following key areas:

• Resistance value: 110 mOhms
• Tolerance: ±1%
• Power rating: 1W
• Package designation: 2512 (6432 Metric)
• Composition: Thick Film
• Temperature coefficient: ±100ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Current sense functionality
• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)

Both parts are manufactured by TE Connectivity Passive Product and belong to the RL73 and CGS series. The substitute part differs only in packaging designation (Tape & Reel format) and inventory availability, with no variation in electrical performance or mechanical fit.

Parameter Comparison

Engineering Selection Recommendations

Both the RL73H3AR11FTDF and RL73H3AR11FTE are Active products manufactured by TE Connectivity Passive Product and carry identical ROHS3 compliance and REACH Unaffected certifications. Selection between these parts is based on packaging and inventory requirements rather than electrical or mechanical performance differences.

The RL73H3AR11FTDF is supplied in Tape & Reel (TR) packaging with 1857 pieces currently in stock. The RL73H3AR11FTE is also supplied in Tape & Reel (TR) packaging with 24126 pieces in stock, providing greater availability for high-volume applications.

Both parts satisfy identical circuit requirements for 110 mOhms ±1% 1W current sense applications operating within the -55°C to 155°C temperature range. Component selection should be determined by supply chain availability and project lead time requirements.
