Key Parameters

Substitute Part Grouping Explanation

Substitution of the RP2012T-R82-F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 820 mOhms (0.82 Ohm)
• Tolerance: ±1%
• Power rating: 0.333W (1/3W)
• Operating temperature range: -55°C to 125°C

Mechanical Parameters:

• Package type: 0805 (2012 Metric)
• Physical dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm)
• Height seated (max): 0.020" (0.50mm)
• Number of terminations: 2

Compliance Parameters:

• RoHS3 compliance
• Moisture Sensitivity Level 1
• REACH unaffected status

The RL1220S-R82-F qualifies as a direct substitute based on matching all electrical, mechanical, and compliance parameters. Composition differences (metal film versus thin film) and temperature coefficient variations do not preclude substitution when electrical performance requirements are met within the specified tolerance and power rating.

Parameter Comparison

Engineering Selection Recommendations

The RL1220S-R82-F is a direct functional equivalent to the obsolete RP2012T-R82-F. Both components meet identical electrical specifications (820 mOhms ±1%, 0.333W) and mechanical requirements (0805 package, identical footprint dimensions). Both components satisfy ROHS3 compliance, REACH unaffected status, and MSL 1 moisture sensitivity requirements.

The RL1220S-R82-F carries active product status from Susumu, ensuring ongoing availability and supply chain continuity. The substitute part is available in Tape & Reel (TR) packaging format, suitable for automated assembly processes.

The RL1220S-R82-F features current sense thin film composition with improved temperature coefficient performance (0 / +200ppm/°C versus 0 / +350ppm/°C), providing enhanced stability across the full operating temperature range of -55°C to 125°C.

Frequently Asked Questions (FAQ)

Q: Can the RL1220S-R82-F be used as a direct replacement for the RP2012T-R82-F in existing designs?

A: Yes. Both components share identical resistance value (820 mOhms), tolerance (±1%), power rating (0.333W), package type (0805), and physical dimensions. Electrical performance and PCB footprint compatibility are fully maintained.

Q: What is the difference between metal film and thin film composition in these resistors?

A: The RP2012T-R82-F uses metal film construction, while the RL1220S-R82-F uses thin film construction. Both compositions meet the specified electrical parameters. The thin film variant in the RL1220S-R82-F provides a lower temperature coefficient (0 / +200ppm/°C versus 0 / +350ppm/°C), resulting in improved resistance stability across temperature variations.

Q: Are there packaging differences between these parts?

A: The RP2012T-R82-F packaging format is not specified in the provided data. The RL1220S-R82-F is supplied in Tape & Reel (TR) format. Both components use the 0805 (2012 Metric) package with identical physical dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm).

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RP2012T-R82-F and RL1220S-R82-F are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Why is the RP2012T-R82-F listed as obsolete?

A: The RP2012T-R82-F carries obsolete product status designation. The RL1220S-R82-F is an active product from the same manufacturer, providing equivalent electrical and mechanical performance with assured long-term availability.

Q: What is the operating temperature range for both components?

A: Both the RP2012T-R82-F and RL1220S-R82-F operate across the identical temperature range of -55°C to 125°C.
