Key Parameters

Substitute Part Grouping Explanation

Substitution of the RP2012T-R47-G is determined by strict equivalence across the following parameters:

• Resistance Value: 470 mOhms (exact match required)
• Tolerance: ±2% (exact match required)
• Power Rating: 0.333W / 1/3W (exact match required)
• Package Format: 0805 (2012 Metric) (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)
• Physical Dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm), Height 0.020" max (0.50mm) (exact match required)

The substitute part RL1220S-R47-G meets all mandatory electrical and mechanical parameters. The primary distinction is composition type (thin film versus metal film) and temperature coefficient specification, which do not preclude functional substitution within the defined operating parameters.

Parameter Comparison

Engineering Selection Recommendations

The RL1220S-R47-G serves as a direct functional substitute for the RP2012T-R47-G based on electrical and mechanical parameter equivalence. The substitute part maintains active product status with Susumu, ensuring continued availability and supply chain reliability. Both components satisfy ROHS3 compliance and REACH regulatory requirements, supporting applications with environmental and regulatory constraints.

The RL1220S-R47-G is designated as a current sense thin film resistor, whereas the RP2012T-R47-G is a general-purpose metal film resistor. This distinction reflects application-specific optimization in the substitute part. The temperature coefficient of the substitute (0 / +200ppm/°C) is superior to the main part (0 / +350ppm/°C), providing enhanced temperature stability across the operating range of -55°C to 125°C.

Selection of the RL1220S-R47-G is appropriate for applications requiring 470 mOhms resistance at 1/3W power dissipation in 0805 package format, particularly where current sensing functionality or improved temperature coefficient performance is beneficial.

Frequently Asked Questions (FAQ)

Q: Can RL1220S-R47-G be used as a direct replacement for RP2012T-R47-G?

A: Yes. Both components share identical resistance value (470 mOhms), tolerance (±2%), power rating (0.333W), package format (0805), operating temperature range (-55°C to 125°C), and physical dimensions. Electrical and mechanical compatibility is established.

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

A: Metal film and thin film are distinct resistor construction technologies. The RP2012T-R47-G uses metal film construction, while the RL1220S-R47-G uses thin film construction. Both achieve the specified resistance value and tolerance within the defined operating parameters. Thin film construction in the substitute part provides improved temperature coefficient performance (0 / +200ppm/°C versus 0 / +350ppm/°C).

Q: Are there packaging differences between these parts?

A: Physical package format is identical (0805 / 2012 Metric). Dimensions are 0.079" L x 0.049" W (2.00mm x 1.25mm) with maximum seated height of 0.020" (0.50mm) for both parts. The RL1220S-R47-G is supplied in Tape & Reel (TR) packaging format.

Q: Do both parts meet regulatory requirements?

A: Yes. Both RP2012T-R47-G and RL1220S-R47-G are ROHS3 Compliant and REACH Unaffected. Moisture Sensitivity Level is 1 (Unlimited) for both components, indicating no moisture sensitivity constraints during storage or handling.

Q: Why is the main part listed as obsolete?

A: The RP2012T-R47-G carries obsolete product status. The RL1220S-R47-G maintains active product status with Susumu, ensuring ongoing availability and supply continuity for applications requiring this resistance specification.

Q: What is the current sense feature in the substitute part?

A: The RL1220S-R47-G is optimized for current sensing applications. This designation reflects the thin film construction and superior temperature coefficient, making it suitable for precision current measurement circuits while maintaining full compatibility with the electrical and mechanical specifications of the main part.
