Substitute Part Grouping Explanation

Substitution of the RP2012T-100-G is based on strict equivalence across the following parameters:

Electrical Parameters (Mandatory Match):

• Resistance value: 10 Ohms
• Tolerance: ±2%
• Power dissipation rating: 0.333W (1/3W)
• Operating temperature range: -55°C ~ 125°C

Mechanical Parameters (Mandatory Match):

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

Compliance Parameters (Mandatory Match):

• RoHS3 compliance
• Moisture Sensitivity Level 1
• REACH unaffected status
• ECCN and HTSUS classifications

The RL1220S-100-G qualifies as a direct substitute based on full alignment with all critical parameters. Composition differences (metal film versus thin film) and temperature coefficient variations do not preclude substitution when electrical performance requirements are met within specified tolerances.

Engineering Selection Recommendations

The RL1220S-100-G is a direct functional equivalent to the RP2012T-100-G for applications requiring a 10 Ohm ±2% resistor in 0805 package format. Selection of the substitute part is supported by the following factors:

Product Status Advantage: The RL1220S-100-G maintains active product status with 748 units in stock, compared to the obsolete RP2012T-100-G. This ensures long-term availability and supply chain continuity.

Electrical Equivalence: Both parts deliver identical resistance, tolerance, power rating, and operating temperature specifications. The RL1220S-100-G composition (thin film) and lower temperature coefficient (+200ppm/°C versus +350ppm/°C) represent performance enhancements suitable for precision applications.

Compliance Alignment: Both parts satisfy ROHS3, REACH, and MSL requirements with matching ECCN and HTSUS classifications, ensuring regulatory compliance across manufacturing and distribution channels.

Mechanical Compatibility: Identical package dimensions, footprint, and termination configuration enable direct board-level substitution without layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the RL1220S-100-G replace the RP2012T-100-G in existing designs?

A: Yes. Both parts share identical electrical specifications (10 Ohms ±2%, 0.333W), operating temperature range (-55°C ~ 125°C), and 0805 package dimensions. Direct substitution is supported at the component level.

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

A: The RP2012T-100-G uses metal film construction with a temperature coefficient of 0 / +350ppm/°C. The RL1220S-100-G uses thin film construction with a temperature coefficient of 0 / +200ppm/°C. Both compositions meet the specified tolerance and operating range. The thin film variant offers lower temperature coefficient drift, beneficial for temperature-sensitive applications.

Q: Are there packaging differences between these parts?

A: The RL1220S-100-G is supplied in Tape & Reel (TR) format. The RP2012T-100-G packaging is not specified in available data. Both parts use identical 0805 (2012 Metric) surface mount package format suitable for automated assembly.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the RP2012T-100-G and RL1220S-100-G are ROHS3 compliant, REACH unaffected, and classified as MSL 1 (unlimited moisture sensitivity). Both share identical ECCN (EAR99) and HTSUS (8533.21.0030) classifications.

Q: Why is the RP2012T-100-G listed as obsolete?

A: The RP2012T-100-G has been discontinued by the manufacturer. The RL1220S-100-G is the active equivalent part, ensuring continued availability for new production and design implementations.

Q: Can I use the RL1220S-100-G in high-precision applications?

A: The RL1220S-100-G is designated as a current sense thin film resistor with a lower temperature coefficient (+200ppm/°C) compared to the metal film RP2012T-100-G (+350ppm/°C). This characteristic makes it suitable for precision measurement and current sensing applications where temperature stability is required.

Q: What is the current inventory status?

A: The RP2012T-100-G has 814 units in stock (obsolete status). The RL1220S-100-G has 748 units in stock (active status). For new designs, the RL1220S-100-G is recommended due to active product status and assured long-term availability.
