Substitute Part Grouping Explanation

Substitution of the RP2012T-R33-F is determined by strict equivalence across the following parameters:

• Resistance Value: 330 mOhms exact match required
• Tolerance: ±1% exact match required
• Power Rating: 0.333W (1/3W) minimum required
• Package / Case: 0805 (2012 Metric) exact match required
• Operating Temperature Range: -55°C ~ 125°C minimum required
• RoHS Compliance: ROHS3 Compliant required
• Moisture Sensitivity Level: 1 (Unlimited) required
• Physical Dimensions: 0.079" L x 0.049" W (2.00mm x 1.25mm) exact match required

The RL1220S-R33-F meets all mandatory substitution criteria. Composition differs (thin film versus metal film) and temperature coefficient differs (0/+200ppm/°C versus 0/+350ppm/°C), however these variations remain within acceptable electrical performance boundaries for the specified resistance, tolerance, and power rating classification.

Parameter Comparison

Engineering Selection Recommendations

The RL1220S-R33-F is a direct functional substitute for the RP2012T-R33-F. Both components are manufactured by Susumu and maintain identical electrical specifications for resistance value, tolerance, power rating, and operating temperature range. Both components satisfy ROHS3 compliance and REACH unaffected status requirements.

The RL1220S-R33-F carries active product status, ensuring continued availability and supply chain reliability compared to the obsolete RP2012T-R33-F. The substitute part is available in Tape & Reel (TR) packaging format with significantly higher inventory levels (97,274 pieces in stock versus 654 pieces for the main part).

The composition difference (thin film versus metal film) and improved temperature coefficient (0/+200ppm/°C versus 0/+350ppm/°C) in the substitute part represent enhanced performance characteristics. Both parts maintain identical physical dimensions and termination configuration, ensuring direct mechanical and electrical compatibility in 0805 package footprints.

Frequently Asked Questions (FAQ)

Q: Can the RL1220S-R33-F be used as a direct replacement for the RP2012T-R33-F in existing designs?

A: Yes. Both components share identical resistance value (330 mOhms), tolerance (±1%), power rating (0.333W), package (0805), operating temperature range (-55°C ~ 125°C), and physical dimensions. The substitute part is electrically and mechanically compatible.

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

A: Composition is specified in the part parameters. Metal film (RP2012T-R33-F) and thin film (RL1220S-R33-F) are distinct manufacturing technologies. Both meet the specified resistance, tolerance, and power rating requirements for this application.

Q: Does the temperature coefficient difference affect substitution suitability?

A: Both parts operate within the specified temperature range of -55°C ~ 125°C. The RL1220S-R33-F exhibits a lower temperature coefficient (0/+200ppm/°C versus 0/+350ppm/°C), which represents improved stability across the operating temperature range.

Q: Are there packaging format differences between these parts?

A: The RP2012T-R33-F packaging format is not specified in the provided data. The RL1220S-R33-F is supplied in Tape & Reel (TR) format. Both parts use identical 0805 (2012 Metric) package / case specification.

Q: What is the current sense feature in the RL1220S-R33-F?

A: The RL1220S-R33-F is designated as a current sense thin film resistor. This feature is specified in the part parameters. Both components maintain identical electrical specifications for the stated resistance, tolerance, and power rating.

Q: Why is the RP2012T-R33-F marked as obsolete?

A: Product status is provided in the component data. The RP2012T-R33-F is classified as obsolete. The RL1220S-R33-F maintains active product status, ensuring ongoing availability and supply continuity.

Q: Are both parts RoHS and REACH compliant?

A: Yes. Both the RP2012T-R33-F and RL1220S-R33-F are ROHS3 Compliant and REACH Unaffected. Both carry EAR99 ECCN classification and 8533.21.0030 HTSUS code.
