Substitute Part Grouping Explanation

Substitution of the RP2012S-220-F is determined by strict equivalence across the following critical parameters:

• Resistance Value: 22 Ohms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.333W / 1/3W (exact match required)
• Package: 0805 (2012 Metric) (exact match required)
• Temperature Coefficient: 0 / +200ppm/°C (exact match required)
• Operating Temperature Range: -55°C ~ 125°C (exact match required)
• Regulatory Compliance: ROHS3 Compliant, REACH Unaffected (exact match required)
• Moisture Sensitivity Level: 1 (Unlimited) (exact match required)

The RL1220S-220-F meets all substitution criteria. While the composition differs (thin film versus metal film) and the series designation changes (RL versus RP), the electrical performance parameters, mechanical dimensions, and regulatory compliance remain equivalent. The RL1220S-220-F is manufactured by Susumu and maintains active product status with higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The RL1220S-220-F is a direct electrical and mechanical substitute for the RP2012S-220-F. Both components satisfy identical electrical specifications: 22 Ohms resistance at ±1% tolerance, 0.333W power rating, and identical temperature coefficient and operating range. Both components are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements.

The primary distinction is product lifecycle status: the RP2012S-220-F is obsolete, while the RL1220S-220-F maintains active status with significantly higher inventory availability (33,524 pieces versus 1,131 pieces). The RL1220S-220-F is supplied in Tape & Reel packaging, which is standard for production environments.

The composition difference (thin film versus metal film) does not affect substitution validity, as both film types deliver the specified electrical performance parameters within the stated tolerance and temperature coefficient ranges.

Frequently Asked Questions (FAQ)

Q: Can the RL1220S-220-F replace the RP2012S-220-F in existing designs?

A: Yes. The RL1220S-220-F meets all electrical and mechanical specifications of the RP2012S-220-F. Both components deliver 22 Ohms ±1% resistance at 0.333W power rating in identical 0805 (2012 Metric) package dimensions. Regulatory compliance (ROHS3, REACH) is equivalent.

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

A: Both metal film and thin film resistors deliver the specified electrical performance within the stated tolerance and temperature coefficient parameters. The composition difference does not affect substitution validity for applications requiring the specified 22 Ohms ±1% at 0.333W rating.

Q: Are the physical dimensions identical?

A: Yes. Both components are 0.079" L x 0.049" W (2.00mm x 1.25mm) with maximum seated height of 0.020" (0.50mm). Both use 2 terminations and are fully compatible with 0805 (2012 Metric) footprints.

Q: What is the difference in packaging?

A: The RP2012S-220-F is supplied in bulk packaging, while the RL1220S-220-F is supplied in Tape & Reel (TR) format. Tape & Reel packaging is standard for automated assembly processes and provides higher inventory availability.

Q: Why is the RP2012S-220-F marked as obsolete?

A: Obsolete status indicates the part is no longer in active production. The RL1220S-220-F provides equivalent electrical and mechanical performance with active product status and higher availability.

Q: Are both components suitable for current sense applications?

A: The RL1220S-220-F is designated with current sense features. Both components deliver the specified 22 Ohms ±1% resistance and are suitable for applications requiring this resistance value and power rating.
