Substitute Part Grouping Explanation

Substitution of the RP2012T-R22-G is determined by strict equivalence across the following parameters:

• Resistance Value: 220 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)

The substitute part RL1220S-R22-G meets all mandatory electrical and mechanical parameters. The primary difference is composition type (thin film versus metal film) and temperature coefficient specification (0 / +200ppm/°C versus 0 / +350ppm/°C). Both compositions satisfy the stated tolerance and operating conditions within the 0805 package footprint.

Parameter Comparison

Engineering Selection Recommendations

The RL1220S-R22-G serves as a direct functional substitute for the obsolete RP2012T-R22-G. Both components satisfy identical electrical specifications (220 mOhms ±2%, 0.333W) and mechanical requirements (0805 package, identical footprint dimensions). Both components maintain ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements.

The RL1220S-R22-G is classified as active product status, ensuring ongoing availability and supply chain continuity. The thin film composition of the substitute provides a lower temperature coefficient (0 / +200ppm/°C) compared to the metal film composition of the main part (0 / +350ppm/°C), which represents improved temperature stability performance within the specified operating range of -55°C ~ 125°C.

Both components are manufactured by Susumu and share identical physical dimensions and termination configuration, enabling direct board-level substitution without design modification.

Frequently Asked Questions (FAQ)

Q: Can RL1220S-R22-G replace RP2012T-R22-G in existing designs?

A: Yes. Both components meet identical electrical specifications (220 mOhms ±2%, 0.333W rating) and share the same 0805 (2012 Metric) package footprint with identical physical dimensions (0.079" L x 0.049" W, 0.020" max height). Direct substitution is possible without PCB redesign.

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

A: The RP2012T-R22-G uses metal film composition with a temperature coefficient of 0 / +350ppm/°C. The RL1220S-R22-G uses thin film composition with a temperature coefficient of 0 / +200ppm/°C. Both compositions meet the ±2% tolerance specification and operate across the -55°C ~ 125°C temperature range. The thin film variant exhibits lower temperature coefficient drift.

Q: Are both parts RoHS compliant?

A: Yes. Both RP2012T-R22-G and RL1220S-R22-G are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the packaging difference between these parts?

A: The RP2012T-R22-G is supplied in standard packaging format. The RL1220S-R22-G is supplied in Tape & Reel (TR) format. Both components are identical in physical dimensions and electrical performance; packaging format differs only in delivery method.

Q: Why is RP2012T-R22-G classified as obsolete?

A: The RP2012T-R22-G has reached end-of-life status. The RL1220S-R22-G, manufactured by the same supplier (Susumu), is the active equivalent product offering identical electrical and mechanical specifications with improved temperature coefficient performance.

Q: Are there inventory considerations for substitution?

A: The RL1220S-R22-G maintains active production status with 12,975 pieces in stock. The RP2012T-R22-G is obsolete with limited remaining inventory (779 pieces). For new designs and ongoing production, the RL1220S-R22-G is the recommended selection.
