RP2012T-6R8-F Equivalent & Substitute Parts

Part Overview

The RP2012T-6R8-F is a 6.8 Ohms ±1% metal film chip resistor rated at 0.333W (1/3W) in 0805 (2012 Metric) surface mount package manufactured by Susumu. This part is classified as obsolete product status. Equivalent and substitute parts are necessary to maintain design continuity and ensure component availability for production, repair, and redesign applications where the original part is no longer readily procurable through standard distribution channels.

Substitute Part Grouping Explanation

Substitution of the RP2012T-6R8-F is determined by strict equivalence across the following critical parameters:

• Resistance Value: 6.8 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)
• 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 substitute part RL1220S-6R8-F meets all critical electrical and mechanical parameters. Differences in composition (metal film versus thin film) and temperature coefficient do not prevent substitution when the above parameters are identical. The substitute part is manufactured by the same supplier (Susumu) and carries active product status with significantly higher inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The RL1220S-6R8-F is a direct functional equivalent to the RP2012T-6R8-F for applications requiring a 6.8 Ohms ±1% 0.333W 0805 chip resistor. Both parts are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and assembly.

The RL1220S-6R8-F carries active product status with substantially higher inventory availability (47,932 pieces in stock versus 940 pieces for the obsolete RP2012T-6R8-F). The substitute part is supplied in Tape & Reel packaging, suitable for automated assembly processes.

The RL1220S-6R8-F employs thin film composition with a lower temperature coefficient (0 / +200ppm/°C) compared to the metal film composition of the main part (0 / +350ppm/°C). Both parts operate across the identical temperature range of -55°C to 125°C and maintain ±1% tolerance across this range. The improved temperature coefficient of the substitute part provides enhanced stability in temperature-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can RL1220S-6R8-F be used as a direct replacement for RP2012T-6R8-F in existing designs?

A: Yes. Both parts share identical resistance value (6.8 Ohms), tolerance (±1%), power rating (0.333W), package (0805), operating temperature range (-55°C to 125°C), and regulatory compliance status (ROHS3, REACH unaffected). Physical dimensions and termination count are identical, enabling direct substitution on printed circuit boards.

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

A: The RP2012T-6R8-F uses metal film construction while the RL1220S-6R8-F uses thin film construction. Both achieve ±1% tolerance and identical electrical performance across the specified operating temperature range. The thin film variant (RL1220S-6R8-F) exhibits a lower temperature coefficient (0 / +200ppm/°C versus 0 / +350ppm/°C), resulting in improved resistance stability over temperature variations.

Q: Are there packaging differences between these parts?

A: The RL1220S-6R8-F is supplied in Tape & Reel (TR) packaging, which is standard for automated surface mount assembly. The RP2012T-6R8-F packaging format is not specified in available documentation. Both parts use the 0805 (2012 Metric) surface mount package with identical physical dimensions (0.079" L x 0.049" W, 2.00mm x 1.25mm).

Q: Why is the RP2012T-6R8-F classified as obsolete?

A: The RP2012T-6R8-F carries obsolete product status, indicating it is no longer in active production. The RL1220S-6R8-F is the active equivalent from the same manufacturer (Susumu) and is recommended for new designs and ongoing production requirements.

Q: What is the inventory status of these parts?

A: The RP2012T-6R8-F has 940 pieces in stock (obsolete status). The RL1220S-6R8-F has 47,932 pieces in stock (active status), providing significantly greater availability for production and procurement planning.

Q: Are both parts compliant with current environmental and regulatory standards?

A: Yes. Both the RP2012T-6R8-F and RL1220S-6R8-F are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements for electronic component manufacturing and use in regulated markets.
