RP2012S-470-F Equivalent & Substitute Parts

Part Overview

The RP2012S-470-F is a 47 Ohm ±1% metal film chip resistor rated at 0.333W (1/3W) in 0805 (2012 Metric) surface mount package. This component is manufactured by Susumu and is classified as obsolete product status. The part is RoHS3 compliant with unlimited moisture sensitivity level (MSL 1) and operates across the temperature range of -55°C to 125°C. Due to its obsolete status, equivalent substitute parts with matching electrical and mechanical specifications are necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RP2012S-470-F is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 47 Ohms
• Tolerance: ±1%
• Power rating: 0.333W (1/3W)
• Temperature coefficient: 0 / +200ppm/°C
• Operating temperature range: -55°C ~ 125°C

Mechanical Parameters:

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

Compliance Parameters:

• RoHS3 compliance
• Moisture sensitivity level: 1 (Unlimited)
• REACH unaffected status

The substitute part RL1220S-470-F meets all electrical and mechanical requirements for direct substitution. The primary difference is composition type (thin film versus metal film) and active product status, which does not affect functional equivalence for the specified electrical parameters.
