RT1206FRE0721R5L Equivalent & Substitute Parts

Part Overview

The RT1206FRE0721R5L is a 21.5 Ohm thin film chip resistor manufactured by YAGEO in the 1206 (3216 Metric) package format. This component is rated for 0.25W (1/4W) power dissipation with ±1% tolerance and operates across the temperature range of -55°C to 155°C. The part maintains Active product status with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained within the specified parameter constraints.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE0721R5L is determined by the following mandatory parameters:

• Resistance value: 21.5 Ohms (exact match required)
• Package format: 1206 (3216 Metric) (exact match required)
• Power rating: 0.25W minimum (equal or greater acceptable)
• Composition: Thin Film (exact match required)
• Operating temperature range: -55°C to 155°C minimum (equal or wider range acceptable)
• RoHS3 compliance: Required
• Moisture sensitivity: MSL 1 or better (lower MSL values acceptable)

The RT1206BRD0721R5L qualifies as a direct substitute based on these criteria. Enhanced tolerance (±0.1% versus ±1%) and improved temperature coefficient (±25ppm/°C versus ±50ppm/°C) represent performance upgrades that maintain full backward compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE0721R5L and RT1206BRD0721R5L maintain Active product status with full RoHS3 compliance and REACH unaffected designation. The RT1206BRD0721R5L provides enhanced tolerance specification (±0.1% versus ±1%) and superior temperature coefficient performance (±25ppm/°C versus ±50ppm/°C) while maintaining identical mechanical footprint, power rating, and operating temperature range. Selection between these parts depends on circuit tolerance requirements and thermal stability specifications. Both components are suitable for direct substitution in applications where the original RT1206FRE0721R5L is specified.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD0721R5L replace RT1206FRE0721R5L in existing designs?

A: Yes. Both components share identical resistance value (21.5 Ohms), package format (1206), power rating (0.25W), and operating temperature range (-55°C to 155°C). The RT1206BRD0721R5L offers improved tolerance and temperature coefficient specifications, making it a direct upgrade.

Q: What are the key differences between these two parts?

A: The primary differences are tolerance specification (±0.1% versus ±1%) and temperature coefficient (±25ppm/°C versus ±50ppm/°C). The RT1206BRD0721R5L provides tighter tolerance and better thermal stability. All other electrical and mechanical parameters remain identical.

Q: Are the physical dimensions identical?

A: Yes. Both components use the 1206 (3216 Metric) package with identical dimensions of 0.122" L x 0.063" W (3.10mm x 1.60mm) and maximum seated height of 0.026" (0.65mm). PCB layout and assembly processes require no modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both RT1206FRE0721R5L and RT1206BRD0721R5L are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected for precision applications?

A: The RT1206BRD0721R5L is suitable for applications requiring tighter tolerance control and improved temperature stability due to its ±0.1% tolerance and ±25ppm/°C temperature coefficient specifications.
