RT1206FRE072K1L Equivalent & Substitute Parts

Part Overview

The RT1206FRE072K1L is a 2.1 kOhms ±1% thin film chip resistor in 1206 (3216 Metric) package format, rated for 0.25W (1/4W) power dissipation. Manufactured by YAGEO under the RT series, this component is actively produced and widely used in general-purpose electronic applications requiring standard tolerance resistive elements. Substitute parts are identified to provide alternative sourcing options when the primary part becomes unavailable or when design requirements necessitate enhanced performance characteristics such as improved tolerance or automotive-grade qualification.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT1206FRE072K1L are qualified based on the following critical parameters:

• Resistance Value: Must be 2.1 kOhms
• Package / Case: Must be 1206 (3216 Metric)
• Power Rating: Must be 0.25W (1/4W) minimum
• Composition: Must be Thin Film
• Operating Temperature Range: Must support -55°C ~ 155°C
• Termination Count: Must be 2 terminations
• RoHS Compliance: Must be ROHS3 Compliant

The ERA-8AEB2101V qualifies as a direct substitute because it meets all mandatory electrical and mechanical parameters. Enhanced specifications such as improved tolerance (±0.1% vs ±1%) and automotive AEC-Q200 qualification represent performance upgrades rather than compatibility restrictions.

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE072K1L and ERA-8AEB2101V are active production components with ROHS3 compliance and unlimited moisture sensitivity rating, making them suitable for standard industrial applications.

The ERA-8AEB2101V provides enhanced specifications through tighter tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), along with automotive AEC-Q200 qualification. Selection between these parts depends on application requirements: the RT1206FRE072K1L is appropriate for general-purpose circuits where standard tolerance is acceptable, while the ERA-8AEB2101V is preferred for precision analog circuits, automotive systems, or applications requiring superior temperature stability.

Physical dimensions show minor variations within the 1206 package specification, with the ERA-8AEB2101V measuring slightly larger (3.20mm vs 3.10mm length, 0.70mm vs 0.65mm height). These differences remain within standard 1206 package tolerances and do not affect PCB footprint compatibility.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB2101V be used as a direct replacement for RT1206FRE072K1L?

A: Yes. Both components share identical resistance value (2.1 kOhms), power rating (0.25W), package format (1206), composition (thin film), and operating temperature range (-55°C ~ 155°C). The ERA-8AEB2101V meets all mandatory electrical and mechanical compatibility requirements.

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

A: The ERA-8AEB2101V offers improved tolerance (±0.1% vs ±1%), lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), and automotive AEC-Q200 qualification. Physical dimensions show minor variations within standard 1206 tolerances. These represent performance enhancements rather than compatibility limitations.

Q: Are there PCB layout considerations when substituting these parts?

A: Both components use the same 1206 (3216 Metric) package with 2 terminations. Dimensional variations (length 3.10mm vs 3.20mm, height 0.65mm vs 0.70mm) fall within standard 1206 package specifications and do not require PCB footprint modification.

Q: Which part should be selected for precision applications?

A: The ERA-8AEB2101V is recommended for precision circuits due to its ±0.1% tolerance and ±25ppm/°C temperature coefficient, compared to the RT1206FRE072K1L's ±1% tolerance and ±50ppm/°C coefficient.

Q: Are both parts RoHS compliant?

A: Yes. Both RT1206FRE072K1L and ERA-8AEB2101V are ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).
