RT1206FRE07124RL Equivalent & Substitute Parts

Part Overview

The RT1206FRE07124RL is a 124 Ohms ±1% thin film chip resistor in 1206 (3216 Metric) package rated for 0.25W power dissipation. Manufactured by YAGEO, this component is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity level (MSL 1). Substitute parts are identified when equivalent electrical performance and mechanical compatibility are required, particularly when higher tolerance specifications or automotive-grade certifications become necessary for application requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07124RL is determined by the following mandatory parameters:

• Resistance value: 124 Ohms (exact match required)
• Package type: 1206 (3216 Metric) form factor
• Power rating: 0.25W minimum
• Composition: Thin film construction
• Operating temperature range: -55°C to 155°C minimum
• RoHS compliance: ROHS3 Compliant

Tolerance and temperature coefficient may vary within acceptable ranges for general-purpose applications. Substitute parts identified meet all mandatory electrical and mechanical parameters while offering enhanced specifications in tolerance accuracy or automotive-grade certifications.

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD07124RL serves as a direct upgrade within the YAGEO RT series, offering improved tolerance specification (±0.1% versus ±1%) and reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical package geometry and power rating. This substitute is suitable for applications requiring tighter resistance accuracy without automotive qualification requirements.

ERA-8AEB1240V provides equivalent electrical performance with the addition of AEC-Q200 automotive qualification. This Panasonic component is specified for automotive applications where reliability standards and temperature cycling performance are mandated. Physical dimensions show minor variation (0.126" L x 0.063" W versus 0.122" L x 0.063" W and 0.028" height versus 0.026" height), requiring verification of PCB layout clearances in space-constrained designs.

Both substitute parts maintain ROHS3 compliance and unlimited moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage protocols.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD07124RL replace RT1206FRE07124RL in any application?

A: Yes, RT1206BRD07124RL is electrically and mechanically compatible. The improved tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C) represent enhanced specifications that do not create incompatibility with designs specified for ±1% tolerance.

Q: What is the primary difference between the two YAGEO substitutes?

A: RT1206BRD07124RL is a standard thin film resistor with tighter tolerance. ERA-8AEB1240V is an automotive-grade component (AEC-Q200 rated) from Panasonic, suitable for applications requiring automotive reliability standards.

Q: Are there physical dimension differences that affect PCB layout?

A: ERA-8AEB1240V has slightly larger dimensions (0.126" L x 0.063" W x 0.028" H) compared to RT1206FRE07124RL (0.122" L x 0.063" W x 0.026" H). Standard 1206 footprints accommodate both, but designs with minimal clearance should be verified.

Q: Do all substitute parts maintain the same operating temperature range?

A: Yes, all parts operate across -55°C to 155°C. Temperature coefficient values differ, affecting long-term stability in temperature-cycling environments.

Q: Are packaging and moisture sensitivity specifications identical across all three parts?

A: Yes, all three parts are supplied in Tape & Reel (TR) packaging with MSL 1 (Unlimited) rating and ROHS3 compliance.
