RT1206FRD07124RL Equivalent & Substitute Parts

Part Overview

The RT1206FRD07124RL is a 124 Ohm ±1% thin film chip resistor in 1206 (3216 Metric) package manufactured by YAGEO. This surface mount device is rated for 0.25W (1/4W) power dissipation with an operating temperature range of -55°C to 155°C. The part is currently active in production with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent resistance values, package dimensions, and electrical ratings are maintained while offering improved tolerance specifications or enhanced environmental performance characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT1206FRD07124RL are qualified based on the following criteria:

• Identical resistance value: 124 Ohms
• Compatible package: 1206 (3216 Metric) with equivalent footprint dimensions
• Equal or superior tolerance: ±1% or better
• Equal or greater power rating: 0.25W minimum
• Matching or superior temperature coefficient: ±25ppm/°C
• Operating temperature range: -55°C minimum to 155°C minimum
• Thin film composition
• ROHS3 compliance
• MSL 1 rating

Three substitute parts meet these criteria with varying enhancements in tolerance, power rating, or automotive qualification.

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD07124RL offers improved tolerance (±0.1% versus ±1%) while maintaining identical power rating and temperature specifications. This substitute is suitable for applications requiring tighter resistance accuracy within the same thermal and power envelope.

TNPW1206124RBEEA provides enhanced power rating (0.52W versus 0.25W), extended operating temperature range to 175°C, and AEC-Q200 automotive qualification with anti-sulfur and moisture-resistant properties. This substitute is appropriate for automotive applications or designs requiring higher thermal margin.

ERA-8AEB1240V combines improved tolerance (±0.1%), AEC-Q200 automotive qualification, and manufacturer recommendation status. This substitute maintains the original power rating and temperature range while providing automotive-grade reliability.

All three substitutes maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD07124RL be used as a direct replacement for RT1206FRD07124RL?

A: Yes. Both parts share identical resistance, power rating, package dimensions, temperature coefficient, and operating temperature range. The RT1206BRD07124RL offers superior tolerance specification (±0.1% versus ±1%) with no performance degradation.

Q: What is the primary advantage of TNPW1206124RBEEA?

A: TNPW1206124RBEEA provides doubled power rating (0.52W versus 0.25W), extended maximum operating temperature (175°C versus 155°C), and AEC-Q200 automotive qualification. Anti-sulfur and moisture-resistant properties add environmental robustness.

Q: Are ERA-8AEB1240V and RT1206FRD07124RL footprint compatible?

A: Yes. Both use 1206 (3216 Metric) package with equivalent PCB footprints. Dimensional variations (0.126" L x 0.063" W for ERA-8AEB1240V versus 0.122" L x 0.063" W for RT1206FRD07124RL) are within standard 1206 package tolerance and do not affect assembly compatibility.

Q: Which substitute is recommended for automotive applications?

A: Both TNPW1206124RBEEA and ERA-8AEB1240V carry AEC-Q200 automotive qualification. Selection depends on thermal requirements: ERA-8AEB1240V for standard automotive environments, TNPW1206124RBEEA for high-temperature or high-power dissipation scenarios.

Q: Do all substitutes maintain RoHS3 compliance?

A: Yes. RT1206BRD07124RL, TNPW1206124RBEEA, and ERA-8AEB1240V are all ROHS3 compliant with MSL 1 rating, ensuring compatibility with standard lead-free PCB assembly processes.

Q: What tolerance specification should be selected for precision analog circuits?

A: For applications requiring tighter tolerance control, RT1206BRD07124RL, TNPW1206124RBEEA, or ERA-8AEB1240V (all ±0.1%) are appropriate. The original RT1206FRD07124RL (±1%) is suitable for general-purpose applications where tolerance stack-up is not critical.
