RT1206CRE07300RL Equivalent & Substitute Parts

Part Overview

The RT1206CRE07300RL is a 300 Ohm thin film chip resistor in 1206 package format, manufactured by YAGEO. This surface mount device delivers 0.25W power rating with ±0.25% tolerance and operates across -55°C to 155°C. The part is Active status and ROHS3 compliant, making it suitable for general industrial and commercial applications requiring precision resistive elements.

Substitute parts become necessary when inventory constraints occur, when design upgrades to tighter tolerances are required, or when automotive-grade reliability certifications are mandated for specific applications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206CRE07300RL is determined by the following mandatory parameters:

• Resistance value: 300 Ohms (exact match required)
• Package format: 1206 (3216 Metric) with compatible footprint dimensions
• Power rating: 0.25W minimum
• Composition: Thin film construction
• Operating temperature range: -55°C to 155°C minimum coverage
• RoHS3 compliance and MSL Level 1 rating

The two qualified substitutes meet these core requirements while offering enhanced specifications. RT1206BRD07300RL provides improved tolerance (±0.1% vs ±0.25%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C) within the same YAGEO RT series. ERA-8AEB301V delivers equivalent electrical performance with automotive AEC-Q200 qualification for applications requiring automotive-grade reliability.

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD07300RL serves as a direct upgrade path within the YAGEO RT series, offering superior tolerance and temperature stability while maintaining identical package footprint and power characteristics. This substitute is appropriate for designs requiring tighter resistive tolerances without introducing supply chain complexity or qualification changes.

ERA-8AEB301V is selected when automotive-grade reliability is mandated. The AEC-Q200 qualification ensures compliance with automotive industry standards for component reliability and environmental stress testing. Physical dimensions show minor variation (0.126" L vs 0.122" L; 0.028" H vs 0.026" H), requiring PCB layout verification before implementation.

Both substitutes maintain Active product status and full RoHS3 compliance, ensuring long-term availability and regulatory alignment with the original part.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD07300RL be used as a direct replacement on existing PCBs designed for RT1206CRE07300RL?

A: Yes. Both parts share identical 1206 package footprint, power rating, and operating temperature range. The improved tolerance and temperature coefficient of RT1206BRD07300RL represent enhanced performance with no layout modifications required.

Q: What is the primary difference between RT1206BRD07300RL and ERA-8AEB301V?

A: Both offer ±0.1% tolerance and ±25ppm/°C temperature coefficient. ERA-8AEB301V includes AEC-Q200 automotive qualification; RT1206BRD07300RL does not. Physical dimensions differ slightly: ERA-8AEB301V is 0.126" L × 0.028" H versus RT1206BRD07300RL at 0.122" L × 0.026" H. Select ERA-8AEB301V for automotive applications; RT1206BRD07300RL for general industrial use.

Q: Is ERA-8AEB301V compatible with standard 1206 PCB footprints?

A: ERA-8AEB301V uses 1206 (3216 Metric) package with slightly larger dimensions than standard 1206 parts. Verify PCB layout clearances and solder pad dimensions before substitution. The part remains mechanically compatible with 1206 footprints but may require design review for high-density layouts.

Q: Are all three parts RoHS3 compliant?

A: Yes. RT1206CRE07300RL, RT1206BRD07300RL, and ERA-8AEB301V are all ROHS3 compliant with MSL Level 1 (Unlimited) moisture sensitivity rating, ensuring regulatory compliance and extended shelf life without special storage requirements.

Q: Which substitute should be selected for cost optimization?

A: RT1206BRD07300RL provides the best cost-to-performance ratio for non-automotive applications, delivering superior tolerance and temperature stability over the original part. ERA-8AEB301V carries higher cost due to automotive qualification but is mandatory for AEC-Q200 compliant designs.
