RT1206CRE0791RL Equivalent & Substitute Parts

Part Overview

The RT1206CRE0791RL is a 91 Ohm thin film chip resistor manufactured by YAGEO in the 1206 (3216 Metric) package format. This component is rated for 0.25W power dissipation with ±0.25% tolerance and operates across the -55°C to 155°C temperature range. The part maintains Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent resistance values, package dimensions, power ratings, and operating temperature ranges align with the original specification, enabling direct functional replacement in circuit applications.

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206CRE0791RL is determined by the following critical parameters:

• Resistance value: 91 Ohms (exact match required)
• Package format: 1206 (3216 Metric) with compatible physical dimensions
• Power rating: 0.25W minimum
• Operating temperature range: -55°C to 155°C minimum coverage
• Composition: Thin film construction
• Compliance: ROHS3 and REACH status alignment

The ERA-8AEB910V qualifies as a direct substitute based on matching all core electrical and mechanical parameters. Enhanced specifications (±0.1% tolerance, ±25ppm/°C temperature coefficient, AEC-Q200 automotive qualification) represent performance improvements over the original part while maintaining full functional compatibility.

Parameter Comparison

Engineering Selection Recommendations

The ERA-8AEB910V serves as a qualified substitute for the RT1206CRE0791RL in applications requiring 91 Ohm thin film resistors in 1206 package format. Both parts maintain identical resistance values, power ratings, operating temperature ranges, and compliance certifications (ROHS3, REACH Unaffected).

The ERA-8AEB910V provides tighter tolerance specification (±0.1% versus ±0.25%) and improved temperature stability (±25ppm/°C versus ±50ppm/°C), making it suitable for precision circuit applications. The AEC-Q200 automotive qualification of the ERA-8AEB910V extends applicability to automotive-grade designs without additional qualification requirements.

Selection between these parts depends on application-specific tolerance and temperature stability requirements. Both parts are Active status components with established supply availability.

Frequently Asked Questions (FAQ)

Q: Can the ERA-8AEB910V directly replace the RT1206CRE0791RL in existing designs?

A: Yes. Both parts share identical 91 Ohm resistance, 0.25W power rating, 1206 package format, and -55°C to 155°C operating temperature range. Physical dimensions and electrical performance are compatible for direct PCB substitution.

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

A: The ERA-8AEB910V offers improved tolerance (±0.1% versus ±0.25%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). The ERA-8AEB910V includes AEC-Q200 automotive qualification, while the RT1206CRE0791RL does not specify automotive rating.

Q: Are there package dimension differences between these parts?

A: Both parts use the 1206 (3216 Metric) package. The RT1206CRE0791RL measures 0.122" L × 0.063" W with 0.026" maximum seated height. The ERA-8AEB910V measures 0.126" L × 0.063" W with 0.028" maximum seated height. These minor dimensional variations remain within standard 1206 package tolerances and do not affect PCB layout compatibility.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both parts are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected for new designs?

A: Selection depends on tolerance and temperature stability requirements. For applications requiring ±0.25% tolerance and standard temperature performance, either part is suitable. For precision applications or automotive designs, the ERA-8AEB910V provides enhanced specifications and AEC-Q200 qualification.
