RT1206DRD07649RL Equivalent & Substitute Parts

Part Overview

The RT1206DRD07649RL is a 649 Ohm ±0.5% thin film chip resistor manufactured by YAGEO in 1206 (3216 Metric) package format. This component is rated for 0.25W (1/4W) power dissipation with an operating temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1).

Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the same resistance value, tolerance class, power rating, and package specification.

Key Parameters

Substitute Part Grouping Explanation

The ERA-8AEB6490V qualifies as a direct substitute based on the following alignment of critical parameters:

• Identical resistance value: 649 Ohms
• Identical package format: 1206 (3216 Metric)
• Identical power rating: 0.25W (1/4W)
• Identical composition: Thin Film
• Identical temperature coefficient: ±25ppm/°C
• Identical operating temperature range: -55°C to 155°C
• Identical RoHS and MSL compliance status

The ERA-8AEB6490V provides improved tolerance specification (±0.1% versus ±0.5%), which represents a performance upgrade while maintaining full mechanical and electrical compatibility. The addition of AEC-Q200 automotive qualification does not restrict general-purpose applications.

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206DRD07649RL and ERA-8AEB6490V maintain Active product status and full compliance with ROHS3 and REACH requirements. The ERA-8AEB6490V carries AEC-Q200 automotive qualification, which certifies reliability for automotive applications but does not restrict use in general industrial or consumer electronics.

Selection between these parts should be based on availability, lead time, and cost considerations. The ERA-8AEB6490V's tighter tolerance specification (±0.1%) provides improved accuracy for precision circuit applications where tolerance stack-up is a design constraint.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB6490V replace RT1206DRD07649RL in existing designs?

A: Yes. Both parts share identical resistance, power rating, package format, and operating temperature range. The ERA-8AEB6490V is mechanically and electrically compatible with no design modifications required.

Q: What is the significance of the ±0.1% tolerance on the ERA-8AEB6490V?

A: The tighter tolerance reduces resistance variation from ±0.5% to ±0.1%, resulting in more precise circuit performance. This is beneficial in applications where component tolerance contributes significantly to overall circuit accuracy.

Q: Does AEC-Q200 qualification on the ERA-8AEB6490V restrict its use?

A: No. AEC-Q200 is an automotive reliability standard. Parts meeting this qualification are suitable for all applications, including general industrial and consumer use.

Q: Are the physical dimensions identical between these parts?

A: Both parts use the 1206 (3216 Metric) package. Minor dimensional variations exist (RT1206DRD07649RL: 3.10mm × 1.60mm; ERA-8AEB6490V: 3.20mm × 1.60mm length and height), which remain within standard PCB footprint tolerances and do not affect interchangeability.

Q: What compliance certifications apply to both parts?

A: Both parts are ROHS3 compliant, REACH unaffected, and carry MSL 1 (unlimited moisture sensitivity) rating, indicating no special moisture handling requirements during storage or assembly.
