Substitute Part Grouping Explanation

Substitute parts for the RT0805FRE0766R5L are qualified based on the following criteria:

Primary Substitution Criteria:

• Identical resistance value: 66.5 Ohms
• Identical package format: 0805 (2012 Metric)
• Identical composition: Thin Film
• Identical operating temperature range: -55°C ~ 155°C
• Identical MSL rating: 1 (Unlimited)
• ROHS3 compliance maintained

Tolerance and Power Rating Variations: Substitute parts may feature improved tolerance (±0.1% versus ±1%) and/or increased power rating (0.25W versus 0.125W). These represent upgrades that maintain full backward compatibility while providing enhanced performance margins.

Parameter Comparison

Engineering Selection Recommendations

RT0805BRD0766R5L (YAGEO Upgrade): This part provides direct substitution with improved tolerance specification (±0.1% versus ±1%) and reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C). Identical power rating and package dimensions ensure seamless PCB integration. Maintains ROHS3 compliance and unlimited MSL rating. Suitable for applications requiring tighter tolerance control without power rating modifications.

2176091-7 (TE Connectivity Alternative): This part maintains identical resistance, tolerance, and temperature coefficient to the RT0805BRD0766L upgrade while providing increased power dissipation capability (0.25W versus 0.125W). Maximum seated height increases by 0.002" (0.05mm). ROHS3 compliance confirmed; REACH status listed as Vendor Undefined. Suitable for applications requiring enhanced thermal performance or higher power margins within the 0805 package footprint.

All substitute parts maintain Active product status and full regulatory compliance for direct component selection in equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD0766R5L replace RT0805FRE0766R5L in existing designs?

A: Yes. Both parts share identical resistance value, package format, operating temperature range, and physical dimensions. The RT0805BRD0766R5L provides improved tolerance (±0.1% versus ±1%) and lower temperature coefficient, making it a direct upgrade with no PCB layout modifications required.

Q: What is the primary difference between RT0805BRD0766R5L and 2176091-7?

A: The primary difference is power rating. RT0805BRD0766R5L is rated at 0.125W (1/8W), while 2176091-7 is rated at 0.25W (1/4W). Both maintain identical resistance, tolerance, and temperature coefficient. The 2176091-7 has a maximum seated height of 0.026" (0.65mm) versus 0.024" (0.60mm) for the YAGEO parts. Component selection depends on thermal dissipation requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. RT0805FRE0766R5L, RT0805BRD0766R5L, and 2176091-7 are all ROHS3 compliant. MSL rating is 1 (Unlimited) for all parts, indicating no moisture sensitivity restrictions.

Q: Does the 0.002" height difference between YAGEO and TE Connectivity parts affect PCB assembly?

A: The height difference (0.024" versus 0.026" maximum seated height) is within standard PCB assembly tolerances for 0805 components. No design modifications are required. Verify with assembly process specifications if clearance constraints exist in the application.

Q: Can 2176091-7 be used in place of RT0805FRE0766R5L?

A: Yes. The 2176091-7 provides identical electrical performance with enhanced power rating (0.25W versus 0.125W). The slight height increase and TE Connectivity manufacturer designation are the only physical and sourcing differences. Verify REACH compliance requirements for your application, as TE Connectivity lists REACH status as Vendor Undefined.
