Equivalent & Substitute Parts for RT0805FRE0773K2L

Part Overview

The RT0805FRE0773K2L is a 73.2 kOhms ±1% thin film chip resistor in 0805 (2012 Metric) package manufactured by YAGEO. This surface mount device is rated for 0.125W (1/8W) power dissipation with an operating temperature range of -55°C to 155°C. The part is currently active in production and ROHS3 compliant. Substitute parts are identified when equivalent electrical performance and mechanical compatibility can be maintained across the same package footprint and resistance value.

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0773K2L is determined by the following criteria:

Primary Compatibility Requirements:

• Resistance value: 73.2 kOhms (exact match required)
• Package: 0805 (2012 Metric) footprint
• Composition: Thin film construction
• Termination count: 2 terminations
• Moisture sensitivity: MSL 1 or better
• Operating temperature range: -55°C to 155°C minimum

Allowable Parameter Variations:

• Tolerance: ±1% or tighter (±0.1% acceptable)
• Power rating: Equal to or greater than 0.125W
• Temperature coefficient: ±50ppm/°C or better
• RoHS and REACH compliance status

Three substitute parts meet these criteria and are grouped as follows:

Upgrade Category (Tighter Tolerance): RT0805BRD0773K2L and ERA-6AEB7322V both offer ±0.1% tolerance with improved temperature coefficient (±25ppm/°C).

Alternative Category (Higher Power Rating): 8-2176093-2 provides 0.25W (1/4W) power rating with ±0.1% tolerance, suitable for applications requiring additional thermal margin.

Parameter Comparison

Engineering Selection Recommendations

RT0805BRD0773K2L (YAGEO): Direct upgrade within the same manufacturer series. Maintains ROHS3 compliance and REACH unaffected status. Tighter tolerance (±0.1%) and improved temperature coefficient (±25ppm/°C) provide enhanced precision. Identical package dimensions and power rating. Recommended for applications requiring improved accuracy without design modification.

ERA-6AEB7322V (Panasonic): Upgrade option with automotive AEC-Q200 qualification. Maintains ROHS3 compliance and REACH unaffected status. Tighter tolerance and improved temperature coefficient match RT0805BRD0773K2L specifications. Suitable for automotive and high-reliability applications. Identical package dimensions and power rating.

8-2176093-2 (TE Connectivity): Alternative with increased power rating (0.25W vs. 0.125W). Provides thermal margin for applications with higher dissipation requirements. Height dimension increases to 0.65mm maximum. RoHS non-compliant status and vendor-undefined REACH status require compliance verification. Use only when higher power rating is functionally required and compliance restrictions do not apply.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD0773K2L replace RT0805FRE0773K2L in all applications?

A: Yes, within the same electrical and thermal operating conditions. RT0805BRD0773K2L provides tighter tolerance (±0.1% vs. ±1%) and lower temperature coefficient (±25ppm/°C vs. ±50ppm/°C), making it suitable for precision applications. No PCB layout changes are required due to identical 0805 package dimensions.

Q: What is the primary difference between the three substitute parts?

A: RT0805BRD0773K2L and ERA-6AEB7322V both offer ±0.1% tolerance and ±25ppm/°C temperature coefficient at 0.125W power rating. ERA-6AEB7322V adds AEC-Q200 automotive qualification. The 8-2176093-2 provides doubled power rating (0.25W) but increases seated height to 0.65mm and lacks RoHS3 compliance.

Q: Is the 0.65mm height of 8-2176093-2 a concern for PCB assembly?

A: The 0.05mm height increase may affect PCB clearance in space-constrained designs. Verify clearance to adjacent components and solder reflow profiles. For standard applications with 0.60mm height tolerance, this difference is typically acceptable.

Q: Which substitute is recommended for automotive applications?

A: ERA-6AEB7322V is qualified to AEC-Q200 automotive standards and maintains ROHS3 compliance and REACH unaffected status. It provides the same electrical performance as RT0805BRD0773K2L with automotive-grade reliability.

Q: Can 8-2176093-2 be used in RoHS-restricted applications?

A: No. The 8-2176093-2 is RoHS non-compliant and has vendor-undefined REACH status. Use only in applications where RoHS compliance is not required. For RoHS-compliant designs, select RT0805BRD0773K2L or ERA-6AEB7322V.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All substitute parts listed are supplied in Tape & Reel (TR) packaging, maintaining compatibility with automated assembly processes.
