Key Parameters

Substitute Part Grouping Explanation

Substitution of the RT0805FRE073K09L is determined by the following critical parameters: resistance value (3.09 kOhms), package type (0805), composition (thin film), and operating temperature range (-55°C to 155°C). All substitute parts maintain these core specifications.

Substitute parts are grouped into two categories based on tolerance and power rating specifications:

Tolerance Upgrade Substitutes (±0.1%): RT0805BRD073K09L (YAGEO), ERA-6AEB3091V (Panasonic), and RG2012P-3091-B-T5 (Susumu) offer improved tolerance of ±0.1% compared to the original ±1%, with reduced temperature coefficient of ±25ppm/°C versus ±50ppm/°C.

Power Rating Upgrade Substitute (0.25W): 5-2176092-9 (TE Connectivity) maintains ±0.1% tolerance but increases power rating to 0.25W (1/4W), suitable for applications requiring higher power dissipation while preserving the 0805 package footprint.

Parameter Comparison

Engineering Selection Recommendations

For Standard Applications: RT0805BRD073K09L provides direct substitution with improved tolerance (±0.1%) and reduced temperature coefficient (±25ppm/°C) while maintaining identical power rating and package specifications. This part is ROHS3 compliant and carries unlimited MSL rating.

For Automotive Applications: ERA-6AEB3091V and RG2012P-3091-B-T5 are both AEC-Q200 certified, meeting automotive-grade reliability requirements. ERA-6AEB3091V is manufactured by Panasonic with standard thin film construction. RG2012P-3091-B-T5 by Susumu includes anti-sulfur features in addition to AEC-Q200 certification, providing enhanced environmental protection.

For Higher Power Dissipation: 5-2176092-9 from TE Connectivity increases power rating to 0.25W (1/4W) while maintaining ±0.1% tolerance and identical package footprint. This option is suitable for applications requiring increased thermal headroom within the 0805 form factor.

All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard PCB assembly processes and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD073K09L be used as a direct replacement for RT0805FRE073K09L?

A: Yes. Both parts share identical resistance value (3.09 kOhms), package type (0805), power rating (0.125W), and operating temperature range (-55°C to 155°C). RT0805BRD073K09L offers improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it a superior substitute for precision applications.

Q: What is the difference between the 0.125W and 0.25W power-rated versions?

A: Power rating indicates maximum continuous power dissipation capability. The 0.125W version (RT0805FRE073K09L, RT0805BRD073K09L, ERA-6AEB3091V, RG2012P-3091-B-T5) is suitable for standard signal-level applications. The 0.25W version (5-2176092-9) accommodates higher current or voltage stress, providing additional thermal margin. Both maintain identical 0805 package dimensions.

Q: Are automotive-grade parts (AEC-Q200) required for this application?

A: AEC-Q200 certification is required only for automotive applications. ERA-6AEB3091V and RG2012P-3091-B-T5 carry this certification. For non-automotive applications, standard industrial-grade substitutes (RT0805BRD073K09L or 5-2176092-9) are acceptable.

Q: Does the anti-sulfur feature of RG2012P-3091-B-T5 provide additional benefits?

A: Anti-sulfur construction protects against sulfur-induced corrosion in high-sulfur environments. This feature is beneficial for applications exposed to industrial atmospheres or specific geographic locations with elevated atmospheric sulfur levels. For standard indoor or controlled environments, this feature provides no functional advantage.

Q: Are all substitute parts available in the same packaging format?

A: Yes. All substitute parts are supplied in Tape & Reel (TR) packaging, matching the original RT0805FRE073K09L format. Package dimensions and termination count (2) are identical across all parts, ensuring compatibility with standard pick-and-place assembly equipment.

Q: What is the significance of the ±50ppm/°C versus ±25ppm/°C temperature coefficient difference?

A: Temperature coefficient indicates resistance value drift per degree Celsius change. The original part (±50ppm/°C) exhibits twice the temperature-induced variation compared to substitute parts (±25ppm/°C). For precision analog circuits or wide temperature range applications, the lower temperature coefficient of substitute parts provides improved stability and accuracy.
