Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE072K43L is determined by the following criteria:

Mandatory Compatibility Parameters:

• Resistance value: 2.43 kOhms (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Operating temperature range: -55°C to 155°C minimum (equal or wider range acceptable)
• RoHS compliance: ROHS3 Compliant (equal or higher standard acceptable)

Allowable Upgrade Parameters:

• Tolerance: ±1% or better (±0.1% acceptable as upgrade)
• Power rating: 0.125W or higher (0.25W acceptable as upgrade)
• Temperature coefficient: ±50ppm/°C or better (±25ppm/°C acceptable as upgrade)
• Automotive certification: AEC-Q200 acceptable for applications requiring automotive-grade components

All substitute parts listed maintain identical resistance, package, and composition specifications while offering improvements in one or more electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

RT0805BRE072K43L (YAGEO): Select this part when improved tolerance (±0.1%) is required while maintaining identical power rating and thermal characteristics. Both parts are manufactured by YAGEO and share the same series designation (RT), ensuring consistent performance and supply chain compatibility.

5-2176092-0 (TE Connectivity): Select this part when applications require higher power dissipation capability (0.25W vs. 0.125W) or improved temperature coefficient stability (±25ppm/°C vs. ±50ppm/°C). The increased height (0.026" vs. 0.024") must be verified against PCB layout constraints. This part is suitable for designs with thermal margin requirements or precision analog circuits.

ERA-6AEB2431V (Panasonic): Select this part for automotive applications requiring AEC-Q200 certification. This part combines tolerance upgrade (±0.1%), improved temperature coefficient (±25ppm/°C), and automotive-grade qualification. Use this part when designs must meet automotive reliability and qualification standards.

All substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRE072K43L replace RT0805FRE072K43L in any application?

A: Yes. RT0805BRE072K43L is a direct substitute with improved tolerance (±0.1% vs. ±1%). All other electrical and mechanical parameters are identical. No design changes are required.

Q: What is the primary difference between 5-2176092-0 and the original part?

A: The 5-2176092-0 offers two upgrades: higher power rating (0.25W vs. 0.125W) and better temperature coefficient (±25ppm/°C vs. ±50ppm/°C). Physical dimensions are nearly identical, with a maximum height increase of 0.002" (0.05mm). Verify PCB clearance before substitution.

Q: When should ERA-6AEB2431V be used instead of other substitutes?

A: ERA-6AEB2431V is specified for automotive applications requiring AEC-Q200 certification. Use this part when designs must comply with automotive reliability standards or when sourcing from automotive-qualified suppliers is mandatory.

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

A: Yes. All parts listed are supplied in Tape & Reel (TR) packaging in 0805 (2012 Metric) case format, ensuring compatibility with standard pick-and-place assembly equipment.

Q: Can tolerance be downgraded from ±0.1% to ±1% if cost reduction is needed?

A: No. The original RT0805FRE072K43L at ±1% tolerance is the baseline specification. Substitute parts with ±0.1% tolerance represent upgrades only and are not interchangeable in reverse.

Q: What is the impact of temperature coefficient differences on circuit performance?

A: Temperature coefficient affects resistance stability across the operating temperature range. The original part (±50ppm/°C) exhibits greater resistance drift than substitutes with ±25ppm/°C. For precision analog circuits or wide temperature applications, select parts with lower temperature coefficients.
