Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE072K49L is determined by the following criteria:

Primary Matching Parameters:

Resistance value: 2.49 kOhms (exact match required)
Package format: 0805 (2012 Metric) (exact match required)
Composition: Thin Film (exact match required)
Operating temperature range: -55°C ~ 155°C (minimum requirement)

Allowable Variations:

Tolerance: ±1% or tighter (±0.5%, ±0.1%)
Power rating: 0.125W or higher (0.25W acceptable)
Temperature coefficient: ±50ppm/°C or better (±25ppm/°C acceptable)
Certifications: ROHS3 compliance required; AEC-Q200 automotive qualification is an upgrade feature

Substitute parts are grouped into three categories: Upgrade (tighter tolerance or better temperature coefficient), Direct (equivalent specifications from alternate manufacturer), and Upgrade with Enhanced Features (automotive qualification or anti-sulfur properties).

Engineering Selection Recommendations

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

For Standard Industrial Applications: RT0805BRD072K49L and RT0805DRD072K49L (YAGEO) provide tighter tolerance and improved temperature coefficient specifications while maintaining the same 0805 package footprint and power rating. These upgrades reduce circuit drift over temperature and improve overall circuit stability.

For Higher Power Dissipation Requirements: 5-2176092-1 (TE Connectivity) offers 0.25W power rating with ±0.1% tolerance and ±25ppm/°C temperature coefficient, suitable for applications requiring additional thermal margin.

For Automotive and Harsh Environment Applications: ERA-6AEB2491V (Panasonic) and RG2012P-2491-B-T5 / RG2012P-2491-D-T5 (Susumu) carry AEC-Q200 automotive qualification. The Susumu parts additionally feature anti-sulfur coating for enhanced reliability in corrosive environments. These are direct substitutes for applications requiring automotive-grade component certification.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD072K49L replace RT0805FRE072K49L in my circuit? A: Yes. RT0805BRD072K49L is a direct substitute with improved specifications: ±0.1% tolerance (versus ±1%) and ±25ppm/°C temperature coefficient (versus ±50ppm/°C). The tighter tolerance and lower temperature drift provide enhanced circuit performance with identical package and power rating.

Q: What is the difference between RT0805DRD072K49L and RT0805DRE072K49L? A: Both parts have ±0.5% tolerance and 0.125W power rating in 0805 package. The primary difference is temperature coefficient: RT0805DRD072K49L has ±25ppm/°C while RT0805DRE072K49L has ±50ppm/°C. RT0805DRD072K49L is preferred for temperature-sensitive applications.

Q: Can I use 5-2176092-1 (0.25W) instead of the original 0.125W part? A: Yes. The 0.25W rating is a higher power capability and is backward compatible. The part occupies the same 0805 footprint and can be used in any application designed for 0.125W or lower power dissipation. This substitution provides additional thermal margin.

Q: What does AEC-Q200 qualification mean? A: AEC-Q200 is an automotive electronics qualification standard. Parts carrying this certification (ERA-6AEB2491V, RG2012P-2491-B-T5, RG2012P-2491-D-T5) have undergone additional reliability testing and are approved for automotive applications. These parts are suitable for both automotive and industrial applications.

Q: Are all substitute parts available in the same tape and reel packaging? A: Yes. All listed substitute parts are supplied in Tape & Reel (TR) packaging, maintaining compatibility with standard pick-and-place assembly equipment and storage requirements.

Q: What is the anti-sulfur feature on Susumu RG2012P parts? A: Anti-sulfur coating protects the resistor from sulfur-containing contaminants in harsh industrial and marine environments. This feature extends component life in corrosive atmospheres without affecting electrical performance or package dimensions.
