Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0744K2L is determined by the following criteria:

Primary Matching Parameters:

• Resistance value: 44.2 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 requirement)
• RoHS compliance: ROHS3 Compliant (minimum requirement)

Secondary Allowable Variations:

• Tolerance: ±1% or tighter (±0.1% acceptable as upgrade)
• Power rating: Equal to or greater than 0.125W
• Temperature coefficient: Equal to or lower absolute value
• Moisture sensitivity: MSL 1 or better

Substitute parts are grouped into two categories: upgrade substitutes (improved tolerance and temperature coefficient) and direct substitutes (equivalent or enhanced power rating).

Parameter Comparison

Engineering Selection Recommendations

RT0805BRD0744K2L (YAGEO Upgrade Substitute) Select this part when improved tolerance and temperature stability are required within the same manufacturer ecosystem. The ±0.1% tolerance and ±25ppm/°C temperature coefficient provide enhanced precision over the main part. ROHS3 compliance and MSL 1 rating maintain regulatory and environmental requirements. Identical package and power rating ensure direct PCB compatibility.

6-2176093-2 (TE Connectivity Direct Substitute) Select this part when increased power dissipation capability is needed. The 0.25W (1/4W) rating provides margin for thermal stress while maintaining the 0805 package footprint. TE Connectivity manufacturing and ±0.1% tolerance deliver equivalent or superior performance. Height specification (0.026" maximum) is marginally higher than the main part; verify PCB clearance in space-constrained applications. ROHS3 compliance confirmed; REACH status is vendor undefined.

ERA-6AEB4422V (Panasonic Automotive Upgrade Substitute) Select this part for applications requiring automotive-grade reliability. AEC-Q200 qualification provides enhanced qualification and traceability for automotive supply chains. Panasonic manufacturing with ±0.1% tolerance and ±25ppm/°C temperature coefficient exceeds main part specifications. ROHS3 and REACH compliance confirmed. Identical package and power rating ensure direct PCB compatibility.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD0744K2L replace RT0805FRE0744K2L in any application? A: Yes. RT0805BRD0744K2L is a direct upgrade substitute. It maintains identical resistance, package, power rating, and operating temperature range. The improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C) are compatible with all applications designed for the main part.

Q: What is the primary difference between 6-2176093-2 and the main part? A: The primary difference is power rating: 6-2176093-2 is rated for 0.25W (1/4W) versus 0.125W (1/8W) for RT0805FRE0744K2L. Both share identical resistance, tolerance, package, and operating temperature. The higher power rating provides thermal margin. Maximum seated height is 0.026" (6-2176093-2) versus 0.024" (main part); verify clearance in height-restricted designs.

Q: Is ERA-6AEB4422V suitable for non-automotive applications? A: Yes. ERA-6AEB4422V meets or exceeds all specifications of the main part and is suitable for any application. AEC-Q200 qualification is an additional feature that does not restrict use in non-automotive circuits. The ±0.1% tolerance and ±25ppm/°C temperature coefficient provide enhanced performance.

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 main part format. This ensures compatibility with automated assembly processes.

Q: Can I use 6-2176093-2 in a design with strict height constraints? A: Verify PCB clearance. The maximum seated height of 6-2176093-2 is 0.026" (0.65mm) compared to 0.024" (0.60mm) for the main part. The 0.05mm difference is minimal but must be confirmed in space-constrained applications.

Q: What compliance certifications apply to all substitute parts? A: All substitute parts are ROHS3 compliant and carry MSL 1 (unlimited moisture sensitivity) rating. ERA-6AEB4422V additionally holds AEC-Q200 automotive qualification. REACH compliance is confirmed for RT0805BRD0744K2L and ERA-6AEB4422V; 6-2176093-2 REACH status is vendor undefined.
