Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE074K42L is determined by the following criteria:

Primary Matching Parameters:

• Resistance value: 4.42 kOhms (exact match required)
• Package form factor: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)
• RoHS compliance: ROHS3 Compliant (minimum requirement)

Secondary Allowable Variations:

• 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)

Three substitute parts meet these criteria: RT0805BRD074K42L (YAGEO), 7-2176092-4 (TE Connectivity), and ERA-6AEB4421V (Panasonic).

Parameter Comparison

Engineering Selection Recommendations

RT0805BRD074K42L (YAGEO): Direct upgrade from the main part within the same manufacturer. Offers improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C) while maintaining identical power rating and package specifications. ROHS3 compliant with unlimited MSL rating. Suitable for applications requiring tighter tolerance control.

7-2176092-4 (TE Connectivity): Provides enhanced power rating (0.25W vs 0.125W) with ±0.1% tolerance and ±25ppm/°C temperature coefficient. Maintains 0805 package form factor and full operating temperature range. ROHS3 compliant. Appropriate for designs requiring higher power dissipation margin or thermal headroom.

ERA-6AEB4421V (Panasonic): Automotive-grade AEC-Q200 certified thin film resistor with ±0.1% tolerance and ±25ppm/°C temperature coefficient. Identical power rating and package to the main part. ROHS3 compliant with unlimited MSL. Required for automotive applications or systems demanding automotive-grade component qualification.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD074K42L replace RT0805FRE074K42L in any application? A: Yes. RT0805BRD074K42L is a direct upgrade offering superior tolerance and temperature coefficient specifications while maintaining identical package, power rating, and operating temperature range. No circuit redesign is required.

Q: What is the primary difference between 7-2176092-4 and the main part? A: The 7-2176092-4 features double the power rating (0.25W vs 0.125W) and improved tolerance (±0.1% vs ±1%). All other electrical and mechanical parameters remain compatible. Use this part when additional thermal margin is required.

Q: When should ERA-6AEB4421V be selected? A: ERA-6AEB4421V is the appropriate choice for automotive applications or designs requiring AEC-Q200 certification. It provides equivalent electrical performance to RT0805BRD074K42L with automotive-grade qualification.

Q: Are all substitute parts available in the same packaging format? A: Yes. All listed substitutes are supplied in Tape & Reel (TR) packaging and use the 0805 (2012 Metric) form factor, ensuring compatibility with standard SMD assembly processes.

Q: Can these parts be used interchangeably on the same PCB? A: Yes. All parts share identical 0805 package dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and footprint requirements. Mechanical and electrical interchangeability is confirmed for PCB assembly.

Q: What is the tolerance difference impact? A: The main part specifies ±1% tolerance, while all substitutes offer ±0.1% tolerance. This represents a 10-fold improvement in resistance accuracy. Applications with strict impedance or biasing requirements benefit from the tighter tolerance.

Q: Are moisture sensitivity levels identical across all parts? A: Yes. All parts carry MSL rating 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
