Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE07243RL is determined by the following criteria:

Primary Substitution Parameters:

• Resistance value: 243 Ohms (exact match required)
• Package / Case: 0805 (2012 Metric) (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)
• Composition: Thin Film (preferred for consistency)
• RoHS compliance: ROHS3 Compliant (regulatory requirement)

Secondary Substitution Parameters:

• Tolerance: ±1% or better (tighter tolerance acceptable)
• Power rating: 0.125W or higher (higher rating acceptable)
• Temperature coefficient: ±50ppm/°C or better (lower coefficient acceptable)

Three substitute parts meet these criteria with varying performance enhancements.

Parameter Comparison

Engineering Selection Recommendations

RT0805BRD07243RL (YAGEO): Direct upgrade within the same manufacturer series. Maintains identical package and power rating while improving tolerance to ±0.1% and reducing temperature coefficient to ±25ppm/°C. Suitable for applications requiring enhanced precision without power or thermal modifications.

6-2176091-0 (TE Connectivity Passive Product): Cross-manufacturer substitute with identical tolerance and temperature coefficient performance. Provides increased power rating of 0.25W (1/4W), accommodating higher dissipation requirements within the same 0805 package footprint. Height specification increases marginally from 0.024" to 0.026" maximum seated height.

ERA-6AEB2430V (Panasonic Electronic Components): Automotive-grade substitute qualified to AEC-Q200 standard. Matches tolerance and temperature coefficient performance of other substitutes while maintaining 0.125W power rating. Appropriate for automotive and high-reliability applications requiring automotive component qualification.

All substitute parts maintain ROHS3 compliance, MSL Level 1 rating, and identical operating temperature range. Selection depends on application requirements for tolerance precision, power dissipation capacity, and industry qualification standards.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD07243RL replace RT0805FRE07243RL in any circuit? A: Yes. Both components share identical resistance, package, power rating, and operating temperature specifications. The improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C) make RT0805BRD07243RL a direct upgrade suitable for all applications using the original part.

Q: What is the advantage of using 6-2176091-0 over the original part? A: The 6-2176091-0 provides doubled power rating (0.25W vs 0.125W) within the same 0805 package, enabling use in circuits with higher power dissipation requirements. Tolerance and temperature coefficient are also improved. Physical height increases by 0.002" (0.05mm), which is negligible for most PCB layouts.

Q: Is ERA-6AEB2430V suitable for non-automotive applications? A: Yes. ERA-6AEB2430V meets all electrical and mechanical specifications for the original RT0805FRE07243RL. The AEC-Q200 automotive qualification is an additional feature that does not restrict use in standard industrial or consumer applications.

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 component's delivery format.

Q: What is the maximum height difference between substitute parts? A: RT0805FRE07243RL and RT0805BRD07243RL are both 0.024" (0.60mm) maximum seated height. The 6-2176091-0 is 0.026" (0.65mm) maximum seated height, a difference of 0.002" (0.05mm). ERA-6AEB2430V matches the original at 0.024" (0.60mm).
