Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0724R3L is determined by the following critical parameters:

• Resistance value: 24.3 Ohms (exact match required)
• Package format: 0805 (2012 Metric) (physical and electrical compatibility)
• Composition: Thin Film (performance characteristics)
• Operating temperature range: -55°C to 155°C (minimum requirement)
• RoHS3 compliance and MSL Level 1 rating (regulatory and environmental requirements)

The substitute part 6-1625868-4 (TE Connectivity Passive Product) meets all critical substitution criteria. This part exceeds the original specification in tolerance (±0.1% vs. ±1%) and power rating (0.25W vs. 0.125W), while maintaining identical resistance value, package format, and regulatory compliance. The improved temperature coefficient (±25ppm/°C vs. ±50ppm/°C) provides enhanced stability across the operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The RT0805FRE0724R3L and 6-1625868-4 are functionally interchangeable for applications requiring a 24.3 Ohm thin film resistor in the 0805 package format. Both parts maintain Active product status and full RoHS3 compliance with MSL Level 1 rating, ensuring regulatory and environmental compatibility.

Selection between these parts should be based on application requirements:

• Use RT0805FRE0724R3L when the original specification tolerance of ±1% and power rating of 0.125W are sufficient for the circuit design.
• Use 6-1625868-4 when improved tolerance performance (±0.1%), higher power dissipation capability (0.25W), or enhanced temperature stability (±25ppm/°C) are beneficial to circuit performance or reliability margins.

Both parts are suitable for applications operating across the -55°C to 155°C temperature range and are compatible with standard PCB assembly processes for 0805 components.

Frequently Asked Questions (FAQ)

Q: Can 6-1625868-4 be used as a direct replacement for RT0805FRE0724R3L?

A: Yes. Both parts share identical resistance value (24.3 Ohms), package format (0805), composition (thin film), and operating temperature range (-55°C to 155°C). The substitute part meets or exceeds all critical electrical and mechanical specifications.

Q: What are the key differences between these parts?

A: The primary differences are tolerance (±0.1% vs. ±1%), power rating (0.25W vs. 0.125W), and temperature coefficient (±25ppm/°C vs. ±50ppm/°C). The substitute part provides tighter tolerance and higher power capability, making it suitable for applications requiring enhanced performance margins.

Q: Are there any PCB layout or assembly considerations when switching between these parts?

A: Both parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W). The maximum seated height differs slightly (0.026" vs. 0.024"), which is negligible for standard PCB assembly. No layout modifications are required.

Q: Do both parts meet the same regulatory and compliance standards?

A: Yes. Both RT0805FRE0724R3L and 6-1625868-4 are RoHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity rating. Both are classified under ECCN EAR99 and HTSUS 8533.21.0030.

Q: Which part should be selected for high-reliability applications?

A: The 6-1625868-4 is suitable for high-reliability applications due to its superior tolerance specification (±0.1%), lower temperature coefficient (±25ppm/°C), and higher power rating (0.25W), which provide greater design margin and stability across the operating temperature range.
