Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0739R2L is determined by the following critical parameters:

• Resistance Value: Must be 39.2 Ohms (exact match required)
• Package Type: Must be 0805 (2012 Metric) for mechanical and electrical compatibility
• Composition: Thin film construction ensures performance characteristics suitable for precision applications
• Operating Temperature Range: Must support -55°C to 155°C minimum
• Compliance: RoHS3 compliance and REACH unaffected status required for regulatory alignment

The substitute part 8-1625868-4 (TE Connectivity Passive Product) meets all mandatory substitution criteria. Enhanced specifications in tolerance (±0.1% vs ±1%) and power rating (0.25W vs 0.125W) provide performance headroom without compromising compatibility.

Parameter Comparison

Engineering Selection Recommendations

The RT0805FRE0739R2L and 8-1625868-4 are both active products with full RoHS3 compliance and REACH unaffected status, ensuring regulatory alignment for current and future applications. Both components maintain identical operating temperature ranges and moisture sensitivity classifications, supporting deployment in standard industrial and commercial environments.

The TE Connectivity substitute (8-1625868-4) provides enhanced performance margins across tolerance, power dissipation, and temperature coefficient specifications while maintaining identical mechanical and electrical package compatibility. Selection between these parts should be based on application-specific requirements for tolerance precision and thermal headroom, as well as inventory availability and supply chain considerations.

Frequently Asked Questions (FAQ)

Q: Can 8-1625868-4 be used as a direct replacement for RT0805FRE0739R2L?

A: Yes. Both components share identical resistance values (39.2 Ohms), package type (0805), composition (thin film), and operating temperature range (-55°C to 155°C). The substitute meets or exceeds all critical electrical and mechanical parameters.

Q: What are the key differences between these parts?

A: The TE Connectivity part offers tighter tolerance (±0.1% vs ±1%), higher power rating (0.25W vs 0.125W), and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C). These represent performance enhancements rather than deviations from the original specification.

Q: Are there any physical compatibility concerns?

A: No. Both components use identical 0805 (2012 Metric) packaging with matching footprint dimensions (0.079" L x 0.049" W). PCB layout and assembly processes require no modification.

Q: Do both parts meet the same compliance standards?

A: Yes. Both are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronics manufacturing and distribution.

Q: Which part should be selected for new designs?

A: Selection depends on application requirements. If tolerance precision or thermal dissipation headroom is critical, the TE Connectivity part (8-1625868-4) provides enhanced performance. For applications where the original specification is sufficient, either part is suitable based on availability and cost considerations.
