Substitute Part Grouping Explanation

Substitution eligibility for the RT0805CRE0739R2L is determined by the following criteria:

• Identical resistance value: 39.2 Ohms
• Identical package format: 0805 (2012 Metric)
• Identical composition: Thin Film
• Identical operating temperature range: -55°C to 155°C
• Identical termination count: 2
• Identical RoHS3 compliance status
• Identical MSL rating: 1 (Unlimited)

The substitute part 8-1625868-4 (TE Connectivity Passive Product) meets all mandatory substitution criteria. This part demonstrates improved electrical characteristics in tolerance (±0.1% versus ±0.25%) and temperature coefficient (±25ppm/°C versus ±50ppm/°C), with increased power rating (0.25W versus 0.125W) and identical physical dimensions within the 0805 package specification.

Parameter Comparison

Engineering Selection Recommendations

Both the RT0805CRE0739R2L and 8-1625868-4 maintain Active product status with full RoHS3 compliance and REACH unaffected designation. Selection between these parts is based on application-specific requirements:

The RT0805CRE0739R2L is suitable for applications where the specified 0.125W power rating and ±0.25% tolerance meet design constraints.

The 8-1625868-4 provides enhanced performance characteristics with improved tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C), making it applicable in precision circuits requiring tighter resistance stability. The increased power rating (0.25W) accommodates higher dissipation environments. Physical compatibility is maintained with identical package dimensions and termination configuration.

Both parts satisfy identical compliance requirements and environmental ratings, ensuring regulatory and reliability equivalence.

Frequently Asked Questions (FAQ)

Q: Can 8-1625868-4 directly replace RT0805CRE0739R2L in existing designs?

A: Yes. Both parts share identical resistance value (39.2 Ohms), package format (0805), operating temperature range (-55°C to 155°C), and compliance certifications (RoHS3, MSL 1). Physical dimensions are equivalent within specification tolerances.

Q: What are the key differences between these parts?

A: The 8-1625868-4 offers improved tolerance (±0.1% versus ±0.25%), lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), and higher power rating (0.25W versus 0.125W). The seated height differs by 0.002" (0.05mm), remaining within 0805 package specifications.

Q: Are there any height clearance concerns?

A: The 8-1625868-4 has a maximum seated height of 0.026" (0.65mm) compared to 0.024" (0.60mm) for the RT0805CRE0739R2L. This 0.002" difference is negligible for standard PCB layouts and does not affect 0805 package compatibility.

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

A: Yes. Both parts are RoHS3 compliant, REACH unaffected, and rated MSL 1 (Unlimited). Operating temperature ranges are identical at -55°C to 155°C.

Q: Which part should be selected for precision applications?

A: The 8-1625868-4 is suitable for precision applications due to its tighter tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C), providing enhanced resistance stability across temperature variations.
