Substitute Part Grouping Explanation

Substitute parts for the RE0805FRE0739K2L are qualified based on the following criteria:

• Resistance Value: Exact match at 39.2 kOhms
• Package Form Factor: 0805 (2012 Metric) package required for mechanical and electrical compatibility
• Composition: Thick film construction maintained
• Temperature Coefficient: ±50ppm/°C matching the original specification
• Operating Temperature Range: -55°C ~ 155°C maintained
• RoHS Compliance: ROHS3 Compliant status required
• Moisture Sensitivity: MSL 1 (Unlimited) maintained

Substitute parts may differ in tolerance specification and power rating, provided these parameters remain within acceptable ranges for the application. The identified substitutes are manufactured by Panasonic Electronic Components under the ERJ-PB6 series.

Parameter Comparison

Engineering Selection Recommendations

Both ERJ-PB6B3922V and ERJ-PB6D3922V are active production parts from Panasonic Electronic Components and maintain full ROHS3 compliance and MSL 1 rating. The ERJ-PB6 series incorporates automotive AEC-Q200 qualification and pulse withstanding characteristics, providing enhanced reliability margins compared to the original RE0805FRE0739K2L.

The ERJ-PB6B3922V offers tighter tolerance at ±0.1%, while the ERJ-PB6D3922V provides ±0.5% tolerance. Both substitute parts feature increased power rating at 0.25W (1/4W) versus the original 0.125W (1/8W), allowing operation at higher dissipation levels within the same package footprint. Height difference of 0.004" (0.10mm) maximum between original and substitutes must be evaluated for applications with strict height constraints.

Frequently Asked Questions (FAQ)

Q: Can ERJ-PB6B3922V and ERJ-PB6D3922V be used interchangeably with RE0805FRE0739K2L?

A: Both Panasonic parts are mechanically and electrically compatible substitutes. The 0805 package form factor, resistance value, temperature coefficient, and operating temperature range are identical. Tolerance differences (±0.1% and ±0.5% versus ±1%) and increased power rating (0.25W versus 0.125W) represent improvements over the original specification.

Q: What is the significance of the height difference between the original and substitute parts?

A: The original RE0805FRE0739K2L has a maximum seated height of 0.024" (0.60mm), while both Panasonic substitutes measure 0.028" (0.70mm) maximum. This 0.004" (0.10mm) difference is within standard PCB assembly tolerances but must be verified for applications with height-critical constraints, such as confined spaces or specific mechanical assemblies.

Q: Are the Panasonic ERJ-PB6 series parts suitable for automotive applications?

A: Both ERJ-PB6B3922V and ERJ-PB6D3922V carry AEC-Q200 automotive qualification and pulse withstanding features. The original RE0805FRE0739K2L does not specify automotive qualification. Selection of Panasonic substitutes provides automotive-grade reliability for applications requiring this certification.

Q: How do tolerance specifications affect component selection?

A: The original RE0805FRE0739K2L specifies ±1% tolerance. ERJ-PB6B3922V offers ±0.1% tolerance, and ERJ-PB6D3922V offers ±0.5% tolerance. Tighter tolerance parts reduce resistance value variation across production batches. Selection depends on circuit requirements for precision; applications tolerating ±1% variation can use either substitute without performance impact.

Q: What does ROHS3 compliance and MSL 1 rating indicate?

A: ROHS3 compliance confirms the component meets Restriction of Hazardous Substances directive requirements, restricting lead and other hazardous materials. MSL 1 (Unlimited) indicates the component has unlimited shelf life and requires no special moisture control during storage or handling, simplifying supply chain management.
