Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206CRE0739RL is determined by the following mandatory parameters:

• Resistance value must equal 39 Ohms
• Package / Case must be 1206 (3216 Metric)
• Power rating must be 0.25W (1/4W) or higher
• Composition must be Thin Film
• Operating temperature range must encompass -55°C ~ 155°C
• RoHS3 compliance must be maintained

The RT1206BRD0739RL qualifies as a direct substitute. While this part features improved tolerance (±0.1% versus ±0.25%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), all mandatory electrical and mechanical parameters remain equivalent. The enhanced specifications represent a performance upgrade without altering form factor or fundamental electrical characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both RT1206CRE0739RL and RT1206BRD0739RL are Active products manufactured by YAGEO with full RoHS3 compliance and REACH Unaffected status. Selection between these parts should be based on application-specific tolerance and temperature stability requirements. The RT1206BRD0739RL provides tighter tolerance control (±0.1%) and improved temperature coefficient performance (±25ppm/°C), making it suitable for precision analog circuits and temperature-sensitive applications. The RT1206CRE0739RL remains appropriate for general-purpose applications where ±0.25% tolerance meets design specifications. Both components are suitable for direct PCB assembly using standard SMD reflow processes and maintain identical mechanical compatibility.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD0739RL replace RT1206CRE0739RL in existing designs?

A: Yes. Both parts share identical resistance values, power ratings, package dimensions, and operating temperature ranges. The RT1206BRD0739RL features improved tolerance and temperature coefficient specifications, making it a direct electrical and mechanical substitute.

Q: Are there physical footprint differences between these parts?

A: No. Both components use the 1206 (3216 Metric) package with identical dimensions: 0.122" L x 0.063" W (3.10mm x 1.60mm) and maximum seated height of 0.026" (0.65mm). PCB layouts require no modification.

Q: What is the significance of tolerance differences?

A: The RT1206CRE0739RL specifies ±0.25% tolerance, while RT1206BRD0739RL specifies ±0.1%. Tighter tolerance reduces resistance value variation across production batches. Applications requiring precise resistance values benefit from the improved specification.

Q: Do these parts have different moisture sensitivity requirements?

A: No. Both components are rated MSL 1 (Unlimited), indicating no moisture sensitivity limitations during storage or handling.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both RT1206CRE0739RL and RT1206BRD0739RL are ROHS3 Compliant and REACH Unaffected, meeting current environmental and regulatory requirements.
