Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206CRE0740R2L is determined by the following critical parameters:

• Resistance value must equal 40.2 Ohms
• Package format must be 1206 (3216 Metric)
• Power rating must be 0.25W minimum
• Composition must be thin film
• Operating temperature range must encompass -55°C to 155°C
• RoHS3 compliance required
• MSL rating must be 1 or equivalent

The RP73D2B40R2BTDF from TE Connectivity Passive Product qualifies as a direct substitute. This part maintains identical resistance, package, power rating, and temperature specifications while offering improved tolerance (±0.1% versus ±0.25%) and superior temperature coefficient (±15ppm/°C versus ±50ppm/°C). Both parts share equivalent mechanical dimensions and termination configuration.

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206CRE0740R2L and RP73D2B40R2BTDF maintain Active product status with full RoHS3 compliance and REACH unaffected designation. Selection between these parts should be based on application-specific tolerance and stability requirements. The RP73D2B40R2BTDF offers tighter tolerance and lower temperature coefficient, making it suitable for precision analog circuits and temperature-sensitive applications. The RT1206CRE0740R2L remains appropriate for general-purpose applications where ±0.25% tolerance meets design specifications. Both parts are suitable for direct PCB substitution without layout modifications due to identical package dimensions and termination count.

Frequently Asked Questions (FAQ)

Q: Can the RP73D2B40R2BTDF replace the RT1206CRE0740R2L in existing designs?

A: Yes. Both parts share identical resistance value, package format (1206), power rating (0.25W), and operating temperature range (-55°C to 155°C). The RP73D2B40R2BTDF features improved tolerance (±0.1% versus ±0.25%) and temperature coefficient (±15ppm/°C versus ±50ppm/°C), making it a direct mechanical and electrical substitute.

Q: Are there any dimensional differences between these parts?

A: Dimensions are functionally equivalent. The RT1206CRE0740R2L measures 0.122" L x 0.063" W (3.10mm x 1.60mm), while the RP73D2B40R2BTDF measures 0.120" L x 0.061" W (3.05mm x 1.55mm). Both have identical maximum seated height of 0.026" (0.65mm). These minor variations do not affect PCB layout or assembly compatibility.

Q: What is the significance of the improved tolerance in the RP73D2B40R2BTDF?

A: The ±0.1% tolerance of the RP73D2B40R2BTDF provides tighter resistance accuracy compared to the ±0.25% tolerance of the RT1206CRE0740R2L. This improvement is relevant for precision measurement circuits, calibration networks, and applications where resistance accuracy directly impacts system performance.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both the RT1206CRE0740R2L and RP73D2B40R2BTDF are ROHS3 compliant, REACH unaffected, and carry MSL 1 (Unlimited) moisture sensitivity rating. Both are classified under ECCN EAR99 and HTSUS 8533.21.0030.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts operate across the identical temperature range of -55°C to 155°C. The RP73D2B40R2BTDF offers superior temperature stability with ±15ppm/°C coefficient versus ±50ppm/°C for the RT1206CRE0740R2L, making it preferable for applications requiring minimal resistance drift across temperature extremes.
