Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE07681KL is determined by the following critical parameters:

• Resistance value: 681 kOhms (exact match required)
• Package format: 0805 (2012 Metric) (exact match required)
• Power rating: 0.125W minimum (equal or higher acceptable)
• Composition: Thin film (maintains electrical characteristics)
• Operating temperature range: -55°C ~ 155°C minimum (equal or wider acceptable)
• RoHS3 compliance: Required for regulatory compatibility
• Moisture sensitivity: MSL 1 (Unlimited) preferred for handling consistency

The identified substitute part RT0805BRD07681KL meets all substitution criteria with an upgrade in tolerance specification (±0.1% versus ±1%), providing improved precision while maintaining all other functional and compliance parameters.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD07681KL replace RT0805FRE07681KL in existing designs?

A: Yes. Both components share identical resistance values, package formats (0805), power ratings (0.125W), operating temperature ranges (-55°C ~ 155°C), and physical dimensions. The substitute offers improved tolerance (±0.1% versus ±1%) and lower temperature coefficient, making it a direct functional replacement.

Q: What is the primary difference between these two parts?

A: The RT0805BRD07681KL provides tighter tolerance (±0.1%) and improved temperature stability (±25ppm/°C) compared to the RT0805FRE07681KL (±1% tolerance, ±50ppm/°C). Both maintain identical electrical power ratings and package specifications.

Q: Are there any PCB layout or assembly considerations when switching between these parts?

A: No. Both components use the 0805 (2012 Metric) package with identical dimensions (2.00mm x 1.25mm length, 1.25mm width, 0.60mm maximum seated height). PCB footprints, reflow profiles, and assembly processes remain unchanged.

Q: Do both parts meet current compliance standards?

A: Yes. Both RT0805FRE07681KL and RT0805BRD07681KL are RoHS3 compliant, REACH Unaffected, and classified under ECCN EAR99 with identical HTSUS codes (8533.21.0030).

Q: Which part should be selected for precision analog circuits?

A: The RT0805BRD07681KL is the appropriate selection for precision applications due to its ±0.1% tolerance specification and lower temperature coefficient (±25ppm/°C), providing superior resistance stability across the operating temperature range.
