Substitute Part Grouping Explanation

Substitute parts for the AT1206DRD0723K2L are qualified based on the following criteria:

• Identical resistance value: 23.2 kOhms
• Compatible package: 1206 (3216 Metric)
• Matching composition: Thin Film
• Equivalent temperature coefficient: ±25ppm/°C
• Overlapping operating temperature range: -55°C ~ 155°C
• Compliance with RoHS3 and REACH requirements
• Automotive AEC-Q200 qualification (where applicable)

Tolerance and power rating variations are permitted within the constraints of the application circuit. Substitute parts may feature improved tolerance (±0.1%) or increased power rating (1/3W) without compromising circuit functionality when the original design specifications allow such variations.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain active production status and full RoHS3 compliance. Selection between the main part and substitutes depends on specific application requirements:

RT1206BRD0723K2L offers improved tolerance specification (±0.1% versus ±0.5%) while maintaining identical power rating and package dimensions. This part is suitable for applications requiring tighter resistance accuracy. However, this part does not carry AEC-Q200 automotive qualification.

ERA-8AEB2322V provides AEC-Q200 automotive qualification matching the main part, with improved tolerance (±0.1%). Dimensional variation exists: length 0.126" (3.20mm) versus 0.122" (3.10mm) and height 0.028" (0.70mm) versus 0.026" (0.65mm). These minor dimensional differences remain within standard PCB layout tolerances for 1206 package footprints.

RNCF1206DTE23K2 maintains AEC-Q200 automotive qualification and ±0.5% tolerance matching the main part. This part features increased power rating (0.333W versus 0.25W), providing additional thermal margin in power-dissipation-sensitive applications. Dimensional specifications are comparable to the main part.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD0723K2L be used in automotive applications requiring AEC-Q200 qualification?

A: No. RT1206BRD0723K2L does not carry AEC-Q200 automotive qualification. For automotive applications, use ERA-8AEB2322V or RNCF1206DTE23K2.

Q: What is the significance of tolerance differences between ±0.5% and ±0.1%?

A: Tolerance defines the maximum deviation from the nominal 23.2 kOhms resistance value. ±0.5% allows deviation up to ±116 Ohms; ±0.1% restricts deviation to ±23.2 Ohms. Applications with strict circuit performance requirements benefit from tighter tolerance specifications.

Q: Are the dimensional variations of ERA-8AEB2322V compatible with existing PCB layouts?

A: The dimensional differences (0.004" length, 0.002" height) are within standard 1206 package tolerance ranges and do not require PCB footprint modification. Standard 1206 land patterns accommodate these variations.

Q: Why would RNCF1206DTE23K2 be selected over the main part?

A: RNCF1206DTE23K2 provides increased power rating (1/3W versus 1/4W) while maintaining identical resistance, tolerance, and automotive qualification. Selection depends on circuit power dissipation requirements and thermal design margins.

Q: Are all substitute parts available in equivalent packaging formats?

A: All substitute parts are supplied in Tape & Reel (TR) packaging, matching the main part's standard production format.
