Substitute Part Grouping Explanation

Substitute parts for the RT1206FRE073K92L are qualified based on the following criteria:

• Identical Resistance Value: 3.92 kOhms
• Identical Package: 1206 (3216 Metric)
• Identical Power Rating: 0.25W (1/4W)
• Identical Composition: Thin Film
• Identical Operating Temperature Range: -55°C to 155°C
• Equal or Superior Tolerance: ±1% or better
• Compliance: ROHS3 Compliant, MSL 1

Substitutes are grouped into two categories: direct tolerance upgrades (±0.1%) and automotive-qualified variants (AEC-Q200).

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD073K92L (YAGEO): This substitute provides improved tolerance (±0.1% versus ±1%) and reduced temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical package, power rating, and operating temperature range. Selection is appropriate for applications requiring tighter resistance accuracy without automotive qualification requirements.

ERA-8AEB3921V (Panasonic Electronic Components): This substitute offers identical tolerance and temperature coefficient improvements as the RT1206BRD073K92L, with the addition of AEC-Q200 automotive qualification. Selection is appropriate for automotive applications or systems requiring automotive-grade component reliability. Physical dimensions show minor variation (0.126" L × 0.063" W versus 0.122" L × 0.063" W), with maximum seated height of 0.028" versus 0.026", which must be verified for PCB layout compatibility.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD073K92L replace RT1206FRE073K92L in any application?

A: Yes. The RT1206BRD073K92L is a direct substitute with superior tolerance and temperature coefficient specifications. All mechanical and electrical parameters remain compatible.

Q: What is the primary difference between RT1206BRD073K92L and ERA-8AEB3921V?

A: Both offer identical tolerance (±0.1%) and temperature coefficient (±25ppm/°C). The ERA-8AEB3921V includes AEC-Q200 automotive qualification and has slightly larger physical dimensions (0.126" L × 0.063" W versus 0.122" L × 0.063" W).

Q: Is ERA-8AEB3921V suitable for non-automotive applications?

A: Yes. AEC-Q200 qualification is a superset of general industrial requirements. The ERA-8AEB3921V can be used in any application where RT1206FRE073K92L is specified.

Q: Will ERA-8AEB3921V fit the same PCB footprint as RT1206FRE073K92L?

A: The 1206 package footprint is identical. However, the maximum seated height differs (0.028" versus 0.026"). Verify clearance in your specific PCB assembly design.

Q: Are all three parts ROHS3 compliant?

A: Yes. RT1206FRE073K92L, RT1206BRD073K92L, and ERA-8AEB3921V are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.
