Key Parameters

Substitute Part Grouping Explanation

The ERA-8AEB3092V qualifies as a substitute for the RT1206FRE0730K9L based on the following alignment of critical parameters:

• Identical resistance value: 30.9 kOhms
• Identical package format: 1206 (3216 Metric)
• Identical power rating: 0.25W (1/4W)
• Identical composition: Thin Film
• Identical operating temperature range: -55°C ~ 155°C
• Identical RoHS3 compliance and MSL rating

The ERA-8AEB3092V provides enhanced tolerance (±0.1% versus ±1%) and improved temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it suitable for applications requiring tighter specifications while maintaining full mechanical and thermal compatibility.

Parameter Comparison

Engineering Selection Recommendations

Both the RT1206FRE0730K9L and ERA-8AEB3092V are active products with ROHS3 compliance and identical MSL ratings. The ERA-8AEB3092V carries AEC-Q200 automotive qualification, which provides additional reliability assurance for demanding applications. Selection between these parts should be based on tolerance and temperature coefficient requirements specific to the circuit design. The dimensional variance (0.04mm length difference, 0.02mm height difference) is negligible for standard PCB layouts using 1206 footprints.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB3092V replace RT1206FRE0730K9L in any application?

A: Yes, from an electrical and mechanical standpoint. The ERA-8AEB3092V meets or exceeds all critical parameters. However, verify that your design does not specifically require the ±1% tolerance specification; the ERA-8AEB3092V's ±0.1% tolerance is tighter and suitable for precision applications.

Q: What is the significance of the tolerance difference?

A: The RT1206FRE0730K9L has ±1% tolerance, while the ERA-8AEB3092V has ±0.1% tolerance. This means the ERA-8AEB3092V maintains resistance values within a narrower range, beneficial for circuits requiring high precision. If your application specifies ±1% tolerance as a maximum acceptable variance, the ERA-8AEB3092V is fully compatible.

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

A: Both parts use the 1206 (3216 Metric) package. Minor dimensional differences (0.04mm in length, 0.02mm in height) are within standard PCB design tolerances and do not require layout modifications.

Q: What does AEC-Q200 qualification mean?

A: AEC-Q200 is an automotive industry standard qualification indicating the ERA-8AEB3092V has been tested and validated for automotive applications. This certification is not required for general-purpose use but indicates enhanced reliability testing.

Q: Are both parts currently available?

A: Yes. The RT1206FRE0730K9L has 945 pieces in stock, and the ERA-8AEB3092V has 4748 pieces in stock as new original inventory.
