Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT1206CRE073KL are qualified based on the following criteria:

Electrical Parameters (Must Match):

• Resistance value: 3 kOhms
• Power rating: 0.25W minimum
• Package type: 1206 (3216 Metric)
• Composition: Thin Film
• Operating temperature range: -55°C to 155°C minimum

Tolerance Consideration: The main part specifies ±0.25% tolerance. Substitute parts with tighter tolerance (±0.1%) are acceptable as they represent improved performance within the same resistance value and package class.

Identified Substitutes:

• RT1206BRD073KL (YAGEO) – Tighter tolerance variant
• ERA-8AEB302V (Panasonic Electronic Components) – Automotive-qualified variant with AEC-Q200 certification

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD073KL (YAGEO): This substitute offers improved tolerance performance (±0.1% versus ±0.25%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical package, power rating, and operating temperature specifications. Both parts are YAGEO thin film resistors with active product status and ROHS3 compliance. Selection is appropriate for applications requiring tighter tolerance control.

ERA-8AEB302V (Panasonic Electronic Components): This substitute provides equivalent electrical specifications with AEC-Q200 automotive qualification. The part maintains ±0.1% tolerance and ±25ppm/°C temperature coefficient. Physical dimensions differ slightly (0.126" L x 0.063" W versus 0.122" L x 0.063" W; height 0.028" versus 0.026"), remaining within 1206 package class specifications. Selection is appropriate for automotive applications or where AEC-Q200 certification is required.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD073KL be used as a direct replacement for RT1206CRE073KL?

A: Yes. Both parts are YAGEO thin film 1206 resistors with 3 kOhms resistance and 0.25W power rating. The RT1206BRD073KL offers tighter tolerance (±0.1% versus ±0.25%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C). Footprint and reflow characteristics are identical.

Q: What is the difference between the YAGEO and Panasonic substitutes?

A: The primary difference is automotive qualification. ERA-8AEB302V carries AEC-Q200 certification, making it suitable for automotive applications. Physical dimensions are slightly larger (0.126" L x 0.063" W x 0.028" H versus 0.122" L x 0.063" W x 0.026" H), but both conform to 1206 package specifications. Electrical performance is equivalent.

Q: Are all three parts interchangeable on the same PCB?

A: Yes, all three parts are mechanically and electrically compatible within 1206 package specifications. PCB footprints designed for 1206 resistors will accommodate all three variants without modification.

Q: Which substitute should be selected for improved circuit stability?

A: Both RT1206BRD073KL and ERA-8AEB302V offer improved temperature stability with ±25ppm/°C coefficient compared to the original ±50ppm/°C. Selection between them depends on whether automotive qualification (AEC-Q200) is required.

Q: Are all parts ROHS3 compliant?

A: Yes. RT1206CRE073KL, RT1206BRD073KL, and ERA-8AEB302V are all ROHS3 compliant with MSL 1 (unlimited moisture sensitivity rating).
