Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRD07124KL is determined by the following mandatory parameters:

• Resistance Value: Must be 124 kOhms (exact match required)
• Package / Case: Must be 1206 (3216 Metric) for PCB footprint compatibility
• Power Rating: Must be 0.25W (1/4W) minimum
• Composition: Thin film construction required
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C ~ 155°C minimum
• RoHS Compliance: ROHS3 Compliant required
• Moisture Sensitivity Level: MSL 1 (Unlimited) required

Tolerance specifications (±1% or tighter) and additional certifications (such as AEC-Q200) do not restrict substitution but may indicate upgraded performance characteristics suitable for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD07124KL (YAGEO Upgrade): This substitute offers improved tolerance specification (±0.1% versus ±1%) while maintaining identical package dimensions, power rating, and temperature characteristics. Both YAGEO parts share the same 1206 footprint and height profile, enabling direct PCB substitution without layout modifications. Selection is appropriate for applications requiring tighter resistance value control within the same product family.

ERA-8AEB1243V (Panasonic MFR Recommended): This substitute introduces AEC-Q200 automotive qualification, indicating compliance with automotive reliability and environmental stress testing standards. The ERA-8AEB1243V maintains the same electrical specifications (124 kOhms, ±0.1%, 0.25W) and operating temperature range. Physical dimensions show minor variations: length increases from 3.10mm to 3.20mm and height from 0.65mm to 0.70mm. Selection is appropriate for automotive applications or systems requiring automotive-grade component certification. PCB layout verification is recommended due to dimensional differences.

All three parts maintain ROHS3 compliance, MSL Level 1 rating, and active production status, ensuring long-term availability and regulatory consistency.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD07124KL replace RT1206FRD07124KL directly on the PCB?

A: Yes. Both parts share identical 1206 package dimensions (3.10mm x 1.60mm length and width) and maximum seated height (0.65mm). Direct PCB substitution is possible without layout modifications. The tolerance improvement (±0.1% versus ±1%) represents enhanced performance within the same mechanical footprint.

Q: Is ERA-8AEB1243V a direct substitute for RT1206FRD07124KL?

A: ERA-8AEB1243V is electrically compatible but requires PCB layout verification. Length increases from 3.10mm to 3.20mm and height from 0.65mm to 0.70mm. These dimensional differences may affect placement in space-constrained designs. Verify available PCB clearance before substitution.

Q: What determines whether a part can substitute for RT1206FRD07124KL?

A: Substitution requires matching resistance value (124 kOhms), package format (1206), power rating (0.25W minimum), thin film composition, temperature coefficient (±25ppm/°C), operating range (-55°C to 155°C), and compliance certifications (ROHS3, MSL 1). Tolerance specifications may vary without affecting substitution eligibility.

Q: When should I select the AEC-Q200 rated ERA-8AEB1243V?

A: Select ERA-8AEB1243V for automotive applications, systems requiring automotive-grade component certification, or designs subject to automotive reliability standards. The AEC-Q200 qualification indicates compliance with automotive environmental stress testing and reliability requirements.

Q: Are all three parts currently available?

A: Yes. RT1206FRD07124KL has 1002 units in stock, RT1206BRD07124KL has 1123 units, and ERA-8AEB1243V has 3724 units available. All parts maintain active production status.
