Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206DRD07124KL is determined by the following criteria:

Mandatory Compatibility Parameters:

• Resistance value: 124 kOhms (exact match required)
• Package / Case: 1206 (3216 Metric) (exact match required)
• Power rating: 0.25W minimum
• Composition: Thin Film
• Temperature coefficient: ±25ppm/°C
• Operating temperature range: -55°C ~ 155°C minimum
• RoHS compliance: ROHS3 Compliant

Allowable Variation:

• Tolerance: ±0.5% or tighter (lower tolerance values are acceptable upgrades)
• Physical dimensions: Minor variations within supplier device package specifications are acceptable

Two substitute parts meet these criteria: RT1206BRD07124KL (YAGEO, tighter tolerance) and ERA-8AEB1243V (Panasonic, tighter tolerance with automotive AEC-Q200 qualification).

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD07124KL (YAGEO): This substitute offers improved tolerance specification (±0.1% versus ±0.5%) while maintaining identical electrical and mechanical characteristics. Both components are YAGEO RT series products with active production status and equivalent compliance certifications. Selection is appropriate for applications requiring tighter resistance tolerance without automotive qualification requirements.

ERA-8AEB1243V (Panasonic): This substitute provides ±0.1% tolerance with additional AEC-Q200 automotive qualification. Physical dimensions show minor variation (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 specifications. Selection is appropriate for automotive applications or systems requiring automotive-grade component certification.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD07124KL directly replace RT1206DRD07124KL? A: Yes. Both components share identical resistance value, package format, power rating, temperature coefficient, and operating temperature range. The substitute offers improved tolerance (±0.1% versus ±0.5%), making it a direct upgrade for applications where tighter tolerance is beneficial or required.

Q: Is ERA-8AEB1243V compatible with the original RT1206DRD07124KL footprint? A: Yes. Both components use the 1206 (3216 Metric) package. Minor dimensional variations (length 0.126" versus 0.122", height 0.028" versus 0.026") remain within standard 1206 package tolerances and do not affect PCB footprint compatibility.

Q: When should ERA-8AEB1243V be selected over RT1206BRD07124KL? A: ERA-8AEB1243V is selected for automotive applications or systems requiring AEC-Q200 qualification. Both offer ±0.1% tolerance; the Panasonic component provides additional automotive-grade certification.

Q: Are all three parts ROHS3 compliant? A: Yes. RT1206DRD07124KL, RT1206BRD07124KL, and ERA-8AEB1243V are all ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited).

Q: What is the primary difference between the main part and its substitutes? A: The main part (RT1206DRD07124KL) has ±0.5% tolerance. Both substitutes offer ±0.1% tolerance. ERA-8AEB1243V additionally includes AEC-Q200 automotive qualification.
