Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07140KL is determined by the following mandatory parameters:

• Resistance value: 140 kOhms (exact match required)
• Package type: 1206 (3216 Metric) (exact match required)
• Power rating: 0.25W minimum (equal or higher acceptable)
• Composition: Thin film (maintains electrical performance characteristics)
• Operating temperature range: -55°C to 155°C minimum (equal or wider acceptable)
• RoHS compliance: ROHS3 Compliant (required for regulatory alignment)

Tolerance and temperature coefficient may vary within acceptable engineering margins. Identified substitutes meet all mandatory parameters and are available from active production lines.

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD07140KL (YAGEO) is a direct upgrade substitute offering improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C) while maintaining identical package, power rating, and operating temperature range. Both components are from the same manufacturer and active production status.

ERA-8AEB1403V (Panasonic Electronic Components) provides equivalent electrical performance with AEC-Q200 automotive qualification. This component is suitable for applications requiring automotive-grade reliability and traceability. Physical dimensions vary slightly (0.126" L x 0.063" W versus 0.122" L x 0.063" W), with maximum seated height of 0.028" versus 0.026". All three components maintain ROHS3 compliance and unlimited moisture sensitivity rating.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD07140KL replace RT1206FRE07140KL in all applications?

A: Yes. RT1206BRD07140KL meets all mandatory substitution parameters: identical 140 kOhms resistance, 1206 package, 0.25W power rating, thin film composition, and -55°C to 155°C operating range. The improved tolerance and lower temperature coefficient represent performance enhancements with no compatibility restrictions.

Q: What is the primary difference between RT1206BRD07140KL and ERA-8AEB1403V?

A: Both offer ±0.1% tolerance and ±25ppm/°C temperature coefficient. ERA-8AEB1403V includes AEC-Q200 automotive qualification and has slightly larger physical dimensions (0.126" L x 0.028" H versus 0.122" L x 0.026" H). Selection depends on automotive requirement and PCB layout constraints.

Q: Are physical dimension differences between ERA-8AEB1403V and RT1206FRE07140KL critical?

A: Dimension variations are minor within 1206 package classification. Length difference is 0.004" (0.10mm) and height difference is 0.002" (0.05mm). Verify PCB footprint and assembly clearances for space-constrained applications.

Q: Do all three parts require identical soldering profiles?

A: All three components are 1206 package thin film resistors with MSL 1 rating. Standard SMD soldering processes apply uniformly. Consult individual manufacturer datasheets for specific reflow temperature recommendations.

Q: Which substitute is recommended for new designs?

A: Selection depends on application requirements. For general-purpose circuits, RT1206BRD07140KL provides superior tolerance and temperature stability. For automotive applications, ERA-8AEB1403V provides required AEC-Q200 qualification.
