Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07453KL is determined by the following mandatory parameters:

• Resistance Value: Must be exactly 453 kOhms
• Package / Case: Must be 1206 (3216 Metric) for PCB footprint compatibility
• Power Rating: Must be minimum 0.25W (1/4W)
• Composition: Thin film construction required for performance consistency
• Operating Temperature Range: Must support -55°C ~ 155°C minimum
• RoHS Compliance: ROHS3 Compliant status required

Two substitute parts meet these criteria. The RT1206BRD07453KL offers improved tolerance (±0.1% vs ±1%) while maintaining identical package and power specifications. The ERA-8AEB4533V from Panasonic provides the same tolerance upgrade with additional automotive AEC-Q200 qualification, suitable for applications requiring automotive-grade reliability.

Parameter Comparison

Engineering Selection Recommendations

RT1206BRD07453KL is the direct equivalent from YAGEO, offering superior tolerance performance (±0.1%) with identical mechanical and thermal specifications. This part is suitable for applications where tighter tolerance control improves circuit performance without requiring automotive qualification.

ERA-8AEB4533V from Panasonic provides equivalent electrical performance with AEC-Q200 automotive qualification. This part is required for automotive applications, industrial systems with stringent reliability requirements, or designs subject to automotive supply chain specifications. The slight dimensional variation (0.126" L vs 0.122" L, 0.028" H vs 0.026" H) remains within standard PCB design tolerances for 1206 footprints.

Both substitute parts are actively produced with substantial inventory availability, ensuring supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can RT1206BRD07453KL be used as a direct drop-in replacement for RT1206FRE07453KL?

A: Yes. Both parts share identical 1206 package dimensions, power rating, and operating temperature range. The RT1206BRD07453KL provides improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it functionally superior with no design modifications required.

Q: What is the primary difference between RT1206BRD07453KL and ERA-8AEB4533V?

A: Both offer ±0.1% tolerance and ±25ppm/°C temperature coefficient. The ERA-8AEB4533V includes AEC-Q200 automotive qualification and has slightly larger dimensions (0.126" L x 0.028" H vs 0.122" L x 0.026" H). Select ERA-8AEB4533V for automotive applications; select RT1206BRD07453KL for general industrial use.

Q: Are there PCB footprint compatibility concerns with ERA-8AEB4533V?

A: The ERA-8AEB4533V dimensions (3.20mm L x 1.60mm W x 0.70mm H) are slightly larger than the standard 1206 footprint (3.10mm L x 1.60mm W x 0.65mm H). Standard 1206 PCB footprints accommodate this variation. Verify footprint clearance in high-density layouts.

Q: Do all three parts meet RoHS3 compliance?

A: Yes. RT1206FRE07453KL, RT1206BRD07453KL, and ERA-8AEB4533V are all ROHS3 Compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Which part should be selected for new designs?

A: For new designs without automotive requirements, RT1206BRD07453KL is recommended due to superior tolerance and temperature coefficient performance. For automotive or AEC-Q200 qualified designs, ERA-8AEB4533V is required.
