RT0805FRE07390KL Equivalent & Substitute Parts

Part Overview

The RT0805FRE07390KL is a 390 kOhms ±1% thin film chip resistor in 0805 (2012 Metric) package manufactured by YAGEO. This surface-mount device is rated for 0.125W (1/8W) power dissipation with an operating temperature range of -55°C to 155°C. The part is ROHS3 compliant and carries MSL Level 1 (Unlimited) moisture sensitivity rating, indicating suitability for standard storage and handling conditions.

Substitute parts are identified based on matching the core electrical specifications: 390 kOhms resistance value, 0805 package footprint, 0.125W power rating, and -55°C to 155°C operating temperature range. Alternative parts may offer improved tolerance grades (±0.1% versus ±1%), enhanced temperature coefficients, or automotive-grade certifications while maintaining full mechanical and electrical compatibility.

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following core parameters:

Resistance Value: Must be 390 kOhms
Package Footprint: Must be 0805 (2012 Metric)
Power Rating: Must be 0.125W (1/8W) minimum
Operating Temperature Range: Must span -55°C to 155°C
Composition: Thin film construction
Termination Count: 2 terminations
Physical Dimensions: 0.079" L × 0.049" W (2.00mm × 1.25mm)

All identified substitute parts meet these mandatory criteria. Variations in tolerance grade (±0.1% versus ±1%), temperature coefficient (±10ppm/°C to ±50ppm/°C), and certifications (automotive AEC-Q200, anti-sulfur features) represent performance enhancements or specialized qualifications that do not affect direct substitutability in standard applications.

Engineering Selection Recommendations

All substitute parts listed maintain full compatibility with the RT0805FRE07390KL in terms of footprint, electrical performance envelope, and regulatory compliance. Selection among alternatives should be based on application-specific requirements:

YAGEO RT0805BRD07390KL and RT0805BRE07390KL: Direct YAGEO alternatives offering improved tolerance (±0.1%) and maintained ROHS3 compliance. RT0805BRD07390KL provides superior temperature coefficient (±25ppm/°C) for precision applications.

Panasonic ERA-6AEB394V: Suitable for automotive applications requiring AEC-Q200 qualification. Offers ±0.1% tolerance and ±25ppm/°C temperature coefficient with ROHS3 compliance.

Susumu RG2012N-394-B-T5 and RG2012P-394-B-T5: Automotive-grade alternatives with anti-sulfur features and AEC-Q200 certification. RG2012N-394-B-T5 provides the lowest temperature coefficient (±10ppm/°C) and reduced maximum height (0.50mm). Both maintain ROHS3 compliance.

All parts carry MSL Level 1 (Unlimited) moisture sensitivity and REACH Unaffected status, ensuring equivalent handling and storage requirements.

Frequently Asked Questions (FAQ)

Q: Can RT0805BRD07390KL replace RT0805FRE07390KL directly?

A: Yes. Both parts share identical 390 kOhms resistance, 0805 package footprint, 0.125W power rating, and -55°C to 155°C operating temperature range. RT0805BRD07390KL offers improved tolerance (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), making it a direct upgrade with no circuit modifications required.

Q: What is the difference between RG2012N-394-B-T5 and RG2012P-394-B-T5?

A: Both Susumu parts are electrically and mechanically equivalent with identical 390 kOhms resistance, ±0.1% tolerance, and 0805 package. The primary difference is temperature coefficient: RG2012N-394-B-T5 specifies ±10ppm/°C while RG2012P-394-B-T5 specifies ±25ppm/°C. Both include anti-sulfur treatment and AEC-Q200 automotive certification.

Q: Are automotive-grade parts (ERA-6AEB394V, RG2012N-394-B-T5, RG2012P-394-B-T5) suitable for non-automotive applications?

A: Yes. Automotive-grade parts with AEC-Q200 certification meet or exceed standard industrial specifications and are fully compatible with non-automotive circuits. Their enhanced reliability and environmental stress screening make them suitable for any application requiring the 390 kOhms, 0805 package specification.

Q: Does the reduced height of Susumu parts (0.50mm versus 0.60mm) affect PCB layout?

A: No. The 0.10mm height reduction is within standard PCB assembly tolerances and does not require layout modifications. Both height specifications are compatible with standard 0805 package footprints.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All listed substitute parts carry ROHS3 Compliant status and REACH Unaffected designation, matching the compliance profile of the RT0805FRE07390KL.
