RT1206FRE07374KL Equivalent & Substitute Parts

Part Overview

The RT1206FRE07374KL is a 374 kOhms ±1% 0.25W chip resistor in 1206 (3216 Metric) package manufactured by YAGEO. This thin film resistor is designed for general-purpose applications requiring moderate tolerance and standard operating temperature range. The part is Active status with ROHS3 compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options while maintaining electrical and mechanical compatibility within specified parameter tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT1206FRE07374KL is determined by the following critical parameters:

• Resistance value: 374 kOhms (exact match required)
• Package type: 1206 (3216 Metric) form factor
• Power rating: 0.25W minimum
• Composition: Thin film construction
• Operating temperature range: -55°C to 155°C minimum coverage
• RoHS compliance: ROHS3 Compliant

The ERA-8AEB3743V qualifies as a substitute based on matching all mandatory parameters. Enhanced specifications (±0.1% tolerance, ±25ppm/°C temperature coefficient, AEC-Q200 automotive qualification) represent performance improvements that do not compromise compatibility with the original part's electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

Both parts maintain Active product status and ROHS3 compliance. The ERA-8AEB3743V provides tighter tolerance specification (±0.1% versus ±1%) and lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), with additional AEC-Q200 automotive qualification. Selection between these parts depends on application-specific tolerance and temperature stability requirements. Mechanical compatibility is confirmed through identical package designation and equivalent termination count.

Frequently Asked Questions (FAQ)

Q: Can ERA-8AEB3743V directly replace RT1206FRE07374KL in existing designs?

A: Yes. Both parts share identical resistance value, power rating, package type, and operating temperature range. Physical dimensions are compatible for PCB assembly. The substitute part meets or exceeds all electrical specifications of the original part.

Q: What are the dimensional differences between these parts?

A: RT1206FRE07374KL measures 0.122" L × 0.063" W (3.10mm × 1.60mm) with 0.026" maximum seated height. ERA-8AEB3743V measures 0.126" L × 0.063" W (3.20mm × 1.60mm) with 0.028" maximum seated height. Both fit the 1206 package footprint with negligible dimensional variance acceptable for standard PCB layouts.

Q: How do tolerance specifications affect circuit performance?

A: The original part specifies ±1% tolerance, while the substitute provides ±0.1% tolerance. This represents improved accuracy in the substitute part. Applications requiring tighter resistance tolerance benefit from the ERA-8AEB3743V specification.

Q: Is AEC-Q200 qualification relevant for non-automotive applications?

A: AEC-Q200 automotive qualification indicates enhanced reliability testing and quality standards. This certification does not restrict use in non-automotive applications and represents additional validation of component performance.

Q: Are both parts available in the same packaging format?

A: Yes. Both parts are supplied in Tape & Reel (TR) packaging suitable for automated assembly processes. Moisture sensitivity level is identical at MSL 1 (Unlimited) for both parts.
