RT0402FRE07348RL Equivalent & Substitute Parts

Part Overview

The RT0402FRE07348RL is a 348 Ohm ±1% thin film chip resistor in 0402 (1005 Metric) package manufactured by YAGEO. This surface mount resistor is rated for 0.063W (1/16W) power dissipation and operates across -55°C to 155°C. The part is ROHS3 compliant and carries MSL 1 (Unlimited) moisture sensitivity rating, making it suitable for general industrial and commercial applications. Substitute parts are identified when equivalent electrical performance, mechanical compatibility, and compliance requirements can be maintained while offering improved tolerance, temperature coefficient performance, or enhanced availability.

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE07348RL is determined by the following mandatory parameters:

Resistance Value: Must be 348 Ohms
Package Type: Must be 0402 (1005 Metric)
Power Rating: Must be 0.063W (1/16W) minimum
Composition: Must be Thin Film
Operating Temperature Range: Must support -55°C to 155°C minimum
Moisture Sensitivity: Must be MSL 1 or better

Substitute parts identified in this reference meet all mandatory parameters. Improvements in tolerance (±0.1% vs ±1%), temperature coefficient (±10ppm/°C to ±25ppm/°C vs ±50ppm/°C), and manufacturer availability represent performance enhancements or supply chain alternatives rather than functional deviations.

Engineering Selection Recommendations

Primary Substitutes (ROHS3 Compliant, Enhanced Performance)

RT0402BRD07348RL (YAGEO) and ERA-2AEB3480X (Panasonic) are direct upgrades offering ±0.1% tolerance and ±25ppm/°C temperature coefficient with full ROHS3 compliance. RT0402BRD07348RL provides the highest inventory availability (37,557 pcs). ERA-2AEB3480X includes AEC-Q200 automotive qualification and is suitable for applications requiring automotive-grade reliability.

High-Precision Alternative

RN73C1E348RBTDF (TE Connectivity) delivers the lowest temperature coefficient (±10ppm/°C) and ±0.1% tolerance for applications requiring superior stability. Limited inventory (899 pcs) may affect lead time.

Compliance Consideration

CPF0402B348RE1 (TE Connectivity) meets electrical and mechanical specifications but carries RoHS non-compliant status. Selection requires verification against end-product compliance requirements.

Temperature-Limited Alternative

RR0510P-3480-D (Susumu) operates to 125°C maximum (vs. 155°C for primary part) with ±0.5% tolerance. Suitable only for applications not exceeding 125°C operating temperature.

Frequently Asked Questions (FAQ)

Q: Can RT0402BRD07348RL replace RT0402FRE07348RL in existing designs?

A: Yes. Both parts share identical 348 Ohm resistance, 0402 package, 0.063W power rating, and -55°C to 155°C operating range. RT0402BRD07348RL offers improved ±0.1% tolerance and ±25ppm/°C temperature coefficient compared to the original ±1% and ±50ppm/°C specifications. No circuit redesign is required.

Q: What is the difference between ERA-2AEB3480X and other substitutes?

A: ERA-2AEB3480X includes AEC-Q200 automotive qualification and carries Panasonic's automotive-grade reliability designation. This part is specified for applications requiring automotive-level quality assurance. Electrical parameters (348 Ω, ±0.1%, 0.063W) are equivalent to RT0402BRD07348RL.

Q: Is RR0510P-3480-D suitable for all applications?

A: RR0510P-3480-D operates to 125°C maximum, which is 30°C below the original part's 155°C rating. This part is suitable only for applications with maximum operating temperatures not exceeding 125°C. Verify thermal requirements before selection.

Q: Why is CPF0402B348RE1 listed if it is RoHS non-compliant?

A: CPF0402B348RE1 meets all electrical and mechanical substitution criteria. However, RoHS non-compliance status requires verification against end-product regulatory requirements. Selection depends on whether the application or end market mandates RoHS compliance.

Q: What is the significance of temperature coefficient differences?

A: Temperature coefficient indicates resistance value drift across the operating temperature range. RN73C1E348RBTDF (±10ppm/°C) exhibits minimal drift, making it suitable for precision analog circuits. RT0402FRE07348RL (±50ppm/°C) is acceptable for general-purpose applications where tolerance stack-up is not critical.

Q: Are all substitute parts available in Tape & Reel packaging?

A: Yes. All identified substitutes are supplied in Tape & Reel (TR) packaging, maintaining compatibility with automated assembly processes.
