RT0402FRE07340RL Equivalent & Substitute Parts

Part Overview

The RT0402FRE07340RL is a 340 Ohms ±1% thin film chip resistor in 0402 (1005 Metric) package manufactured by YAGEO. This surface mount device is rated for 0.063W (1/16W) power dissipation and operates across -55°C to 155°C. The part is active and ROHS3 compliant with MSL 1 rating, making it suitable for general industrial and commercial applications requiring standard tolerance resistive elements.

Substitute parts are identified based on matching the core electrical specifications: 340 Ohms resistance value, 0402 package footprint, identical physical dimensions, and compatible operating temperature range. Alternative manufacturers offer equivalent or upgraded tolerance grades that maintain functional compatibility while providing enhanced precision or automotive-grade reliability options.

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE07340RL is determined by the following mandatory parameters:

Resistance value: 340 Ohms (exact match required)
Package type: 0402 (1005 Metric) footprint
Physical dimensions: 0.039" L x 0.020" W (1.00mm x 0.50mm)
Operating temperature range: -55°C to 155°C minimum
Composition: Thin film construction
Power rating: 0.063W (1/16W) or higher
Termination count: 2 terminations

All identified substitute parts meet these core requirements. Tolerance grades vary from ±1% (main part) to ±0.1% (upgrade options), representing improved precision without affecting functional compatibility. Temperature coefficient specifications range from ±50ppm/°C to ±10ppm/°C, with lower values indicating superior stability. One substitute (ERA-2AEB3400X) includes automotive AEC-Q200 qualification for applications requiring enhanced reliability standards.

Engineering Selection Recommendations

All substitute parts maintain active product status and ROHS3 compliance, ensuring continued availability and environmental regulatory conformance.

RT0402BRD07340RL (YAGEO) provides direct manufacturer upgrade with improved ±0.1% tolerance and reduced temperature coefficient (±25ppm/°C) while maintaining identical package dimensions and height profile.

CPF0402B340RE1 (TE Connectivity Neohm series) delivers equivalent ±0.1% tolerance specification with identical thermal characteristics and footprint compatibility.

ERA-2AEB3400X (Panasonic ERA-2A series) is the only substitute qualified to automotive AEC-Q200 standard, suitable for applications requiring enhanced reliability and automotive-grade component certification. Height is 0.40mm maximum versus 0.35mm for other options.

RN73C1E340RBTDF (TE Connectivity Holsworthy series) offers the lowest temperature coefficient specification at ±10ppm/°C, providing superior long-term stability for precision applications requiring minimal drift across the operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can RT0402BRD07340RL replace RT0402FRE07340RL directly?

A: Yes. Both parts share identical 340 Ohms resistance, 0402 package footprint, physical dimensions (1.00mm x 0.50mm), and operating temperature range (-55°C to 155°C). The substitute offers improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it a direct upgrade with no circuit redesign required.

Q: What is the difference between the substitute parts?

A: All substitutes maintain 340 Ohms resistance and 0402 package compatibility. Primary differences are tolerance grade (all ±0.1%), temperature coefficient (ranging from ±10ppm/°C to ±25ppm/°C), and certifications. ERA-2AEB3400X includes AEC-Q200 automotive qualification. RN73C1E340RBTDF provides the tightest temperature coefficient specification.

Q: Is ERA-2AEB3400X compatible with standard PCB layouts?

A: Yes. ERA-2AEB3400X maintains the 0402 (1005 Metric) footprint and 1.00mm x 0.50mm dimensions. Maximum seated height is 0.40mm versus 0.35mm for other options. This 0.05mm difference is within standard PCB assembly tolerances and does not affect component placement or board clearance in typical designs.

Q: Which substitute offers the best temperature stability?

A: RN73C1E340RBTDF provides the lowest temperature coefficient at ±10ppm/°C, compared to ±25ppm/°C for other substitutes and ±50ppm/°C for the main part. This specification indicates superior resistance value stability across the -55°C to 155°C operating range.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All identified substitute parts carry ROHS3 compliance certification, maintaining environmental regulatory conformance equivalent to the main part.
