RT0402FRE07174RL Equivalent & Substitute Parts

Part Overview

The RT0402FRE07174RL is a 174 Ohm ±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 in production and ROHS3 compliant, making it suitable for standard commercial and industrial applications requiring precision resistive elements.

Substitute parts are necessary when the original manufacturer's stock is unavailable, when design requirements demand tighter tolerance specifications, or when application-specific certifications such as automotive qualification are required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0402FRE07174RL is determined by the following mandatory parameters:

• Resistance value: 174 Ohms (exact match required)
• Package type: 0402 (1005 Metric) (exact match required)
• Power rating: 0.063W minimum (equal or higher acceptable)
• Composition: Thin Film (exact match required)
• Operating temperature range: -55°C to 155°C minimum (equal or wider acceptable)
• RoHS compliance: ROHS3 (required for regulatory compatibility)

The substitute parts listed below meet all mandatory parameters. Tolerance and temperature coefficient specifications are tighter in the substitute options, providing enhanced performance characteristics while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

All substitute parts maintain full electrical and mechanical compatibility with the RT0402FRE07174RL. Selection among the available options depends on application-specific requirements:

CPF0402B174RE1 provides improved tolerance (±0.1%) and reduced temperature coefficient (±25ppm/°C) compared to the original part, suitable for applications requiring enhanced precision without automotive qualification requirements.

ERA-2AEB1740X offers the same tolerance and temperature coefficient improvements as CPF0402B174RE1 while adding AEC-Q200 automotive qualification. This part is appropriate for automotive and mission-critical applications where industry-standard reliability ratings are mandatory. The maximum seated height is 0.016" (0.40mm), which is 0.002" taller than the original specification.

RN73C1E174RBTDF delivers the tightest temperature coefficient specification (±10ppm/°C) among all options, combined with ±0.1% tolerance. This part is suitable for high-precision analog circuits and applications with stringent temperature stability requirements.

All parts are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity rating, ensuring compatibility with standard manufacturing and storage practices.

Frequently Asked Questions (FAQ)

Q: Can I use ERA-2AEB1740X as a direct replacement if my PCB layout is already finalized?

A: ERA-2AEB1740X has a maximum seated height of 0.016" (0.40mm) compared to 0.014" (0.35mm) for the original RT0402FRE07174RL. If your PCB design includes height-constrained areas or clearance specifications, this 0.002" difference must be evaluated. For most standard applications, this height variation is acceptable.

Q: What is the practical difference between ±1% and ±0.1% tolerance in circuit operation?

A: Tolerance specifications define the maximum deviation from the nominal resistance value. At 174 Ohms, ±1% tolerance allows deviation up to ±1.74 Ohms, while ±0.1% tolerance limits deviation to ±0.174 Ohms. Selection depends on circuit sensitivity to resistance variation. Precision analog circuits, measurement instrumentation, and high-gain amplifier networks typically require ±0.1% tolerance.

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

A: AEC-Q200 is an automotive industry standard for passive component reliability. For non-automotive applications, this certification is not required. However, ERA-2AEB1740X remains fully compatible with standard commercial and industrial applications and offers no disadvantage when used outside automotive contexts.

Q: Are all substitute parts available in the same packaging format?

A: All substitute parts are supplied in Tape & Reel (TR) packaging, matching the original RT0402FRE07174RL format. This ensures compatibility with standard pick-and-place assembly equipment and manufacturing workflows.

Q: What does temperature coefficient (ppm/°C) mean for resistor selection?

A: Temperature coefficient specifies how much the resistance value changes per degree Celsius of temperature variation. The RT0402FRE07174RL has ±50ppm/°C, meaning resistance can shift by up to 50 parts per million per degree. Substitute parts with ±25ppm/°C or ±10ppm/°C provide improved stability across the -55°C to 155°C operating range, beneficial for applications with wide temperature exposure or precision requirements.
