RT0402FRE07261RL Equivalent & Substitute Parts

Part Overview

The RT0402FRE07261RL is a 261 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 Level 1 (unlimited moisture sensitivity).

Substitute parts are identified when equivalent resistance values, power ratings, package dimensions, and operating temperature ranges are maintained while offering improved tolerance specifications or enhanced reliability features such as automotive qualification or anti-sulfur protection.

Key Parameters

Parameter	Value
Resistance	261 Ohms
Tolerance	±1%
Power Rating	0.063W (1/16W)

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Resistance Value: Must be 261 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 cover -55°C to 155°C
Termination Count: Must be 2 terminations
Compliance: Must maintain ROHS3 compliance

All identified substitute parts meet these core electrical and mechanical requirements. Upgrades in tolerance (from ±1% to ±0.1%), temperature coefficient performance, and automotive qualification (AEC-Q200) or anti-sulfur features represent enhanced specifications rather than functional deviations.

Engineering Selection Recommendations

Standard Applications: The RT0402FRE07261RL remains suitable for general-purpose applications where ±1% tolerance and standard thin film performance are acceptable.

Improved Tolerance Requirements: CPF0402B261RE1 and RN73C1E261RBTDF provide ±0.1% tolerance with reduced temperature coefficient drift (±25 ppm/°C and ±10 ppm/°C respectively), supporting precision analog circuits and measurement applications.

Automotive Applications: ERA-2AEB2610X and RG1005P-2610-B-T5 carry AEC-Q200 automotive qualification. RG1005P-2610-B-T5 additionally includes anti-sulfur protection, suitable for harsh automotive environments.

Temperature Stability: RN73C1E261RBTDF exhibits the lowest temperature coefficient (±10 ppm/°C), providing superior stability across the full operating range.

All substitute parts maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with standard PCB assembly processes.

Frequently Asked Questions (FAQ)

Q: Can RT0402FRE07261RL be directly replaced with CPF0402B261RE1?

A: Yes. Both parts share identical resistance (261 Ω), power rating (0.063W), package (0402), and operating temperature range (-55°C to 155°C). CPF0402B261RE1 offers improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25 ppm/°C vs ±50 ppm/°C).

Q: What is the difference between ERA-2AEB2610X and RG1005P-2610-B-T5?

A: Both are AEC-Q200 qualified automotive resistors with ±0.1% tolerance and ±25 ppm/°C temperature coefficient. RG1005P-2610-B-T5 includes anti-sulfur protection for enhanced reliability in corrosive environments. Physical height differs slightly (0.016" vs 0.016" maximum seated height).

Q: Is RN73C1E261RBTDF suitable for high-precision applications?

A: Yes. RN73C1E261RBTDF provides the tightest temperature coefficient specification (±10 ppm/°C) among all listed substitutes, making it appropriate for precision measurement and analog signal conditioning circuits.

Q: Do all substitute parts maintain the same PCB footprint?

A: Yes. All parts use the 0402 (1005 Metric) package with identical land pattern dimensions (0.039" L × 0.020" W). Physical height variations (0.014" to 0.016" maximum seated) are within standard PCB assembly tolerances.

Q: Are substitute parts available in equivalent packaging formats?

A: All listed substitute parts are supplied in Tape & Reel (TR) packaging, matching the original RT0402FRE07261RL format for automated assembly compatibility.
