RT0805FRE0747R5L Equivalent & Substitute Parts

Part Overview

The RT0805FRE0747R5L is a 47.5 Ohm ±1% thin film chip resistor in 0805 (2012 Metric) package format, rated for 0.125W (1/8W) power dissipation. Manufactured by YAGEO under the RT series, this component is actively produced and ROHS3 compliant. Finding equivalent and substitute parts becomes necessary when addressing supply chain constraints, inventory availability, or specific application requirements that may benefit from enhanced tolerance or power ratings while maintaining the same footprint and electrical characteristics.

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805FRE0747R5L is determined by the following critical parameters:

• Resistance Value: Must be 47.5 Ohms (exact match required)
• Package Format: Must be 0805 (2012 Metric) to ensure PCB footprint compatibility
• Composition: Thin film construction maintains electrical performance characteristics
• Operating Temperature Range: Must support -55°C ~ 155°C minimum
• RoHS Compliance: ROHS3 compliance required for regulatory alignment
• Moisture Sensitivity: MSL 1 rating ensures handling compatibility

Tolerance, power rating, and temperature coefficient may vary within acceptable engineering parameters, provided the substitute part meets or exceeds the minimum specifications of the original component. Two substitute parts meet these criteria:

1. 9-1625868-2 (TE Connectivity) – Direct substitute with improved tolerance (±0.1%) and higher power rating (0.25W)
2. ERA-6AEB47R5V (Panasonic) – Upgrade substitute with improved tolerance (±0.1%), automotive AEC-Q200 qualification, and equivalent power rating (0.125W)

Parameter Comparison

Engineering Selection Recommendations

9-1625868-2 (TE Connectivity RP73P Series) is suitable for applications requiring enhanced tolerance performance (±0.1% versus ±1%) and higher power dissipation capability (0.25W versus 0.125W). This substitute provides improved thermal headroom and precision, maintaining identical package dimensions and full ROHS3 compliance. Selection is appropriate when circuit design margins benefit from tighter resistance tolerance or when thermal stress analysis indicates higher power dissipation potential.

ERA-6AEB47R5V (Panasonic ERA-6A Series) is the preferred substitute for automotive and mission-critical applications. This part carries AEC-Q200 automotive qualification, indicating compliance with automotive reliability and environmental standards. It provides ±0.1% tolerance with equivalent 0.125W power rating and maintains identical package footprint. The lower temperature coefficient (±25ppm/°C versus ±50ppm/°C) delivers superior temperature stability. Selection is mandatory for automotive applications and recommended for high-reliability industrial designs.

Both substitutes maintain full compatibility with the original RT0805FRE0747R5L in terms of PCB footprint, soldering process, and operating environment.

Frequently Asked Questions (FAQ)

Q: Can 9-1625868-2 be used as a direct replacement for RT0805FRE0747R5L?

A: Yes. Both components share identical resistance value (47.5 Ohms), package format (0805), composition (thin film), and operating temperature range (-55°C ~ 155°C). The substitute offers improved tolerance (±0.1% versus ±1%) and higher power rating (0.25W versus 0.125W), making it electrically and mechanically compatible. No PCB redesign is required.

Q: What is the difference between the two substitute parts?

A: The primary differences are power rating and automotive qualification. The 9-1625868-2 provides 0.25W power rating with ±0.1% tolerance. The ERA-6AEB47R5V maintains the original 0.125W power rating but includes AEC-Q200 automotive qualification and a lower temperature coefficient (±25ppm/°C). Both offer ±0.1% tolerance and identical package dimensions.

Q: Is ERA-6AEB47R5V suitable for non-automotive applications?

A: Yes. ERA-6AEB47R5V meets all general industrial specifications and exceeds the performance requirements of the original RT0805FRE0747R5L. The automotive qualification (AEC-Q200) indicates enhanced reliability and environmental testing, making it suitable for any application requiring high reliability. It is not restricted to automotive use.

Q: Will the substitute parts fit the same PCB footprint?

A: Yes. All three parts use the 0805 (2012 Metric) package format with identical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm). Physical footprint compatibility is guaranteed. Maximum seated height varies slightly (0.024" to 0.026"), which does not affect PCB assembly or clearance in standard designs.

Q: Are there any compliance or certification differences?

A: All three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. The ERA-6AEB47R5V additionally carries AEC-Q200 automotive qualification. The 9-1625868-2 lists REACH status as "Vendor Undefined" compared to "REACH Unaffected" for the original and Panasonic parts. For applications requiring explicit REACH compliance documentation, the original RT0805FRE0747R5L or ERA-6AEB47R5V are recommended.

Q: Can tolerance differences affect circuit performance?

A: Tolerance differences (±1% versus ±0.1%) affect circuit accuracy and stability. The original ±1% tolerance allows resistance variation of ±0.475 Ohms. Substitute parts with ±0.1% tolerance limit variation to ±0.0475 Ohms. Applications with tight impedance matching, precision signal conditioning, or feedback networks benefit from the improved tolerance of substitute parts. Standard applications are unaffected by this difference.
