RT0805CRE0737R4L Equivalent & Substitute Parts

Part Overview

The RT0805CRE0737R4L is a 37.4 Ohm thin film chip resistor manufactured by YAGEO in the 0805 (2012 Metric) package format. This component is rated for 0.125W (1/8W) power dissipation with a tolerance of ±0.25% and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent resistance values, package dimensions, and operating specifications can be maintained while potentially offering improved performance characteristics or enhanced availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RT0805CRE0737R4L is determined by the following critical parameters:

• Resistance value must equal 37.4 Ohms
• Package must be 0805 (2012 Metric) with matching physical dimensions
• Composition must be Thin Film
• Operating temperature range must encompass -55°C to 155°C
• RoHS3 compliance and MSL 1 rating must be maintained

The substitute part 8-1625868-2 (TE Connectivity Passive Product) meets all mandatory substitution criteria. This part maintains identical resistance, package format, and temperature operating range. The substitute offers enhanced tolerance (±0.1% versus ±0.25%) and increased power rating (0.25W versus 0.125W), representing superior electrical performance characteristics within the same physical footprint.

Parameter Comparison

Engineering Selection Recommendations

Both the RT0805CRE0737R4L and 8-1625868-2 maintain Active product status and full ROHS3 compliance with MSL 1 rating, confirming long-term availability and regulatory alignment. The substitute part 8-1625868-2 is electrically and mechanically compatible for direct replacement in 0805 package applications requiring 37.4 Ohm thin film resistors. Selection between these parts should be based on application-specific requirements: the original YAGEO part is suitable for standard tolerance applications, while the TE Connectivity substitute provides enhanced tolerance and power handling capability within identical package constraints.

Frequently Asked Questions (FAQ)

Q: Can 8-1625868-2 be used as a direct replacement for RT0805CRE0737R4L?

A: Yes. Both parts share identical resistance value (37.4 Ohms), package format (0805 / 2012 Metric), composition (Thin Film), and operating temperature range (-55°C to 155°C). Physical dimensions are equivalent with negligible height variation (0.60mm versus 0.65mm maximum seated height).

Q: What are the key differences between these parts?

A: The substitute part 8-1625868-2 offers tighter tolerance (±0.1% versus ±0.25%), lower temperature coefficient (±25ppm/°C versus ±50ppm/°C), and higher power rating (0.25W versus 0.125W). These represent performance enhancements rather than functional differences.

Q: Are both parts RoHS compliant?

A: Yes. Both RT0805CRE0737R4L and 8-1625868-2 are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Will the substitute part fit in the same PCB footprint?

A: Yes. Both parts use the 0805 (2012 Metric) package with matching length (0.079" / 2.00mm) and width (0.049" / 1.25mm). Maximum seated height differs by 0.002" (0.05mm), which is negligible for standard PCB assembly processes.

Q: What is the temperature operating range for both parts?

A: Both parts operate across -55°C to 155°C, ensuring compatibility in equivalent thermal environments.
