RT0402FRE0748K7L Equivalent & Substitute Parts

Part Overview

The RT0402FRE0748K7L is a 48.7 kOhms ±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 status and ROHS3 compliant with MSL 1 (Unlimited moisture sensitivity level).

Equivalent and substitute parts are identified when design requirements allow for tolerance relaxation, improved performance specifications, or alternative manufacturer sourcing while maintaining electrical and mechanical compatibility within the 0402 package footprint.

Substitute Part Grouping Explanation

Substitution eligibility is determined by the following criteria:

Identical resistance value: 48.7 kOhms
Identical package: 0402 (1005 Metric)
Identical power rating: 0.063W (1/16W)
Identical composition: Thin Film
Identical operating temperature range: -55°C to 155°C
Identical termination count: 2
Identical RoHS and MSL compliance

Substitute parts may differ in:

Tolerance specification (±0.1%, ±0.5% are tighter than ±1%)
Temperature coefficient (±25ppm/°C is tighter than ±50ppm/°C)
Manufacturer identity
Specific series designation
Height variation within package specification (0.35mm to 0.40mm maximum seated height)

Frequently Asked Questions (FAQ)

Q: Can RT0402BRD0748K7L replace RT0402FRE0748K7L in any application?

A: Yes, within the 0402 package footprint. RT0402BRD0748K7L offers superior tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), making it suitable for precision applications. The identical package dimensions and power rating ensure mechanical and thermal compatibility.

Q: What is the difference between RT0402BRD0748K7L and RT0402BRE0748K7L?

A: Both parts share ±0.1% tolerance and identical package specifications. RT0402BRD0748K7L features ±25ppm/°C temperature coefficient, while RT0402BRE0748K7L maintains ±50ppm/°C. Selection depends on temperature stability requirements.

Q: Is ERA-2AEB4872X compatible with standard 0402 PCB layouts?

A: Yes. ERA-2AEB4872X maintains the 0402 (1005 Metric) package designation. The maximum seated height of 0.40mm is within typical PCB assembly tolerances for 0402 components. Verify clearance for applications with height-constrained layouts.

Q: Can I use CPF0402B48K7E1 as a direct drop-in replacement?

A: Yes. CPF0402B48K7E1 maintains identical resistance, power rating, package footprint, and operating temperature range. The ±0.1% tolerance and ±25ppm/°C temperature coefficient represent performance improvements over the original specification.

Q: Which substitute is recommended for automotive applications?

A: ERA-2AEB4872X carries AEC-Q200 automotive qualification. This part is specified for automotive-grade reliability and environmental stress screening.

Q: Are all substitutes ROHS3 compliant?

A: Yes. All listed substitute parts maintain ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the original RT0402FRE0748K7L environmental specifications.
