RT0402FRE0748R7L Equivalent & Substitute Parts

Part Overview

The RT0402FRE0748R7L is a 48.7 Ohm ±1% thin film chip resistor in 0402 (1005 Metric) package manufactured by YAGEO. This component is actively produced and widely used in precision analog circuits, signal conditioning, and measurement applications where the 0402 form factor and thin film composition are required. Substitute parts are identified to address inventory availability, lead time constraints, or specific application requirements while maintaining electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitute parts for the RT0402FRE0748R7L are qualified based on the following criteria:

• Resistance Value: Exact match at 48.7 Ohms
• Package Type: 0402 (1005 Metric) form factor required for PCB footprint compatibility
• Composition: Thin film construction to maintain electrical performance characteristics
• Power Rating: 0.063W (1/16W) minimum
• Operating Temperature Range: -55°C to 155°C minimum
• Compliance: ROHS3 compliant, MSL 1 rating

The identified substitutes meet or exceed these parameters. Tolerance improvements (±0.1% vs ±1%) and temperature coefficient enhancements represent performance upgrades rather than functional requirements for substitution.

Parameter Comparison

Engineering Selection Recommendations

RT0402FRE0748R7L (YAGEO): Primary choice for standard industrial applications. Active product status with established supply chain. Suitable for general-purpose precision analog circuits.

CPF0402B48R7E1 (TE Connectivity): Direct upgrade option offering improved tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C). Maintains identical package dimensions and power rating. Recommended when tighter tolerance specifications are required or YAGEO inventory is unavailable.

ERA-2AEB48R7X (Panasonic): Automotive-grade alternative with AEC-Q200 qualification. Provides ±0.1% tolerance and ±25ppm/°C temperature coefficient. Maximum seated height is 0.016" (0.40mm) versus 0.014" (0.35mm) for other options. Select this part only when automotive qualification is a design requirement or when high-volume automotive supply chain access is necessary.

Frequently Asked Questions (FAQ)

Q: Can CPF0402B48R7E1 directly replace RT0402FRE0748R7L on existing PCBs?

A: Yes. Both parts share identical 0402 package dimensions, footprint, and electrical ratings. The CPF0402B48R7E1 offers improved tolerance and temperature coefficient as performance enhancements.

Q: Is ERA-2AEB48R7X compatible with standard 0402 PCB layouts?

A: The ERA-2AEB48R7X is mechanically compatible with 0402 footprints. However, its maximum seated height is 0.40mm compared to 0.35mm for the other options. Verify PCB clearance specifications if height-constrained applications are involved.

Q: What is the primary difference between these three parts?

A: All three parts deliver 48.7 Ohms at 0.063W in 0402 package. The RT0402FRE0748R7L has ±1% tolerance and ±50ppm/°C temperature coefficient. Both substitutes offer ±0.1% tolerance and ±25ppm/°C temperature coefficient. The ERA-2AEB48R7X adds AEC-Q200 automotive qualification.

Q: Which substitute should be used for cost optimization?

A: Selection should be based on availability and application requirements rather than cost alone. All three parts are active products. The RT0402FRE0748R7L and CPF0402B48R7E1 are functionally equivalent for non-automotive applications.

Q: Are all parts RoHS3 compliant?

A: Yes. All three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating, suitable for standard PCB assembly and storage conditions.
