RT0805FRE0748R7L Equivalent & Substitute Parts

Part Overview

The RT0805FRE0748R7L is a 48.7 Ohm ±1% thin film chip resistor in 0805 (2012 Metric) package manufactured by YAGEO. This surface mount resistor is rated for 0.125W (1/8W) power dissipation with a temperature coefficient of ±50ppm/°C and operates across -55°C to 155°C. The component is ROHS3 compliant with MSL 1 rating and is currently in active production status. Equivalent and substitute parts are identified based on matching resistance value, package format, and electrical performance parameters within acceptable tolerance and power rating specifications.

Substitute Part Grouping Explanation

Substitute parts for the RT0805FRE0748R7L are qualified based on the following criteria:

Core Matching Parameters:

• Resistance value: 48.7 Ohms (exact match required)
• Package format: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Operating temperature range: -55°C to 155°C (minimum requirement)
• RoHS compliance: ROHS3 Compliant (minimum requirement)

Allowable Variations:

• Tolerance: Equal to or tighter than ±1%
• Power rating: Equal to or greater than 0.125W
• Temperature coefficient: Equal to or lower absolute value than ±50ppm/°C

Two substitute parts meet these criteria: the 9-1625868-3 from TE Connectivity Passive Product (direct substitute with enhanced power rating) and the ERA-6AEB48R7V from Panasonic Electronic Components (upgrade option with automotive qualification).

Parameter Comparison

Engineering Selection Recommendations

9-1625868-3 (TE Connectivity Passive Product): This part provides direct substitution with improved electrical performance. The tolerance is tightened to ±0.1% and power rating is increased to 0.25W, both enhancements over the original specification. Temperature coefficient is improved to ±25ppm/°C. All compliance requirements match: ROHS3 compliant, MSL 1, operating range -55°C to 155°C. Selection is appropriate for applications requiring enhanced precision or higher thermal margin.

ERA-6AEB48R7V (Panasonic Electronic Components): This part matches the original power rating of 0.125W while providing tighter tolerance (±0.1%) and improved temperature coefficient (±25ppm/°C). The component carries AEC-Q200 automotive qualification, indicating enhanced reliability screening and qualification for automotive applications. All compliance requirements are met: ROHS3 compliant, REACH unaffected, MSL 1, operating range -55°C to 155°C. Selection is appropriate for automotive applications or where automotive-grade reliability is required.

Frequently Asked Questions (FAQ)

Q: Can the 9-1625868-3 be used as a direct replacement for the RT0805FRE0748R7L?

A: Yes. The 9-1625868-3 maintains the same 48.7 Ohm resistance value, 0805 package format, and thin film composition. The higher power rating (0.25W vs 0.125W) and tighter tolerance (±0.1% vs ±1%) represent improvements that do not compromise compatibility. Physical dimensions are equivalent (0.079" L x 0.049" W), and all compliance certifications align.

Q: What is the advantage of the ERA-6AEB48R7V over the original RT0805FRE0748R7L?

A: The ERA-6AEB48R7V provides tighter tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C), resulting in improved stability and precision. The component carries AEC-Q200 automotive qualification, indicating enhanced reliability for demanding applications. Power rating and package format remain identical.

Q: Are all three parts physically interchangeable?

A: Yes. All three parts use the 0805 (2012 Metric) package with identical footprint dimensions (0.079" L x 0.049" W). Maximum seated heights are equivalent (0.024" to 0.026"), ensuring compatibility with standard PCB assembly processes and reflow profiles.

Q: Which substitute should be selected for automotive applications?

A: The ERA-6AEB48R7V is qualified to AEC-Q200 automotive standards and is the appropriate selection for automotive applications. The other parts do not carry automotive qualification.

Q: Do all parts meet RoHS and environmental compliance requirements?

A: Yes. All three parts are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity level). The ERA-6AEB48R7V additionally carries REACH unaffected status. All parts are classified under ECCN EAR99 and HTSUS 8533.21.0030.
