Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the RT0603CRE0748R7L are qualified based on the following criteria:

Mandatory Matching Parameters:

• Resistance value: 48.7 Ohms
• Package type: 0603 (1608 Metric)
• Composition: Thin Film
• Number of terminations: 2
• Operating temperature range: -55°C to 155°C minimum
• RoHS3 compliance

Allowable Variations:

• Tolerance: Equal to or tighter than ±0.25%
• Power rating: Equal to or greater than 0.1W
• Temperature coefficient: Equal to or lower absolute value than ±50ppm/°C
• Moisture sensitivity level: 1 (Unlimited)

Two substitute parts meet these criteria: ERA-3AEB48R7V (Panasonic) and RP73PF1J48R7BTDF (TE Connectivity).

Parameter Comparison

Engineering Selection Recommendations

ERA-3AEB48R7V (Panasonic Electronic Components) provides direct substitution with improved tolerance (±0.1% vs ±0.25%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C). This part carries AEC-Q200 automotive qualification, suitable for applications requiring automotive-grade reliability. Identical power rating and package dimensions ensure drop-in compatibility.

RP73PF1J48R7BTDF (TE Connectivity Passive Product) offers higher power rating (0.167W vs 0.1W) with improved tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C). Slight dimensional variation in length (1.55mm vs 1.60mm) remains within 0603 package specification. This part is suitable for applications with higher thermal dissipation requirements.

Both substitutes maintain ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1), ensuring compatibility with standard manufacturing and storage conditions.

Frequently Asked Questions (FAQ)

Q: Can ERA-3AEB48R7V replace RT0603CRE0748R7L in any application?

A: Yes. ERA-3AEB48R7V meets all mandatory electrical and mechanical parameters. The tighter tolerance (±0.1%) and lower temperature coefficient (±25ppm/°C) represent improvements over the original specification. AEC-Q200 qualification provides additional reliability assurance for automotive and high-reliability applications.

Q: What is the key difference between RP73PF1J48R7BTDF and the original part?

A: RP73PF1J48R7BTDF has a higher power rating (0.167W vs 0.1W) and improved tolerance (±0.1% vs ±0.25%). Length dimension is 1.55mm versus 1.60mm for the original, both within 0603 package tolerance. This part is suitable for circuits requiring higher power dissipation capability.

Q: Are all three parts pin-compatible?

A: Yes. All three parts have identical 2-termination configurations in 0603 (1608 Metric) package with matching height specifications (0.022" maximum seated height). PCB footprints are interchangeable.

Q: Which substitute should I select for high-precision applications?

A: Both ERA-3AEB48R7V and RP73PF1J48R7BTDF offer ±0.1% tolerance, superior to the original ±0.25%. ERA-3AEB48R7V additionally features lower temperature coefficient (±25ppm/°C), providing better stability across the -55°C to 155°C operating range.

Q: Are there any compliance differences between the three parts?

A: All three parts are ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating. ERA-3AEB48R7V carries additional AEC-Q200 automotive qualification. REACH status is unaffected for RT0603CRE0748R7L and ERA-3AEB48R7V; RP73PF1J48R7BTDF shows vendor undefined REACH status.
