RT0603FRE0752R3L Equivalent & Substitute Parts

Part Overview

The RT0603FRE0752R3L is a 52.3 Ohm ±1% thin film chip resistor in 0603 (1608 Metric) package rated at 0.1W (1/10W) power dissipation. Manufactured by YAGEO under the RT series, this component is actively produced and ROHS3 compliant. Substitute parts are identified when equivalent resistance values, package dimensions, and power ratings align within acceptable electrical and mechanical tolerances, enabling direct replacement in circuit applications where the original part becomes unavailable or when upgraded performance characteristics are required.

Substitute Part Grouping Explanation

Substitute parts for the RT0603FRE0752R3L are qualified based on the following criteria:

Critical Parameters (Must Match):

• Resistance value: 52.3 Ohms
• Package / Case: 0603 (1608 Metric)
• Composition: Thin Film
• Operating temperature range: -55°C ~ 155°C minimum
• RoHS3 compliance

Allowable Variations:

• Tolerance: ±1% or tighter (±0.1% acceptable as upgrade)
• Temperature coefficient: ±50ppm/°C or better (±25ppm/°C acceptable as upgrade)
• Power rating: 0.1W minimum (0.167W acceptable as upgrade)

Three substitute parts meet these criteria: RT0603BRD0752R3L (YAGEO, tighter tolerance), ERA-3AEB52R3V (Panasonic, automotive-grade), and RP73PF1J52R3BTDF (TE Connectivity, higher power rating).

Parameter Comparison

Engineering Selection Recommendations

RT0603BRD0752R3L (YAGEO): Direct substitute with improved tolerance specification (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C). Same manufacturer, package, and power rating. Suitable for applications requiring tighter resistance accuracy without design modification.

ERA-3AEB52R3V (Panasonic Electronic Components): Qualified substitute with automotive AEC-Q200 certification. Offers ±0.1% tolerance and ±25ppm/°C temperature coefficient. Appropriate for automotive and high-reliability applications where AEC-Q200 qualification is required or beneficial.

RP73PF1J52R3BTDF (TE Connectivity Passive Product): Qualified substitute with higher power rating (0.167W vs 0.1W). Provides ±0.1% tolerance and ±25ppm/°C temperature coefficient. Suitable for applications where increased thermal headroom or higher power dissipation capability is advantageous. Dimensions vary slightly (0.061" L vs 0.063" L); verify PCB layout compatibility.

All three substitutes maintain ROHS3 compliance, MSL 1 rating, and the required operating temperature range.

Frequently Asked Questions (FAQ)

Q: Can RT0603BRD0752R3L replace RT0603FRE0752R3L directly? A: Yes. Both parts share identical resistance (52.3 Ohms), package (0603), power rating (0.1W), and operating temperature range (-55°C ~ 155°C). RT0603BRD0752R3L offers superior tolerance (±0.1%) and temperature coefficient (±25ppm/°C) with no design changes required.

Q: What is the difference between ERA-3AEB52R3V and the YAGEO substitutes? A: ERA-3AEB52R3V is manufactured by Panasonic and carries AEC-Q200 automotive qualification. Electrical specifications (52.3 Ohms, ±0.1%, 0.1W, 0603 package) are equivalent. Select this part for automotive applications or when AEC-Q200 certification is specified.

Q: Why does RP73PF1J52R3BTDF have a different power rating? A: RP73PF1J52R3BTDF is rated at 0.167W (1/6W) compared to 0.1W (1/10W) for the original part. This higher power rating provides additional thermal margin in high-dissipation circuits. The 0603 package dimensions are functionally equivalent; verify PCB layout for the slight length variation (0.061" vs 0.063").

Q: Are all substitutes ROHS3 compliant? A: Yes. RT0603BRD0752R3L, ERA-3AEB52R3V, and RP73PF1J52R3BTDF are all ROHS3 compliant with MSL 1 (Unlimited) moisture sensitivity rating.

Q: Can I use these substitutes interchangeably in production? A: All three substitutes are electrically and mechanically compatible with the RT0603FRE0752R3L within the specified parameters. Selection depends on application requirements: standard industrial use (RT0603BRD0752R3L), automotive applications (ERA-3AEB52R3V), or higher power dissipation needs (RP73PF1J52R3BTDF).
