RT0402FRE0752R3L Equivalent & Substitute Parts

Part Overview

The RT0402FRE0752R3L is a 52.3 Ohm thin film chip resistor manufactured by YAGEO in the 0402 (1005 Metric) package format. This component is rated at 1/16W (0.063W) with ±1% tolerance and operates across the temperature range of -55°C to 155°C. The part maintains Active product status and is ROHS3 compliant with MSL 1 rating, indicating suitability for standard PCB assembly processes without moisture sensitivity constraints.

Equivalent and substitute parts are identified based on matching the core electrical specifications: 52.3 Ohm resistance value, 0402 package geometry, 1/16W power rating, and compatible operating temperature range. Substitute parts with improved tolerance or enhanced features are available from multiple manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by strict adherence to the following parameters:

• Resistance Value: All substitute parts must be 52.3 Ohms
• Package Format: All substitute parts must be 0402 (1005 Metric)
• Power Rating: All substitute parts must be rated 1/16W (0.063W)
• Composition: All substitute parts must be thin film construction
• Operating Temperature Range: All substitute parts must support -55°C to 155°C minimum
• Termination Count: All substitute parts must have 2 terminations
• Compliance: All substitute parts must maintain ROHS3 compliance

Four substitute parts meet these criteria. Three parts (CPF0402B52R3E1, ERA-2AEB52R3X, RG1005P-52R3-B-T5) offer improved tolerance at ±0.1% compared to the main part's ±1%. One part (RN73C1E52R3BTDF) also provides ±0.1% tolerance with superior temperature coefficient performance.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts maintain ROHS3 compliance and MSL 1 rating, ensuring compatibility with standard PCB assembly processes. Selection between substitutes depends on application-specific requirements:

CPF0402B52R3E1 (TE Connectivity Passive Product, Neohm series) provides ±0.1% tolerance with ±25ppm/°C temperature coefficient and maintains the same 0.35mm maximum seated height as the main part. This option is suitable for general precision applications requiring improved tolerance without automotive qualification.

ERA-2AEB52R3X (Panasonic Electronic Components, ERA-2A series) combines ±0.1% tolerance with AEC-Q200 automotive qualification and ±25ppm/°C temperature coefficient. The 0.40mm maximum seated height accommodates automotive PCB assembly specifications. This part is appropriate for automotive and harsh environment applications.

RG1005P-52R3-B-T5 (Susumu, RG series) offers ±0.1% tolerance, AEC-Q200 automotive qualification, anti-sulfur features, and ±25ppm/°C temperature coefficient. The 0.40mm maximum seated height aligns with automotive assembly requirements. This part is specified for automotive applications requiring sulfur resistance.

RN73C1E52R3BTDF (TE Connectivity Passive Product, Holsworthy series) delivers the tightest temperature coefficient at ±10ppm/°C with ±0.1% tolerance and maintains the 0.35mm maximum seated height. This option is optimal for precision applications requiring superior temperature stability without automotive requirements.

Frequently Asked Questions (FAQ)

Q: Can RT0402FRE0752R3L be directly replaced with any of these substitute parts?

A: Yes. All substitute parts share identical resistance value (52.3 Ohms), package format (0402), power rating (1/16W), composition (thin film), and operating temperature range (-55°C to 155°C). Direct PCB substitution is mechanically and electrically compatible.

Q: What is the primary difference between the main part and substitute parts?

A: The main part RT0402FRE0752R3L specifies ±1% tolerance, while all four substitute parts offer improved ±0.1% tolerance. Additionally, substitute parts feature lower temperature coefficients (±10ppm/°C to ±25ppm/°C versus ±50ppm/°C), providing superior stability across the operating temperature range.

Q: Which substitute part should be selected for automotive applications?

A: ERA-2AEB52R3X and RG1005P-52R3-B-T5 both carry AEC-Q200 automotive qualification. RG1005P-52R3-B-T5 additionally includes anti-sulfur features for enhanced reliability in harsh automotive environments.

Q: Are there height differences between substitute parts?

A: CPF0402B52R3E1 and RN73C1E52R3BTDF maintain 0.35mm maximum seated height, matching the main part. ERA-2AEB52R3X and RG1005P-52R3-B-T5 have 0.40mm maximum seated height. Both heights are within standard 0402 package specifications and compatible with typical PCB assembly processes.

Q: Do all substitute parts maintain the same moisture sensitivity level?

A: Yes. All substitute parts maintain MSL 1 (Unlimited) rating, identical to the main part. No special moisture control measures are required during storage or assembly.

Q: Which substitute part offers the best temperature stability?

A: RN73C1E52R3BTDF provides the lowest temperature coefficient at ±10ppm/°C, compared to ±25ppm/°C for other substitutes and ±50ppm/°C for the main part. This part is optimal for applications requiring minimal resistance drift across temperature variations.
