Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility is determined by three core parameters: resistance value (41.2 kOhms), package format (0402/1005 Metric), and composition (thin film). All identified substitutes maintain these three parameters identically to the main part.

Secondary parameters that differentiate substitutes include tolerance (±0.1%, ±0.5%, or ±1%), temperature coefficient (±25ppm/°C or ±50ppm/°C), packaging format (Tape & Reel or Cut Tape), and special features (automotive AEC-Q200 certification or anti-sulfur treatment). All substitutes operate within the same temperature range (-55°C to 155°C) and maintain ROHS3 compliance and MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

RT0402BRD0741K2L and CPF0402B41K2E1 are suitable for applications requiring ±0.1% tolerance with improved temperature stability (±25ppm/°C). Both parts are active products with ROHS3 compliance and MSL 1 rating. RT0402BRD0741K2L offers YAGEO continuity with alternative packaging. CPF0402B41K2E1 provides TE Connectivity sourcing with equivalent specifications.

RT0402DRE0741K2L maintains YAGEO sourcing with ±0.5% tolerance as an intermediate option between the main part and higher-precision alternatives.

ERA-2AEB4122X is specified for automotive applications requiring AEC-Q200 certification with ±0.1% tolerance and ±25ppm/°C temperature coefficient. This part is active with 24,609 units in stock.

RG1005P-4122-D-T10 is designated for automotive environments with AEC-Q200 rating and anti-sulfur treatment. This part combines ±0.5% tolerance with ±25ppm/°C temperature coefficient and is active in production.

All substitute parts maintain identical resistance value, package format, power rating, operating temperature range, RoHS compliance, and moisture sensitivity level as the main part.

Frequently Asked Questions (FAQ)

Q: Can RT0402BRD0741K2L replace RT0402FRE0741K2L in any application?

A: RT0402BRD0741K2L is electrically compatible as a direct substitute. It provides improved tolerance (±0.1% vs ±1%) and lower temperature coefficient (±25ppm/°C vs ±50ppm/°C). The primary difference is packaging format (Cut Tape & Digi-Reel vs Tape & Reel). Verify packaging compatibility with your assembly process before substitution.

Q: What is the difference between YAGEO RT series and Panasonic ERA-2A series?

A: Both are thin film 0402 resistors with identical resistance and power rating. ERA-2AEB4122X includes automotive AEC-Q200 certification, making it suitable for automotive applications. YAGEO RT0402 series parts do not carry AEC-Q200 rating. Select ERA-2AEB4122X if automotive qualification is required.

Q: Is RG1005P-4122-D-T10 compatible with standard PCB assembly processes?

A: Yes. RG1005P-4122-D-T10 maintains the 0402 (1005 Metric) package format and standard termination configuration. The anti-sulfur treatment is an additional feature that does not affect assembly compatibility. Tape & Reel packaging is standard for automated pick-and-place equipment.

Q: Can I use a ±0.1% tolerance part where ±1% is specified?

A: Yes. A ±0.1% tolerance part exceeds the ±1% specification and is suitable for applications originally designed for ±1% tolerance. The tighter tolerance provides improved circuit performance and stability.

Q: What does MSL 1 rating mean for storage and handling?

A: MSL 1 (Unlimited) indicates unlimited floor life. The component does not require special moisture control during storage or handling. All listed substitute parts maintain MSL 1 rating.
