RNCF0805DTC430K Equivalent & Substitute Parts

Part Overview

The RNCF0805DTC430K is a 430 kOhms ±0.5% thin film chip resistor in 0805 (2012 Metric) package rated for 0.25W (1/4W) power dissipation. This component is manufactured by Stackpole Electronics Inc and meets AEC-Q200 automotive qualification standards. The part is active in production with full RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical specifications and mechanical compatibility are maintained across the same package footprint and tolerance class.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RNCF0805DTC430K is determined by the following critical parameters:

Electrical Equivalence Requirements:

• Resistance value: 430 kOhms (exact match required)
• Tolerance: ±0.5% (exact match required)
• Temperature coefficient: ±50ppm/°C (exact match required)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)

Mechanical Compatibility Requirements:

• Package / Case: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Number of terminations: 2 (exact match required)

Compliance Requirements:

• RoHS3 Compliant status (required)
• Moisture Sensitivity Level 1 (required)

The RT0805DRE07430KL manufactured by YAGEO meets all electrical and mechanical compatibility criteria. The primary distinction is the power rating differential (0.125W vs. 0.25W), which does not preclude substitution in applications where the lower power rating is sufficient for the circuit design requirements.

Parameter Comparison

Engineering Selection Recommendations

Both the RNCF0805DTC430K and RT0805DRE07430KL are active production components with full RoHS3 compliance and MSL 1 rating. Selection between these parts is determined by power dissipation requirements in the specific application circuit.

The RNCF0805DTC430K is specified for 0.25W continuous power dissipation and includes AEC-Q200 automotive qualification. This part is suitable for automotive applications and general-purpose circuits requiring the higher power rating.

The RT0805DRE07430KL is specified for 0.125W continuous power dissipation without automotive qualification. This part is suitable for applications where power dissipation does not exceed 0.125W and automotive qualification is not required.

Both parts share identical electrical characteristics (resistance, tolerance, temperature coefficient, operating temperature range) and mechanical compatibility (0805 package, thin film composition, identical footprint dimensions). The height differential (0.65mm vs. 0.60mm) is within standard PCB assembly tolerances.

Frequently Asked Questions (FAQ)

Q: Can RT0805DRE07430KL replace RNCF0805DTC430K in all applications?

A: Substitution is valid only when the circuit power dissipation at the 430 kOhms resistor does not exceed 0.125W. If the application requires 0.25W power handling capability, the RNCF0805DTC430K must be used. If automotive AEC-Q200 qualification is a design requirement, the RNCF0805DTC430K is the specified part.

Q: Are the physical dimensions compatible for PCB assembly?

A: Both parts use the 0805 (2012 Metric) package with identical length (0.079" / 2.00mm) and width (0.049" / 1.25mm). The seated height difference (0.026" vs. 0.024") is within standard PCB assembly tolerances and does not affect footprint compatibility or reflow soldering processes.

Q: What are the key electrical parameters that must match for substitution?

A: Resistance value (430 kOhms), tolerance (±0.5%), temperature coefficient (±50ppm/°C), and operating temperature range (-55°C ~ 155°C) must be identical. Both parts meet these requirements.

Q: Does the absence of AEC-Q200 rating on the YAGEO part affect substitution eligibility?

A: AEC-Q200 qualification is specific to automotive applications. If the application is non-automotive and does not require automotive qualification, the absence of this rating does not preclude substitution. If automotive qualification is a design requirement, only the RNCF0805DTC430K is acceptable.

Q: Are both parts RoHS3 compliant?

A: Yes, both the RNCF0805DTC430K and RT0805DRE07430KL are ROHS3 compliant with MSL 1 (unlimited moisture sensitivity) rating.
