Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012P-434-B-T5 is determined by the following critical parameters:

Primary Substitution Criteria:

• Resistance value: 430 kOhms
• Tolerance: ±0.1%
• Package: 0805 (2012 Metric)
• Composition: Thin Film
• Temperature Coefficient: ±25ppm/°C
• Operating Temperature Range: -55°C ~ 155°C
• Terminations: 2
• RoHS Compliance: ROHS3

Direct Equivalents maintain identical electrical specifications and power rating (0.125W / 1/8W). These parts are interchangeable without circuit modification.

Similar Substitutes share all critical parameters but differ in power rating (0.25W / 1/4W). These parts provide enhanced power dissipation capability and are suitable for applications where the original 0.125W rating is adequate or where higher power margin is beneficial. Physical dimensions remain compatible with 0805 package footprints.

All identified substitutes maintain AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating, ensuring compatibility with automotive and industrial applications.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalents (Identical Specifications):

ERA-6AEB434V (Panasonic Electronic Components) and RT0805BRD07430KL (YAGEO) are direct equivalents to the RG2012P-434-B-T5. Both parts maintain 0.125W power rating, 430 kOhms resistance, ±0.1% tolerance, and identical electrical characteristics. Both are active production parts with ROHS3 compliance and MSL 1 rating. ERA-6AEB434V carries AEC-Q200 automotive qualification. RT0805BRD07430KL does not specify AEC-Q200 rating in provided data. Selection between these direct equivalents is based on availability, lead time, and supply chain requirements.

Similar Substitute (Enhanced Power Rating):

RNCF0805BTE430K (Stackpole Electronics Inc) is a similar substitute with identical electrical specifications but rated for 0.25W (1/4W) power dissipation. This part is suitable for applications where the original 0.125W rating is adequate or where additional power margin is required. The RNCF0805BTE430K maintains AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating. Physical footprint compatibility is maintained within 0805 package specifications. Maximum seated height increases to 0.026" (0.65mm) compared to the original 0.020" (0.50mm), which requires verification for applications with height constraints.

All substitute parts are active production components with current inventory availability.

Frequently Asked Questions (FAQ)

Q: Can ERA-6AEB434V be used as a direct replacement for RG2012P-434-B-T5?

A: Yes. ERA-6AEB434V is a direct equivalent with identical resistance (430 kOhms), tolerance (±0.1%), power rating (0.125W), package (0805), and operating temperature range (-55°C ~ 155°C). Both parts are ROHS3 compliant with MSL 1 rating and AEC-Q200 automotive qualification.

Q: What is the difference between RT0805BRD07430KL and the main part RG2012P-434-B-T5?

A: RT0805BRD07430KL is a direct equivalent in terms of electrical specifications and power rating. The primary difference is manufacturer (YAGEO versus Susumu). AEC-Q200 rating is not specified for the YAGEO part in available data. Both maintain identical 0.125W power rating and 0805 package configuration.

Q: Can RNCF0805BTE430K replace RG2012P-434-B-T5 in all applications?

A: RNCF0805BTE430K is a similar substitute with identical electrical specifications but higher power rating (0.25W versus 0.125W). This part is suitable for applications where the original 0.125W rating is adequate. The increased seated height (0.026" versus 0.020") requires verification for applications with strict height constraints or high-density PCB layouts.

Q: Are all substitute parts automotive-qualified?

A: ERA-6AEB434V and RNCF0805BTE430K carry AEC-Q200 automotive qualification. RT0805BRD07430KL does not specify AEC-Q200 rating in provided specifications. For automotive applications requiring AEC-Q200 compliance, ERA-6AEB434V and RNCF0805BTE430K are confirmed suitable.

Q: Do all parts meet RoHS compliance requirements?

A: Yes. All listed parts (RG2012P-434-B-T5, ERA-6AEB434V, RT0805BRD07430KL, and RNCF0805BTE430K) are ROHS3 compliant and suitable for applications requiring RoHS compliance.

Q: What is the significance of the ±25ppm/°C temperature coefficient?

A: The ±25ppm/°C temperature coefficient indicates the resistance change per degree Celsius across the operating temperature range (-55°C ~ 155°C). All listed parts maintain this identical specification, ensuring consistent performance across temperature extremes in automotive and industrial environments.

Q: Are there any physical compatibility concerns when substituting parts?

A: All parts use 0805 (2012 Metric) package with identical length (0.079") and width (0.049"). Seated height varies slightly: RG2012P-434-B-T5 (0.020"), ERA-6AEB434V (0.024"), RT0805BRD07430KL (0.024"), and RNCF0805BTE430K (0.026"). For applications with height constraints below 0.024", only the original RG2012P-434-B-T5 is suitable. All parts are compatible with standard 0805 PCB footprints.

Q: What is MSL 1 rating and why is it important?

A: MSL (Moisture Sensitivity Level) 1 indicates unlimited shelf life without moisture exposure requirements. All listed parts carry MSL 1 rating, eliminating moisture-related handling and storage constraints common to higher MSL components.
