Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RG2012N-433-B-T5 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Resistance value: 43 kOhms
• Package format: 0805 (2012 Metric)
• Power rating: 0.125W (1/8W)
• Composition: Thin Film
• Temperature coefficient: ±10ppm/°C
• Operating temperature range: -55°C ~ 155°C
• Automotive qualification: AEC-Q200
• RoHS compliance: ROHS3
• Moisture sensitivity: MSL 1

Allowable Variation:

• Tolerance: ±0.1% or tighter (±0.05% qualifies as upgrade)
• Physical height: Seated maximum up to 0.024" (0.60mm) acceptable

The identified substitute parts ERA-6ARB433V and ERA-6ARW433V satisfy all mandatory parameters. ERA-6ARW433V provides enhanced tolerance specification (±0.05%) while maintaining all other electrical and mechanical requirements.

Parameter Comparison

Engineering Selection Recommendations

Direct Equivalent (ERA-6ARB433V): The ERA-6ARB433V manufactured by Panasonic Electronic Components provides direct functional equivalence to the RG2012N-433-B-T5. Both components share identical electrical specifications, package format, and automotive qualification. This substitute is suitable for applications requiring equivalent performance without tolerance enhancement. Both parts maintain active production status and full ROHS3 compliance.

Enhanced Tolerance Alternative (ERA-6ARW433V): The ERA-6ARW433V offers improved tolerance specification at ±0.05% compared to the ±0.1% of the primary part. This component maintains all other electrical and mechanical parameters while providing tighter resistance accuracy. Selection of ERA-6ARW433V is appropriate for applications with stricter tolerance requirements or where enhanced precision contributes to circuit performance. Physical height increases from 0.50mm to 0.60mm maximum seated height; board layout clearance must be verified.

Both substitute parts carry AEC-Q200 automotive qualification, ROHS3 compliance, and MSL 1 rating, ensuring compatibility with automotive and industrial applications requiring these certifications.

Frequently Asked Questions (FAQ)

Q: Can ERA-6ARB433V be used as a direct replacement for RG2012N-433-B-T5?

A: Yes. ERA-6ARB433V meets all electrical and mechanical specifications of the RG2012N-433-B-T5, including 43 kOhms resistance, ±0.1% tolerance, 0.125W power rating, 0805 package format, ±10ppm/°C temperature coefficient, and AEC-Q200 automotive qualification. Both components are thin film resistors with identical operating temperature range and compliance certifications.

Q: What is the difference between ERA-6ARB433V and ERA-6ARW433V?

A: The primary difference is tolerance specification. ERA-6ARB433V provides ±0.1% tolerance matching the original RG2012N-433-B-T5, while ERA-6ARW433V offers enhanced ±0.05% tolerance. Both share identical resistance value, power rating, package format, temperature coefficient, and automotive qualification. Physical seated height increases from 0.50mm (RG2012N-433-B-T5) to 0.60mm maximum for both Panasonic alternatives.

Q: Are there any package or footprint compatibility concerns?

A: All three components use the 0805 (2012 Metric) package format with identical land pattern dimensions of 0.079" L x 0.049" W (2.00mm x 1.25mm). The seated height difference between the Susumu part (0.50mm maximum) and Panasonic parts (0.60mm maximum) is 0.10mm. Board layout clearance must be verified for applications with height-constrained assembly requirements.

Q: Do all substitute parts maintain automotive qualification?

A: Yes. RG2012N-433-B-T5, ERA-6ARB433V, and ERA-6ARW433V all carry AEC-Q200 automotive qualification. All three components are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating, suitable for automotive and industrial applications requiring these certifications.

Q: Can ERA-6ARW433V be used in place of RG2012N-433-B-T5 in all applications?

A: ERA-6ARW433V is functionally compatible with RG2012N-433-B-T5 for all applications. The ±0.05% tolerance of ERA-6ARW433V is tighter than the ±0.1% requirement, providing equal or superior performance. Physical height increase from 0.50mm to 0.60mm maximum must be evaluated for board layout constraints.

Q: What is the temperature coefficient significance for these resistors?

A: All three components share an identical temperature coefficient of ±10ppm/°C, ensuring consistent resistance stability across the operating temperature range of -55°C to 155°C. This parameter is critical for precision analog circuits and does not differentiate between the main part and substitutes.
