Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012P-5900-W-T1 is determined by the following critical parameters: resistance value (590 Ohms), tolerance specification (±0.05% or tighter), power rating (0.125W minimum), package type (0805), composition (thin film), operating temperature range (-55°C to 155°C), and automotive qualification (AEC-Q200). Substitute parts are grouped into two categories:

Direct Substitutes (Packaging Variants): Parts maintaining identical electrical specifications and Susumu RG series lineage with differences limited to packaging format (bulk versus tape & reel) or temperature coefficient improvements within the same tolerance class.

Upgrade Substitutes (Enhanced Performance): Susumu RG series parts offering improved temperature coefficient performance (±10ppm/°C or ±5ppm/°C) or tighter tolerance (±0.02%) while maintaining all other critical parameters.

Similar Substitutes (Cross-Manufacturer): Panasonic ERA-6A series components meeting the same resistance, package, power rating, and AEC-Q200 qualification, with tolerance specification of ±0.1% (wider than original but within acceptable range for many applications).

Parameter Comparison

Engineering Selection Recommendations

Primary Recommendation: RG2012V-5900-W-T1 (Susumu) is the preferred direct substitute. This part maintains identical electrical specifications to the original RG2012P-5900-W-T1 while offering improved temperature coefficient performance (±5ppm/°C versus ±25ppm/°C). The component is active in production, ROHS3 compliant, AEC-Q200 qualified, and available in tape & reel packaging suitable for automated assembly. Inventory availability is 938 pieces.

Secondary Recommendation: RG2012P-5900-W-T5 (Susumu) provides direct electrical equivalence with identical tolerance and temperature coefficient specifications. This part differs only in packaging format (tape & reel versus bulk), making it suitable for high-volume production environments. Product status is active with 751 pieces in stock.

Enhanced Performance Option: RG2012N-5900-W-T1 (Susumu) offers improved temperature coefficient (±10ppm/°C) while maintaining the ±0.05% tolerance specification. This upgrade is applicable for designs requiring enhanced thermal stability. Product status is active with 800 pieces available.

Premium Upgrade Option: RG2012V-5900-P-T1 (Susumu) provides the tightest tolerance specification (±0.02%) combined with superior temperature coefficient (±5ppm/°C). This component is suitable for precision measurement and calibration circuits. Product status is active with 830 pieces in inventory.

Cross-Manufacturer Alternative: ERA-6AEB5900V (Panasonic) is a functionally compatible substitute meeting identical resistance, package, power rating, and AEC-Q200 automotive qualification. The tolerance specification is ±0.1% (wider than the original ±0.05%), and temperature coefficient is ±25ppm/°C. This part is active in production with substantial inventory (12,241 pieces), providing supply chain redundancy. Height specification differs slightly (0.024" maximum versus 0.020" maximum), which may require verification in space-constrained applications.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-5900-W-T5 be used as a direct replacement for RG2012P-5900-W-T1?

A: Yes. RG2012P-5900-W-T5 is electrically and mechanically identical to RG2012P-5900-W-T1. The only difference is packaging format: RG2012P-5900-W-T5 is supplied in tape & reel format while RG2012P-5900-W-T1 was supplied in bulk. Both parts share identical resistance (590 Ohms), tolerance (±0.05%), power rating (0.125W), temperature coefficient (±25ppm/°C), and package dimensions (0805).

Q: What is the difference between RG2012V and RG2012N series parts?

A: The RG2012V series offers superior temperature coefficient performance (±5ppm/°C) compared to the RG2012N series (±10ppm/°C). Both maintain the same resistance value, tolerance, power rating, and package type. Selection between these series depends on thermal stability requirements of the application.

Q: Is ERA-6AEB5900V compatible with the original RG2012P-5900-W-T1?

A: ERA-6AEB5900V is functionally compatible for most applications. Both parts share identical resistance (590 Ohms), power rating (0.125W), package type (0805), operating temperature range (-55°C to 155°C), and AEC-Q200 automotive qualification. The tolerance specification differs (±0.1% for ERA-6AEB5900V versus ±0.05% for RG2012P-5900-W-T1), and maximum seated height is 0.024" versus 0.020". Verify tolerance and height specifications against circuit requirements before substitution.

Q: What does the temperature coefficient specification mean for component selection?

A: Temperature coefficient indicates the resistance change per degree Celsius across the operating temperature range. A lower temperature coefficient (±5ppm/°C) indicates greater stability across temperature variations compared to a higher coefficient (±25ppm/°C). Applications requiring precision at varying temperatures benefit from lower temperature coefficient specifications.

Q: Are all substitute parts ROHS3 compliant and AEC-Q200 qualified?

A: Yes. All substitute parts listed (RG2012P-5900-W-T5, RG2012N-5900-W-T1, RG2012V-5900-P-T1, RG2012V-5900-W-T1, RG2012V-5900-W-T5, and ERA-6AEB5900V) are ROHS3 compliant and AEC-Q200 qualified, meeting automotive reliability standards and environmental compliance requirements.

Q: What is the significance of MSL 1 (Unlimited) moisture sensitivity level?

A: MSL 1 indicates the component has unlimited shelf life and requires no special moisture control during storage or handling. This classification simplifies inventory management and eliminates the need for desiccant packaging or baking procedures prior to assembly.

Q: Can RG2012V-5900-P-T1 be used in place of RG2012P-5900-W-T1?

A: Yes. RG2012V-5900-P-T1 is a compatible upgrade offering tighter tolerance (±0.02% versus ±0.05%) and superior temperature coefficient (±5ppm/°C versus ±25ppm/°C). All other parameters including resistance, power rating, package, and operating temperature range are identical. This substitution is suitable for applications requiring enhanced precision and thermal stability.
