Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012N-47R5-C-T5 is determined by the following critical parameters that must remain constant or improve:

Mandatory Compatibility Parameters:

• Resistance value: 47.5 Ohms (exact match required)
• Package type: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)
• Temperature Coefficient: ±10ppm/°C (exact match required)
• Automotive Rating: AEC-Q200 (exact match required)
• Anti-Sulfur feature: Required (exact match required)

Allowable Upgrade Parameters:

• Tolerance: Can be equal or tighter (±0.25% or better)
• Power Rating: Can be equal or higher (0.125W or greater)
• Operating Temperature Range: Can be equal or extended
• Product Status: Active substitutes preferred over obsolete

All substitute parts listed maintain identical mechanical dimensions (0.079" L x 0.049" W / 2.00mm x 1.25mm) and electrical characteristics within the specified parameters. Substitutes are grouped by tolerance specification, representing performance upgrades while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Susumu RG Series):

The RG2012N-47R5-B-T5, RG2012N-47R5-W-T1, and RG2012N-47R5-W-T5 are direct Susumu replacements maintaining identical mechanical and thermal specifications. All three are active products with ROHS3 compliance and AEC-Q200 automotive qualification. Selection between these three Susumu options depends on tolerance requirements:

• RG2012N-47R5-B-T5 provides ±0.1% tolerance, representing a one-step tolerance improvement over the main part while maintaining 0.125W power rating and identical operating temperature range.
• RG2012N-47R5-W-T1 and RG2012N-47R5-W-T5 both offer ±0.05% tolerance, the tightest specification available, with identical power and temperature characteristics. These differ only in packaging configuration (T1 versus T5 tape specifications).

Alternative Substitute (Vishay Dale TNPW Series):

The TNPW080547R5BYEA from Vishay Dale provides cross-manufacturer compatibility with identical resistance, tolerance matching the RG2012N-47R5-B-T5 at ±0.1%, and enhanced power rating of 0.26W (double the main part). This component extends the operating temperature range to -55°C ~ 175°C and includes moisture-resistant construction. The TNPW series is suitable for applications requiring higher thermal headroom or extended temperature operation while maintaining AEC-Q200 qualification and ROHS3 compliance.

All substitute parts are active products with confirmed inventory availability and maintain full electrical and mechanical compatibility with the obsolete RG2012N-47R5-C-T5.

Frequently Asked Questions (FAQ)

Q: Can RG2012N-47R5-B-T5 be used as a direct replacement for RG2012N-47R5-C-T5?

A: Yes. The RG2012N-47R5-B-T5 maintains identical resistance (47.5 Ohms), package (0805), power rating (0.125W), temperature coefficient (±10ppm/°C), operating temperature range (-55°C ~ 155°C), and automotive qualification (AEC-Q200). The tolerance is tighter at ±0.1% compared to ±0.25%, which represents an improvement in accuracy without affecting compatibility.

Q: What is the difference between RG2012N-47R5-W-T1 and RG2012N-47R5-W-T5?

A: Both parts are electrically and mechanically identical with 47.5 Ohms ±0.05% tolerance, 0.125W power rating, and 0805 package. The difference lies in tape configuration: T1 and T5 designations refer to different tape specifications for automated assembly. Selection depends on your manufacturing equipment compatibility.

Q: Why does TNPW080547R5BYEA have a higher power rating (0.26W) in the same 0805 package?

A: The TNPW080547R5BYEA achieves higher power dissipation through enhanced thermal design and material composition while maintaining the same external dimensions. This provides additional thermal margin for applications with higher power requirements. The component remains mechanically compatible with 0805 footprints.

Q: Are all substitute parts AEC-Q200 qualified?

A: Yes. All listed substitute parts (RG2012N-47R5-B-T5, RG2012N-47R5-W-T1, RG2012N-47R5-W-T5, and TNPW080547R5BYEA) carry AEC-Q200 automotive qualification, meeting the same reliability standards as the main part.

Q: Can I use TNPW080547R5BYEA in place of the Susumu parts?

A: Yes. The TNPW080547R5BYEA is electrically and mechanically compatible with all Susumu RG2012N-47R5 variants. It provides equivalent or superior performance with ±0.1% tolerance, higher power rating (0.26W), extended temperature range (-55°C ~ 175°C), and moisture-resistant construction. Cross-manufacturer substitution is valid for applications where these enhanced specifications are acceptable.

Q: What does the obsolete status of RG2012N-47R5-C-T5 mean for my design?

A: Obsolete status indicates the part is no longer manufactured by Susumu. Active substitute parts listed in this reference maintain full compatibility and are currently in production with confirmed inventory availability. Transition to an active substitute part is recommended for new designs and ongoing production requirements.

Q: Are all substitute parts ROHS3 compliant?

A: Yes. All substitute parts listed are ROHS3 compliant, matching the environmental compliance of the main part. All components also maintain Moisture Sensitivity Level 1 (Unlimited) rating.
