Key Parameters

Substitute Part Grouping Explanation

Substitution of the RG2012P-473-W-T1 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 47 kOhms (exact match required)
• Tolerance: ±0.05% (exact match required)
• Power rating: 0.125W / 1/8W (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package type: 0805 (2012 Metric) (exact match required)
• Composition: Thin Film (exact match required)

Compliance & Certification:

• AEC-Q200 automotive qualification (required for automotive applications)
• RoHS3 compliance (required for regulatory conformance)
• Moisture Sensitivity Level 1 (required for storage and handling compatibility)

Substitute parts are grouped into two categories:

Direct Substitutes (Same Manufacturer - Susumu):

• RG2012P-473-W-T5: Identical electrical and mechanical specifications; differs only in packaging format (Tape & Reel vs. bulk) and product status (Active vs. Obsolete)
• RG2012N-473-W-T5: Enhanced temperature coefficient (±10ppm/°C vs. ±25ppm/°C); maintains all other specifications; Active status

Cross-Manufacturer Substitutes (Panasonic & YAGEO):

• ERA-6ARW473V (Panasonic): Meets all electrical specifications; enhanced temperature coefficient (±10ppm/°C); slight height variation (0.024" vs. 0.020"); Active status
• RT0805WRB0747KL (YAGEO): Meets all electrical specifications; enhanced temperature coefficient (±10ppm/°C); slight height variation (0.024" vs. 0.020"); no automotive feature designation; Active status

Parameter Comparison

Engineering Selection Recommendations

For Automotive AEC-Q200 Applications:

RG2012P-473-W-T5 and RG2012N-473-W-T5 are the primary substitutes for the obsolete RG2012P-473-W-T1. Both maintain Susumu manufacturer continuity and full AEC-Q200 compliance. RG2012P-473-W-T5 provides direct electrical equivalence with identical temperature coefficient (±25ppm/°C). RG2012N-473-W-T5 offers enhanced temperature stability (±10ppm/°C) while maintaining all other specifications and is recommended for applications requiring tighter tolerance performance over extended temperature ranges.

ERA-6ARW473V (Panasonic) is a qualified cross-manufacturer substitute with AEC-Q200 certification and enhanced temperature coefficient (±10ppm/°C). The seated height increases from 0.020" to 0.024", which must be evaluated for PCB layout clearance constraints. This component is suitable for automotive applications requiring Panasonic supply chain qualification.

RT0805WRB0747KL (YAGEO) meets all electrical specifications and offers enhanced temperature coefficient (±10ppm/°C). However, this component lacks AEC-Q200 automotive qualification and is not designated for automotive applications. The seated height is 0.024" (0.60mm). This substitute is suitable only for non-automotive applications or where automotive qualification is not required.

Packaging Considerations:

RG2012P-473-W-T1 is supplied in bulk packaging (product status: Obsolete). RG2012P-473-W-T5 and RG2012N-473-W-T5 are supplied in Tape & Reel format (product status: Active), which is standard for current production. ERA-6ARW473V and RT0805WRB0747KL are also supplied in Tape & Reel format.

Frequently Asked Questions (FAQ)

Q: Can RG2012P-473-W-T5 be used as a direct replacement for RG2012P-473-W-T1?

A: Yes. RG2012P-473-W-T5 is electrically and mechanically identical to RG2012P-473-W-T1. The primary difference is product status (Active vs. Obsolete) and packaging format (Tape & Reel vs. bulk). Both components share identical resistance (47 kOhms), tolerance (±0.05%), power rating (0.125W), temperature coefficient (±25ppm/°C), and AEC-Q200 qualification.

Q: What is the difference between RG2012P-473-W-T5 and RG2012N-473-W-T5?

A: Both components are manufactured by Susumu and meet all core specifications. The key difference is temperature coefficient: RG2012P-473-W-T5 has ±25ppm/°C, while RG2012N-473-W-T5 has ±10ppm/°C. RG2012N-473-W-T5 provides enhanced temperature stability and is recommended for applications requiring tighter tolerance performance across the full operating temperature range (-55°C ~ 155°C).

Q: Can ERA-6ARW473V be used in automotive applications?

A: Yes. ERA-6ARW473V is manufactured by Panasonic and carries AEC-Q200 automotive qualification. It meets all electrical specifications (47 kOhms ±0.05%, 0.125W, ±10ppm/°C temperature coefficient). The seated height is 0.024" (0.60mm) compared to 0.020" (0.50mm) for the original part. PCB layout clearance must be evaluated before substitution.

Q: Why is RT0805WRB0747KL not recommended for automotive applications?

A: RT0805WRB0747KL is manufactured by YAGEO and does not carry AEC-Q200 automotive qualification. While it meets all electrical specifications (47 kOhms ±0.05%, 0.125W, ±10ppm/°C), it is not qualified for automotive use. This component is suitable only for non-automotive applications or where automotive qualification is not a requirement.

Q: Does the height difference between substitute parts affect PCB compatibility?

A: The original RG2012P-473-W-T1 has a maximum seated height of 0.020" (0.50mm). RG2012P-473-W-T5 and RG2012N-473-W-T5 maintain this height. ERA-6ARW473V and RT0805WRB0747KL have a maximum seated height of 0.024" (0.60mm). This 0.004" (0.10mm) increase must be evaluated against PCB layout constraints, including clearance to adjacent components and conformal coating requirements.

Q: Are all substitute parts RoHS3 compliant?

A: Yes. All substitute parts listed (RG2012P-473-W-T5, RG2012N-473-W-T5, ERA-6ARW473V, and RT0805WRB0747KL) are RoHS3 compliant and maintain Moisture Sensitivity Level 1 (Unlimited), matching the original RG2012P-473-W-T1 specifications.

Q: What is the inventory status of substitute parts?

A: RG2012P-473-W-T5 has 830 pieces in stock. RG2012N-473-W-T5 has 904 pieces in stock. ERA-6ARW473V has 1904 pieces in stock. RT0805WRB0747KL has 1134 pieces in stock. All substitute parts are currently in active production status.
