RG1608P-473-W-T5 Equivalent & Substitute Parts

Part Overview

The RG1608P-473-W-T5 is a 47 kOhms ±0.05% thin film chip resistor manufactured by Susumu in 0603 (1608 Metric) package format. This component is rated for 0.1W (1/10W) power dissipation and features anti-sulfur coating with automotive AEC-Q200 qualification. The part is actively produced and available in high volume inventory. Substitute parts are identified when equivalent electrical and mechanical specifications are required for design flexibility, supply chain continuity, or inventory optimization.

Substitute Part Grouping Explanation

Substitution of the RG1608P-473-W-T5 is determined by strict equivalence across the following critical parameters:

Electrical Specifications:

• Resistance value: 47 kOhms (exact match required)
• Tolerance: ±0.05% (exact match required)
• Power rating: 0.1W minimum (equal or higher acceptable)
• Composition: Thin film (required for tolerance specification)

Mechanical Specifications:

• Package format: 0603 (1608 Metric) (exact match required)
• Termination count: 2 (exact match required)
• Physical dimensions: 0.063" L x 0.031" W (exact match required)

Compliance & Ratings:

• Automotive qualification: AEC-Q200 (required for automotive applications)
• Operating temperature range: -55°C ~ 155°C (minimum requirement)
• RoHS3 compliance (required)
• Moisture sensitivity level: 1 (Unlimited) (acceptable at equal or lower MSL)

The ERA-3ARW473V manufactured by Panasonic Electronic Components meets all substitution criteria and is classified as an equivalent part.

Parameter Comparison

Engineering Selection Recommendations

Both the RG1608P-473-W-T5 and ERA-3ARW473V are active production components with full AEC-Q200 automotive qualification and ROHS3 compliance. Selection between these parts is based on the following engineering considerations:

RG1608P-473-W-T5 (Susumu):

• Anti-sulfur coating feature provides enhanced environmental protection
• Temperature coefficient of ±25ppm/°C
• Maximum seated height of 0.020" (0.50mm)
• Suitable for applications requiring anti-sulfur protection in corrosive environments

ERA-3ARW473V (Panasonic):

• Superior temperature coefficient of ±10ppm/°C provides tighter performance stability across temperature extremes
• Maximum seated height of 0.022" (0.55mm)
• Suitable for applications requiring enhanced temperature stability
• Higher inventory availability (1142 pcs vs. 955 pcs)

Both parts satisfy identical electrical specifications, mechanical package requirements, and automotive compliance standards. Selection should be based on application-specific requirements for environmental protection (anti-sulfur) or temperature coefficient performance, and supply chain availability.

Frequently Asked Questions (FAQ)

Q: Can ERA-3ARW473V be used as a direct replacement for RG1608P-473-W-T5?

A: Yes. Both parts share identical resistance (47 kOhms), tolerance (±0.05%), power rating (0.1W), package format (0603), operating temperature range (-55°C ~ 155°C), and AEC-Q200 automotive qualification. The physical dimensions and termination count are equivalent. The ERA-3ARW473V has a slightly higher seated height (0.022" vs. 0.020") and superior temperature coefficient (±10ppm/°C vs. ±25ppm/°C).

Q: What is the significance of the temperature coefficient difference?

A: The RG1608P-473-W-T5 has a temperature coefficient of ±25ppm/°C, while the ERA-3ARW473V has ±10ppm/°C. This means the ERA-3ARW473V exhibits smaller resistance value changes across the -55°C to 155°C operating range. For applications requiring tight tolerance maintenance across temperature extremes, the ERA-3ARW473V provides superior stability.

Q: Does the anti-sulfur coating on the RG1608P-473-W-T5 affect substitution?

A: The anti-sulfur coating is a feature of the RG1608P-473-W-T5 not present on the ERA-3ARW473V. If the application environment requires anti-sulfur protection (corrosive or high-sulfur atmospheres), the RG1608P-473-W-T5 is the appropriate selection. For standard industrial or automotive environments, the ERA-3ARW473V is functionally equivalent.

Q: Are there height clearance considerations between these parts?

A: The RG1608P-473-W-T5 has a maximum seated height of 0.020" (0.50mm), while the ERA-3ARW473V is 0.022" (0.55mm). For PCB designs with tight vertical clearance constraints, the RG1608P-473-W-T5 provides a 0.002" (0.05mm) advantage. For most standard applications, this difference is negligible.

Q: Are both parts compliant with automotive standards?

A: Yes. Both the RG1608P-473-W-T5 and ERA-3ARW473V carry AEC-Q200 automotive qualification and are ROHS3 compliant. Both are suitable for automotive applications without additional qualification requirements.

Q: What is the packaging format for both parts?

A: Both parts are supplied in Tape & Reel (TR) format in 0603 (1608 Metric) package. This packaging is standard for automated PCB assembly processes and is compatible with standard pick-and-place equipment.
