RG1608P-513-W-T1 Equivalent & Substitute Parts

Part Overview

The RG1608P-513-W-T1 is a 51 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 to provide alternative sourcing options when the primary part becomes unavailable or when design requirements necessitate component alternatives that maintain electrical and mechanical compatibility.

Substitute Part Grouping Explanation

Substitution of the RG1608P-513-W-T1 is determined by strict equivalence across the following critical parameters:

Electrical Parameters:

• Resistance value: 51 kOhms (exact match required)
• Tolerance: ±0.05% (exact match required)
• Power rating: 0.1W / 1/10W (exact match required)
• Operating temperature range: -55°C ~ 155°C (exact match required)

Mechanical Parameters:

• Package format: 0603 (1608 Metric) (exact match required)
• Number of terminations: 2 (exact match required)
• Physical dimensions: 0.063" L x 0.031" W (1.60mm x 0.80mm) (exact match required)

Compliance & Certification:

• Automotive AEC-Q200 rating (required for automotive applications)
• RoHS3 compliance (required for regulatory conformance)
• Thin film composition (required for precision tolerance specification)

Substitute parts RG1608N-513-W-T1 and ERA-3ARW513V meet all critical electrical, mechanical, and compliance requirements. Temperature coefficient variations (±25ppm/°C vs. ±10ppm/°C) and anti-sulfur feature differences do not prevent substitution but represent performance distinctions within the allowed parameter set.

Engineering Selection Recommendations

RG1608N-513-W-T1 (Direct Substitute - Susumu)

The RG1608N-513-W-T1 is a direct substitute manufactured by Susumu. This part maintains identical electrical specifications, package format, and compliance certifications. The temperature coefficient is improved at ±10ppm/°C compared to the main part's ±25ppm/°C, representing enhanced thermal stability. Both parts carry AEC-Q200 automotive qualification and ROHS3 compliance. This substitute is suitable for direct replacement in all applications where the RG1608P-513-W-T1 is specified.

ERA-3ARW513V (Cross-Manufacturer Substitute - Panasonic)

The ERA-3ARW513V is a cross-manufacturer substitute produced by Panasonic Electronic Components. This part meets all critical electrical parameters, package specifications, and compliance requirements. The temperature coefficient is ±10ppm/°C, providing improved thermal performance. The seated height is 0.022" (0.55mm) compared to 0.020" (0.50mm) for the main part, a 0.002" (0.05mm) difference within typical PCB assembly tolerances. AEC-Q200 automotive qualification and ROHS3 compliance are maintained. This substitute is suitable for applications requiring cross-manufacturer sourcing flexibility.

Frequently Asked Questions (FAQ)

Q: Can RG1608N-513-W-T1 be used as a direct replacement for RG1608P-513-W-T1?

A: Yes. Both parts are manufactured by Susumu with identical resistance (51 kOhms), tolerance (±0.05%), power rating (0.1W), package format (0603), and operating temperature range (-55°C ~ 155°C).
