RS010R2000FS73 Equivalent & Substitute Parts

Part Overview

The RS010R2000FS73 is a 200 mOhms ±1% 10W through-hole wirewound axial resistor manufactured by Vishay Dale. This component is designed for applications requiring precision low-resistance dissipation in moisture-resistant environments. The part is currently active in production with 885 units in stock. Substitute parts are necessary to address packaging format preferences, compliance requirements, or inventory availability across different supply channels.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RS010R2000FS73 is determined by the following core parameters: resistance value (200 mOhms), tolerance (±1%), power rating (10W), composition (wirewound), package type (axial), and termination count (2). All substitute parts must match these electrical and mechanical specifications to ensure functional equivalence in circuit applications.

The identified substitutes are grouped into two categories:

Parametric Equivalent (Packaging Variant): RS010R2000FE73 matches all electrical parameters and physical dimensions of the main part. The primary difference is packaging format (Cut Tape versus Tape & Reel), which affects supply chain logistics but not component performance.

Manufacturer Recommended Equivalent (Cross-Manufacturer): 80FR20 (Ohmite Acrasil® 80 series) provides electrical equivalence across resistance, tolerance, and power rating. Physical dimensions show minor variation (0.406" Dia x 1.843" L versus 0.375" Dia x 1.780" L), which remains within acceptable mechanical tolerances for standard axial component mounting.

Parameter Comparison

Engineering Selection Recommendations

RS010R2000FE73 Selection Criteria: This substitute is appropriate when Cut Tape packaging is preferred over Tape & Reel format, or when higher inventory availability is required. The part maintains identical electrical specifications and physical dimensions. Selection of this variant should consider that it carries ROHS3 compliance status, whereas the main part does not.

80FR20 Selection Criteria: This cross-manufacturer substitute is appropriate when Ohmite component qualification is required or when bulk packaging is operationally preferred. The part maintains electrical equivalence across all critical parameters. Physical dimensions show minor variation; verification of PCB layout clearance is necessary prior to implementation. Temperature coefficient specification (±90ppm/°C) is provided for this part, whereas the main part does not specify this parameter.

All three parts carry EAR99 ECCN classification and share identical HTSUS code (8533.21.0080), indicating equivalent regulatory treatment for export and tariff purposes.

Frequently Asked Questions (FAQ)

Q: Can RS010R2000FE73 be used as a direct replacement for RS010R2000FS73?

A: Yes. Both parts are manufactured by Vishay Dale with identical electrical specifications (200 mOhms ±1%, 10W wirewound) and physical dimensions (0.375" Dia x 1.780" L). The only difference is packaging format (Cut Tape versus Tape & Reel). Circuit performance is equivalent.

Q: What are the mechanical considerations when substituting 80FR20 for RS010R2000FS73?

A: The 80FR20 has slightly larger dimensions (0.406" Dia x 1.843" L compared to 0.375" Dia x 1.780" L). Verify that PCB layout, component spacing, and mounting clearances accommodate this size variation before implementation.

Q: Does RoHS compliance status affect functional equivalence?

A: No. RoHS compliance is a regulatory and supply chain attribute, not a functional parameter. All three parts perform identically in circuit applications. Selection based on RoHS status depends on end-product regulatory requirements, not component performance.

Q: Are there temperature coefficient differences between these parts?

A: The main part (RS010R2000FS73) and RS010R2000FE73 do not specify temperature coefficient. The 80FR20 specifies ±90ppm/°C. For applications requiring temperature stability specifications, the 80FR20 provides documented performance data.

Q: Can these parts be used interchangeably in production?

A: Electrical interchangeability is confirmed. Mechanical interchangeability requires verification of PCB layout and mounting specifications, particularly for the 80FR20 due to dimensional variation. Packaging format differences (Tape & Reel, Cut Tape, Bulk) affect assembly line compatibility and must be evaluated against production equipment capabilities.
