RS01A2R500FS70 Equivalent & Substitute Parts

Part Overview

The RS01A2R500FS70 is a 2.5 Ohm, 1W wirewound axial resistor manufactured by Vishay Dale. This moisture-resistant through-hole component operates across a temperature range of -65°C to 250°C with ±1% tolerance and ±50ppm/°C temperature coefficient. The part is currently active in production and available in Tape & Reel packaging with 1080 pieces in stock. Substitute parts are identified when packaging format differs while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RS01A2R500FS70 is determined by matching the following critical parameters: resistance value (2.5 Ohms), tolerance (±1%), power rating (1W), composition (wirewound), package case (axial), temperature coefficient (±50ppm/°C), operating temperature range (-65°C to 250°C), physical dimensions (0.094" Dia x 0.406" L), and feature set (moisture resistant). The primary variable distinguishing substitute parts is packaging format. The RS01A2R500FE70 qualifies as a direct substitute, differing only in packaging configuration (Cut Tape versus Tape & Reel), while maintaining all electrical and mechanical specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RS01A2R500FS70 and RS01A2R500FE70 are active production components from Vishay Dale with identical electrical and mechanical characteristics. Selection between these parts depends on packaging requirements. The RS01A2R500FS70 in Tape & Reel format is suitable for automated assembly processes requiring continuous reel feeding. The RS01A2R500FE70 in Cut Tape format accommodates manual assembly workflows or applications requiring smaller quantity dispensing. The RS01A2R500FE70 carries ROHS3 compliance and REACH Unaffected status, while the RS01A2R500FS70 is RoHS non-compliant and REACH Affected. Both parts share EAR99 ECCN classification and 8533.21.0080 HTSUS code.

Frequently Asked Questions (FAQ)

Q: Can RS01A2R500FE70 replace RS01A2R500FS70 in circuit applications? A: Yes. Both parts are electrically and mechanically identical, with matching resistance (2.5 Ohms), tolerance (±1%), power rating (1W), temperature coefficient (±50ppm/°C), and operating range (-65°C to 250°C). Substitution is valid from a functional standpoint.

Q: What is the primary difference between these two parts? A: The packaging format differs. RS01A2R500FS70 is supplied in Tape & Reel (TR) configuration, while RS01A2R500FE70 is supplied in Cut Tape (CT) configuration. Physical component dimensions and electrical specifications remain identical.

Q: Which packaging format should I select for my application? A: Tape & Reel format (RS01A2R500FS70) is optimized for high-volume automated assembly with pick-and-place equipment. Cut Tape format (RS01A2R500FE70) is suitable for manual assembly, prototyping, or lower-volume production runs.

Q: Are there compliance differences between these parts? A: Yes. RS01A2R500FE70 is ROHS3 compliant and REACH Unaffected. RS01A2R500FS70 is RoHS non-compliant and REACH Affected. Compliance requirements should be verified against your application and regional regulations.

Q: Do both parts have the same physical dimensions? A: Yes. Both parts measure 0.094" diameter by 0.406" length (2.39mm x 10.31mm) and feature identical axial package geometry with two terminations.
