RS010100K0FS73 Equivalent & Substitute Parts

Part Overview

The RS010100K0FS73 is a 100 kOhms ±1% 10W through-hole resistor with axial leads, manufactured by Vishay Dale. This wirewound resistor features moisture-resistant construction and operates across a wide temperature range from -65°C to 250°C. The part is currently active in production and available in Tape & Reel packaging. Substitute parts are identified when packaging format changes or compliance requirements differ while maintaining identical electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RS010100K0FS73 is determined by equivalence in the following critical parameters: resistance value (100 kOhms), tolerance (±1%), power rating (10W), composition (wirewound), package type (axial), temperature coefficient (±20ppm/°C), operating temperature range (-65°C to 250°C), and physical dimensions (0.375" Dia x 1.780" L). The primary variable between the main part and its substitute is packaging format. The RS010100K0FS73 is supplied in Tape & Reel format, while the RS010100K0FE73 is supplied in Cut Tape format. Both parts are manufactured by Vishay Dale and share identical electrical and mechanical specifications, making them functionally interchangeable in applications where packaging format does not impose constraints.

Parameter Comparison

Engineering Selection Recommendations

Selection between RS010100K0FS73 and RS010100K0FE73 depends on packaging requirements and regulatory compliance constraints. Both parts are active products from Vishay Dale with identical electrical and mechanical specifications. The RS010100K0FE73 offers ROHS3 compliance and REACH unaffected status, making it suitable for applications subject to these regulatory frameworks. The RS010100K0FS73 maintains RoHS non-compliant and REACH affected status. Packaging format differs between the two: Tape & Reel for RS010100K0FS73 supports automated assembly processes, while Cut Tape format for RS010100K0FE73 accommodates manual or semi-automated handling. Selection should be based on assembly process requirements and applicable regulatory standards for the end application.

Frequently Asked Questions (FAQ)

Q: Are RS010100K0FS73 and RS010100K0FE73 electrically identical? A: Yes. Both parts share identical resistance (100 kOhms), tolerance (±1%), power rating (10W), temperature coefficient (±20ppm/°C), and operating temperature range (-65°C to 250°C). Electrical performance is equivalent.

Q: What is the difference between Tape & Reel and Cut Tape packaging? A: Tape & Reel packaging supplies components on continuous tape wound on reels, optimized for high-volume automated assembly. Cut Tape packaging supplies components on tape segments, suitable for lower-volume or manual assembly processes. Both formats contain identical components.

Q: Can I substitute RS010100K0FE73 for RS010100K0FS73 in my assembly process? A: Substitution is possible if your assembly equipment can accommodate Cut Tape format instead of Tape & Reel format. Electrical and mechanical compatibility is confirmed; packaging format compatibility must be verified with your assembly process requirements.

Q: What are the compliance differences between these parts? A: RS010100K0FS73 is RoHS non-compliant and REACH affected. RS010100K0FE73 is ROHS3 compliant and REACH unaffected. Applications subject to RoHS3 or REACH regulations should use RS010100K0FE73.

Q: Are the physical dimensions identical? A: Yes. Both parts have identical axial package dimensions of 0.375" Dia x 1.780" L (9.53mm x 45.21mm), ensuring mechanical compatibility in PCB layouts and through-hole applications.
