Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RS010R2500FS73 is determined by the following critical parameters:

• Resistance value: 250 mOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power rating: 10W (exact match required)
• Composition: Wirewound (exact match required)
• Package type: Axial (exact match required)
• Physical dimensions: 0.375" Dia x 1.780" L (exact match required)
• Operating temperature range: -65°C ~ 250°C (exact match required)
• Moisture resistance feature: Required

The RS010R2500FE73 meets all electrical and mechanical parameters. The primary difference is packaging format: the main part is supplied in tape and reel (TR) configuration, while the substitute is supplied in cut tape (CT) configuration. Both variants are from the same RS series and maintain identical electrical performance and physical specifications.

Parameter Comparison

Engineering Selection Recommendations

The RS010R2500FE73 is a direct parametric equivalent to the RS010R2500FS73. Selection between these parts should be based on the following factors:

Packaging Requirements: Choose RS010R2500FS73 when tape and reel packaging is specified for automated assembly processes. Select RS010R2500FE73 when cut tape packaging is acceptable or preferred for manual assembly or lower-volume applications.

Compliance Requirements: The RS010R2500FE73 offers ROHS3 compliance and REACH unaffected status, making it suitable for applications with stricter environmental regulations. The RS010R2500FS73 is RoHS non-compliant and REACH affected, requiring evaluation against specific procurement standards.

Availability: Both parts are active and in stock. The RS010R2500FE73 has higher inventory availability (2,171 units versus 1,061 units).

Both parts share identical electrical specifications, physical dimensions, and thermal operating ranges, ensuring functional interchangeability within the specified parameters.

Frequently Asked Questions (FAQ)

Q: Can RS010R2500FE73 be used as a direct replacement for RS010R2500FS73?

A: Yes, the RS010R2500FE73 is a parametric equivalent. All electrical characteristics, physical dimensions, and operating parameters are identical. The only difference is the packaging format (cut tape versus tape and reel).

Q: What is the difference between tape and reel (TR) and cut tape (CT) packaging?

A: Tape and reel packaging supplies components on a continuous reel suitable for automated pick-and-place assembly equipment. Cut tape packaging supplies components on individual tape segments, typically used for manual assembly or lower-volume production runs. Both formats contain the same component.

Q: Are there any performance differences between these two parts?

A: No. Both parts have identical resistance values (250 mOhms), tolerance (±1%), power rating (10W), composition (wirewound), physical dimensions, and operating temperature range (-65°C ~ 250°C).

Q: Which part should I select for RoHS-compliant applications?

A: The RS010R2500FE73 is ROHS3 compliant and REACH unaffected. The RS010R2500FS73 is RoHS non-compliant and REACH affected. Verify your application's compliance requirements before selection.

Q: Can these parts be used interchangeably in PCB assembly?

A: Yes, provided the assembly process accommodates the packaging format. Both parts have identical lead configurations, physical dimensions, and electrical specifications. Verify that your assembly equipment or manual assembly process is compatible with the selected packaging format.
