LR1F115K Equivalent & Substitute Parts

Part Overview

The LR1F115K is a 115 kOhms ±1% 0.6W through-hole resistor manufactured by TE Connectivity Passive Product in the Neohm series. This axial metal film resistor is designed for applications requiring precision resistance values with tight tolerance specifications and moderate power dissipation. The part maintains Active product status with 946 units in current inventory. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when procurement requirements necessitate alternative manufacturers or packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LR1F115K is determined by matching the following critical electrical and mechanical parameters:

Electrical Parameters:

• Resistance value: 115 kOhms
• Tolerance: ±1%
• Power rating: 0.6W
• Temperature coefficient: ±50ppm/°C
• Operating temperature range: -55°C ~ 155°C

Mechanical Parameters:

• Package type: Axial
• Composition: Metal Film
• Number of terminations: 2

Compliance Parameters:

• RoHS3 Compliance
• ECCN classification: EAR99
• HTSUS code: 8533.21.0090

The MRS25000C1153FCT00 manufactured by Vishay Beyschlag/Draloric/BC Components satisfies all substitution criteria. Both parts are metal film axial resistors with identical electrical specifications and compliance certifications. Dimensional variations exist between the two parts; however, both conform to standard axial resistor form factors suitable for through-hole PCB applications.

Parameter Comparison

Engineering Selection Recommendations

Both the LR1F115K and MRS25000C1153FCT00 are Active status products with full ROHS3 compliance and EAR99 export classification. Selection between these parts is based on the following factors:

Inventory Availability: The MRS25000C1153FCT00 maintains higher inventory levels (2909 units) compared to the LR1F115K (946 units), providing greater supply continuity for high-volume applications.

Packaging Configuration: The LR1F115K is supplied in Tape & Box format, suitable for automated assembly processes. The MRS25000C1153FCT00 is supplied in Cut Tape format, appropriate for manual or semi-automated placement.

Physical Dimensions: The MRS25000C1153FCT00 exhibits slightly larger physical dimensions (0.098" diameter x 0.256" length) compared to the LR1F115K (0.091" diameter x 0.244" length). PCB layout constraints may influence part selection when space is limited.

Compliance Status: The MRS25000C1153FCT00 carries explicit REACH Unaffected designation, while the LR1F115K lists REACH status as Vendor Undefined. Applications subject to REACH compliance requirements should prioritize the Vishay part.

Frequently Asked Questions (FAQ)

Q: Can the MRS25000C1153FCT00 be used as a direct replacement for the LR1F115K?

A: Yes. Both parts are 115 kOhms ±1% metal film axial resistors with 0.6W power rating and identical temperature coefficients and operating ranges. Electrical performance is equivalent. Physical dimensions differ slightly; verify PCB layout compatibility before substitution.

Q: What is the significance of the packaging difference between Tape & Box and Cut Tape?

A: Tape & Box packaging is optimized for automated pick-and-place assembly with full reel quantities. Cut Tape packaging provides individual component segments suitable for manual assembly or lower-volume applications. The choice depends on manufacturing process requirements rather than component performance.

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

A: Both parts are ROHS3 compliant and carry EAR99 export classification. The MRS25000C1153FCT00 explicitly states REACH Unaffected status, while the LR1F115K lists REACH status as Vendor Undefined. For applications requiring confirmed REACH compliance documentation, the Vishay part provides explicit certification.

Q: Do the dimensional differences affect circuit performance?

A: No. The dimensional variations between the two parts do not affect electrical performance. Both conform to standard axial resistor form factors. Dimensional differences are relevant only for PCB layout and mechanical spacing considerations.

Q: What parameters must remain constant for substitution eligibility?

A: Resistance value (115 kOhms), tolerance (±1%), power rating (0.6W), temperature coefficient (±50ppm/°C), operating temperature range (-55°C ~ 155°C), composition (metal film), and package type (axial) must all match for valid substitution.
