LR1F910K Equivalent & Substitute Parts

Part Overview

The LR1F910K is a 910 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 general-purpose applications requiring precision resistance values with tight tolerance specifications. The part is currently in active production status with 1,072 pieces available in inventory. Substitute parts are identified when equivalent electrical specifications, mechanical compatibility, and regulatory compliance are maintained across alternative manufacturers.

Substitute Part Grouping Explanation

Substitution eligibility for the LR1F910K is determined by strict equivalence across the following critical parameters:

Resistance Value: 910 kOhms (exact match required)
Tolerance: ±1% (exact match required)
Power Rating: 0.6W (exact match required)
Composition: Metal Film (exact match required)
Temperature Coefficient: ±50ppm/°C (exact match required)
Operating Temperature Range: -55°C ~ 155°C (exact match required)
Package Type: Axial (exact match required)
Regulatory Compliance: ROHS3 Compliant (minimum requirement)

The MRS25000C9103FCT00 manufactured by Vishay Beyschlag/Draloric/BC Components meets all substitution criteria. Physical dimensions vary slightly between the main part and substitute, but both maintain axial package compatibility for through-hole applications.

Engineering Selection Recommendations

Both the LR1F910K and MRS25000C9103FCT00 are active production components with full ROHS3 compliance. Selection between these parts is based on availability, packaging requirements, and supply chain considerations rather than electrical performance differences.

The LR1F910K is supplied in Tape & Box packaging format with 1,072 pieces currently in stock. The MRS25000C9103FCT00 is supplied in Cut Tape format with 6,873 pieces in inventory. Both components satisfy identical electrical and thermal specifications for 910 kOhms ±1% 0.6W axial metal film resistor applications.

Physical dimensions show minor variation: the TE Connectivity part measures 2.30mm diameter by 6.20mm length, while the Vishay part measures 2.50mm diameter by 6.50mm length. Both dimensions remain within standard axial resistor form factors and are compatible with through-hole PCB layouts designed for 0.6W axial resistors.

Frequently Asked Questions (FAQ)

Q: Can the MRS25000C9103FCT00 be used as a direct replacement for the LR1F910K?

A: Yes. Both components share identical electrical specifications: 910 kOhms resistance, ±1% tolerance, 0.6W power rating, metal film composition, ±50ppm/°C temperature coefficient, and -55°C to 155°C operating range. Both are ROHS3 compliant and feature two terminations in axial package configuration.

Q: What is the difference in physical dimensions between these parts?

A: The LR1F910K measures 2.30mm diameter by 6.20mm length. The MRS25000C9103FCT00 measures 2.50mm diameter by 6.50mm length. Both dimensions are within standard axial resistor specifications and compatible with PCB layouts designed for through-hole axial components in this power class.

Q: Does the packaging format difference affect compatibility?

A: Packaging format (Tape & Box versus Cut Tape) affects supply chain logistics and handling procedures but does not impact electrical or mechanical compatibility. Component selection between these formats depends on assembly process requirements and inventory management practices.

Q: Are both parts suitable for the full operating temperature range?

A: Yes. Both the LR1F910K and MRS25000C9103FCT00 operate across the identical temperature range of -55°C to 155°C with a temperature coefficient of ±50ppm/°C.

Q: What regulatory certifications apply to both parts?

A: Both components are ROHS3 compliant. The LR1F910K carries REACH status as Vendor Undefined. The MRS25000C9103FCT00 carries REACH status as REACH Unaffected. Both are classified under ECCN EAR99 and HTSUS 8533.21.0090.
