LR1F30K1 Equivalent & Substitute Parts

Part Overview

The LR1F30K1 is a 30.1 kOhms ±1% 0.6W through-hole resistor manufactured by TE Connectivity Passive Product in the Neohm series. This axial metal film resistor operates across a temperature range of -55°C to 155°C with a temperature coefficient of ±50ppm/°C. The component is currently active in production and ROHS3 compliant. Substitute parts are identified when equivalent electrical specifications and mechanical compatibility exist, enabling component procurement flexibility across multiple manufacturers and packaging formats.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LR1F30K1 is determined by strict equivalence across the following parameters: resistance value (30.1 kOhms), tolerance (±1%), power rating (0.6W), composition (metal film), temperature coefficient (±50ppm/°C), operating temperature range (-55°C ~ 155°C), package type (axial), and compliance certifications (ROHS3). The identified substitute parts—MRS25000C3012FCT00 and MRS25000C3012FRP00—meet all electrical specifications and mechanical requirements. These parts differ only in packaging format (cut tape versus tape and reel) and physical dimensions within acceptable tolerances for axial resistor applications. Both substitute parts are manufactured by Vishay Beyschlag/Draloric/BC Components and maintain active product status.

Parameter Comparison

Engineering Selection Recommendations

All three resistor options—LR1F30K1, MRS25000C3012FCT00, and MRS25000C3012FRP00—are active products with ROHS3 compliance and REACH unaffected status. Selection between these parts is based on packaging and procurement requirements rather than electrical performance, as all components meet identical electrical specifications. The LR1F30K1 is supplied in Tape & Box format with 1098 pieces in stock. The MRS25000C3012FCT00 is available in Cut Tape format with 2825 pieces in stock. The MRS25000C3012FRP00 is available in Tape & Reel format with 2268 pieces in stock. Physical dimensions vary slightly between the TE Connectivity part (2.30mm x 6.20mm) and Vishay parts (2.50mm x 6.50mm), which may affect board layout considerations in space-constrained applications. All parts carry identical ECCN (EAR99) and HTSUS (8533.21.0090) classifications.

Frequently Asked Questions (FAQ)

Q: Can MRS25000C3012FCT00 and MRS25000C3012FRP00 be used interchangeably with LR1F30K1?

A: Yes. All three parts meet identical electrical specifications: 30.1 kOhms ±1% resistance, 0.6W power rating, ±50ppm/°C temperature coefficient, and -55°C to 155°C operating range. Differences exist only in packaging format and physical dimensions.

Q: What is the difference between the two Vishay substitute parts?

A: MRS25000C3012FCT00 is supplied in Cut Tape (CT) format, while MRS25000C3012FRP00 is supplied in Tape & Reel (TR) format. Both parts are electrically and mechanically identical. Selection depends on assembly equipment compatibility and procurement volume requirements.

Q: Are there dimensional compatibility concerns when substituting parts?

A: The LR1F30K1 measures 0.091" diameter x 0.244" length (2.30mm x 6.20mm), while both Vishay substitutes measure 0.098" diameter x 0.256" length (2.50mm x 6.50mm). These dimensional differences are within typical axial resistor tolerances but should be verified against specific board layout constraints.

Q: Do all parts meet the same compliance requirements?

A: Yes. All three parts are ROHS3 compliant, carry EAR99 ECCN classification, and share the same HTSUS code (8533.21.0090). The Vishay parts have REACH Unaffected status, while the TE Connectivity part has Vendor Undefined REACH status.

Q: Which part should be selected for high-volume production?

A: Selection depends on assembly equipment and procurement strategy. The Tape & Reel format (MRS25000C3012FRP00) is typically preferred for automated assembly with 2268 pieces available. Cut Tape format (MRS25000C3012FCT00) offers 2825 pieces in stock for alternative handling requirements.
