Equivalent & Substitute Parts for LR1F9K53

Part Overview

The LR1F9K53 is a 9.53 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 and is ROHS3 compliant. The part is currently active in production. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements necessitate alternative manufacturers or packaging configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the LR1F9K53 is determined by strict equivalence across the following critical parameters:

• Resistance Value: 9.53 kOhms (exact match required)
• Tolerance: ±1% (exact match required)
• Power Rating: 0.6W (exact match required)
• Composition: Metal Film (exact match required)
• Package Type: Axial (exact match required)
• Temperature Coefficient: ±50ppm/°C (exact match required)
• Operating Temperature Range: -55°C to 155°C (exact match required)
• Termination Count: 2 (exact match required)
• Regulatory Compliance: ROHS3 Compliant (minimum requirement)

All identified substitute parts meet these criteria. Physical dimensions may vary within acceptable tolerances for through-hole axial components without affecting functional compatibility in standard PCB layouts.

Parameter Comparison

Engineering Selection Recommendations

All three parts are active products with ROHS3 compliance and identical electrical specifications. Selection between these parts is based on the following considerations:

LR1F9K53 (TE Connectivity): Primary specification. Compact axial dimensions (2.30mm diameter). Suitable for space-constrained applications.

MBB02070C9531FRP00 (Vishay): Automotive-grade component with AEC-Q200 qualification. Slightly larger physical dimensions (2.50mm diameter). Recommended for automotive applications or when automotive-grade reliability is required.

MRS25000C9531FCT00 (Vishay): Standard industrial-grade metal film resistor. Identical electrical performance to the primary part with slightly larger physical dimensions (2.50mm diameter). Suitable for general industrial applications.

All parts are functionally interchangeable in circuits where the electrical parameters are the controlling specification. Physical layout considerations may apply due to dimensional differences.

Frequently Asked Questions (FAQ)

Q: Can MBB02070C9531FRP00 be used as a direct replacement for LR1F9K53?

A: Yes. Both parts have identical electrical specifications: 9.53 kOhms ±1%, 0.6W power rating, metal film composition, ±50ppm/°C temperature coefficient, and -55°C to 155°C operating range. The MBB02070C9531FRP00 has slightly larger physical dimensions (2.50mm vs 2.30mm diameter) but remains compatible with standard through-hole PCB layouts.

Q: What is the difference between MBB02070C9531FRP00 and MRS25000C9531FCT00?

A: The primary difference is that MBB02070C9531FRP00 carries AEC-Q200 automotive qualification, while MRS25000C9531FCT00 is a standard industrial-grade component. Electrically and mechanically, both parts are equivalent. Selection depends on application requirements for automotive certification.

Q: Are there any packaging differences between these parts?

A: LR1F9K53 is supplied in Tape & Box (TB) packaging. MBB02070C9531FRP00 and MRS25000C9531FCT00 are supplied in Cut Tape (CT) packaging. This affects handling and automated assembly processes but does not impact component performance.

Q: Do physical dimension differences affect PCB compatibility?

A: The LR1F9K53 has a 2.30mm diameter, while both Vishay substitutes have 2.50mm diameter. These differences are within standard tolerances for through-hole axial components and do not prevent PCB mounting. Verify PCB hole spacing and component clearance for space-critical layouts.

Q: Are all parts RoHS compliant?

A: Yes. LR1F9K53, MBB02070C9531FRP00, and MRS25000C9531FCT00 are all ROHS3 compliant.

Q: Which part should be selected for new designs?

A: For general applications, any of the three parts meets the electrical specification. For automotive applications, MBB02070C9531FRP00 is recommended due to AEC-Q200 qualification. For space-constrained designs, LR1F9K53 offers the smallest physical footprint.
