MOSX3C1R0J Equivalent & Substitute Parts

Part Overview

The MOSX3C1R0J is a 1 Ohms ±5% 3W through hole resistor manufactured by KOA Speer Electronics, Inc. as part of the MOS series. This metal oxide film resistor features flame retardant coating and safety characteristics, designed for axial through-hole applications. The part is currently active in production with 1078 units in stock. Substitute parts are identified to provide alternative sourcing options when the primary part number is unavailable or when packaging requirements differ.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the MOSX3C1R0J are identified based on strict electrical and mechanical parameter matching. The primary substitution criterion is equivalence across all critical parameters: resistance value (1 Ohms), tolerance (±5%), power rating (3W), composition (metal oxide film), package configuration (axial), temperature coefficient (±300ppm/°C), and operating temperature range (-55°C ~ 200°C). Physical dimensions must remain identical (0.236" Dia x 15.50mm L). The only permitted variation is packaging format, where bulk packaging may be substituted with cut tape (CT) packaging, as both deliver the same component with identical electrical and mechanical specifications. All substitute parts must maintain ROHS3 compliance and the same series designation (MOS).

Parameter Comparison

Engineering Selection Recommendations

Both the MOSX3C1R0J and MOSX3CT631R1R0J are active production parts from KOA Speer Electronics, Inc., with identical electrical and mechanical specifications. Selection between these parts should be based on packaging requirements and assembly process compatibility. The bulk-packaged MOSX3C1R0J is suitable for manual assembly or applications where loose component handling is acceptable. The cut tape packaged MOSX3CT631R1R0J is designed for automated pick-and-place assembly systems and tape-based component feeders. Both parts maintain ROHS3 compliance and are suitable for applications requiring flame retardant, safety-rated metal oxide film resistors in the -55°C to 200°C operating range. Inventory availability should be evaluated based on current stock levels and project timeline requirements.

Frequently Asked Questions (FAQ)

Q: Can MOSX3CT631R1R0J be used as a direct replacement for MOSX3C1R0J?

A: Yes. Both parts are electrically and mechanically identical, with matching resistance (1 Ohms), tolerance (±5%), power rating (3W), temperature coefficient (±300ppm/°C), and operating temperature range (-55°C ~ 200°C). The only difference is packaging format: bulk versus cut tape. Direct substitution is valid provided the receiving assembly process is compatible with the cut tape format.

Q: What is the difference between bulk and cut tape packaging?

A: Bulk packaging delivers components loose in a container, suitable for manual assembly or bin-based component storage. Cut tape packaging delivers components on continuous carrier tape with individual component pockets, designed for automated pick-and-place assembly equipment. Electrical and mechanical performance is identical between the two formats.

Q: Are there any compliance or certification differences between these parts?

A: No. Both MOSX3C1R0J and MOSX3CT631R1R0J maintain identical RoHS3 compliance status, REACH unaffected status, and EAR99 export classification. Both are manufactured to the same specifications and quality standards.

Q: Can these parts be used interchangeably in high-temperature applications?

A: Yes. Both parts are rated for the same operating temperature range of -55°C to 200°C and maintain identical temperature coefficient specifications (±300ppm/°C). They are suitable for equivalent high-temperature applications.

Q: What should be considered when selecting between these substitute parts?

A: Selection should be based on assembly process requirements (manual versus automated), packaging format compatibility with existing component feeders, and current inventory availability. Electrical performance and reliability are equivalent between both options.
