Equivalent & Substitute Parts for 01C1002JF

Part Overview

The 01C1002JF is an NTC thermistor manufactured by Vishay Dale with a nominal resistance of 10kΩ at 25°C. This component is packaged as a bead-type thermistor with free-hanging leads and operates across a temperature range of 0°C to 70°C. The part carries a Product Status designation of "Not For New Designs," indicating that while functional units remain in inventory, this component is no longer recommended for new circuit development. Identifying equivalent substitute parts is necessary to support legacy system maintenance, repair operations, and to enable transition to active product lines where applicable.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 01C1002JF is determined by the following critical parameters:

• Nominal resistance value of 10kΩ at 25°C
• Resistance tolerance of ±5%
• Operating temperature capability (minimum 0°C to 70°C coverage required)
• Physical package compatibility (bead or disc form factor with comparable lead length)
• Electrical performance under specified thermal conditions

The ND03N00103J-- from KYOCERA AVX meets the core electrical specifications (10kΩ nominal resistance, ±5% tolerance) and provides extended operating temperature range (-55°C to 150°C), which encompasses the original part's 0°C to 70°C requirement. Lead wire length is comparable (1.38" vs. 1.42"), and the disc package form factor is mechanically compatible with free-hanging mounting applications.

Parameter Comparison

Engineering Selection Recommendations

The ND03N00103J-- qualifies as a functional equivalent for the 01C1002JF based on matching electrical specifications: both components provide 10kΩ nominal resistance at 25°C with ±5% tolerance. The substitute part's extended operating temperature range (-55°C to 150°C) fully covers the original part's 0°C to 70°C specification window.

Selection of the ND03N00103J-- is appropriate for applications where:

• Active product status is required for new procurement cycles
• Extended temperature operating margin is beneficial
• Through-hole mounting compatibility exists in the circuit design
• RoHS compliance requirements can accommodate non-compliant components in legacy or non-regulated applications

The 01C1002JF remains suitable for in-service maintenance of existing systems where component replacement is necessary and inventory availability permits.

Frequently Asked Questions (FAQ)

Q: Can the ND03N00103J-- directly replace the 01C1002JF in all applications?

A: Both components share identical nominal resistance (10kΩ) and tolerance (±5%) at 25°C. The substitute part's wider operating temperature range (-55°C to 150°C) is compatible with the original part's 0°C to 70°C specification. Physical differences exist: the substitute uses a disc package versus the original bead package, and mounting type differs (through-hole versus free-hanging). Circuit board layout and mounting provisions must accommodate these physical differences.

Q: What is the significance of the "Not For New Designs" status on the 01C1002JF?

A: This designation indicates the manufacturer has discontinued active support and new production of this component. The part remains available from existing inventory but is not recommended for incorporation into new product designs. The ND03N00103J--, with Active product status, is the recommended path for new development.

Q: Are there compliance differences between these parts?

A: The 01C1002JF is RoHS3 Compliant, while the ND03N00103J-- is RoHS non-compliant. Both parts carry REACH Unaffected status. Compliance requirements specific to the end application must be evaluated before substitution.

Q: How do the package differences affect circuit integration?

A: The 01C1002JF uses a bead package with free-hanging leads, while the ND03N00103J-- uses a disc package (4.6mm diameter × 3.0mm width) with through-hole mounting. Lead wire length is comparable (36.00mm versus 35.00mm). Physical board layout modifications may be required to accommodate the disc form factor and through-hole mounting configuration.

Q: What thermal performance differences exist between these thermistors?

A: Both components are specified with identical resistance tolerance (±5%) at 25°C. The ND03N00103J-- provides a B25/85 value of 4080K, which characterizes thermal response in the 25°C to 85°C range. The original part does not specify B-value parameters. For applications requiring precise thermal response characterization, the substitute part's defined B-value provides additional thermal performance documentation.
