Equivalent & Substitute Parts for 01C1001JF

Part Overview

The 01C1001JF is an NTC thermistor manufactured by Vishay Dale, featuring a 1kΩ resistance at 25°C in a bead package configuration. This component is classified as not for new designs, indicating it has been superseded in the manufacturer's product roadmap. The bead form factor and specified operating temperature range of 0°C to 70°C define its primary application scope. Identifying equivalent substitute parts is necessary due to the product's discontinued status and to ensure design continuity for existing applications or legacy system support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for NTC thermistor 01C1001JF is determined by the following critical parameters:

• Resistance value at 25°C: 1kΩ (exact match required)
• Resistance tolerance: ±5% (acceptable tolerance band)
• Package configuration: Bead or equivalent form factor
• Lead wire length: Approximately 1.38" to 1.42" (35mm to 36mm)
• Operating temperature capability: Minimum coverage of 0°C to 70°C range

The substitute part ND03J00102J-- from KYOCERA AVX meets the core electrical specifications (1kΩ resistance, ±5% tolerance) and physical dimensions (lead wire length 1.38"). Although packaged as a disc rather than a bead, the ND03 series maintains functional equivalence for temperature sensing applications within the specified operating range.

Parameter Comparison

Engineering Selection Recommendations

The ND03J00102J-- serves as an active substitute for the discontinued 01C1001JF. The substitute maintains electrical equivalence through identical 1kΩ resistance and ±5% tolerance specifications. The ND03J00102J-- offers an extended operating temperature range (-55°C to 150°C) that encompasses the original part's 0°C to 70°C specification, providing additional thermal margin for applications.

Design consideration: The ND03J00102J-- is RoHS non-compliant, whereas the original 01C1001JF is RoHS3 compliant. Applications subject to RoHS regulatory requirements must account for this compliance difference. The substitute's disc package and through-hole mounting configuration differ from the bead form factor and free-hanging mount of the original part; mechanical integration and PCB layout must be evaluated accordingly.

Frequently Asked Questions (FAQ)

Q: Can ND03J00102J-- directly replace 01C1001JF in existing designs?

A: Electrical substitution is valid based on matching 1kΩ resistance and ±5% tolerance. Mechanical integration requires assessment of the package transition from bead to disc form factor and mounting method change from free-hanging to through-hole configuration.

Q: What is the significance of the extended operating temperature range in ND03J00102J--?

A: The ND03J00102J-- operating range of -55°C to 150°C fully encompasses the original 01C1001JF range of 0°C to 70°C. This extended range does not affect substitution validity for applications operating within the original specification but provides additional thermal capability if future design requirements expand.

Q: How does the RoHS compliance difference affect substitution?

A: The original 01C1001JF is RoHS3 compliant; the substitute ND03J00102J-- is RoHS non-compliant. Applications requiring RoHS certification or regulatory compliance must evaluate whether this difference is acceptable for the intended market or application context.

Q: Are lead wire length differences significant?

A: Lead wire lengths are 1.42" (36.00mm) for 01C1001JF and 1.38" (35.00mm) for ND03J00102J--, a difference of 0.04" (1.00mm). This minimal variance is typically accommodated in standard PCB layouts and does not constitute a functional barrier to substitution.

Q: What is the B25/85 value listed for ND03J00102J--?

A: The B25/85 value of 3480K is a thermal sensitivity coefficient specific to the ND03 series. This parameter is not provided for the original 01C1001JF and does not affect substitution eligibility for applications requiring only the 1kΩ resistance specification.
