Equivalent & Substitute Parts for Vishay Dale 09C1002JF

Part Overview

The Vishay Dale 09C1002JF is an NTC thermistor with 10kΩ resistance at 25°C, supplied in a bead package configuration. This component is classified as "Not For New Designs," indicating it has been superseded in the manufacturer's product line. Organizations requiring this thermistor for legacy system maintenance, repair, or continued production of existing designs must identify functionally equivalent alternatives that maintain the same electrical and mechanical characteristics.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for NTC thermistors is determined by the following parameters:

• Nominal resistance value at 25°C (10kΩ required)
• Resistance tolerance (±5% acceptable)
• Package form factor and physical dimensions
• Lead wire length and mounting configuration
• Thermal operating range compatibility
• RoHS and environmental compliance status

The KYOCERA AVX ND03N00103J-- meets the core electrical requirement of 10kΩ nominal resistance with ±5% tolerance. However, this substitute introduces a package form change from bead to disc configuration (3.5mm diameter × 3.0mm width) and modifies the mounting type from free hanging to through-hole. The lead wire length remains within acceptable tolerance at 1.38" (35.00mm). The substitute operates across -55°C to 150°C, providing extended thermal range coverage. RoHS compliance status differs between the main part (RoHS3 Compliant) and the substitute (RoHS non-compliant).

Parameter Comparison

Engineering Selection Recommendations

The KYOCERA AVX ND03N00103J-- provides electrical equivalence in resistance value and tolerance. Selection of this substitute requires evaluation of the following factors:

Package and Mounting Compatibility: The transition from bead to disc package and from free hanging to through-hole mounting necessitates PCB layout and mechanical assembly modifications. The 0.04" (1.00mm) reduction in lead wire length is negligible for most applications.

Compliance Requirements: The main part meets RoHS3 compliance, while the substitute is RoHS non-compliant. Organizations subject to RoHS regulations must verify that this substitution aligns with procurement and environmental compliance policies.

Product Status: The substitute is classified as Active, ensuring continued availability and manufacturer support, whereas the main part is Not For New Designs, indicating limited future availability.

Thermal Performance: The substitute provides an extended operating temperature range (-55°C to 150°C) compared to the unspecified range of the main part, offering potential thermal margin improvement in temperature-sensitive applications.

Frequently Asked Questions (FAQ)

Q: Can the KYOCERA AVX ND03N00103J-- be used as a direct drop-in replacement for the Vishay Dale 09C1002JF?

A: Electrical substitution is possible due to matching 10kΩ resistance and ±5% tolerance. However, the package change from bead to disc and the mounting type change from free hanging to through-hole require mechanical redesign. Direct PCB compatibility cannot be assumed without layout verification.

Q: What are the critical parameters for NTC thermistor substitution?

A: Nominal resistance value at 25°C, resistance tolerance, and thermal operating range are the primary electrical criteria. Package form, lead configuration, and mounting type determine mechanical compatibility. Environmental compliance certifications must align with application requirements.

Q: Does the RoHS non-compliance of the substitute part present a barrier to use?

A: RoHS compliance requirements depend on the end application, market region, and customer specifications. Organizations operating under RoHS mandates must confirm that non-compliant substitutes are acceptable for their specific use case before implementation.

Q: Are there dimensional constraints when substituting from bead to disc package?

A: Yes. The disc package (3.5mm diameter × 3.0mm width) occupies more board space than the bead configuration. PCB footprint, component spacing, and thermal dissipation pathways must be re-evaluated to ensure the substitute fits within the available assembly space.

Q: How does the extended operating temperature range of the substitute affect selection?

A: The KYOCERA AVX substitute operates from -55°C to 150°C, compared to the unspecified range of the main part. This extended range provides additional thermal margin and may improve performance in temperature-extreme environments, but does not affect substitution eligibility if the original operating range is unknown.
