HPC2C101K Equivalent & Substitute Parts Reference

Part Overview

The HPC2C101K is a 100 Ohms ±10% 2W through-hole axial resistor manufactured by KOA Speer Electronics, Inc. This leaded ceramic resistor is designed for automotive applications with AEC-Q200 qualification, non-inductive construction, and pulse withstanding capability. The component is currently in active production status with 649 pieces available in stock. Alternative equivalent parts may be required due to supply chain constraints, design flexibility, or specific application requirements where substitute specifications align with system tolerances.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HPC2C101K is determined by strict alignment of the following critical parameters:

Critical Matching Parameters:

• Resistance value: 100 Ohms (exact match required)
• Tolerance: ±10% (exact match required)
• Power rating: 2W (exact match required)
• Composition: Ceramic (exact match required)
• Package configuration: Axial through-hole (exact match required)
• Operating temperature range: Minimum -40°C to +200°C or higher
• Termination count: 2 (exact match required)

Acceptable Variation Parameters:

• Physical dimensions (length and diameter) may vary within PCB layout constraints
• Temperature coefficient values may differ within acceptable performance bands
• Additional features (moisture resistance) do not disqualify substitution

The OY101KE from Ohmite meets all critical matching parameters and qualifies as a direct equivalent substitute for the HPC2C101K.

Parameter Comparison

Engineering Selection Recommendations

The OY101KE qualifies as a direct electrical and functional equivalent to the HPC2C101K based on matching critical electrical parameters: 100 Ohms resistance, ±10% tolerance, 2W power rating, ceramic composition, and axial package configuration. Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements for equivalent component selection.

The OY101KE provides an extended operating temperature range (-40°C ~ 220°C versus -40°C ~ 200°C), which represents a performance advantage in high-temperature applications. The OY101KE includes moisture-resistant construction as an additional feature, which does not conflict with the non-inductive specification of the HPC2C101K.

Physical dimension differences must be verified against PCB layout constraints. The OY101KE has a larger diameter (7.00mm versus 5.00mm) and shorter length (19.00mm versus 23.00mm). Confirm that board-level spacing and component placement accommodate the OY101KE footprint before final selection.

Both components are active production items with established supply availability.

Frequently Asked Questions (FAQ)

Q: Can the OY101KE replace the HPC2C101K in automotive AEC-Q200 applications?

A: The OY101KE is electrically equivalent to the HPC2C101K in all critical parameters (resistance, tolerance, power rating, composition, and package). However, the OY101KE does not carry explicit AEC-Q200 certification in the provided specifications. If AEC-Q200 qualification is a mandatory design requirement, the HPC2C101K must be retained. If AEC-Q200 is preferred but not contractually required, the OY101KE qualifies as a functional substitute.

Q: What are the physical dimension differences, and do they affect substitution?

A: The HPC2C101K measures 5.00mm diameter × 23.00mm length, while the OY101KE measures 7.00mm diameter × 19.00mm length. The OY101KE is thicker but shorter. Substitution is possible only if the PCB layout provides adequate clearance for the larger diameter and the shorter length does not create mechanical stress on solder joints or component leads. Verify board-level spacing before implementation.

Q: Are there temperature performance differences between these components?

A: The OY101KE operates across -40°C ~ 220°C, exceeding the HPC2C101K range of -40°C ~ 200°C. Temperature coefficient values differ slightly (-1000 / -1600 ppm/°C for OY101KE versus -700 / -1800 ppm/°C for HPC2C101K), but both fall within acceptable performance bands for standard resistor applications. The OY101KE is suitable for applications requiring extended high-temperature performance.

Q: Do compliance certifications match between these parts?

A: Both the HPC2C101K and OY101KE are ROHS3 compliant and REACH unaffected. Regulatory compliance is equivalent. No additional compliance verification is required for substitution from a regulatory standpoint.

Q: What is the primary reason to substitute the HPC2C101K with the OY101KE?

A: Substitution is justified by supply availability, cost optimization, or design flexibility when AEC-Q200 certification is not contractually mandated. The OY101KE provides equivalent electrical performance with enhanced moisture resistance and extended temperature range. Physical dimensions must be verified for PCB compatibility.
