Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 09M1002FF is determined by the following criteria:

Electrical Compatibility Requirements:

• Resistance value: 10kΩ at 25°C (exact match required)
• Resistance tolerance: ±1% or tighter
• NTC thermistor type with comparable thermal response

Mechanical Compatibility Requirements:

• Lead wire length within acceptable tolerance of 1.42" (36.00mm)
• Through-hole or free-hanging mounting capability
• Physical dimensions compatible with existing PCB footprints

Compliance Requirements:

• ROHS3 compliance mandatory
• REACH unaffected status required
• Active or standard product status preferred

The NJ28MA0103F-- from KYOCERA AVX meets all substitution criteria through matching electrical specifications, compatible lead length, and active product status with enhanced thermal performance data.

Parameter Comparison

Engineering Selection Recommendations

For New Designs: The NJ28MA0103F-- is the appropriate selection. It maintains electrical equivalence through matching 10kΩ resistance and ±1% tolerance while offering active product status, eliminating obsolescence risk. The component provides documented thermal performance data (B25/85 = 3960K) and defined operating temperature range (-55°C ~ 150°C), enabling precise circuit design.

For Existing Designs Using 09M1002FF: Direct substitution with NJ28MA0103F-- is feasible provided the following conditions are met:

• PCB footprint accommodates the disc package geometry (2.8mm Dia x 2.8mm W)
• Lead length difference of 0.04" (1.00mm) does not impact mechanical assembly
• Thermal response characteristics at B25/85 = 3960K are acceptable for the application

Both components maintain ROHS3 compliance and REACH unaffected status, satisfying regulatory requirements.

Frequently Asked Questions (FAQ)

Q: Can the NJ28MA0103F-- directly replace the 09M1002FF without circuit modifications?

A: Electrical substitution is direct due to identical 10kΩ resistance and ±1% tolerance specifications. However, physical package differences (bead versus disc) require PCB footprint verification. Lead length tolerance of ±0.04" is typically acceptable in through-hole applications.

Q: What is the significance of the B25/85 value listed for the substitute?

A: The B25/85 = 3960K parameter defines the thermistor's thermal coefficient between 25°C and 85°C, characterizing its temperature-dependent resistance behavior. This data enables precise thermal response calculations in temperature sensing circuits. The original part does not specify this value.

Q: Are there any compliance differences between these components?

A: Both components are ROHS3 compliant and REACH unaffected. No compliance barriers exist for substitution. The primary difference is product status: the original is not recommended for new designs, while the substitute maintains active status.

Q: How do the package types affect component selection?

A: The 09M1002FF uses a bead package (free-hanging configuration), while the NJ28MA0103F-- uses a disc package (2.8mm diameter, 2.8mm width, through-hole mounting). Physical dimensions and mounting methods differ. Verify that the PCB footprint and assembly process accommodate the disc geometry before substitution.

Q: Is the 0.04" lead length difference significant?

A: The lead length difference (36.00mm versus 35.00mm) is within standard manufacturing tolerances for through-hole components. This difference is typically negligible for PCB assembly and does not affect electrical performance.
