Key Parameters

Substitute Part Grouping Explanation

Substitution of the 07C5002JF is determined by the following critical parameters:

• Resistance Value: 50kΩ nominal resistance at 25°C
• Package Type: Bead configuration with free-hanging leads
• Tolerance Class: Resistance tolerance specification
• Compliance Standards: ROHS3 compliance requirement
• Lead Wire Dimensions: Physical lead length compatibility

The B57861S0503F040 from EPCOS - TDK Electronics qualifies as a direct substitute based on matching nominal resistance (50kΩ), identical package type (bead), free-hanging mounting configuration, and ROHS3 compliance. The substitute offers improved tolerance specifications (±1% vs. ±5%) and defined operating temperature range (-55°C to 155°C), making it suitable for applications previously served by the obsolete 07C5002JF.

Parameter Comparison

Engineering Selection Recommendations

The B57861S0503F040 is the qualified substitute for the obsolete 07C5002JF based on the following factors:

• Functional Equivalence: Both components provide 50kΩ NTC thermistor functionality in bead package configuration
• Compliance Alignment: Both parts maintain ROHS3 compliance, satisfying regulatory requirements
• Product Availability: The substitute is active in production with 3216 units in stock, ensuring supply continuity
• Tolerance Improvement: The substitute offers tighter resistance tolerance (±1% vs. ±5%), providing enhanced measurement accuracy
• Physical Compatibility: Lead wire length difference (37.50mm vs. 36.00mm) represents a 1.5mm variance, acceptable for most mechanical mounting scenarios
• Defined Operating Range: The substitute specifies -55°C to 155°C operating temperature, providing clear thermal performance boundaries

Frequently Asked Questions (FAQ)

Q: Can the B57861S0503F040 directly replace the 07C5002JF in existing designs?

A: Yes. Both components share identical nominal resistance (50kΩ), package type (bead), and mounting configuration (free-hanging). The 1.5mm lead wire length difference is typically accommodated in standard mounting applications.

Q: What is the significance of the improved tolerance specification?

A: The B57861S0503F040 provides ±1% resistance tolerance compared to the 07C5002JF's ±5%. This tighter tolerance reduces measurement uncertainty and improves circuit performance in temperature sensing applications requiring higher accuracy.

Q: Are there any compliance differences between these parts?

A: Both parts are ROHS3 compliant. The substitute includes REACH compliance documentation, providing additional regulatory coverage for European applications.

Q: Why is the 07C5002JF listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by Vishay Dale. The B57861S0503F040 remains in active production, ensuring long-term availability and supply chain stability.

Q: What is the B Value specification listed for the substitute?

A: The B25/100 value of 3760K characterizes the thermistor's temperature coefficient. This parameter defines the relationship between resistance change and temperature change, essential for thermal response calculations in sensor applications.
