Key Parameters

Substitute Part Grouping Explanation

Substitution of the IMS05EB502K is determined by the following critical parameters:

Primary Matching Criteria:

• Inductance value: 5 mH (exact match required)
• Mounting type: Through hole axial configuration
• Operating temperature range: -55°C to 105°C minimum
• Regulatory compliance: ROHS3 and REACH standards

Secondary Compatibility Factors:

• Inductance tolerance specification
• Core material type (ferrite or iron)
• Shielding configuration
• Physical envelope dimensions
• DC resistance characteristics

The substitute part 2500R-62J meets the primary inductance, mounting, temperature, and compliance requirements. However, differences exist in shielding type, core material, tolerance, and physical dimensions that must be evaluated for specific application requirements.

Parameter Comparison

Engineering Selection Recommendations

The 2500R-62J serves as an active substitute for the obsolete IMS05EB502K based on matching inductance value, through-hole axial mounting configuration, and identical operating temperature range of -55°C to 105°C. Both components maintain ROHS3 compliance and REACH unaffected status.

Key Differences Requiring Application Assessment:

The substitute part features tighter inductance tolerance (±5% versus ±10%), which provides improved consistency. However, the 2500R-62J is unshielded compared to the shielded design of the original part. This difference is significant for applications requiring electromagnetic interference mitigation. The substitute utilizes iron core material versus ferrite core in the original, affecting frequency response characteristics and Q factor performance.

Physical dimensions differ substantially: the substitute is larger (0.240" Dia x 0.740" L) compared to the original (0.162" Dia x 0.410" L). PCB layout and mechanical clearance must be verified before substitution.

The substitute part specifies 58 mA current rating and 50 Ohm maximum DC resistance, providing defined electrical performance parameters absent from the original part specification.

Frequently Asked Questions (FAQ)

Q: Can the 2500R-62J directly replace the IMS05EB502K in all applications?

A: The 2500R-62J matches the 5 mH inductance value and operating temperature range, enabling functional substitution for inductance-dependent circuits. However, application-specific factors must be evaluated: shielding requirements, electromagnetic compatibility needs, available PCB space for the larger physical envelope, and current handling capacity.

Q: What is the significance of the shielding difference?

A: The IMS05EB502K features shielding to contain electromagnetic fields and reduce radiated emissions. The 2500R-62J is unshielded, allowing electromagnetic field radiation. Applications sensitive to EMI or requiring low radiated emissions may not tolerate this substitution without additional circuit-level filtering or shielding measures.

Q: How do the core materials affect performance?

A: The ferrite core in the original part and iron core in the substitute exhibit different frequency response characteristics. The original part is tested at 7.9 MHz, while the substitute is tested at 250 kHz. This reflects different core material behavior across frequency ranges. Application frequency requirements determine compatibility.

Q: Are the physical dimension differences critical?

A: The substitute part is significantly larger (0.240" Dia x 0.740" L versus 0.162" Dia x 0.410" L). PCB layout, component density, and mechanical clearance constraints must be verified. Space-constrained designs may not accommodate the larger substitute.

Q: Does the tighter tolerance of the substitute provide advantages?

A: The 2500R-62J tolerance of ±5% is tighter than the original ±10%, providing improved inductance consistency across production batches. This benefits applications requiring precise inductance values for frequency-dependent circuit performance.

Q: What compliance certifications apply to both parts?

A: Both the IMS05EB502K and 2500R-62J maintain ROHS3 compliance and REACH unaffected status, ensuring regulatory compatibility for applications subject to these standards.
