Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ISC1210ER5R6J are qualified based on the following electrical and mechanical parameters:

Critical Matching Parameters:

• Inductance value: 5.6 µH with ±5% tolerance
• Package / Case: 1210 (3225 Metric) surface mount
• Inductance frequency test: 7.96 MHz
• Mounting type: Surface Mount
• RoHS compliance: ROHS3 Compliant

Allowable Variations:

• Current rating: Substitute parts may have lower current ratings (200 mA vs. 210 mA) provided the application does not exceed the substitute's rating
• DC resistance: Substitute parts may have higher DCR (1.6 Ohm vs. 1.4 Ohm max) within acceptable circuit performance margins
• Core material: Substitutes may use ferrite core instead of iron powder, provided inductance and Q factor specifications are maintained
• Shielding: Substitutes may be unshielded, provided EMI performance requirements are met in the application
• Operating temperature: Substitute parts may have narrower temperature ranges (-40°C to 105°C vs. -55°C to 125°C)
• Self-resonant frequency: Substitute parts may have lower SRF (45 MHz vs. 50 MHz)

Parameter Comparison

Engineering Selection Recommendations

NLV32T-5R6J-EF is the primary substitute for the ISC1210ER5R6J. Both parts maintain identical inductance (5.6 µH), tolerance (±5%), Q factor (30 @ 7.96 MHz), and package dimensions (1210 / 3225 Metric). The NLV32T-5R6J-EF is ROHS3 compliant and carries Active product status, suitable for new designs. The primary differences are reduced current rating (200 mA vs. 210 mA), increased DCR (1.6 Ohm vs. 1.4 Ohm), unshielded construction, and narrower operating temperature range (-40°C to 105°C vs. -55°C to 125°C). Selection of this substitute requires verification that the application current does not exceed 200 mA and that the operating environment remains within -40°C to 105°C.

NLV32T-5R6J-PF is an alternative substitute with identical electrical specifications to the NLV32T-5R6J-EF. However, this part carries Not For New Designs product status and should not be selected for new circuit designs. This part is suitable only for legacy system maintenance or replacement applications where the original design specified this component.

For applications requiring the full -55°C to 125°C operating temperature range or shielded construction, the ISC1210ER5R6J remains the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can NLV32T-5R6J-EF replace ISC1210ER5R6J in all applications?

A: Substitution is valid when the application current does not exceed 200 mA, operating temperature remains within -40°C to 105°C, and unshielded inductor construction is acceptable. If the circuit requires shielding or operates outside the specified temperature range, the ISC1210ER5R6J is required.

Q: What is the impact of increased DC resistance in the substitute parts?

A: The NLV32T-5R6J series has 1.6 Ohm maximum DCR compared to 1.4 Ohm for the ISC1210ER5R6J. This 0.2 Ohm increase results in higher power dissipation at rated current. Circuit analysis is required to confirm acceptable thermal performance at the application's operating current.

Q: Why is NLV32T-5R6J-PF marked "Not For New Designs"?

A: This designation indicates the part is in mature or end-of-life status. While functionally equivalent, NLV32T-5R6J-PF should not be selected for new circuit designs. Use NLV32T-5R6J-EF for new applications or the ISC1210ER5R6J if the original specifications cannot be compromised.

Q: Are the package dimensions identical between all three parts?

A: Package dimensions are nearly identical. The ISC1210ER5R6J measures 0.126" L x 0.098" W x 0.095" H (3.20mm x 2.49mm x 2.41mm), while both TDK substitutes measure 0.126" L x 0.098" W x 0.094" H (3.20mm x 2.50mm x 2.40mm). These differences are within standard PCB assembly tolerances and do not affect mechanical compatibility.

Q: What is the difference between shielded and unshielded construction?

A: The ISC1210ER5R6J features shielded construction, which reduces electromagnetic interference (EMI) radiation and susceptibility. The NLV32T-5R6J series are unshielded. Unshielded inductors may introduce EMI in sensitive circuits. Substitution requires confirmation that EMI performance remains acceptable in the application environment.

Q: How do the self-resonant frequencies compare?

A: The ISC1210ER5R6J has a self-resonant frequency of 50 MHz, while both NLV32T-5R6J variants are rated at 45 MHz. This 5 MHz difference may affect high-frequency circuit performance. Applications operating near or above 45 MHz require detailed frequency response analysis before substitution.
