SC15R22KT Equivalent & Substitute Parts

Part Overview

The SC15R22KT is a 220 nH shielded inductor manufactured by TE Connectivity Passive Product, designed for through-hole axial mounting applications. This component delivers a current rating of 2.06 A with a maximum DC resistance of 55 mOhm and operates across a temperature range of -55°C to 100°C. The part is currently active in production and maintains ROHS3 compliance with MSL 1 rating.

Substitute parts are identified when equivalent electrical performance can be achieved within the specified parameter tolerances while maintaining functional compatibility in the target application circuit.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SC15R22KT is determined by the following critical parameters:

Electrical Equivalence Criteria:

• Inductance value of 220 nH within ±10% tolerance
• DC resistance maximum of 55 mOhm
• Q factor of 50 at 25 MHz test frequency
• Self resonant frequency of 450 MHz or higher
• Current rating sufficient for application requirements

Mechanical Compatibility Criteria:

• Through-hole axial mounting configuration
• Physical dimensions compatible with PCB layout constraints

Environmental & Compliance Criteria:

• Operating temperature range covering -55°C to 100°C minimum
• RoHS compliance status for regulated applications

The ER1537-02KR from API Delevan Inc. meets the core electrical specifications (220 nH inductance, 55 mOhm DCR, 50 Q @ 25 MHz) and mechanical requirements (through-hole axial). However, design-specific considerations regarding shielding characteristics and current rating capacity must be evaluated for the target application.

Engineering Selection Recommendations

SC15R22KT Selection Criteria:

The SC15R22KT is the primary choice for applications requiring shielded inductor performance with ROHS3 compliance. The shielded design reduces electromagnetic interference coupling to adjacent circuit elements. The 2.06 A current rating provides margin for applications with moderate to high current demands. ROHS3 compliance status qualifies this component for regulated markets and environmentally controlled supply chains.

ER1537-02KR Selection Criteria:

The ER1537-02KR serves as an alternative where the following conditions are met:

• Application circuit does not require shielding or operates in low-EMI environments
• Current requirements do not exceed 1.81 A
• Extended temperature operation to 125°C is beneficial
• RoHS non-compliance is acceptable for the target application
• Military-grade MIL-PRF-39010/06 qualification is required

The ER1537-02KR exhibits a slightly higher self-resonant frequency (460 MHz vs. 450 MHz), which may provide marginal performance advantage in high-frequency filtering applications.

Compliance Considerations:

Applications subject to RoHS directives must use SC15R22KT. Applications with military specifications or requiring MIL-PRF-39010/06 qualification must use ER1537-02KR. Packaging format differs (Tape & Box for SC15R22KT; Tape & Reel for ER1537-02KR), affecting procurement and assembly workflows.

Frequently Asked Questions (FAQ)

Q: Can ER1537-02KR replace SC15R22KT in all applications?

A: No. The ER1537-02KR has a lower current rating (1.81 A vs. 2.06 A) and lacks shielding. Substitution is valid only when application current requirements do not exceed 1.81 A and shielding is not required for EMI control.

Q: What is the impact of the shielding difference?

A: SC15R22KT shielding reduces radiated and conducted electromagnetic interference. ER1537-02KR, being unshielded, may couple more energy to adjacent circuit traces. Applications sensitive to EMI should retain SC15R22KT.

Q: Are the physical dimensions compatible?

A: Both components use axial through-hole mounting. SC15R22KT measures 0.165" diameter × 0.394" length; ER1537-02KR measures 0.156" diameter × 0.375" length. The ER1537-02KR is slightly smaller and will fit PCB layouts designed for SC15R22KT, though the reverse is not guaranteed.

Q: Which part should be used for RoHS-regulated applications?

A: SC15R22KT is ROHS3 compliant and must be used for applications subject to RoHS directives. ER1537-02KR is RoHS non-compliant and is unsuitable for regulated markets.

Q: What is the difference in packaging format?

A: SC15R22KT is supplied in Tape & Box (TB) format; ER1537-02KR is supplied in Tape & Reel (TR) format. TB packaging is typical for lower-volume orders and manual assembly; TR packaging is optimized for high-volume automated assembly.

Q: Can ER1537-02KR be used in applications requiring military specifications?

A: Yes. ER1537-02KR is qualified to MIL-PRF-39010/06 military standard. SC15R22KT does not carry military qualification. Applications with military requirements must use ER1537-02KR.

Q: What is the temperature operating range difference?

A: SC15R22KT operates from -55°C to 100°C; ER1537-02KR operates from -55°C to 125°C. For applications requiring operation above 100°C, ER1537-02KR provides extended thermal capability.

Q: Are the electrical parameters identical?

A: Core electrical parameters are equivalent: both have 220 nH inductance (±10%), 55 mOhm maximum DCR, and Q factor of 50 at 25 MHz. The ER1537-02KR has a marginally higher self-resonant frequency (460 MHz vs. 450 MHz).
