Key Parameters

Substitute Part Grouping Explanation

Substitution of the CKP20162R2M-T is determined by the following critical parameters: inductance value (2.2 µH), package form factor (0806 / 2016 Metric), mounting type (surface mount), core material (ferrite), and current handling capability. All substitute parts listed maintain the identical inductance specification and package dimensions. The primary distinction between the main part and substitutes is the shielding configuration: the CKP20162R2M-T is unshielded, while all Pulse Electronics BKPB series alternatives are shielded. Current rating compatibility is evaluated based on application requirements, with substitutes available at both 1.0 A and 1.2 A ratings. DC resistance values vary across the substitute options, ranging from 110mOhm to 130mOhm, all within acceptable tolerance for equivalent circuit performance. All substitute parts are active products with current manufacturing status and full RoHS3 compliance.

Parameter Comparison

Engineering Selection Recommendations

The CKP20162R2M-T is classified as obsolete, making transition to an active substitute part necessary for continued component availability. All four Pulse Electronics BKPB series alternatives maintain full mechanical and electrical compatibility with the original specification, including identical package dimensions, inductance value, and ferrite core construction.

BKPB002016102R2MA6 is the primary recommended substitute for applications requiring the full 1.2 A current rating of the original part. This variant provides superior DC resistance performance at 110mOhm compared to the original 140mOhm specification, resulting in lower power dissipation. The extended operating temperature range of -55°C to 125°C provides additional thermal margin beyond the original -40°C to 85°C specification. Shielding configuration differs from the original unshielded design; applications sensitive to electromagnetic coupling should evaluate this change against circuit requirements.

BKPB002016102R2MA2 and BKPB002016102R2TA2 are suitable for applications with reduced current requirements of 1.0 A. Both maintain the 130mOhm DC resistance specification and are available in active production status. BKPB002016102R2MA2 maintains the ±20% inductance tolerance matching the original part, while BKPB002016102R2TA2 specifies ±30% tolerance.

BKPB002016102R2TA6 provides equivalent electrical performance to BKPB002016102R2TA2 with the highest available inventory level, supporting high-volume production requirements.

All substitute parts carry ROHS3 compliance and MSL 1 (Unlimited) moisture sensitivity rating, matching the environmental qualification of the original part.

Frequently Asked Questions (FAQ)

Q: Can BKPB002016102R2MA2 or BKPB002016102R2TA2 be used as direct replacements for CKP20162R2M-T in applications requiring 1.2 A continuous current?

A: No. BKPB002016102R2MA2 and BKPB002016102R2TA2 are rated for 1.0 A maximum continuous current, which is below the 1.2 A requirement of the original part. Use of these variants in 1.2 A applications will result in inductor saturation and thermal stress. BKPB002016102R2MA6 is the appropriate substitute for 1.2 A applications.

Q: What is the impact of shielding differences between the original unshielded CKP20162R2M-T and the shielded BKPB substitutes?

A: Shielded inductors reduce electromagnetic radiation and susceptibility to external magnetic fields compared to unshielded designs. In circuits where the inductor is isolated from sensitive components or where EMI performance is not critical, shielding provides no functional disadvantage. In circuits with tightly coupled components or stringent EMI requirements, the shielded design may alter circuit behavior. Circuit-level evaluation is required to confirm compatibility.

Q: Are all substitute parts available in the same packaging format as the original CKP20162R2M-T?

A: Yes. All substitute parts are packaged in 0806 (2016 Metric) surface mount form factor with identical footprint dimensions of 2.00mm length by 1.60mm width and 1.00mm maximum seated height. Direct PCB footprint compatibility is maintained.

Q: What is the significance of the inductance tolerance difference between BKPB002016102R2MA2 (±20%) and BKPB002016102R2TA2 (±30%)?

A: BKPB002016102R2MA2 maintains the ±20% inductance tolerance of the original CKP20162R2M-T, providing tighter inductance specification control. BKPB002016102R2TA2 specifies ±30% tolerance, representing a wider acceptable inductance range. Selection between these variants depends on circuit sensitivity to inductance variation. Applications with tight tuning or resonance requirements should use the ±20% tolerance variant.

Q: How does the DC resistance difference between CKP20162R2M-T (140mOhm) and BKPB002016102R2MA6 (110mOhm) affect circuit performance?

A: Lower DC resistance reduces resistive power loss in the inductor. BKPB002016102R2MA6 dissipates approximately 21% less power than the original part at rated current, resulting in lower operating temperature and improved efficiency. This represents a performance improvement over the original specification.

Q: Are the substitute parts suitable for applications operating at the original temperature extremes of -40°C to 85°C?

A: Yes. All substitute parts operate across the extended temperature range of -55°C to 125°C, which fully encompasses the original -40°C to 85°C specification. The extended range provides additional thermal margin for applications approaching temperature limits.

Q: What is the current saturation rating of the substitute parts, and how does it compare to the original?

A: The original CKP20162R2M-T does not specify a saturation current value. All Pulse Electronics BKPB substitutes specify 400mA saturation current. This parameter indicates the current level at which inductor performance begins to degrade due to core saturation. Applications should operate below this threshold to maintain specified inductance characteristics.
