Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the ELJ-SA150KF are qualified based on the following criteria:

• Inductance value: 15 µH (exact match required)
• Tolerance: ±10% (matching specification)
• Package / Case: 1210 (3225 Metric) (identical form factor)
• Shielding: Shielded (electromagnetic containment requirement)
• Mounting Type: Surface Mount (assembly compatibility)
• Moisture Sensitivity Level: 1 (Unlimited) (handling and storage compatibility)

The substitute parts listed below meet these core electrical and mechanical parameters. Current rating and DC resistance may vary within acceptable ranges for the application, provided the substitute part's current rating meets or exceeds the design requirement.

Parameter Comparison

Engineering Selection Recommendations

For applications requiring direct replacement of the obsolete ELJ-SA150KF:

S1210R-153K is the primary substitute. This part maintains identical inductance, tolerance, and package specifications while offering higher current rating (254 mA vs. 15 mA) and lower DC resistance (2.5Ohm vs. 2.2Ohm). The part is ROHS3 compliant and carries active product status with 1741 units in stock, ensuring long-term availability.

SP1210R-153K is an alternative substitute offering superior electrical performance with the lowest DC resistance (1.8Ohm Max) and highest current rating (338 mA). This part features drum core, wirewound construction and is ROHS3 compliant. Selection of this part is appropriate when lower losses or higher current headroom is required.

S1210-153K is a substitute option with identical electrical specifications to S1210R-153K but carries RoHS non-compliant status. This part should be selected only when RoHS compliance is not a design requirement.

Frequently Asked Questions (FAQ)

Q: Can S1210-153K, S1210R-153K, and SP1210R-153K be used interchangeably with ELJ-SA150KF?

A: Yes, all three parts meet the core substitution criteria: 15 µH inductance, ±10% tolerance, 1210 (3225 Metric) package, shielded construction, and surface mount configuration. The higher current ratings of the substitute parts (254 mA and 338 mA respectively) exceed the original 15 mA requirement, making them electrically compatible for this application.

Q: What is the difference between S1210R-153K and SP1210R-153K?

A: Both parts share identical inductance, tolerance, and package specifications. SP1210R-153K features drum core, wirewound construction with lower DC resistance (1.8Ohm vs. 2.5Ohm) and higher current rating (338 mA vs. 254 mA). Selection depends on whether the application benefits from reduced losses or requires higher current capacity.

Q: Why is S1210-153K listed as RoHS non-compliant while S1210R-153K is ROHS3 compliant?

A: Both parts are manufactured by API Delevan Inc. with identical electrical specifications. The RoHS compliance difference reflects manufacturing process or material composition changes. For new designs or applications with RoHS requirements, S1210R-153K or SP1210R-153K are the appropriate selections.

Q: Are there any physical dimension differences between the main part and substitutes?

A: All parts conform to the 1210 (3225 Metric) package standard. Minor dimensional variations exist within tolerance: ELJ-SA150KF measures 0.126" L x 0.098" W x 0.094" H (max), while API Delevan substitutes measure 0.128" L x 0.095" W x 0.101" H (max). These variations remain within standard PCB footprint tolerances and do not affect assembly compatibility.

Q: What is the Moisture Sensitivity Level (MSL) for all parts?

A: All parts, including the main part and all substitutes, carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or assembly processes.
