Substitute Part Grouping Explanation

Substitution of the 1210-152J is determined by strict equivalence across all critical electrical and mechanical parameters. The substitute part must match the following criteria:

Electrical Parameters (Non-Negotiable):

Inductance value: 1.5 µH
Inductance tolerance: ±5%
Current rating: 467 mA minimum
DC resistance: 850 mOhm maximum
Core material: Ferrite
Shielding configuration: Unshielded
Operating temperature range: -55°C to 125°C minimum
Q factor: 30 @ 7.9 MHz
Self resonant frequency: 85 MHz

Mechanical Parameters (Non-Negotiable):

Package / Case: 1210 (3225 Metric)
Mounting type: Surface Mount
Physical dimensions: 0.128" L × 0.095" W (3.25 mm × 2.42 mm)
Maximum seated height: 0.101" (2.57 mm)
Packaging format: Tape & Reel (TR)

The 1210R-152J from API Delevan Inc. meets all electrical and mechanical equivalence criteria and qualifies as a direct substitute.

Engineering Selection Recommendations

1210-152J Selection Criteria: The 1210-152J is suitable for applications where RoHS non-compliant components are acceptable or required by legacy system specifications. This part maintains active production status and is available in standard inventory quantities (1800 Pcs).

1210R-152J Selection Criteria: The 1210R-152J is the preferred substitute when ROHS3 compliance is a design or procurement requirement. This variant maintains identical electrical performance and mechanical compatibility while meeting modern environmental compliance standards. Inventory availability is confirmed at 1210 Pcs.

Compliance Considerations: Both parts carry REACH Unaffected status and EAR99 export classification. The primary differentiation between these parts is RoHS compliance status. Selection between 1210-152J and 1210R-152J should be based on the specific compliance requirements of the end application and regional regulations.

Frequently Asked Questions (FAQ)

Q: Can the 1210R-152J replace the 1210-152J in existing designs?

A: Yes. The 1210R-152J is electrically and mechanically equivalent to the 1210-152J. All critical parameters including inductance, current rating, DC resistance, frequency response, and physical dimensions are identical. Direct substitution is possible without circuit redesign or PCB layout modification.

Q: What is the difference between 1210-152J and 1210R-152J?

A: The primary difference is RoHS compliance status. The 1210-152J is RoHS non-compliant, while the 1210R-152J is ROHS3 compliant. All electrical and mechanical specifications are identical.

Q: Are there any package or footprint differences between these parts?

A: No. Both parts use the identical 1210 (3225 Metric) surface mount package with matching physical dimensions (0.128" L × 0.095" W) and maximum seated height (0.101"). PCB footprints are interchangeable.

Q: Which part should I specify for new designs?

A: Selection depends on compliance requirements. For applications requiring ROHS3 compliance, specify 1210R-152J. For legacy systems or applications where RoHS compliance is not mandated, either part is acceptable based on availability and cost considerations.

Q: Are the electrical performance characteristics identical?

A: Yes. Both parts have identical inductance (1.5 µH ±5%), current rating (467 mA), DC resistance (850 mOhm max), Q factor (30 @ 7.9 MHz), self resonant frequency (85 MHz), and operating temperature range (-55°C to 125°C).

Q: What is the moisture sensitivity level for these inductors?

A: Both parts have Moisture Sensitivity Level (MSL) 1, which indicates unlimited shelf life without moisture control requirements.
