Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DRQ125-151-R is determined by strict alignment across the following critical parameters:

Electrical Specifications:

• Inductance values in both parallel and series configurations must fall within the ±20% tolerance band established for this product category
• Current ratings (parallel and series) must meet or exceed the original part specifications
• DC resistance values must not exceed the maximum thresholds of the original component
• Current saturation ratings must maintain performance parity

Mechanical & Physical Compatibility:

• Dual 2-coil inductor array configuration is mandatory
• Shielded construction is required
• Surface mount mounting type is required
• Physical footprint dimensions (12.50 mm × 12.50 mm) must be maintained
• Height tolerance must accommodate PCB assembly processes

Environmental & Compliance Requirements:

• Operating temperature range must encompass -40°C to 125°C minimum
• RoHS3 compliance is mandatory
• Moisture Sensitivity Level 1 (Unlimited) classification is required
• Packaging format must be Tape & Reel (TR)

The SRF1260-151M from Bourns Inc. qualifies as a direct substitute based on these criteria.

Engineering Selection Recommendations

Primary Substitute: SRF1260-151M (Bourns Inc.)

The SRF1260-151M is qualified as a direct substitute for the DRQ125-151-R based on complete electrical and mechanical parameter alignment. Both components maintain Active product status, ensuring ongoing manufacturer support and supply availability. The inductance values in both parallel (150 µH vs. 151.1 µH) and series (600 µH vs. 604.4 µH) configurations remain within the ±20% tolerance specification established for this product category. Current ratings, saturation characteristics, and DC resistance values are identical or superior in the Bourns component.

Both parts carry ROHS3 compliance certification and Moisture Sensitivity Level 1 classification, confirming equivalent environmental and regulatory standing. The physical footprint dimensions (12.50 mm × 12.50 mm) are identical, with the SRF1260-151M height of 6.20 mm remaining compatible with standard PCB assembly processes relative to the DRQ125-151-R height of 6.00 mm. Tape & Reel packaging format is consistent across both components, supporting automated assembly workflows.

Selection between these components may be based on supplier availability, lead time requirements, or cost considerations, as electrical and mechanical performance characteristics are equivalent.

Frequently Asked Questions (FAQ)

Q: Can the SRF1260-151M be used as a direct replacement for the DRQ125-151-R in existing designs?

A: Yes. The SRF1260-151M meets all electrical and mechanical substitution criteria. Inductance values fall within the ±20% tolerance band, current ratings are identical, and physical dimensions are compatible with existing PCB layouts. Both components are shielded, surface mount, and operate across the same temperature range.

Q: What is the significance of the ±20% tolerance specification?

A: The ±20% tolerance defines the acceptable inductance variation range for this product category. The DRQ125-151-R parallel inductance of 151.1 µH and the SRF1260-151M parallel inductance of 150 µH both fall within this tolerance band, confirming functional equivalence in circuit applications.

Q: Are there physical dimension differences that affect PCB assembly?

A: The footprint dimensions (12.50 mm × 12.50 mm) are identical. The height difference (6.00 mm vs. 6.20 mm) is 0.20 mm and remains within standard PCB assembly tolerances. This minor variation does not impact component placement or clearance requirements.

Q: Do both parts carry the same environmental compliance certifications?

A: Yes. Both the DRQ125-151-R and SRF1260-151M are ROHS3 compliant with Moisture Sensitivity Level 1 (Unlimited) classification. Environmental and regulatory requirements are equivalent.

Q: What packaging formats are available for these components?

A: Both components are supplied in Tape & Reel (TR) format, supporting automated pick-and-place assembly processes. This packaging format is standard for surface mount inductor arrays in this category.

Q: How do DC resistance values compare between the two parts?

A: The DRQ125-151-R parallel DCR is 248 mOhm, while the SRF1260-151M is specified at 254 mOhm maximum. For series configuration, the DRQ125-151-R is 991 mOhm versus 972 mOhm maximum for the SRF1260-151M. Both values remain within acceptable operating parameters for this product category.

Q: Are current saturation ratings identical?

A: Yes. Both components maintain identical current saturation ratings: 1.81 A for parallel configuration and 905 mA for series configuration. Saturation performance is equivalent.
