Substitute Part Grouping Explanation

Substitute parts for the CM6296R-454 are identified based on the following criteria:

Mechanical Compatibility:

• Same series designation (CM6296R)
• Identical mounting type (Surface Mount)
• Identical package configuration (Horizontal, 4 PC Pad)
• Identical physical dimensions (1.058" L x 1.058" W; 0.423" Max Height)

Electrical Parameters:

• Same number of lines (2-line configuration)
• Same frequency reference (1 kHz)
• Operating temperature range compatibility (-55°C ~ 125°C)

Compliance & Status:

• Active product status
• RoHS3 compliance
• REACH unaffected status

The CM6296R-304 qualifies as a parametric equivalent within the CM6296R series. While inductance and current ratings differ, the substitute maintains identical mechanical form factor, mounting configuration, and compliance certifications, allowing direct PCB footprint compatibility.

Parameter Comparison

Engineering Selection Recommendations

CM6296R-454 Primary Selection: Use the CM6296R-454 when the application requires 450 µH inductance at 1 kHz with a maximum current rating of 6.5A and DC resistance specification of 24 mOhm maximum.

CM6296R-304 Substitute Selection: The CM6296R-304 provides an alternative within the same mechanical package and series. This substitute offers reduced inductance (300 µH) and increased current capacity (7.5A) with lower DC resistance (20 mOhm). Selection of the substitute is valid when circuit design permits the lower inductance value and the higher current rating does not create thermal or performance concerns.

Both parts maintain Active product status, ROHS3 compliance, and identical physical form factors, ensuring PCB compatibility and regulatory alignment.

Frequently Asked Questions (FAQ)

Q: Can CM6296R-304 be used as a direct replacement for CM6296R-454?

A: Direct PCB footprint replacement is possible due to identical mechanical dimensions, mounting type, and package configuration. However, circuit performance depends on inductance and current rating requirements. The CM6296R-304 provides 300 µH instead of 450 µH and supports 7.5A instead of 6.5A. Verify that the application circuit tolerates these electrical parameter differences.

Q: What are the key mechanical compatibility factors?

A: Both parts share identical specifications: 1.058" L x 1.058" W (26.87mm x 26.87mm) footprint, 0.423" (10.74mm) maximum height, Horizontal 4 PC Pad package configuration, and Surface Mount mounting type. These parameters ensure PCB layout compatibility.

Q: Are both parts RoHS3 compliant?

A: Yes. Both CM6296R-454 and CM6296R-304 are ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component manufacturing and distribution.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -55°C to 125°C, ensuring thermal compatibility in equivalent applications.

Q: How do the DC resistance values compare?

A: CM6296R-454 specifies 24 mOhm maximum DC resistance, while CM6296R-304 specifies 20 mOhm maximum. The lower resistance of the substitute may reduce power dissipation in high-current applications.

Q: Are both parts currently available?

A: Both parts maintain Active product status. CM6296R-454 has 779 pieces in stock; CM6296R-304 has 1244 pieces in stock as new original inventory.
