Key Parameters

Substitute Part Grouping Explanation

Substitution of the ELL-CTV560M is determined by strict alignment of core electrical and mechanical parameters:

Critical Matching Parameters:

• Inductance value: 56 µH at ±20% tolerance
• Core material and shielding: Ferrite, shielded drum core construction
• Mounting technology: Surface mount
• Test frequency: 100 kHz
• Package classification: Nonstandard drum core form factor

Allowable Variation Parameters:

• Current rating: Substitute must meet or exceed 1.6 A minimum
• DC resistance: Substitute must not exceed 100 mOhm maximum
• Physical dimensions: Minor variations acceptable within nonstandard drum core envelope
• Compliance certifications: ROHS3 and MSL ratings must be maintained

The SRR1260-560M from Bourns Inc. satisfies all critical matching parameters and exceeds minimum current and resistance specifications, qualifying as a direct functional equivalent.

Parameter Comparison

Engineering Selection Recommendations

The SRR1260-560M qualifies as a direct substitute based on the following engineering criteria:

Electrical Compatibility: Both components maintain identical inductance values at 56 µH with ±20% tolerance and operate at the same 100 kHz test frequency. The substitute's 2.3 A current rating exceeds the original 1.6 A requirement, providing design margin. DC resistance of 100 mOhm maximum remains within acceptable limits relative to the original 87 mOhm specification.

Mechanical and Environmental Compliance: Both parts utilize ferrite shielded drum core construction in surface mount nonstandard packages. Moisture sensitivity levels and RoHS3 compliance are identical, ensuring compatibility with existing manufacturing and environmental specifications.

Product Status Advantage: The SRR1260-560M carries active product status with established supply chain availability (2388 pcs in stock), addressing the obsolescence constraint of the ELL-CTV560M.

Frequently Asked Questions (FAQ)

Q: Can the SRR1260-560M directly replace the ELL-CTV560M in existing designs?

A: Yes. Both components share identical inductance values, tolerance, core type, shielding, and mounting technology. The substitute meets all critical electrical parameters and exceeds current rating specifications.

Q: What is the significance of the higher current rating in the substitute part?

A: The SRR1260-560M's 2.3 A rating versus the original 1.6 A provides additional thermal and operational margin. This does not affect circuit functionality and represents an improvement in component robustness.

Q: Are there dimensional differences between these parts?

A: Minor dimensional variations exist within the nonstandard drum core envelope. The ELL-CTV560M measures 12.00mm × 12.00mm × 4.50mm (max height), while the SRR1260-560M measures 12.50mm × 12.50mm × 6.50mm (max height). PCB layout verification is required to confirm fit within available space constraints.

Q: Do both parts meet the same compliance requirements?

A: Yes. Both components are ROHS3 compliant with MSL rating 1 (Unlimited), maintaining compatibility with standard manufacturing and environmental specifications.

Q: Why is the substitute part's DC resistance specification listed as "Max" rather than a fixed value?

A: The SRR1260-560M specifies 100 mOhm maximum, indicating the upper tolerance limit. This remains acceptable relative to the original 87 mOhm specification and does not impact circuit performance within normal operating conditions.
