Substitute Part Grouping Explanation

Substitution eligibility for the SCX147-201 is determined by the following critical parameters:

• Coil Configuration: 2-coil inductor array with identical series and parallel inductance values (802.82 µH series, 200 µH parallel)
• Inductance Tolerance: ±20% tolerance band
• Current Ratings: 640 mA parallel configuration, 320 mA series configuration
• DC Resistance: 545 mOhm maximum (parallel), 2.18 Ohm maximum (series)
• Shielding Type: Unshielded construction
• Mounting Technology: Surface mount package
• Compliance: ROHS3 compliant, MSL Level 1

The CTX200-4-R from Eaton - Electronics Division meets all substitution criteria within the specified tolerance and performance parameters.

Parameter Comparison

Engineering Selection Recommendations

The CTX200-4-R is the qualified substitute for the obsolete SCX147-201 based on the following engineering criteria:

Electrical Equivalence: All critical electrical parameters match within specified tolerances. The parallel inductance of 200.7 µH falls within the ±20% tolerance band of the original 200 µH specification. Series inductance, current ratings, and DC resistance values are identical.

Compliance Status: Both components maintain ROHS3 compliance and MSL Level 1 rating, ensuring compatibility with current manufacturing and environmental standards.

Product Availability: The CTX200-4-R is classified as active product status with 4400 units in stock, providing procurement continuity for the obsolete SCX147-201.

Mechanical Compatibility: Both components are surface mount, unshielded 2-coil inductor arrays in nonstandard packages with comparable physical dimensions (14.40mm x 14.40mm x 7.00mm for SCX147-201 versus 13.97mm x 13.97mm x 6.35mm for CTX200-4-R).

Frequently Asked Questions (FAQ)

Q: Can the CTX200-4-R directly replace the SCX147-201 in existing designs?

A: Yes. The CTX200-4-R meets all electrical and mechanical substitution criteria. The parallel inductance variance of 0.7 µH (200.7 µH versus 200 µH) is within the ±20% tolerance specification. All current ratings, DC resistance values, and compliance certifications are identical.

Q: What is the difference in physical dimensions between these parts?

A: The SCX147-201 measures 14.40mm x 14.40mm x 7.00mm, while the CTX200-4-R measures 13.97mm x 13.97mm x 6.35mm. Both are nonstandard package formats. Verify PCB layout compatibility before implementation.

Q: Are there packaging differences between the original and substitute?

A: The SCX147-201 packaging format is not specified in available data. The CTX200-4-R is supplied in Tape & Reel (TR) format. Confirm packaging requirements for your procurement and assembly processes.

Q: Why is the SCX147-201 classified as obsolete?

A: Product obsolescence is determined by the manufacturer. The CTX200-4-R, as an active product from Eaton - Electronics Division, provides functional continuity for applications requiring 2-coil inductor arrays with 200 µH parallel and 802.82 µH series configurations.

Q: Are the operating temperature ranges compatible?

A: The SCX147-201 operating temperature range is not specified in available documentation. The CTX200-4-R operates across -40°C to 85°C. Confirm your application's temperature requirements against the CTX200-4-R specification.

Q: What compliance certifications apply to both components?

A: Both the SCX147-201 and CTX200-4-R are ROHS3 compliant with MSL Level 1 rating. Both carry EAR99 ECCN classification. The CTX200-4-R is REACH unaffected.
