Key Parameters

Substitute Part Grouping Explanation

Substitution of the SCX114-9R6 is determined by the following critical electrical and mechanical parameters:

• Inductance values: Parallel inductance must be 9.6 µH ±20% and series inductance must be 38.48 µH ±20%
• Current ratings: Parallel current rating must support 1.7 A and series current rating must support 850 mA
• DC resistance: Parallel DCR must not exceed 57 mOhm and series DCR must not exceed 227 mOhm
• Coil configuration: Exactly 2 coils required
• Shielding: Unshielded construction
• Mounting: Surface mount technology
• Package dimensions: Physical footprint compatibility within nonstandard package specifications
• Compliance: ROHS3 compliance and MSL Level 1 rating

The CTX10-1P-R from Eaton - Electronics Division meets all specified electrical and mechanical parameters within the defined tolerances and compliance requirements.

Parameter Comparison

Engineering Selection Recommendations

The CTX10-1P-R is the qualified substitute for the SCX114-9R6 based on the following engineering criteria:

Electrical Equivalence: All critical electrical parameters match or fall within specified tolerances. The parallel inductance of 9.62 µH is within the ±20% tolerance band of the 9.6 µH specification. Series inductance, current ratings, and DC resistance values are identical.

Mechanical Compatibility: Both components are surface mount, nonstandard package inductors with compatible footprints. The CTX10-1P-R has a slightly smaller footprint (0.450" x 0.450" versus 0.461" x 0.461") and lower profile (0.165" versus 0.217"), which provides layout flexibility without compromising performance.

Compliance and Availability: The CTX10-1P-R maintains ROHS3 compliance and MSL Level 1 rating, ensuring regulatory alignment. The substitute is in active production status, providing supply chain continuity and long-term availability compared to the obsolete SCX114-9R6.

Packaging: The CTX10-1P-R is supplied in Tape & Reel (TR) format, supporting automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the CTX10-1P-R be used as a direct replacement for the SCX114-9R6?

A: Yes. The CTX10-1P-R meets all electrical specifications and mechanical requirements. The inductance values, current ratings, and DC resistance parameters are equivalent within the defined tolerances. Both components are unshielded, 2-coil surface mount inductors with identical functional characteristics.

Q: What are the differences between these two parts?

A: The primary differences are manufacturer, product status, and physical dimensions. The CTX10-1P-R is manufactured by Eaton and is in active production, whereas the SCX114-9R6 is obsolete. The CTX10-1P-R has a slightly smaller footprint and lower profile, which may provide layout advantages in space-constrained applications.

Q: Are there any compatibility concerns with the smaller footprint of the CTX10-1P-R?

A: No. The CTX10-1P-R footprint (0.450" x 0.450") is smaller than the SCX114-9R6 (0.461" x 0.461"), making it compatible with existing PCB layouts designed for the original part. The lower height (0.165" versus 0.217") also provides clearance benefits.

Q: Do both parts have the same inductance tolerance?

A: Yes. Both the SCX114-9R6 and CTX10-1P-R have ±20% inductance tolerance. The parallel inductance values (9.6 µH and 9.62 µH respectively) fall within this tolerance band and are functionally equivalent.

Q: What is the operating temperature range for the CTX10-1P-R?

A: The CTX10-1P-R operates across -40°C to 85°C. This temperature range supports standard industrial and commercial applications.

Q: Are both parts RoHS compliant?

A: Yes. Both the SCX114-9R6 and CTX10-1P-R are ROHS3 compliant and have MSL Level 1 rating, meeting current environmental and reliability standards.
