CTX10-2P Equivalent & Substitute Parts

Part Overview

The CTX10-2P is an unshielded 2-coil inductor array manufactured by Eaton - Electronics Division under the Econo-Pac™ series. This surface mount component provides dual inductance configurations: 39.3 µH when coils are connected in series and 9.83 µH when connected in parallel. The part is classified as obsolete, which necessitates identification of active equivalent alternatives for ongoing procurement and design continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the CTX10-2P is determined by strict equivalence across the following electrical and mechanical parameters:

Electrical Equivalence Criteria:

• Inductance values in both series (39.3 µH) and parallel (9.83 µH) configurations must match exactly
• Tolerance specification (±20%) must be maintained
• Current ratings for both configurations (2.1 A parallel, 1.05 A series) must be met or exceeded
• DC resistance specifications (45 mOhm max parallel, 179 mOhm max series) must be met or exceeded
• Operating temperature range (-40°C to 85°C) must be supported
• Number of coils (2) must be identical

Mechanical Equivalence Criteria:

• Surface mount mounting type required
• Physical dimensions (0.450" x 0.450" x 0.235") must be identical
• Nonstandard package classification must match
• Unshielded configuration required

The CTX10-2P-R satisfies all electrical and mechanical equivalence criteria and is therefore a direct substitute.

Engineering Selection Recommendations

The CTX10-2P-R is the direct electrical and mechanical equivalent of the CTX10-2P. Selection of the CTX10-2P-R is appropriate for the following reasons:

Product Status: The CTX10-2P is classified as obsolete. The CTX10-2P-R maintains active product status with Eaton - Electronics Division, ensuring continued availability and supply chain reliability.

Electrical Compatibility: All electrical parameters are identical between the two parts. The CTX10-2P-R will function identically in series and parallel configurations with matching inductance values, current ratings, and DC resistance specifications.

Mechanical Compatibility: Physical dimensions, mounting type, and package classification are identical. The CTX10-2P-R is a direct footprint replacement.

Compliance Enhancement: The CTX10-2P-R is ROHS3 compliant, whereas the original CTX10-2P is RoHS non-compliant. This represents an improvement in regulatory compliance for new designs or redesigns.

Packaging Consideration: The CTX10-2P-R is supplied in Tape & Reel (TR) format, which differs from the bulk packaging of the original part. This packaging format is standard for high-volume manufacturing and automated assembly processes.

Frequently Asked Questions (FAQ)

Q: Can the CTX10-2P-R be used as a direct replacement for the CTX10-2P in existing designs?

A: Yes. The CTX10-2P-R is electrically and mechanically identical to the CTX10-2P. All inductance values, current ratings, DC resistance specifications, operating temperature range, and physical dimensions match exactly. The part will function identically in both series and parallel coil configurations.

Q: What is the difference between the CTX10-2P and CTX10-2P-R?

A: The primary differences are product status and packaging format. The CTX10-2P is obsolete and supplied in bulk packaging. The CTX10-2P-R is an active product supplied in Tape & Reel (TR) format. Additionally, the CTX10-2P-R is ROHS3 compliant, while the original part is RoHS non-compliant. All electrical and mechanical specifications are identical.

Q: Does the Tape & Reel packaging of the CTX10-2P-R affect compatibility?

A: No. Tape & Reel packaging is a supply format used for automated assembly and does not affect the electrical or mechanical performance of the component. The physical part itself is identical to the bulk-packaged version.

Q: Are there any thermal or frequency limitations I should consider when substituting the CTX10-2P-R?

A: The operating temperature range for both parts is -40°C to 85°C. No frequency-dependent parameters are specified in the component data. Use the CTX10-2P-R within the specified temperature range for your application.

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

A: The ±20% tolerance applies to the inductance values in both series and parallel configurations. This means the actual inductance may vary by up to 20% from the nominal values of 39.3 µH (series) and 9.83 µH (parallel). Both the CTX10-2P and CTX10-2P-R share this tolerance specification.

Q: Can I use the CTX10-2P-R in applications requiring RoHS compliance?

A: Yes. The CTX10-2P-R is ROHS3 compliant, making it suitable for applications with RoHS compliance requirements. The original CTX10-2P is RoHS non-compliant and would not be suitable for such applications.
