Parameter Comparison

Engineering Selection Recommendations

Primary Substitute: CTX20-2-R

The CTX20-2-R is the direct functional equivalent of the CTX20-2. All electrical specifications, mechanical dimensions, and performance parameters are identical. The CTX20-2-R is the appropriate selection for new designs and ongoing production support.

Compliance Considerations:

The CTX20-2-R carries Active product status, ensuring continued manufacturer support and supply chain availability. The CTX20-2-R meets ROHS3 compliance requirements, whereas the original CTX20-2 is RoHS non-compliant. For applications subject to RoHS regulatory requirements, the CTX20-2-R is the mandated selection.

Packaging Consideration:

The CTX20-2-R is supplied in Tape & Reel (TR) format, which is standard for high-volume surface mount assembly operations. The original CTX20-2 packaging format is not specified in available documentation. Tape & Reel packaging is compatible with automated pick-and-place assembly equipment.

Supply Chain Status:

The CTX20-2-R maintains current inventory availability (2316 pieces in stock) with Active product status. The CTX20-2 is classified as Obsolete with limited remaining inventory (1142 pieces). For new production commitments, the CTX20-2-R is the appropriate selection to ensure supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the CTX20-2-R be used as a direct replacement for the CTX20-2 in existing designs?

A: Yes. The CTX20-2-R is electrically and mechanically identical to the CTX20-2.
