Substitute Part Grouping Explanation

The TP02190A-4K is identified as the direct manufacturer substitute for the obsolete TP01190A-4K. Substitution eligibility is determined by the following critical parameters:

• Diagonal Screen Size: Both parts maintain 19.00" (482.60mm) specification
• Touch Technology: Both utilize resistive touch screen overlay technology
• Physical Dimensions: Length (15.04" / 382.00mm) and overall form factor are preserved
• Compliance Standards: Both meet RoHS requirements (TP01 is ROHS3 Compliant; TP02 is RoHS Compliant)
• Moisture Sensitivity: Both rated MSL 1 (Unlimited)

The TP02190A-4K represents the active production equivalent within the NKK Switches touch screen overlay product line, ensuring functional and dimensional compatibility for applications currently utilizing the TP01190A-4K.

Parameter Comparison

Engineering Selection Recommendations

The TP02190A-4K is the designated active production substitute for the obsolete TP01190A-4K. Selection of the TP02190A-4K is appropriate for new designs and ongoing production requirements due to its active product status and confirmed availability. Both parts maintain identical screen size (19 inches), resistive touch technology, and critical physical dimensions. The TP02190A-4K carries current RoHS compliance certification and equivalent moisture sensitivity ratings, supporting long-term supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the TP02190A-4K directly replace the TP01190A-4K in existing applications?

A: Yes. Both parts share identical diagonal screen size (19 inches), resistive touch screen technology, and matching physical dimensions (length 15.04", height 12.10"). The TP02190A-4K is the active production equivalent designated by NKK Switches.

Q: What is the primary reason for substitution?

A: The TP01190A-4K is classified as obsolete and no longer in active production. The TP02190A-4K represents the current active product line equivalent, ensuring ongoing component availability and supply chain stability.

Q: Are there compliance differences between the two parts?

A: Both parts meet RoHS environmental compliance standards. The TP01190A-4K is ROHS3 Compliant, while the TP02190A-4K is RoHS Compliant. Both maintain MSL 1 (Unlimited) moisture sensitivity ratings.

Q: What is the interface specification for these parts?

A: The TP01190A-4K specifies a 4-Wire interface. The TP02190A-4K does not list interface specification in available documentation but maintains functional equivalence as the designated manufacturer substitute.
