TP01104A-4K Resistive Touch Screen Overlay - Equivalent & Substitute Parts

Part Overview

The TP01104A-4K is a resistive touch screen overlay manufactured by NKK Switches with a 10.4-inch diagonal screen size and 4-wire interface configuration. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing system support and component procurement.

The transition from the TP01 series to the TP02 series represents the manufacturer's product line evolution. Substitute parts must maintain compatibility across critical electrical and mechanical parameters to ensure functional equivalence in applications requiring resistive touch screen overlay technology.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the TP01104A-4K is determined by strict alignment of the following critical parameters:

• Diagonal Screen Size: 10.4" (264.16mm) — exact match required
• Touch Technology: Resistive — no alternative technologies acceptable
• RoHS Compliance: ROHS3 Compliant — regulatory requirement maintained
• Moisture Sensitivity Level: 1 (Unlimited) — environmental tolerance equivalent

The TP02104A-4K qualifies as a direct substitute based on matching all critical parameters. The transition from the TP01 series to the TP02 series represents a product line refresh by NKK Switches while maintaining core electrical and mechanical specifications for 10.4-inch resistive touch screen overlay applications.

Engineering Selection Recommendations

The TP02104A-4K is the designated substitute for the obsolete TP01104A-4K. Selection is based on the following engineering criteria:

• Both parts maintain ROHS3 compliance, satisfying regulatory requirements for new designs and replacements
• Identical moisture sensitivity level (MSL 1) ensures equivalent environmental performance
• Matching screen size (10.4 inches) and resistive touch technology preserve functional compatibility
• The TP02104A-4K carries active product status, ensuring ongoing manufacturer support and availability
• The TP02104A-4K includes REACH compliance documentation and EAR99 export classification, providing additional regulatory clarity for international applications

Frequently Asked Questions (FAQ)

Q: Can the TP02104A-4K replace the TP01104A-4K in existing applications?

A: Yes. Both parts share identical diagonal screen size (10.4 inches), resistive touch technology, and environmental specifications (MSL 1). The TP02104A-4K is the manufacturer's designated successor in the product line.

Q: What is the significance of the width and height dimension differences shown in the parameter comparison?

A: The dimensional differences between the two parts reflect how the manufacturer specifies overlay dimensions. Both parts are designed for 10.4-inch screen applications. Physical mounting compatibility should be verified against your specific application requirements and mechanical drawings.

Q: Does the TP02104A-4K maintain the same 4-wire interface as the TP01104A-4K?

A: The TP01104A-4K specifies a 4-wire interface. The TP02104A-4K does not list interface specification in the provided data. Interface compatibility must be confirmed through detailed technical documentation or direct consultation with NKK Switches before implementation.

Q: Are there any compliance advantages to using the TP02104A-4K?

A: The TP02104A-4K includes REACH compliance status and EAR99 export classification documentation, providing additional regulatory transparency. Both parts maintain ROHS3 compliance.

Q: What packaging is available for the TP02104A-4K?

A: The TP02104A-4K is supplied in box packaging, compared to the TP01104A-4K which does not specify packaging format in the provided data.
