QT01201 Equivalent & Substitute Parts

Part Overview

The TE Connectivity ALCOSWITCH QT01201 is a configurable switch body component featuring a rectangular dual pushbutton actuator in non-illuminated configuration. This component is classified as obsolete, requiring identification of active equivalent alternatives for ongoing production and maintenance applications. The QT01201 operates as a momentary-type switch and necessitates compatible contact block assemblies for complete functionality. Due to its obsolete status, substitute parts from active product lines are required to ensure supply chain continuity and component availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the QT01201 is determined by the following critical parameters: switch type (momentary operation), illumination requirement (non-illuminated), actuator geometry (pushbutton configuration), and panel cutout compatibility (22.2mm to 22.3mm round dimensions). The QT01201 accepts contact block assemblies as modular components, allowing functional equivalence through compatible switch body platforms.

Substitute parts are grouped into two functional categories:

Non-Illuminated Pushbutton Bodies: Parts 1.30.240.121/0400, 1.30.240.121/0500, and 1.30.240.121/0300 provide direct functional equivalence to the QT01201 as non-illuminated momentary pushbutton switch bodies. These components maintain identical operational characteristics while offering active product status and enhanced compliance certifications.

Illuminated Pushbutton Bodies: Parts 1.30.240.021/1000, 1.30.240.021/1300, 1.30.240.021/1400, and 1.30.240.021/1500 represent alternative configurations with integrated illumination capability. These parts maintain momentary operation and pushbutton actuator type but require illumination source assemblies in addition to contact blocks.

All substitute parts are manufactured by RAFI USA within the RAFIX 22 QR series, feature panel cutout dimensions of 22.3mm (Round), and operate as momentary-type configurable switch components.

Engineering Selection Recommendations

For applications requiring direct functional replacement of the obsolete QT01201 without illumination capability, the RAFI USA non-illuminated pushbutton bodies 1.30.240.121/0400, 1.30.240.121/0500, and 1.30.240.121/0300 are the primary substitutes. These components maintain momentary operation, non-illuminated configuration, and contact block modularity. All three parts carry active product status and ROHS3 compliance certification, providing superior regulatory alignment compared to the obsolete QT01201.

For applications where illumination functionality is required or beneficial, the RAFI USA illuminated pushbutton bodies 1.30.240.021/1000 (White), 1.30.240.021/1300 (Red), 1.30.240.021/1400 (Yellow), and 1.30.240.021/1500 (Green) provide equivalent momentary operation with integrated illumination options. These parts require illumination source assemblies in addition to contact blocks but offer active product status and ROHS3 compliance.

All substitute parts feature panel cutout dimensions of 22.3mm (Round), which accommodates the 22.2mm (Round) specification of the QT01201 within standard mechanical tolerances for panel-mounted switch installations. All substitute components maintain REACH Unaffected and EAR99 export classification status consistent with the original part.

Frequently Asked Questions (FAQ)

Q: Can the RAFI USA RAFIX 22 QR series parts directly replace the TE Connectivity QT01201?

A: Yes. The RAFI USA parts maintain equivalent momentary operation, pushbutton actuator configuration, and contact block modularity. Panel cutout dimensions of 22.3mm (Round) accommodate the QT01201 specification of 22.2mm (Round) within standard mechanical tolerances for panel installations.

Q: What is the primary difference between non-illuminated and illuminated substitute options?

A: Non-illuminated parts (1.30.240.121/0400, 1.30.240.121/0500, 1.30.240.121/0300) require only contact block assemblies for operation. Illuminated parts (1.30.240.021/1000, 1.30.240.021/1300, 1.30.240.021/1400, 1.30.240.021/1500) require both contact block and illumination source assemblies. Illuminated variants offer color options: White, Red, Yellow, and Green.

Q: Are all substitute parts actively manufactured?

A: Yes. All RAFI USA substitute parts carry active product status, ensuring ongoing availability and supply chain continuity. The original QT01201 is classified as obsolete.

Q: What compliance certifications do the substitute parts provide?

A: All RAFI USA substitute parts are ROHS3 compliant and REACH Unaffected. The original QT01201 does not specify RoHS status. All parts maintain EAR99 export classification.

Q: What is the Moisture Sensitivity Level (MSL) for substitute parts?

A: All RAFI USA substitute parts carry MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage and handling. The original QT01201 specifies MSL as Not Applicable.

Q: Are the actuator shapes identical between the QT01201 and substitute parts?

A: The QT01201 features a rectangular dual pushbutton actuator, while all RAFI USA substitute parts feature round pushbutton actuators. Both configurations operate as momentary switches and accept compatible contact block assemblies. Panel cutout dimensions remain compatible within standard mechanical tolerances.

Q: What contact block options are compatible with substitute parts?

A: Substitute parts require contact block assemblies as modular components. Specific contact block compatibility is determined by the RAFIX 22 QR series platform. Contact block selection depends on electrical switching requirements and circuit configuration.

Q: Can illuminated substitute parts be used in applications where illumination is not required?

A: Illuminated parts can be installed without illumination sources, functioning as non-illuminated switches. However, non-illuminated parts (1.30.240.121/0400, 1.30.240.121/0500, 1.30.240.121/0300) are the appropriate selection for applications without illumination requirements, as they eliminate unnecessary component complexity and cost.
