Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HTW-00-RED is determined by strict alignment with the following critical parameters:

• Actuator Type & Function: Thumbwheel, 1-axis, 2-way directional operation
• Output Technology: Analog Hall Effect output
• Supply Voltage: 5VDC operation
• Mechanical Interface: Panel mount with wire lead termination
• Physical Compatibility: Panel cutout dimensions of 36.45mm x 16.05mm
• Environmental Compliance: ROHS3 compliance and operating temperature range of -40°C to 85°C
• Mechanical Durability: 5,000,000 cycle mechanical life rating

The substitute part TW01RED13 maintains functional equivalence across all critical parameters while offering enhanced environmental protection and active product status.

Parameter Comparison

Engineering Selection Recommendations

The TW01RED13 serves as a direct functional substitute for the obsolete HTW-00-RED. Both components share identical core specifications for actuator type, output technology, supply voltage, mechanical interface, and environmental operating range. The substitute part offers the additional advantage of active product status, ensuring continued availability and supply chain reliability.

The TW01RED13 incorporates IP67 ingress protection, providing enhanced environmental sealing compared to the HTW-00-RED. The operating force differential of 9gf (71gf versus 80gf) represents a minor mechanical variation within typical application tolerances for thumbwheel switches.

ROHS3 compliance is maintained across both components, supporting regulatory requirements for electronic equipment manufacturing and distribution.

Frequently Asked Questions (FAQ)

Q: Can TW01RED13 replace HTW-00-RED in existing applications?

A: Yes. Both components share identical specifications for actuator type, Hall Effect output, 5VDC supply voltage, panel mount interface, wire lead termination, operating temperature range, and mechanical life rating. Physical panel cutout dimensions are identical at 36.45mm x 16.05mm.

Q: What is the significance of the operating force difference?

A: The HTW-00-RED operates at 80gf while the TW01RED13 operates at 71gf. This 9gf difference represents a minor variation in the mechanical actuation force required. Application compatibility depends on specific force requirements of the end system.

Q: Why does TW01RED13 have IP67 rating while HTW-00-RED does not?

A: The TW01RED13 incorporates enhanced environmental sealing. This additional protection does not affect electrical or mechanical compatibility and provides improved performance in applications exposed to dust or moisture.

Q: Are both parts ROHS3 compliant?

A: Yes. Both HTW-00-RED and TW01RED13 meet ROHS3 compliance requirements.

Q: What is the packaging difference?

A: HTW-00-RED is supplied with standard packaging, while TW01RED13 is supplied in bulk packaging. Both contain identical components.

Q: Is TW01RED13 currently available?

A: Yes. TW01RED13 maintains active product status with 772 pieces in stock, compared to the obsolete HTW-00-RED status.
