HA1B-V2E1R Equivalent & Substitute Parts

Part Overview

The HA1B-V2E1R is a 16mm panel-mount emergency stop switch manufactured by IDEC, classified as SPST-NC (Single Pole Single Throw - Normally Closed) with twist reset operation. This component is designed for on-off switching applications requiring dust-tight and water-resistant enclosure protection. The part is currently obsolete, necessitating identification of functionally equivalent active alternatives that maintain compatibility with existing panel cutout dimensions and electrical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HA1B-V2E1R is determined by the following critical parameters:

Mechanical Compatibility:

• Panel cutout dimensions must be circular 16.20mm diameter to fit existing panel installations
• Mounting type must be panel mount, front configuration
• Termination style must be solder or quick connect 0.110" (2.8mm) to maintain wiring compatibility

Electrical Compatibility:

• Circuit configuration must be SPST-NC to preserve normally-closed safety function
• Switch function must be on-off operation
• Voltage ratings must meet or exceed 125V AC and 30V DC minimum requirements
• Current ratings must support the application load requirements

Environmental Compatibility:

• Ingress protection must be IP65 or higher
• Operating temperature range must encompass the application environment

Regulatory Compliance:

• RoHS3 compliance required for environmental standards adherence

The substitute parts identified maintain these critical parameters while offering active product status and enhanced operational characteristics.

Engineering Selection Recommendations

AB6E-3BV01PTRH Selection Criteria:

The AB6E-3BV01PTRH maintains full electrical and mechanical compatibility with the HA1B-V2E1R across all critical parameters. This substitute provides equivalent AC current rating (5A) and identical voltage specifications. The extended operating temperature range (-25°C ~ 60°C) offers improved thermal performance. Reset operation flexibility (pull or twist) accommodates both original twist-only applications and enhanced operational modes. Active product status ensures ongoing availability and supply chain continuity. ROHS3 compliance and REACH unaffected designation confirm regulatory alignment.

XA1E-BV3U01T-R Selection Criteria:

The XA1E-BV3U01T-R provides functional substitution with identical mechanical mounting and electrical circuit configuration. This unibody design variant maintains SPST-NC operation and voltage ratings. DC current rating reduction (2A versus 3A) and AC current rating reduction (3A versus 5A) require application load verification. Extended operating temperature range (-25°C ~ 60°C) and active product status support long-term deployment. ROHS3 compliance and REACH unaffected designation confirm regulatory requirements. Selection of this part is appropriate for applications with current requirements not exceeding 3A AC or 2A DC.

Frequently Asked Questions (FAQ)

Q: Can the AB6E-3BV01PTRH directly replace the HA1B-V2E1R in existing installations?

A: Yes. The AB6E-3BV01PTRH maintains identical panel cutout dimensions (16.20mm circular), termination style (0.110" quick connect), and electrical circuit configuration (SPST-NC). No panel modifications or wiring changes are required. The part is a direct mechanical and electrical substitute.

Q: What is the primary difference between the two substitute options?

A: The AB6E-3BV01PTRH maintains the original 5A AC current rating, while the XA1E-BV3U01T-R reduces AC current capacity to 3A. Both maintain 125V AC and 30V DC voltage ratings. Selection depends on application current requirements.

Q: Are both substitute parts suitable for the same operating temperature range as the original?

A: Both substitute parts extend the operating temperature range to -25°C ~ 60°C, compared to the original -25°C ~ 55°C specification. This represents improved thermal performance and broader environmental compatibility.

Q: Do the substitute parts maintain the same reset operation as the original HA1B-V2E1R?

A: The original HA1B-V2E1R features twist-only reset operation. Both substitute parts support pull or twist reset operation, providing operational flexibility while maintaining compatibility with twist-only applications.

Q: What is the significance of the active product status for the substitute parts?

A: Active product status indicates ongoing manufacturing and supply availability. The HA1B-V2E1R is obsolete, meaning production has ceased and inventory is limited. Substitutes with active status ensure long-term component availability for future production runs and field replacements.

Q: Are there any compliance differences between the main part and substitutes?

A: All three parts maintain ROHS3 compliance. The substitute parts include additional REACH unaffected designation and ECCN classification (EAR99), confirming regulatory alignment with current export and environmental standards.

Q: Can the XA1E-BV3U01T-R be used in applications requiring 5A AC current?

A: No. The XA1E-BV3U01T-R is rated for 3A AC maximum. Applications requiring 5A AC current must use the AB6E-3BV01PTRH or verify that actual load current does not exceed 3A.
