HA1B-V2E2R Emergency Stop Switch - Equivalent & Substitute Parts

Part Overview

The HA1B-V2E2R is a 16mm emergency stop switch manufactured by IDEC, designed for panel mount applications with front access. This component features a twist reset operation, DPST-NC circuit configuration, and IP65 ingress protection rating. The part is classified as obsolete, making identification of equivalent substitute components necessary for ongoing maintenance, repair, and new design implementations where this functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the HA1B-V2E2R is determined by the following critical parameters:

• Mounting Configuration: Panel mount, front access orientation
• Circuit Type: DPST-NC (Double Pole, Single Throw, Normally Closed)
• Switch Function: On-Off operation
• Panel Cutout Compatibility: Circular aperture, nominally 16mm diameter
• Ingress Protection: IP65 rating minimum
• Regulatory Compliance: ROHS3 compliance and EAR99 classification

The three substitute parts listed below satisfy these core functional and mechanical requirements. Variations in reset operation (twist versus pull-or-twist), termination style (solder lug versus quick connect), and electrical ratings represent acceptable design alternatives within the emergency stop switch category.

Parameter Comparison

Engineering Selection Recommendations

All three substitute parts are manufactured by IDEC and maintain active product status, ensuring ongoing availability and supply chain continuity. Each substitute meets ROHS3 compliance and EAR99 classification requirements consistent with the original HA1B-V2E2R.

XA1E-BV302-R provides the closest functional match to the original part, retaining twist-only reset operation and solder lug termination. This configuration minimizes design modifications in existing installations.

AB6E-3BV02PTRH and XA1E-BV3U02T-R both offer pull-or-twist reset operation and dual termination options (solder and quick connect). These alternatives provide operational flexibility and may simplify field maintenance procedures. The quick connect termination option reduces installation time compared to solder lug configurations.

Panel cutout dimensions for all substitutes are 16.20mm diameter, representing a 0.20mm increase from the original 16.00mm specification. This minor dimensional variance is within standard mechanical tolerances for panel mount emergency stop switches and does not preclude direct substitution in existing panel apertures.

Frequently Asked Questions (FAQ)

Q: Can the HA1B-V2E2R be directly replaced with any of these substitute parts?

A: Yes. All three substitute parts satisfy the core functional requirements: DPST-NC circuit configuration, panel mount front access, IP65 ingress protection, and ROHS3 compliance. Panel cutout dimensions are compatible within standard mechanical tolerances.

Q: What is the difference between twist and pull-or-twist reset operations?

A: The original HA1B-V2E2R requires twist motion for reset. Substitutes XA1E-BV302-R maintains this twist-only operation. AB6E-3BV02PTRH and XA1E-BV3U02T-R accept either pull or twist motion, providing operational flexibility without requiring design changes.

Q: Are there electrical rating differences between the main part and substitutes?

A: The original HA1B-V2E2R does not specify current or voltage ratings in the provided data. Substitute parts are rated at 3A (AC) or 5A (AC) and 2A (DC), with voltage ratings of 125V AC and 30V DC. These ratings are standard for 16mm emergency stop switches and support typical industrial control applications.

Q: What is the significance of the termination style options?

A: The original part uses solder lug termination. XA1E-BV302-R maintains this configuration. AB6E-3BV02PTRH and XA1E-BV3U02T-R offer both solder and quick connect (0.110" / 2.8mm) termination, allowing selection based on installation method and maintenance requirements.

Q: Are all substitutes currently available?

A: Yes. All three substitute parts maintain active product status with documented inventory levels: AB6E-3BV02PTRH (1156 units), XA1E-BV302-R (1024 units), and XA1E-BV3U02T-R (864 units).

Q: Do the substitutes meet the same compliance standards?

A: Yes. All substitute parts are ROHS3 compliant and classified as EAR99, matching the regulatory profile of the original HA1B-V2E2R.
