EYP-2BN134 Equivalent & Substitute Parts

Part Overview

The EYP-2BN134 is a Thermal Cutoff (TCO) device manufactured by Panasonic Electronic Components, rated for 250VAC/50VDC operation at 139°C (282°F) functioning temperature with axial packaging. This component is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing system maintenance and new design implementations where legacy specifications must be maintained.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the EYP-2BN134 is determined by the following critical parameters:

• Voltage Rating (AC/DC): Substitute must support minimum 250VAC and 50VDC
• Rated Functioning Temperature: Substitute must operate at or above 139°C (282°F)
• Holding Temperature: Substitute must maintain holding temperature at or above 110°C (230°F)
• Package Type: Substitute must use axial configuration for mechanical compatibility
• Approval Certifications: Substitute should maintain compliance with primary regulatory bodies (UL, cUL, VDE, PSE, CCC)

The SDF DF141S from Cantherm meets these substitution criteria with a functioning temperature of 141°C (286°F), holding temperature of 117°C (243°F), and identical 250VAC voltage rating, all within axial packaging.

Parameter Comparison

Engineering Selection Recommendations

The SDF DF141S is the identified equivalent substitute for the obsolete EYP-2BN134 based on matching voltage ratings, compatible thermal operating parameters, and identical axial packaging. The substitute's higher functioning temperature (141°C vs. 139°C) and holding temperature (117°C vs. 110°C) provide operational margin within the same thermal class.

The SDF DF141S maintains active product status with current manufacturing availability, addressing the obsolescence constraint of the original component. Regulatory compliance includes UL, cUL, VDE, PSE, and CCC certifications, covering primary international markets. The absence of BEAB and CSA certifications on the substitute should be evaluated against specific regional requirements.

Frequently Asked Questions (FAQ)

Q: Can the SDF DF141S directly replace the EYP-2BN134 in existing designs?

A: The SDF DF141S is mechanically and electrically compatible for AC applications at 250VAC. Axial packaging is identical. For DC applications, the DC voltage rating of the SDF DF141S must be confirmed with the manufacturer, as this parameter is not provided in available documentation.

Q: What is the significance of the higher functioning temperature on the substitute?

A: The SDF DF141S operates at 141°C versus the original 139°C. This represents a 2°C higher threshold and does not compromise compatibility. The substitute will trigger thermal cutoff at a slightly higher temperature, which is acceptable for applications designed around the original 139°C specification.

Q: Are there regulatory compliance differences between the two parts?

A: Both parts carry UL, cUL, VDE, PSE, and CCC certifications. The original EYP-2BN134 includes additional BEAB and CSA approvals. If these specific certifications are required for your application, compatibility must be confirmed with your regulatory or procurement team.

Q: What is the current rating difference, and does it matter?

A: The SDF DF141S specifies a 10A current rating, while the original part does not provide this parameter. Verify that your circuit current requirements do not exceed 10A. If the original design operates below this threshold, the substitute is suitable.

Q: Is the SDF DF141S available in the same packaging format?

A: Yes, both components use axial packaging. The SDF DF141S is supplied in bulk packaging, whereas original availability information for the EYP-2BN134 is not specified. Confirm packaging and quantity requirements with your supplier.
