EYP-2BH134 Equivalent & Substitute Parts

Part Overview

The EYP-2BH134 is a Thermal Cutoff (TCO) device manufactured by Panasonic Electronic Components, rated for 250VAC/50VDC operation at 134°C (273°F) functioning temperature with radial 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 eligibility for the EYP-2BH134 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 134°C (273°F)
• Holding Temperature: Substitute must maintain thermal stability at or above 95°C (203°F)
• Package Type: Radial configuration required for mechanical compatibility
• Product Type: Thermal Cutoff (TCO) fuse classification

The MTS1 S125 manufactured by Cantherm meets these substitution criteria with equivalent voltage ratings, compatible radial packaging, and functioning temperature within acceptable operational range.

Parameter Comparison

Engineering Selection Recommendations

The MTS1 S125 serves as an active substitute for the obsolete EYP-2BH134. Both components share identical 250VAC voltage ratings and radial packaging configuration. The MTS1 S125 maintains a functioning temperature of 130°C, which is 4°C below the original specification of 134°C, and a holding temperature of 100°C, which exceeds the original 95°C requirement. The substitute component is currently in active production status with ROHS3 compliance certification, supporting long-term availability and regulatory alignment for new implementations.

Frequently Asked Questions (FAQ)

Q: Can the MTS1 S125 directly replace the EYP-2BH134 in existing applications?

A: The MTS1 S125 is mechanically and electrically compatible based on shared radial packaging, identical 250VAC rating, and comparable thermal operating parameters. The 4°C difference in functioning temperature (130°C vs. 134°C) represents a minor deviation within typical thermal tolerance ranges for TCO devices.

Q: What is the significance of the functioning temperature difference?

A: The EYP-2BH134 functions at 134°C while the MTS1 S125 functions at 130°C. This 4°C difference means the substitute will activate thermal cutoff protection at a slightly lower temperature threshold. Applications with tight thermal margins should evaluate this parameter against system requirements.

Q: Why is the EYP-2BH134 listed as obsolete?

A: Obsolete status indicates the component is no longer manufactured by Panasonic Electronic Components. The MTS1 S125 is an active production alternative from Cantherm, ensuring continued availability for replacement and new design applications.

Q: Are there compliance differences between the two parts?

A: The EYP-2BH134 carries multiple approval certifications (BEAB, CCC, CSA, cUL, PSE, UL, VDE). The MTS1 S125 approval status is not specified in available documentation. Applications requiring specific regulatory certifications should verify compliance requirements independently.

Q: What is the current rating specification for these components?

A: The MTS1 S125 is rated for 5A current capacity. The current rating for the EYP-2BH134 is not specified in available documentation. Current handling capability should be evaluated against application requirements.
