Parameter Comparison

Engineering Selection Recommendations

Both P6SMB110A and TVP06B111A-G are qualified substitutes for the obsolete P6SMBJ110. Selection between these alternatives is based on the following factors:

P6SMB110A (Eaton - Electronics Division): This substitute maintains exact electrical specifications with 4A peak pulse current and is classified as an active product with established supply chain availability. RoHS compliance is confirmed. This part is suitable for applications requiring maximum parameter alignment with the original design.

TVP06B111A-G (Comchip Technology): This substitute operates within specified electrical tolerances with 3.95A peak pulse current and is classified as an active product. ROHS3 compliance and REACH unaffected status are confirmed. This part is suitable for applications where minor current variations are acceptable within system design margins.

Both substitutes share identical package geometry, thermal operating range, and power dissipation ratings, ensuring direct mechanical and thermal compatibility in existing PCB layouts.

Frequently Asked Questions (FAQ)

Q: Can P6SMB110A and TVP06B111A-G be used interchangeably with P6SMBJ110?

A: Both parts meet the critical electrical parameters of the P6SMBJ110 within specified tolerances. Direct substitution is supported for applications where the clamping voltage range of 152V and peak pulse current of 3.95A–4A are acceptable. Circuit validation is required to confirm compatibility with specific system voltage and transient profiles.

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

A: The P6SMB110A maintains exact 4A peak pulse current specification, while TVP06B111A-G operates at 3.95A. Both achieve identical 152V clamping voltage and 600W power dissipation. The difference is negligible for most general-purpose transient suppression applications.

Q: Are the substitute parts available in the same package?

A: Yes. Both P6SMB110A and TVP06B111A-G are supplied in DO-214AA (SMB) surface-mount packages, identical to the original P6SMBJ110. PCB footprints and reflow soldering processes require no modification.

Q: What compliance certifications apply to the substitute parts?

A: P6SMB110A is RoHS compliant. TVP06B111A-G is ROHS3 compliant and REACH unaffected. Both parts carry MSL 1 (Unlimited) moisture sensitivity ratings. All parts are classified under ECCN EAR99 and HTSUS 8541.10.0080.

Q: Why is the P6SMBJ110 listed as obsolete?

A: The P6SMBJ110 is no longer in active production by Littelfuse Inc. The substitute parts listed represent current manufacturing alternatives that satisfy the electrical and mechanical requirements of the original design.
