Key Parameters

Substitute Part Grouping Explanation

The 165V18 qualifies as a direct substitute based on the following critical parameters:

• Identical primary voltage: 115V
• Identical secondary voltage: 18V with center tap
• Identical maximum output current: 20A
• Identical power rating: 360VA
• Identical core type: Laminated
• Identical winding configuration: Single primary, single secondary
• Identical mounting type: Chassis Mount
• Identical termination style: Wire Leads
• Identical isolation voltage: 2000Vrms
• Identical RoHS compliance: ROHS3 Compliant

The 165V18 is active in production, addressing the obsolescence of the 167V18 while maintaining full electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The 165V18 is the direct equivalent for the obsolete 167V18. Both transformers share identical electrical specifications, core construction, and compliance certifications. The 165V18 is currently in active production with confirmed inventory availability.

Physical dimensions differ slightly between the two models. The 165V18 has a reduced height profile (95.25mm versus 115.82mm) and different length and width measurements. Verify mounting clearances in the target application before implementation.

Both parts maintain ROHS3 compliance and identical isolation voltage ratings, supporting equivalent performance in regulated environments.

Frequently Asked Questions (FAQ)

Q: Can the 165V18 directly replace the 167V18 in existing designs?

A: Yes, the 165V18 provides electrical equivalence across all critical parameters: primary voltage, secondary voltage, current rating, power capacity, winding configuration, and isolation voltage. Physical dimensions differ, requiring verification of mounting space availability.

Q: Are there compliance differences between the 167V18 and 165V18?

A: No. Both transformers are ROHS3 compliant with identical isolation voltage specifications (2000Vrms). Compliance certifications are equivalent.

Q: What are the dimensional differences between these parts?

A: The 167V18 measures 95.25mm L x 114.30mm W x 115.82mm H (seated), while the 165V18 measures 114.30mm L x 101.60mm W x 95.25mm H (seated). The 165V18 is shorter but has different length and width proportions. Confirm available mounting space before substitution.

Q: Do both transformers have center-tapped secondaries?

A: Yes. Both the 167V18 and 165V18 feature single center-tapped secondary windings rated at 18V, supporting identical circuit configurations.

Q: What is the weight difference?

A: The 167V18 weighs 12 lbs (5.4 kg), while the 165V18 weighs 11 lbs (5 kg). The difference reflects the dimensional variation between models.
