Hammond Manufacturing 167S18 Equivalent & Substitute Parts

Part Overview

The Hammond Manufacturing 167S18 is a laminated core power transformer rated for 180VA with a 115V primary and 18V secondary output. This chassis-mounted transformer features a center tap configuration and wire lead termination, designed for industrial and commercial power conversion applications. The 167S18 is classified as obsolete, making identification of compatible substitute components essential for ongoing system maintenance and new design implementations. The 165S18 represents the active production equivalent within Hammond's transformer portfolio.

Key Parameters

Substitute Part Grouping Explanation

The 165S18 qualifies as a direct substitute for the 167S18 based on the following critical parameters:

• Identical primary voltage: 115V
• Identical secondary voltage: 18V
• Identical maximum output current: 10A
• Identical power rating: 180VA
• Identical core type: Laminated
• Identical winding configuration: Single primary, single secondary with center tap
• Identical mounting type: Chassis Mount
• Identical termination style: Wire Leads
• Identical isolation voltage: 2000Vrms
• Identical RoHS3 compliance status
• Identical REACH unaffected status

The 165S18 differs from the 167S18 only in physical dimensions and product status. The 165S18 is currently in active production, whereas the 167S18 is obsolete.

Parameter Comparison

Engineering Selection Recommendations

The 165S18 is the appropriate substitute for the obsolete 167S18 transformer. Both components maintain identical electrical specifications, winding configurations, and isolation ratings. The 165S18 carries active product status with ROHS3 compliance and REACH unaffected certification, ensuring regulatory alignment for new installations and system replacements.

Physical dimensions differ between the two models. The 167S18 measures 79.50mm L x 95.25mm W x 96.77mm H, while the 165S18 measures 95.25mm L x 88.90mm W x 79.50mm H. Chassis mounting compatibility must be verified based on available space and mounting hole alignment in the target application.

Frequently Asked Questions (FAQ)

Q: Can the 165S18 directly replace the 167S18 in existing applications?

A: The 165S18 provides electrical equivalence to the 167S18 across all functional parameters including voltage ratings, current capacity, winding configuration, and isolation voltage. Physical dimensions differ, requiring verification of mounting space and hole alignment before installation.

Q: What are the key electrical parameters that define substitution compatibility?

A: Substitution compatibility is determined by matching primary voltage (115V), secondary voltage (18V), maximum output current (10A), power rating (180VA), core type (laminated), winding configuration (single primary and secondary with center tap), mounting type (chassis mount), termination style (wire leads), and isolation voltage (2000Vrms).

Q: Are there compliance differences between the 167S18 and 165S18?

A: Both components are ROHS3 compliant and REACH unaffected. No compliance differences exist between the two models.

Q: Why is the 167S18 listed as obsolete?

A: The 167S18 has been superseded by the 165S18 in Hammond Manufacturing's active product line. The 165S18 maintains identical electrical specifications while offering current production availability and support.

Q: What packaging differences exist between these transformers?

A: The 167S18 is available in standard packaging, while the 165S18 is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact electrical or mechanical compatibility.
