167S5 Equivalent & Substitute Parts Reference

Part Overview

The 167S5 is a laminated core power transformer manufactured by Hammond Manufacturing, rated for 50VA with a 115V primary and 5V secondary output. This chassis-mount transformer features a center tap and wire lead termination, designed for applications requiring isolated low-voltage power conversion. The 167S5 is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

The 166S5 qualifies as a functional substitute for the 167S5 based on the following critical parameters:

• Electrical Specifications: Both transformers maintain identical primary voltage (115V), secondary voltage (5V), maximum output current (10A), and power rating (50VA)
• Core Configuration: Both utilize laminated core construction with center tap configuration
• Isolation Rating: Both provide 2000Vrms isolation voltage
• Mounting and Termination: Both feature chassis mount design with wire lead termination
• Compliance: Both are ROHS3 compliant with REACH unaffected status

The primary differences between these parts are dimensional (physical size and height) and product status (167S5 is obsolete; 166S5 is active). These differences do not affect electrical interchangeability when space constraints are not limiting factors.

Parameter Comparison

Engineering Selection Recommendations

The 166S5 is the direct substitute for the obsolete 167S5. Both transformers are manufactured by Hammond Manufacturing and share identical electrical and functional specifications. The 166S5 is currently in active production status with confirmed inventory availability, making it the appropriate choice for replacement applications.

Selection between these parts should be based on physical space constraints within the target application. The 167S5 measures 55.63mm L × 66.80mm W × 66.80mm H, while the 166S5 measures 93.73mm L × 54.10mm W × 58.67mm H. Verify that the 166S5 dimensions accommodate the available mounting space in your chassis or enclosure before final component selection.

Both parts maintain ROHS3 compliance and REACH unaffected status, satisfying current environmental and regulatory requirements for electronic component procurement.

Frequently Asked Questions (FAQ)

Q: Can the 166S5 directly replace the 167S5 in existing designs?

A: Yes, the 166S5 provides electrical equivalence to the 167S5. Both transformers deliver identical voltage transformation (115V to 5V), power capacity (50VA), output current (10A), and isolation characteristics (2000Vrms). Substitution is valid provided the physical dimensions of the 166S5 fit within the available mounting space.

Q: What are the key differences between the 167S5 and 166S5?

A: The primary differences are physical dimensions and product status. The 167S5 is obsolete, while the 166S5 is active production. The 166S5 is longer (93.73mm vs. 55.63mm) but slightly shorter in height (58.67mm vs. 66.80mm) and narrower in width (54.10mm vs. 66.80mm).

Q: Are there any compliance or certification differences?

A: No. Both the 167S5 and 166S5 are ROHS3 compliant and REACH unaffected. They maintain identical isolation voltage ratings and regulatory status.

Q: What should I verify before implementing the 166S5 as a substitute?

A: Confirm that the 166S5 physical dimensions fit within your chassis or enclosure mounting location. Verify that wire lead routing and connection points are compatible with your circuit board layout. Both transformers use identical wire lead termination, so electrical connections remain unchanged.

Q: Is the 166S5 currently available?

A: Yes. The 166S5 is in active production status with confirmed inventory of 857 pieces available as new original stock.
