Key Parameters

Substitute Part Grouping Explanation

Substitution of the 167S11 is based on electrical and mechanical compatibility across the following critical parameters:

• Voltage specifications: Primary 115V and secondary 11V with center tap configuration
• Power rating: 110VA maximum
• Output current capacity: 10A maximum
• Winding configuration: Single primary and single secondary
• Isolation voltage: 2000Vrms
• Mounting and termination: Chassis mount with wire leads
• Regulatory compliance: ROHS3 and REACH status

The 166S11 meets all electrical specifications and regulatory requirements. Dimensional differences exist between the two models; however, both are chassis-mount configurations with wire lead termination suitable for equivalent circuit applications.

Parameter Comparison

Engineering Selection Recommendations

The 166S11 is the direct substitute for the obsolete 167S11. Both transformers are manufactured by Hammond Manufacturing and share identical electrical specifications, winding configurations, and regulatory compliance certifications.

The 166S11 is currently in active production status with confirmed inventory availability, making it the appropriate selection for applications previously specified with the 167S11. Both parts maintain ROHS3 compliance and REACH unaffected status, ensuring compatibility with current environmental and regulatory requirements.

Dimensional variations exist between the two models. The 167S11 measures 64.60mm L x 82.55mm W x 77.72mm H, while the 166S11 measures 114.30mm L x 64.60mm W x 76.20mm H. Physical space constraints within the target application must be evaluated to confirm mounting compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 166S11 directly replace the 167S11 in existing designs?

A: The 166S11 provides electrical equivalence to the 167S11 across all specified parameters: voltage ratings, power capacity, winding configuration, isolation voltage, and regulatory compliance. Physical dimensions differ; mounting space availability must be confirmed for the specific application.

Q: What is the primary reason for substitution?

A: The 167S11 is classified as obsolete. The 166S11 is an active production part from the same manufacturer with identical electrical specifications, ensuring continued availability for new production and maintenance applications.

Q: Are there compliance differences between the two parts?

A: No. Both the 167S11 and 166S11 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory standards.

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

A: Substitution is based on matching primary voltage (115V), secondary voltage (11V), power rating (110VA), maximum output current (10A), center tap configuration, isolation voltage (2000Vrms), and winding topology (single primary, single secondary).

Q: Do packaging differences affect substitution?

A: The 167S11 is listed with dash packaging, while the 166S11 is supplied in bulk packaging. Both use wire lead termination and chassis mount configuration. Packaging designation does not affect electrical or mechanical compatibility.
