Key Parameters

Substitute Part Grouping Explanation

Substitution is determined strictly by matching the following key parameters: turns ratio (1:1), primary and secondary impedance (as listed), frequency range (50Hz ~ 15kHz), frequency response (±0.5dB), mounting type (chassis mount), power level (15dB), RoHS compliance, and REACH status. Substitute parts must match these explicit parameters to ensure electrical and mechanical compatibility.

Parameter Comparison

Engineering Selection Recommendations

The Hammond Manufacturing 835 is obsolete, and the current substitute, Hammond Manufacturing 835A, is active. Both parts are ROHS3 Compliant and REACH Unaffected. Selection can proceed based on provided compliance and regulatory status. No additional technical criteria are introduced.

Frequently Asked Questions (FAQ)

Q: What parameters are used to determine suitable substitute parts for the Hammond Manufacturing 835 audio transformer?
A: Key parameters include turns ratio, impedance, frequency range, frequency response, mounting type, power level, RoHS status, and REACH status.

Q: Is the Hammond Manufacturing 835A a direct substitute for the 835?
A: The Hammond Manufacturing 835A matches major electrical and mechanical parameters, compliance, and regulatory standards as provided.

Q: Are there differences in termination style between the 835 and 835A?
A: The 835 uses solder lug termination, while the 835A uses wire leads. This can impact compatibility with pre-existing PCB layouts or wiring harnesses.

Q: How does the product status impact part selection?
A: The 835 is marked obsolete, so available stock is limited. The 835A is active, making it suitable for ongoing procurement under the provided parameters.

Q: Are both the 835 and 835A compliant with RoHS and REACH regulations?
A: Both are listed as ROHS3 Compliant and REACH Unaffected in the provided data.
