Equivalent & Substitute Parts for Hammond Manufacturing 813

Part Overview

The Hammond Manufacturing 813 is an audio transformer designed with chassis mount capability, supporting impedance ranges of 600, 150/150 ohms on the primary and 2.4k, 600/600 ohms on the secondary. This transformer operates in the 50Hz ~ 15kHz frequency range and features a ±0.5dB frequency response, making it suitable for broadcast-quality audio applications. The 813 is currently listed as obsolete, and in-stock quantities are limited. Identifying substitute models is necessary to maintain long-term design support and ensure ongoing supply availability for replacements or new design-in requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts are identified exclusively by matching the provided key electrical and mechanical parameters within the same product category. The following criteria are referenced: manufacturer part number, series, impedance (primary and secondary), frequency range, frequency response, power level, mounting type, termination style, compliance (RoHS, REACH), inventory levels, and part status. Only parts with directly stated, matching, or compatible values for these fields are included as substitutes.

Parameter Comparison

Engineering Selection Recommendations

Selection of Hammond Manufacturing 813A as a substitute for 813 can be based on the following: both models are ROHS3 compliant and REACH unaffected, supporting regulatory compliance requirements. The 813A maintains an active part status and is available in new original stock. Inventory of 813A is sufficient for production and maintenance needs. All substitute selection must reference only documented parameters and compliance statements.

Frequently Asked Questions (FAQ)

Q1: How is substitute compatibility determined between Hammond Manufacturing 813 and 813A?
A1: Compatibility is determined strictly by reference to manufacturer, series, frequency range, frequency response, power level, mounting type, termination style, inventory level, part status, and compliance fields as listed in the product documentation.

Q2: Are package and mounting styles considered in substitution?
A2: Yes. Both models use chassis mount, though the termination style differs (solder lug for 813, wire leads for 813A). Only parameters explicitly listed are referenced in substitution.

Q3: Do RoHS and REACH status affect component substitution?
A3: Yes. Both 813 and 813A are ROHS3 compliant and REACH unaffected, ensuring that compliance criteria are met for regulated environments.

Q4: Why is the 813A chosen as equivalent to the 813?
A4: The 813A shares all key operating and compliance parameters as listed in the documentation, except for termination style and series identifier. Both support chassis mounting and same operational frequency ranges, with sufficient inventory and active part status.

Q5: Is part status relevant in substitute selection?
A5: Yes. The 813 is obsolete while the 813A is active, supporting ongoing production and maintenance requirements. Only documented inventory levels and part status are reported.
