Equivalent & Substitute Parts Reference: Hammond Manufacturing 834

Part Overview

The Hammond Manufacturing 834 is a chassis mount 1:4 audio transformer with primary impedance options of 20k or 5k/5k ohms and secondary impedance options of 40k or 10k/10k ohms, designed for broadcast quality applications with a frequency range of 50Hz to 15kHz and a frequency response of ±0.5dB. The part is currently listed as obsolete, making identification of alternatives necessary for design continuity and ongoing production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitutes are grouped strictly by matching essential electrical and mechanical parameters as provided: turns ratio (1:4), impedance values, frequency range (50Hz to 15kHz), frequency response (±0.5dB), power level, and RoHS3 compliance, combined with mounting style compatibility. Only documented manufacturer part numbers with explicitly stated matches across these parameters are considered suitable substitutes.

Key parameters determining substitutions:

• Turns Ratio - Primary:Secondary
• Impedance - Primary (Ohms)
• Impedance - Secondary (Ohms)
• Frequency Range
• Frequency Response
• Power Level
• Mounting Type
• RoHS Compliance

Parameter Comparison

Engineering Selection Recommendations

Selection of alternative parts for the Hammond Manufacturing 834 should be based on the component's status as obsolete and the requirement for compatible, active parts with documented RoHS3 compliance. Only parts with explicitly matched electrical and mechanical parameters, as detailed above, are suitable for substitution.

Frequently Asked Questions (FAQ)

Q1: What defines a valid substitute for the Hammond Manufacturing 834 audio transformer?
A valid substitute must match the electrical parameters (turns ratio, impedance, frequency range, power level), mounting type, and compliance requirements as documented.

Q2: Are differences in termination style acceptable for substitution?
Termination style is listed for both parts; selection must be based on compatibility with mating connectors or soldering practices. Solder lug (834) and wire leads (834A) are distinct options provided.

Q3: Is RoHS compliance required for substitute selection?
Yes, RoHS3 compliance is directly specified and must match to ensure regulatory conformity.

Q4: How should inventory availability factor into substitution?
Both the main part and substitute part list inventory quantities, allowing engineers to prioritize parts with higher availability for immediate production needs.

Q5: Can any part outside the explicitly listed substitutes be considered compatible?
Only documented part numbers matching the provided parameters can be considered as substitutes based on strict engineering criteria. No assumptions should be made about compatibility.
