TE Connectivity Potter & Brumfield D3064 Telecom Relay DPDT Equivalent & Substitute Parts

Part Overview

The TE Connectivity Potter & Brumfield D3064 is a telecom relay with DPDT (2 Form C) contact configuration, rated for 2A at 6VDC coil voltage. This component is classified as obsolete, necessitating identification of active substitute parts for ongoing applications. The D3064 features latching dual-coil operation with through-hole PC pin termination, suitable for telecom switching applications requiring 250VAC/220VDC maximum switching voltage.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the D3064 is determined by the following critical parameters that must align between the main part and substitute candidates:

Primary Matching Criteria:

• Coil voltage: 6VDC (exact match required)
• Contact form: DPDT (2 Form C) (exact match required)
• Coil type: Latching, dual coil (exact match required)
• Mounting type: Through hole (exact match required)
• Termination style: PC pin (exact match required)
• Coil resistance: 180 Ohms (exact match required)
• Coil current: 33.3 mA (exact match required)

Secondary Compatibility Considerations:

• Contact rating current: Substitute must meet or exceed application requirements
• Switching voltage: Substitute must meet or exceed application requirements
• Operating temperature range: Substitute must encompass application operating conditions
• Relay type: Telecom classification maintained

The Panasonic Electric Works TQ2-L2-6V satisfies all primary matching criteria and maintains telecom relay classification. Differences in contact rating current (1A vs. 2A) and switching voltage (125VAC/110VDC vs. 250VAC/220VDC) represent derating factors that require application-level evaluation.

Parameter Comparison

Engineering Selection Recommendations

The Panasonic Electric Works TQ2-L2-6V is an active substitute for the obsolete TE Connectivity Potter & Brumfield D3064. Both components share identical coil voltage, contact form, coil type, mounting configuration, and termination style, establishing functional equivalence for latching dual-coil telecom relay applications.

Compliance Status:

• D3064: REACH Unaffected, EAR99 classification
• TQ2-L2-6V: REACH Unaffected, RoHS3 Compliant, EAR99 classification

The TQ2-L2-6V provides enhanced regulatory compliance through RoHS3 certification, supporting modern supply chain requirements. Both components maintain identical HTSUS classification (8536.41.0020) and MSL rating (1 - Unlimited).

Performance Derating Factors: The TQ2-L2-6V operates with reduced contact current rating (1A vs. 2A) and reduced maximum switching voltage (125VAC/110VDC vs. 250VAC/220VDC). Applications requiring the full 2A contact rating or 250VAC/220VDC switching capability must evaluate whether the TQ2-L2-6V meets load specifications. The TQ2-L2-6V demonstrates faster switching response (3ms vs. 20ms operate and release times) and operates within a narrower temperature range (-40°C to 70°C vs. -40°C to 85°C).

Frequently Asked Questions (FAQ)

Q: Can the Panasonic TQ2-L2-6V directly replace the TE Connectivity D3064 in all applications?

A: The TQ2-L2-6V is functionally equivalent for coil control and contact switching topology. However, applications must verify that the reduced contact current rating (1A vs. 2A) and reduced switching voltage (125VAC/110VDC vs. 250VAC/220VDC) satisfy load requirements. The narrower operating temperature range (-40°C to 70°C) must also accommodate application conditions.

Q: What are the key electrical parameters that must match for substitution?

A: Coil voltage (6VDC), contact form (DPDT), coil type (latching dual coil), coil resistance (180 Ohms), and coil current (33.3 mA) must be identical. These parameters ensure compatible control circuitry and mechanical operation.

Q: How do the switching characteristics differ between these relays?

A: The TQ2-L2-6V operates significantly faster (3ms vs. 20ms for both operate and release times). The D3064 requires 4.2VDC minimum to operate, while the TQ2-L2-6V requires 4.5VDC. Applications sensitive to switching speed or minimum voltage thresholds must account for these differences.

Q: What is the significance of the contact material differences?

A: The D3064 uses Palladium, Ruthenium, and Gold contact materials, while the TQ2-L2-6V uses Silver and Gold. Contact material composition affects switching characteristics, contact resistance, and suitability for specific load types. Applications involving inductive loads, capacitive loads, or low-level signal switching may respond differently to these material compositions.

Q: Are there packaging considerations for PCB assembly?

A: Both relays feature through-hole PC pin termination suitable for traditional PCB mounting. The TQ2-L2-6V is supplied in tube packaging, while the D3064 packaging specification is not provided. Verify tube packaging compatibility with assembly equipment and handling procedures.

Q: What regulatory compliance advantages does the TQ2-L2-6V provide?

A: The TQ2-L2-6V carries RoHS3 compliance certification, supporting modern environmental and supply chain requirements. Both components maintain REACH Unaffected status and EAR99 export classification. The TQ2-L2-6V is an active product, ensuring ongoing availability and supply chain support.

Q: How should contact rating derating be evaluated?

A: The TQ2-L2-6V contact rating of 1A represents a 50% reduction from the D3064 rating of 2A. Applications must calculate actual load current and verify that 1A contact rating provides adequate margin. Switching voltage derating (125VAC/110VDC vs. 250VAC/220VDC) similarly requires verification that application voltages remain within TQ2-L2-6V specifications.
