D3065 Telecom Relay DPDT 2A 9V Equivalent & Substitute Parts

Part Overview

The D3065 is a telecom-grade double-pole double-throw (DPDT) relay manufactured by TE Connectivity Potter & Brumfield Relays, part of the FP2 and AXICOM series. This through-hole mounted relay operates at 9VDC with a 2A contact rating and is designed for telecom switching applications. The D3065 is classified as obsolete, making equivalent substitute parts necessary for ongoing system maintenance and new design implementations where this relay specification is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the D3065 telecom relay are identified based on strict electrical and mechanical compatibility criteria. The following parameters must align for substitution eligibility:

Critical Matching Parameters:

• Coil Voltage: 9VDC
• Contact Form: DPDT (2 Form C)
• Coil Type: Latching, Dual Coil
• Coil Current: 22.2 mA
• Coil Resistance: 405 Ohms
• Mounting Type: Through Hole
• Termination Style: PC Pin
• Relay Type: Telecom

Allowable Variation Parameters:

• Contact Rating (Current): The D3065 specifies 2A; substitute parts may operate at lower current ratings (1A) provided the application does not exceed the substitute's rating
• Switching Voltage: The D3065 supports 250VAC and 220VDC maximum; substitutes with lower switching voltage ratings (125VAC, 110VDC) are acceptable for applications within those limits
• Operating Temperature Range: The D3065 operates -40°C to 85°C; substitutes with narrower ranges (-40°C to 70°C) are acceptable for applications within those limits
• Operate/Release Time: The D3065 specifies 20ms; substitutes with faster response times (3ms) are acceptable
• Contact Material: Composition differences are acceptable provided the substitute maintains telecom-grade reliability

The substitute parts TQ2-L2-9V and TQ2H-L2-9V, both manufactured by Panasonic Electric Works from the TQ series, meet all critical matching parameters and are classified as active products with current availability.

Parameter Comparison

Engineering Selection Recommendations

D3065 Obsolescence Context: The D3065 is classified as obsolete, necessitating substitution for new procurements and system replacements. Both substitute parts (TQ2-L2-9V and TQ2H-L2-9V) are active products with confirmed current inventory availability.

Compliance and Regulatory Status: Both substitute parts maintain REACH Unaffected status, matching the regulatory profile of the original D3065. The TQ2-L2-9V and TQ2H-L2-9V are RoHS compliant, providing enhanced environmental compliance compared to the D3065 specification.

Current Rating Consideration: The D3065 supports 2A contact rating, while both substitute parts are rated at 1A. Selection of substitute parts is appropriate for applications where the maximum continuous or switching current does not exceed 1A. Applications requiring the full 2A capability of the D3065 cannot be directly substituted with these parts.

Switching Voltage Consideration: The D3065 supports switching voltages up to 250VAC and 220VDC. The substitute parts support maximum switching voltages of 125VAC and 110VDC. Substitution is appropriate for applications operating within these lower voltage limits. Applications requiring the higher switching voltage capability of the D3065 cannot be directly substituted.

Operating Temperature Consideration: The D3065 operates across -40°C to 85°C. The substitute parts operate across -40°C to 70°C. Substitution is appropriate for applications where the maximum operating temperature does not exceed 70°C. Applications requiring operation above 70°C cannot use these substitute parts.

Response Time Consideration: The substitute parts exhibit faster operate and release times (3ms versus 20ms). This represents an improvement in switching speed and does not create compatibility issues for applications designed for the D3065's 20ms response time.

Packaging Differentiation: TQ2-L2-9V is supplied in tube packaging, while TQ2H-L2-9V is supplied in box packaging. Selection between these two substitutes depends on procurement and handling requirements; both are electrically and mechanically identical.

Frequently Asked Questions (FAQ)

Q: Can the TQ2-L2-9V or TQ2H-L2-9V directly replace the D3065 in all applications?

A: Direct substitution is possible only when the application meets all of the following conditions: (1) maximum continuous or switching current does not exceed 1A, (2) switching voltage does not exceed 125VAC or 110VDC, and (3) maximum operating temperature does not exceed 70°C. Applications exceeding any of these parameters require engineering evaluation.

Q: What is the difference between TQ2-L2-9V and TQ2H-L2-9V?

A: The TQ2-L2-9V and TQ2H-L2-9V are electrically and mechanically identical. The primary difference is packaging: TQ2-L2-9V is supplied in tube packaging, while TQ2H-L2-9V is supplied in box packaging. Selection depends on procurement, storage, and handling requirements.

Q: Why do the substitute parts have a lower current rating (1A) than the D3065 (2A)?

A: The TQ2-L2-9V and TQ2H-L2-9V are designed for telecom applications with lower current requirements. The 1A rating is sufficient for standard telecom switching circuits. Applications requiring 2A switching capability must identify alternative substitutes or continue using the D3065 if available from inventory.

Q: Are the substitute parts RoHS compliant?

A: Yes. Both TQ2-L2-9V and TQ2H-L2-9V are RoHS compliant, providing enhanced environmental compliance. The D3065 RoHS status is not specified in the available documentation.

Q: What is the impact of the faster response time (3ms) in the substitute parts compared to the D3065 (20ms)?

A: The faster response time of the substitute parts represents an improvement. Applications designed for the D3065's 20ms response time will function correctly with the faster 3ms response time of the substitute parts. No circuit modifications are required.

Q: Can the substitute parts operate at temperatures above 70°C?

A: No. The TQ2-L2-9V and TQ2H-L2-9V are rated for operation from -40°C to 70°C. Applications requiring operation above 70°C cannot use these substitute parts. The D3065 supports operation up to 85°C.

Q: What is the coil resistance of the substitute parts?

A: Both TQ2-L2-9V and TQ2H-L2-9V have a coil resistance of 405 Ohms, matching the D3065. This ensures compatibility with existing drive circuits designed for the D3065.

Q: Are there inventory considerations when selecting between the substitute parts?

A: Both substitute parts have confirmed current inventory availability. TQ2-L2-9V has 1,781 pieces in stock, while TQ2H-L2-9V has 1,108 pieces in stock. Procurement timelines and quantity requirements may influence selection between these two options.
