DG307ACJ Equivalent & Substitute Parts

Part Overview

The DG307ACJ is a dual-circuit SPDT (Single Pole Double Throw) analog switch IC manufactured by Analog Devices Inc./Maxim Integrated. This 14-DIP through-hole component provides 2:1 multiplexing functionality with 50Ohm on-state resistance, designed for signal routing and switching applications in analog systems.

The DG307ACJ is classified as obsolete. Identifying equivalent and substitute parts is necessary to maintain design continuity, ensure supply chain availability, and support legacy system maintenance and production requirements.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DG307ACJ is determined by the following critical parameters:

• Switch Circuit Type: SPDT (required match)
• Multiplexer Configuration: 2:1 (required match)
• On-State Resistance: 50Ohm (required match)
• Dual Supply Voltage Range: ±5V ~ 18V (required match)
• Switch Timing: Ton ≤ 250ns, Toff ≤ 150ns (required match)
• Charge Injection: 12pC (required match)
• Channel Capacitance: 14pF (required match)
• Leakage Current: ≤ 5nA (required match)
• Crosstalk: -74dB @ 500kHz (required match)
• Operating Temperature: 0°C ~ 70°C (required match)
• Package / Case: 14-DIP (required match)
• Mounting Type: Through Hole (required match)

Two substitute parts meet these criteria:

1. DG307ACJ+ (Direct Equivalent): Identical electrical and mechanical specifications with active product status and improved RoHS compliance.

2. DG305ACJ+ (Parametric Equivalent): Matches all electrical parameters and package specifications. The primary difference is the number of circuits: DG305ACJ+ contains 1 circuit versus 2 circuits in the DG307ACJ. This part is suitable for applications requiring single-circuit functionality within the same electrical performance envelope.

Parameter Comparison

Engineering Selection Recommendations

DG307ACJ+ (Direct Equivalent) is the primary substitute for the obsolete DG307ACJ. This part provides identical electrical performance and mechanical compatibility while offering active product status and ROHS3 compliance. The DG307ACJ+ is suitable for direct replacement in all applications currently using the DG307ACJ.

DG305ACJ+ (Parametric Equivalent) is applicable only in designs requiring single-circuit switching functionality. While all electrical parameters and package specifications match the DG307ACJ, the reduced circuit count (1 versus 2) limits its use to applications that do not require dual-circuit operation. The DG305ACJ+ offers active product status and ROHS3 compliance.

Both substitute parts maintain compatibility with the original ±5V ~ 18V dual supply voltage range, switching timing specifications, and 14-DIP through-hole package format. Selection between DG307ACJ+ and DG305ACJ+ depends on circuit requirements for single or dual switching functionality.

Frequently Asked Questions (FAQ)

Q: Can DG307ACJ+ be used as a direct replacement for DG307ACJ?

A: Yes. The DG307ACJ+ provides identical electrical specifications, switching characteristics, and 14-DIP package format. The primary advantages are active product status and ROHS3 compliance.

Q: What is the key difference between DG307ACJ+ and DG305ACJ+?

A: The DG307ACJ+ contains 2 independent SPDT circuits, while the DG305ACJ+ contains 1 SPDT circuit. All other electrical parameters, including on-state resistance, switching time, charge injection, and operating voltage range, are identical. Selection depends on whether your application requires single or dual switching circuits.

Q: Are the substitute parts pin-compatible with the DG307ACJ?

A: Both DG307ACJ+ and DG305ACJ+ use the 14-DIP (0.300", 7.62mm) through-hole package. Pin compatibility depends on circuit configuration. DG307ACJ+ is a direct pin-for-pin replacement. DG305ACJ+ has a different pinout due to single-circuit configuration and requires circuit board layout verification.

Q: What is the significance of RoHS compliance for these parts?

A: The original DG307ACJ is RoHS non-compliant. Both substitute parts (DG307ACJ+ and DG305ACJ+) are ROHS3 compliant, meeting current environmental and regulatory requirements for electronic component manufacturing and assembly.

Q: Are there any supply voltage or operating temperature restrictions when using substitute parts?

A: No. Both substitute parts maintain the original ±5V ~ 18V dual supply voltage range and 0°C ~ 70°C operating temperature specification. Electrical performance remains consistent across the specified operating envelope.

Q: What packaging formats are available for the substitute parts?

A: Both DG307ACJ+ and DG305ACJ+ are supplied in tube packaging. The 14-PDIP supplier device package format remains consistent with the original DG307ACJ.
