DPL04T Equivalent & Substitute Parts

Part Overview

The DPL04T is a 4-position DIP switch manufactured by APEM Inc., designed for through-hole, right-angle mounting applications. This SPST (Single Pole Single Throw) switch features a piano actuator and is rated for 50mA at 24VDC. The product is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support, maintenance, and new design implementations where legacy component compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DPL04T must satisfy the following critical parameters to ensure functional equivalence:

• Circuit Configuration: SPST topology is mandatory for direct substitution
• Number of Positions: 4-position requirement must be maintained
• Current Rating: Minimum 50mA at rated voltage
• Voltage Rating: 24VDC nominal operation
• Actuator Type: Piano actuator for consistent user interface
• Mounting Type: Through-hole, right-angle orientation for PCB compatibility
• Pitch: 0.100" (2.54mm) standard spacing for footprint alignment
• Height Above Board: Physical clearance constraint of 0.402" (10.20mm) or less
• Contact Material & Finish: Phosphor bronze with gold plating for reliability
• Operating Temperature: -20°C to 70°C range
• Compliance: ROHS3 compliance required for regulatory alignment

No substitute parts have been provided in the input data. Equivalent alternatives must be sourced from component distributors and verified against all parameters listed above.

Parameter Comparison

No substitute parts are available for comparison at this time. When evaluating potential alternatives, use the Key Parameters table above as the baseline specification for all electrical, mechanical, and environmental criteria.

Engineering Selection Recommendations

When sourcing replacements for the obsolete DPL04T:

• Verify ROHS3 compliance status to maintain regulatory alignment with current manufacturing standards
• Confirm MSL (Moisture Sensitivity Level) rating compatibility with existing assembly processes
• Validate mechanical life rating of 5,000 cycles minimum to ensure equivalent operational durability
• Confirm electrical life rating of 2,000 cycles minimum for switching reliability
• Ensure contact material (phosphor bronze with gold finish) specification to maintain electrical performance and corrosion resistance
• Verify through-hole, right-angle mounting compatibility with existing PCB layouts
• Confirm 0.100" (2.54mm) pitch spacing for footprint compatibility

Frequently Asked Questions (FAQ)

Q: Why is the DPL04T classified as obsolete? A: The DPL04T is no longer in active production by APEM Inc. Obsolete status indicates the manufacturer has discontinued this model, requiring users to identify functionally equivalent alternatives for ongoing support and new designs.

Q: What defines a valid substitute for the DPL04T? A: A valid substitute must maintain identical SPST circuit configuration, 4-position count, 50mA minimum current rating at 24VDC, piano actuator type, through-hole right-angle mounting, 0.100" pitch, and equivalent mechanical/electrical life ratings. All parameters listed in the Key Parameters table must be matched or exceeded.

Q: Can I use a different actuator type as a substitute? A: No. The piano actuator is a functional requirement for this application. Substitutes must use identical actuator type to ensure consistent user interface and operational characteristics.

Q: Is height above board a critical parameter for substitution? A: Yes. The 0.402" (10.20mm) height specification is a mechanical constraint. Substitute parts must not exceed this dimension to ensure PCB clearance compatibility and prevent interference with adjacent components.

Q: Does the contact material specification affect substitution eligibility? A: Yes. Phosphor bronze with gold plating is specified for electrical performance and corrosion resistance. Substitute parts must use equivalent contact materials to maintain reliability and signal integrity.

Q: What is the significance of ROHS3 compliance? A: ROHS3 compliance ensures the component meets current environmental and regulatory standards for hazardous substance restrictions. This status is required for modern manufacturing and supply chain compatibility.
