DPL10T Equivalent & Substitute Parts

Part Overview

The DPL10T is a 10-position DIP switch manufactured by APEM Inc., designed for through-hole, right-angle mounting applications. This SPST (Single Pole Single Throw) switch operates at 24VDC with a 50mA current rating and features a piano actuator with raised actuation level. The product is currently obsolete, making identification of suitable substitute components essential for ongoing system support, maintenance, and new design implementations where equivalent functionality is required.

Key Parameters

Substitute Part Grouping Explanation

Substitute identification for the DPL10T is based on strict electrical and mechanical parameter alignment. The primary substitution candidate must satisfy the following mandatory criteria:

Electrical Parameters:

• Circuit configuration: SPST
• Voltage rating: 24VDC
• Number of positions: 10

Mechanical Parameters:

• Actuator type: Piano with raised level
• Mounting configuration: Through hole, right angle
• Pitch spacing: 0.100" (2.54mm)
• Height above board: 0.402" (10.20mm)
• Termination style: PC pin

Current Rating Consideration: The DPL10T operates at 50mA. Substitute parts with lower current ratings (such as 25mA) may be considered for applications where the actual circuit current demand does not exceed the substitute's rating. This determination must be made based on specific application requirements.

Compliance and Status: All substitute parts must maintain ROHS3 compliance and be available in active product status to ensure long-term supply chain viability.

Parameter Comparison

Engineering Selection Recommendations

The NDPL-10T-V from APEM Inc. serves as the active-status equivalent for the obsolete DPL10T. Both components share identical mechanical form factors, electrical circuit configuration, and environmental operating parameters. The NDPL-10T-V maintains ROHS3 compliance and is currently in active production, ensuring supply chain continuity.

The primary technical distinction is the current rating: the NDPL-10T-V is rated at 25mA versus the DPL10T's 50mA specification. Selection of the NDPL-10T-V is appropriate for applications where the actual circuit current does not exceed 25mA. For applications requiring the full 50mA capability of the original DPL10T, alternative substitute parts with matching current ratings must be evaluated.

Both components feature identical pitch spacing (0.100"), height above board (0.402"), and gold-plated contacts, ensuring direct mechanical and electrical compatibility in PCB layouts designed for the DPL10T footprint.

Frequently Asked Questions (FAQ)

Q: Can the NDPL-10T-V directly replace the DPL10T in existing designs?

A: Direct replacement is possible from a mechanical and mounting perspective. The NDPL-10T-V maintains identical pitch, height, and through-hole right-angle configuration. However, the current rating difference (25mA versus 50mA) must be evaluated against actual circuit requirements. If the application current draw does not exceed 25mA, the NDPL-10T-V is a suitable substitute.

Q: What is the significance of the current rating difference?

A: The DPL10T is rated for 50mA continuous current, while the NDPL-10T-V is rated for 25mA. The substitute part will safely operate only within its specified current rating. Exceeding this rating may result in contact degradation or switch failure. Application circuit analysis is required to confirm that actual current demand does not exceed 25mA.

Q: Are the mechanical dimensions identical between these parts?

A: Yes. Both the DPL10T and NDPL-10T-V share identical pitch spacing (0.100" / 2.54mm), height above board (0.402" / 10.20mm), and through-hole right-angle mounting configuration. PCB layouts designed for the DPL10T will accommodate the NDPL-10T-V without modification.

Q: What compliance certifications apply to the NDPL-10T-V?

A: The NDPL-10T-V is ROHS3 compliant and REACH unaffected, matching the compliance profile of the original DPL10T. Both components meet current environmental and regulatory requirements for electronic component manufacturing.

Q: Why is the DPL10T listed as obsolete?

A: The DPL10T has been discontinued by APEM Inc. The NDPL-10T-V represents the active-production equivalent within the APEM DIP switch product line, offering the same functional and mechanical characteristics with current manufacturing support.

Q: Are there any differences in contact material or finish?

A: Both components feature gold-plated contacts. Contact material specifications are not provided for the NDPL-10T-V; however, the gold finish ensures consistent electrical performance and corrosion resistance across both parts.
