DA10 DIP Switch SPST 10 Position Equivalent & Substitute Parts

Part Overview

The DA10 is a slide-actuated DIP switch manufactured by APEM Inc., configured as a single-pole single-throw (SPST) switch with 10 positions. It is rated for 50mA at 24VDC and features through-hole, right-angle mounting with PC pin termination. The DA10 is classified as obsolete, making identification of functionally equivalent substitute parts necessary for ongoing design support and component procurement.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the DA10 must maintain compatibility across the following critical parameters:

• Circuit Configuration: SPST topology required
• Number of Positions: 10-position configuration
• Voltage Rating: 24VDC minimum
• Mounting Interface: Through-hole, right-angle orientation with PC pin termination
• Pitch Spacing: 0.100" (2.54mm) full pitch
• Height Above Board: 0.390" (9.90mm) maximum
• Operating Temperature: -20°C to 70°C range
• Regulatory Compliance: ROHS3 and REACH requirements

The NDA-10-V qualifies as a substitute based on these parameters. However, the current rating differs: the NDA-10-V is rated for 25mA versus the DA10's 50mA. This reduction in current capacity must be evaluated against circuit requirements.

Parameter Comparison

Engineering Selection Recommendations

The NDA-10-V (Base Product Number: NDA-10) is the primary substitute for the obsolete DA10. Both components are manufactured by APEM Inc. and share identical mechanical and electrical interfaces, with the exception of current rating.

Selection Criteria:

• Current Capacity: The NDA-10-V is rated for 25mA maximum, compared to the DA10's 50mA. Substitution is appropriate only when circuit current draw does not exceed 25mA per switch position.
• Product Status: The NDA-10-V is active and in current production, ensuring long-term availability and supply chain continuity.
• Regulatory Compliance: Both components meet ROHS3 and REACH requirements, with identical MSL 1 moisture sensitivity classification.
• Mechanical Compatibility: Identical mounting footprint, pitch spacing, and height above board ensure direct PCB layout compatibility without redesign.

Frequently Asked Questions (FAQ)

Q: Can the NDA-10-V directly replace the DA10 in existing designs?

A: Mechanical and electrical interface compatibility is confirmed. However, the NDA-10-V's 25mA current rating must be verified against your circuit's actual current draw per switch position. If circuit current exceeds 25mA, the NDA-10-V is not suitable.

Q: Are there any PCB layout changes required when substituting the NDA-10-V for the DA10?

A: No. Both components share identical pitch (0.100"), height above board (0.390"), and through-hole right-angle PC pin termination. PCB layouts are directly compatible without modification.

Q: What is the difference in contact material between the DA10 and NDA-10-V?

A: The DA10 specifies phosphor bronze contact material with gold finish. The NDA-10-V contact material is not specified in available documentation, though both maintain gold contact finish. Both are rated for identical electrical life (2,000 cycles) at 24VDC.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both the DA10 and NDA-10-V are ROHS3 compliant and REACH unaffected, with identical MSL 1 (unlimited) moisture sensitivity classification.

Q: What is the mechanical life difference between these components?

A: The DA10 specifies 5,000 mechanical cycles. The NDA-10-V mechanical life is not specified in available documentation. Both are rated for 2,000 electrical cycles at 24VDC.
