DA08 DIP Switch SPST 8-Position Equivalent & Substitute Parts

Part Overview

The DA08 is a DIP switch SPST 8-position through-hole component manufactured by APEM Inc., designed for 24VDC applications with a 50mA current rating. This part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning. The DA08 features a slide actuator with raised level, phosphor bronze contacts finished in gold, and is suitable for applications requiring reliable switching in compact form factors.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DA08 is determined by the following critical parameters:

• Circuit Configuration: Must be SPST (Single Pole Single Throw)
• Number of Positions: Must be 8-position
• Voltage Rating: Must be 24VDC
• Mounting Type: Must be Through Hole, Right Angle
• Pitch: Must be 0.100" (2.54mm)
• Actuator Type: Must be Slide (Standard) with Raised level
• Termination Style: Must be PC Pin

The NDA-08-V qualifies as a substitute part because it matches all critical parameters. However, the current rating differs (25mA versus 50mA), which represents a functional limitation that must be evaluated against application requirements.

Parameter Comparison

Engineering Selection Recommendations

The NDA-08-V is an active product from APEM Inc. that maintains mechanical and electrical compatibility with the obsolete DA08 across all critical form factor and interface parameters. Both parts are ROHS3 compliant and carry identical MSL and REACH designations, ensuring regulatory consistency.

The primary distinction is the current rating: the NDA-08-V is rated for 25mA maximum, compared to the DA08's 50mA rating. This reduction in current capacity must be verified against the application's actual switching current requirements. If the application operates at or below 25mA, the NDA-08-V provides a direct functional replacement. If the application requires current handling above 25mA, the NDA-08-V is not suitable for substitution.

Both parts share identical pitch, mounting orientation, actuator configuration, and operating temperature range, confirming mechanical interchangeability at the PCB level.

Frequently Asked Questions (FAQ)

Q: Can the NDA-08-V be used as a direct replacement for the DA08?

A: The NDA-08-V is mechanically and electrically compatible with the DA08 provided that the application's switching current does not exceed 25mA. If your circuit requires current handling above 25mA, the NDA-08-V cannot be substituted.

Q: What are the key differences between these parts?

A: The primary difference is current rating: DA08 handles 50mA while NDA-08-V handles 25mA. Both parts share identical 8-position SPST configuration, 24VDC rating, 0.100" pitch, through-hole right-angle mounting, and operating temperature range.

Q: Are there any compliance or certification differences?

A: No. Both parts carry identical ROHS3 compliance, REACH Unaffected status, and MSL Level 1 (Unlimited) ratings.

Q: How do I determine if 25mA is sufficient for my application?

A: Review your circuit schematic and calculate the maximum switching current across all 8 positions under worst-case operating conditions. If this value does not exceed 25mA per position, the NDA-08-V is suitable.

Q: Are the physical dimensions identical?

A: The parts share the same height above board (0.390"), pitch (0.100"), and mounting type. Length differs slightly (DA08: 0.859" versus NDA-08-V: 0.850"), but this difference does not affect PCB layout compatibility.

Q: What is the product status difference?

A: The DA08 is obsolete, while the NDA-08-V is active. The NDA-08-V is currently manufactured and available through standard distribution channels.
