DA07TN DIP Switch SPST 7-Position Equivalent & Substitute Parts

Part Overview

The DA07TN is a slide-actuated DIP switch manufactured by APEM Inc., configured as a single-pole single-throw (SPST) switch with 7 positions. This component is rated for 50mA at 24VDC and features through-hole, right-angle mounting with gold-plated phosphor bronze contacts. The DA07TN is classified as obsolete, making identification of suitable substitute components necessary for ongoing system support and new design implementations.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the DA07TN is determined by the following critical parameters:

• Circuit Configuration: Must be SPST
• Number of Positions: Must be 7
• Voltage Rating: Must be 24VDC
• Actuator Type: Must be Slide (Standard)
• Mounting Type: Must be Through Hole, Right Angle
• Pitch: Must be 0.100" (2.54mm)
• Height Above Board: Must be 0.390" (9.90mm)

The NDA-07T-V meets all critical substitution criteria. The primary difference is the current rating: the NDA-07T-V is rated for 25mA versus the DA07TN's 50mA. This represents a reduction in maximum current capacity and must be evaluated against actual circuit requirements. The NDA-07T-V is an active product from APEM Inc., ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The NDA-07T-V is the qualified substitute for the DA07TN based on the following factors:

Compliance and Certification: Both components are ROHS3 compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, ensuring compatibility with standard manufacturing and storage protocols.

Product Status: The DA07TN is obsolete, while the NDA-07T-V is active. Selection of the NDA-07T-V ensures access to current inventory, technical support, and long-term availability.

Electrical Compatibility: Both components operate at 24VDC with identical circuit configuration (SPST), position count (7), and electrical life (2,000 cycles). The NDA-07T-V's 25mA current rating is lower than the DA07TN's 50mA rating. Component selection must confirm that circuit current requirements do not exceed 25mA.

Mechanical Compatibility: Identical mounting footprint, pitch, height above board, and actuator characteristics ensure direct mechanical substitution without PCB redesign.

Frequently Asked Questions (FAQ)

Q: Can the NDA-07T-V directly replace the DA07TN in existing designs?

A: Direct replacement is possible if circuit current requirements do not exceed 25mA. The NDA-07T-V has identical mechanical and electrical characteristics except for current rating. If the original design draws more than 25mA, the NDA-07T-V is not suitable.

Q: What is the primary difference between these two components?

A: The current rating differs: DA07TN is rated for 50mA, while NDA-07T-V is rated for 25mA. All other parameters, including voltage, position count, mounting type, and pitch, are identical.

Q: Are there any packaging or footprint differences?

A: No. Both components share identical pitch (0.100"), height above board (0.390"), and through-hole right-angle mounting configuration. No PCB layout modifications are required.

Q: Why is the DA07TN obsolete?

A: The DA07TN is classified as obsolete by APEM Inc. The NDA-07T-V represents the current active product line for this switch category.

Q: Do both components meet RoHS requirements?

A: Yes. Both the DA07TN and NDA-07T-V are ROHS3 compliant and carry identical moisture sensitivity levels (MSL 1, Unlimited).
