BD08AV2 DIP Switch SPST 8 Position Equivalent & Substitute Parts

Part Overview

The BD08AV2 is an 8-position DIP switch manufactured by C&K, featuring SPST (Single Pole Single Throw) circuit configuration with 100mA at 5VDC rating. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The BD08AV2 is designed for through-hole, right-angle mounting applications with standard slide actuator operation across industrial temperature ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the BD08AV2 is determined by the following critical parameters: circuit configuration (SPST), number of positions (8), mounting type (through hole, right angle), pitch (0.100"), actuator type (slide standard), and contact material (phosphor bronze with gold finish). Substitute parts must maintain compatibility across these mechanical and electrical interfaces.

The substitute parts are grouped into two categories:

Direct Equivalent (Same Electrical Rating): BD08AV maintains identical electrical specifications (100mA, 5VDC) with the same mechanical form factor. This part differs only in product status (active vs. obsolete) and packaging format.

Functional Equivalent (Different Electrical Rating): KAS2108E and KAS2108ET are E-Switch alternatives with reduced current rating (25mA) and elevated voltage rating (24VDC). These parts share identical mechanical characteristics (8 positions, through hole right angle, 0.100" pitch, slide actuator) but operate within different electrical parameters. Substitution requires circuit-level verification that the lower current capacity and higher voltage rating are compatible with the application.

Parameter Comparison

Engineering Selection Recommendations

BD08AV (C&K): This part is the primary substitute for the obsolete BD08AV2. It maintains identical electrical ratings (100mA, 5VDC), mechanical configuration, and contact specifications. The BD08AV is active in production status with ROHS3 compliance, providing direct compatibility for PCB layouts and circuit designs originally specified for BD08AV2. Packaging is supplied in tube format.

KAS2108E and KAS2108ET (E-Switch): These alternatives are suitable only when circuit requirements permit operation at 24VDC with reduced current capacity (25mA maximum). Both parts maintain the same 8-position SPST configuration, through-hole right-angle mounting, and 0.100" pitch. The KAS2108ET includes tape seal features and washable capability, while KAS2108E does not provide washable characteristics. Both E-Switch alternatives exhibit reduced mechanical and electrical life ratings (2,000 cycles vs. 10,000 cycles), reflecting different design specifications. Selection between KAS2108E and KAS2108ET depends on washability requirements for manufacturing processes.

All substitute parts maintain RoHS3 compliance, MSL 1 rating, and REACH unaffected status, supporting regulatory requirements equivalent to or exceeding the original BD08AV2 specification.

Frequently Asked Questions (FAQ)

Q: Can BD08AV directly replace BD08AV2 in existing designs?

A: Yes. BD08AV maintains identical electrical ratings (100mA, 5VDC), mechanical form factor, pitch (0.100"), and contact materials. PCB layouts and circuit designs require no modification. The primary difference is product status (active vs. obsolete) and packaging format (tube vs. standard).

Q: What are the limitations of KAS2108E and KAS2108ET substitutes?

A: KAS2108E and KAS2108ET operate at 24VDC with maximum current of 25mA, compared to BD08AV2's 5VDC, 100mA rating. Mechanical and electrical life cycles are reduced to 2,000 cycles versus 10,000 cycles. These parts are suitable only for applications where the circuit voltage and current requirements are compatible with the lower electrical specifications.

Q: What is the difference between KAS2108E and KAS2108ET?

A: Both parts share identical electrical and mechanical specifications. KAS2108ET includes tape seal features and washable capability, while KAS2108E does not provide washable characteristics. Selection depends on manufacturing process requirements for cleaning and assembly.

Q: Are all substitute parts RoHS compliant?

A: Yes. BD08AV carries RoHS Compliant status, while KAS2108E and KAS2108ET carry ROHS3 Compliant status. All parts meet current regulatory requirements and are REACH unaffected.

Q: What are the physical dimension differences between substitutes?

A: BD08AV matches BD08AV2 dimensions exactly (0.880" length, 0.380" height). KAS2108E and KAS2108ET are slightly shorter (0.854" length) and taller (0.390" height). These minor variations may affect PCB layout clearances in space-constrained applications.

Q: Do all substitutes maintain the same pitch and mounting configuration?

A: Yes. All substitute parts maintain 0.100" (2.54mm) pitch and through-hole, right-angle mounting with PC pin termination, ensuring compatibility with existing PCB footprints.
