SP08AB DIP Switch SPST 8 Position Equivalent & Substitute Parts

Part Overview

The SP08AB is a DIP switch SPST (Single Pole Single Throw) with 8 positions, rated for 10mA at 20VDC. This component features a through-hole, right-angle mounting configuration with slide actuator and gold-plated beryllium copper contacts. The SP08AB is classified as obsolete, making identification of compatible substitute parts essential for ongoing system support and new design implementations.

Substitute Part Grouping Explanation

Substitution eligibility for the SP08AB is determined by strict equivalence across the following critical parameters:

• Circuit configuration: SPST topology
• Position count: 8 positions
• Electrical ratings: 10mA current, 20VDC voltage minimum
• Actuator mechanism: Slide (Standard) type
• Mounting configuration: Through hole, right angle orientation
• Contact specifications: Beryllium copper with gold finish
• Pitch spacing: 0.100" (2.54mm)

The SPA08AB meets all substitution criteria as a direct equivalent from C&K, maintaining identical electrical and mechanical specifications while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The SPA08AB is the direct substitute for the obsolete SP08AB. Both components share identical electrical and mechanical specifications, ensuring functional equivalence in circuit applications. The SPA08AB offers the advantage of active product status, providing assured long-term availability and supply chain continuity.

The SPA08AB achieves ROHS3 compliance, whereas the SP08AB is RoHS non-compliant. This distinction is significant for applications subject to RoHS regulatory requirements. Both components maintain identical REACH and ECCN classifications.

Physical dimensions differ marginally: the SPA08AB length is 0.942" (23.92mm) compared to the SP08AB at 0.898" (22.82mm). Operating temperature ranges also differ—the SPA08AB operates from -30°C to 60°C, while the SP08AB operates from -20°C to 85°C. These variations require verification against specific application requirements.

Frequently Asked Questions (FAQ)

Q: Can the SPA08AB directly replace the SP08AB in existing designs?

A: The SPA08AB is electrically and mechanically equivalent to the SP08AB across all critical parameters: SPST circuit, 8 positions, 10mA/20VDC ratings, slide actuator, through-hole right-angle mounting, and identical pitch spacing. Physical dimensions and operating temperature ranges differ slightly and must be evaluated against specific application constraints.

Q: What is the primary reason to substitute the SP08AB?

A: The SP08AB is classified as obsolete. The SPA08AB provides an active, in-production alternative from the same manufacturer with identical functional specifications.

Q: Are there packaging differences between SP08AB and SPA08AB?

A: The SP08AB packaging is listed as standard, while the SPA08AB is supplied in tube packaging. This distinction affects handling, storage, and component dispensing procedures.

Q: Does the SPA08AB meet modern compliance standards?

A: The SPA08AB is ROHS3 compliant, whereas the SP08AB is RoHS non-compliant. Both maintain REACH Unaffected status and EAR99 export classification.

Q: Are there operating temperature limitations when substituting?

A: The SPA08AB operates within -30°C to 60°C, while the SP08AB operates within -20°C to 85°C. Applications requiring operation above 60°C or below -30°C must retain the original SP08AB specification or identify alternative components.
