SP10AB DIP Switch - Equivalent & Substitute Parts

Part Overview

The SP10AB is a 10-position DIP switch manufactured by C&K, designed for through-hole, right-angle mounting applications requiring SPST (Single Pole Single Throw) switching at 10mA and 20VDC. This component features beryllium copper contacts with gold finish, polyphenylene sulfide housing, and a 0.100" pitch configuration suitable for standard PCB layouts.

The SP10AB is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain design continuity, ensure component availability, and support ongoing production or repair requirements for legacy systems utilizing this switch configuration.

Substitute Part Grouping Explanation

Substitution eligibility for the SP10AB is determined by strict equivalence across the following critical parameters:

• Circuit Configuration: SPST topology must be maintained
• Position Count: 10-position requirement
• Electrical Ratings: 10mA current and 20VDC voltage ratings
• Mechanical Interface: Through-hole, right-angle mounting with 0.100" pitch
• Contact System: Beryllium copper with gold finish
• Housing Material: Polyphenylene Sulfide (PPS)
• Termination: PC pin configuration

The SPA10AB meets all substitution criteria, maintaining identical electrical and mechanical specifications while offering improved product status and compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

The SPA10AB is the direct substitute for the obsolete SP10AB. Both components share identical electrical and mechanical specifications, ensuring functional compatibility in existing circuit designs. The SPA10AB provides the additional advantage of active product status, ensuring continued availability and supply chain support.

The SPA10AB carries ROHS3 compliance certification, whereas the SP10AB is non-compliant. For applications subject to RoHS regulatory requirements, the SPA10AB is the appropriate selection. Both components maintain REACH unaffected status.

Physical dimensions differ marginally: the SPA10AB length is 1.142" (29.01mm) compared to the SP10AB at 1.098" (27.89mm). Operating temperature ranges also differ—the SPA10AB operates from -30°C to 60°C, while the SP10AB operates from -20°C to 85°C. These variations require verification against specific application thermal and spatial constraints.

Frequently Asked Questions (FAQ)

Q: Can the SPA10AB directly replace the SP10AB in existing designs?

A: The SPA10AB maintains identical electrical ratings (10mA, 20VDC), circuit configuration (SPST), position count (10), and mechanical interface (through-hole, right-angle, 0.100" pitch). Functional substitution is supported. Physical dimension and operating temperature range differences require design verification.

Q: What is the primary reason for substituting the SP10AB?

A: The SP10AB is classified as obsolete. The SPA10AB provides equivalent functionality with active product status, ensuring component availability and supply chain continuity.

Q: Are there packaging differences between SP10AB and SPA10AB?

A: The SP10AB packaging is listed as standard (-), while the SPA10AB is supplied in tube packaging. Tube packaging is standard for active production components and does not affect electrical or mechanical performance.

Q: Does the SPA10AB meet regulatory compliance requirements?

A: The SPA10AB is ROHS3 compliant and REACH unaffected. The SP10AB is RoHS non-compliant. For applications requiring RoHS compliance, the SPA10AB is the appropriate selection.

Q: What are the operating temperature differences?

A: The SP10AB operates from -20°C to 85°C. The SPA10AB operates from -30°C to 60°C. Applications requiring operation above 60°C or below -30°C require design review to confirm compatibility with the SPA10AB temperature range.

Q: Are the physical dimensions identical?

A: Height above board is identical at 0.169" (4.30mm). Length differs: SP10AB is 1.098" (27.89mm), while SPA10AB is 1.142" (29.01mm). PCB layout verification is required to confirm spatial compatibility.
