Equivalent & Substitute Parts for 76PGB08ST

Part Overview

The 76PGB08ST is an 8-position DIP switch manufactured by Grayhill Inc., featuring a piano actuator with SPST (Single Pole Single Throw) circuit configuration. This component is rated for 150mA at 30VDC and is designed for through-hole, right-angle mounting applications. The part is currently classified as obsolete, which necessitates identification of active equivalent alternatives to maintain design continuity and ensure supply chain availability for new production and repair applications.

Substitute Part Grouping Explanation

The 76PSB08ST qualifies as a direct functional equivalent to the 76PGB08ST based on strict parameter matching. Both components share identical electrical specifications (SPST circuit, 8 positions, 150mA, 30VDC), mechanical characteristics (piano actuator, through-hole right-angle mounting, 0.100" pitch), and environmental ratings (operating temperature -40°C to 85°C, 2,000 cycle life). The substitution is valid because all critical parameters that determine functional compatibility are identical between the two parts.

The primary distinction between these parts is product status and packaging. The 76PGB08ST is obsolete, while the 76PSB08ST maintains active production status. The 76PSB08ST is supplied in tube packaging, whereas the 76PGB08ST was supplied with tape seal packaging. This packaging difference does not affect electrical or mechanical performance and does not preclude substitution in circuit applications.

Both parts maintain identical compliance certifications (ROHS3, REACH Unaffected, EAR99 ECCN classification) and moisture sensitivity levels (MSL 1 - Unlimited), confirming compatibility for regulated and unrestricted applications.

Parameter Comparison

Engineering Selection Recommendations

The 76PSB08ST is the appropriate substitute for the obsolete 76PGB08ST in all applications where the original part was specified. Selection of the 76PSB08ST is justified on the following engineering grounds:

Product Status and Supply Continuity: The 76PGB08ST is classified as obsolete, creating supply chain risk for new production and field repairs. The 76PSB08ST maintains active production status with confirmed inventory availability (6,892 pieces in stock), ensuring reliable component sourcing.

Functional Equivalence: All electrical and mechanical parameters are identical between the two parts. The 76PSB08ST operates within the same voltage (30VDC) and current (150mA) specifications, maintains identical switching characteristics (SPST, 8 positions), and provides equivalent mechanical performance (2,000 cycle life for both mechanical and electrical operation).

Compliance and Certification: Both parts maintain identical regulatory compliance certifications (ROHS3 Compliant, REACH Unaffected, EAR99 ECCN). Moisture sensitivity levels are identical (MSL 1 - Unlimited), confirming suitability for unrestricted storage and handling conditions.

Physical Compatibility: The 76PSB08ST maintains identical physical dimensions and mounting characteristics (0.100" pitch, 0.301" height above board, through-hole right-angle configuration), ensuring direct PCB compatibility without layout modifications.

Packaging Consideration: The 76PSB08ST is supplied in tube packaging rather than tape seal. This packaging difference does not affect component performance or reliability and does not preclude direct substitution in manufacturing or repair operations.
