Equivalent & Substitute Parts for 76RSB09ST

Part Overview

The 76RSB09ST is a DIP rocker switch manufactured by Grayhill Inc., featuring SPST (Single Pole Single Throw) circuit configuration with 9 positions. This component is rated for 150mA at 30VDC and is designed for through-hole mounting applications. The product is currently classified as obsolete, making identification of suitable substitute components essential for ongoing design support and production continuity. The 76RSB09ST remains available in inventory with 1104 pieces in stock, though its obsolete status necessitates evaluation of active alternative products for new designs and long-term supply chain planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76RSB09ST is determined by strict alignment with the following critical electrical and mechanical parameters:

Electrical Parameters:

• Circuit configuration: SPST
• Current rating: 150mA minimum
• Voltage rating: 30VDC minimum

Mechanical Parameters:

• Actuator type: Rocker
• Mounting type: Through hole
• Pitch: 0.100" (2.54mm)
• Contact material: Copper alloy with gold finish
• Operating temperature range: -40°C to 85°C

Compliance Parameters:

• RoHS compliance status
• Moisture sensitivity level: 1 (Unlimited)

The 76RSB10ST qualifies as a substitute based on matching all critical electrical parameters, identical mechanical mounting characteristics, and equivalent environmental specifications. The primary distinction is the increased number of positions (10 versus 9) and corresponding length variation, which represents a functional enhancement rather than a limitation for substitution purposes.

Parameter Comparison

Engineering Selection Recommendations

The 76RSB10ST is the qualified substitute for the 76RSB09ST based on the following engineering criteria:

Electrical Compatibility: Both components maintain identical SPST circuit configuration, 150mA current rating, and 30VDC voltage rating. Electrical performance parameters are fully matched.

Mechanical Compatibility: Mounting characteristics are equivalent, including through-hole termination, 0.100" pitch spacing, and identical height above board (0.292"). The 76RSB10ST accommodates one additional position with a 0.100" length increase (27.43mm versus 24.89mm), which requires PCB layout verification but does not compromise functional compatibility.

Compliance Status: The 76RSB10ST carries ROHS3 compliance, representing an advancement over the RoHS Compliant status of the 76RSB09ST. Both components maintain REACH Unaffected status and identical moisture sensitivity classification (MSL 1).

Product Status Consideration: The 76RSB09ST is classified as obsolete, while the 76RSB10ST maintains active product status with higher inventory availability (1653 pieces versus 1104 pieces). For new designs and long-term supply chain requirements, the 76RSB10ST is the appropriate selection.

Frequently Asked Questions (FAQ)

Q: Can the 76RSB10ST directly replace the 76RSB09ST in existing designs?

A: The 76RSB10ST is electrically and mechanically compatible with the 76RSB09ST for applications requiring SPST switching at 150mA and 30VDC. The primary consideration is the increased length (0.100" additional), which requires verification that PCB layout accommodates the larger footprint. All electrical parameters, mounting pitch, and environmental specifications are identical.

Q: What is the significance of the position count difference (9 versus 10)?

A: The position count refers to the number of discrete switch positions available on the DIP switch array. The 76RSB10ST provides one additional position compared to the 76RSB09ST. This difference does not affect electrical performance or switching characteristics; it only impacts the physical length of the component and the number of available switch positions for configuration purposes.

Q: Are there packaging differences between these components?

A: The 76RSB09ST is supplied without specified packaging designation, while the 76RSB10ST is packaged in tube format. Both components feature identical tape seal features and are suitable for automated assembly processes. Packaging format should be confirmed with procurement requirements for your specific application.

Q: Why is the 76RSB09ST classified as obsolete?

A: Product obsolescence is determined by manufacturer lifecycle decisions. The 76RSB10ST, as an active product in the same series with superior compliance status (ROHS3), represents the current generation equivalent. For new designs and ongoing production, the 76RSB10ST is the recommended selection.

Q: Are the RoHS compliance levels functionally different?

A: Both RoHS Compliant and ROHS3 Compliant designations indicate compliance with Restriction of Hazardous Substances regulations. ROHS3 represents the current regulatory standard. From a functional and electrical standpoint, both components meet hazardous substance restrictions. The ROHS3 designation on the 76RSB10ST indicates alignment with current regulatory requirements.

Q: What are the mechanical life specifications for both components?

A: Both the 76RSB09ST and 76RSB10ST are rated for 2,000 mechanical cycles and 2,000 electrical cycles. These specifications are identical and indicate equivalent durability and operational lifespan under specified conditions.
