Grayhill 76RSB06 DIP Switch Rocker SPST Equivalent & Substitute Parts

Part Overview

The Grayhill 76RSB06 is a single-pole single-throw (SPST) DIP switch with rocker actuator, rated for 150mA at 30VDC. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement. The 76RSB06 features a 6-position through-hole configuration with gold-plated copper alloy contacts and operates across a temperature range of -40°C to 85°C. Identification of compatible alternatives ensures design continuity and supply chain reliability for applications requiring equivalent electrical and mechanical characteristics.

Identified Substitute Parts:

76RSB06T (Grayhill Inc.) – Direct equivalent with identical electrical and mechanical specifications. Differs only in packaging (tube versus bulk) and product status (active versus obsolete). RoHS3 compliance provides regulatory advantage over the original 76RSB06.

435668-5 (TE Connectivity ALCOSWITCH Switches) – Functionally equivalent in circuit configuration, positions, actuator type, mounting, and pitch. However, this part operates at reduced current (60mA) and voltage (5VDC) ratings, making it suitable only for applications with lower power requirements than the original 76RSB06 specification.

Engineering Selection Recommendations

For Direct Replacement (Full Electrical and Mechanical Compatibility):

The 76RSB06T is the primary substitute for the obsolete 76RSB06. Both parts are manufactured by Grayhill Inc. and share identical electrical ratings (150mA, 30VDC), mechanical dimensions, and operational characteristics. The 76RSB06T is currently in active production status, ensuring long-term availability. The primary advantage of 76RSB06T is RoHS3 compliance, which satisfies modern regulatory requirements that the original 76RSB06 does not meet. Packaging differs (tube versus bulk), but this does not affect functional performance.

For Reduced-Power Applications Only:

The 435668-5 from TE Connectivity ALCOSWITCH is functionally compatible in terms of circuit topology, position count, actuator design, and mounting configuration. However, this part is rated for only 60mA at 5VDC, representing a significant reduction from the 76RSB06 specification of 150mA at 30VDC. The 435668-5 is suitable only for applications where the actual operating current and voltage requirements are within its lower ratings. This part offers an extended operating temperature range (-55°C to 105°C) compared to the 76RSB06 (-40°C to 85°C), which may be advantageous in extreme temperature environments with reduced power demands.

Frequently Asked Questions (FAQ)

Q: Can the 76RSB06T be used as a direct replacement for the 76RSB06?

A: Yes. The 76RSB06T is a direct functional equivalent with identical electrical ratings (150mA, 30VDC), circuit configuration (SPST), position count (6), actuator type (rocker), mounting method (through hole), and mechanical dimensions. The only differences are packaging format (tube instead of bulk) and product status (active instead of obsolete). RoHS3 compliance of the 76RSB06T provides regulatory advantage.

Q: Is the 435668-5 a suitable replacement for the 76RSB06?

A: The 435668-5 is mechanically and topologically compatible but electrically limited. It operates at 60mA and 5VDC, compared to the 76RSB06 specification of 150mA and 30VDC. Use the 435668-5 only if your application requires no more than 60mA at 5VDC. For applications requiring the full 150mA at 30VDC rating, the 435668-5 is not suitable.

Q: What are the key parameters that determine substitution compatibility?

A: Substitution compatibility is determined by: SPST circuit configuration, 6-position count, rocker actuator with flush/recessed level, through-hole mounting, 0.100" pitch, copper alloy contacts with gold finish, and mechanical/electrical life of 2,000 cycles minimum. Current and voltage ratings must meet or exceed the application requirement.

Q: Does packaging format affect electrical performance?

A: No. The difference between bulk and tube packaging is logistical only. Both 76RSB06 (bulk) and 76RSB06T (tube) are electrically and mechanically identical. Packaging choice depends on procurement and inventory management requirements, not functional performance.

Q: What is the significance of RoHS3 compliance on the 76RSB06T?

A: RoHS3 compliance indicates the 76RSB06T meets current European Union Restriction of Hazardous Substances regulations. The original 76RSB06 is marked as non-compliant. For applications subject to RoHS requirements or future regulatory transitions, the 76RSB06T is the appropriate choice.

Q: Can I use the 435668-5 in a high-voltage application?

A: No. The 435668-5 is rated for 5VDC maximum. Applications requiring 30VDC operation must use either the 76RSB06 or 76RSB06T. Using the 435668-5 at voltages exceeding its rating will result in component failure.

Q: Are there any mechanical dimension differences between these parts?

A: The 76RSB06 and 76RSB06T are mechanically identical with height above board of 0.292" (7.41mm) and length of 0.680" (17.27mm). The 435668-5 has a height of 0.290" (7.37mm), a negligible difference of 0.002" that does not affect PCB layout compatibility for standard through-hole applications.

Q: What is the operating temperature range for each part?

A: The 76RSB06 and 76RSB06T operate from -40°C to 85°C. The 435668-5 operates from -55°C to 105°C, providing a wider temperature envelope. However, temperature range selection should be based on actual application requirements, not as a primary substitution criterion.
