Grayhill 76SB06S DIP Switch Rocker SPST 150mA 30V Equivalent & Substitute Parts

Part Overview

The Grayhill 76SB06S is a 6-position DIP switch with rocker actuator, rated for 150mA at 30VDC, designed for through-hole PCB mounting. This component is classified as obsolete product status. Identification of equivalent and substitute parts is necessary to support ongoing production requirements, maintenance operations, and design continuity where the original part is no longer readily available or where alternative compliance certifications are required.

Substitute Part Grouping Explanation

Substitution eligibility for the 76SB06S is determined by the following critical parameters: circuit configuration (SPST), number of positions (6), mounting type (through hole), pitch (0.100"), and contact finish (gold). Current rating and voltage rating establish the maximum electrical operating envelope. Actuator type (rocker vs. slide) and product status (active vs. obsolete) define functional and availability categories.

Direct Equivalent Criteria: Parts must maintain identical circuit configuration, position count, mounting type, pitch, and contact finish. Current and voltage ratings must equal or exceed the original specification. Actuator type should match for form-factor compatibility.

Acceptable Substitute Criteria: Parts may deviate in actuator type, current rating (if lower, application-dependent), voltage rating (if lower, application-dependent), or compliance status, provided the core electrical and mechanical interfaces remain compatible with the PCB footprint and circuit requirements.

The following substitutes are classified based on these parameters:

76SB06ST (Grayhill): Direct equivalent with active product status and improved RoHS3 compliance
206-6ST (CTS Electrocomponents): Functional substitute with different actuator type (slide) and reduced electrical ratings
3-435640-7 (TE Connectivity ALCOSWITCH): Functional substitute with rocker actuator but significantly reduced voltage and current ratings

Engineering Selection Recommendations

Primary Recommendation: Grayhill 76SB06ST

The 76SB06ST is the preferred substitute for the obsolete 76SB06S. Both parts are manufactured by Grayhill Inc. and share identical electrical specifications (150mA, 30VDC), circuit configuration (SPST), position count (6), actuator type (rocker), and mechanical interface parameters (pitch, mounting type, height above board). The 76SB06ST maintains active product status and achieves RoHS3 compliance, addressing regulatory requirements that the original part does not meet. Packaging is supplied in tube format rather than tape seal, which may require adjustment to assembly processes but does not affect electrical or mechanical compatibility.

Secondary Recommendation: CTS Electrocomponents 206-6ST

The 206-6ST is an acceptable functional substitute where application requirements permit reduced electrical ratings. This part maintains the 6-position SPST configuration, through-hole mounting, and 0.100" pitch. However, the current rating is reduced to 50mA (from 150mA) and voltage rating is reduced to 24VDC (from 30VDC). The actuator type differs (slide vs. rocker), which affects user interface and PCB footprint compatibility. The 206-6ST offers extended electrical life (10,000 cycles vs. 2,000 cycles) and RoHS3 compliance. Selection of this part requires verification that the application circuit operates within the reduced electrical envelope and that the slide actuator form factor is acceptable for the end-use design.

Tertiary Recommendation: TE Connectivity ALCOSWITCH 3-435640-7

The 3-435640-7 is a functional substitute only for applications with significantly reduced electrical requirements. This part maintains the rocker actuator type and 6-position SPST configuration but is rated for only 60mA at 5VDC, making it unsuitable for the original 150mA/30VDC specification. The operating temperature range extends to 105°C, which may be beneficial in high-temperature environments. RoHS compliance status is non-compliant, matching the original part. Selection of this part is limited to applications where the circuit operates at 5VDC or lower and current draw does not exceed 60mA.

Frequently Asked Questions (FAQ)

Q: Can the 76SB06ST be used as a direct replacement for the 76SB06S without PCB modification?

A: Yes. The 76SB06ST maintains identical electrical specifications, circuit configuration, position count, pitch (0.100"), mounting type (through hole), and height above board (0.315"). No PCB layout changes are required. The primary difference is packaging format (tube vs. tape seal), which affects component handling and assembly processes but not electrical or mechanical compatibility.

Q: What is the primary reason the 76SB06S is classified as obsolete?

A: The 76SB06S is obsolete due to its RoHS non-compliant status. The 76SB06ST, its active equivalent, achieves RoHS3 compliance while maintaining identical electrical and mechanical specifications. For new designs or products subject to RoHS regulations, the 76SB06ST is the appropriate selection.

Q: Can the 206-6ST (CTS) be used in place of the 76SB06S in a 30VDC/150mA circuit?

A: No. The 206-6ST is rated for 24VDC maximum and 50mA maximum. Using this part in a circuit designed for 30VDC/150mA would exceed the component's electrical ratings and create a reliability risk. The 206-6ST is suitable only for applications operating at 24VDC or lower with current draw not exceeding 50mA.

Q: What is the difference between rocker and slide actuators in DIP switches?

A: Rocker actuators (76SB06S, 76SB06ST, 3-435640-7) feature a lever-type mechanism that rocks back and forth to toggle switch positions. Slide actuators (206-6ST) use a sliding mechanism to select positions. The actuator type affects the physical form factor, user interface feel, and PCB footprint. While both types maintain the same 0.100" pitch and through-hole mounting, the actuator profile differs, which may affect enclosure design and user accessibility.

Q: Is the 3-435640-7 suitable for replacing the 76SB06S in existing designs?

A: The 3-435640-7 is not suitable as a direct replacement for the 76SB06S in designs operating at 30VDC/150mA. The 3-435640-7 is rated for only 5VDC/60mA. This part is appropriate only for low-voltage, low-current applications (5VDC or lower, 60mA or lower). If your application requires 30VDC/150mA operation, the 76SB06ST is the correct choice.

Q: What compliance certifications differ between the substitute parts?

A: The 76SB06ST and 206-6ST both achieve RoHS3 compliance, addressing modern regulatory requirements. The original 76SB06S and the 3-435640-7 are RoHS non-compliant. All parts listed are REACH Unaffected or REACH Affected (3-435640-7 only) and carry EAR99 ECCN classification. For applications subject to RoHS regulations, the 76SB06ST or 206-6ST are required.

Q: How do mechanical and electrical life ratings affect part selection?

A: The 76SB06S, 76SB06ST, and 3-435640-7 all specify 2,000 mechanical and electrical cycles. The 206-6ST specifies 10,000 electrical cycles with mechanical life not specified. In applications requiring frequent switch actuation, the 206-6ST offers extended electrical life. However, if the application requires only occasional switching, all parts meet the requirement. Mechanical life is determined by the actuator mechanism durability; electrical life is determined by contact material and design.

Q: Can packaging format (tape seal vs. tube vs. bulk) affect electrical performance?

A: No. Packaging format affects component handling, storage, and assembly process compatibility but does not affect electrical performance or specifications. The 76SB06S (tape seal), 76SB06ST (tube), and 206-6ST (tube) are electrically equivalent within their respective rating specifications. Bulk packaging (3-435640-7) is suitable for high-volume assembly operations where components are manually placed or used with specialized handling equipment.
