Grayhill 76PSB07S DIP Switch SPST 7-Position Piano Actuator Equivalent & Substitute Parts

Part Overview

The Grayhill 76PSB07S is a through-hole DIP switch featuring a 7-position SPST configuration with piano actuator, rated for 150mA at 30VDC. This component is classified as obsolete, making equivalent and substitute parts necessary for ongoing design support and procurement. The 76PSB07S operates across -40°C to 85°C with 2,000 mechanical and electrical life cycles, utilizing gold-plated copper alloy contacts and thermoplastic housing with tape seal protection.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76PSB07S is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

• Circuit configuration (SPST)
• Number of positions (7)
• Actuator type and level (Piano, Raised)
• Mounting configuration (Through Hole, Right Angle)
• Pitch spacing (0.100" / 2.54mm)
• Termination style (PC Pin)
• Operating temperature range (-40°C to 85°C)

Secondary Compatibility Parameters:

• Current rating must equal or exceed 150mA
• Voltage rating must equal or exceed 30VDC
• Contact finish (Gold preferred for reliability)
• Washable design capability

The 76PSB07ST from Grayhill Inc. qualifies as a direct equivalent substitute, maintaining identical electrical and mechanical specifications while offering active product status and improved RoHS3 compliance. The 194-7MST from CTS Electrocomponents functions as a functional substitute with reduced electrical ratings (50mA at 24VDC), suitable only for applications with lower power requirements.

Engineering Selection Recommendations

Primary Recommendation: 76PSB07ST (Grayhill Inc.)

The 76PSB07ST is the preferred substitute for the obsolete 76PSB07S. This part maintains complete electrical and mechanical equivalence with identical current (150mA) and voltage (30VDC) ratings, matching mechanical life specifications (2,000 cycles), and preserving all dimensional and functional characteristics. The 76PSB07ST holds active product status, ensuring long-term availability and supply chain stability. The upgrade to ROHS3 compliance provides regulatory advantage for new designs and manufacturing environments with RoHS requirements. Both parts share identical Grayhill Series 76 design lineage, minimizing design validation effort.

Secondary Option: 194-7MST (CTS Electrocomponents)

The 194-7MST functions as a functional substitute only for applications with reduced electrical demands. This part is suitable exclusively for circuits requiring maximum 50mA at 24VDC or lower. The 194-7MST offers extended electrical life (7,000 cycles versus 2,000 cycles), providing durability advantage in high-cycle applications within its power rating. The 0.311" height (versus 0.301") introduces minimal PCB layout impact. ROHS3 compliance and active product status support modern procurement requirements. This substitute requires circuit validation to confirm voltage and current compatibility before implementation.

Frequently Asked Questions (FAQ)

Q: Can the 76PSB07ST directly replace the 76PSB07S without circuit modification?

A: Yes. The 76PSB07ST maintains complete electrical and mechanical equivalence to the 76PSB07S across all critical parameters: 150mA current rating, 30VDC voltage rating, 7-position SPST configuration, piano actuator, through-hole right-angle mounting, 0.100" pitch, and identical operating temperature range. No circuit modification is required. The primary difference is product status (active versus obsolete) and RoHS compliance improvement.

Q: Under what conditions can the 194-7MST substitute for the 76PSB07S?

A: The 194-7MST functions as a substitute only when circuit requirements are reduced to 50mA maximum current at 24VDC maximum voltage. The 194-7MST maintains identical mechanical form factor (7-position SPST, piano actuator, through-hole right-angle mounting, 0.100" pitch) and operating temperature range. Applications exceeding 50mA or 24VDC cannot use this substitute. Circuit validation is mandatory before implementation.

Q: What is the impact of the 0.010" height difference between 76PSB07ST and 194-7MST?

A: The 194-7MST height of 0.311" (versus 0.301" for 76PSB07ST) represents a 0.010" increase above the PCB. This minimal difference typically has no impact on standard PCB layouts with normal component spacing. Verification is required only for designs with tight vertical clearance constraints or stacked component arrangements.

Q: Does the 194-7MST's higher electrical life rating (7,000 cycles) offset its lower power rating?

A: No. Electrical life rating applies only within the component's specified operating parameters. The 194-7MST's 7,000-cycle rating is valid only at 50mA and 24VDC. Applications requiring 150mA at 30VDC cannot benefit from this extended life specification, as the 194-7MST is not rated for these conditions. The 76PSB07ST remains the appropriate choice for full-power applications.

Q: What packaging considerations apply to these substitutes?

A: The 76PSB07S ships in bulk packaging. Both substitutes (76PSB07ST and 194-7MST) ship in tube packaging, which provides improved component protection and handling efficiency. Tube packaging is standard for active production parts and offers no functional difference to the end application. Inventory management and component handling procedures may require adjustment to accommodate tube packaging format.

Q: Are there compliance differences between the three parts?

A: Yes. The 76PSB07S is RoHS non-compliant. Both 76PSB07ST and 194-7MST are ROHS3 compliant. All three parts are REACH unaffected and classified as EAR99 for export control purposes. For designs subject to RoHS requirements, either the 76PSB07ST or 194-7MST must be selected. The 76PSB07S is suitable only for legacy systems or applications without RoHS mandates.
