Grayhill 76PSB06S DIP Switch Equivalent & Substitute Parts

Part Overview

The Grayhill 76PSB06S is a 6-position SPST piano DIP switch rated for 150mA at 30VDC with through-hole, right-angle mounting. This component is classified as obsolete, making equivalent substitutes necessary for ongoing production and maintenance applications. The part features gold-plated copper alloy contacts, thermoplastic housing, and operates across -40°C to 85°C. Substitution is required when original inventory is depleted or when design updates to active product lines are preferred.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 76PSB06S is determined by strict parameter matching across electrical and mechanical specifications. The following criteria establish valid substitute relationships:

Primary Substitution Criteria (Must Match):

• Circuit configuration: SPST
• Number of positions: 6
• Actuator type: Piano with raised level
• Mounting type: Through hole, right angle
• Pitch: 0.100" (2.54mm)
• Termination style: PC Pin
• Contact finish: Gold

Electrical Compatibility Criteria:

• Current rating must equal or exceed 150mA
• Voltage rating must equal or exceed 30VDC
• Operating temperature range must encompass -40°C to 85°C or be compatible with application requirements

Mechanical Compatibility Criteria:

• Height above board tolerance: ±0.050" acceptable
• Length tolerance: ±0.050" acceptable
• Washable feature: Required

Substitutes are classified as either Direct (identical electrical and mechanical specifications) or Similar (compatible but with reduced electrical ratings or different compliance status).

Engineering Selection Recommendations

76PSB06ST (Grayhill Inc.) – Recommended Direct Substitute

The 76PSB06ST is the primary equivalent for the obsolete 76PSB06S. Both parts share identical electrical ratings (150mA, 30VDC), mechanical dimensions, and circuit configuration. The 76PSB06ST is currently in active production status with 6,606 units in stock. The primary difference is packaging: the 76PSB06ST is supplied in tube format versus tape seal for the original part. The 76PSB06ST achieves ROHS3 compliance, providing regulatory advantage for new designs. This substitute requires no circuit redesign and maintains full functional compatibility.

194-6MST (CTS Electrocomponents) – Conditional Direct Substitute

The 194-6MST is mechanically and functionally compatible but operates at reduced electrical ratings: 50mA at 24VDC versus the original 150mA at 30VDC. This substitute is suitable only for applications where the circuit current requirement does not exceed 50mA and voltage does not exceed 24VDC. The 194-6MST offers extended electrical life (7,000 cycles) and ROHS3 compliance. Height above board is 0.311" (0.010" greater than original), which may require PCB layout verification. This part is appropriate for low-power switching applications.

1-435802-7 (TE Connectivity ALCOSWITCH) – Similar Substitute for Low-Current Applications

The 1-435802-7 is classified as a similar substitute due to significantly reduced electrical ratings: 25mA at 24VDC. This part is suitable only for applications with current requirements below 25mA and voltage below 24VDC. The 1-435802-7 provides extended mechanical and electrical life (7,000 cycles each) and operates across a wider temperature range (-55°C to 105°C). The part is non-RoHS compliant and REACH-affected. Height above board is 0.290" (0.011" lower than original), requiring PCB layout verification. This substitute is appropriate for ultra-low-power control circuits only.

Frequently Asked Questions (FAQ)

Q: Can the 76PSB06ST directly replace the 76PSB06S without circuit modification?

A: Yes. The 76PSB06ST is a direct equivalent with identical electrical specifications (150mA, 30VDC), circuit configuration (SPST, 6 positions), and mechanical dimensions. No circuit redesign is required. The only difference is packaging format (tube versus tape seal).

Q: What is the key limitation of the 194-6MST substitute?

A: The 194-6MST operates at 50mA maximum current and 24VDC maximum voltage, compared to the original 150mA at 30VDC. This substitute is only valid for applications where circuit current does not exceed 50mA and supply voltage does not exceed 24VDC. If your application requires the full 150mA at 30VDC, the 194-6MST is not suitable.

Q: Is the 1-435802-7 suitable for high-current applications?

A: No. The 1-435802-7 is rated for only 25mA at 24VDC, making it unsuitable for applications requiring the original 150mA specification. This part is limited to ultra-low-power control circuits only.

Q: What are the compliance differences between substitutes?

A: The 76PSB06ST and 194-6MST are ROHS3 compliant, while the original 76PSB06S and 1-435802-7 are non-compliant. For new designs subject to RoHS regulations, the 76PSB06ST is the preferred choice. The 1-435802-7 is REACH-affected, while other parts are REACH-unaffected.

Q: Are there mechanical dimension differences that affect PCB layout?

A: Minor differences exist. The 194-6MST height is 0.311" (0.010" taller than original). The 1-435802-7 height is 0.290" (0.011" shorter than original). The 194-6MST length is 0.686" (0.006" longer than original). These variations may require PCB layout verification, particularly for high-density designs with tight spacing constraints.

Q: What is the difference between mechanical life and electrical life specifications?

A: Mechanical life (2,000 cycles for original; 7,000 cycles for 194-6MST and 1-435802-7) measures actuator durability through physical switch operations. Electrical life (2,000 cycles for original; 7,000 cycles for alternatives) measures contact reliability under electrical load. Both specifications are relevant for long-term reliability assessment.

Q: Can I use the 194-6MST or 1-435802-7 in a 30VDC circuit?

A: No. Both alternatives are rated for 24VDC maximum. Applying 30VDC exceeds their voltage rating and will cause component failure or safety hazard. Use only the 76PSB06ST for 30VDC applications.

Q: Which substitute offers the best long-term reliability?

A: The 194-6MST and 1-435802-7 both offer extended electrical life (7,000 cycles versus 2,000 cycles for the original). However, reliability depends on application-specific current and voltage requirements. For applications matching the original 150mA/30VDC specification, the 76PSB06ST maintains the original reliability profile. For lower-power applications, the alternatives provide extended cycle life.
