Grayhill 76PSB10 DIP Switch Equivalent & Substitute Parts

Part Overview

The Grayhill 76PSB10 is a 10-position SPST piano DIP switch rated for 150mA at 30VDC with through-hole, right-angle mounting. This component is classified as obsolete product status. Identification of equivalent and substitute parts is necessary to support ongoing maintenance, repair, and new design requirements where the original part is no longer in active production or inventory allocation is constrained.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the 76PSB10 is evaluated based on strict electrical and mechanical parameter compatibility. The following criteria determine valid substitution:

Primary Compatibility Criteria:

• Circuit configuration: SPST
• Number of positions: 10
• Mounting type: Through hole, right angle
• Pitch: 0.100" (2.54mm)
• Actuator type: Piano with raised level
• Contact material and finish: Copper alloy with gold finish
• Termination style: PC pin

Electrical Compatibility Criteria:

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

Mechanical Compatibility Criteria:

• Height above board and overall length must be compatible with PCB layout
• Mechanical and electrical life ratings must support application requirements

Substitutes are classified into two categories: direct equivalents (identical electrical and mechanical specifications) and similar alternatives (compatible but with parameter variations requiring application verification).

Engineering Selection Recommendations

76PSB10T (Direct Equivalent - Recommended Primary Substitute)

The 76PSB10T is the direct functional equivalent of the 76PSB10. Both parts share identical electrical ratings (150mA, 30VDC), mechanical specifications (10 positions, piano actuator, through-hole right-angle mounting), and operating temperature range (-40°C to 85°C). The 76PSB10T is in active product status with RoHS3 compliance, addressing regulatory requirements for new designs and production. Packaging is supplied in tube format. This part is suitable for direct replacement in all applications where the 76PSB10 was originally specified.

435802-8 (Similar Alternative - Conditional Use)

The TE Connectivity ALCOSWITCH 435802-8 shares the same circuit configuration, position count, mounting type, and pitch as the 76PSB10. However, this part has reduced electrical ratings (25mA at 24VDC compared to 150mA at 30VDC) and is therefore suitable only for applications with lower power requirements. The 435802-8 offers extended mechanical and electrical life (7,000 cycles versus 2,000 cycles) and a wider operating temperature range (-55°C to 105°C). This part is not suitable for applications requiring the full 150mA current capacity or 30VDC voltage rating of the original 76PSB10.

Compliance Considerations

The 76PSB10 is RoHS non-compliant. For new designs subject to RoHS regulations, the 76PSB10T (RoHS3 compliant) is the appropriate selection. The 435802-8 remains RoHS non-compliant and is not suitable for RoHS-regulated applications.

Frequently Asked Questions (FAQ)

Q: Can the 76PSB10T be used as a direct replacement for the 76PSB10?

A: Yes. The 76PSB10T is electrically and mechanically identical to the 76PSB10. Both parts have 150mA current rating, 30VDC voltage rating, 10 SPST positions, piano actuator, through-hole right-angle mounting, and identical pitch and height specifications. The primary difference is product status (76PSB10T is active) and RoHS compliance (76PSB10T is RoHS3 compliant).

Q: Is the 435802-8 a suitable replacement for the 76PSB10?

A: The 435802-8 is not suitable for direct replacement. While it shares the same circuit configuration, position count, and mounting type, it has significantly lower electrical ratings (25mA versus 150mA current, 24VDC versus 30VDC voltage). Use the 435802-8 only in applications with lower power requirements that do not exceed 25mA at 24VDC.

Q: What is the difference between the 76PSB10 and 76PSB10T packaging?

A: The 76PSB10 is supplied in bulk packaging, while the 76PSB10T is supplied in tube packaging. Both parts are identical in form, fit, and function. Tube packaging may provide improved handling and traceability for production environments.

Q: Does the 76PSB10T meet RoHS requirements?

A: Yes. The 76PSB10T is RoHS3 compliant. The original 76PSB10 is RoHS non-compliant. For applications subject to RoHS regulations, the 76PSB10T is the appropriate selection.

Q: What is the mechanical life difference between the 76PSB10 and 435802-8?

A: The 76PSB10 has a mechanical life rating of 2,000 cycles. The 435802-8 has a mechanical life rating of 7,000 cycles. The 435802-8 offers extended durability but is limited by its lower electrical ratings (25mA, 24VDC).

Q: Can I use the 435802-8 in a high-current application rated for 150mA?

A: No. The 435802-8 is rated for maximum 25mA continuous current. Using this part in a 150mA application will result in contact failure and unsafe operation. The 76PSB10T must be used for applications requiring 150mA capacity.

Q: Are there any height or footprint differences between these parts?

A: The 76PSB10 and 76PSB10T have identical height (0.301" / 7.65mm) and length (1.080" / 27.43mm). The 435802-8 has a slightly lower height (0.290" / 7.37mm) but identical length. All three parts have the same 0.100" (2.54mm) pitch and are compatible with standard DIP switch PCB layouts.
