Key Parameters

Substitute Part Grouping Explanation

Substitution of the M83504/01-030 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility Requirements:

• Circuit configuration must remain SPST
• Current rating must equal or exceed 150mA
• Voltage rating must equal or exceed 30VDC

Mechanical Compatibility Requirements:

• Number of positions must equal 10
• Actuator type must be rocker
• Mounting type must be through hole
• Pitch must be 0.100" (2.54mm)
• Height above board must be 0.315" (8.00mm)

Material and Environmental Requirements:

• Contact material must be copper alloy with gold finish
• Operating temperature range must encompass -40°C to 85°C
• Mechanical and electrical life must meet or exceed 2,000 cycles

The substitute part 76SB10ST meets all these criteria and is derived from the same Grayhill 76 series platform.

Parameter Comparison

Engineering Selection Recommendations

The 76SB10ST is the direct functional equivalent of the M83504/01-030 for all electrical and mechanical applications. Selection between these parts should be based on the following factors:

Product Status Consideration: The M83504/01-030 is classified as obsolete. The 76SB10ST maintains active product status with Grayhill Inc., ensuring continued availability and manufacturing support.

Regulatory Compliance: The M83504/01-030 is RoHS non-compliant. The 76SB10ST is ROHS3 compliant, meeting current environmental and regulatory requirements for new designs and systems subject to RoHS directives.

Packaging Format: The M83504/01-030 is supplied in tape packaging. The 76SB10ST is supplied in tube packaging. Packaging selection depends on assembly process requirements and handling procedures.

Functional Equivalence: All electrical parameters, mechanical dimensions, contact materials, and environmental ratings are identical between the two parts. Direct substitution is supported without circuit or layout modifications.

Frequently Asked Questions (FAQ)

Q: Can the 76SB10ST be used as a direct replacement for the M83504/01-030 in existing designs?

A: Yes. The 76SB10ST is functionally equivalent across all electrical and mechanical parameters. No circuit modifications or PCB layout changes are required. The only difference is packaging format (tube versus tape) and improved RoHS3 compliance status.

Q: What is the difference between the tape and tube packaging formats?

A: Tape packaging (M83504/01-030) uses a continuous carrier tape suitable for automated pick-and-place assembly. Tube packaging (76SB10ST) uses a rigid tube container suitable for manual handling and bulk storage. Selection depends on assembly process capabilities and inventory management requirements.

Q: Why is the M83504/01-030 classified as obsolete?

A: Obsolescence classification indicates that Grayhill Inc. has discontinued active production and support for this specific part number. The 76SB10ST represents the current active equivalent within the Grayhill 76 series platform.

Q: Are there any electrical performance differences between these parts?

A: No. Both parts are rated for 150mA at 30VDC with identical contact materials, mechanical life ratings, and electrical life ratings. Performance in circuit operation is equivalent.

Q: Does the RoHS3 compliance of the 76SB10ST affect compatibility?

A: RoHS3 compliance indicates improved environmental and material standards. This does not affect electrical or mechanical compatibility. For systems subject to RoHS regulations, the 76SB10ST is the required selection.

Q: What is the pitch specification and why is it important?

A: Pitch is the center-to-center distance between adjacent switch positions, specified as 0.100" (2.54mm). This dimension determines PCB footprint compatibility. Both parts share identical pitch specifications, ensuring direct PCB compatibility.

Q: Can these switches be used in washable applications?

A: Yes. Both the M83504/01-030 and 76SB10ST are rated as washable, supporting cleaning processes in manufacturing environments.
