Key Parameters

Substitute Part Grouping Explanation

The Grayhill Inc. 94HAC10T is identified as a substitute for the Würth Elektronik 428547320911 based on the following critical parameters:

Matching Parameters:

• Circuit configuration: BCD Complement
• Number of positions: 10
• Current rating: 100mA
• Actuator type: Rotary for Tool
• Actuator level: Flush, Recessed
• Mounting type: Through Hole
• Termination style: PC Pin
• Pitch: 0.100" (2.54mm)
• Contact finish: Gold
• Operating temperature range: -40°C to 85°C
• RoHS3 compliance
• MSL rating: 1 (Unlimited)

Allowable Parameter Variations:

• Voltage rating: 50VDC (substitute) versus 42VDC (main part) — the substitute supports higher voltage operation, maintaining compatibility in applications rated at or below 42VDC
• Height above board: 0.225" (5.72mm) versus 0.144" (3.66mm) — mechanical height difference requires PCB layout verification
• Length: 0.390" (9.91mm) versus 0.291" (7.40mm) — physical footprint variation requires board space confirmation
• Mechanical life: 10,000 cycles (substitute) versus 25,000 steps (main part) — reduced cycle rating in substitute

Parameter Comparison

Engineering Selection Recommendations

Both components meet ROHS3 compliance and REACH unaffected status, qualifying for use in regulated applications. The Würth Elektronik 428547320911 provides higher mechanical life rating at 25,000 steps and maintains a lower profile at 0.144" above board. The Grayhill Inc. 94HAC10T offers higher voltage rating capability at 50VDC and greater inventory availability at 3700 units in stock.

Selection between these parts depends on application-specific requirements: choose the Würth part for applications requiring extended mechanical life or constrained vertical PCB space; select the Grayhill part when higher voltage headroom is beneficial or when inventory lead time is a consideration. Both components support identical circuit logic, current handling, temperature range, and pitch specifications, ensuring functional compatibility in BCD complement switching applications.

Frequently Asked Questions (FAQ)

Q: Can the Grayhill 94HAC10T directly replace the Würth 428547320911 on an existing PCB?

A: Functional replacement is possible with layout verification. The Grayhill part is 0.081" taller (5.72mm vs 3.66mm) and 0.099" longer (9.91mm vs 7.40mm). Confirm available clearance above the component and verify that the increased footprint does not interfere with adjacent components or enclosure constraints.

Q: What is the significance of the voltage rating difference (42VDC vs 50VDC)?

A: The Grayhill substitute is rated for 50VDC operation, providing 8VDC additional margin. Applications operating at or below 42VDC experience no functional impact. The higher rating does not affect performance in lower-voltage circuits.

Q: Does the reduced mechanical life of the Grayhill part (10,000 cycles vs 25,000 steps) affect suitability?

A: Mechanical life reduction is a design trade-off. Evaluate application duty cycle requirements. If the switch is actuated fewer than 10,000 times over its service life, the Grayhill part remains suitable. For high-cycle applications approaching or exceeding 10,000 actuations, the Würth part with 25,000-step rating is preferred.

Q: Are the sealing specifications equivalent between IP67 and "Sealed"?

A: Both designations indicate environmental protection. IP67 explicitly specifies dust-tight and waterproof performance. The Grayhill "Sealed" designation provides equivalent environmental protection for standard industrial applications. Confirm specific ingress protection requirements for critical environments.

Q: Do both parts support the same BCD complement circuit logic?

A: Yes. Both components implement identical 10-position BCD complement switching logic. Circuit behavior, output encoding, and signal compatibility are functionally equivalent.

Q: What packaging format is used for both parts?

A: Both components are supplied in tube packaging, standard for through-hole DIP switches. Tube packaging supports automated handling and component counting for production environments.
