Key Parameters

Substitute Part Grouping Explanation

The SH-7050MC from Nidec Components Corporation qualifies as a substitute based on the following critical parameters that determine functional compatibility:

Matching Parameters:

• 16-position configuration
• 100mA current rating
• Rotary tool actuator with flush, recessed actuation level
• Through-hole mounting with 0.100" (2.54mm) pitch
• Gold contact finish
• Hexadecimal circuit configuration
• PC pin termination style
• Washable design capability
• ROHS3 compliance
• MSL 1 (Unlimited) moisture sensitivity rating

Differing Parameters:

• Voltage rating: 5VDC (SH-7050MC) versus 42VDC (RDMAC16P1T)
• Operating temperature range: -40°C ~ 85°C (SH-7050MC) versus -60°C ~ 125°C (RDMAC16P1T)
• Electrical life: 10,000 steps (SH-7050MC) versus 25,000 steps (RDMAC16P1T)
• Height above board: 0.146" (3.70mm) versus 0.144" (3.66mm)
• Length: 0.287" (7.30mm) versus 0.291" (7.40mm)

Substitution is valid only for applications operating at 5VDC with temperature requirements within -40°C to 85°C and electrical cycle requirements not exceeding 10,000 steps.

Parameter Comparison

Engineering Selection Recommendations

Both the RDMAC16P1T and SH-7050MC are active production components with ROHS3 compliance and REACH unaffected status, meeting current regulatory requirements. Selection between these parts depends on application voltage and environmental specifications:

Select RDMAC16P1T when:

• Application voltage is 42VDC
• Operating temperature range extends to -60°C or above 85°C
• Electrical cycle life requirement exceeds 10,000 steps
• Extended mechanical life of 25,000 steps is required

Select SH-7050MC when:

• Application voltage is 5VDC
• Operating temperature range is within -40°C to 85°C
• Electrical cycle life requirement does not exceed 10,000 steps
• Inventory availability is a priority (17,866 units in stock)

Both components share identical mechanical pitch, mounting configuration, and actuator design, ensuring PCB layout compatibility within the specified parameter constraints.

Frequently Asked Questions (FAQ)

Q: Can SH-7050MC replace RDMAC16P1T in a 42VDC application?

A: No. The SH-7050MC is rated for 5VDC operation only. Using it in a 42VDC circuit will result in component failure and potential circuit damage.

Q: Are the physical dimensions interchangeable?

A: The components are mechanically similar with minor dimensional variations. RDMAC16P1T height is 0.144" (3.66mm) and length is 0.291" (7.40mm), while SH-7050MC measures 0.146" (3.70mm) height and 0.287" (7.30mm) length. These differences are within typical PCB tolerance ranges for through-hole mounting at 0.100" pitch.

Q: What is the difference between Hexadecimal and Hexadecimal Complement circuits?

A: Both configurations provide 16-position selection capability. The circuit type designation indicates the specific encoding scheme used for position selection. Both parts support the same number of discrete positions and are functionally equivalent for applications requiring 16-position rotary selection.

Q: Can I use SH-7050MC if my application operates at temperatures below -40°C?

A: No. The SH-7050MC operating temperature range is -40°C to 85°C. For applications requiring operation below -40°C, the RDMAC16P1T with its -60°C to 125°C range is the appropriate selection.

Q: What is the significance of the 25,000 versus 10,000 step electrical life difference?

A: Electrical life represents the number of complete switch cycles the component is rated to perform reliably. RDMAC16P1T supports 25,000 cycles, while SH-7050MC supports 10,000 cycles. Applications requiring frequent position changes should verify cycle requirements against the selected component's rating.

Q: Are both parts washable?

A: Yes. Both RDMAC16P1T and SH-7050MC are rated as washable components, supporting cleaning processes in manufacturing environments.

Q: Do both parts have the same moisture sensitivity level?

A: Yes. Both components carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
