C&K 7101SPHZGI Toggle Switch SPDT Equivalent & Substitute Parts

Part Overview

The C&K 7101SPHZGI is a panel-mount toggle switch with SPDT (Single Pole Double Throw) configuration rated for 5A at 120V AC and 28V DC. This switch features an anti-rotation brass actuator with chrome plating, solder lug termination, and epoxy potting for environmental protection. The part operates across -30°C to 85°C with 100,000 electrical cycles rated life.

The 7101SPHZGI is currently active in production. Equivalent and substitute parts are identified based on matching electrical ratings, mechanical mounting compatibility, and circuit configuration to ensure direct functional replacement in panel-mount applications.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 7101SPHZGI are qualified based on the following critical parameters that determine functional compatibility:

Electrical Compatibility Requirements:

• Circuit configuration must be SPDT
• Switch function must be On-On
• Current rating must meet or exceed 5A (AC/DC)
• Voltage ratings must support minimum 120V AC and 28V DC operation

Mechanical Compatibility Requirements:

• Mounting type must be panel mount
• Panel cutout diameter must be 6.35mm circular
• Bushing thread must be 1/4-40
• Termination style must be solder lug

Environmental Compatibility Requirements:

• Operating temperature range must encompass -30°C to 85°C
• Moisture sensitivity level must be 1 (Unlimited)

Parts meeting all three requirement categories are classified as direct substitutes. Parts with reduced electrical ratings or different mechanical specifications are noted as limited-use alternatives.

Parameter Comparison

Engineering Selection Recommendations

Direct Substitutes (Full Electrical and Mechanical Compatibility):

The E-Switch 100AWSP1T1B1M1QEH and 100SP1T6B11M1QEH meet all electrical and mechanical requirements for direct substitution. Both parts maintain 5A current rating at 120V AC and 28V DC, identical panel cutout and bushing specifications, and operate across the required temperature range. Both are ROHS3 compliant and currently in active production status. The 100AWSP1T1B1M1QEH provides IP67 ingress protection as an additional feature. Electrical life ratings are reduced compared to the 7101SPHZGI (30,000 and 40,000 cycles respectively versus 100,000 cycles).

Limited-Use Alternative:

The E-Switch 100SP1T6B11M1REH shares mechanical compatibility but operates at reduced electrical ratings (0.4VA at 20V AC/DC). This part is suitable only for low-voltage, low-current applications and is not recommended for applications requiring the full 5A at 120V AC specification.

Obsolete Alternative:

The NKK Switches M2012SS1W01 is classified as obsolete. While it meets electrical and mechanical requirements with 6A AC and 4A DC ratings at 125V AC and 30V DC, its obsolete status and reduced electrical life (25,000 cycles) make it unsuitable for new designs. The panel cutout diameter is 6.50mm, requiring panel modification for installation.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100AWSP1T1B1M1QEH replace the C&K 7101SPHZGI in all applications?

A: The 100AWSP1T1B1M1QEH is electrically and mechanically compatible for direct substitution. However, its electrical life rating of 30,000 cycles is lower than the 7101SPHZGI's 100,000 cycles. Applications requiring extended cycle life should account for this difference in maintenance planning.

Q: What is the significance of the panel cutout diameter difference in the NKK M2012SS1W01?

A: The M2012SS1W01 requires a 6.50mm circular cutout versus the 6.35mm specified for the 7101SPHZGI. This 0.15mm difference necessitates panel modification and is not a direct drop-in replacement.

Q: Why is the E-Switch 100SP1T6B11M1REH listed as a limited-use alternative?

A: The 100SP1T6B11M1REH operates at 0.4VA maximum at 20V AC/DC, which is significantly below the 7101SPHZGI's 5A at 120V AC rating. This part is suitable only for low-voltage signal switching applications and cannot handle the full electrical load of the original specification.

Q: Are there RoHS compliance considerations for substitution?

A: The 7101SPHZGI is RoHS non-compliant, while all E-Switch alternatives (100AWSP1T1B1M1QEH, 100SP1T6B11M1QEH, 100SP1T6B11M1REH) are ROHS3 compliant. Applications subject to RoHS requirements should specify E-Switch alternatives.

Q: What does the IP67 rating on the 100AWSP1T1B1M1QEH provide?

A: IP67 classification indicates dust-tight and waterproof operation. The 7101SPHZGI does not specify ingress protection. The 100AWSP1T1B1M1QEH is suitable for applications requiring environmental sealing.

Q: How do electrical life ratings affect component selection?

A: Electrical life indicates the number of switching cycles before performance degradation. The 7101SPHZGI's 100,000-cycle rating supports applications with frequent switching. Substitutes with lower ratings (25,000 to 40,000 cycles) are appropriate for moderate-duty applications with less frequent switching.
