Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following electrical and mechanical parameters:

Primary Substitution Criteria:

Circuit configuration: DPDT
Switch function: On-On
Current rating: 5A (AC/DC) minimum
Voltage rating: 120V AC / 28V DC minimum
Mounting type: Panel Mount
Panel cutout dimensions: Circular 6.35mm Dia
Bushing thread: 1/4-40
Termination style: PC Pin
Operating temperature range: -30°C to 85°C minimum

Secondary Compatibility Factors:

Actuator type (Anti-Rotation preferred for direct replacement)
Actuator length (10.67mm nominal, with tolerance for mechanical fit)
Epoxy sealed terminals (preferred for environmental protection)

Substitute parts are grouped into two categories:

Direct Equivalent (Same Electrical & Mechanical Specifications):

C&K 7201SPYCRE: Active product status, identical electrical ratings, PC Pin termination, anti-rotation actuator

Compatible Alternatives (Meet or Exceed Electrical Requirements):

E-Switch 100 Series: Active products meeting 5A/120V requirements with standard round or flat anti-rotation actuators
Grayhill 34A Series: Active products meeting or exceeding electrical specifications with standard round actuators

Parts with reduced electrical ratings (0.4VA at 20V) are listed for reference but do not meet the primary 5A/120V substitution criteria.

Engineering Selection Recommendations

Recommended Primary Substitute: C&K 7201SPYCRE

The 7201SPYCRE is the optimal substitute for the obsolete 7201SPYCLE. Both parts share identical electrical specifications (5A/120V AC, 28V DC), mechanical dimensions, and termination style. The 7201SPYCRE maintains the same 100,000 electrical cycle rating and anti-rotation actuator design. The primary advantage is active product status with RoHS compliance and REACH affected designation, ensuring long-term availability and regulatory alignment.

Alternative Substitutes for New Designs:

E-Switch 100DP1T6B15M2QEH and Grayhill 34ADP11B3M2QT are suitable alternatives when the 7201SPYCRE is unavailable. Both meet the 5A/120V electrical requirements and share identical panel mounting dimensions and PC Pin termination. These parts feature active product status and ROHS3 compliance. The trade-off is reduced electrical life (40,000 cycles versus 100,000 cycles) and different actuator configurations. The 100DP1T6B15M2QEH uses flat anti-rotation actuator at 12.30mm length, while the 34ADP11B3M2QT uses standard round actuator at 12.19mm length. Mechanical fit verification is required due to actuator length variation.

Compliance Considerations:

The original 7201SPYCLE is RoHS non-compliant. All recommended substitutes (7201SPYCRE, 100DP1T6B15M2QEH, 34ADP11B3M2QT) are RoHS compliant, supporting regulatory requirements for new applications. The 7201SPYCRE is REACH affected, while E-Switch and Grayhill alternatives are REACH unaffected.

Frequently Asked Questions (FAQ)

Q: Can the E-Switch 100DP1T1B1M2QEH directly replace the 7201SPYCLE?

A: The 100DP1T1B1M2QEH meets all electrical specifications (5A/120V AC, 28V DC) and shares identical panel cutout dimensions and bushing thread. However, it uses a standard round actuator at 10.41mm length versus the anti-rotation actuator at 10.67mm on the original part. Mechanical fit verification is required before installation.

Q: What is the significance of the 100,000 versus 40,000 electrical cycle rating?

A: The 7201SPYCLE and 7201SPYCRE are rated for 100,000 electrical cycles, while E-Switch and Grayhill alternatives are rated for 40,000 cycles. This difference affects component lifespan in high-cycle applications. For applications requiring extended cycle life, the 7201SPYCRE is the preferred choice.

Q: Are there termination style differences between substitutes?

A: All recommended substitutes use PC Pin termination, matching the original 7201SPYCLE. The E-Switch 100DP1T1B1M3QEH uses Quick Connect 0.062" (1.5mm) termination and is not recommended as a direct substitute due to this difference.

Q: How do actuator length variations affect panel mounting?

A: The 7201SPYCLE uses a 10.67mm anti-rotation actuator. Substitutes vary: 100DP1T1B1M2QEH at 10.41mm (standard round), 100DP1T6B15M2QEH at 12.30mm (flat anti-rotation), and 34ADP11B3M2QT at 12.19mm (standard round). Longer actuators may require panel cutout adjustment or operator interface redesign. Verify mechanical clearance before substitution.

Q: What is the difference between RoHS Compliant and ROHS3 Compliant?

A: Both designations indicate compliance with RoHS directives. ROHS3 refers to the most recent RoHS 3 directive (2015/863/EU). All recommended substitutes meet current RoHS requirements. The original 7201SPYCLE is RoHS non-compliant and should be replaced in new designs requiring regulatory compliance.

Q: Can parts with 0.4VA at 20V ratings substitute for the 5A/120V original?

A: No. Parts such as 100DP1T1B1M2REH and 34ADP11B1M2RT are rated for 0.4VA at 20V, which does not meet the 5A/120V requirement of the 7201SPYCLE. These parts are listed in cross-reference data but are not suitable substitutes for this application.

Q: Is the 7201SPYCRE available in bulk packaging?

A: The 7201SPYCRE is available with 645 pieces in stock. Packaging specifications are not detailed in the provided data. Contact the supplier for packaging options and lead times.
