Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the CKL12ATW01-034 are identified within the NKK Switches CKL12ATW base product family. Substitution is valid when the following critical parameters remain identical:

• Circuit configuration: SPDT
• Number of positions: 2
• Switch function: On-On
• Contact timing: Non-Shorting (BBM)
• Current rating: 3A (AC)
• Voltage rating: 250 V AC
• Actuator type: Tubular Key
• Mounting type: Panel Mount
• Termination style: Solder Lug
• Panel cutout dimensions: Circular 19.00mm Dia
• Operating temperature range: -25°C ~ 70°C
• Mechanical life: 30,000 Cycles
• Electrical life: 10,000 Cycles
• Contact material: Silver (Ag)
• RoHS compliance: ROHS3 Compliant

The identified substitutes (CKL12ATW01-001 and CKL12ATW01-037) maintain all specified electrical and mechanical parameters, differing only in manufacturing lot designation or key configuration variant codes. These parts are direct functional equivalents suitable for component replacement in existing designs.

Parameter Comparison

Engineering Selection Recommendations

All three parts (CKL12ATW01-034, CKL12ATW01-001, and CKL12ATW01-037) maintain Active product status with identical electrical and mechanical specifications. Each part carries ROHS3 compliance certification and REACH unaffected designation, meeting current regulatory requirements for industrial and commercial applications. Selection among these equivalents may be based on inventory availability and lead time considerations, as all parts are functionally interchangeable within the specified operating parameters and environmental conditions.

Frequently Asked Questions (FAQ)

Q: Are CKL12ATW01-001 and CKL12ATW01-037 direct replacements for CKL12ATW01-034?

A: Yes. All three parts share identical electrical ratings (3A AC at 250V), circuit configuration (SPDT), mechanical specifications (30,000 cycle mechanical life, 10,000 cycle electrical life), and physical dimensions (19.00mm circular panel cutout, 34.60mm depth). They are functionally interchangeable.

Q: What determines substitution eligibility for CKL12ATW keylock switches?

A: Substitution is valid when circuit configuration, contact timing, current and voltage ratings, actuator type, mounting method, termination style, panel cutout dimensions, operating temperature range, and lifecycle ratings remain unchanged. All identified substitutes maintain these critical parameters.

Q: Do these parts require different PCB layouts or panel modifications?

A: No. All three parts feature identical panel cutout dimensions (Circular 19.00mm Dia), depth behind flange (34.60mm), and solder lug termination style. No design modifications are required for component substitution.

Q: Are there compliance differences between these substitute parts?

A: No. All parts carry identical RoHS3 compliance status, REACH unaffected designation, MSL rating (1 - Unlimited), ECCN classification (EAR99), and HTSUS code (8536.50.9020).

Q: What is the operational difference between these keylock switch variants?

A: The identified substitutes differ only in manufacturing lot designation or key configuration variant codes. All maintain identical operational characteristics, including On-On switch function, non-shorting contact timing (BBM), and key removability from all positions.
