B22KP-AG Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The B22KP-AG is an NKK Switches toggle switch with DPDT (Double Pole Double Throw) configuration, rated for 0.4VA at 28V AC/DC. This through-hole mounted switch features a snap-on paddle actuator and is designed for applications requiring reliable switching in the 28V range. The part is currently active in production with 696 units in stock. Substitute parts become necessary when the primary part is unavailable, when design requirements allow for lower voltage ratings, or when alternative actuator geometries are acceptable for the application.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the B22KP-AG is determined by the following critical parameters:

Mandatory Matching Parameters:

• Circuit configuration: DPDT
• Switch function: On-On
• Current rating: 0.4VA (AC/DC)
• Mounting type: Through Hole
• Termination style: PC Pin
• Operating temperature range: -30°C to 85°C

Allowable Variation Parameters:

• Voltage rating: Substitute parts rated at 20V AC/DC are acceptable for applications where the system voltage does not exceed 20V
• Actuator type and length: Variations in actuator geometry are acceptable provided mechanical clearance and panel cutout compatibility are verified
• Electrical life: Substitute parts with different cycle ratings are acceptable based on application duty cycle requirements
• Compliance certifications: RoHS status and REACH compliance may differ; selection depends on end-product regulatory requirements

The two substitute parts listed (200MDP1T2B2M2RE and TT21NGPC1) meet all mandatory parameters but operate at reduced voltage ratings of 20V.

Parameter Comparison

Engineering Selection Recommendations

B22KP-AG (Primary Part): Select this part for applications requiring 28V operation. The part is active in production, ROHS3 compliant, and offers 50,000 electrical cycles. The snap-on paddle actuator provides distinct tactile feedback suitable for operator-intensive applications.

200MDP1T2B2M2RE (E-Switch Substitute): This part is suitable for 20V maximum system voltage applications. It is ROHS3 compliant and offers 1133 units in stock. The standard round actuator and shorter actuator length (5.33mm) require verification of panel cutout compatibility. Electrical life is rated at 30,000 cycles, suitable for moderate-duty applications.

TT21NGPC1 (TE Connectivity Substitute): This part is suitable for 20V maximum system voltage applications. It offers the highest electrical life rating at 80,000 cycles, making it appropriate for high-duty-cycle applications. However, this part is RoHS non-compliant and REACH status is vendor-undefined. Selection of this part requires confirmation that end-product regulatory requirements do not mandate RoHS compliance.

Frequently Asked Questions (FAQ)

Q: Can the B22KP-AG be replaced with a 20V-rated substitute in a 28V system? A: No. The substitute parts 200MDP1T2B2M2RE and TT21NGPC1 are rated for maximum 20V operation. Using them in a 28V system exceeds their voltage rating and will result in component failure or unsafe operation.

Q: What is the primary difference between the three parts? A: The B22KP-AG operates at 28V with a snap-on paddle actuator. The E-Switch and TE Connectivity substitutes operate at 20V with standard round actuators. All three share identical circuit configuration (DPDT), current rating (0.4VA), and mounting type (Through Hole).

Q: Are the actuator dimensions interchangeable? A: No. The B22KP-AG has a 9.40mm snap-on paddle actuator, while the substitutes have 5.33mm and 5.61mm standard round actuators. Panel cutout dimensions and mechanical clearance must be verified before substitution.

Q: Which substitute part has the longest operational life? A: The TT21NGPC1 is rated for 80,000 electrical cycles, compared to 50,000 cycles for the B22KP-AG and 30,000 cycles for the 200MDP1T2B2M2RE.

Q: Does RoHS compliance matter for my application? A: RoHS compliance is mandatory for products sold in the European Union and for many industrial and consumer applications. The B22KP-AG and 200MDP1T2B2M2RE are ROHS3 compliant. The TT21NGPC1 is RoHS non-compliant and should not be used in applications requiring RoHS certification.

Q: What inventory levels are available? A: B22KP-AG: 696 units; 200MDP1T2B2M2RE: 1133 units; TT21NGPC1: 1305 units.
