Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the 1825143-1 are grouped based on strict electrical and mechanical compatibility criteria. The primary substitution logic is determined by the following parameters:

Critical Matching Parameters:

• Circuit Configuration: DPDT (all substitutes match)
• Switch Function: On-On (all substitutes match)
• Mounting Type: Through Hole, Right Angle (all substitutes match)
• Termination Style: PC Pin (all substitutes match)
• Operating Temperature Range: -30°C ~ 85°C (all substitutes match)
• Current Rating: 0.4VA AC/DC (exact match required for direct substitution)
• Voltage Rating: 20V AC/DC (exact match required for direct substitution)

Substitution Categories:

Category 1: Direct Electrical Equivalents (0.4VA @ 20V) Parts that maintain identical electrical ratings and are suitable for direct replacement in applications with the same voltage and current requirements:

• 7201P4D9ABE (C&K)
• E201MD1AV2BE (C&K)

Category 2: Higher-Rated Alternatives (5A @ 120V AC / 28V DC) Parts with elevated electrical ratings that provide design margin and extended electrical life for applications where higher performance is acceptable:

• 100DP1T2B4M6QE (E-Switch)
• 7201MD9AQE (C&K)

Parameter Comparison

Engineering Selection Recommendations

For Direct Electrical Replacement (0.4VA @ 20V Applications):

The C&K 7201P4D9ABE and C&K E201MD1AV2BE are direct electrical equivalents to the 1825143-1. Both parts maintain identical voltage and current ratings, DPDT configuration, and On-On switching function. Selection between these two depends on mechanical requirements:

• 7201P4D9ABE: Features a flat anti-rotation actuator and extended electrical life (100,000 cycles). Suitable for applications requiring enhanced durability and actuator stability. Actuator length of 8.13mm differs from the main part.

• E201MD1AV2BE: Matches the standard round actuator type and actuator length (7.62mm) of the main part. Offers vertical mounting orientation option. Electrical life rated at 40,000 cycles. Ingress protection rated IP57, which is lower than the main part's IP67 rating.

All direct equivalents are ROHS3 compliant and active in production status.

For Higher-Performance Applications (5A @ 120V AC / 28V DC):

The E-Switch 100DP1T2B4M6QE and C&K 7201MD9AQE provide elevated electrical ratings suitable for applications where higher current capacity and voltage margin are required. These parts are not direct replacements but are compatible with the same circuit topology and mounting configuration:

• 100DP1T2B4M6QE: Rated 5A at 120V AC and 28V DC. Electrical life of 40,000 cycles. Shortest actuator length at 5.08mm. Packaged in bulk format.

• 7201MD9AQE: Rated 5A at 120V AC and 28V DC. Highest electrical life rating at 100,000 cycles. Actuator length of 6.86mm. Packaged in tray format.

Both higher-rated alternatives are ROHS3 compliant and active in production. Use of these parts in applications originally specified for 0.4VA @ 20V operation is acceptable from an electrical standpoint but requires verification of mechanical fit and panel cutout compatibility.

Frequently Asked Questions (FAQ)

Q: Can the 7201P4D9ABE be used as a direct replacement for the 1825143-1?

A: The 7201P4D9ABE is electrically equivalent with matching 0.4VA @ 20V ratings and DPDT On-On configuration. However, the actuator type differs (flat anti-rotation versus standard round) and actuator length is 8.13mm compared to 7.62mm. Mechanical fit and panel cutout compatibility must be verified before substitution.

Q: What is the difference between the E201MD1AV2BE and the main part 1825143-1?

A: Both parts share identical electrical ratings (0.4VA @ 20V), circuit configuration (DPDT On-On), and actuator length (7.62mm). The E201MD1AV2BE offers a vertical mounting orientation option and is rated IP57 for ingress protection, compared to the main part's IP67 rating. Electrical life is 40,000 cycles versus 6,000 cycles for the main part.

Q: When should I use the higher-rated 5A @ 120V alternatives?

A: The 100DP1T2B4M6QE and 7201MD9AQE are suitable for applications where the circuit can accommodate higher voltage and current ratings. These parts provide extended electrical life (40,000 to 100,000 cycles) and design margin. Use is appropriate when panel space and mechanical constraints allow for the different actuator lengths (5.08mm and 6.86mm respectively).

Q: Are all substitute parts ROHS3 compliant?

A: Yes. The main part 1825143-1 and all four substitute parts (7201P4D9ABE, E201MD1AV2BE, 100DP1T2B4M6QE, and 7201MD9AQE) are ROHS3 compliant.

Q: What is the difference in ingress protection between the main part and substitutes?

A: The main part 1825143-1 is rated IP67 (dust tight, waterproof). The E201MD1AV2BE is rated IP57 (dust protected, waterproof). The 100DP1T2B4M6QE and 7201MD9AQE do not specify ingress protection ratings. For applications requiring IP67 protection, the main part or E201MD1AV2BE (with lower IP57 rating) should be evaluated against specific environmental requirements.

Q: How do actuator lengths affect substitution?

A: Actuator length determines panel clearance and mechanical fit. The main part has a 7.62mm actuator. Substitutes range from 5.08mm (100DP1T2B4M6QE) to 8.13mm (7201P4D9ABE). Shorter actuators provide more panel clearance; longer actuators may require panel cutout adjustment. Verify mechanical compatibility with the application's panel thickness and cutout dimensions before substitution.

Q: What is the electrical life difference between the main part and substitutes?

A: The main part 1825143-1 is rated for 6,000 electrical cycles. Direct equivalents offer higher cycle ratings: 7201P4D9ABE (100,000 cycles) and E201MD1AV2BE (40,000 cycles). Higher-rated alternatives provide 40,000 to 100,000 cycles. Extended electrical life indicates longer operational durability in high-cycle applications.

Q: Are there packaging differences between substitute parts?

A: Yes. The main part 1825143-1 is packaged in standard format. The 7201P4D9ABE, E201MD1AV2BE, and 7201MD9AQE are packaged in trays. The 100DP1T2B4M6QE is packaged in bulk. Packaging format affects order quantities and handling but does not impact electrical or mechanical performance.
