SW248CD7 Toggle Switch DPDT Equivalent & Substitute Parts

Part Overview

The SW248CD7 is an APEM Inc. toggle switch featuring DPDT (Double Pole Double Throw) circuitry with On-Off-Mom switching function. Rated for 0.4VA at 20V AC/DC, this through-hole right-angle mounted component is designed for applications requiring sealed, non-illuminated switching control. The part is currently active in production with 702 units in stock.

Substitute parts become necessary when the primary part reaches end-of-life status, when supply constraints occur, or when design requirements allow for functionally equivalent alternatives that meet the same electrical and mechanical specifications.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the SW248CD7 is determined by strict equivalence across the following critical parameters:

• Circuit configuration must be DPDT
• Switch function must be On-Off-Mom
• Current rating must be 0.4VA (AC/DC)
• Voltage ratings must be 20V AC and 20V DC minimum
• Mounting type must be through hole, right angle
• Actuator type must be standard round
• Termination style must be PC Pin
• Operating temperature range must encompass -20°C to 85°C
• Illumination must be non-illuminated
• Bushing must be unthreaded

The identified substitute parts meet all these core electrical and mechanical requirements, enabling direct functional replacement in circuit designs.

Parameter Comparison

Engineering Selection Recommendations

SW248CD7 (APEM Inc.) — Primary selection for new designs. Active product status ensures long-term availability and supply continuity. ROHS3 compliant with REACH unaffected status. Suitable for applications requiring compliance with current environmental regulations.

7207MD9ABE (C&K) — Preferred substitute for active production environments. Active product status with highest inventory availability (2322 units). ROHS3 compliant and REACH affected. Actuator length of 6.86mm is the shortest among alternatives, which may be advantageous in space-constrained panel layouts. Electrical life rating of 40,000 cycles meets standard industrial requirements.

2-1825143-4 (TE Connectivity ALCOSWITCH) — Not recommended for new designs due to obsolete product status. Suitable only for legacy system maintenance where existing inventory exists. IP67 ingress protection rating provides enhanced environmental sealing compared to other alternatives. Electrical life of 6,000 cycles is significantly lower than other options.

Frequently Asked Questions (FAQ)

Q: Can the 7207MD9ABE replace the SW248CD7 directly?

A: Yes. Both parts share identical electrical specifications (DPDT, 0.4VA, 20V AC/DC, On-Off-Mom function) and mechanical mounting (through hole, right angle, PC pin termination). Actuator length differs by 0.64mm (7.50mm vs. 6.86mm), which is within typical panel tolerance ranges for standard round actuators.

Q: What is the difference between the substitute parts?

A: The primary differences are product status, electrical life ratings, and environmental protection. The 7207MD9ABE (C&K) is active production with 40,000 cycle life. The 2-1825143-4 (TE Connectivity) is obsolete with only 6,000 cycle life but offers IP67 ingress protection. The SW248CD7 (APEM) is active with 50,000 cycle life and sealed features.

Q: Are there packaging considerations when substituting?

A: Yes. The SW248CD7 ships in bulk packaging, the 7207MD9ABE in trays, and packaging information for the 2-1825143-4 is not specified. Verify packaging requirements with procurement to ensure compatibility with assembly line equipment and inventory management systems.

Q: Does the operating temperature range affect substitution?

A: The SW248CD7 operates from -20°C to 85°C. Both substitute parts extend the lower limit to -30°C, providing broader temperature coverage. If your application operates above -20°C, all three parts are functionally equivalent in this parameter.

Q: What compliance certifications should I verify?

A: The SW248CD7 and 7207MD9ABE are both ROHS3 compliant. The 2-1825143-4 has not applicable RoHS status due to obsolete status. For new designs, prioritize ROHS3 compliant parts. REACH status varies: SW248CD7 is unaffected, 7207MD9ABE is affected, and 2-1825143-4 is vendor undefined.
