Key Parameters

Substitute Part Grouping Explanation

The 34BWSP12B4M7RT qualifies as an equivalent substitute for the 34DWMSP15B4M7RT based on the following critical parameters:

Matching Parameters:

• Identical circuit configuration (SPDT)
• Identical switch function (On-On)
• Identical current rating (0.4VA AC/DC)
• Identical voltage ratings (20V AC and 20V DC)
• Identical mounting type (Through Hole, Right Angle, Vertical)
• Identical termination style (PC Pin)
• Identical ingress protection rating (IP67)
• Identical operating temperature range (-30°C to 85°C)
• Identical actuator material (Brass, Chrome Plated)
• Identical RoHS compliance status (ROHS3 Compliant)

Differing Parameters:

• Actuator length: 34DWMSP15B4M7RT has 10.70mm; 34BWSP12B4M7RT has 7.60mm
• Electrical life: 34DWMSP15B4M7RT rated for 30,000 cycles; 34BWSP12B4M7RT rated for 50,000 cycles
• Series designation: 34D versus 34B

These differences do not affect electrical compatibility or functional equivalence in applications where the shorter actuator length and extended cycle life are acceptable or beneficial.

Parameter Comparison

Engineering Selection Recommendations

Both the 34DWMSP15B4M7RT and 34BWSP12B4M7RT are active production parts with full ROHS3 compliance and REACH unaffected status, making them suitable for current design implementations. The 34BWSP12B4M7RT offers extended electrical life (50,000 cycles versus 30,000 cycles), which may provide longer service intervals in high-cycle applications. The reduced actuator length (7.60mm versus 10.70mm) of the 34BWSP12B4M7RT requires panel cutout verification to ensure mechanical fit within the intended enclosure. Both parts maintain identical electrical specifications and environmental protection ratings, ensuring functional equivalence in circuit applications.

Frequently Asked Questions (FAQ)

Q: Are the 34DWMSP15B4M7RT and 34BWSP12B4M7RT electrically interchangeable?

A: Yes. Both parts share identical electrical specifications: SPDT circuit configuration, 0.4VA current rating, 20V AC/DC voltage ratings, and On-On switch function. They are electrically equivalent for all circuit applications within these parameters.

Q: What is the primary difference between these two parts?

A: The main differences are actuator length (10.70mm versus 7.60mm) and electrical life rating (30,000 cycles versus 50,000 cycles). The 34BWSP12B4M7RT has a shorter actuator and higher cycle rating.

Q: Does the shorter actuator length of the 34BWSP12B4M7RT affect compatibility?

A: Actuator length affects panel cutout and mechanical fit within the enclosure. The 7.60mm actuator of the 34BWSP12B4M7RT requires verification against panel thickness and available space. Electrical and functional compatibility remain unchanged.

Q: Which part should be selected for high-cycle applications?

A: The 34BWSP12B4M7RT is rated for 50,000 electrical cycles compared to 30,000 cycles for the 34DWMSP15B4M7RT, making it suitable for applications requiring extended operational life.

Q: Are both parts RoHS compliant?

A: Yes. Both the 34DWMSP15B4M7RT and 34BWSP12B4M7RT are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: What is the operating temperature range for both parts?

A: Both parts operate across the identical temperature range of -30°C to 85°C, ensuring thermal compatibility in equivalent applications.

Q: Do both parts feature the same ingress protection rating?

A: Yes. Both parts are rated IP67 (Dust Tight, Waterproof) with epoxy sealed terminals, providing identical environmental protection.
