Substitute Part Grouping Explanation

Substitution of the 55100-3H-04-D with the 55100-3H-04-A is based on matching the following critical electrical and mechanical parameters:

• Hall effect sensor technology with voltage output
• South pole magnet actuator material
• 10 kHz operating frequency
• 2.7V to 24V supply voltage range
• -40°C to 100°C operating temperature range
• Module package configuration
• ROHS3 compliance and MSL Level 1 rating

The primary distinction between these parts is product status and termination style. The 55100-3H-04-D features wire leads with connector termination and is obsolete. The 55100-3H-04-A provides wire leads termination and maintains active product status, ensuring continued availability and manufacturer support.

Parameter Comparison

Engineering Selection Recommendations

The 55100-3H-04-A is the manufacturer-recommended substitute for the obsolete 55100-3H-04-D.

Frequently Asked Questions (FAQ)

Q: What is the primary difference between the 55100-3H-04-D and 55100-3H-04-A?

A: The 55100-3H-04-D is obsolete, while the 55100-3H-04-A maintains active product status. The termination style differs slightly: the -D variant includes connector termination, while the -A variant provides standard wire leads. Electrical performance and operating parameters are identical.

Q: Are the electrical specifications identical between these parts?

A: Yes. Both components operate at 2.7V to 24V supply voltage, 10 kHz frequency, and -40°C to 100°C temperature range with identical Hall effect voltage output characteristics and South pole magnet actuation.

Q: Does the termination style difference affect circuit compatibility?

A: Termination style differences require mechanical interface verification. The 55100-3H-04-A wire leads configuration must be compatible with your existing connector or soldering approach. Consult your circuit design documentation to confirm termination compatibility.

Q: Are both parts RoHS compliant?

A: Yes. Both the 55100-3H-04-D and 55100-3H-04-A are ROHS3 compliant with MSL Level 1 rating, meeting current environmental and manufacturing standards.

Q: Why should I transition from the obsolete part to the substitute?

A: The 55100-3H-04-D is obsolete and subject to discontinuation. The 55100-3H-04-A provides identical electrical functionality with active product status, ensuring long-term availability, manufacturer support, and supply chain reliability.
