Substitute Part Grouping Explanation

Substitute parts for the 736W-B/102 are identified based on strict electrical and mechanical parameter matching within the Qualtek 736W series. The substitution criteria are:

• Identical current rating: 15A
• Identical voltage rating: 125VAC
• Identical breaker type: Thermal
• Identical number of poles: 1
• Identical actuator type: Rocker
• Identical mounting type: Panel Mount
• Compliance with ROHS3 and REACH requirements

Parts meeting all these parameters are functionally equivalent and may be used as direct replacements in applications originally specified for the 736W-B/102.

Frequently Asked Questions (FAQ)

Q: Can the 736W-B/302 be used as a direct replacement for the 736W-B/102?

A: Yes. Both parts share identical electrical ratings (15A, 125VAC), breaker type (thermal), pole configuration (1-pole), actuator type (rocker), and mounting type (panel mount). The 736W-B/302 is the manufacturer-recommended substitute.

Q: What is the difference between the 736W-B/102 and 736W-B/302?

A: The primary difference is product status. The 736W-B/102 is obsolete, while the 736W-B/302 is active. All functional and electrical parameters are identical.

Q: Are there any compliance differences between these parts?

A: No. Both parts are ROHS3 compliant and REACH unaffected, meeting identical regulatory standards.

Q: Will the 736W-B/302 fit in the same panel mount location as the 736W-B/102?

A: Yes. Both parts have identical mounting type specifications (panel mount) and belong to the same 736W series, ensuring mechanical compatibility.

Q: Why is the 736W-B/102 obsolete?

A: Product obsolescence is determined by the manufacturer. The 736W-B/302 is the active replacement within the same series.
