Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the PLC-BPT-5DC/1/ACT is determined by the following critical parameters:

• Mounting Type: DIN Rail (required match)
• Termination Style: Spring Terminal (required match)
• Application Compatibility: Miniature Relays (required match)
• Manufacturer: Phoenix Contact (preferred for series continuity)
• RoHS Compliance: Required for regulatory alignment

The Phoenix Contact 2900443 qualifies as a substitute based on matching mounting type, termination style, and application compatibility. While the substitute belongs to the PLC-BPIT series rather than PLC-BPT, both are Phoenix Contact relay socket products designed for identical mounting and termination configurations.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2900443 (PLC-BPIT series) is the designated substitute for the obsolete PLC-BPT-5DC/1/ACT. Selection is based on:

• Identical DIN rail mounting configuration
• Matching spring terminal termination
• Equivalent miniature relay application compatibility
• Active product status ensuring ongoing availability
• ROHS3 compliance exceeding the original RoHS requirement
• Unlimited moisture sensitivity rating matching the original specification

The transition from PLC-BPT to PLC-BPIT series represents a product line evolution within Phoenix Contact's relay socket portfolio, with maintained functional and mechanical compatibility for DIN rail-mounted miniature relay applications.

Frequently Asked Questions (FAQ)

Q: Can the 2900443 directly replace the 2900448 in existing installations?

A: Yes. Both components share identical mounting type (DIN rail), termination style (spring terminal), and application compatibility (miniature relays). The series designation change reflects product line evolution rather than functional modification.

Q: What is the significance of the ROHS3 compliance on the substitute part?

A: ROHS3 compliance represents an updated regulatory standard that supersedes the original RoHS requirement. This enhancement ensures the substitute meets current environmental and material restriction directives.

Q: Are there any packaging differences between the main part and substitute?

A: Both parts are supplied in bulk packaging, ensuring consistent handling and storage requirements.

Q: Why is the original part classified as obsolete?

A: Product obsolescence typically reflects manufacturer discontinuation decisions. The availability of the functionally equivalent 2900443 provides continuity for applications requiring DIN rail-mounted relay sockets with spring terminal termination.
