Weidmüller RS-OD /O40 CBL INTERFACE (990345) Equivalent & Substitute Parts

Part Overview

The Weidmüller 990345 is a 40-position, 2-row adapter terminal block designed to convert screw connection terminal blocks to rectangular connector male pins. This component interfaces between DIN rail-mounted terminal blocks and rectangular connectors using screw terminal connections with wire gauge compatibility of 14-26 AWG.

The 990345 is classified as obsolete. Identifying equivalent substitute parts is necessary to maintain system compatibility and ensure continued availability for applications requiring this specific adapter interface configuration.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Weidmüller 990345 is determined by the following critical parameters:

• Position Configuration: 40 positions, 2-row arrangement
• Adapter Interface: Screw connection terminal blocks converting to rectangular connector male pins
• Wire Gauge Compatibility: Acceptable range for screw terminal connection (14-26 AWG for main part; 12-24 AWG for substitute)
• Connector Type: Rectangular connector with male pins, 40 positions, 2 rows
• Electrical Specifications: Compliance certifications (RoHS, REACH, ECCN classification)

The Phoenix Contact 2280271 qualifies as a substitute based on matching position count, adapter interface type, connector configuration, and overlapping wire gauge range. Differences in mounting type (panel mount/feed through vs. DIN rail) and product status (active vs. obsolete) do not preclude functional substitution when mechanical integration is feasible.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2280271 is the identified substitute for the obsolete Weidmüller 990345. Both components share identical position configuration (40 positions, 2 rows), adapter interface type (screw connection to rectangular connector male pins), and regulatory classification (REACH Unaffected, EAR99).

The 2280271 is currently in active production status, ensuring ongoing availability. Wire gauge compatibility overlaps within the 12-24 AWG range, accommodating the original specification of 14-26 AWG. The primary mechanical difference is mounting type: the 2280271 uses panel mount and feed-through configuration compared to the DIN rail mounting of the original part. This difference requires evaluation based on the specific installation environment and mechanical constraints of the target application.

Both components maintain equivalent electrical compliance and connector interface specifications necessary for functional substitution.

Frequently Asked Questions (FAQ)

Q: What makes the Phoenix Contact 2280271 a suitable substitute for the Weidmüller 990345?

A: Both components provide identical 40-position, 2-row adapter interface converting screw connection terminal blocks to rectangular connector male pins. Position count, connector type, and electrical interface specifications are equivalent.

Q: Are there wire gauge compatibility concerns when substituting the 2280271 for the 990345?

A: The 990345 supports 14-26 AWG; the 2280271 supports 12-24 AWG. The overlap range of 14-24 AWG is compatible. Applications using wire gauges between 24-26 AWG require verification against the 2280271 specifications.

Q: How does the mounting type difference affect substitution?

A: The 990345 uses DIN rail mounting; the 2280271 uses panel mount and feed-through mounting. Mechanical integration depends on the installation configuration. DIN rail-specific applications may require mechanical adaptation or alternative mounting solutions.

Q: What is the inventory status for these components?

A: The Weidmüller 990345 (obsolete) has 898 pieces in stock. The Phoenix Contact 2280271 (active product) has 921 pieces in stock and represents the current production alternative.

Q: Are regulatory and compliance specifications equivalent?

A: Both components are REACH Unaffected and classified as EAR99. The 2280271 is ROHS3 Compliant; the 990345 has not applicable RoHS status. Compliance requirements for the target application determine if this difference is relevant.
