Phoenix Contact 2281652 Interface Module Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 2281652 is a 37-position interface module terminal block designed for D-Sub male connections with screw-type process-side termination. This component facilitates signal and power distribution between D-Sub connectors and field-level terminal block wiring, supporting 12-24 AWG conductors at 2.5 A per contact with 24VDC rated voltage.

The 2281652 carries an obsolete product status, making identification of functionally equivalent active alternatives essential for ongoing system maintenance, repair, and new design implementations. The substitute part 2322171 provides equivalent electrical and mechanical performance while maintaining active product availability.

Key Parameters

Substitute Part Grouping Explanation

Substitution between the Phoenix Contact 2281652 and 2322171 is valid based on the following critical parameters remaining identical across both parts:

• 37-position configuration with matching pin count and contact arrangement
• D-Sub male control-side connection with identical jackscrew socket cable retainer
• Screw-type terminal block process-side connection supporting 12-24 AWG wire gauge
• Electrical ratings: 2.5 A per contact, 24VDC rated voltage
• Operating temperature range: -20°C ~ 50°C
• Moisture sensitivity classification: MSL 1 (Unlimited)
• Regulatory compliance: Both RoHS compliant (2281652: RoHS; 2322171: ROHS3)

Dimensional differences (length and width) do not affect electrical or functional substitution capability, as both parts maintain the same connector interface geometry and mounting footprint compatibility with standard D-Sub and terminal block installations.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 2322171 is the direct functional equivalent for the obsolete 2281652. Selection of the 2322171 is supported by:

Product Status: The 2322171 maintains active product status, ensuring continued availability, technical support, and supply chain reliability. The 2281652 obsolete classification necessitates transition to an active equivalent for new procurements and long-term system support.

Regulatory Compliance: Both parts meet RoHS requirements. The 2322171 carries ROHS3 compliance, representing the current regulatory standard. Both parts are classified under identical ECCN (EAR99) and HTSUS (8536.90.4000) codes, confirming equivalent export and tariff treatment.

Electrical and Mechanical Equivalence: Identical electrical ratings (2.5 A per contact, 24VDC), connector configurations (37-position D-Sub male with jackscrew socket), and process-side termination (screw-type terminal blocks for 12-24 AWG) ensure direct functional substitution without circuit redesign or installation modification.

Environmental Classification: Both parts share MSL 1 (Unlimited) moisture sensitivity, indicating equivalent handling and storage requirements with no moisture-sensitive device precautions necessary.

Frequently Asked Questions (FAQ)

Q: Can the 2322171 directly replace the 2281652 in existing installations?

A: Yes. Both parts maintain identical electrical ratings (2.5 A per contact, 24VDC), 37-position configuration, D-Sub male connector interface with jackscrew socket, and screw-type terminal block termination for 12-24 AWG wire. No circuit modification or installation redesign is required.

Q: What is the significance of the product status difference between the two parts?

A: The 2281652 is classified as obsolete, indicating Phoenix Contact has discontinued production and support. The 2322171 is active, ensuring ongoing availability, technical documentation, and supply chain access. For new designs and system replacements, the 2322171 is the appropriate selection.

Q: Are there dimensional differences between these parts, and do they affect substitution?

A: The 2322171 has reduced length (2.862" versus 4.429") and width (2.717" versus 3.031") compared to the 2281652. These dimensional differences do not affect electrical substitution or connector interface compatibility. Physical space constraints in specific installations should be evaluated independently.

Q: Do both parts meet current regulatory requirements?

A: Yes. Both parts are RoHS compliant. The 2322171 carries ROHS3 certification, representing the current regulatory standard. Both share identical ECCN (EAR99) and HTSUS (8536.90.4000) classifications for export and tariff purposes.

Q: What is the difference between the FLKM and VIP series designations?

A: Both designations indicate VARIOFACE family membership within Phoenix Contact's terminal block product line. The series variation reflects internal product line organization and does not affect electrical or mechanical substitution capability.

Q: Are there any packaging differences between the two parts?

A: The 2281652 packaging is listed as unspecified, while the 2322171 is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact functional equivalence or performance.
