Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5439549 is determined by the following critical parameters:

• Connector Type & Configuration: 2-position terminal block plug with female sockets
• Pitch Specification: 0.197" (5.00mm) center-to-center spacing
• Wire Entry Angle: 270° free-hanging (in-line) orientation
• Electrical Ratings: Minimum 12A current capacity and voltage compatibility (IEC 630V or UL 300V)
• Wire Gauge Compatibility: Support for 12-30 AWG (0.2-2.5mm²) conductors
• Termination Method: Screw-based wire termination with M3 screw specification
• Compliance Standards: RoHS compliance and UL94 V-0 flammability rating

The substitute part Phoenix Contact 1937732 is identified as a terminal block plug from the same manufacturer. However, detailed electrical and mechanical parameters for this substitute are not fully specified in the available data, limiting direct parameter-to-parameter verification.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1937732 is classified as an active product, whereas the 5439549 is obsolete. Both parts maintain RoHS compliance and identical MSL ratings, supporting long-term reliability in controlled storage environments. The active status of part 1937732 provides assurance of continued manufacturing support and supply chain availability.

Selection between these parts should prioritize the active product (1937732) for new designs and long-term system deployments. For legacy system maintenance where the original 5439549 specification is critical, verification of mechanical and electrical compatibility with the substitute is necessary prior to implementation, given the incomplete parameter specification for part 1937732 in available documentation.

Frequently Asked Questions (FAQ)

Q: What makes Phoenix Contact 1937732 a suitable substitute for 5439549?

A: Both parts are Phoenix Contact terminal block plugs with RoHS compliance and identical MSL ratings. The 1937732 is an active product, ensuring ongoing availability and manufacturing support compared to the obsolete 5439549.

Q: Are the electrical ratings identical between these parts?

A: The electrical specifications for part 1937732 are not fully documented in the available data. Confirmation of current capacity (12A), voltage ratings (IEC 630V or UL 300V), and wire gauge compatibility (12-30 AWG / 0.2-2.5mm²) is required before substitution in applications with specific electrical requirements.

Q: Does the 1937732 maintain the same 5mm pitch and 270° wire entry configuration?

A: The pitch and wire entry angle specifications for part 1937732 are not provided in the available documentation. Physical compatibility verification is necessary to confirm these mechanical parameters match the original 5439549 specification.

Q: What is the significance of the obsolete status for the 5439549?

A: Obsolete status indicates the manufacturer has discontinued production. While existing inventory may be available, future supply cannot be guaranteed. The active status of 1937732 provides long-term supply chain security for ongoing applications.

Q: Are both parts suitable for the same packaging and storage conditions?

A: Yes. Both parts share MSL Level 1 (Unlimited) rating, indicating no moisture sensitivity restrictions and compatibility with standard storage and handling procedures.
