Key Parameters

Substitute Part Grouping Explanation

Substitute compatibility for the Phoenix Contact 3244070 is determined by the following critical parameters:

• Position and Level Configuration: 2 positions, 1 level (fixed requirement)
• Terminal Width: 5.2mm (mechanical fit requirement)
• Mounting Type: Direct Mount (PCB interface requirement)
• Electrical Ratings: Minimum 24 A (IEC) and 800 V (IEC) to maintain performance envelope
• Wire Gauge Compatibility: Overlap within 12-28 AWG range
• Housing Color: Blue (visual and assembly identification)
• Insulation Material: Polyamide (PA), Nylon with UL94 V-0 rating (safety and thermal requirements)

The Phoenix Contact 3249006 qualifies as a substitute part because it maintains all critical parameters within acceptable tolerances, despite originating from the CLIPLINE MPT series and featuring Push In/Spring termination instead of pure spring cage design.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 3249006 serves as a direct substitute for the 3244070 based on the following engineering criteria:

Electrical Compatibility: Both parts maintain identical IEC current (24 A) and voltage (800 V) ratings. The 3249006 provides enhanced UL voltage rating (800 V vs. 600 V), representing a performance improvement rather than compromise.

Mechanical Compatibility: Terminal width (5.2mm), position count (2), level configuration (1), and direct mount interface are identical, ensuring PCB footprint and assembly compatibility.

Material and Safety Compliance: Both components utilize Polyamide (PA) nylon insulation with UL94 V-0 flammability rating and maintain ROHS3 compliance, satisfying regulatory and thermal requirements.

Wire Gauge Consideration: The 3249006 supports 12-26 AWG (0.14-4mm²), which is narrower than the 3244070 range (12-28 AWG / 0.08-4mm²). Applications using 28 AWG or wire cross-sections below 0.14mm² require verification against actual circuit requirements.

Product Status Advantage: The 3249006 maintains Active product status, ensuring long-term availability and supply chain stability compared to the Last Time Buy status of the 3244070.

Frequently Asked Questions (FAQ)

Q: Can the 3249006 directly replace the 3244070 in existing designs?

A: Yes, for applications within the 12-26 AWG wire gauge range. The 3249006 matches all critical mechanical and electrical parameters. If your design uses 28 AWG wire or smaller cross-sections (below 0.14mm²), component-level testing is required to confirm compatibility with the narrower wire gauge range.

Q: What is the difference between Spring Cage and Push In/Spring termination?

A: The 3244070 uses pure spring cage termination, while the 3249006 combines push-in and spring mechanisms. Both provide secure wire retention and are compatible with direct mount PCB applications. The termination style difference does not affect electrical performance or mechanical fit.

Q: Are there any compliance or certification differences?

A: Both components maintain identical UL94 V-0 flammability ratings, ROHS3 compliance, and equivalent electrical certifications. The 3249006 provides superior UL voltage rating (800 V vs. 600 V), representing no compromise in regulatory standing.

Q: Why is the 3244070 classified as Last Time Buy?

A: Last Time Buy status indicates Phoenix Contact has discontinued production of the CLIPLINE MSB series 3244070. The 3249006 from the active CLIPLINE MPT series provides functional equivalence with ongoing availability.

Q: What should I verify before implementing the 3249006 as a substitute?

A: Confirm that your application wire gauges fall within 12-26 AWG (0.14-4mm²). Verify that the Push In/Spring termination mechanism is compatible with your assembly process. Both components share identical electrical ratings and mechanical interfaces, eliminating additional validation requirements for standard applications.
