Phoenix Contact 3249208 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 3249208 is a 4-position terminal block from the CLIPLINE ST series, designed for direct mount applications with push-in spring termination. This component is classified as Last Time Buy, indicating discontinued production status. The part operates at IEC ratings of 24 A and 800 V, with UL ratings of 20 A and 300 V, accommodating wire gauges from 12-28 AWG (0.08-4 mm²). Finding equivalent or substitute parts is necessary due to the Last Time Buy status, which restricts future availability and may impact long-term supply chain planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 3249208 is based on the following critical parameters that must align for functional equivalence:

Mandatory Matching Parameters:

• Number of Positions: 4
• Number of Levels: 1
• Type: Middle
• Termination Style: Push In, Spring
• Mounting Type: Direct Mount
• Housing Color: Blue
• Material - Insulation: Polyamide (PA), Nylon
• Material Flammability Rating: UL94 V-0

Allowable Variation Parameters:

• Terminal Width: 10.3-10.4 mm (minor dimensional tolerance)
• Current - IEC: 24 A (minimum requirement)
• Voltage - IEC: 800 V (minimum requirement)
• Current - UL: 20 A (minimum requirement)
• Voltage - UL: 300 V or higher
• Wire Gauge - AWG: 12-26 AWG or broader range
• Wire Gauge - mm²: 0.08-4 mm² or broader range
• Length and Height: Dimensional variations acceptable within mechanical constraints

The Phoenix Contact 1429430 qualifies as a substitute part based on these criteria.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1429430 is a qualified substitute for the 3249208 based on electrical and functional equivalence. The substitute part maintains identical electrical ratings (24 A IEC, 800 V IEC, 20 A UL) and termination characteristics (push-in spring). Both parts share the same insulation material (Polyamide/Nylon) and flammability rating (UL94 V-0), ensuring compliance with safety standards.

The primary consideration for selection is wire gauge compatibility. The 3249208 accommodates 12-28 AWG (0.08-4 mm²), while the 1429430 supports 12-26 AWG (0.14-4 mm²). Applications requiring 28 AWG or 0.08 mm² wire connections must retain the original 3249208 part. For applications within the 12-26 AWG range, the 1429430 provides equivalent functionality with the advantage of active production status.

Dimensional differences exist: the 1429430 is shorter (27.30 mm vs. 32.00 mm length) and taller (36.00 mm vs. 22.00 mm height). Mechanical fit within the enclosure or mounting structure must be verified before substitution.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1429430 directly replace the 3249208 in all applications?

A: The 1429430 is electrically equivalent for applications using wire gauges 12-26 AWG. Applications requiring 28 AWG or 0.08 mm² wire connections require the original 3249208. Mechanical fit must be verified due to dimensional differences.

Q: What is the significance of the Last Time Buy status on the 3249208?

A: Last Time Buy indicates the manufacturer has discontinued production. Existing inventory is available, but future procurement will not be possible. The 1429430 is recommended for new designs or long-term supply chain continuity.

Q: Are there differences in the series designation between these parts?

A: Yes. The 3249208 belongs to the CLIPLINE ST series, while the 1429430 is part of the CLIPLINE MPTD series. Both are Phoenix Contact products with compatible electrical and functional characteristics.

Q: What wire gauge limitation exists with the 1429430?

A: The 1429430 supports 12-26 AWG (0.14-4 mm²), whereas the 3249208 supports 12-28 AWG (0.08-4 mm²). The substitute does not accommodate 28 AWG or 0.08 mm² conductors.

Q: How do the physical dimensions differ?

A: The 1429430 is 4.7 mm shorter in length (27.30 mm vs. 32.00 mm) and 14.00 mm taller in height (36.00 mm vs. 22.00 mm). Verify mechanical clearance and mounting compatibility in your application.

Q: Is the 1429430 RoHS compliant?

A: RoHS compliance status for the 1429430 is not specified in the available technical data. Verify compliance requirements with the manufacturer or distributor if RoHS certification is mandatory for your application.

Q: What is the voltage rating difference between the two parts?

A: Both parts meet the IEC standard at 800 V. Under UL standards, the 3249208 is rated 300 V, while the 1429430 is rated 800 V. The substitute exceeds the original part's UL voltage requirement.
