Phoenix Contact 1924211 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1924211 is a 4-position terminal block header with male pins, designed for vertical through-hole mounting with 5.00mm pitch spacing. This component is part of the COMBICON MSTBVA series and is actively manufactured. Terminal block headers serve as connection interfaces in industrial control systems, power distribution, and signal routing applications. Finding equivalent substitute parts is necessary to ensure supply chain flexibility, manage inventory across multiple suppliers, and maintain design compatibility when the primary part becomes unavailable.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1924211 is determined by the following critical parameters:

• Electrical Compatibility: Current and voltage ratings must meet or exceed the application requirements. The main part specifies 16A at 630V (IEC) and 16A at 300V (UL). Substitute parts must maintain these electrical specifications or higher.
• Physical Compatibility: Number of positions (4), pitch spacing (5.00mm), header orientation (vertical), and mounting type (through hole) must be identical to ensure PCB footprint compatibility.
• Termination Method: Solder termination is required for direct replacement.
• Shrouding Configuration: 4-side shrouded design must be maintained for mechanical and electrical safety.
• Material and Compliance: Housing material, flammability rating (UL94 V-0), and RoHS3 compliance ensure regulatory and environmental compatibility.

The TE Connectivity AMP Connectors part 796642-4 qualifies as a substitute based on matching these core parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the Phoenix Contact 1924211 and TE Connectivity 796642-4 are active products with ROHS3 compliance and UL94 V-0 flammability ratings, ensuring regulatory alignment for industrial applications.

The TE Connectivity 796642-4 is electrically and mechanically compatible with the Phoenix Contact 1924211 for applications requiring up to 15A at 300V. The 1A difference in UL current rating should be evaluated against specific application requirements. The contact tail length difference of 0.4mm (TE part shorter) is within typical PCB design tolerances for through-hole solder joints but should be verified during board layout review.

Both parts share identical pitch, position count, orientation, and shrouding configuration, ensuring direct PCB footprint compatibility. Material composition differences (PA vs. PA66 nylon variants) are within the same polymer family and maintain equivalent flammability and environmental performance.

Frequently Asked Questions (FAQ)

Q: Can the TE Connectivity 796642-4 be used as a direct replacement for the Phoenix Contact 1924211?

A: Yes, for applications requiring up to 15A at 300V. Both parts have identical pitch (5.00mm), position count (4), orientation (vertical), and shrouding (4-side). Verify that your application does not exceed the TE part's 15A current rating.

Q: What is the significance of the contact tail length difference?

A: The Phoenix Contact part has a 0.154" (3.90mm) tail length, while the TE part has 0.138" (4.60mm). This 0.4mm difference affects solder joint depth on the PCB. Confirm that your board design accommodates the shorter tail length, particularly if minimum solder fillet specifications are critical.

Q: Are the housing materials equivalent?

A: Both use polyamide nylon materials with UL94 V-0 flammability ratings. The Phoenix Contact uses PA nylon, while TE uses PA66 (nylon 6/6). Both materials provide equivalent electrical insulation, mechanical strength, and environmental performance for this application category.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the Phoenix Contact 1924211 and TE Connectivity 796642-4 are ROHS3 compliant and carry UL94 V-0 flammability certification, meeting industrial regulatory requirements.

Q: What inventory considerations should be evaluated?

A: The Phoenix Contact 1924211 has 1,175 pieces in stock, while the TE Connectivity 796642-4 has 42,571 pieces available. The TE part offers significantly higher inventory availability for supply chain continuity.
