Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5437457 is determined by strict alignment of the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 4
• Positions Per Level: 2
• Number of Levels: 2
• Pitch: 0.200" (5.08mm)
• Header Orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Termination Style: Solder
• Mounting Type: Through Hole
• Contact Tail Length: 0.126" (3.20mm)
• Insulation Height: 0.933" (23.70mm)
• Contact Mating Finish: Tin
• Material Flammability Rating: UL94 V-0
• RoHS Status: RoHS Compliant

Acceptable Variation Parameters:

• Housing Material: Polyamide (PA), Nylon or Polybutylene Terephthalate (PBT)
• Current Rating: IEC 10A minimum; UL 12A minimum
• Voltage Rating: IEC 400V minimum; UL 300V minimum
• Color: Gray or Green
• Series designation: BCDH or COMBICON MDSTBA
• Product Status: Active preferred over Obsolete

The Phoenix Contact 1842063 meets all mandatory matching parameters and represents an active equivalent with enhanced current capacity (15A UL rating) and improved housing material (PBT).

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1842063 is the direct active equivalent for the obsolete 5437457. Both components share identical electrical specifications (IEC: 10A/400V; UL: 12A/300V minimum), mechanical dimensions, and flammability certification (UL94 V-0). The 1842063 provides enhanced UL current capacity (15A versus 12A) and uses PBT housing material instead of polyamide, offering improved thermal and chemical resistance. Both parts maintain RoHS compliance and MSL 1 rating. The transition from the BCDH series to the COMBICON MDSTBA series reflects Phoenix Contact's product line evolution. The 1842063 is currently in active production status, ensuring long-term availability and supply chain continuity.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1842063 directly replace the 5437457 in existing designs?

A: Yes. Both components share identical pitch (5.08mm), position count (4), orientation (90° right angle), termination method (solder), and mounting type (through hole). Electrical ratings meet or exceed the original specification. Physical footprint and pin configuration are identical.

Q: What is the difference in housing material between these parts?

A: The 5437457 uses polyamide (PA/nylon), while the 1842063 uses polybutylene terephthalate (PBT). Both materials meet UL94 V-0 flammability requirements. PBT offers superior thermal stability and chemical resistance.

Q: Are there any current or voltage rating differences?

A: IEC ratings are identical (10A/400V). UL ratings differ slightly: the 5437457 is rated 12A at 300V, while the 1842063 is rated 15A at 300V. The 1842063 provides higher current capacity.

Q: What packaging is available for the 1842063?

A: The 1842063 is supplied in bulk packaging, compared to the original part's unspecified packaging format.

Q: Are both parts RoHS compliant?

A: Yes. Both the 5437457 and 1842063 are RoHS compliant with MSL 1 (unlimited moisture sensitivity level).

Q: Why is the 5437457 listed as obsolete?

A: The 5437457 belongs to the BCDH series, which has been superseded by Phoenix Contact's COMBICON MDSTBA series. The 1842063 represents the current production equivalent within the updated product line.
