Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 5443289 is determined by strict alignment of the following critical parameters:

• Position Count & Configuration: 20 positions arranged as 10 per level across 2 levels
• Pitch Spacing: 0.197" (5.00mm) center-to-center distance
• Header Type & Orientation: Male pins, shrouded on four sides, 90° right-angle configuration
• Termination & Mounting: Solder termination with through-hole mounting
• Electrical Ratings: Minimum 10A at 400V (IEC) or 12A at 300V (UL)
• Physical Dimensions: Contact tail length 0.126" (3.20mm) and insulation height 0.933" (23.70mm)
• Compliance: UL94 V-0 flammability rating and RoHS compliance

The substitute part Phoenix Contact 1846593 meets all these criteria and is classified as active, providing a direct functional replacement for the obsolete 5443289.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1846593 is the appropriate substitute for the obsolete 5443289. Both components share identical electrical ratings under IEC standards (10A at 400V), matching mechanical dimensions, and equivalent compliance certifications. The 1846593 offers enhanced UL current rating (15A versus 12A), representing an improvement in electrical capacity while maintaining full backward compatibility in form factor and mounting interface.

The transition from the BCDH series to the COMBICON MDSTBA series reflects Phoenix Contact's product line evolution. The housing material change from polyamide to polybutylene terephthalate (PBT) provides enhanced thermal and chemical resistance characteristics while maintaining the UL94 V-0 flammability classification.

Frequently Asked Questions (FAQ)

Q: Can the 1846593 be used as a direct replacement for the 5443289 in existing designs?

A: Yes. Both components maintain identical pitch spacing (5.00mm), position configuration (20 positions in 2×10 arrangement), physical dimensions (contact tail length and insulation height), and mounting interface (through-hole solder termination). The 90° right-angle orientation and four-sided shrouding are identical.

Q: What is the difference in electrical ratings between these parts?

A: Under IEC standards, both are rated 10A at 400V. Under UL standards, the 5443289 is rated 12A at 300V, while the 1846593 is rated 15A at 300V. This represents an increase in current capacity for the substitute part.

Q: Why does the housing material differ between the two parts?

A: The 5443289 uses polyamide (PA/nylon) housing, while the 1846593 uses polybutylene terephthalate (PBT). Both materials maintain UL94 V-0 flammability compliance. PBT offers improved thermal stability and chemical resistance, reflecting modern material standards in the COMBICON MDSTBA series.

Q: Are both parts RoHS compliant?

A: Yes. Both the 5443289 and 1846593 are RoHS compliant with MSL rating of 1 (unlimited moisture sensitivity level).

Q: What is the packaging difference?

A: The 5443289 is supplied in standard packaging, while the 1846593 is supplied in bulk packaging. This reflects the active production status of the substitute part.
