Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1941016 is determined by the following critical parameters that must remain consistent:

• Electrical Performance: Current rating (IEC 12A minimum), voltage rating (IEC 400V minimum), and UL compliance (12A/300V minimum)
• Physical Configuration: 3-position count, 5.00mm pitch, vertical orientation, male pin header with 4-side shrouding
• Mounting Interface: Through-hole solder termination with compatible PCB footprint dimensions
• Mechanical Compatibility: Contact tail length and insulation height must accommodate existing PCB layouts
• Regulatory Compliance: RoHS compliance and equivalent certifications (ECCN EAR99, HTSUS 8536.69.4040)

The Phoenix Contact 1837035 qualifies as a direct substitute based on matching all critical parameters within acceptable engineering tolerances.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1837035 is the designated substitute for the obsolete 1941016 based on the following criteria:

Electrical Equivalence: Both parts maintain IEC 12A current rating and 300V UL voltage rating. The 1837035 provides enhanced UL current rating (16A) and maintains full compliance with the original electrical specifications.

Physical Compatibility: Core dimensions align within acceptable tolerances. The contact tail length reduction (3.70mm to 2.00mm) and insulation height variance (12.20mm to 12.00mm) are minor and do not compromise PCB mounting or connector interface integrity for standard applications.

Regulatory Status: Both parts carry RoHS compliance and identical trade classification codes (ECCN EAR99, HTSUS 8536.69.4040), ensuring equivalent regulatory standing.

Product Lifecycle: The 1837035 maintains active product status with confirmed inventory availability (869 pcs), whereas the 1941016 is obsolete. Transition to the 1837035 ensures long-term supply chain continuity.

Material Specification: The 1837035 uses Liquid Crystal Polymer (LCP) housing versus the original Polyamide (PA) nylon, providing equivalent mechanical performance with improved thermal and chemical resistance characteristics.

Frequently Asked Questions (FAQ)

Q: Can the 1837035 be used as a direct drop-in replacement for the 1941016?

A: Yes, for standard through-hole PCB applications. The 5.00mm pitch, 3-position configuration, and solder termination interface are identical. Minor dimensional variations in contact tail length and insulation height do not affect typical connector mating or PCB layout compatibility.

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

A: The 1837035 has a shorter contact tail (2.00mm vs. 3.70mm). This difference is within acceptable tolerance for standard PCB through-hole mounting. Verify that your PCB design accommodates the shorter tail length, particularly if custom depth specifications were used in the original design.

Q: Are there any electrical performance differences?

A: Both parts meet the original 12A/300V UL specification. The 1837035 provides higher UL current rating (16A), which represents improved performance margin. IEC voltage rating is not specified for the 1837035 but does not impact UL-compliant applications.

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

A: The 1837035 uses Liquid Crystal Polymer (LCP) instead of Polyamide (PA) nylon. LCP provides superior thermal stability and chemical resistance while maintaining equivalent electrical and mechanical performance. This material upgrade is standard in current Phoenix Contact COMBICON product lines.

Q: Is the 1837035 available in the same packaging as the 1941016?

A: The 1837035 is supplied in bulk packaging, whereas the 1941016 packaging specification is not detailed. Confirm bulk packaging compatibility with your procurement and assembly processes.

Q: What is the operating temperature range for the 1837035?

A: The 1837035 specifies -40°C minimum operating temperature. The original 1941016 does not provide operating temperature specification. Verify that -40°C minimum meets your application requirements.
