Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1940910 is determined by strict alignment of the following critical parameters:

• Position Count & Pitch: 4 positions at 0.200" (5.08mm) spacing
• Connector Type & Shrouding: Header with male pins, shrouded on all four sides
• Mounting Configuration: Vertical through-hole solder termination
• Electrical Ratings: Minimum 12A (IEC) at 400V (IEC); minimum 10A (UL) at 300V (UL)
• Compliance Standards: UL94 V-0 flammability rating and RoHS compliance

The Phoenix Contact 1955659 meets all substitution criteria. It maintains identical position count, pitch, connector type, shrouding configuration, and mounting orientation. Electrical ratings remain compatible: 12A per position (IEC) at 400V (IEC) and 10A (UL) at 300V (UL). Both parts carry UL94 V-0 and RoHS compliance certifications. The 1955659 is classified as active product status, ensuring ongoing availability and support.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1955659 is the qualified substitute for the obsolete 1940910 terminal block header. Both parts maintain identical mechanical and electrical specifications across all critical parameters: 4-position configuration, 5.08mm pitch, vertical through-hole solder mounting, and shrouded male pin design.

Electrical compatibility is confirmed: the 1955659 delivers 12A per position at 400V (IEC) and 10A at 300V (UL), meeting or exceeding the original part's performance envelope. Both components carry UL94 V-0 flammability certification and full RoHS compliance, ensuring regulatory alignment for applications requiring these standards.

The primary advantage of the 1955659 is its active product status, guaranteeing long-term availability and manufacturing support. This substitution eliminates obsolescence risk while maintaining full functional and electrical equivalence for new designs and production continuity.

Frequently Asked Questions (FAQ)

Q: Can the 1955659 be used as a direct replacement for the 1940910 in existing designs?

A: Yes. The 1955659 maintains identical position count, pitch, connector type, shrouding configuration, and mounting orientation. Electrical ratings are compatible across both IEC and UL standards. PCB footprints and mating connector compatibility remain unchanged.

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

A: The 1940910 uses polyamide (PA) nylon housing, while the 1955659 uses liquid crystal polymer (LCP). Both materials meet UL94 V-0 flammability requirements. LCP offers enhanced dimensional stability and chemical resistance in high-temperature or chemically aggressive environments.

Q: Are there differences in insulation height between the two parts?

A: The 1940910 has an insulation height of 0.480" (12.20mm), while the 1955659 measures 0.472" (12.00mm). This 0.008" (0.20mm) difference is within standard manufacturing tolerances and does not affect mechanical or electrical compatibility in standard applications.

Q: Does the 1955659 have a contact tail length specification?

A: Yes. The 1955659 specifies a contact tail length of 0.102" (2.60mm). This parameter is not provided for the 1940910 but does not affect substitution eligibility for through-hole solder termination applications.

Q: What is the packaging difference between these parts?

A: The 1940910 is listed with no specified packaging designation, while the 1955659 is supplied in bulk packaging. This distinction affects procurement and inventory management but does not impact electrical or mechanical performance.

Q: Are both parts RoHS compliant?

A: Yes. Both the 1940910 and 1955659 are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity ratings, suitable for standard storage and handling conditions without special precautions.
