Phoenix Contact 1915893 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1915893 is an 18-position terminal block header with male pins, shrouded on four sides, featuring 0.200" (5.08mm) pitch vertical through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system maintenance and new design implementations. The part operates at 12A (IEC) / 12A (UL) with voltage ratings of 320V (IEC) and 300V (UL), housed in green polybutylene terephthalate (PBT) material with UL94 V-0 flammability rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1915893 is determined by strict alignment with the following critical parameters:

• Position Count & Pitch: All substitutes must maintain 18 positions at 0.200" (5.08mm) pitch
• Connector Type & Orientation: Header configuration with male pins, shrouded (4 side), vertical through-hole mounting
• Electrical Ratings: Current capacity of 12A (IEC/UL) and voltage compatibility within specified ranges
• Mounting Compatibility: Through-hole PCB mounting with compatible contact tail length and insulation height
• Regulatory Compliance: UL94 V-0 flammability rating and RoHS compliance status

The identified substitutes (1755891 and 1827935) meet these core functional requirements while differing in termination style (solder vs. press-fit), housing material composition, and voltage rating specifications. These differences are documented in the parameter comparison table below.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1755891 is an active-status substitute with identical electrical ratings (12A IEC/UL, 300V UL) and mechanical compatibility. The primary distinction is termination style conversion from press-fit to solder, requiring PCB design modification. Housing material changes from PBT to polyamide (PA/nylon), with IEC voltage rating increased to 630V. ROHS3 compliance provides enhanced regulatory coverage compared to the obsolete main part.

Phoenix Contact 1827935 is an active-status substitute maintaining 12A current capacity and UL94 V-0 flammability rating. This option features liquid crystal polymer (LCP) housing material and reduced contact tail length (0.102" vs. 0.154"), necessitating PCB footprint verification. IEC voltage rating is 250V, which is lower than the main part's 320V specification. UL voltage and current ratings are not specified for this part.

Both substitutes are RoHS compliant and carry MSL 1 (Unlimited) moisture sensitivity classification, matching the original part's environmental specifications.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1755891 be used as a direct replacement for 1915893?

A: Functional compatibility exists for electrical and mechanical parameters. However, termination style differs (solder vs. press-fit), requiring PCB design modification. Housing material changes from PBT to polyamide. Verify PCB layout compatibility before implementation.

Q: What is the primary difference between the two substitute parts?

A: Part 1755891 maintains the original contact tail length (0.154") and offers higher IEC voltage rating (630V). Part 1827935 uses LCP housing material with reduced contact tail length (0.102") and lower IEC voltage rating (250V). Selection depends on specific voltage requirements and PCB footprint constraints.

Q: Are both substitutes suitable for high-voltage applications?

A: Part 1755891 supports 630V IEC rating, exceeding the original part's 320V specification. Part 1827935 operates at 250V IEC, below the original specification. Application voltage requirements determine appropriate selection.

Q: Do the substitute parts maintain RoHS compliance?

A: Yes. Part 1755891 carries ROHS3 compliance. Part 1827935 carries RoHS compliance. Both meet current regulatory requirements for restricted substance elimination.

Q: How does contact tail length affect PCB compatibility?

A: Contact tail length determines insertion depth into PCB plated through-holes. Part 1915893 and 1755891 both feature 0.154" (3.90mm) tails. Part 1827935 features 0.102" (2.60mm) tails, requiring verification that PCB hole depth accommodates reduced insertion depth.

Q: What packaging options are available for the substitute parts?

A: Both substitute parts (1755891 and 1827935) are supplied in bulk packaging, differing from the original part's unspecified packaging configuration.
