Phoenix Contact 1859632 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1859632 is a 14-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 equivalent substitute parts essential for ongoing system maintenance and new design implementations. The part operates at 12A current (IEC/UL) and 320V (IEC) / 300V (UL) voltage ratings, with press-fit termination and UL94 V-0 flammability rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1859632 is determined by the following critical parameters that must remain consistent:

• Electrical Compatibility: 14 positions, 0.200" (5.08mm) pitch, 12A current rating, and minimum 300V voltage rating (UL standard)
• Mechanical Compatibility: Vertical through-hole mounting, male pins with 4-side shrouding, contact tail length 0.154" (3.90mm), insulation height 0.472" (12.00mm)
• Material & Safety: UL94 V-0 flammability rating, tin contact mating finish
• Regulatory Compliance: RoHS compliance status

The substitute parts 1755859 and 1827896 maintain these core parameters while differing in termination style (solder vs. press-fit), housing material composition, and voltage ratings above the minimum threshold. Both substitutes are active products with current availability.

Parameter Comparison

Engineering Selection Recommendations

Part 1755859 is suitable for applications requiring solder termination with enhanced voltage rating (630V IEC). The polyamide housing and ROHS3 compliance provide compatibility with current regulatory requirements. This substitute is recommended for new designs where solder attachment is preferred over press-fit installation.

Part 1827896 offers solder termination with liquid crystal polymer housing, providing superior thermal and chemical resistance. The reduced contact tail length (0.102" vs. 0.154") requires verification of PCB layout compatibility. This substitute is appropriate for applications with elevated environmental demands while maintaining the 12A current rating and UL94 V-0 safety standard.

Both substitutes maintain active product status, ensuring long-term availability and supply chain stability compared to the obsolete 1859632.

Frequently Asked Questions (FAQ)

Q: Can 1755859 or 1827896 directly replace 1859632 in existing assemblies?

A: Mechanical and electrical compatibility is maintained across all three parts for the 14-position, 5.08mm pitch configuration. However, termination style differs: 1859632 uses press-fit while 1755859 and 1827896 require solder attachment. PCB design modifications may be necessary, particularly for 1827896 due to its shorter contact tail length (0.102" vs. 0.154").

Q: What are the voltage rating differences between these parts?

A: The 1859632 operates at 320V (IEC) / 300V (UL). Substitute 1755859 provides 630V (IEC) / 300V (UL), offering higher voltage margin. Substitute 1827896 operates at 250V (IEC), which remains above the 300V UL minimum but below the original IEC rating. Selection depends on circuit voltage requirements.

Q: Are there compliance differences between the substitutes?

A: All three parts maintain UL94 V-0 flammability rating and MSL 1 (Unlimited) moisture sensitivity. The 1859632 and 1827896 are RoHS Compliant, while 1755859 is ROHS3 Compliant. Both compliance levels are acceptable for current applications; ROHS3 represents the updated standard.

Q: How does the housing material affect performance?

A: The 1859632 uses polybutylene terephthalate (PBT), 1755859 uses polyamide (PA/Nylon), and 1827896 uses liquid crystal polymer (LCP). LCP offers superior thermal stability and chemical resistance, while PA provides cost efficiency. Material selection should align with operating environment and temperature requirements.

Q: What is the impact of different contact tail lengths?

A: The 1859632 and 1755859 share 0.154" (3.90mm) contact tail length, ensuring identical PCB hole depth requirements. The 1827896 has a shorter 0.102" (2.60mm) tail, which may require PCB design adjustment if through-hole depth is critical to assembly process or mechanical retention.
