Phoenix Contact 1894930 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1894930 is an 8-position terminal block header with male pins, featuring a shrouded 4-side design and 2.50mm pitch for vertical through-hole mounting. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement planning. The part operates at 4A (IEC) / 4A (UL) with voltage ratings of 320V (IEC) and 125V (UL), utilizing solder termination and tin contact mating finish.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the Phoenix Contact 1894930 is determined by the following critical parameters: connector type (header with male pins, shrouded 4-side design), number of positions (8), positions per level (4), mounting method (vertical through-hole solder termination), and electrical ratings (current and voltage capacity). The Phoenix Contact 1844895 qualifies as a substitute based on matching these core functional characteristics. However, the following parameter differences must be acknowledged: pitch tolerance (2.50mm vs. 2.54mm), electrical ratings (4A/320V IEC vs. 6A/160V IEC), contact mating finish (tin vs. gold), housing material (polyamide vs. liquid crystal polymer), contact tail length (4.60mm vs. 2.00mm), and insulation height (17.50mm vs. 7.10mm). These differences indicate that while the 1844895 maintains the same connector topology and position count, physical and electrical characteristics diverge, requiring design-level evaluation before implementation.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1894930 is classified as obsolete, necessitating component substitution for new procurement. The Phoenix Contact 1844895 is an active product from the same manufacturer, offering improved compliance status (ROHS3 vs. RoHS Compliant) and enhanced contact mating finish (gold vs. tin), which provides superior corrosion resistance and contact reliability. Both parts maintain UL94 V-0 flammability rating and MSL 1 classification.

Selection of the 1844895 as a substitute requires evaluation of the following design-level considerations: the 2.54mm pitch differs from the original 2.50mm specification, which may impact PCB layout compatibility; the reduced contact tail length (2.00mm vs. 4.60mm) and insulation height (7.10mm vs. 17.50mm) necessitate verification of mounting clearance and solder joint accessibility; the housing material change from polyamide to liquid crystal polymer affects mechanical and thermal properties; and the electrical rating differential (6A/160V IEC vs. 4A/320V IEC) must be assessed against circuit requirements. The active product status of the 1844895 ensures ongoing availability and supply chain stability compared to the obsolete 1894930.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1844895 be used as a direct replacement for the 1894930?

A: Both parts share the same connector topology (8-position header, male pins, shrouded 4-side, vertical through-hole solder termination). However, pitch tolerance (2.50mm vs. 2.54mm), contact tail length (4.60mm vs. 2.00mm), and insulation height (17.50mm vs. 7.10mm) differences require PCB layout and mechanical clearance verification before implementation.

Q: What are the key electrical differences between these parts?

A: The 1894930 operates at 4A/320V (IEC) and 4A/125V (UL), while the 1844895 operates at 6A/160V (IEC) and 6A/150V (UL). The 1894930 provides higher voltage capacity under IEC standards, whereas the 1844895 provides higher current capacity. Circuit voltage and current requirements must be evaluated against both specifications.

Q: Why does the 1844895 have a gold contact mating finish instead of tin?

A: Gold plating provides enhanced corrosion resistance and improved contact reliability compared to tin finish. This is a material upgrade that typically improves long-term performance in demanding environments.

Q: Are there packaging differences between these parts?

A: The 1894930 packaging information is not specified in the provided data. The 1844895 is supplied in Cut Tape (CT) packaging. Packaging format should be confirmed with the supplier for procurement planning.

Q: What compliance certifications apply to both parts?

A: Both parts maintain UL94 V-0 material flammability rating and MSL 1 (Unlimited) moisture sensitivity classification. The 1844895 carries ROHS3 compliance, while the 1894930 carries RoHS compliance. Both are classified under ECCN EAR99 and HTSUS 8536.69.4040.

Q: Is the 1844895 suitable for applications requiring the original 1894930's voltage rating?

A: The 1894930 provides 320V (IEC) rating, while the 1844895 provides 160V (IEC) rating. Applications requiring the full 320V capacity cannot use the 1844895 without circuit redesign. Voltage requirements must be confirmed before substitution.
