Phoenix Contact 1899744 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1899744 is a 15-position terminal block header with male pins, shrouded on four sides, featuring 0.200" (5.08mm) pitch and 90° right-angle through-hole mounting. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing design support and procurement continuity. The part operates at IEC ratings of 12A/400V and UL ratings of 15A/300V, with press-fit termination and tin-plated contacts housed in UL94 V-0 rated polybutylene terephthalate (PBT) material.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1899744 is determined by the following critical parameters:

Core Compatibility Parameters:

• Number of positions: 15
• Pitch: 0.200" (5.08mm)
• Header orientation: 90°, Right Angle
• Mounting type: Through Hole
• Type: Header, Male Pins, Shrouded (4 Side)
• Electrical ratings: Minimum 12A IEC / 400V IEC and 15A UL / 300V UL

Allowed Variations:

• Termination style: Press-fit or solder acceptable
• Series designation: Different COMBICON series permitted
• Housing material: PBT or alternative polymer acceptable
• Contact tail length: Variation permitted within mechanical constraints
• Color: Variation permitted
• Product status: Active status preferred for obsolete parts

The two identified substitute parts meet these core compatibility criteria while offering active product status and alternative termination technologies.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1776634 (COMBICON MSTB Series)

Part 1776634 is the primary substitute for the obsolete 1899744. Both parts maintain identical electrical specifications (12A IEC / 400V IEC, 15A UL / 300V UL), identical pitch and position count, and identical insulation height. The primary difference is termination technology: 1776634 uses solder termination instead of press-fit. Both parts feature PBT housing with UL94 V-0 flammability rating and tin-plated contacts. This part carries active product status and is available in bulk packaging.

Phoenix Contact 1827540 (COMBICON CC Series)

Part 1827540 serves as a secondary substitute option. It maintains core mechanical compatibility (15 positions, 0.200" pitch, 90° right angle, through-hole mounting) and meets or exceeds electrical requirements (12A IEC / 320V IEC, 16A UL / 300V UL). The housing material differs (liquid crystal polymer instead of PBT), and contact tail length is shorter (0.102" versus 0.165"). This part also features active product status and solder termination. The reduced IEC voltage rating (320V versus 400V) requires evaluation against application requirements.

Both substitute parts are RoHS compliant with MSL 1 rating and maintain the same ECCN and HTSUS classifications as the original part.

Frequently Asked Questions (FAQ)

Q: Can I use part 1776634 as a direct replacement for 1899744?

A: Part 1776634 is mechanically and electrically compatible. The primary difference is termination method: 1776634 uses solder termination while 1899744 uses press-fit. PCB design must accommodate solder termination instead of press-fit mounting. Both parts share identical pitch, position count, electrical ratings, and insulation height.

Q: What is the difference between press-fit and solder termination?

A: Press-fit termination (1899744) uses mechanical insertion into plated through-holes. Solder termination (1776634, 1827540) requires wave or reflow soldering to the PCB. Press-fit offers faster assembly but requires precise hole sizing. Solder termination provides stronger mechanical connection and is more forgiving of hole tolerance variations.

Q: Is part 1827540 suitable for my application?

A: Part 1827540 is mechanically compatible but has a lower IEC voltage rating (320V versus 400V). If your application requires 400V IEC operation, 1827540 is not suitable. For applications operating at or below 320V IEC and 300V UL, 1827540 is acceptable. The housing material (LCP) and shorter contact tail length must also be evaluated for mechanical fit.

Q: Why do the substitute parts have different colors?

A: Color is a cosmetic parameter that does not affect electrical or mechanical function. Part 1776634 maintains the original green color, while 1827540 is black. Color selection does not impact substitution eligibility.

Q: Are all three parts RoHS compliant?

A: Yes. All three parts (1899744, 1776634, 1827540) are RoHS compliant with MSL 1 (unlimited) moisture sensitivity level.

Q: What is the inventory status of these parts?

A: Part 1899744 (obsolete) has 1083 pieces in stock. Part 1776634 (active) has 973 pieces in stock. Part 1827540 (active) has 671 pieces in stock. Active parts are recommended for new designs due to ongoing manufacturer support.
