Phoenix Contact 1899993 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1899993 is a 17-position terminal block header with male pins, shrouded on four sides, featuring 0.197" (5.00mm) pitch and 90° right-angle orientation for through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent substitute parts essential for ongoing design support and procurement continuity.

The primary function of this terminal block header is to provide a standardized connection interface for 17-conductor applications requiring press-fit termination with rated electrical performance of 12A at 400V (IEC) or 15A at 300V (UL).

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Phoenix Contact 1899993 are identified based on the following critical parameters that determine functional equivalence:

Core Matching Criteria:

• Number of positions: 17
• Pitch: 0.197" (5.00mm)
• Header orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting type: Through Hole
• Electrical ratings: Minimum 12A (IEC) / 15A (UL) and 300V (UL)
• Flammability rating: UL94 V-0
• RoHS compliance

Identified Substitutes:

1. Phoenix Contact 1757611 (COMBICON MSTBA Series) - Active product status with solder termination
2. Phoenix Contact 1836492 (COMBICON CCA Series) - Active product status with solder termination and extended operating temperature range

Both substitutes maintain the core electrical and mechanical specifications required for 17-position, 5.00mm pitch applications while offering active product availability and improved supply chain status compared to the obsolete 1899993.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement (Mechanical and Electrical Compatibility):

Both Phoenix Contact 1757611 and 1836492 are suitable substitutes for the obsolete 1899993 based on matching core specifications: 17 positions, 5.00mm pitch, 90° right-angle orientation, through-hole mounting, and equivalent electrical ratings. Both substitutes maintain UL94 V-0 flammability compliance and RoHS compliance status.

Key Consideration - Termination Style Change:

The primary difference between the main part and both substitutes is the termination method. The 1899993 uses press-fit termination, while both 1757611 and 1836492 employ solder termination. This change requires modification of the PCB design and assembly process. Press-fit termination allows direct insertion without soldering, whereas solder termination requires thermal processing during board assembly.

Selection Between Substitutes:

• Phoenix Contact 1757611: Maintains green color matching and identical electrical ratings to the main part. Suitable for standard operating environments.

• Phoenix Contact 1836492: Offers extended operating temperature range (-40°C to 100°C), higher UL current rating (16A vs. 15A), and specified copper alloy contact material. Recommended for applications requiring enhanced thermal performance or wider temperature operation. Note: Black color differs from the original green.

Both substitutes are active products with confirmed inventory availability, providing superior supply chain continuity compared to the obsolete 1899993.

Frequently Asked Questions (FAQ)

Q: Can the 1757611 or 1836492 be used as direct drop-in replacements for the 1899993?

A: Mechanical and electrical compatibility is confirmed for both substitutes. However, the termination style change from press-fit to solder requires PCB design modification and assembly process adjustment. The physical footprint and electrical performance remain compatible.

Q: What is the primary difference between the 1757611 and 1836492 substitutes?

A: The 1757611 maintains closer alignment with the original 1899993 specifications, including green color and identical electrical ratings. The 1836492 provides enhanced specifications with extended operating temperature range (-40°C to 100°C), higher UL current rating (16A), and specified copper alloy contacts, but differs in color (black) and has lower IEC voltage rating (320V vs. 400V).

Q: Does the change from press-fit to solder termination affect electrical performance?

A: No. Both termination methods provide equivalent electrical performance when properly executed. The change affects assembly methodology and PCB design requirements, not the electrical characteristics of the connection.

Q: Are both substitutes RoHS compliant?

A: Yes. Both Phoenix Contact 1757611 and 1836492 are RoHS compliant and maintain UL94 V-0 flammability rating, matching the compliance profile of the original 1899993.

Q: What is the significance of the different housing materials?

A: The main part uses Polybutylene Terephthalate (PBT), the 1757611 uses Polyamide (PA/Nylon), and the 1836492 uses Liquid Crystal Polymer (LCP). All three materials meet the UL94 V-0 flammability requirement. Material selection affects mechanical properties and thermal performance. The LCP material in the 1836492 supports the extended operating temperature range.

Q: Which substitute should be selected for new designs?

A: For new designs, either substitute is acceptable based on application requirements. The 1836492 is recommended for applications requiring extended temperature operation or higher current capacity. The 1757611 is suitable for standard operating environments and provides closer color matching to the original design.
