Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1899647 is determined by the following critical parameters:

Core Compatibility Parameters:

• Number of positions: 5
• Pitch: 0.200" (5.08mm)
• Header orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting type: Through Hole
• Current rating (IEC): 12A minimum
• Voltage rating (IEC): 400 V minimum
• Material flammability: UL94 V-0
• Connector interface: COMBICON series compatibility

Variable Parameters Allowing Substitution:

• Termination style: Press-fit (original) vs. Solder (substitutes)
• Series designation: EMSTB (original) vs. MSTB or CC (substitutes)
• Housing material: PBT (original) vs. LCP (substitute 1792656)
• Contact tail length: Varies by termination method
• Product status: Obsolete (original) vs. Active (substitutes)
• Color: Green (original) vs. Black (substitute 1792656)

The identified substitutes maintain electrical and mechanical compatibility through matching core parameters while offering active product status and modern compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1776537 (COMBICON MSTB Series)

Part 1776537 is the primary substitute for the obsolete 1899647. Both components maintain identical electrical specifications (12A IEC, 400V IEC, 15A UL, 300V UL) and mechanical compatibility (5 positions, 5.08mm pitch, 90° orientation, through-hole mounting). The primary difference is termination style: 1776537 uses solder termination versus the press-fit design of 1899647. This part carries active product status and ROHS3 compliance, ensuring long-term availability and regulatory alignment. The housing material remains PBT with UL94 V-0 rating, and color consistency (green) supports visual identification in existing designs.

Phoenix Contact 1792656 (COMBICON CC Series)

Part 1792656 serves as an alternative substitute with active product status and ROHS3 compliance. This component maintains core electrical and mechanical parameters but introduces material and electrical specification variations. The housing material is Liquid Crystal Polymer (LCP) instead of PBT, and the UL current rating is reduced to 10A (versus 15A for the main part and 1776537). The contact tail length is significantly shorter (0.102" vs. 0.165"), and the housing color is black rather than green. Selection of 1792656 is appropriate only when the reduced UL current rating (10A) meets application requirements and when PCB layout accommodates the shorter contact tail length.

Compliance and Availability Considerations

Both substitutes are active products with current compliance certifications (ROHS3, REACH Unaffected where applicable), addressing the obsolescence status of the original 1899647. Inventory availability is confirmed for both alternatives, supporting immediate procurement for production and maintenance applications.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1776537 directly replace 1899647 in existing designs?

A: Yes, for applications where termination method can be adapted. The 1776537 maintains identical electrical ratings (12A IEC, 400V IEC, 15A UL, 300V UL), mechanical configuration (5 positions, 5.08mm pitch, 90° right-angle), and housing material (PBT, UL94 V-0). The primary difference is solder termination versus press-fit. If the PCB design accommodates solder termination and the contact tail length (0.138" vs. 0.165") fits the application, direct substitution is feasible.

Q: What is the impact of switching from press-fit to solder termination?

A: Termination style affects assembly process and mechanical connection method. Press-fit (1899647) provides tool-less insertion into plated through-holes. Solder termination (1776537, 1792656) requires reflow or wave soldering processes. Both methods achieve equivalent electrical and mechanical reliability when properly executed. PCB design must accommodate the respective termination requirements.

Q: Is Phoenix Contact 1792656 suitable as a substitute if UL current rating is critical?

A: No, if the application requires 15A UL current capacity. The 1792656 is rated for 10A UL, which is lower than both the original 1899647 (15A UL) and the 1776537 (15A UL). The IEC current rating remains 12A across all three parts. Selection of 1792656 is limited to applications where 10A UL current capacity is sufficient.

Q: Does housing material change affect electrical performance?

A: No. Both PBT (1899647, 1776537) and LCP (1792656) housing materials maintain UL94 V-0 flammability rating and equivalent electrical insulation properties. Material selection affects mechanical properties, thermal performance, and chemical resistance, not electrical function. Both materials are suitable for standard industrial terminal block applications.

Q: Why does contact tail length vary among these parts?

A: Contact tail length is determined by termination style. Press-fit termination (1899647) requires longer tails (0.165") for insertion depth into plated through-holes. Solder termination (1776537, 1792656) requires shorter tails (0.138", 0.102") for reflow or wave soldering processes. PCB design must accommodate the specific tail length of the selected part.

Q: Are all three parts compatible with COMBICON series connectors?

A: Yes. All three parts are Phoenix Contact COMBICON series headers (EMSTB, MSTB, CC) with identical 5.08mm pitch and 90° orientation, ensuring mechanical and electrical compatibility with corresponding COMBICON receptacles and mating connectors.

Q: What is the significance of active versus obsolete product status?

A: Obsolete status (1899647) indicates the manufacturer no longer produces or supports the part. Active status (1776537, 1792656) confirms ongoing production, availability, and manufacturer support. For new designs and long-term maintenance, active products are preferred to ensure supply chain continuity and access to technical support.
