Phoenix Contact 1859548 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1859548 is a 5-position terminal block header with male pins, shrouded on 4 sides, featuring 0.200" (5.08mm) pitch vertical through-hole mounting. This component is part of the COMBICON EMSTBVA series and is currently classified as obsolete. Due to its obsolete status, identifying equivalent and substitute parts is essential for ongoing system maintenance, repairs, and new designs requiring compatible alternatives.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1859548 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 5
• Pitch: 0.200" (5.08mm)
• Header Orientation: Vertical
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting Type: Through Hole
• Insulation Height: 0.472" (12.00mm)

Electrical Compatibility Parameters:

• Current - IEC: 12A minimum
• Voltage - IEC: 320 V minimum
• Current - UL: 12 A minimum
• Voltage - UL: 300 V minimum

Compliance Parameters:

• Material Flammability Rating: UL94 V-0
• RoHS Status: ROHS3 Compliant or equivalent

The two substitute parts identified (1755765 and 1955882) meet these mandatory parameters. Differences in termination style (Press-Fit vs. Solder), housing material composition, and contact tail length represent acceptable variations that do not prevent functional substitution in applications where the original 1859548 was specified.

Parameter Comparison

Engineering Selection Recommendations

1755765 (COMBICON MSTBVA Series)

Part 1755765 is the primary recommended substitute for the obsolete 1859548. Both components share identical mechanical dimensions (5 positions, 5.08mm pitch, 0.472" insulation height, 0.154" contact tail length) and electrical ratings under UL standards (12A at 300V). The 1755765 offers superior IEC voltage rating (630V vs. 320V) and maintains active product status with ROHS3 compliance. The primary difference is termination style: 1755765 uses solder termination versus the press-fit design of 1859548. This substitution is suitable for applications where PCB-level soldering is feasible and preferred for long-term reliability.

1955882 (COMBICON CCVA Series)

Part 1955882 serves as an alternative substitute with active product status and RoHS compliance. This component maintains the same mechanical footprint and core electrical specifications. However, the 1955882 exhibits a reduced UL current rating (10A vs. 12A) and a shorter contact tail length (0.102" vs. 0.154"), which may impact PCB insertion depth and mechanical fit. The housing material (Liquid Crystal Polymer) differs from both the main part and the primary substitute. Selection of 1955882 is appropriate only when the reduced current rating and shorter contact tail are compatible with the application requirements.

Compliance Basis

Both substitute parts maintain UL94 V-0 flammability ratings and RoHS compliance, ensuring regulatory alignment with the original 1859548. The active product status of both substitutes provides supply chain continuity and technical support availability.

Frequently Asked Questions (FAQ)

Q: Can I directly replace 1859548 with 1755765 on an existing PCB?

A: Direct replacement requires PCB modification. The 1859548 uses press-fit termination (designed for mechanical insertion into plated through-holes), while 1755765 requires solder termination. The contact tail lengths are identical (0.154"), but the termination method necessitates different PCB pad designs and assembly processes.

Q: What is the key difference between 1755765 and 1955882?

A: The primary differences are contact tail length (0.154" vs. 0.102"), UL current rating (12A vs. 10A), and housing material (Polyamide vs. Liquid Crystal Polymer). Both are electrically compatible at 300V UL rating, but 1955882's shorter contact tail may affect insertion depth on legacy PCBs designed for 1859548.

Q: Is 1755765 suitable for high-voltage applications?

A: 1755765 supports 630V IEC rating, exceeding the original 1859548 (320V IEC). However, application suitability depends on the specific circuit design and safety requirements. The UL voltage rating remains 300V for both components.

Q: Why is 1859548 obsolete?

A: Product obsolescence is determined by the manufacturer. The availability of active alternatives (1755765 and 1955882) indicates that Phoenix Contact has transitioned to newer series designs while maintaining functional compatibility.

Q: Can I use 1955882 in applications requiring 12A current?

A: No. The 1955882 is rated for 10A under UL standards, which is below the 12A requirement of the original 1859548. Selection of 1955882 is limited to applications with maximum 10A current demand.

Q: Are all three parts RoHS compliant?

A: Yes. The 1859548 is ROHS3 compliant, 1755765 is ROHS3 compliant, and 1955882 is RoHS compliant. All three meet current environmental regulations.

Q: What packaging is available for the substitute parts?

A: 1755765 and 1955882 are supplied in bulk packaging, differing from the original 1859548 specification. Verify packaging requirements with your procurement process.
