Phoenix Contact 1880494 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1880494 is a 21-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 system maintenance and new design implementations. The part operates at 12A (IEC) / 15A (UL) and 400V (IEC) / 300V (UL), with press-fit termination and UL94 V-0 flammability rating.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1880494 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Number of positions: 21
• 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): 400V minimum
• Flammability rating: UL94 V-0

Allowable Variations:

• Termination style: Press-fit or solder acceptable
• Housing material: PBT, Polyamide (PA/Nylon), or Liquid Crystal Polymer (LCP)
• Contact tail length: Minor variations permitted within mechanical envelope constraints
• Insulation height: Tolerance within ±0.010" (0.25mm)
• Product status: Active preferred over obsolete

The two identified substitute parts (1757433 and 1827728) meet all mandatory matching parameters while offering active product status and improved material options.

Parameter Comparison

Engineering Selection Recommendations

Part 1757433 (COMBICON MSTBA Series): This substitute offers the closest electrical equivalence to the 1880494, maintaining identical current (12A IEC, 15A UL) and voltage (400V IEC, 300V UL) ratings. The primary difference is termination style conversion from press-fit to solder, requiring PCB design modification. Housing material changes from PBT to polyamide (PA/Nylon), which remains UL94 V-0 compliant. Active product status ensures long-term availability. Contact tail length reduction (0.138" vs. 0.165") requires verification of PCB hole depth compatibility.

Part 1827728 (COMBICON CCA Series): This substitute maintains mechanical and electrical compatibility for 21-position, 5.08mm pitch applications with solder termination. Voltage rating reduction to 250V (IEC) represents a design constraint that must be evaluated against system requirements. The LCP housing material provides superior thermal and chemical resistance compared to PBT. Contact tail length is significantly shorter (0.102"), requiring careful PCB design review. Active product status and RoHS compliance support long-term supply chain stability.

Selection Criteria:

• For applications requiring 400V IEC rating: Select 1757433
• For applications with 250V IEC maximum requirement: 1827728 is acceptable
• For PCB designs with solder termination capability: Both 1757433 and 1827728 are suitable
• For designs requiring press-fit termination: Neither substitute is compatible; alternative sourcing required

Frequently Asked Questions (FAQ)

Q: Can the 1880494 be directly replaced with 1757433 or 1827728 without PCB modification?

A: Direct replacement without modification is not possible. The 1880494 uses press-fit termination, while both substitutes require solder termination. PCB design changes are necessary, including hole diameter and depth adjustments. Mechanical envelope verification is required due to contact tail length variations.

Q: What is the impact of housing material changes on thermal performance?

A: The 1880494 uses PBT, 1757433 uses polyamide (PA/Nylon), and 1827728 uses LCP. All materials maintain UL94 V-0 flammability compliance. LCP (1827728) offers superior thermal stability; polyamide (1757433) provides adequate thermal performance for standard applications. Material selection should be based on operating temperature range and thermal cycling requirements.

Q: Is the voltage rating reduction from 400V to 250V (IEC) in part 1827728 a limiting factor?

A: The voltage rating reduction is application-dependent. If the system operates at or below 250V (IEC), part 1827728 is fully qualified. For systems requiring 400V (IEC) operation, part 1827728 is not suitable; part 1757433 must be selected.

Q: How do contact tail length variations affect PCB compatibility?

A: Contact tail lengths differ: 1880494 (0.165"), 1757433 (0.138"), and 1827728 (0.102"). These variations require PCB hole depth verification. Shorter tail lengths may not provide adequate solder joint formation if PCB holes are designed for the original 0.165" specification. PCB design review and potential modification are necessary.

Q: Are all three parts RoHS compliant?

A: Yes. The 1880494 is RoHS Compliant, 1757433 is ROHS3 Compliant, and 1827728 is RoHS Compliant. All parts meet current RoHS requirements for new designs.

Q: What is the difference between COMBICON EMSTBA, MSTBA, and CCA series?

A: These are distinct Phoenix Contact product series within the COMBICON terminal block family. EMSTBA (1880494) is obsolete. MSTBA (1757433) and CCA (1827728) are active series with different material compositions and performance characteristics. Series selection should align with application requirements and long-term supply chain strategy.
