Phoenix Contact 1897102 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1897102 is a 3-position terminal block header with male pins, shrouded design, and 90° right-angle orientation. It features 0.138" (4.60mm) pitch spacing and press-fit termination for through-hole mounting. This component is classified as obsolete, making equivalent substitute parts necessary for ongoing design support and procurement continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1897102 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 3
• Pitch: 0.138" (4.60mm)
• Header Orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting Type: Through Hole
• Voltage - UL: 300 V
• Material Flammability Rating: UL94 V-0
• Contact Mating Finish: Tin
• Color: Green

Allowable Variation Parameters:

• Termination Style: Press-Fit (main part) may be substituted with Solder (substitute parts)
• Current Rating: IEC and UL ratings may vary within acceptable operational limits
• Housing Material: PBT (main part) may be substituted with Polyamide (PA66) in substitute parts
• Contact Tail Length: Minor dimensional variations (0.134" to 0.138") are acceptable
• Insulation Height: Minor dimensional variations (7.00mm to 7.30mm) are acceptable
• RoHS Status: RoHS Compliant and ROHS3 Compliant are both acceptable
• Product Status: Active substitute parts are preferred for obsolete main parts

Parameter Comparison

Engineering Selection Recommendations

Both substitute parts meet the core electrical and mechanical requirements for the obsolete Phoenix Contact 1897102.

Phoenix Contact 1844223:

• Active product status ensures long-term availability and supply chain continuity
• Identical pitch, position count, and orientation specifications
• Solder termination replaces press-fit; PCB design modification required
• Current rating increased to 12A (IEC), maintaining 8A (UL) compatibility
• PBT housing material matches original specification
• ROHS3 compliance exceeds original RoHS requirement
• Bulk packaging available

TE Connectivity 284512-3:

• Active product status with high inventory availability (8801 pcs)
• Identical pitch, position count, and orientation specifications
• Solder termination replaces press-fit; PCB design modification required
• Current rating of 11A (UL) exceeds original 8A specification
• Polyamide (PA66) housing material differs from original PBT
• Operating temperature range specified (-40°C ~ 110°C) provides environmental clarity
• ROHS3 compliance and REACH unaffected status
• Bulk packaging available

Frequently Asked Questions (FAQ)

Q: Can I use these substitute parts as direct drop-in replacements?

A: No. The main part uses press-fit termination, while both substitutes use solder termination. PCB footprint and assembly process modifications are required. Verify pad layout compatibility before implementation.

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

A: Press-fit termination uses mechanical insertion into plated through-holes without solder. Solder termination requires thermal bonding to PCB pads. These are distinct assembly methods requiring different PCB designs.

Q: Are the dimensional differences significant?

A: Contact tail length varies by 0.004" (0.10mm) and insulation height by up to 0.011" (0.30mm). These minor variations are within typical PCB design tolerances but should be verified against your specific board layout.

Q: Why does the TE Connectivity part have a different housing material?

A: Polyamide (PA66) and Polybutylene Terephthalate (PBT) are both UL94 V-0 rated materials suitable for terminal block applications. Material selection depends on environmental exposure and mechanical requirements in your application.

Q: Which substitute part should I choose?

A: Selection depends on your PCB design capability and supply requirements. Phoenix Contact 1844223 maintains material consistency with the original part. TE Connectivity 284512-3 offers higher current capacity and specified operating temperature range with greater inventory availability.

Q: Are both substitutes RoHS compliant?

A: Yes. Both substitute parts are ROHS3 compliant, exceeding the original RoHS compliance requirement.

Q: What is the contact material in each part?

A: The main part and Phoenix Contact 1844223 do not specify contact material. TE Connectivity 284512-3 uses Phosphor Bronze contacts.
