Phoenix Contact 1915864 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1915864 is a 19-position terminal block header with male pins, shrouded on four sides, designed for 0.200" (5.08mm) pitch vertical through-hole mounting. This component is part of the COMBICON EMSTBV series and carries an obsolete product status. The part features press-fit termination, UL94 V-0 flammability rating, and tin-plated mating finish suitable for industrial control and power distribution applications.

Due to its obsolete status, equivalent substitute parts from the active Phoenix Contact product lines are available to maintain design compatibility while ensuring continued supply and support.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1915864 is determined by the following critical parameters:

• Position Count & Pitch: All substitute parts must maintain 19 positions at 0.200" (5.08mm) pitch
• Header Type & Orientation: Male pins, shrouded (4 side), vertical orientation required
• Mounting Method: Through-hole mounting maintained across all substitutes
• Electrical Ratings: Minimum IEC current rating of 12A and voltage rating of 320V (IEC) / 300V (UL)
• Flammability & Housing: UL94 V-0 rating and compatible housing materials (PBT or LCP)
• Contact Finish: Tin-plated mating finish for corrosion resistance

The two substitute parts listed below meet these core substitution criteria while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1777248 is the primary substitute for the 1915864. Both parts share identical mechanical dimensions (contact tail length 0.154", insulation height 0.472"), PBT housing material, and electrical ratings. The 1777248 offers active product status, RoHS compliance, and higher IEC voltage rating (630V vs. 320V), providing enhanced design margin. The termination style differs (solder vs. press-fit), requiring PCB layout adjustment but maintaining full electrical and mechanical compatibility.

Phoenix Contact 1827825 serves as an alternative substitute with active product status and RoHS compliance. This part features LCP housing material instead of PBT, higher UL current rating (16A vs. 12A), and a shorter contact tail length (0.102" vs. 0.154"). The reduced contact tail length requires verification against PCB hole depth specifications. The LCP housing provides superior thermal and chemical resistance compared to PBT.

Both substitutes maintain the 19-position, 0.200" pitch configuration, vertical orientation, and four-side shrouding required for direct functional replacement. Selection between 1777248 and 1827825 depends on PCB design constraints (contact tail length), material requirements (PBT vs. LCP), and electrical margin needs.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1777248 directly replace 1915864 in existing designs?

A: Mechanical and electrical compatibility is confirmed. The primary design change is termination method: 1915864 uses press-fit termination while 1777248 requires solder termination. PCB layout must be modified to accommodate solder pads instead of press-fit holes. All other dimensions and electrical ratings are compatible.

Q: What is the difference between 1777248 and 1827825?

A: Both are active substitutes with identical position count and pitch. Key differences are housing material (1777248 uses PBT; 1827825 uses LCP), contact tail length (1777248 is 0.154"; 1827825 is 0.102"), and UL current rating (1777248 is 12A; 1827825 is 16A). Contact tail length affects PCB hole depth compatibility.

Q: Are both substitute parts RoHS compliant?

A: Yes. Both 1777248 and 1827825 carry RoHS Compliant status. The original 1915864 does not specify RoHS compliance.

Q: What is the impact of housing material differences?

A: 1777248 uses Polybutylene Terephthalate (PBT) while 1827825 uses Liquid Crystal Polymer (LCP). Both materials meet UL94 V-0 flammability requirements. LCP offers superior thermal stability and chemical resistance; PBT provides cost efficiency and established reliability history.

Q: Can I use 1827825 if my PCB is designed for the original 1915864 contact tail length?

A: Contact tail length differs: 1915864 and 1777248 are 0.154" (3.90mm); 1827825 is 0.102" (2.60mm). If PCB holes are designed for 0.154" depth, 1827825 may not achieve full insertion. PCB design review is required before substitution.

Q: What are the voltage and current rating differences?

A: All three parts maintain 12A IEC current and 300V UL voltage. IEC voltage differs: 1915864 is 320V; 1777248 is 630V; 1827825 is 320V. UL current differs: 1915864 and 1777248 are 12A; 1827825 is 16A. Application requirements determine which ratings are necessary.
