Phoenix Contact 1908855 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1908855 is an 11-position terminal block header with male pins, shrouded on four sides, featuring 0.150" (3.81mm) pitch and 90° right-angle through-hole mounting. This component is classified as obsolete, making identification of equivalent and substitute parts essential for ongoing design support and procurement continuity. The part operates at 8A (IEC) / 8A (UL) and 250V (IEC) / 300V (UL), with UL94 V-0 flammability rating and RoHS compliance.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1908855 is determined by strict equivalence across the following critical parameters: 11-position count, 0.150" (3.81mm) pitch, 90° right-angle orientation, male pin configuration with four-side shrouding, solder termination, and through-hole mounting. All substitute parts must maintain UL94 V-0 flammability compliance and RoHS certification status.

Two substitute parts meet these criteria:

Direct Equivalent (Phoenix Contact 1722079): Identical electrical and mechanical specifications with active product status. Housing material differs (Liquid Crystal Polymer vs. Polyamide), and contact tail length and insulation height show minor dimensional variation within acceptable tolerance ranges.

Cross-Manufacturer Equivalent (TE Connectivity 1-284513-1): Meets all core functional parameters with active product status. Current rating increases to 11A (UL), voltage rating matches at 300V (UL). Housing material is Polyamide (PA66), contact material is Phosphor Bronze, and operating temperature range is specified as -40°C ~ 110°C. Dimensional parameters (contact tail length, insulation height) align with the main part.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1722079 is the primary substitute for the obsolete 1908855. Both parts belong to the COMBICON MC series and maintain identical electrical specifications. The 1722079 carries active product status, ensuring long-term availability and supply chain continuity. Housing material composition differs (Liquid Crystal Polymer versus glass-filled Polyamide), and contact tail length is reduced by 0.032" (0.80mm), with insulation height reduced by 0.013" (0.34mm). These dimensional variations remain within standard mechanical tolerance ranges for terminal block headers and do not affect functional compatibility in standard through-hole PCB applications.

TE Connectivity 1-284513-1 serves as a cross-manufacturer equivalent when Phoenix Contact 1722079 is unavailable. This part exceeds the original current rating at 11A (UL) versus 8A, providing enhanced electrical capacity. Operating temperature range is explicitly defined as -40°C ~ 110°C. Housing material is standard Polyamide (PA66), and contact material is Phosphor Bronze. Contact tail length matches the original part at 0.134" (3.40mm), and insulation height is 0.287" (7.30mm), closely aligned with the main part. The part carries ROHS3 compliance, meeting current regulatory requirements.

Both substitutes maintain UL94 V-0 flammability rating, MSL 1 moisture sensitivity, and EAR99 export classification, ensuring regulatory and compliance equivalence.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1722079 be used as a direct replacement for 1908855 in existing designs?

A: Yes. Both parts share identical electrical ratings (8A at 300V UL), pitch (0.150"), position count (11), and core mechanical configuration (90° right-angle, male pins, four-side shrouded, solder termination, through-hole mounting). Minor dimensional differences in contact tail length and insulation height fall within standard mechanical tolerances and do not affect PCB layout or mating compatibility.

Q: What are the key differences between the Phoenix Contact 1722079 and TE Connectivity 1-284513-1?

A: Both parts meet functional equivalence criteria. The 1722079 maintains the original 8A current rating and belongs to the COMBICON MC series. The 1-284513-1 increases current capacity to 11A, includes an operating temperature range specification (-40°C ~ 110°C), and uses Phosphor Bronze contacts. Housing materials differ: 1722079 uses Liquid Crystal Polymer, while 1-284513-1 uses standard Polyamide (PA66). Contact tail length is 0.102" (1722079) versus 0.134" (1-284513-1).

Q: Are there any compliance or certification differences between these parts?

A: All three parts maintain UL94 V-0 flammability rating, MSL 1 moisture sensitivity, and EAR99 export classification. The 1908855 and 1722079 carry RoHS Compliant status, while the 1-284513-1 carries ROHS3 Compliant status, reflecting current regulatory standards. All parts share identical HTSUS classification (8536.69.4040).

Q: Which substitute should be selected for new designs?

A: Phoenix Contact 1722079 is recommended for designs requiring COMBICON MC series continuity and exact electrical specification matching. TE Connectivity 1-284513-1 is suitable when higher current capacity (11A) is acceptable and cross-manufacturer sourcing provides supply chain advantages. Both parts carry active product status and ensure long-term availability.

Q: Do dimensional differences affect PCB layout compatibility?

A: Contact tail length and insulation height variations are minor (0.032" and 0.013" respectively) and remain within standard mechanical tolerance ranges for terminal block headers. PCB footprints designed for the 1908855 accommodate both substitute parts without layout modification.
