Phoenix Contact 1914894 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1914894 is a 6-position terminal block header with male pins, shrouded on 4 sides, featuring 0.197" (5.00mm) pitch vertical through-hole mounting. This component is classified as obsolete, making identification of suitable substitute parts essential for ongoing design support and procurement continuity. The part operates at 12A (IEC) / 12A (UL) and 320V (IEC) / 300V (UL), with press-fit termination and green polybutylene terephthalate (PBT) housing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1914894 is determined by the following critical parameters:

• Electrical Compatibility: Current rating (IEC/UL), voltage rating (IEC/UL), and contact material must support equivalent or higher performance
• Mechanical Compatibility: Number of positions (6), pitch (5.00mm), header orientation (vertical), shrouding configuration (4-side), and through-hole mounting must be identical
• Physical Compatibility: Contact tail length and insulation height must accommodate existing PCB layouts and mating connectors
• Termination Interface: Substitute parts may employ different termination styles (solder vs. press-fit) provided the electrical and mechanical interfaces remain compatible with the application

Two active substitute parts meet these criteria:

1837064 (COMBICON CCVA series) and 1755558 (COMBICON MSTBVA series) both maintain the 6-position, 5.00mm pitch vertical configuration with identical shrouding and insulation height. Both are active products with current availability and enhanced compliance certifications.

Parameter Comparison

Engineering Selection Recommendations

1755558 (COMBICON MSTBVA) is the primary substitute for applications requiring direct electrical and mechanical compatibility. This part maintains identical pitch, position count, shrouding, and contact tail length. The solder termination replaces the press-fit design, requiring PCB layout modification. Voltage rating increases to 400V (IEC), exceeding the original specification. RoHS3 compliance and active product status ensure long-term availability. Housing material transitions from PBT to polyamide (PA/nylon), which may affect thermal or chemical resistance in specific environments.

1837064 (COMBICON CCVA) provides an alternative with enhanced current rating (16A UL) and liquid crystal polymer (LCP) housing. The reduced contact tail length (0.079" vs. 0.154") requires PCB design verification to ensure proper mating depth with connector receptacles. This part is suitable for applications where the shorter tail length is compatible with existing connector specifications. Active product status and ROHS3 compliance support procurement continuity.

Both substitutes are active products with documented inventory availability, addressing the obsolescence of the original 1914894 part.

Frequently Asked Questions (FAQ)

Q: Can 1755558 or 1837064 be used as direct drop-in replacements for 1914894?

A: Mechanical and electrical compatibility is confirmed for both substitutes in terms of position count, pitch, shrouding, and voltage/current ratings. However, termination style differs: 1914894 uses press-fit termination, while both substitutes use solder termination. This requires PCB layout modification. Additionally, 1837064 has a shorter contact tail length (0.079" vs. 0.154"), which must be verified against connector receptacle specifications.

Q: What is the impact of housing material differences?

A: The original 1914894 uses polybutylene terephthalate (PBT). Substitute 1755558 uses polyamide (PA/nylon), and 1837064 uses liquid crystal polymer (LCP). Material selection affects thermal stability, chemical resistance, and mechanical properties. Application-specific environmental conditions (temperature, humidity, chemical exposure) should be evaluated to confirm material suitability.

Q: Are there compliance differences between the main part and substitutes?

A: The original 1914894 is RoHS Compliant. Both substitutes are ROHS3 Compliant, representing an enhanced compliance standard. Both substitutes carry REACH Unaffected status. Flammability rating (UL94 V-0) is confirmed for 1914894 and 1755558; 1837064 does not specify this rating.

Q: Which substitute should be selected for new designs?

A: For applications where contact tail length is not a constraint, 1755558 is recommended due to identical contact tail length (3.90mm) and established compatibility with standard connector receptacles. For applications requiring higher current capacity (16A UL), 1837064 is suitable provided the shorter contact tail (2.00mm) is compatible with mating connector specifications.

Q: What packaging options are available?

A: 1755558 and 1837064 are supplied in bulk packaging. Inventory availability: 1755558 (1677 pcs), 1837064 (818 pcs).
