Phoenix Contact 1900057 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1900057 is a 23-position terminal block header with male pins, shrouded on four sides, featuring 0.197" (5.00mm) pitch and 90° right-angle orientation for through-hole mounting. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The part operates at IEC ratings of 12A/400V and UL ratings of 15A/300V, with press-fit termination and green polybutylene terephthalate (PBT) housing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1900057 is determined by the following critical parameters:

Core Compatibility Parameters:

• Number of positions: 23
• Pitch: 0.197" (5.00mm)
• Header orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting type: Through Hole
• Material flammability rating: UL94 V-0
• Electrical ratings: IEC 12A/400V minimum; UL 15A/300V minimum

Allowable Variations:

• Termination style: Press-fit (original) to solder (substitutes)
• Housing material: PBT (original) to polyamide (PA/nylon) or liquid crystal polymer (LCP)
• Contact tail length: Variation permitted within mechanical constraints
• Insulation height: Minor variation permitted (±0.01")
• Color: Green (original) to black (substitute)
• Product status: Obsolete (original) to active (substitutes)

The two identified substitutes (1757679 and 1836557) maintain all core compatibility parameters while offering active product status and alternative termination methods suitable for different assembly processes.

Parameter Comparison

Engineering Selection Recommendations

Part 1757679 (COMBICON MSTBA Series): This substitute is recommended for applications requiring active product status with maintained electrical specifications. The transition from press-fit to solder termination requires PCB design modification but provides equivalent electrical performance at IEC 12A/400V and UL 15A/300V ratings. Housing material change from PBT to polyamide (PA/nylon) maintains UL94 V-0 flammability compliance. ROHS3 compliance status provides enhanced regulatory alignment compared to the obsolete original part.

Part 1836557 (COMBICON CCA Series): This substitute offers the highest material performance with liquid crystal polymer (LCP) housing, providing superior thermal and mechanical properties. Operating temperature range of -40°C to 100°C is specified, whereas the original part does not provide this data. Electrical ratings remain compatible at IEC 12A/320V and UL 16A/300V. Solder termination applies. The shorter contact tail length (0.079" vs. 0.165") requires PCB footprint verification. Black color differentiates this option visually from the original green housing.

Both substitutes maintain the 23-position configuration, 5.00mm pitch, 90° right-angle orientation, through-hole mounting, and four-sided shrouding required for mechanical and electrical compatibility.

Frequently Asked Questions (FAQ)

Q: Can part 1757679 or 1836557 be used as direct drop-in replacements for the 1900057?

A: Mechanical compatibility is maintained for all three parts regarding position count, pitch, orientation, and mounting type. However, termination style differs: the original 1900057 uses press-fit termination, while both substitutes use solder termination. This requires PCB design modification. Contact tail length variation (1757679: 0.138", 1836557: 0.079" vs. original 0.165") must be verified against PCB hole depth and via placement.

Q: What are the electrical differences between the three parts?

A: All three parts meet minimum IEC 12A/400V and UL 15A/300V requirements. Part 1836557 specifies slightly lower IEC voltage (320V vs. 400V) but higher UL current (16A vs. 15A). For applications operating at the maximum IEC 400V specification, part 1757679 is preferred. For applications requiring specified operating temperature range, only part 1836557 provides this data (-40°C to 100°C).

Q: Does housing material affect electrical performance?

A: All three housing materials (PBT, polyamide, and LCP) maintain UL94 V-0 flammability compliance and equivalent electrical insulation properties. Material selection impacts thermal stability, mechanical rigidity, and environmental resistance. LCP (part 1836557) provides superior thermal performance; polyamide (part 1757679) offers cost efficiency; PBT (original 1900057) provides balanced performance.

Q: Are there packaging or inventory considerations?

A: The original part 1900057 is obsolete with 1084 pieces in stock. Both substitutes are active products with comparable inventory levels (1757679: 957 pieces; 1836557: 949 pieces). Packaging for substitutes is specified as bulk, whereas original packaging is not specified.

Q: Which substitute should be selected for new designs?

A: Part 1757679 is recommended for designs requiring closest electrical specification match (IEC 400V) with active product status. Part 1836557 is recommended for designs requiring specified operating temperature range and superior material performance. Both require solder termination capability in manufacturing processes.
