Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the Phoenix Contact 1900002 are identified based on the following critical parameters that determine functional equivalence:

Primary Matching Criteria:

• Number of positions: 18
• Pitch: 0.197" (5.00mm)
• Header orientation: 90°, Right Angle
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting type: Through Hole
• Current rating (IEC): 12A minimum
• Voltage rating (IEC): 400V minimum
• Material flammability: UL94 V-0
• Contact mating finish: Tin

Acceptable Variations:

• Termination style: Press-fit or solder acceptable
• Housing material: PBT, Polyamide (PA/Nylon), or Liquid Crystal Polymer (LCP)
• Contact tail length: Variation acceptable within mechanical constraints
• Product status: Active preferred over obsolete

The identified substitutes (1757624 and 1836502) maintain electrical performance equivalence while offering active product status and improved availability.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1757624 (COMBICON MSTBA Series)

Part 1757624 is an active product offering direct electrical equivalence to the obsolete 1900002. Both components maintain identical IEC current (12A) and voltage (400V) ratings, UL ratings (15A/300V), and UL94 V-0 flammability compliance. The primary difference is termination style: 1757624 uses solder termination versus the press-fit design of 1900002. Housing material differs (Polyamide/Nylon versus PBT), and contact tail length is reduced (4.60mm versus 4.19mm). ROHS3 compliance status is confirmed. This substitute is suitable for applications where solder termination is acceptable and PCB layout accommodates the shorter contact tail.

Phoenix Contact 1836502 (COMBICON CCA Series)

Part 1836502 is an active product with electrical performance suitable for most applications requiring the 1900002. This component maintains 12A IEC current rating and 300V UL voltage rating, with UL94 V-0 flammability compliance. IEC voltage rating is reduced to 320V (versus 400V on 1900002), and UL current rating is increased to 16A. Termination is solder-based. Housing material is Liquid Crystal Polymer (LCP), and contact tail length is significantly shorter (2.00mm). Operating temperature range is specified (-40°C to 100°C). This substitute is appropriate for applications operating within 320V IEC voltage limits and where the shorter contact tail is mechanically compatible.

Selection Basis:

Both substitutes are active products with confirmed RoHS compliance and UL94 V-0 flammability ratings. Selection between 1757624 and 1836502 depends on specific application voltage requirements (400V IEC preferred = 1757624; 320V IEC acceptable = 1836502) and PCB layout constraints related to contact tail length and housing material compatibility.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1757624 directly replace 1900002 in existing designs?

A: Electrical substitution is valid. Both components maintain 12A/400V IEC ratings and 15A/300V UL ratings with identical pitch (5.00mm), position count (18), and shrouded male pin configuration. The primary consideration is termination method: 1757624 uses solder termination while 1900002 uses press-fit. PCB design must accommodate solder pads instead of press-fit holes. Contact tail length differs (4.60mm versus 4.19mm), requiring verification of PCB layout compatibility.

Q: What is the voltage difference between 1757624 and 1836502?

A: Both components meet 300V UL voltage requirements. IEC voltage ratings differ: 1757624 maintains 400V IEC (matching 1900002), while 1836502 operates at 320V IEC. For applications requiring 400V IEC operation, 1757624 is the appropriate selection. For applications operating at or below 320V IEC, 1836502 is acceptable.

Q: Are there mechanical compatibility issues with the shorter contact tail on 1836502?

A: Contact tail length on 1836502 is 2.00mm compared to 4.19mm on 1900002 and 4.60mm on 1757624. PCB through-hole depth and solder joint formation must be verified to ensure adequate mechanical and electrical connection. Shorter contact tails may require design review for specific applications.

Q: Do all three parts meet RoHS compliance requirements?

A: 1900002 is RoHS Compliant. 1757624 is ROHS3 Compliant. 1836502 RoHS status is not specified in available documentation. For applications with mandatory RoHS requirements, 1757624 provides confirmed ROHS3 compliance.

Q: What housing material differences exist between the substitutes?

A: 1900002 uses Polybutylene Terephthalate (PBT). 1757624 uses Polyamide (PA/Nylon). 1836502 uses Liquid Crystal Polymer (LCP). All three materials meet UL94 V-0 flammability requirements. Material selection may affect thermal performance, chemical resistance, and mechanical properties in specific operating environments.

Q: Are solder termination parts (1757624, 1836502) compatible with press-fit PCB designs?

A: No. Press-fit designs require dedicated press-fit holes with specific tolerances and depth. Solder termination parts require standard through-holes with solder pads. PCB redesign is necessary to accommodate solder termination substitutes.
