Phoenix Contact 1899870 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1899870 is a 5-position terminal block header with male pins, shrouded on 4 sides, featuring 0.197" (5.00mm) pitch and 90° right-angle through-hole mounting. This component is classified as obsolete, making identification of equivalent substitute parts essential for ongoing design support and procurement continuity. The part operates at 12A (IEC) / 15A (UL) and 400V (IEC) / 300V (UL), with press-fit termination and polybutylene terephthalate (PBT) housing.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1899870 is determined by the following critical parameters:

Primary Matching Criteria:

• Number of positions: 5
• 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
• Flammability rating: UL94 V-0

Secondary Considerations:

• Termination style (press-fit vs. solder) affects assembly compatibility
• Housing material variations (PBT, PA/Nylon, LCP) maintain electrical and mechanical performance within specified ratings
• Contact tail length variations accommodate different PCB design requirements
• Product status (active vs. obsolete) indicates availability and long-term support

The identified substitute parts (1757501 and 1836379) maintain all primary matching criteria while offering active product status and improved procurement availability.

Parameter Comparison

Engineering Selection Recommendations

Part 1757501 (COMBICON MSTBA Series): This substitute offers active product status with identical electrical ratings (12A IEC, 15A UL, 400V IEC, 300V UL) and mechanical compatibility. The primary design difference is termination style (solder vs. press-fit) and housing material (PA/Nylon vs. PBT). Both materials maintain UL94 V-0 flammability compliance. The contact tail length is 0.138" (4.60mm) compared to the original 0.165" (4.19mm), requiring PCB design verification for through-hole depth compatibility. ROHS3 compliance provides enhanced regulatory alignment.

Part 1836379 (COMBICON CCA Series): This substitute provides active product status with equivalent mechanical form factor and electrical performance. The UL current rating is 16A, exceeding the original 15A specification. Housing material is liquid crystal polymer (LCP), which maintains UL94 V-0 compliance. The contact tail length is significantly shorter at 0.079" (2.00mm), necessitating PCB design review for mounting compatibility. This part is suitable for applications where the shorter tail length accommodates board thickness and component density requirements.

Both substitutes maintain the critical parameters: 5 positions, 0.197" (5.00mm) pitch, 90° right-angle orientation, shrouded male pin configuration, and through-hole mounting. Selection between substitutes depends on termination method compatibility (solder vs. press-fit) and PCB design constraints related to contact tail length.

Frequently Asked Questions (FAQ)

Q: Can I directly replace the 1899870 with either substitute part?

A: Direct replacement requires verification of two factors: (1) termination method compatibility—the original part uses press-fit termination while both substitutes use solder termination, requiring assembly process adjustment; (2) contact tail length—the 1757501 has a shorter tail (0.138" vs. 0.165"), and the 1836379 has a significantly shorter tail (0.079"), which may affect PCB through-hole depth and mounting clearance. PCB design review is necessary before substitution.

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

A: All three parts meet or exceed the original electrical specifications. The 1899870 and 1757501 are rated identically at 12A (IEC) and 15A (UL). The 1836379 provides a higher UL current rating of 16A. Voltage ratings are equivalent across all parts at 400V (IEC) and 300V (UL), except the 1836379 does not specify an IEC voltage rating. All maintain UL94 V-0 flammability compliance.

Q: How do housing material differences affect performance?

A: The original 1899870 uses polybutylene terephthalate (PBT), while 1757501 uses polyamide (PA/Nylon) and 1836379 uses liquid crystal polymer (LCP). All three materials achieve UL94 V-0 flammability ratings and maintain the specified electrical and mechanical performance within the operating parameters. Material selection may influence thermal characteristics and chemical resistance in specific application environments, but all are suitable for standard terminal block applications.

Q: What is the significance of the contact tail length differences?

A: Contact tail length determines how deeply the component penetrates the PCB. The original 1899870 has a 0.165" (4.19mm) tail, 1757501 has 0.138" (4.60mm), and 1836379 has 0.079" (2.00mm). Shorter tails may be advantageous for thin PCBs or high-density layouts but require verification that the tail length is sufficient for reliable solder joint formation or press-fit engagement. PCB design specifications must be reviewed to ensure compatibility.

Q: Are there compliance or regulatory differences between these parts?

A: The 1899870 is RoHS Compliant. The 1757501 is ROHS3 Compliant, which represents an updated regulatory standard. The 1836379 is RoHS Compliant. All three parts carry EAR99 ECCN classification and 8536.69.4040 HTSUS code. The 1757501 includes REACH Unaffected status. For applications subject to specific regulatory requirements, compliance documentation should be verified with the manufacturer.

Q: Why is the original part obsolete, and what does this mean for long-term availability?

A: The 1899870 is classified as obsolete, indicating Phoenix Contact has discontinued active production and support. Both substitute parts (1757501 and 1836379) are active products with current inventory availability (1900 and 1183 units respectively), ensuring long-term procurement viability. Obsolete status does not affect the performance of existing installed components but necessitates design migration to active alternatives for new production.
