1923830 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1923830 is a 10-position terminal block header with male pins, shrouded on four sides, designed for 90° right-angle through-hole mounting. This component operates at 16A (IEC) / 16A (UL) and 400V (IEC) / 300V (UL), utilizing a 0.197" (5.00mm) pitch configuration. The part is actively produced and maintains RoHS compliance with UL94 V-0 flammability rating. Equivalent and substitute parts are identified to support procurement flexibility, inventory management, and supply chain continuity.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1923830 is determined by the following critical parameters:

• Position Count: 10 positions (fixed requirement)
• Pitch Tolerance: 0.197" (5.00mm) nominal, with 0.200" (5.08mm) acceptable within standard manufacturing tolerances for terminal block headers
• Header Type: Male pins, shrouded (4 side) configuration
• Orientation: 90° right-angle mounting
• Electrical Performance: Minimum 16A current capacity and 300V voltage rating (UL standard)
• Termination: Solder-compatible through-hole or solder mounting
• Compliance: RoHS compliance and tin contact finish

The On-Shore Technology OSTOQ105451 qualifies as a substitute based on matching position count, shrouded male pin configuration, 90° orientation, and electrical ratings. The pitch variance (5.08mm vs. 5.00mm) falls within acceptable tolerance for terminal block header applications. Both parts maintain RoHS compliance and tin contact finish specifications.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1923830 is the primary specification for applications requiring the exact COMBICON MSTBA series configuration with 0.197" (5.00mm) pitch and 0.339" (8.61mm) insulation height. This part maintains active production status and full RoHS compliance with UL94 V-0 flammability rating.

On-Shore Technology OSTOQ105451 serves as a functional substitute where pitch tolerance of ±0.003" (0.08mm) is acceptable and where the reduced insulation height (0.157" vs. 0.339") does not conflict with PCB layout constraints. This substitute maintains ROHS3 compliance and 300V UL voltage rating. The contact tail length difference (0.157" vs. 0.138") requires verification against solder pad depth specifications.

Both parts are actively produced with confirmed inventory availability. Selection between these parts should be based on mechanical fit requirements, PCB design specifications, and supply chain considerations rather than electrical performance, as both meet the stated current and voltage requirements.

Frequently Asked Questions (FAQ)

Q: Can OSTOQ105451 directly replace 1923830 on existing PCBs?

A: Direct replacement requires verification of three mechanical parameters: pitch tolerance acceptance (5.08mm vs. 5.00mm), insulation height clearance (0.157" vs. 0.339"), and contact tail length compatibility (0.157" vs. 0.138"). PCB pad spacing and solder depth must accommodate these differences.

Q: What is the pitch tolerance significance between 5.00mm and 5.08mm?

A: The 0.08mm difference represents approximately 1.6% variance. For 10-position headers, cumulative tolerance across all positions is 0.8mm. This falls within standard terminal block manufacturing tolerances but requires mating connector compatibility verification.

Q: Are both parts suitable for the same voltage and current applications?

A: Both parts support 300V UL rating. The Phoenix Contact 1923830 specifies 16A (IEC and UL). The On-Shore Technology OSTOQ105451 does not specify IEC current rating; UL current rating is not provided. Applications requiring 16A operation should reference the Phoenix Contact part or obtain explicit current rating confirmation from On-Shore Technology.

Q: What compliance differences exist between these parts?

A: Phoenix Contact 1923830 is RoHS Compliant. On-Shore Technology OSTOQ105451 is ROHS3 Compliant and REACH Unaffected. Both meet current regulatory requirements; ROHS3 represents the updated directive version.

Q: How do the insulation heights affect component selection?

A: Insulation height determines clearance above the PCB surface. The Phoenix Contact part (0.339") provides greater clearance for component density and thermal management. The On-Shore Technology part (0.157") requires tighter PCB layout coordination but may be suitable for space-constrained applications.
