Substitute Part Grouping Explanation

Substitution eligibility is determined by strict alignment with the following core parameters:

Number of Positions & Pitch: All substitute parts maintain 10 positions at 0.138" (4.60mm) pitch
Header Type & Orientation: All maintain male pins, shrouded (4 side) configuration in vertical orientation
Termination & Mounting: All use solder termination with through-hole mounting
Electrical Ratings: Substitute parts must meet or exceed IEC/UL voltage and current specifications
Flammability & Compliance: All substitute parts maintain UL94 V-0 rating and RoHS/REACH compliance status

Four active substitute parts meet these criteria across three manufacturers: Phoenix Contact 1843680, TE Connectivity 1-1776130-0, TE Connectivity 1-796694-0, and On Shore Technology OSTOQ101250.

Engineering Selection Recommendations

Phoenix Contact 1843680 is the primary substitute within the same manufacturer series (COMBICON MCV). It maintains identical mechanical and electrical specifications with equivalent 8A current rating and 300V voltage rating. The part is active and available in bulk packaging. Housing material differs (PBT vs. glass-filled polyamide), and ROHS3 compliance supersedes the original RoHS status. This substitute provides direct functional equivalence with improved supply continuity.

TE Connectivity 1-1776130-0 and 1-796694-0 are cross-manufacturer alternatives from the Buchanan and Termi-Blok series. Both support higher current ratings (11A vs. 8A) and specified operating temperature ranges (-40°C to 110°C), providing enhanced performance margins. Both maintain UL94 V-0 flammability rating and 300V voltage specification. Contact material differs (phosphor bronze and brass respectively). These parts are active with established supply channels.

On Shore Technology OSTOQ101250 meets core dimensional and electrical requirements with 300V rating and tin-plated contacts. However, this part carries incomplete specification data: flammability rating is not specified, current rating is not provided, and insulation height differs significantly (0.138" vs. 0.362"). This part is suitable only when dimensional constraints permit the reduced insulation height and when flammability certification is not a design requirement.

For applications requiring direct form-fit-function replacement with established compliance documentation, Phoenix Contact 1843680 is the recommended primary substitute. For applications benefiting from enhanced current capacity and temperature range, TE Connectivity alternatives provide superior performance margins.

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1937680 be directly replaced with 1843680?

A: Yes. Both parts maintain identical 10-position, 4.6mm pitch vertical solder-through-hole configuration. Electrical ratings (8A, 300V) are equivalent. The primary difference is housing material (PBT vs. glass-filled polyamide) and ROHS3 vs. RoHS compliance status. Mechanical and electrical compatibility is confirmed.

Q: What is the difference between the Phoenix Contact and TE Connectivity substitutes?

A: Phoenix Contact 1843680 provides direct specification equivalence within the same series. TE Connectivity parts (1-1776130-0 and 1-796694-0) offer higher current capacity (11A vs. 8A) and specified operating temperature ranges (-40°C to 110°C). All three maintain 300V rating and UL94 V-0 flammability. Selection depends on whether enhanced current capacity and temperature specification are required.

Q: Is the On Shore Technology OSTOQ101250 a suitable substitute?

A: OSTOQ101250 meets core dimensional and voltage requirements but carries incomplete specification data. Flammability rating and current rating are not specified. Insulation height is significantly reduced (0.138" vs. 0.362"), which may affect mechanical fit in existing designs. This part is suitable only when dimensional constraints permit the reduced height and when flammability certification is not required.

Q: What packaging options are available for substitutes?

A: Phoenix Contact 1843680 is available in bulk packaging. TE Connectivity 1-1776130-0 packaging is not specified. TE Connectivity 1-796694-0 is available in bulk packaging. On Shore Technology OSTOQ101250 is available in bulk packaging. Verify packaging requirements with your procurement process.

Q: Are all substitute parts RoHS compliant?

A: Yes. Phoenix Contact 1843680 is ROHS3 compliant. TE Connectivity 1-1776130-0 is RoHS compliant. TE Connectivity 1-796694-0 is ROHS3 compliant. On Shore Technology OSTOQ101250 is ROHS3 compliant. All parts meet RoHS requirements for new designs.

Q: What is the difference in contact material between substitutes?

A: Phoenix Contact 1843680 uses tin-plated contacts (material not specified). TE Connectivity 1-1776130-0 uses phosphor bronze contacts. TE Connectivity 1-796694-0 uses brass contacts. On Shore Technology OSTOQ101250 uses brass contacts. All maintain tin mating finish. Contact material differences do not affect electrical performance for standard applications.
