Substitute Part Grouping Explanation

Substitution eligibility is determined by the following critical parameters:

Number of Positions and Pitch: All substitute parts maintain 8 positions with pitch specifications of 0.200" (5.08mm) or 0.197" (5.00mm), ensuring mechanical and electrical compatibility with standard 5mm-class connector footprints.
Header Orientation and Type: All candidates feature 90° right-angle orientation with male pins and four-side shrouding, maintaining identical form factor and mounting interface.
Mounting and Termination: All parts support through-hole or solder mounting with compatible termination methods.
Electrical Ratings: Substitute parts meet or exceed the voltage requirements (300 V minimum UL rating) and current capacity (10 A minimum UL rating per position).
Flammability and Compliance: All substitute parts carry UL94 V-0 or equivalent flammability ratings and maintain RoHS3 compliance or better.

The three substitute parts are grouped as direct functional equivalents based on these parameters, with variations in housing material, contact material, and packaging that do not affect core electrical or mechanical performance.

Engineering Selection Recommendations

Phoenix Contact 1955099: Select this part for applications requiring LCP housing material, which offers superior dimensional stability and chemical resistance. The component maintains active product status with established supply chain support through Phoenix Contact distribution channels.

Würth Elektronik 691313510008: This substitute provides equivalent electrical performance with PBT housing and enhanced current capacity (20 A UL rating). Suitable for applications where higher current handling is beneficial. Maintains ROHS3 compliance and specified operating temperature range of -40°C to 105°C. Available in tray packaging.

Würth Elektronik 691313710008: This variant features a 0.197" (5.00mm) pitch specification, representing a minor deviation from the 0.200" (5.08mm) standard. The 0.005" (0.08mm) pitch difference may require PCB footprint verification before substitution. Offers 20 A UL current rating and ROHS3 compliance. Available in bulk packaging with highest inventory availability (1361 pcs).

On Shore Technology OSTOQ085451: This part maintains exact pitch specification (0.200" / 5.08mm) and tin contact finish. Operating temperature range extends to 115°C, supporting higher-temperature applications. ROHS3 compliant. Contact tail length (0.157" / 4.00mm) differs from the primary part. Highest inventory availability (2676 pcs) among all candidates.

Selection should prioritize pitch specification match (0.200" / 5.08mm preferred) and verify PCB footprint compatibility before implementation. All candidates meet minimum voltage and flammability requirements for standard industrial applications.

Frequently Asked Questions (FAQ)

Q: Can Würth Elektronik 691313710008 be used as a direct replacement for Phoenix Contact 1955099?

A: The 691313710008 features a 0.197" (5.00mm) pitch compared to the 0.200" (5.08mm) pitch of the 1955099. This 0.005" (0.08mm) difference requires PCB footprint verification. If the PCB is designed for 5.08mm spacing, this part may not align correctly. Confirm footprint compatibility before substitution.

Q: What is the primary difference between the two Würth Elektronik substitutes?

A: The 691313510008 maintains the 0.200" (5.08mm) pitch specification, while the 691313710008 uses 0.197" (5.00mm) pitch. Both offer identical electrical ratings (20 A UL, 300 V UL) and UL94 V-0 flammability. The pitch difference is the critical distinction for PCB compatibility.

Q: Are all substitute parts RoHS compliant?

A: Yes. Phoenix Contact 1955099 is RoHS Compliant. Würth Elektronik parts (691313510008 and 691313710008) are ROHS3 Compliant. On Shore Technology OSTOQ085451 is ROHS3 Compliant. All meet current RoHS requirements.

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

A: Contact tail length affects solder joint depth and PCB hole engagement. Phoenix Contact 1955099 has 0.102" (2.60mm) tail length, while substitutes range from 0.138" to 0.157" (4.60mm to 4.00mm). Longer tail lengths provide greater solder joint surface area. Verify PCB hole depth specifications to ensure adequate engagement.

Q: Which substitute offers the highest current capacity?

A: Both Würth Elektronik parts (691313510008 and 691313710008) offer 20 A UL current rating, compared to 10 A for the Phoenix Contact 1955099. This represents a 2x increase in current handling capability per position.

Q: What packaging options are available?

A: Phoenix Contact 1955099 is supplied in Tape & Reel (TR) packaging. Würth Elektronik 691313510008 is supplied in Tray packaging. Würth Elektronik 691313710008 and On Shore Technology OSTOQ085451 are supplied in Bulk packaging. Select based on assembly process requirements and inventory management practices.

Q: Is operating temperature range a critical substitution factor?

A: Operating temperature is specified for all substitute parts (-40°C to 105°C for Würth Elektronik; -40°C to 115°C for On Shore Technology) but not specified for the primary Phoenix Contact part. If the application operates within the specified ranges of the substitutes, compatibility is maintained. For applications exceeding 105°C, the On Shore Technology part supports operation to 115°C.
