Engineering Selection Recommendations

The V71872500000G substitute part is suitable for applications currently using OSTV7187250 based on the following factors:

All critical electrical parameters are identical: 10 A current rating, 300 V voltage rating, and phosphor bronze contact material ensure equivalent electrical performance in circuit applications.

All mechanical parameters are identical: 18-position configuration, 5.00mm pitch, vertical orientation, and through-hole mounting ensure direct PCB compatibility without layout modifications.

Material specifications are identical: UL94 V-0 flammability rating and thermoplastic housing maintain equivalent safety and environmental performance.

Regulatory compliance is maintained: Both parts are ROHS3 compliant and REACH unaffected, satisfying current regulatory requirements.

The substitute part offers extended operating temperature range (-40°C to 115°C versus -30°C to 105°C), providing additional thermal margin for demanding applications.

The substitute part maintains active product status, ensuring long-term availability and supply chain continuity compared to the obsolete main part.

Frequently Asked Questions (FAQ)

Q: Can V71872500000G be used as a direct replacement for OSTV7187250 on existing PCBs?

A: Yes. Both parts share identical mechanical dimensions, pitch, position count, and mounting type. No PCB layout modifications are required.

Q: Are there electrical performance differences between these parts?

A: No. Both parts have identical current ratings (10 A), voltage ratings (300 V), and contact materials (phosphor bronze), ensuring equivalent electrical performance.

Q: What is the significance of the operating temperature difference?

A: The substitute part (V71872500000G) operates from -40°C to 115°C, compared to the main part's -30°C to 105°C range. This extended range provides additional thermal margin but does not affect compatibility in applications within the original temperature specification.

Q: Why is product status relevant for substitution?

A: OSTV7187250 is classified as obsolete, meaning it will not be manufactured or restocked. V71872500000G is active, ensuring continued availability for future production runs and maintenance applications.

Q: Are there packaging differences between these parts?

A: The main part is packaged as specified by the manufacturer, while the substitute is supplied in bulk packaging. Functional performance is identical; packaging affects only logistics and handling.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both parts are ROHS3 compliant and REACH unaffected, satisfying current regulatory requirements for electronic components.

Q: What is the contact mating finish difference?

A: The substitute part specifies tin contact mating finish, while the main part does not specify this parameter. This does not affect substitution compatibility.
