OSTVF087050 Equivalent & Substitute Parts

Part Overview

The OSTVF087050 is an 8-position terminal block header manufactured by On Shore Technology Inc., designed for vertical through-hole mounting with 5.00mm pitch spacing. This component features male pins with dual-side shrouding and is rated for 15A at 300V (UL). The part is currently active in production with 862 units in stock.

Terminal block headers are essential interconnection components in industrial control systems, power distribution boards, and modular electronic assemblies. Equivalent and substitute parts become necessary when managing supply chain continuity, accommodating design revisions, or optimizing procurement across multiple suppliers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTVF087050 is determined by the following critical parameters:

Position Configuration: The substitute must maintain 8 total positions arranged as 4 positions per level across 2 levels to ensure mechanical and electrical compatibility with mating connectors and PCB layouts.

Pitch Specification: The 0.197" (5.00mm) pitch is the primary dimensional constraint. The identified substitute (Phoenix Contact 1845507) operates at 0.200" (5.08mm) pitch, representing a 0.03mm variance. This minor pitch tolerance is within acceptable mechanical interchangeability for standard terminal block applications where connector engagement and contact alignment remain functionally equivalent.

Electrical Ratings: The OSTVF087050 is rated 15A at 300V (UL). The substitute is rated 12A at 300V (UL), representing a reduced current capacity. Substitution is valid only in applications where the actual circuit current does not exceed 12A.

Connector Type & Orientation: Both components are vertical through-hole headers with male pins and dual-side shrouding, ensuring mechanical compatibility with standard mating receptacles.

Compliance & Material Standards: Both parts meet UL94 V-0 flammability requirements, ROHS3 compliance, and MSL 1 moisture sensitivity specifications, confirming suitability for equivalent applications.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection (OSTVF087050): Use the On Shore Technology OSTVF087050 in applications requiring the full 15A current capacity at 300V. This part is active in production with established supply availability (862 units in stock) and meets all standard compliance requirements including ROHS3 and UL94 V-0.

Substitute Selection (1845507): The Phoenix Contact 1845507 is suitable as an equivalent substitute in applications where circuit current does not exceed 12A at 300V. Both parts maintain identical compliance certifications (ROHS3, UL94 V-0, MSL 1) and equivalent mechanical form factors. The 0.03mm pitch variance and minor differences in contact tail length (0.154" vs. 0.138") and insulation height (0.866" vs. 0.870") do not affect functional interchangeability in standard terminal block applications.

Selection between these parts should be based on application current requirements, supplier availability, and procurement lead times. Both parts are active products with confirmed inventory.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1845507 be used as a direct replacement for the OSTVF087050?

A: The 1845507 is mechanically and electrically compatible for applications where circuit current does not exceed 12A. The OSTVF087050 is rated for 15A, while the substitute is rated for 12A. Verify that your application current requirement falls within the 12A limit before substitution.

Q: What is the significance of the 0.03mm pitch difference between 5.00mm and 5.08mm?

A: Both pitch specifications fall within standard terminal block tolerance ranges and are mechanically interchangeable with mating connectors designed for 5.0mm nominal spacing. This variance does not affect connector engagement or contact alignment in typical applications.

Q: Are both parts compliant with current environmental and safety standards?

A: Yes. Both the OSTVF087050 and 1845507 are ROHS3 compliant, UL94 V-0 rated, and carry MSL 1 moisture sensitivity classification. Both meet the same environmental and flammability requirements.

Q: What are the differences in contact tail length and insulation height?

A: The OSTVF087050 has a contact tail length of 0.154" (3.90mm) and insulation height of 0.866" (22.00mm). The 1845507 has a contact tail length of 0.138" (4.60mm) and insulation height of 0.870" (22.10mm). These dimensional variations are within acceptable tolerances for through-hole PCB mounting and do not affect functional compatibility.

Q: Which part should I select for new designs?

A: For new designs, select based on your application's current requirement. If 15A capacity is needed, use the OSTVF087050. If 12A capacity is sufficient, either part is acceptable. Consider supplier availability and lead times in your procurement decision.

Q: Are there any packaging or inventory considerations?

A: Both parts are supplied in bulk packaging. The OSTVF087050 has 862 units in stock, while the 1845507 has 735 units in stock. Verify current inventory status with your supplier before finalizing procurement.
