Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTVF045251 is determined by the following critical parameters:

• Electrical Compatibility: Current and voltage ratings must meet or exceed UL specifications (15 A at 300 V minimum)
• Physical Compatibility: 4-position configuration, 5.08mm pitch, 90° right-angle orientation, and through-hole solder mounting are mandatory
• Mechanical Compatibility: Male pin header type with shrouded design to maintain PCB integration and mating interface consistency
• Regulatory Compliance: UL94 V-0 flammability rating and ROHS3 compliance required for equivalent substitution
• Environmental Ratings: Operating temperature range and moisture sensitivity level must support the intended application

The substitute part 1762062 (Phoenix Contact COMBICON MDSTB series) meets these core substitution criteria while offering enhanced electrical ratings under IEC standards and alternative housing material composition.

Parameter Comparison

Engineering Selection Recommendations

Both the OSTVF045251 and 1762062 are active production components with full ROHS3 compliance and UL94 V-0 flammability certification. The OSTVF045251 features 4-side shrouding with brass contacts and thermoplastic housing. The 1762062 provides 2-side shrouding with interlocking side features, polybutylene terephthalate (PBT) housing, and tin contact mating finish. Both components satisfy UL electrical requirements at 15 A and 300 V. The 1762062 additionally meets IEC standards at 10 A and 400 V, providing broader international compliance. Selection between these parts should be based on specific PCB layout requirements, shrouding configuration needs, and housing material compatibility with the target application environment.

Frequently Asked Questions (FAQ)

Q: Can the 1762062 directly replace the OSTVF045251 on existing PCB designs?

A: Direct replacement is mechanically and electrically feasible due to identical pitch (5.08mm), position count (4), orientation (90° right angle), and through-hole solder mounting. However, the 1762062 features 2-side shrouding versus the OSTVF045251's 4-side shrouding, which may affect PCB layout clearances and mating interface geometry. Verify PCB footprint compatibility and connector mating requirements before implementation.

Q: What are the key differences in housing materials?

A: The OSTVF045251 uses thermoplastic housing, while the 1762062 uses polybutylene terephthalate (PBT). Both materials meet UL94 V-0 flammability requirements. PBT offers enhanced chemical resistance and dimensional stability at elevated temperatures, making it suitable for harsh industrial environments.

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

A: Yes. Both components are rated for 15 A at 300 V under UL standards. The 1762062 provides additional IEC certification at 10 A and 400 V, enabling use in international applications requiring IEC compliance.

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

A: The OSTVF045251 has a contact tail length of 0.157" (4.00mm), while the 1762062 measures 0.126" (3.20mm). This difference affects solder joint depth and PCB hole engagement. Verify PCB through-hole depth specifications to ensure adequate solder connection quality with either component.

Q: Do both parts have identical moisture sensitivity levels?

A: Yes. Both the OSTVF045251 and 1762062 are rated MSL 1 (Unlimited), indicating no moisture sensitivity restrictions for storage, handling, or reflow processes.
