Substitute Part Grouping Explanation

Substitution eligibility for the OSTVF045150 is determined by strict equivalence across the following critical parameters:

Position Configuration: 4 positions arranged as 2 positions per level across 2 levels
Pitch Spacing: 0.200" (5.08mm) center-to-center distance
Header Type: Male pins with 4-side shrouding
Orientation: Vertical mounting
Termination: Solder connection to PCB
Mounting: Through-hole technology
Electrical Performance: Current and voltage ratings must meet or exceed UL specifications (10A minimum, 300V minimum)
Compliance: RoHS3 compliance and UL94 V-0 flammability rating required

The Phoenix Contact 1845332 meets all substitution criteria through identical mechanical configuration, compatible electrical ratings, and equivalent regulatory compliance.

Engineering Selection Recommendations

The Phoenix Contact 1845332 is a direct substitute for the OSTVF045150 based on the following engineering criteria:

Mechanical Compatibility: Both components share identical position configuration (4 positions, 2×2 arrangement), pitch spacing (5.08mm), and through-hole mounting footprint. The insulation height variance of 0.004" (0.10mm) is within typical manufacturing tolerances and does not affect PCB layout or mechanical assembly.

Electrical Performance: The Phoenix Contact substitute meets or exceeds all UL electrical ratings. The 12A UL current rating provides additional margin over the 10A requirement. IEC ratings are additionally specified for the substitute, providing expanded compliance documentation for international applications.

Regulatory Compliance: Both components maintain ROHS3 compliance, UL94 V-0 flammability certification, and REACH unaffected status. Identical ECCN and HTSUS classifications confirm equivalent trade and export compliance.

Product Status: Both components are active in production with confirmed inventory availability, ensuring long-term supply continuity.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1845332 be used as a direct replacement on existing PCBs designed for the OSTVF045150?

A: Yes. The mechanical footprint, pitch spacing, contact tail length, and mounting type are identical. The 0.004" insulation height difference is within standard manufacturing tolerances and does not affect PCB layout compatibility.

Q: What is the difference in current rating between these components?

A: The OSTVF045150 is rated for 10A (UL), while the Phoenix Contact 1845332 is rated for 12A (UL). The substitute provides additional current capacity, making it suitable for applications requiring the original 10A specification.

Q: Are both components RoHS compliant?

A: Yes. Both the OSTVF045150 and Phoenix Contact 1845332 are ROHS3 compliant and REACH unaffected, meeting current environmental and regulatory requirements.

Q: Does the housing material difference affect substitution?

A: The OSTVF045150 uses thermoplastic housing, while the Phoenix Contact 1845332 uses polybutylene terephthalate (PBT). Both materials achieve UL94 V-0 flammability rating and are suitable for the same operating temperature range (-40°C to 115°C). PBT provides enhanced chemical and thermal resistance.

Q: What is the moisture sensitivity level for these components?

A: Both components have an MSL rating of 1 (Unlimited), indicating no moisture sensitivity restrictions during storage or handling.

Q: Are the contact materials compatible?

A: The OSTVF045150 specifies copper contacts with tin mating finish. The Phoenix Contact 1845332 specifies tin mating finish with contact material not detailed in the provided specifications. Both use tin finish for solder compatibility and corrosion resistance.

Q: Can these components be used in international applications?

A: Yes. Both components are REACH unaffected and carry EAR99 ECCN classification. The Phoenix Contact substitute additionally provides IEC electrical ratings (10A at 400V), supporting compliance documentation for international markets.
