OSTVF205050 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The OSTVF205050 is a 20-position terminal block header manufactured by On Shore Technology Inc., designed for vertical through-hole mounting with 5.08mm 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 RoHS3 compliance and unlimited moisture sensitivity rating (MSL 1).

Alternative components may be required due to supply constraints, regional availability, or specific application requirements while maintaining electrical and mechanical compatibility.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTVF205050 is determined by strict equivalence across the following critical parameters:

• Position Configuration: 20 positions arranged as 10 per level across 2 levels
• Pitch Spacing: 0.200" (5.08mm) center-to-center distance
• Header Type: Male pins with dual-side shrouding
• Orientation: Vertical mounting
• Termination: Solder connection
• Mounting: Through-hole PCB mounting
• Voltage Rating: Minimum 300V (UL)
• Current Rating: Minimum 12A (UL) to 15A (UL)
• Compliance: RoHS3 and REACH requirements

The Phoenix Contact 1845565 meets all critical substitution criteria, maintaining identical position configuration, pitch, orientation, and termination method while satisfying voltage and current requirements within acceptable operating parameters.

Parameter Comparison

Engineering Selection Recommendations

Both the OSTVF205050 and 1845565 are active production components with full RoHS3 and REACH compliance. Selection between these parts should be based on:

OSTVF205050 (On Shore Technology Inc.): Primary choice when original specification compliance is required. Rated for 15A at 300V with thermoplastic housing and 3.90mm contact tail length.

1845565 (Phoenix Contact): Acceptable substitute when supply of the primary part is unavailable. Rated for 12A at 300V with PBT housing and 3.50mm contact tail length. Contact tail length difference of 0.40mm and housing material variation must be evaluated for specific PCB design and mechanical clearance requirements.

Both parts maintain identical electrical ratings at 300V, position configuration, pitch spacing, and flammability classification. The current rating difference (15A vs. 12A) is acceptable for applications operating below 12A continuous current.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1845565 be used as a direct replacement for the OSTVF205050?

A: Yes, for applications operating at or below 12A. Both parts share identical position configuration (20 positions, 10 per level), 5.08mm pitch, vertical orientation, and 300V rating. The contact tail length differs by 0.40mm, which must be verified against PCB hole depth specifications.

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

A: The OSTVF205050 has a 3.90mm contact tail, while the 1845565 has a 3.50mm contact tail. This 0.40mm difference affects solder joint depth and PCB hole design. Verify that your PCB accommodates the shorter tail length of the substitute part.

Q: Are there differences in housing material between these parts?

A: Yes. The OSTVF205050 uses thermoplastic housing, while the 1845565 uses polybutylene terephthalate (PBT). Both materials meet UL94 V-0 flammability requirements. PBT offers improved chemical and thermal resistance in certain environments.

Q: Do both parts meet the same compliance standards?

A: Yes. Both the OSTVF205050 and 1845565 are RoHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes. Both carry HTSUS code 8536.69.4040.

Q: What is the current rating difference, and does it matter?

A: The OSTVF205050 is rated for 15A (UL), while the 1845565 is rated for 12A (UL). For applications requiring continuous current above 12A, the original OSTVF205050 must be used. For applications at or below 12A, the substitute is acceptable.

Q: Are the insulation heights compatible?

A: Yes. The OSTVF205050 has an insulation height of 0.866" (22.00mm), and the 1845565 has 0.870" (22.10mm). This 0.004" difference is negligible for mechanical clearance in standard applications.
