OSTVK045150 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The OSTVK045150 is a 4-position terminal block header manufactured by On Shore Technology Inc., designed for through-hole solder mounting applications. This component features male pins with 4-side shrouding, a 0.200" (5.08mm) pitch, and 45° orientation. The part is Active in product status and fully compliant with RoHS3 and REACH regulations. Alternative equivalent parts may be required due to inventory constraints, manufacturing discontinuation, or specific application requirements for alternative mounting or termination methods.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTVK045150 is determined by the following critical parameters:

• Number of Positions: Must be 4
• Pitch: Must be 0.200" (5.08mm) or 0.197" (5.00mm) — minor pitch variations within 0.003" are functionally compatible
• Header Orientation: Must be 45°
• Type: Must be Header with Male Pins and Shrouded (4 Side) configuration
• Voltage Rating: Must meet or exceed 300 V UL specification
• Current Rating: Must meet or exceed 15 A UL specification
• Operating Temperature Range: Must encompass -30°C ~ 105°C
• Compliance: Must be RoHS3 Compliant and REACH Unaffected

The substitute parts listed below meet these core electrical and mechanical requirements, though secondary parameters such as contact material, housing material, and contact tail length may vary within acceptable engineering tolerances.

Parameter Comparison

Engineering Selection Recommendations

EDSTLZ990/4 (On Shore Technology Inc.): This substitute maintains identical pitch, position count, orientation, and operating temperature range as the primary part. Both components are manufactured by On Shore Technology Inc. and carry ROHS3 compliance. The primary distinction is the mounting type designation; however, both parts are solder-terminated through-hole components. This substitute is suitable for direct replacement in applications where On Shore Technology components are preferred.

1769829 (Phoenix Contact COMBICON SMSTBA series): This substitute meets all critical electrical parameters including 300 V UL voltage rating, 15 A UL current rating, and UL94 V-0 flammability rating. The pitch variance of 0.003" (5.00mm vs. 5.08mm) falls within acceptable mechanical tolerance for standard PCB layouts. The contact tail length is 0.023" (0.60mm) shorter than the primary part; this dimension must be evaluated against specific PCB design requirements. This substitute is suitable for applications requiring Phoenix Contact components or where the minor pitch variation is acceptable.

All substitute parts maintain Active product status and full RoHS3/REACH compliance, ensuring regulatory alignment with the original specification.

Frequently Asked Questions (FAQ)

Q: Can EDSTLZ990/4 be used as a direct replacement for OSTVK045150?

A: Yes. Both parts share identical pitch (0.200"/5.08mm), position count (4), orientation (45°), and operating temperature range (-30°C ~ 105°C). Both are manufactured by On Shore Technology Inc. and are RoHS3 compliant. The components are functionally equivalent for solder-through-hole mounting applications.

Q: What is the significance of the 0.003" pitch difference between OSTVK045150 and 1769829?

A: The OSTVK045150 has a 0.200" (5.08mm) pitch, while the 1769829 has a 0.197" (5.00mm) pitch. This 0.003" difference is within standard PCB design tolerances and does not affect electrical performance. PCB layout compatibility must be verified for the specific application.

Q: Does the 0.023" difference in contact tail length between OSTVK045150 and 1769829 affect compatibility?

A: Contact tail length affects solder joint depth and PCB hole engagement. The OSTVK045150 has a 0.161" (4.10mm) tail, while the 1769829 has a 0.138" (3.50mm) tail. This difference must be evaluated against PCB design specifications, particularly for through-hole depth and solder fillet requirements. Consult PCB design documentation before substitution.

Q: Are all three parts rated for 15 A at 300 V?

A: The OSTVK045150 and 1769829 are both rated 15 A at 300 V UL. The EDSTLZ990/4 is rated 300 V UL; current rating data is not provided in the specification. Verify current rating requirements for the specific application before selecting EDSTLZ990/4.

Q: What compliance certifications apply to all substitute parts?

A: All three parts are RoHS3 Compliant and REACH Unaffected. The OSTVK045150 and 1769829 carry UL94 V-0 flammability ratings. Compliance documentation should be reviewed for specific regulatory requirements.

Q: Can these parts be used interchangeably in the same PCB design?

A: Mechanical compatibility requires verification of pitch tolerance, contact tail length, and insulation height against PCB specifications. Electrical compatibility is confirmed across all three parts for the stated voltage and current parameters. Physical layout validation is necessary before implementing any substitution.
