OSTV7101150 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The OSTV7101150 is a 10-position vertical terminal block header manufactured by On Shore Technology Inc., designed for solder termination through-hole mounting applications. This component features female sockets with 0.138" (3.50mm) pitch spacing and operates within a temperature range of -30°C to 105°C. The part is classified as obsolete, making identification of functionally equivalent alternatives necessary for ongoing design support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTV7101150 is determined by the following critical parameters:

• Position Count: Must equal 10 positions
• Header Type: Must be female socket configuration
• Orientation: Must be vertical mounting
• Termination: Must support solder termination
• Mounting: Must be through-hole compatible
• Electrical Ratings: Current capacity minimum 8 A (UL), voltage minimum 300 V (UL)
• Compliance: Must maintain ROHS3 compliance and UL94 V-0 flammability rating

The Phoenix Contact 1875506 qualifies as a substitute based on these parameters. While the pitch differs (0.150" versus 0.138"), both components share identical position count, socket type, vertical orientation, solder termination, through-hole mounting, and equivalent electrical ratings. The pitch variation represents a mechanical accommodation that may require PCB layout adjustment but does not affect functional substitution eligibility within the specified parameter constraints.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1875506 serves as a direct functional substitute for the obsolete OSTV7101150. Both components maintain identical electrical performance specifications (8 A current, 300 V voltage), equivalent mechanical dimensions for contact engagement (0.134" tail length, 0.571" insulation height), and matching compliance certifications (ROHS3, UL94 V-0).

The primary design consideration is the pitch spacing difference: 0.138" (3.50mm) versus 0.150" (3.81mm). This 0.012" variance requires PCB footprint modification but does not affect electrical or thermal performance. The Phoenix Contact component's active product status ensures ongoing availability and supply chain continuity compared to the obsolete On Shore part.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1875506 be used as a direct drop-in replacement for the OSTV7101150?

A: Electrical and thermal performance are equivalent. PCB layout modification is required due to the 0.012" pitch spacing difference. The substitute maintains identical contact tail length and insulation height, ensuring compatible mating with corresponding connector plugs.

Q: Are there compliance or certification differences between these components?

A: Both components are ROHS3 compliant and carry UL94 V-0 flammability ratings. Electrical ratings (8 A UL, 300 V UL) are identical. No compliance barriers exist for substitution.

Q: What is the impact of the pitch spacing difference?

A: The pitch difference (0.138" to 0.150") affects only PCB hole pattern spacing. Connector mating compatibility depends on the corresponding plug component pitch specification. Verify plug compatibility before implementation.

Q: Is the Phoenix Contact part currently available?

A: The 1875506 maintains active product status with documented inventory availability, providing supply continuity for the obsolete OSTV7101150.

Q: Do the housing materials affect performance or compatibility?

A: The OSTV7101150 uses thermoplastic housing while the 1875506 uses polyamide (PA/nylon). Both materials meet UL94 V-0 requirements and provide equivalent mechanical and thermal performance within the specified operating range (-30°C to 105°C).
