OSTT7050151 Equivalent & Substitute Parts

Part Overview

The OSTT7050151 is a 5-position wire-to-board terminal block manufactured by On-Shore Technology, designed for 0.250" (6.35mm) pitch applications with a 45° mating angle. This component features screw-based rising cage clamp termination, rated for 30 A at 300 V, and supports wire gauges from 10-24 AWG. The part is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and procurement planning.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTT7050151 is determined by the following critical parameters:

• Position Count & Pitch: 5 positions at 0.250" (6.35mm) spacing (non-negotiable for PCB compatibility)
• Electrical Ratings: 30 A current and 300 V voltage minimum
• Wire Gauge Compatibility: Support for 10-24 AWG wire range
• Termination Method: Screw-based rising cage clamp mechanism
• Mounting Configuration: Through-hole PCB mounting
• Compliance: ROHS3 compliance and EAR99 classification

The substitute part T70503510000G meets these core requirements. While the mating angle differs (35° versus 45°), both angles represent standard board-mounted orientations within the terminal block category and do not prevent functional substitution when mechanical clearance is verified for the specific application.

Parameter Comparison

Engineering Selection Recommendations

The T70503510000G qualifies as a functional substitute for the OSTT7050151 based on matching electrical specifications, pitch, position count, and termination methodology. The substitute part carries active product status from Amphenol Anytek, ensuring ongoing availability and supply chain continuity compared to the obsolete OSTT7050151.

Both parts maintain ROHS3 compliance and EAR99 classification, satisfying regulatory requirements. The T70503510000G provides an extended operating temperature range (-40°C ~ 115°C versus -30°C ~ 105°C), which may offer additional thermal margin in certain applications.

The primary design consideration is the mating angle difference (35° versus 45°). This variation requires verification of mechanical clearance within the specific PCB layout and connector housing geometry. The screw thread specification differs (M3 versus M4.6) and torque specification is lower on the substitute (0.78 Nm versus 1.0 Nm), necessitating adjustment of assembly procedures and torque application protocols.

Frequently Asked Questions (FAQ)

Q: Can T70503510000G directly replace OSTT7050151 without PCB modification?

A: Electrical and functional compatibility is confirmed. However, the mating angle difference (35° versus 45°) requires verification of mechanical fit within the existing PCB footprint and connector cavity. Physical clearance validation is necessary before implementation.

Q: What is the impact of the different screw thread specifications (M3 versus M4.6)?

A: The screw thread difference requires use of the appropriate fastener for each part. Assembly procedures must specify the correct screw size and apply the rated torque (1.0 Nm for OSTT7050151; 0.78 Nm for T70503510000G) to ensure proper clamping force and electrical contact.

Q: Are both parts compliant with current regulatory standards?

A: Yes. Both OSTT7050151 and T70503510000G are ROHS3 compliant and classified as EAR99, meeting current regulatory requirements for electronic component procurement and export.

Q: Why is the OSTT7050151 listed as obsolete?

A: Obsolete status indicates the part is no longer manufactured by On-Shore Technology. The T70503510000G from Amphenol Anytek provides an active alternative with equivalent electrical performance and compliance certifications.

Q: Does the extended temperature range of T70503510000G affect compatibility?

A: The extended range (-40°C ~ 115°C for T70503510000G versus -30°C ~ 105°C for OSTT7050151) represents an enhancement. If the original application operates within the OSTT7050151 temperature limits, the substitute will perform equivalently. Applications requiring the extended range benefit from the substitute's broader thermal specification.
