OSTV7141150 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The OSTV7141150 is a 14-position terminal block header manufactured by On Shore Technology Inc., featuring female sockets with 0.138" (3.50mm) pitch spacing for vertical through-hole mounting. This component is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing system support and new design implementations.

Terminal block headers serve as connectors for wire termination in industrial control systems, power distribution, and signal routing applications. The obsolete status of the OSTV7141150 necessitates evaluation of active substitute components that maintain electrical and mechanical compatibility with existing designs.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the OSTV7141150 is determined by the following critical parameters:

Position Count & Configuration: Both the main part and substitute maintain 14 positions in a single-level, vertical orientation, ensuring mechanical fit within existing PCB layouts and connector housings.

Electrical Ratings: The substitute part meets or exceeds the UL current rating of 8 A and voltage rating of 300 V, maintaining electrical safety margins for the intended application.

Pitch Spacing: The OSTV7141150 operates at 0.138" (3.50mm) pitch. The substitute part (1875548) operates at 0.150" (3.81mm) pitch. This represents a pitch variation that requires mechanical evaluation for PCB footprint compatibility.

Mounting & Termination: Both components utilize through-hole solder termination, compatible with standard PCB assembly processes.

Compliance & Certifications: Both parts maintain UL94 V-0 flammability rating, ROHS3 compliance, and REACH unaffected status, ensuring regulatory alignment.

Contact Geometry: Identical contact tail length (0.134" / 3.40mm) and insulation height (0.571" / 14.50mm) support direct mechanical substitution when pitch spacing is accommodated.

Parameter Comparison

Engineering Selection Recommendations

The Phoenix Contact 1875548 is an active substitute for the obsolete OSTV7141150. Both components share identical electrical ratings (8 A UL, 300 V UL), mechanical mounting configuration (through-hole solder termination), and regulatory compliance (UL94 V-0, ROHS3, REACH unaffected).

The primary design consideration is pitch spacing: the OSTV7141150 operates at 0.138" (3.50mm) while the 1875548 operates at 0.150" (3.81mm). This 0.012" (0.31mm) pitch difference requires PCB footprint evaluation. Designs with fixed PCB hole patterns must accommodate this spacing variation through layout modification or alternative component selection.

The 1875548 provides additional IEC compliance data (8 A IEC, 320 V IEC) not specified for the original part, offering expanded regulatory documentation for international applications.

Frequently Asked Questions (FAQ)

Q: Can the 1875548 be used as a direct drop-in replacement for the OSTV7141150?

A: Electrical and thermal specifications are compatible. However, the pitch spacing difference (3.50mm vs. 3.81mm) requires PCB footprint verification. Direct substitution is possible only if the PCB layout accommodates the 0.012" spacing variation or if the component is mounted off-board.

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

A: Pitch spacing determines the center-to-center distance between contact positions. The 0.138" (3.50mm) OSTV7141150 and 0.150" (3.81mm) 1875548 have different hole patterns. Existing PCB designs must be evaluated for compatibility or redesigned to accommodate the substitute pitch.

Q: Are the electrical ratings equivalent between these parts?

A: Yes. Both components are rated for 8 A at 300 V under UL standards. The 1875548 additionally provides IEC ratings (8 A, 320 V), which exceed the UL specification.

Q: Do both parts meet the same regulatory standards?

A: Yes. Both the OSTV7141150 and 1875548 are UL94 V-0 rated, ROHS3 compliant, and REACH unaffected. They share identical ECCN (EAR99) and HTSUS (8536.69.4040) classifications.

Q: What is the difference in contact material specifications?

A: The OSTV7141150 specifies phosphor bronze contacts. The 1875548 does not provide contact material data in the available specifications. Contact material should be confirmed with the manufacturer if this parameter is critical for the application.

Q: Are the physical dimensions compatible?

A: Contact tail length (0.134" / 3.40mm) and insulation height (0.571" / 14.50mm) are identical, supporting mechanical compatibility. Pitch spacing remains the primary dimensional consideration for PCB integration.

Q: What is the inventory status of these parts?

A: The OSTV7141150 has 796 units in stock (obsolete status). The 1875548 has 751 units in stock (active status). The active status of the 1875548 ensures long-term availability for new designs and ongoing production support.
