Substitute Part Grouping Explanation

Substitution of the OSTV708A151 is determined by strict equivalence across the following critical parameters:

Electrical Compatibility: Current rating (10 A UL), voltage rating (300 V UL), and contact material (phosphor bronze) must match exactly
Mechanical Compatibility: 8 positions, 0.295" (7.50mm) pitch, 90° right-angle orientation, and through-hole solder termination must be identical
Physical Dimensions: Contact tail length (0.138" / 3.50mm) and insulation height specifications must accommodate existing PCB layouts
Regulatory Compliance: RoHS3 compliance and UL94 V-0 flammability rating are mandatory for equivalent substitution
Product Status: Active status preferred for long-term supply chain reliability

The substitute part V708A1510000G from Amphenol Anytek meets all critical electrical and mechanical parameters while offering active product status and extended operating temperature range.

Engineering Selection Recommendations

The V708A1510000G from Amphenol Anytek is a direct functional equivalent to the obsolete OSTV708A151. Both components maintain identical electrical ratings (10 A, 300 V), mechanical configuration (8 positions, 7.50mm pitch, 90° right angle), and regulatory compliance (RoHS3, UL94 V-0). The substitute part offers the additional advantage of active product status, ensuring continued availability and supply chain stability.

The V708A1510000G provides an extended operating temperature range (-40°C ~ 115°C versus -30°C ~ 105°C), which represents a performance enhancement suitable for applications requiring broader thermal operating conditions. Both components are MSL 1 rated and maintain identical contact material and housing specifications.

For applications where the original OSTV708A151 was specified, the V708A1510000G can be substituted without design modification or PCB layout changes, provided that the extended temperature capability does not introduce thermal management concerns in the target application.

Frequently Asked Questions (FAQ)

Q: Can V708A1510000G be used as a direct replacement for OSTV708A151 on existing PCBs?

A: Yes. Both components share identical pitch (7.50mm), position count (8), orientation (90° right angle), and contact tail length (3.50mm). No PCB layout modifications are required for substitution.

Q: What is the primary reason for substituting OSTV708A151?

A: The OSTV708A151 is listed as obsolete. The V708A1510000G maintains active product status, ensuring long-term supply availability and manufacturing continuity.

Q: Are the electrical ratings identical between these components?

A: Yes. Both components are rated for 10 A at 300 V per UL specifications, with phosphor bronze contacts and UL94 V-0 flammability rating.

Q: Does the extended operating temperature range of V708A1510000G affect compatibility?

A: No. The extended range (-40°C ~ 115°C versus -30°C ~ 105°C) represents a performance enhancement. Applications operating within the original temperature specification remain fully compatible.

Q: Are both components RoHS3 compliant?

A: Yes. Both OSTV708A151 and V708A1510000G are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity rating.

Q: What is the packaging difference between these parts?

A: OSTV708A151 packaging is not specified in available documentation. V708A1510000G is supplied in bulk packaging. Confirm packaging requirements with your procurement specification.
