Key Parameters

Substitute Part Grouping Explanation

Substitution of the OSTEH072160 is based on strict alignment of the following critical parameters:

• Position Count & Pitch: Both main and substitute parts must maintain 7 positions at 0.138" (3.50mm) pitch to ensure mechanical and electrical compatibility with mating unshrouded headers
• Termination Method: Screw-leaf spring with wire guard termination is required for functional equivalence
• Mounting Configuration: Free hanging (in-line) orientation must be preserved
• Wire Gauge Compatibility: 16-28 AWG acceptance range ensures compatibility with existing wiring harnesses
• Operating Temperature Range: -40°C to 115°C operational envelope must be maintained
• Flammability & Compliance: UL94 V-0 and ROHS3 compliance are mandatory for regulatory equivalence

The substitute part TH0721500000G meets all these criteria while offering enhanced electrical ratings and active product status.

Parameter Comparison

Engineering Selection Recommendations

The TH0721500000G from Amphenol Anytek is a direct functional equivalent to the obsolete OSTEH072160. Selection of this substitute is supported by:

• Mechanical Compatibility: Identical pitch, position count, and mounting configuration ensure direct replacement in existing connector systems
• Electrical Equivalence: The substitute meets or exceeds all electrical parameters of the original part, with higher voltage (300V vs. 150V) and specified current rating (10A) providing enhanced performance margin
• Regulatory Compliance: Both parts maintain UL94 V-0 flammability rating and ROHS3 compliance, ensuring continued adherence to applicable standards
• Active Product Status: The substitute part is classified as active, ensuring long-term availability and supply chain continuity compared to the obsolete original

Frequently Asked Questions (FAQ)

Q: Can TH0721500000G be used as a direct replacement for OSTEH072160 in existing assemblies?

A: Yes. Both parts share identical mechanical dimensions, pitch spacing, position count, and termination method. The substitute meets all functional requirements for direct substitution in applications originally designed for the OSTEH072160.

Q: What are the key differences between these parts?

A: The primary differences are product status (obsolete vs. active), contact material (brass vs. phosphor bronze), housing material (brass vs. thermoplastic), and electrical ratings. The TH0721500000G provides higher voltage rating (300V vs. 150V) and specified current capacity (10A), representing an enhancement over the original specification.

Q: Are there any compatibility concerns with wire gauge or termination?

A: No. Both parts accept 16-28 AWG wire and employ identical screw-leaf spring termination with wire guard. Wire strip length requirements are identical at 5-6mm.

Q: Does the substitute part maintain the same operating temperature range?

A: Yes. Both parts operate across -40°C to 115°C, ensuring thermal compatibility in equivalent applications.

Q: What is the significance of the different contact and housing materials?

A: The substitute uses phosphor bronze contacts and thermoplastic housing versus brass in both the original part. These material changes are within the scope of equivalent terminal block design and do not affect functional compatibility for the specified electrical and mechanical parameters.
