OSTTS06115A Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The OSTTS06115A is a 6-position terminal block plug manufactured by On Shore Technology Inc., designed for free-hanging (in-line) applications with 0.138" (3.50mm) pitch spacing. This active product features female sockets with screw termination, supporting wire gauges from 16-28 AWG and operating across -30°C to 105°C. The component is ROHS3 compliant and rated for 300V UL voltage specifications.

Substitute parts become necessary when addressing inventory constraints, extended lead times, or specific application requirements such as enhanced temperature ranges, improved flammability ratings, or alternative contact materials that may better suit particular environmental or mechanical conditions.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the OSTTS06115A is determined by strict alignment with the following core parameters:

• Position Count & Pitch: Substitute parts must maintain 6 positions at 0.138" (3.50mm) pitch spacing to ensure mechanical and electrical compatibility with mating connectors.
• Socket Configuration: Female socket type is required for direct functional equivalence.
• Mounting Method: Free-hanging (in-line) orientation must be preserved.
• Voltage Rating: Minimum 300V UL rating is mandatory.
• Wire Gauge Compatibility: Substitute parts must accommodate the 16-28 AWG range or a superset thereof.
• Termination Method: Screw-based termination is the functional requirement; variations in screw mechanism (standard vs. rising cage clamp) are permissible provided electrical and mechanical performance remain equivalent.
• Regulatory Compliance: ROHS3 compliance is required; additional certifications (such as UL94 flammability ratings) represent enhancements rather than substitution barriers.

The Molex 0395033006 meets all substitution criteria through equivalent position count, pitch, socket type, mounting configuration, voltage rating, and regulatory status.

Parameter Comparison

Engineering Selection Recommendations

Both the OSTTS06115A and 0395033006 are active products with ROHS3 compliance and MSL-1 moisture sensitivity ratings, making either suitable for standard procurement workflows without special handling requirements.

The Molex 0395033006 provides an extended operating temperature range (-40°C to 115°C versus -30°C to 105°C) and supports wire gauges up to 30 AWG (compared to 28 AWG maximum for the On Shore part). The rising cage clamp termination mechanism in the Molex variant offers an alternative screw engagement method while maintaining functional equivalence. The Molex part also carries a UL94 V-0 flammability rating, providing enhanced material performance characteristics.

Selection between these parts should be based on application-specific requirements: choose the OSTTS06115A where existing inventory or established supply chains favor the On Shore product, or select the 0395033006 where extended temperature operation, broader wire gauge accommodation, or enhanced flammability certification align with system specifications.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0395033006 directly replace the OSTTS06115A in existing assemblies?

A: Yes. Both parts maintain identical 6-position configuration at 0.138" (3.50mm) pitch with female socket termination and free-hanging mounting. The rising cage clamp termination in the Molex variant is functionally equivalent to standard screw termination for electrical and mechanical performance.

Q: What is the significance of the extended temperature range in the Molex part?

A: The Molex 0395033006 operates from -40°C to 115°C, compared to -30°C to 105°C for the On Shore part. This extended range accommodates applications requiring operation in more extreme thermal environments. If your application operates within the OSTTS06115A temperature window, this difference is not a limiting factor.

Q: Does the wire gauge difference (28 AWG vs. 30 AWG maximum) affect substitution?

A: No. The Molex part accommodates 16-30 AWG, which is a superset of the OSTTS06115A range (16-28 AWG). Any wire gauge compatible with the original part is also compatible with the substitute.

Q: Are there packaging or inventory considerations?

A: Both parts are supplied in bulk packaging. Current inventory shows 1054 pcs for the OSTTS06115A and 3180 pcs for the Molex 0395033006. Availability should be verified with your supplier for lead time and quantity requirements.

Q: What does the UL94 V-0 rating on the Molex part indicate?

A: UL94 V-0 is a flammability classification indicating the housing material (polyamide/nylon 6/6) meets stringent flame-retardant requirements. This is an enhancement over the On Shore part and may be required for applications with specific safety certifications or regulatory mandates.

Q: Are both parts REACH compliant?

A: The OSTTS06115A is REACH Unaffected. The Molex 0395033006 is REACH Affected, meaning it contains substances of concern but remains compliant with REACH regulations. Verify REACH status requirements for your specific application or end market.
