Molex 0395272007 Terminal Block Plug - Equivalent & Substitute Parts

Part Overview

The Molex 0395272007 is a 7-position terminal block plug from the Eurostyle ESE 39527 series, designed for free-hanging in-line applications with 5.00mm pitch spacing. This component features female sockets with screw-rising cage clamp termination, rated for 10A at 300V (UL), and operates across -40°C to 105°C. The part is currently active in production with 957 units in stock. Equivalent and substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when system design requires compatibility with different connector families.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Molex 0395272007 is determined by the following critical parameters:

• Position Count: Must be 7 positions
• Pitch Tolerance: Acceptable range is 0.197" to 0.200" (5.00mm to 5.08mm) to maintain mechanical and electrical compatibility with mating headers
• Connector Configuration: Must be plug type with female sockets
• Wire Entry: 270° orientation required for in-line free-hanging installation
• Termination Method: Screw-rising cage clamp termination
• Current & Voltage: Minimum 10A at 300V (UL) to meet or exceed original specifications
• Wire Gauge Compatibility: Must accommodate 12-26 AWG minimum range
• Regulatory Compliance: ROHS3 compliance required; UL94 V-0 flammability rating required

The Phoenix Contact 1834958 qualifies as a substitute based on these parameters. While pitch differs slightly (5.08mm vs. 5.00mm), this variance falls within acceptable mechanical tolerance for terminal block applications and does not compromise mating with standard 5mm-pitch headers. The substitute exceeds current and voltage ratings and maintains all required certifications and termination characteristics.

Parameter Comparison

Engineering Selection Recommendations

Both the Molex 0395272007 and Phoenix Contact 1834958 are active production components with ROHS3 compliance and UL94 V-0 flammability certification. Selection between these parts should be based on:

Molex 0395272007 is the primary choice when:

• Exact 5.00mm pitch specification is required by system design
• Molex connector ecosystem integration is preferred
• Operating temperature range of -40°C to 105°C is a documented requirement

Phoenix Contact 1834958 is suitable when:

• The 5.08mm pitch variance is acceptable within system mechanical tolerances
• Higher current capacity (15A vs. 10A) provides additional design margin
• Extended wire gauge compatibility (12-30 AWG vs. 12-26 AWG) is beneficial
• Phoenix Contact connector family integration is preferred
• Inventory availability of the Molex part is constrained

Both parts maintain identical termination methodology, mounting configuration, voltage rating, and regulatory compliance status. The pitch difference of 0.08mm (0.003") is within standard mechanical tolerance for terminal block applications and does not compromise electrical performance or mating reliability with standard 5mm-pitch headers.

Frequently Asked Questions (FAQ)

Q: Can the Phoenix Contact 1834958 directly replace the Molex 0395272007 in existing assemblies?

A: Yes, with mechanical tolerance verification. The 0.08mm pitch difference (5.00mm vs. 5.08mm) is within acceptable tolerance for terminal block mating. However, verify that the mating header or socket accommodates this variance. Both parts use identical M3 screw termination and 270° wire entry orientation.

Q: What is the significance of the pitch difference between these parts?

A: Pitch is the center-to-center distance between adjacent contact positions. The 5.00mm and 5.08mm pitches are both standard in industrial terminal block applications. The 0.08mm difference is negligible for mechanical fit with standard headers but should be confirmed in applications with tight mechanical tolerances or custom-designed mating connectors.

Q: Are the current and voltage ratings interchangeable?

A: The Phoenix Contact 1834958 exceeds the Molex 0395272007 in current capacity (15A vs. 10A) while maintaining the same 300V UL voltage rating. The substitute can be used in applications rated for 10A without derating. If the application requires the full 15A capacity, the substitute provides additional margin.

Q: Do both parts support the same wire gauge range?

A: The Molex part supports 12-26 AWG, while the Phoenix Contact part supports 12-30 AWG. Both accommodate the original 12-26 AWG range. The Phoenix Contact part's extended range to 30 AWG provides flexibility for finer gauge wiring if needed.

Q: What are the packaging and inventory considerations?

A: Both parts are supplied in bulk packaging. The Molex 0395272007 has 957 units in stock, while the Phoenix Contact 1834958 has 870 units available. Lead times and availability should be confirmed with the supplier for production planning.

Q: Are there any thermal or environmental differences between these parts?

A: The Molex 0395272007 specifies an operating temperature range of -40°C to 105°C. The Phoenix Contact 1834958 does not provide a published operating temperature range in the available data. Both parts are rated for MSL 1 (Unlimited moisture sensitivity level) and maintain UL94 V-0 flammability compliance across their operating conditions.

Q: Can these parts be mixed in the same system?

A: Yes, both parts can coexist in a system if they are mated to separate headers or sockets designed for their respective pitch specifications. However, mixing them on the same header is not recommended due to pitch incompatibility. Maintain consistent part selection per connector location to avoid assembly errors.
