Phoenix Contact 1707489 Terminal Block Header - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1707489 is an 8-position vertical terminal block header with 0.150" (3.81mm) pitch, designed for through-hole solder mounting. This component is part of the COMBICON MCV series and is actively manufactured. The part operates at 8A (IEC) / 8A (UL) and 250V (IEC) / 300V (UL), with a shrouded 4-side design for enhanced mechanical stability. Equivalent substitute parts are necessary when the primary part is unavailable, when supply chain optimization is required, or when design flexibility permits component standardization across multiple manufacturers.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1707489 is determined by strict alignment with the following core parameters:

• Position Count & Pitch: All substitutes must have exactly 8 positions at 0.150" (3.81mm) pitch
• Connector Type: Header configuration with male pins and 4-side shrouding
• Mounting Method: Through-hole solder termination
• Electrical Performance: Minimum UL rating of 8A at 300V
• Compliance: ROHS3 compliance and UL94 V-0 flammability rating
• Moisture Sensitivity: MSL 1 (Unlimited)

The four substitute parts listed below meet these core substitution criteria. Variations in contact material, housing material, and operating temperature ranges do not preclude substitution when the primary electrical and mechanical parameters align.

Parameter Comparison

Engineering Selection Recommendations

All four substitute parts are actively manufactured and ROHS3 compliant. Selection among these equivalents should be based on the following factors:

Molex 0395116008: Matches the primary part's 8A current rating and 300V voltage specification. Operating temperature range of -40°C to 105°C provides adequate thermal performance for standard industrial applications. REACH status is vendor-defined, requiring verification for regulated markets.

TE Connectivity 284517-8: Provides elevated current capacity at 11A, exceeding the primary part's 8A specification. Operating temperature extends to 110°C, offering enhanced thermal margin. REACH Unaffected status confirms regulatory compliance. This part is suitable for applications requiring higher current headroom.

Amphenol Anytek OQ0832500000G: Rated at 10A, providing intermediate current capacity between the primary part and TE Connectivity option. Operating temperature range of -40°C to 115°C offers the highest thermal rating among all options. Contact tail length of 0.138" (4.60mm) differs from the primary part's 0.102" (2.60mm), requiring PCB layout verification.

On Shore Technology OSTOQ083250: Provides functional equivalence with 300V rating and tin-plated contacts. Operating temperature range of -30°C to 105°C is narrower than other substitutes. Material flammability rating is not specified in available documentation. This part is suitable for cost-optimized applications where thermal and compliance margins are less critical.

Frequently Asked Questions (FAQ)

Q: Can these substitute parts be used interchangeably with the Phoenix Contact 1707489 on existing PCBs?

A: Yes, provided that the PCB layout accommodates the mechanical dimensions of the substitute part. The Amphenol Anytek OQ0832500000G has a different contact tail length (0.138" vs. 0.102"), which may require PCB pad adjustment. All other substitutes maintain compatible through-hole mounting geometry.

Q: What is the primary difference between these substitute parts?

A: The core electrical and mechanical specifications are equivalent across all substitutes. Differences exist in contact material composition (Brass, Phosphor Bronze, Copper Alloy), housing material (LCP, PA66, Thermoplastic Resin), and operating temperature ranges. These variations do not affect functional interchangeability for standard 8-position, 3.81mm pitch terminal block applications.

Q: Are all substitute parts ROHS3 compliant?

A: Yes, all four substitute parts carry ROHS3 compliance certification. The Molex 0395116008 has vendor-undefined REACH status; the remaining three parts are REACH Unaffected.

Q: Which substitute part offers the best thermal performance?

A: The Amphenol Anytek OQ0832500000G operates across the widest temperature range (-40°C to 115°C), followed by TE Connectivity 284517-8 (-40°C to 110°C). The Phoenix Contact primary part and Molex substitute both operate to 105°C maximum.

Q: Can I use the TE Connectivity 284517-8 in a circuit designed for 8A operation?

A: Yes. The TE Connectivity part is rated at 11A, which exceeds the circuit requirement of 8A. This provides additional current margin and does not create compatibility issues.

Q: What is the MSL rating for these parts, and why does it matter?

A: All parts carry MSL 1 (Unlimited) rating, indicating unlimited shelf life without moisture absorption concerns. This simplifies inventory management and eliminates bake-out requirements prior to assembly.
