Phoenix Contact 1730670 Terminal Block - Equivalent & Substitute Parts

Part Overview

The Phoenix Contact 1730670 is an 8-position wire-to-board terminal block with 0.200" (5.08mm) pitch, designed for horizontal mounting through PCB holes. This component belongs to the COMBICON EMKDS series and features screw-type rising cage clamp termination for secure wire connections. The part is currently obsolete, making identification of suitable substitute components essential for ongoing maintenance, repair, and new design implementations where legacy compatibility is required.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Phoenix Contact 1730670 is determined by strict alignment with the following core parameters:

• Position count and pitch: Must be 8 positions at 0.200" (5.08mm) spacing
• Mounting configuration: Horizontal orientation with through-hole PCB mounting
• Electrical ratings: Minimum 10 A current and 300 V voltage capability
• Wire termination method: Screw-type rising cage clamp mechanism
• Screw specification: M3 thread size
• Wire gauge compatibility: Support for 12-30 AWG conductors

Two substitute parts meet these criteria:

Phoenix Contact 1730450 (COMBICON MKDS series) - Direct functional equivalent with identical electrical and mechanical specifications. Active product status with improved compliance documentation.

TE Connectivity 282857-8 (Buchanan series) - Functionally compatible with enhanced current rating (24 A) and upgraded material specifications including tin-plated brass contacts and nickel-plated clamp components.

Parameter Comparison

Engineering Selection Recommendations

Phoenix Contact 1730450 is the primary substitute for direct replacement applications. This part maintains identical electrical and mechanical specifications while offering active product status and ROHS3 compliance certification. The COMBICON MKDS series provides continuity with the original EMKDS design philosophy and is recommended for applications requiring minimal design modification.

TE Connectivity 282857-8 is suitable for applications where enhanced current capacity (24 A versus 10 A) provides design margin or future-proofs the assembly. The Buchanan series features upgraded contact and clamp plating (tin-plated brass contacts, nickel-plated clamp and screw components) and PA66 housing material, offering improved durability and environmental resistance. This part is appropriate for new designs or upgrades where the higher current rating and material specifications align with system requirements.

Both substitutes maintain full compatibility with 12-30 AWG wire gauges, M3 screw termination, and 300 V voltage rating. Selection between them depends on whether the application requires exact electrical specification matching (1730450) or benefits from enhanced current capacity and material specifications (282857-8).

Frequently Asked Questions (FAQ)

Q: Can Phoenix Contact 1730450 be used as a direct replacement for 1730670?

A: Yes. The 1730450 maintains identical position count (8), pitch (5.08mm), current rating (10 A), voltage rating (300 V), wire gauge support (12-30 AWG), mounting type (through-hole), and termination method (M3 screw rising cage clamp). The primary difference is product status (active versus obsolete) and compliance certification level (ROHS3 versus RoHS).

Q: What is the key difference between Phoenix Contact 1730450 and TE Connectivity 282857-8?

A: The primary electrical difference is current rating: 282857-8 is rated for 24 A compared to 10 A for both Phoenix Contact parts. Material specifications also differ: 282857-8 features tin-plated brass contacts and nickel-plated clamp/screw components versus unspecified plating on the Phoenix Contact parts. Housing material is PA66 (Nylon 6/6) for 282857-8 versus PA (Nylon) for Phoenix Contact parts. All three maintain identical pitch, position count, voltage rating, and wire gauge compatibility.

Q: Are there packaging differences between these substitutes?

A: Phoenix Contact 1730670 packaging is listed as unspecified. Phoenix Contact 1730450 is supplied in bulk packaging. TE Connectivity 282857-8 is also supplied in bulk packaging. Packaging format should be confirmed with the supplier for procurement purposes.

Q: Which substitute should be selected for a new design?

A: For new designs, TE Connectivity 282857-8 is recommended if the application can accommodate the higher current rating (24 A) and does not require specific Phoenix Contact series compatibility. The enhanced material specifications (tin-plated contacts, nickel-plated components, PA66 housing) provide improved performance margins. Phoenix Contact 1730450 is appropriate if Phoenix Contact series continuity or exact 10 A current specification is required.

Q: Are all three parts RoHS compliant?

A: Yes. Phoenix Contact 1730670 is RoHS Compliant. Phoenix Contact 1730450 is ROHS3 Compliant (higher certification level). TE Connectivity 282857-8 is RoHS Compliant. All three meet RoHS requirements for lead-free construction.

Q: What is the MSL rating for these terminal blocks?

A: All three parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.
