Key Parameters

Substitute Part Grouping Explanation

Substitution compatibility for the TE Connectivity 1-284517-8 is determined by the following critical parameters:

Mandatory Matching Parameters:

• Number of Positions: 18
• Pitch: 0.150" (3.81mm)
• Header Orientation: Vertical
• Type: Header, Male Pins, Shrouded (4 Side)
• Mounting Type: Through Hole
• Termination Style: Solder
• Voltage - UL: 300 V
• Material Flammability Rating: UL94 V-0

Allowable Variation Parameters:

• Current - UL: Substitute parts must meet or exceed 11 A
• Operating Temperature: Substitute parts must support the required operating range
• Housing Material: Polyamide (PA66), Nylon 6/6, Polybutylene Terephthalate (PBT), or equivalent thermoplastic materials
• Contact Material: Phosphor Bronze, Brass, or Copper Alloy
• Insulation Height: 0.360" to 0.362" (9.14mm to 9.20mm)

All identified substitute parts maintain the core electrical and mechanical specifications required for direct functional replacement.

Parameter Comparison

Engineering Selection Recommendations

Primary Substitutes (Active Status, Full Compliance):

The Assmann WSW Components A-TB381-OQ18CV and Amphenol Anytek OQ1832500000G are the preferred substitutes for new designs. Both parts are active products with ROHS3 compliance and support extended operating temperatures (-40°C ~ 115°C), exceeding the original specification. Current ratings of 10 A meet the application requirements for most standard configurations.

Secondary Substitutes (Active Status, Conditional Use):

The Phoenix Contact 1844906 is an active product with ROHS3 compliance and identical insulation height to the original part. This component is suitable for applications where the operating temperature range is not critical.

The Molex 0395111018 is an active product with ROHS3 compliance. The current rating of 8 A is lower than the original specification and requires evaluation against actual circuit requirements. The operating temperature range of -40°C ~ 105°C is slightly reduced compared to the original part.

Compliance Considerations:

All substitute parts carry UL94 V-0 flammability ratings and MSL 1 moisture sensitivity levels, matching the original component. The transition from obsolete to active status ensures long-term availability and supply chain continuity. ROHS3 compliance of all substitutes supports regulatory requirements for new product development.

Frequently Asked Questions (FAQ)

Q: Can the Molex 0395111018 replace the TE Connectivity 1-284517-8 in all applications?

A: The Molex 0395111018 maintains electrical and mechanical compatibility with the original part. However, the current rating is 8 A compared to the original 11 A specification. Applications requiring the full 11 A capacity should use the Assmann A-TB381-OQ18CV or Amphenol Anytek OQ1832500000G instead.

Q: What is the difference between the Assmann A-TB381-OQ18CV and Amphenol Anytek OQ1832500000G?

A: Both parts are functionally equivalent with identical electrical specifications (18 positions, 0.150" pitch, 10 A current rating, 300 V voltage rating). The primary differences are manufacturer and housing material composition. Both support the extended operating temperature range of -40°C ~ 115°C.

Q: Are all substitute parts RoHS compliant?

A: Yes. All substitute parts carry ROHS3 compliance certification. The original TE Connectivity 1-284517-8 is marked as "Not applicable" for RoHS status due to its obsolete classification.

Q: What is the significance of the insulation height specification?

A: Insulation height determines the physical clearance between the header and the mounting surface. The original part specifies 0.362" (9.20mm). The Molex 0395111018 specifies 0.360" (9.14mm), a 0.002" (0.06mm) difference. This minor variation is within standard manufacturing tolerances and does not affect functional compatibility.

Q: Can substitute parts be used interchangeably on existing PCBs designed for the TE Connectivity 1-284517-8?

A: Yes. All substitute parts maintain identical pitch (0.150"), position count (18), mounting type (through hole), and termination style (solder). PCB footprints designed for the original part accommodate all listed substitutes without modification.

Q: Which substitute part offers the best long-term availability?

A: All substitute parts are classified as active products with current inventory levels exceeding 900 units. The Assmann A-TB381-OQ18CV and Amphenol Anytek OQ1832500000G offer the highest current ratings (10 A) and extended operating temperature ranges (-40°C ~ 115°C), supporting the broadest range of application requirements.
