TE Connectivity AMP Connectors 284518-8 Terminal Block Header Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 284518-8 is an 8-position terminal block header with male pins, shrouded on 2 sides, designed for vertical through-hole mounting with 0.150" (3.81mm) pitch spacing. This component is classified as Active product status and is RoHS3 compliant. Substitute parts are identified when equivalent electrical and mechanical parameters align with the main part specifications, enabling direct functional replacement in applications where the core performance characteristics remain unchanged.

Key Parameters

Substitute Part Grouping Explanation

Substitute parts for the TE Connectivity 284518-8 are identified based on strict alignment of core electrical and mechanical parameters. The substitution logic is based on the following criteria:

Primary Matching Parameters:

• Number of Positions: 8
• Pitch: 0.150" (3.81mm)
• Header Orientation: Vertical
• Type: Header with Male Pins
• Termination Style: Solder
• Voltage - UL: 300 V
• Contact Mating Finish: Tin
• RoHS Status: ROHS3 Compliant
• Moisture Sensitivity Level: 1 (Unlimited)

Secondary Considerations:

• Shrouding configuration (2-side vs. 4-side) represents a mechanical variation that does not affect electrical substitution capability
• Current rating variations (11 A vs. 10 A) fall within acceptable operational ranges for equivalent terminal block applications
• Operating temperature ranges (-40°C ~ 110°C vs. -40°C ~ 115°C or -30°C ~ 105°C) represent acceptable thermal envelope differences
• Contact material composition (Phosphor Bronze vs. Copper Alloy vs. Brass) and housing material differences do not preclude functional equivalence when electrical and mechanical interfaces remain compatible

Parameter Comparison

Engineering Selection Recommendations

TE Connectivity AMP Connectors 284518-8 (Primary Part)

The 284518-8 maintains Active product status with full RoHS3 compliance and ROHS3 Compliant certification. This part is suitable for applications requiring 11 A current capacity at 300 V with operating temperatures spanning -40°C to 110°C. The 2-side shrouded configuration provides standard EMI containment for vertical through-hole PCB mounting.

OQ0832500000G (Amphenol Anytek) - Substitute Option

The OQ0832500000G is an Active product with ROHS3 Compliant status and REACH Unaffected designation. This substitute maintains 300 V voltage rating and operates across -40°C to 115°C, providing extended upper temperature capability. The 4-side shrouded design offers enhanced EMI shielding compared to the 2-side configuration. Current rating is 10 A, which is 1 A lower than the primary part. This substitute is suitable for applications where the enhanced shrouding and extended temperature range provide operational advantages and the 10 A current capacity is sufficient.

OSTOQ083250 (On Shore Technology Inc.) - Substitute Option

The OSTOQ083250 is an Active product with ROHS3 Compliant status and REACH Unaffected designation. This substitute maintains 300 V voltage rating and operates across -30°C to 105°C. The 4-side shrouded design provides enhanced EMI containment. Current rating and flammability rating are not specified in available documentation. The insulation height of 0.138" (3.50mm) differs from the primary part specification of 0.362" (9.20mm), representing a significant mechanical variation. This substitute is suitable for applications where the 4-side shrouding is required and the reduced insulation height is compatible with PCB layout constraints.

Frequently Asked Questions (FAQ)

Q: Can the OQ0832500000G substitute for the 284518-8 in all applications?

A: The OQ0832500000G is electrically compatible for applications requiring 10 A or less at 300 V. The primary differences are the 4-side shrouding (versus 2-side) and extended operating temperature range to 115°C. Mechanical fit and PCB layout must be verified due to the 4-side shrouding configuration.

Q: What is the significance of the shrouding difference between 2-side and 4-side configurations?

A: The 2-side shrouding on the 284518-8 provides EMI containment on two opposing sides. The 4-side shrouding on both substitute parts provides complete perimeter EMI shielding. The choice depends on application-specific EMI requirements and available PCB space.

Q: Is the OSTOQ083250 suitable as a direct replacement for the 284518-8?

A: The OSTOQ083250 shares the same 8-position, 3.81mm pitch, vertical orientation, and 300 V rating. However, the insulation height is significantly different (0.138" versus 0.362"), which may affect PCB mounting compatibility. Current rating is not specified for this part. Mechanical verification is required before substitution.

Q: What are the compliance differences between the three parts?

A: All three parts are ROHS3 Compliant and have MSL rating of 1 (Unlimited). The 284518-8 has undefined REACH status, while both substitute parts are REACH Unaffected. All three parts carry EAR99 ECCN classification and identical HTSUS codes.

Q: How do the operating temperature ranges affect substitution decisions?

A: The 284518-8 operates from -40°C to 110°C. The OQ0832500000G extends the upper limit to 115°C, providing 5°C additional margin. The OSTOQ083250 operates from -30°C to 105°C, reducing both the lower and upper temperature capability. Application thermal requirements determine which part is appropriate.

Q: Are there current rating limitations when substituting parts?

A: The 284518-8 is rated for 11 A at UL specifications. The OQ0832500000G is rated for 10 A. The OSTOQ083250 does not specify a current rating. Applications requiring the full 11 A capacity must use the primary part or verify that the OQ0832500000G's 10 A rating is sufficient for the specific circuit.

Q: What contact material differences exist between these parts?

A: The 284518-8 uses Phosphor Bronze contacts. The OQ0832500000G uses Copper Alloy contacts. The OSTOQ083250 uses Brass contacts. All three maintain Tin mating finish. Contact material composition does not affect electrical substitution capability when mating finish specifications are identical.
