H3161-T6 Equivalent & Substitute Parts

Part Overview

The H3161-T6 is a pin receptacle connector manufactured by Harwin Inc., designed for 0.039" (1.00mm) pin diameter applications with press-fit, knurled termination and no tail configuration. This component is classified as obsolete, making identification of active equivalent parts essential for ongoing production and maintenance applications. The H3161-T6 features a tin contact finish and maintains ROHS3 compliance. Due to its obsolete status, sourcing active alternatives is necessary for new designs and component replenishment.

Key Parameters

Substitute Part Grouping Explanation

The H3161-46 qualifies as a direct substitute for the H3161-T6 based on the following critical parameters:

Matching Parameters:

• Manufacturer: Harwin Inc. (same manufacturer ensures design compatibility)
• Category: Terminals (identical component classification)
• Tail Type: No Tail (identical mechanical configuration)
• Termination Type: Press-Fit, Knurled (identical termination method)
• Mounting Hole Diameter: 0.075" ~ 0.077" (1.91mm ~ 1.96mm) (identical PCB interface)
• Flange Diameter: 0.092" ~ 0.093" (mechanically compatible)
• Contact Finish: Tin (identical surface treatment)
• RoHS Status: ROHS3 Compliant (equivalent regulatory compliance)
• REACH Status: REACH Unaffected (equivalent regulatory compliance)

Critical Difference:

• Accepts Pin Diameter: H3161-46 accepts 0.035" ~ 0.041" (0.89mm ~ 1.05mm), which encompasses the H3161-T6 specification of 0.039" (1.00mm) within its tolerance range

The H3161-46 is an active product with superior availability (1194 pcs in stock versus 912 pcs for the obsolete H3161-T6) and provides additional technical specifications including socket depth, contact material (Beryllium Copper), insertion force, and operating temperature range.

Parameter Comparison

Engineering Selection Recommendations

The H3161-46 is the appropriate substitute for the obsolete H3161-T6 based on the following engineering criteria:

Product Status Alignment: The H3161-46 is an active product with confirmed current manufacturing and inventory availability, addressing the obsolescence of the H3161-T6.

Regulatory Compliance: Both components maintain ROHS3 compliance and REACH unaffected status, ensuring equivalent regulatory standing for applications requiring these certifications.

Mechanical Compatibility: Identical mounting hole diameter (0.075" ~ 0.077"), no-tail configuration, and press-fit termination method ensure direct PCB integration without design modification.

Electrical Compatibility: The H3161-46 pin diameter acceptance range of 0.035" ~ 0.041" (0.89mm ~ 1.05mm) encompasses the H3161-T6 specification of 0.039" (1.00mm), confirming functional compatibility with existing mating pins.

Manufacturing Continuity: Both components are manufactured by Harwin Inc., maintaining design consistency and supply chain reliability.

Frequently Asked Questions (FAQ)

Q: Can the H3161-46 directly replace the H3161-T6 in existing designs?

A: Yes. The H3161-46 accepts pin diameters of 0.035" ~ 0.041" (0.89mm ~ 1.05mm), which includes the H3161-T6 specification of 0.039" (1.00mm). Mounting hole diameter, flange diameter, and termination method are mechanically compatible. No PCB redesign is required.

Q: What is the significance of the pin diameter tolerance range in the H3161-46?

A: The H3161-46 specifies a tolerance range of 0.035" ~ 0.041" (0.89mm ~ 1.05mm) rather than a fixed dimension. This range encompasses the H3161-T6 nominal specification of 0.039" (1.00mm), confirming that mating pins designed for the H3161-T6 will function within the H3161-46 acceptance parameters.

Q: Are there differences in overall length between these components?

A: The H3161-T6 has an overall length of 0.219" (5.56mm), while the H3161-46 measures 0.207" (5.26mm). This 0.012" (0.30mm) difference is minimal and does not affect PCB mounting or connector interface compatibility.

Q: What additional specifications does the H3161-46 provide?

A: The H3161-46 provides contact material specification (Beryllium Copper), socket depth (0.140" / 4.66mm), insertion force range (3.00N ~ 9.00N), and operating temperature range (-55°C ~ 125°C). These specifications were not provided for the H3161-T6.

Q: Are both components RoHS and REACH compliant?

A: Yes. Both the H3161-T6 and H3161-46 are ROHS3 compliant and REACH unaffected, meeting equivalent regulatory requirements for restricted substance compliance.

Q: What is the packaging difference between these components?

A: The H3161-T6 packaging specification is not provided. The H3161-46 is supplied in bulk packaging. Confirm packaging requirements with your procurement specifications.
