Adafruit 1802 1/4" (6.35MM) DIY Mono Plug - Equivalent & Substitute Parts

Part Overview

The Adafruit 1802 is a 6.35mm (0.250", 1/4") headphone phone plug mono connector with solder eyelet termination, designed for free-hanging in-line applications. This connector is classified as obsolete, making identification of functionally equivalent alternatives essential for ongoing design support and component procurement. The mono plug configuration with two conductors and two contacts serves standard audio signal applications requiring a 1/4" headphone jack interface.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the Adafruit 1802 is determined by strict adherence to the following core parameters:

Critical Matching Parameters:

• Connector Type: Phone Plug (male gender)
• Mating Diameter: 6.35mm (0.250", 1/4") - Headphone standard
• Signal Configuration: Mono (2 conductors, 2 contacts)
• Mounting Type: Free Hanging (In-Line)
• Termination Method: Solder Eyelet(s)
• Shielding: Unshielded

The Amphenol Audio ACPM-GN meets all critical substitution criteria. Both connectors share identical mating diameter specifications, mono signal architecture, solder eyelet termination, and free-hanging mounting configuration. The ACPM-GN maintains functional equivalence across all electrical and mechanical interfaces required for direct component replacement in applications originally designed for the Adafruit 1802.

Parameter Comparison

Engineering Selection Recommendations

The Amphenol Audio ACPM-GN is the direct functional equivalent for the obsolete Adafruit 1802. Selection of the ACPM-GN is supported by:

Product Status: The ACPM-GN maintains active production status, ensuring long-term component availability and supply chain continuity compared to the obsolete Adafruit 1802.

Compliance & Certifications: The ACPM-GN is ROHS3 compliant and REACH unaffected, meeting current regulatory requirements for electronic component procurement. Both connectors share identical ECCN classification (EAR99).

Mechanical & Electrical Compatibility: The ACPM-GN provides specified operating temperature range (-25°C ~ 70°C) and current rating (10 A), with documented contact material composition (Nickel-plated Brass) and housing material (Zinc Alloy). These specifications support reliable performance in standard audio signal applications.

Physical Dimensions: The mating length differential (1.220" vs. 1.190") represents a 0.030" (0.76mm) variation within acceptable tolerance for free-hanging in-line connector applications and does not compromise mechanical fit or electrical interface integrity.

Frequently Asked Questions (FAQ)

Q: Can the Amphenol Audio ACPM-GN directly replace the Adafruit 1802 in existing designs?

A: Yes. Both connectors share identical mating diameter (6.35mm), mono signal configuration (2 conductors, 2 contacts), solder eyelet termination, and free-hanging mounting type. The 0.030" mating length difference does not affect functional compatibility in standard audio applications.

Q: What is the significance of the Adafruit 1802 being classified as obsolete?

A: Obsolete status indicates the component is no longer manufactured by Adafruit Industries LLC. The ACPM-GN, maintained in active production by Amphenol Audio, provides continuity for applications requiring 1/4" mono headphone plug connectors and ensures ongoing component availability.

Q: Are there any compliance differences between the two connectors?

A: The ACPM-GN provides documented ROHS3 compliance and REACH unaffected status. Both connectors share EAR99 ECCN classification. The ACPM-GN's compliance documentation supports procurement in regulated environments.

Q: What are the packaging differences?

A: The Adafruit 1802 packaging specification is not provided. The ACPM-GN is supplied in bulk packaging and includes three pieces per connector unit: the connector body, handle, and insulator tube.

Q: How do the electrical specifications compare?

A: The ACPM-GN specifies 10 A current rating and -25°C ~ 70°C operating temperature range. The Adafruit 1802 electrical specifications are not documented. For applications requiring specific current or temperature performance, the ACPM-GN specifications define the operational envelope for this connector category.

Q: Are there any mechanical considerations for substitution?

A: The mating length difference (1.220" vs. 1.190") is 0.030" (0.76mm). This variation is within standard tolerance for free-hanging connectors and does not affect panel mounting, cable routing, or mating interface geometry in typical audio applications.
