Key Parameters

Substitute Part Grouping Explanation

The Switchcraft 855X qualifies as a direct equivalent substitute for the 858 based on the following critical parameters:

• Identical mating diameter: 2.46mm ID (0.097")
• Identical signal configuration: Mono, 2 conductors
• Identical connector type: Phone Plug, Male gender
• Identical termination method: Solder Eyelet(s)
• Identical mounting type: Free Hanging (In-Line)
• Identical electrical ratings: 125VAC, 125 mA
• Identical operating temperature range: -20°C ~ 65°C
• Same manufacturer: Switchcraft Inc.
• Same series: MICRO-PLUG®

The primary difference is packaging: the 855X is supplied in Bulk packaging, whereas the 858 packaging specification is not detailed. Both parts are Active status products with full inventory availability.

Parameter Comparison

Engineering Selection Recommendations

The Switchcraft 855X is a direct functional equivalent to the 858 for all electrical, mechanical, and dimensional specifications. Selection between these parts should be based on:

• Inventory availability: Both parts are in stock; choose based on project quantity requirements
• Packaging requirements: The 855X is supplied in Bulk packaging; confirm packaging compatibility with assembly processes
• Compliance requirements: The 855X carries ROHS3 and REACH certifications; if regulatory compliance is mandatory, the 855X is the specified choice
• Lead time and cost: Consult current pricing and delivery schedules from authorized distributors

Both parts are Active status products from the same manufacturer and series, ensuring consistent performance and reliability in equivalent applications.

Frequently Asked Questions (FAQ)

Q: Can the Switchcraft 855X be used as a direct replacement for the 858?

A: Yes. Both connectors share identical electrical ratings (125VAC, 125 mA), mechanical dimensions (2.46mm ID), signal configuration (Mono, 2 conductors), and termination method (Solder Eyelet). They are functionally interchangeable in all applications where the 858 is specified.

Q: What is the difference between the 858 and 855X?

A: The primary documented difference is packaging: the 855X is supplied in Bulk format. The 855X also includes specified material and compliance information (Nickel plating, Copper Alloy body, ROHS3 Compliant, REACH Unaffected) that are not detailed for the 858.

Q: Are there any compatibility issues when substituting the 855X for the 858?

A: No compatibility issues exist for electrical or mechanical interfaces. Both connectors are identical in mating diameter, contact configuration, and electrical performance. Confirm that Bulk packaging meets your assembly and handling requirements.

Q: What certifications apply to these connectors?

A: The 855X is ROHS3 Compliant and REACH Unaffected. Certification status for the 858 is not specified in available documentation. If regulatory compliance is a project requirement, the 855X is the documented choice.

Q: Can these connectors be used interchangeably in production?

A: Yes, provided that packaging and compliance requirements are met. Both parts are Active status products from Switchcraft Inc. with identical functional specifications. Update bill of materials and procurement documentation to reflect the selected part number.
