Switchcraft 09BL4M Circular Connector - Equivalent & Substitute Parts

Part Overview

The Switchcraft 09BL4M is a 4-position circular connector plug with male pins, designed for solder termination. This connector features a DIN (210 Degree) shell size with push-pull fastening, zinc die-cast construction, and nickel plating. The part is currently classified as obsolete, which necessitates identification of active equivalent components to maintain supply chain continuity for applications requiring this connector type.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the 09BL4M is determined by strict alignment across the following critical parameters:

• Connector type and pin configuration (Plug, Male Pins, 4-position)
• Shell size and insert specification (DIN 210 Degree)
• Termination method (Solder)
• Fastening mechanism (Push-Pull)
• Mounting configuration (Free Hanging In-Line)
• Material and finish specifications (Zinc Die Cast, Nickel Shell Finish, Tin Contact Finish)
• Mechanical features (Backshell, Cable Clamp, Strain Relief)

The 09BL4MX meets all these criteria and qualifies as a direct substitute. The primary distinction is product status: 09BL4M is obsolete, while 09BL4MX is active and RoHS3 compliant.

Parameter Comparison

Engineering Selection Recommendations

The 09BL4MX is the appropriate selection for new designs and ongoing production requiring a 4-position DIN circular connector plug with solder termination. As an active product from the same manufacturer with identical mechanical and electrical specifications, it provides direct functional equivalence to the obsolete 09BL4M.

The 09BL4MX offers the additional advantage of RoHS3 compliance, making it suitable for applications subject to regulatory requirements restricting hazardous substances. Both parts maintain REACH unaffected status and identical export classification (EAR99).

Frequently Asked Questions (FAQ)

Q: Can 09BL4MX be used as a direct replacement for 09BL4M in existing applications?

A: Yes. The 09BL4MX maintains identical specifications across all mechanical, electrical, and material parameters. Pin configuration, shell size, termination method, and fastening mechanism are unchanged, ensuring compatibility with existing mating connectors and PCB layouts.

Q: What is the primary difference between these parts?

A: The 09BL4M is obsolete, while 09BL4MX is an active product. Additionally, 09BL4MX is RoHS3 compliant, whereas 09BL4M is RoHS non-compliant. All functional specifications remain identical.

Q: Are there packaging differences between 09BL4M and 09BL4MX?

A: Yes. The 09BL4M is supplied in standard packaging, while 09BL4MX is supplied in bulk packaging. This distinction affects order quantities and handling but does not impact component performance or compatibility.

Q: Which part should be specified for new designs?

A: The 09BL4MX should be specified for all new designs. As an active product with current manufacturing support and regulatory compliance, it ensures long-term supply chain availability and meets modern environmental standards.

Q: Are the electrical and mechanical interfaces identical?

A: Yes. Both parts feature identical DIN (210 Degree) shell size, 4-position configuration, push-pull fastening, solder termination, and mechanical features including backshell, cable clamp, and strain relief.
