Key Parameters

Substitute Part Grouping Explanation

Substitution for the Pomona Electronics 6855 is determined by strict alignment of the following electrical and mechanical parameters:

Critical Matching Parameters:

• Connector type: Receptacle with male pins
• Number of positions: 5
• Shell size: XLR
• Mounting configuration: Panel mount with flange
• Termination method: Solder cup
• Fastening mechanism: Latch lock

Direct Substitute (Functionally Equivalent): The ITT Cannon XLR532 meets all critical parameters and serves as a direct substitute. Both components feature identical connector architecture, position count, shell size, mounting configuration, and termination method. The XLR532 is active in production, ensuring availability and supply chain continuity.

Similar Substitute (Pin Configuration Difference): The ITT Cannon XLR531F77 shares the same shell size, mounting type, flange feature, solder cup termination, and latch lock fastening. However, this part features female sockets rather than male pins, making it suitable only for applications where the mating interface requires female socket contacts instead of male pins.

Parameter Comparison

Engineering Selection Recommendations

For Direct Replacement: Select the ITT Cannon XLR532 when a functionally equivalent substitute is required. This part maintains identical connector architecture and pin configuration while offering active product status, ensuring long-term availability and supply chain reliability. Both components comply with EAR99 export classification and share the same HTSUS code.

For Pin Configuration Adaptation: The ITT Cannon XLR531F77 is applicable only when the system design permits or requires female socket contacts instead of male pins. This part is active in production and meets the same mechanical mounting and termination specifications. Selection of this part requires confirmation that the mating interface is compatible with female socket contacts.

Compliance Considerations: All substitute parts maintain EAR99 export classification alignment with the original Pomona 6855. The ITT Cannon parts provide specified operating temperature ranges (-35°C ~ 125°C) and voltage ratings (133V/133VAC) not documented for the original part, offering enhanced technical specification clarity for system design validation.

Frequently Asked Questions (FAQ)

Q: Can the ITT Cannon XLR532 directly replace the Pomona 6855? A: Yes. The XLR532 matches all critical parameters: 5-position XLR receptacle with male pins, panel mount flange configuration, solder cup termination, and latch lock fastening. The primary difference is shell material (aluminum vs. zinc die cast) and contact finish (silver vs. tin), which do not affect functional compatibility.

Q: What is the key difference between the XLR532 and XLR531F77? A: The XLR532 features male pins, while the XLR531F77 features female sockets. Both share identical shell size, mounting configuration, and termination method. Selection depends on whether your mating interface requires male or female contacts.

Q: Why is the Pomona 6855 listed as obsolete? A: Obsolete status indicates the part is no longer manufactured by Pomona Electronics. The ITT Cannon XLR532 provides an active, in-production equivalent for continued system support and new designs.

Q: Are there packaging differences between these parts? A: Yes. The Pomona 6855 packaging is not specified. The ITT Cannon XLR532 is supplied in trays, while the XLR531F77 is supplied in bulk. Packaging selection should align with procurement and assembly requirements.

Q: Do all parts meet the same compliance standards? A: All three parts share EAR99 export classification and the same HTSUS code (8536.69.4020). The Pomona 6855 is documented as ROHS3 compliant. Compliance verification for ITT Cannon parts should be confirmed with the manufacturer for specific applications.
