Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the AT04-4P-PM11 is determined by strict equivalence across the following critical parameters:

Mandatory Matching Parameters:

• Connector Type: Receptacle
• Number of Positions: 4
• Number of Rows: 2
• Contact Type: Male Pin
• Contact Termination: Crimp
• Fastening Type: Latch Holder
• Insulation Material: Thermoplastic
• Operating Temperature Range: -55°C ~ 125°C
• Features: Mounting Flange, Sealed
• Series: PanelMate™ AT
• Base Product Number: AT04-4P

Variable Parameters (Non-Critical for Substitution):

• Color (Black vs. Gray)
• Moisture Sensitivity Level
• Inventory availability

The substitute part AT04-4P-CL03 maintains all mandatory parameters while differing only in housing color and MSL rating, making it a valid parametric equivalent for applications where color specification is not a design constraint.

Parameter Comparison

Engineering Selection Recommendations

Both AT04-4P-PM11 and AT04-4P-CL03 are Active products with full ROHS3 compliance and REACH Unaffected status, meeting current regulatory requirements for electronic component manufacturing and distribution. Both parts carry identical ECCN (EAR99) and HTSUS classifications, ensuring equivalent export and tariff treatment.

Selection between these parts should be based on the following criteria:

Select AT04-4P-PM11 when:

• Black housing color is specified in the design or assembly documentation
• Color consistency with existing connector installations is required
• No moisture sensitivity constraints are present in the application

Select AT04-4P-CL03 when:

• Gray housing color is acceptable or preferred for the application
• Moisture Sensitivity Level 1 (Unlimited) rating is required
• Inventory of the primary part is unavailable

Both parts share identical electrical and mechanical specifications, including the 4-position, 2-row configuration, crimp termination, latch holder fastening, and sealed thermoplastic construction. The operating temperature range of -55°C to 125°C is maintained across both variants, ensuring thermal performance equivalence in all specified environments.

Frequently Asked Questions (FAQ)

Q: Can AT04-4P-CL03 be used as a direct replacement for AT04-4P-PM11 in existing assemblies?

A: Yes, AT04-4P-CL03 is a parametric equivalent for AT04-4P-PM11 across all electrical and mechanical specifications. The primary difference is housing color (Gray vs. Black). Substitution is valid provided color specification is not a design requirement.

Q: What is the significance of the different Moisture Sensitivity Level (MSL) ratings?

A: AT04-4P-PM11 lists MSL as Not Applicable, while AT04-4P-CL03 is rated MSL 1 (Unlimited). This indicates AT04-4P-CL03 has no moisture sensitivity constraints during storage and handling. Both parts are suitable for standard warehouse and assembly environments.

Q: Are the contact termination methods identical between these parts?

A: Yes. Both AT04-4P-PM11 and AT04-4P-CL03 use crimp contact termination with latch holder fastening. Contacts are not included with either housing and must be sourced separately.

Q: Do these parts share the same base product number?

A: Yes. Both parts are based on AT04-4P, indicating they are variants within the same product family. The suffixes (-PM11 and -CL03) denote specific housing and mounting configurations.

Q: What is the pitch specification for these connectors?

A: Pitch is not specified for these parts in the provided documentation. Contact the manufacturer for detailed dimensional specifications if pitch information is required for design validation.

Q: Are both parts compliant with current environmental regulations?

A: Yes. Both AT04-4P-PM11 and AT04-4P-CL03 are ROHS3 Compliant and REACH Unaffected, meeting current environmental and hazardous substance restrictions for electronic components.

Q: Can these receptacle housings be used with any male connector pin contact?

A: No. These receptacles are designed for use with male pin contacts compatible with the PanelMate™ AT series. Contact specifications must match the housing design for proper mating and electrical performance.
