AT04-4P-CL06 Equivalent & Substitute Parts

Part Overview

The AT04-4P-CL06 is a 4-position rectangular connector receptacle housing manufactured by Amphenol Sine Systems Corp as part of the PanelMate™ AT series. This panel-mount connector features a mounting flange, sealed design, and thermoplastic insulation rated for -55°C to 125°C operation. The housing is supplied in black and accepts male pin contacts via crimp termination with latch holder fastening. This connector is classified as Active product status with ROHS3 compliance and unlimited moisture sensitivity rating (MSL 1). Substitute parts are identified when equivalent electrical and mechanical parameters are maintained across the connector family, allowing for design flexibility and supply chain alternatives.

Substitute Part Grouping Explanation

Substitute parts for the AT04-4P-CL06 are identified within the PanelMate™ AT series based on electrical and mechanical parameter equivalence. The substitution criteria are strictly limited to parts that maintain identical specifications across the following parameters:

• Connector type (Receptacle)
• Contact type (Male Pin)
• Number of positions (4)
• Number of rows (2)
• Mounting type (Panel Mount)
• Contact termination method (Crimp)
• Fastening type (Latch Holder)
• Features (Mounting Flange, Sealed)
• Insulation material (Thermoplastic)
• Operating temperature range (-55°C ~ 125°C)
• Series designation (PanelMate™ AT)
• Compliance certifications (ROHS3, REACH Unaffected)

Variations in housing color alone do not affect electrical or mechanical compatibility and therefore do not preclude substitution. The AT04-4P-CL03 meets all substitution criteria with the only difference being housing color (Gray versus Black).

Parameter Comparison

Engineering Selection Recommendations

The AT04-4P-CL03 is a direct functional equivalent to the AT04-4P-CL06 for applications requiring a 4-position rectangular connector receptacle housing with panel-mount configuration. Both parts maintain identical electrical and mechanical specifications, including contact configuration, termination method, temperature rating, and sealed design. Both parts carry Active product status and maintain full ROHS3 compliance and REACH Unaffected designation.

Selection between AT04-4P-CL06 and AT04-4P-CL03 is determined solely by housing color requirements. The black housing of AT04-4P-CL06 and gray housing of AT04-4P-CL03 present no functional differences in connector performance, mating capability, or environmental protection. Current inventory levels show 1560 units of AT04-4P-CL03 available against 1064 units of AT04-4P-CL06, which may influence supply chain decisions.

Frequently Asked Questions (FAQ)

Q: Can AT04-4P-CL03 be used as a direct replacement for AT04-4P-CL06?

A: Yes. The AT04-4P-CL03 is electrically and mechanically equivalent to AT04-4P-CL06. All functional parameters including connector type, position count, row configuration, mounting method, termination type, fastening mechanism, temperature rating, and sealing features are identical. The only difference is housing color.

Q: Are there any compatibility issues when substituting AT04-4P-CL03 for AT04-4P-CL06?

A: No compatibility issues exist from an electrical or mechanical standpoint. Both connectors accept the same male pin contacts via crimp termination and mount identically to panel surfaces using the latch holder fastening system. Housing color does not affect connector mating or performance.

Q: Do both parts support the same operating temperature range?

A: Yes. Both AT04-4P-CL06 and AT04-4P-CL03 are rated for -55°C to 125°C operation with thermoplastic insulation material.

Q: Are both parts RoHS compliant?

A: Yes. Both AT04-4P-CL06 and AT04-4P-CL03 carry ROHS3 compliance certification and REACH Unaffected status.

Q: What is the moisture sensitivity level for these connectors?

A: Both parts carry MSL 1 (Unlimited) rating, indicating no moisture sensitivity restrictions for storage or handling.

Q: Do these connectors include contacts?

A: No. Both AT04-4P-CL06 and AT04-4P-CL03 are supplied as housings only. Male pin contacts must be sourced separately and installed via crimp termination.

Q: Can I mix AT04-4P-CL06 and AT04-4P-CL03 in the same application?

A: Yes. Since both connectors are functionally identical, they can be used interchangeably within the same system or application without affecting performance or compatibility.
