Key Parameters

Substitute Part Grouping Explanation

The substitute part G11LAC-P03LPH0-0000 (ODU MINI-SNAP® L series) is grouped as an equivalent based on the following critical parameters:

• Connector type: Receptacle with female sockets
• Position count: 3 positions
• Termination method: Solder cup
• Mounting configuration: Panel mount with bulkhead rear side nut
• Fastening mechanism: Push-Pull
• Electrical performance: 12A current rating
• Contact finish: Gold plating on mating surfaces
• Shielding: Shielded design
• Ingress protection: IP50 rating
• Compliance: ROHS3 compliant with MSL 1 rating

Both parts satisfy the core functional and electrical requirements for circular connector receptacle applications requiring solder cup termination and push-pull fastening.

Parameter Comparison

Engineering Selection Recommendations

Both EGA.1B.303.CLL and G11LAC-P03LPH0-0000 maintain active product status and satisfy ROHS3 compliance requirements with MSL 1 rating. Selection between these parts should be based on application-specific operating temperature requirements. The EGA.1B.303.CLL supports extended temperature operation from -55°C to 250°C, while the G11LAC-P03LPH0-0000 operates within -40°C to 120°C range. For applications requiring operation beyond 120°C or below -40°C, the EGA.1B.303.CLL is the appropriate selection. Both parts are suitable for industrial, medical, military, and testing equipment applications where the specified temperature range is acceptable.

Frequently Asked Questions (FAQ)

Q: What determines compatibility between EGA.1B.303.CLL and G11LAC-P03LPH0-0000?

A: Compatibility is established through matching connector type (receptacle, female sockets), position count (3), termination method (solder cup), mounting configuration (panel mount with bulkhead rear side nut), fastening mechanism (push-pull), current rating (12A), contact finish (gold), shielding (shielded), and ingress protection (IP50). Both parts meet these core parameters.

Q: Are there differences in operating temperature ranges?

A: Yes. The EGA.1B.303.CLL operates from -55°C to 250°C, while the G11LAC-P03LPH0-0000 operates from -40°C to 120°C. Applications requiring extended temperature operation must use the EGA.1B.303.CLL.

Q: Do both parts have the same shell finish?

A: The shell materials are identical (brass), but finishes differ slightly. EGA.1B.303.CLL uses chrome finish, while G11LAC-P03LPH0-0000 uses chrome over nickel. Both provide equivalent corrosion protection for the specified applications.

Q: Are both parts RoHS compliant?

A: Yes, both EGA.1B.303.CLL and G11LAC-P03LPH0-0000 are ROHS3 compliant with MSL 1 (unlimited) moisture sensitivity level rating.

Q: What is the current handling capacity of these connectors?

A: Both connectors are rated for 12A continuous current, meeting standard industrial and measurement equipment requirements.
