Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for rectangular connector housings is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle housing with female socket contacts
• Position Count & Pitch: 12 positions at 0.098" (2.50mm) pitch
• Row Configuration: Single row layout
• Mounting & Termination: Free hanging in-line mounting with crimp termination
• Material & Environmental Compliance: Polyamide (PA66) insulation, ROHS3 compliance, MSL 1 rating

The substitute part 1-440133-2 (TE Connectivity AMP Connectors) meets all critical electrical and mechanical parameters. Both parts are receptacle housings with identical position count, pitch, row configuration, and termination method. Both utilize PA66 insulation material and maintain ROHS3 compliance with MSL 1 rating.

Parameter Comparison

Engineering Selection Recommendations

Both EHR-12 and 1-440133-2 are active production parts with full ROHS3 compliance and REACH unaffected status. The EHR-12 operates within -25°C to 85°C, while the 1-440133-2 extends to -25°C to 105°C. Selection between these parts should be based on application temperature requirements and supply availability. The 1-440133-2 offers higher inventory availability (24062 units) compared to EHR-12 (1583 units). Both parts carry MSL 1 rating and identical electrical and mechanical specifications for the 12-position, 2.50mm pitch receptacle housing configuration.

Frequently Asked Questions (FAQ)

Q: Can 1-440133-2 replace EHR-12 in all applications?

A: Yes, provided the application operating temperature does not exceed 85°C. The 1-440133-2 supports extended temperature operation to 105°C, making it suitable for higher temperature environments where EHR-12 may not be appropriate.

Q: Are the contact compatibility and crimp specifications identical?

A: Both parts are 12-position receptacle housings with crimp termination at 2.50mm pitch. Contact compatibility is determined by pitch and position count, which are identical. Verify that crimp contact specifications match your assembly equipment and contact supplier documentation.

Q: What is the significance of the MSL 1 rating?

A: MSL 1 indicates unlimited shelf life with no moisture sensitivity restrictions. Both parts can be stored and handled without special moisture control measures.

Q: Are there any mechanical mounting differences?

A: Both parts feature free hanging in-line mounting configuration. Mechanical compatibility depends on mating connector design and PCB layout, which are not affected by the housing manufacturer selection.

Q: Do both parts meet the same regulatory requirements?

A: Yes. Both EHR-12 and 1-440133-2 are ROHS3 compliant, REACH unaffected, and classified as EAR99 for export control purposes.
