RA-1011 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The RA-1011 is a 10-position receptacle housing manufactured by JST Sales America Inc., designed for 0.100" (2.54mm) pitch rectangular connector applications. This component serves as the housing structure for female socket contacts in dual-row configurations and is commonly used in inline connector assemblies. The part maintains Active product status with full RoHS compliance and unlimited moisture sensitivity rating, making it suitable for standard industrial and commercial applications. Substitute parts may be required due to inventory availability, lead time considerations, or specific application requirements within the allowed electrical and mechanical parameter ranges.

Key Parameters

Substitute Part Grouping Explanation

Substitution eligibility for the RA-1011 is determined by strict equivalence across the following critical parameters:

• Connector Type & Contact Configuration: Receptacle housing with female socket contacts
• Position Count & Pitch: Exactly 10 positions at 0.100" (2.54mm) pitch
• Row Configuration: Dual-row arrangement with 0.100" (2.54mm) row spacing
• Mounting & Termination: Free hanging inline mounting with crimp contact termination
• Physical Characteristics: Black color, suitable insulation material for the application
• Compliance: RoHS compliance and MSL rating of 1 or better

The substitute part 102387-1 (TE Connectivity AMP Connectors) meets all mandatory substitution criteria within these parameters. Both parts function as receptacle housings for identical pitch and position configurations, supporting the same contact termination method and mounting approach.

Parameter Comparison

Engineering Selection Recommendations

Both the RA-1011 and 102387-1 are Active product status components with full RoHS compliance and identical MSL ratings. Selection between these parts should be based on:

• Inventory Availability: RA-1011 has 843 units in stock; 102387-1 has 1690 units available
• Lead Time Requirements: Higher inventory of 102387-1 may support shorter procurement cycles
• Temperature Operating Range: The 102387-1 provides extended temperature capability (-65°C ~ 105°C) compared to RA-1011 (-55°C ~ 85°C), offering additional margin for applications approaching temperature extremes
• Series Compatibility: RA-1011 belongs to the RA series; 102387-1 belongs to the AMPMODU Mod IV series

Both parts satisfy the core functional and compliance requirements for 10-position, 2.54mm pitch rectangular connector housing applications with crimp termination.

Frequently Asked Questions (FAQ)

Q: Can 102387-1 be used as a direct replacement for RA-1011?

A: Yes. Both parts are 10-position receptacle housings with 0.100" (2.54mm) pitch, dual-row configuration, and crimp termination. All critical mechanical and electrical parameters are equivalent.

Q: What is the difference in operating temperature ranges?

A: RA-1011 operates from -55°C to 85°C, while 102387-1 operates from -65°C to 105°C. The 102387-1 provides extended temperature capability at both lower and upper limits.

Q: Are there packaging differences between these parts?

A: RA-1011 packaging is listed as unspecified in available data. 102387-1 is supplied in Bulk packaging. Confirm packaging requirements with your procurement specifications.

Q: Do both parts require separate contact procurement?

A: Yes. Both the RA-1011 and 102387-1 are housings only; contacts are not included and must be ordered separately.

Q: What is the significance of the polarizing key feature on 102387-1?

A: The 102387-1 includes a polarizing key feature. Verify that your application design accommodates or requires this feature before substitution.

Q: Are both parts RoHS compliant?

A: Yes. Both RA-1011 and 102387-1 are RoHS compliant with MSL rating of 1 (Unlimited).
