RA-1611 Rectangular Connector Housing - Equivalent & Substitute Parts

Part Overview

The RA-1611 is a 16-position receptacle housing manufactured by JST Sales America Inc., designed for 0.100" (2.54mm) pitch applications. This connector housing is part of the RA series and is classified as a free-hanging, in-line receptacle with crimp termination. The part is currently active in production with RoHS compliance and unlimited moisture sensitivity rating. Substitute parts are identified to provide alternative sourcing options when the primary part is unavailable or when design requirements permit equivalent configurations.

Key Parameters

Substitute Part Grouping Explanation

Substitution of the RA-1611 is determined by strict equivalence across the following critical parameters:

• Connector configuration: Receptacle housing with female socket contacts
• Position count and pitch: 16 positions at 0.100" (2.54mm) spacing
• Row configuration: 2 rows with 0.100" (2.54mm) row spacing
• Termination method: Crimp contact termination
• Mounting style: Free hanging, in-line orientation
• Color and material: Black housing with thermoplastic or glass-filled PBT insulation
• Compliance: RoHS compliant with MSL 1 rating

The substitute part 102387-3 (TE Connectivity AMP Connectors) meets all critical dimensional and functional parameters. Differences in operating temperature range and insulation material composition do not preclude substitution when the application environment and electrical requirements fall within the substitute part's specifications.

Parameter Comparison

Engineering Selection Recommendations

Both the RA-1611 and 102387-3 are active production parts with RoHS compliance and MSL 1 ratings. Selection between these parts should be based on:

RA-1611 (JST Sales America Inc.): Select when the application requires the specific JST RA series form factor or when the operating temperature range of -55°C to 85°C is sufficient for the intended environment.

102387-3 (TE Connectivity AMP Connectors): Select when extended operating temperature capability (-65°C to 105°C) is required, when the polarizing key feature provides design benefit, or when TE Connectivity supply chain availability is preferred. The thermoplastic insulation material meets the same functional requirements as glass-filled PBT for this connector class.

Both parts are suitable for applications requiring 16-position, 2.54mm pitch receptacle housings with crimp termination and free-hanging mounting.

Frequently Asked Questions (FAQ)

Q: Can 102387-3 be used as a direct replacement for RA-1611?

A: Yes. Both parts share identical pitch (0.100" / 2.54mm), position count (16), row configuration (2 rows), mounting type (free hanging, in-line), contact termination (crimp), and color (black). Both are RoHS compliant with MSL 1 rating. The substitute part has an extended operating temperature range and includes a polarizing key feature.

Q: What is the difference in insulation material between the two parts?

A: The RA-1611 uses polybutylene terephthalate (PBT) with glass filler, while the 102387-3 uses thermoplastic material. Both materials are suitable for rectangular connector housings in this pitch class and provide equivalent electrical and mechanical performance for standard applications.

Q: Does the polarizing key on 102387-3 affect compatibility?

A: The polarizing key on 102387-3 is an additional feature that prevents incorrect mating orientation. This feature does not prevent compatibility with standard RA-1611 mating components; however, the presence of the key means the 102387-3 housing will only mate with compatible plugs designed for keyed configurations.

Q: Are there any temperature limitations when substituting these parts?

A: The RA-1611 operates from -55°C to 85°C, while 102387-3 operates from -65°C to 105°C. If your application requires temperatures below -55°C or above 85°C, the RA-1611 is not suitable. The 102387-3 can be used in applications within the RA-1611 temperature range without limitation.

Q: Do both parts require the same contact specifications?

A: Yes. Both housings are designed for crimp termination with female socket contacts at 0.100" (2.54mm) pitch. Contact selection and termination procedures should follow the respective manufacturer's specifications for each housing series.

Q: What is the significance of MSL 1 rating for both parts?

A: MSL 1 (Moisture Sensitivity Level 1) indicates unlimited shelf life without moisture control requirements. Both parts can be stored and handled under standard conditions without special desiccant packaging or baking procedures prior to assembly.
