Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector housings is determined by strict equivalence across core electrical and mechanical parameters. The following parameters establish substitution validity:

Critical Matching Parameters:

• Connector type (receptacle)
• Contact type (female socket)
• Number of positions (21)
• Pitch specification (0.100" / 2.54mm)
• Number of rows (1)
• Mounting configuration (free hanging, in-line)
• Contact termination method (crimp)
• Fastening mechanism (locking ramp)
• Moisture sensitivity level (MSL 1)

The substitute part 2-1375820-1 maintains equivalence across all critical parameters while offering active product status and enhanced compliance documentation. Variations in color (natural versus white) and series designation (CST-100 versus CST-100 II) do not affect functional interchangeability for applications requiring these core specifications.

Parameter Comparison

Engineering Selection Recommendations

For New Designs and Production: The substitute part 2-1375820-1 is the appropriate selection for applications currently specified with 2-770602-1. This substitute maintains complete functional equivalence across all critical electrical and mechanical parameters while offering active product status. The CST-100 II series provides current manufacturing support and availability.

For Obsolete Part Replacement: The 2-770602-1 is classified as obsolete. Transition to 2-1375820-1 is supported by identical core specifications and enhanced compliance documentation. The substitute part carries RoHS3 compliance certification, providing improved regulatory alignment for new applications.

Compliance Considerations: Both parts share identical ECCN (EAR99) and HTSUS (8536.69.8000) classifications. The substitute part provides explicit RoHS3 compliance status, whereas the main part does not specify RoHS compliance. Both parts maintain MSL 1 rating, indicating unlimited moisture sensitivity protection requirements.

Frequently Asked Questions (FAQ)

Q: Can 2-1375820-1 directly replace 2-770602-1 in existing assemblies?

A: Yes. The substitute part maintains equivalence across all critical parameters: 21-position receptacle housing, 0.100" (2.54mm) pitch, female socket contacts, crimp termination, locking ramp fastening, and free hanging in-line mounting. The color difference (white versus natural) does not affect electrical or mechanical function.

Q: What is the significance of the series change from CST-100 to CST-100 II?

A: The series designation indicates product line evolution. CST-100 II represents the current generation of the connector housing series. Both series maintain identical specifications for the 21-position, 2.54mm pitch receptacle configuration, ensuring functional interchangeability.

Q: Are there any compatibility issues with existing mating connectors?

A: No. The substitute part maintains identical pitch (0.100" / 2.54mm), position count (21), and mounting configuration (free hanging, in-line). Existing mating connectors designed for 2-770602-1 are fully compatible with 2-1375820-1.

Q: What does MSL 1 (Unlimited) mean for these connectors?

A: MSL 1 indicates the lowest moisture sensitivity level. These connector housings require no special moisture protection or baking procedures prior to assembly, allowing unlimited shelf life under standard storage conditions.

Q: Does the packaging difference affect component selection?

A: The main part lists packaging as undefined, while the substitute specifies bulk packaging. Packaging format does not affect the connector housing specifications or functional performance. Packaging selection depends on procurement and assembly process requirements.

Q: Are both parts compliant with current export regulations?

A: Yes. Both parts carry identical ECCN classification (EAR99) and HTSUS code (8536.69.8000), indicating equivalent export control status. The substitute part provides explicit RoHS3 compliance documentation for enhanced regulatory alignment.

Q: What is the contact material specification for these housings?

A: The substitute part specifies polyamide (PA) nylon with glass filling for the insulation material. The main part does not provide explicit material documentation. Both parts are designed for crimp-type contacts and maintain identical electrical performance characteristics.

Q: Can these connector housings be used in high-temperature applications?

A: The substitute part specifies an operating temperature range of -55°C to 105°C. The main part does not provide explicit temperature specifications. Applications requiring temperature performance confirmation should reference the substitute part's documented operating range.
