TE Connectivity AMP Connectors 1-1375820-1 Equivalent & Substitute Parts

Part Overview

The TE Connectivity AMP Connectors 1-1375820-1 is an 11-position rectangular connector receptacle housing designed for 0.100" (2.54mm) pitch applications. This connector operates within the CST-100 II series and is classified as Active product status. The housing accommodates female socket contacts with crimp termination and locking ramp fastening. Substitute parts become necessary when the primary part experiences supply constraints, obsolescence of related components, or when alternative series options provide equivalent electrical and mechanical performance within the same connector category.

Key Parameters

Substitute Part Grouping Explanation

Substitution of rectangular connector housings is determined by strict equivalence across critical electrical and mechanical parameters. The following parameters establish substitution validity for the 1-1375820-1:

Critical Matching Parameters:

• Connector Type: Receptacle
• Contact Type: Female Socket
• Number of Positions: 11
• Pitch: 0.100" (2.54mm)
• Number of Rows: 1
• Mounting Type: Free Hanging (In-Line)
• Contact Termination: Crimp
• Fastening Type: Locking Ramp
• Operating Temperature Range: -55°C ~ 105°C
• Insulation Material: Polyamide (PA), Nylon, Glass Filled
• Moisture Sensitivity Level: 1 (Unlimited)

The substitute part 1-770602-1 maintains equivalence across all critical parameters. Variations in color (White versus Natural) and series designation (CST-100 II versus CST-100) do not affect electrical or mechanical compatibility. Product status differences (Active versus Obsolete) reflect manufacturing lifecycle positioning rather than functional capability.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection: 1-1375820-1

The 1-1375820-1 is the recommended primary selection. This part maintains Active product status, ensuring continued availability and manufacturer support. RoHS Compliance certification is explicitly confirmed, meeting regulatory requirements for restricted substances in electrical and electronic equipment. The CST-100 II series designation indicates current generation design standards.

Substitute Selection: 1-770602-1

The 1-770602-1 functions as a direct electrical and mechanical equivalent. All critical connector parameters match the primary part. However, this part carries Obsolete product status, indicating discontinued manufacturing. Selection of this substitute is appropriate only when supply of the primary part is unavailable and existing inventory is accessible. The REACH Unaffected status indicates compliance with chemical substance regulations. The Natural color variant does not affect electrical performance or mechanical fit within standard connector assemblies.

Compliance Considerations

Both parts share identical electrical specifications, temperature ratings, and insulation material composition. The primary part's explicit RoHS Compliance certification provides regulatory assurance for new designs. The substitute part's Obsolete status requires verification of remaining inventory availability before design commitment.

Frequently Asked Questions (FAQ)

Q: Can 1-770602-1 be used as a direct replacement for 1-1375820-1 in new designs?

A: The 1-770602-1 provides electrical and mechanical equivalence across all critical parameters. However, Obsolete product status limits long-term availability. New designs should specify the Active 1-1375820-1 to ensure supply continuity and manufacturer support.

Q: Does the color difference between White (1-1375820-1) and Natural (1-770602-1) affect connector performance?

A: Color is a cosmetic attribute determined by insulation material pigmentation. Both parts use identical Polyamide (PA) Nylon Glass Filled insulation. Color does not affect electrical conductivity, mechanical strength, or temperature performance.

Q: Are the CST-100 II and CST-100 series housings mechanically compatible?

A: Both series maintain identical pitch (0.100"), position count (11), row configuration (1), and fastening mechanism (Locking Ramp). Mechanical compatibility is confirmed across all mounting and contact interfaces.

Q: What is the significance of Moisture Sensitivity Level (MSL) 1 for both parts?

A: MSL 1 designation indicates Unlimited shelf life without moisture control requirements. Both parts do not require desiccant packaging or controlled humidity storage conditions.

Q: Are contacts included with these connector housings?

A: No. Both the 1-1375820-1 and 1-770602-1 are housings only. Female socket contacts must be procured separately and installed via crimp termination.

Q: What is the difference between REACH Unaffected and Vendor Undefined status?

A: REACH Unaffected indicates the part composition does not trigger REACH chemical substance reporting requirements. Vendor Undefined indicates the manufacturer has not provided explicit REACH compliance documentation. For regulatory compliance verification, contact the manufacturer directly.

Q: Can these 11-position housings accommodate different contact quantities?

A: No. These housings are designed specifically for 11-position configurations. The housing structure and internal cavity arrangement are fixed at 11 positions with 0.100" pitch spacing.
